Scroll Textview inside RecyclerView

Scroll Textview inside RecyclerView - android

I have a RecyclerView
<android.support.v7.widget.RecyclerView
android:id="#+id/activityRecicler"
android:layout_width="match_parent"
android:scrollbars="vertical"
android:layout_height="wrap_content"
app:stackFromEnd="true"
/>
And I have a row layout:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/description"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/solutions"/>
</LinearLayout>
And the wrap content work, but my problem is that TextView with id description It could be very long and so, I would have a Scroll for this TextView.
How could I do this?

Change your layout XML to:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<ScrollView
android:id="#+id/scroll_view"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="#+id/description"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</ScrollView>
<TextView
android:id="#+id/solutions"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
And then in your activity:
recyclerView.setOnTouchListener(new View.OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
findViewById(R.id.scroll_view).getParent().requestDisallowInterceptTouchEvent(false);
return false;
}
});
scrollView.setOnTouchListener(new View.OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
// Disallow the touch request for parent scroll on touch of child view
v.getParent().requestDisallowInterceptTouchEvent(true);
return false;
}
});

I am beginner on Android and so I don't know if my solution it's good.
I have put in Layout Row as suggested by #Payal
<ScrollView
android:id="#+id/childScroll"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="#+id/solutions"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:text="long_text"
android:maxLines="5"
android:scrollbars="vertical"/>
</ScrollView>
And in My ViewHolder
public ViewHolder(View itemView) {
super(itemView);
solutions = (TextView) itemView.findViewById(R.id.solutions);
description = (TextView) itemView.findViewById(R.id.description);
scrollable = (ScrollView) itemView.findViewById(R.id.childScroll);
solutions.setOnTouchListener(new View.OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
// Disallow the touch request for parent scroll on touch of child view
v.getParent().requestDisallowInterceptTouchEvent(true);
return false;
}
});
//Enabling scrolling on TextView.
solutions.setMovementMethod(new ScrollingMovementMethod());
}
And it's work.
I can scroll the TextView in my RecyclerView

Try below code on your textview id in viewholder.
scrollable = (TextView)findViewById(R.id.textView1);
//Enabling scrolling on TextView.
scrollable.setMovementMethod(new ScrollingMovementMethod());
add in TextViewlayout
android:scrollbars="vertical"

rowlayout.xml
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
>
<TextView
android:id="#+id/description"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:ellipsize="marquee"
android:fadingEdge="horizontal"
android:lines="1"
android:marqueeRepeatLimit="marquee_forever"
android:scrollHorizontally="true"
android:singleLine="true"
android:textColor="#ff4500" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/solutions"/>
</LenearLayout>
and in activity
descrptionTextview.setSelected(true);

either you can wrap it in scrollview like this
<ScrollView
android:layout_height="100px"
android:layout_width="fill_parent">
<TextView
android:id="#+id/text_view"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:text="long_text"/>
</ScrollView>
or
add these two attributes to yout textview
android:maxLines="5"
android:scrollbars="vertical"
and add below line in your code
textview.setMovementMethod(new ScrollingMovementMethod());
hope this helps :)

Make a new class
public class AutoScrollingTextView extends TextView {
public AutoScrollingTextView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
public AutoScrollingTextView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public AutoScrollingTextView(Context context) {
super(context);
}
#Override
protected void onFocusChanged(boolean focused, int direction, Rect previouslyFocusedRect) {
if (focused) {
super.onFocusChanged(focused, direction, previouslyFocusedRect);
}
}
#Override
public void onWindowFocusChanged(boolean focused) {
if (focused) {
super.onWindowFocusChanged(focused);
}
}
#Override
public boolean isFocused() {
return true;
}
}
Then in xml
<AutoScrollingTextView
android:scrollHorizontally="true"
android:ellipsize="marquee"
android:marqueeRepeatLimit="marquee_forever"/>
This works !!!

RecyclerView grid layout manager doesn't center items

I inherited some big project with a lot of legacy code and now I'm facing some weird stuff..
I need to make this screen have recyclerview with grid layout manager, 2 columns. This is what I get. Is there a way to center those icons in the middle of the screen? I tried with gravity, but nothing works. Maybe there is some thing inside all that legacy code that is making problem or this is just recyclerView's issue?
This is the item's layout (terrible, don't ask..)
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:descendantFocusability="blocksDescendants">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/color_view_controller_item_background"
android:orientation="vertical">
<TextView
android:id="#+id/textViewSceneKK"
android:layout_width="match_parent"
android:layout_height="#dimen/room_button_height"
android:layout_gravity="center"
android:layout_marginLeft="#dimen/row_filter_text_margin_left"
android:layout_marginRight="#dimen/row_filter_text_margin_left"
android:gravity="center"
android:shadowDx="-1"
android:shadowDy="-1"
android:shadowRadius="1"
android:textSize="#dimen/row_scene_kk_text_size" />
<TextView
android:id="#+id/textViewSceneName"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="#dimen/row_filter_text_margin_bottom"
android:layout_marginLeft="#dimen/row_filter_text_margin_left"
android:layout_marginRight="#dimen/row_filter_text_margin_left"
android:layout_marginTop="#dimen/row_filter_text_margin_top"
android:clickable="false"
android:gravity="center"
android:longClickable="false"
android:textColor="#color/main_text_color"
android:textSize="#dimen/row_browser_right_name_text_size" />
</LinearLayout>
<!--<View-->
<!--android:id="#+id/filterView"-->
<!--android:layout_width="match_parent"-->
<!--android:layout_height="match_parent"-->
<!--android:clickable="false"-->
<!--android:longClickable="false" />-->
<View
android:id="#+id/filterViewClick"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="?android:selectableItemBackground"
android:focusable="false"
android:focusableInTouchMode="false" />
And fragment't layout:
<customview.CustomRecyclerView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scrollbars="none" />
And the code:
customRecyclerView.setHasFixedSize(false);
customRecyclerView.setLayoutManager(new GridLayoutManager(getContext(), 2));
customRecyclerView.addItemDecoration(new DividerItemDecoration(getContext(),
R.drawable.line_separator_empty, DividerItemDecoration.VERTICAL_LIST));
customRecyclerView.setAdapter(adapter);
CustomRecyclerView.java
public class CustomRecyclerView extends RecyclerView {
private boolean enableScroll = true;
public CustomRecyclerView(Context context) {
super(context);
}
public CustomRecyclerView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public CustomRecyclerView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
public boolean isEnableScroll() {
return enableScroll;
}
public void setEnableScroll(boolean enableScroll) {
this.enableScroll = enableScroll;
}
#Override
public int computeVerticalScrollRange() {
return super.computeVerticalScrollRange();
}
#Override
public boolean onInterceptTouchEvent(MotionEvent e) {
if (enableScroll) {
return super.onInterceptTouchEvent(e);
}
return false;
}
}

You have to use layout gravity to make it center & need to change match-parent to wrap_content, also you have to assign layout gravity runtime. try this code:
Adapter item layout:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:descendantFocusability="blocksDescendants"
android:orientation="vertical">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="right"
android:id="#+id/top_header_rl"
android:background="#color/app_header_color"
android:orientation="vertical">
<TextView
android:id="#+id/textViewSceneKK"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:gravity="center"
android:shadowDx="-1"
android:shadowDy="-1"
android:shadowRadius="1"
android:text="Heder name"
android:textSize="26sp" />
<TextView
android:id="#+id/textViewSceneName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:clickable="false"
android:gravity="center"
android:text="Footer name"
android:longClickable="false"
android:textSize="25sp" />
</LinearLayout>
<!--<View-->
<!--android:id="#+id/filterView"-->
<!--android:layout_width="match_parent"-->
<!--android:layout_height="match_parent"-->
<!--android:clickable="false"-->
<!--android:longClickable="false" />-->
<View
android:id="#+id/filterViewClick"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:background="?android:selectableItemBackground"
android:focusable="false"
android:focusableInTouchMode="false" />
</FrameLayout>
Adapter Code:
public class CenterGridView extends RecyclerView.Adapter<CenterGridView.CenterGridViewViewHolder> {
private Context context;
public CenterGridView(Context context){
this.context =context;
}
#Override
public CenterGridViewViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
return new CenterGridViewViewHolder(LayoutInflater.from(context).inflate(R.layout.new_tiem,parent,false));
}
#Override
public void onBindViewHolder(CenterGridViewViewHolder holder, int position) {
if(position%2==0){
FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(FrameLayout.LayoutParams.WRAP_CONTENT, FrameLayout.LayoutParams.WRAP_CONTENT);
params.gravity = Gravity.RIGHT;
holder.top_header_rl.setLayoutParams(params);
}else{
FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(FrameLayout.LayoutParams.WRAP_CONTENT, FrameLayout.LayoutParams.WRAP_CONTENT);
params.gravity = Gravity.LEFT;
holder.top_header_rl.setLayoutParams(params);
}
}
#Override
public int getItemCount() {
return 20;
}
class CenterGridViewViewHolder extends RecyclerView.ViewHolder{
private LinearLayout top_header_rl;
public CenterGridViewViewHolder(View itemView) {
super(itemView);
top_header_rl = (LinearLayout)itemView.findViewById(R.id.top_header_rl);
}
}
}
Main Activity layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_horizontal"
android:orientation="vertical">
<com.demostudies.CustomRecyclerView
android:id="#+id/tests"
android:layout_width="wrap_content"
android:layout_height="wrap_content"></com.demostudies.CustomRecyclerView>
</LinearLayout>
// Set Adapter
CustomRecyclerView customRecyclerView = (CustomRecyclerView)findViewById(R.id.tests);
customRecyclerView.setHasFixedSize(false);
customRecyclerView.setLayoutManager(new GridLayoutManager(this, 2));
customRecyclerView.setAdapter(new CenterGridView(this));

try this:
it's working for me
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal|center_vertical"

OnTouchListener on LinearLayout that is behind buttons

I am working on an Android application using C# in Xamarin. In my axml file, I have a LinearLayout with a certain ID that I have assigned a onTouchListener to. The problem is that as long as the buttons I have in my design are on top of the linearLayout, the onTouchListener is never triggered. If I set one of the buttons to invisible, then it works.
Is it possible to still have the onTouchListener react even though there are Controls in the way?
This is my axml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/LinearLayout1"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:orientation="vertical">
<LinearLayout
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:orientation="horizontal"
android:layout_weight="1">
<Button
android:id="#+id/button1"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:text="1"
android:layout_marginBottom="0.0dp"
android:background="#android:color/holo_green_light"
android:soundEffectsEnabled="false" />
<Button
android:id="#+id/button2"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:text="2"
android:background="#android:color/holo_blue_light" />
</LinearLayout>
<LinearLayout
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_weight="1">
<Button
android:id="#+id/button3"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:text="3"
android:background="#android:color/holo_red_light" />
<Button
android:id="#+id/button4"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:text="4"
android:background="#android:color/holo_orange_light" />
</LinearLayout>
</LinearLayout>
This is how I set the onTouchlistener for the linearLayout:
LinearLayout linLay = FindViewById<LinearLayout>(Resource.Id.LinearLayout1);
linLay.SetOnTouchListener(new MyTouchListener(this));
This is a custom touch listener class:
public class MyTouchListener : Java.Lang.Object, View.IOnTouchListener
{
Context activityContext;
public MyTouchListener(Context ac)
{
activityContext = ac;
}
public bool OnTouch(View v, MotionEvent e)
{
float x = 0.0f;
float y = 0.0f;
if (e.Action == MotionEventActions.Down)
{
// do stuff
x = e.GetX();
y = e.GetY();
Toast.MakeText(activityContext, x.ToString(), ToastLength.Short).Show();
return true;
}
//if (e.Action == MotionEventActions.Up)
//{
// // do other stuff
// return true;
//}
return true;
}
}
And finally, this is how I set up the button click listener:
Button button = FindViewById<Button>(Resource.Id.button1);
button.Click += (s,e) =>
{
//int i = count % s.Count;
//if(i > 28)
// Toast.MakeText(this, button.GetX().ToString(), ToastLength.Short).Show();
button.Text = string.Format("{0}", count++);
};

You have to intercept the touch event. In order to do that you have to subclass LinearLayout and override onInterceptTouchEvent():
public class MyLinearLayout extends LinearLayout {
public MyLinearLayout(Context context) {
super(context);
}
public MyLinearLayout(Context context, #Nullable AttributeSet attrs) {
super(context, attrs);
}
public MyLinearLayout(Context context, #Nullable AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
#Override
public boolean onTouchEvent(MotionEvent event) {
Toast.makeText(getContext(), "onTouch", Toast.LENGTH_SHORT).show();
return true;
}
#Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
return true;
}
}
Your xml:
<?xml version="1.0" encoding="utf-8"?>
<com.your.package.MyLinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/LinearLayout1"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:orientation="vertical">
<LinearLayout
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:orientation="horizontal"
android:layout_weight="1">
<Button
android:id="#+id/button1"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:text="1"
android:layout_marginBottom="0.0dp"
android:background="#android:color/holo_green_light"
android:soundEffectsEnabled="false" />
<Button
android:id="#+id/button2"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:text="2"
android:visibility="invisible"
android:background="#android:color/holo_blue_light" />
</LinearLayout>
<LinearLayout
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_weight="1">
<Button
android:id="#+id/button3"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:text="3"
android:background="#android:color/holo_red_light" />
<Button
android:id="#+id/button4"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:text="4"
android:background="#android:color/holo_orange_light" />
</LinearLayout>
</com.your.package.MyLinearLayout>
Now any touch event on the layout will be handled by your custom MyLinearLayout.

You need to extend (inherent) the parent linear layout so that you can intercept touch events from the nested children layouts. Override these two methods to receive touches from the children. Then in your xml you will add "myCustomLinearLayout" or whatever you name the your custom linear layout class. It should be pretty similar in C# / Xamarin.
#Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
return true; // With this i tell my layout to consume all the touch events from its childs
}
#Override
public boolean onTouchEvent(MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
// Log.d(TAG, String.format("ACTION_DOWN | x:%s y:%s",
break;
case MotionEvent.ACTION_MOVE:
//Log.d(TAG, String.format("ACTION_MOVE | x:%s y:%s",
break;
case MotionEvent.ACTION_UP:
break;
}
return true;
}

How to scroll the edittext inside the scrollview

I have a scrollview inside which there is a editext which is multiline. I want to scroll the edittext to see the lower content but it can't be done.

Can you guys help me in that . I think editText is getting the focus when cursor is inside it.
Thanks..!!!!!

Try this..
Add below lines into your EditText
android:overScrollMode="always"
android:scrollbarStyle="insideInset"
android:scrollbars="vertical"
Example
<EditText
android:id="#+id/editText1"
android:layout_width="match_parent"
android:layout_height="200dp"
android:layout_marginTop="15dp"
android:background="#eeeeee"
android:inputType="textMultiLine"
android:singleLine="false"
android:overScrollMode="always"
android:scrollbarStyle="insideInset"
android:scrollbars="vertical"
android:text="Android applications normally run entirely on a single thread by default the “UI thread” or the “main thread”.
android:textAppearance="?android:attr/textAppearanceMedium" >
</EditText>
EDIT
Programmatically
youredittext.setOnTouchListener(new OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
if (youredittext.hasFocus()) {
v.getParent().requestDisallowInterceptTouchEvent(true);
switch (event.getAction() & MotionEvent.ACTION_MASK){
case MotionEvent.ACTION_SCROLL:
v.getParent().requestDisallowInterceptTouchEvent(false);
return true;
}
}
return false;
}
});

First add this at XML
android:scrollbarStyle="insideInset"
android:scrollbars="vertical"
android:overScrollMode="always"
Then add the same above "OnTouch" but make it return "false" not "true"
public boolean onTouch(View view, MotionEvent event) {
if (view.getId() == R.id.DwEdit) {
view.getParent().requestDisallowInterceptTouchEvent(true);
switch (event.getAction()&MotionEvent.ACTION_MASK){
case MotionEvent.ACTION_UP:
view.getParent().requestDisallowInterceptTouchEvent(false);
break;
}
}
return false;
}

Kotlin version
Add the following lines to the EditText in your xml:
android:overScrollMode="always"
android:scrollbarStyle="insideInset"
android:scrollbars="vertical"
Add this to the Activity/Fragment:
myEditText.setOnTouchListener { view, event ->
view.parent.requestDisallowInterceptTouchEvent(true)
if ((event.action and MotionEvent.ACTION_MASK) == MotionEvent.ACTION_UP) {
view.parent.requestDisallowInterceptTouchEvent(false)
}
return#setOnTouchListener false
}

Use this code it's working
In XML
android:singleLine="false"
android:overScrollMode="always"
android:scrollbarStyle="insideInset"
android:scrollbars="vertical"
In programming
edittext.setOnTouchListener(new View.OnTouchListener() {
public boolean onTouch(View view, MotionEvent event) {
if (view.getId() == R.id.edittext) {
view.getParent().requestDisallowInterceptTouchEvent(true);
switch (event.getAction() & MotionEvent.ACTION_MASK) {
case MotionEvent.ACTION_UP:
view.getParent().requestDisallowInterceptTouchEvent(false);
break;
}
}
return false;
}
});

you should use NestedScrollView class. This class support child scrolling inside parent scrolling. This class can be a child or a parent.
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#d6d8d9">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:maxLines="512"
android:text=" your content"/>
<android.support.v4.widget.NestedScrollView
android:layout_below="#id/ll_button"
android:layout_width="match_parent"
android:layout_height="300dp"
android:background="#d6d8d9">
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="your content"
android:maxLines="512"/>
</android.support.v4.widget.NestedScrollView>
</LinearLayout>
</android.support.v4.widget.NestedScrollView>

Building upon the answer by #Ayman Mahgoub and #Hariharan. The solution worked great except while scrolling the edit text there is no scroll momentum. As soon as the finger lifts up, the scrolling immediately stops.
To gain scroll momentum wrap a scrollview around the EditText and let the EditText's height wrap content (set minHeight if you'd like). Remove the following lines from the edit text:
android:scrollbarStyle="insideInset"
android:scrollbars="vertical"
android:overScrollMode="always"
Now the nested ScrollView wrapped around the EditText takes care of the scrolling. Update the onTouch handler to take into account the updated view hierarchy:
public boolean onTouch(View view, MotionEvent event) {
v.getParent().getParent().requestDisallowInterceptTouchEvent(true);
switch (event.getAction() & MotionEvent.ACTION_MASK){
case MotionEvent.ACTION_UP:
v.getParent().getParent().requestDisallowInterceptTouchEvent(false);
break;
}
return false;
Be warned, this solution is now tightly coupled to the view hierarchy.

I would vote up the updated answer provided by #Ayman Mahgoub, but I do not have a high enough reputation. His code works. I had to change return true to return false. You put the .setOnTouchListener() method in your java class and put the three lines:
android:scrollbarStyle="insideInset"
android:scrollbars="vertical"
android:overScrollMode="always"
in the corresponding xml file. You can see the implementation in the android emulator, and on the android phone you use for testing. Thank you so much #Ayman Mahgoub and #Hariharan!

This will scroll the EditText and make it editable:
First in the XML file, add this:
android:overScrollMode="always"
android:scrollbarStyle="insideInset"
android:scrollbars="vertical"
Then in the Java file, add this:
EditText.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View view, MotionEvent motionEvent) {
view.getParent().requestDisallowInterceptTouchEvent(true);
switch (motionEvent.getAction() & MotionEvent.ACTION_MASK) {
case MotionEvent.ACTION_SCROLL:
view.getParent().requestDisallowInterceptTouchEvent(false);
return true;
case MotionEvent.ACTION_BUTTON_PRESS:
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(EditText, InputMethodManager.SHOW_IMPLICIT);
}
return false;
}
});

The simplest way is by doing Extention in Kotlin:
First add this extension:
fun EditText.enableScrollText()
{
overScrollMode = View.OVER_SCROLL_ALWAYS
scrollBarStyle = View.SCROLLBARS_INSIDE_INSET
isVerticalScrollBarEnabled = true
setOnTouchListener { view, event ->
if (view is EditText) {
if(!view.text.isNullOrEmpty()) {
view.parent.requestDisallowInterceptTouchEvent(true)
when (event.action and MotionEvent.ACTION_MASK) {
MotionEvent.ACTION_UP -> view.parent.requestDisallowInterceptTouchEvent(false)
}
}
}
false
}
}
and finally easily call this for your edittext:
editText.enableScrollText();
This extention works well in any case like inside ScrollView or RecyclerView or BottomSheet

Below Answer will help you to make Edit Text scrollable inside Scroll View and also show Count of it.
1.Make one rectangle_with_border_gray.xml file in #drawable folder.
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners android:radius="0dp"/>
<solid android:color="#FFFFFF"/>
<stroke android:color="#7f848686"
android:width="0.01dp"/>
</shape>
2.Then, In #layout write below code in scroll view.
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="none">
<RelativeLayout
android:id="#+id/sv_profile_creation_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#FFFFFF">
<LinearLayout
android:id="#+id/LL_optional_message"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/tv_optional_message_title"
android:background="#drawable/rectangle_with_border_gray"
android:orientation="horizontal"
android:padding="#dimen/margin_02_dp">
<EditText
android:id="#+id/et_optional_message"
android:layout_width="match_parent"
android:layout_height="100dp"
android:background="#color/colorWhite"
android:gravity="start"
android:hint="#string/why_not_leave_a_message"
android:inputType="textMultiLine"
android:isScrollContainer="true"
android:maxLines="5"
android:overScrollMode="always"
android:padding="8dp"
android:scrollbarStyle="insideInset"
android:scrollbars="vertical"
android:textColor="#color/colorEditTextHintNormal"
android:textColorHint="#color/colorEditTextHint"
android:textSize="#dimen/margin_14_dp" />
</LinearLayout>
<TextView
android:id="#+id/tv_description_count"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_below="#+id/LL_optional_message"
android:layout_centerVertical="true"
android:layout_marginBottom="#dimen/margin_16_dp"
android:ellipsize="end"
android:gravity="center"
android:maxLines="1"
android:text="0/200"
android:textColor="#color/colorLittleDarkGray"
android:textSize="#dimen/margin_12_dp"
android:textStyle="normal" />
</RelativeLayout>
</ScrollView>
3.Then, Inside your Activity or Fragment write below code:
TextView tv_description_count = (TextView) view.findViewById(R.id.tv_description_count);
EditText et_optional_message = (EditText) findViewById(R.id.et_optional_message);
private void makeScrollable(){
et_optional_message.addTextChangedListener(mTextEditorWatcher);
et_optional_message.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View view, MotionEvent motionEvent) {
view.getParent().requestDisallowInterceptTouchEvent(true);
switch (motionEvent.getAction() & MotionEvent.ACTION_MASK) {
case MotionEvent.ACTION_SCROLL:
view.getParent().requestDisallowInterceptTouchEvent(false);
return true;
case MotionEvent.ACTION_BUTTON_PRESS:
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(et_optional_message, InputMethodManager.SHOW_IMPLICIT);
}
return false;
}
});
}
private final TextWatcher mTextEditorWatcher = new TextWatcher() {
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
public void onTextChanged(CharSequence s, int start, int before, int count) {
//This sets a textview to the current length
tv_description_count.setText(String.valueOf(s.length()));
}
public void afterTextChanged(Editable s) {
}
};
Happy Coding......

First create a custom Scrollview class as given below:
import android.content.Context;
import android.util.AttributeSet;
import android.util.Log;
import android.view.MotionEvent;
import android.widget.ScrollView;
public class MyCustomScrollview extends ScrollView {
public VerticalScrollview(Context context) {
super(context);
}
public VerticalScrollview(Context context, AttributeSet attrs) {
super(context, attrs);
}
public VerticalScrollview(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
#Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
final int action = ev.getAction();
switch (action)
{
case MotionEvent.ACTION_DOWN:
Log.i("VerticalScrollview", "onInterceptTouchEvent: DOWN super false" );
super.onTouchEvent(ev);
break;
case MotionEvent.ACTION_MOVE:
return false; // redirect MotionEvents to ourself
case MotionEvent.ACTION_CANCEL:
Log.i("VerticalScrollview", "onInterceptTouchEvent: CANCEL super false" );
super.onTouchEvent(ev);
break;
case MotionEvent.ACTION_UP:
Log.i("VerticalScrollview", "onInterceptTouchEvent: UP super false" );
return false;
default: Log.i("VerticalScrollview", "onInterceptTouchEvent: " + action ); break;
}
return false;
}
#Override
public boolean onTouchEvent(MotionEvent ev) {
super.onTouchEvent(ev);
Log.i("VerticalScrollview", "onTouchEvent. action: " + ev.getAction() );
return true;
}
}
Now in the activity or fragment where you are using the EditText, write the following code for the EditText object that you want to scroll inside the Scrollview :
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.MotionEvent;
import android.view.View;
import android.widget.EditText;
public class MainActivity extends AppCompatActivity {
EditText et;
VerticalScrollview sv;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
init();
}
private void init() {
sv = findViewById(R.id.sv);
et = findViewById(R.id.et);
et.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
if (v.getId() == R.id.sv) {
v.getParent().requestDisallowInterceptTouchEvent(true);
switch (event.getAction() & MotionEvent.ACTION_MASK) {
case MotionEvent.ACTION_UP:
v.getParent().requestDisallowInterceptTouchEvent(false);
break;
}
}
return false;
}
});
}
}
3.The follwing xml is given below:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".MainActivity">
<com.example.ayan.scrollableedittext.VerticalScrollview
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/sv">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="600dp"
android:gravity="center">
<EditText
android:id="#+id/et"
android:layout_width="200dp"
android:layout_height="80dp"
android:nestedScrollingEnabled="true"
android:gravity="start" />
</LinearLayout>
</LinearLayout>
</com.example.ayan.scrollableedittext.VerticalScrollview>
</LinearLayout>

Thanks to Hariharan, vovahost I got the same solution, but added performClick() to avoid a warning.
EditText (XML):
android:overScrollMode="always"
android:scrollbarStyle="insideInset"
android:scrollbars="vertical"
Code:
edit_text.setOnTouchListener { view, event ->
view.parent.requestDisallowInterceptTouchEvent(true)
if ((event.action and MotionEvent.ACTION_MASK) == MotionEvent.ACTION_SCROLL) {
view.parent.requestDisallowInterceptTouchEvent(false)
} else {
performClick()
}
return#setOnTouchListener false
}

Add this method in main activity:
It worked for me in Fragment
#Override
public boolean dispatchTouchEvent(MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
View v = getCurrentFocus();
if (v instanceof EditText) {
Rect outRect = new Rect();
v.getGlobalVisibleRect(outRect);
if (!outRect.contains((int) event.getRawX(), (int) event.getRawY())) {
v.clearFocus();
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(v.getWindowToken(), 0);
}
}
}
return super.dispatchTouchEvent(event);
}

ScrollView scrolls when content fits on screen

I'm having an issue where I have a ScrollView content inside of it. In the event that the content doesn't all fit on screen, I want it to scroll. However, if it all fits I don't want it to scroll.
As is, the scrollviewer scrolls quite a bit and all the content can be scrolled way off screen.
How does one get the scrollview to not scroll when all the content fits on the screen?
<ScrollView
android:minWidth="25px"
android:minHeight="25px"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:layout_toRightOf="#id/productImageView"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:id="#+id/detailsScrollView"
android:paddingRight="24dp"
android:paddingLeft="24dp"
android:clipChildren="true"
android:fillViewport="true"
android:measureAllChildren="true">
<LinearLayout
android:orientation="vertical"
android:minWidth="25px"
android:minHeight="25px"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/linearLayout1"
android:paddingTop="24dp"
android:paddingBottom="24dp">
<TextView
android:textAppearance="?android:attr/textAppearanceLarge"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/patternTitleTextView" />
<TextView
android:textAppearance="?android:attr/textAppearanceMedium"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/designerNameTextView"
android:textColor="#color/default_gray" />
<TextView
android:textAppearance="?android:attr/textAppearanceSmall"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/descriptionTextView"
android:layout_marginTop="12dp"
android:layout_weight="1"
android:minLines="200"
android:scrollbars="none"
android:scrollHorizontally="false"
android:singleLine="false"
android:ellipsize="none" />
</LinearLayout>
</ScrollView>

You probably need to create a custom ScrollView:
import android.content.Context;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.widget.ScrollView;
public class CustomScrollView extends ScrollView {
private boolean enableScrolling = true;
public boolean isEnableScrolling() {
return enableScrolling;
}
public void setEnableScrolling(boolean enableScrolling) {
this.enableScrolling = enableScrolling;
}
public CustomScrollView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
public CustomScrollView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public CustomScrollView(Context context) {
super(context);
}
#Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
if (isEnableScrolling()) {
return super.onInterceptTouchEvent(ev);
} else {
return false;
}
}
}
Then you can do something similar to this in your code:
CustomScrollView myScrollView = (CustomScrollView) findViewById(R.id.myScroll);
myScrollView.setEnableScrolling(false); // disable scrolling
myScrollView.setEnableScrolling(true); // enable scrolling
Of course, it will be up to you to decide when exactly you need to enable/disable scrolling.

The problem in my case was with one of the TextViews.
<TextView
android:textAppearance="?android:attr/textAppearanceSmall"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/descriptionTextView"
android:layout_marginTop="12dp"
android:layout_weight="1"
android:minLines="200"
android:scrollbars="none"
android:scrollHorizontally="false"
android:singleLine="false"
android:ellipsize="none" />
I shouldn't have set minLines or set the layout_weight. After removing those two things the scrollview did exactly what I expected it to.

ScrollBar doesnt work in EditText

Hope all of you doing well.
My Problem is:
I have xml code like following:
<?xml version="1.0" encoding="utf-8"?>

</LinearLayout>
</ScrollView>
In that i have two EditText in </ScrollView>, Second <EditText/> does not scrolling inner side. Problem is Full View is scrolled while i am scrolling but i want to also scroll vertically in second EditText when user enter more than 5 lines. In that ScrollBar is displaying but not scrolling.
How can i solve this.
Your Help would be appreciated.

This code should work.....
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
findViewById(R.id.parentScrollView).setOnTouchListener(parentListener);
findViewById(R.id.custDetailsDescEditText).setOnTouchListener(childListener);
}
OnTouchListener parentListener = new OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
findViewById(R.id.custDetailsDescEditText).getParent()
.requestDisallowInterceptTouchEvent(false);
return false;
}
};
OnTouchListener childListener = new View.OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
v.getParent().requestDisallowInterceptTouchEvent(true);
return false;
}
};

Try something like this in your code
ScrollView scroller = new ScrollView(this);
EditText et=(EditText)findViewById(R.id.yourEdittext);
scroller.addView(et);
