Use this code to resolve your problem
<androidx.core.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"

You must be use CUSTOM viewpager to achieve vertical scrolling of viewpager because default viewpager doesn't support vertical scrolling with other components.
Check my below code.
public class CustomViewPager extends ViewPager {
private View mCurrentView;
public CustomViewPager(Context context) {
super(context);
}
public CustomViewPager(Context context, AttributeSet attrs) {
super(context, attrs);
}
#Override
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
if (mCurrentView == null) {
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
return;
}
int height = 0;
mCurrentView.measure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
int h = mCurrentView.getMeasuredHeight();
if (h > height) height = h;
heightMeasureSpec = MeasureSpec.makeMeasureSpec(height, MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
public void measureCurrentView(View currentView) {
mCurrentView = currentView;
requestLayout();
}
public int measureFragment(View view) {
if (view == null)
return 0;
view.measure(0, 0);
return view.getMeasuredHeight();
}
}
Apply this Class instead of default ViewPager into your fragment. THAT'S IT!!

I want the entire activity to be scrollable but only listview is scrollable. How do I do that?

I pull data into my listview from servers. The listview is inside an activity. The activity has buttons above it.
When the data is received and when I scroll data, only listview is scrolled. The buttons remain fixed at the top.
I want the listview to take the required vertical height it needs so that I would need to scroll the activity instead of the listview.
My XML code :
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<TextView
android:text="text1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/view_c_name"
android:textSize="18sp"
android:textStyle="bold"/>
<TextView
android:text="text4"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/view_c_name"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:id="#+id/view_c_motto" />
<TextView
android:text="text5"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/view_c_motto"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:id="#+id/view_c_details" />
<TextView
android:text="text2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/view_c_address"
android:layout_below="#+id/view_c_details"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true" />
<TextView
android:text="text3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/view_c_act_text"
android:layout_below="#+id/view_c_address"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_marginTop="71dp" />
<Button
android:text="Button 1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="16dp"
android:layout_marginStart="16dp"
android:id="#+id/view_button"
android:layout_below="#+id/view_c_address"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true" />
<Button
android:text="button 2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/view_button"
android:layout_toRightOf="#+id/view_button"
android:layout_toEndOf="#+id/view_button"
android:layout_marginLeft="16dp"
android:layout_marginStart="16dp"
android:id="#+id/view_button2" />
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/view_c_act_text"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:id="#+id/my_listview"
android:scrollbars="none"
/>
</RelativeLayout>

The perfect code should be;
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<!--Inside the below layout your buttons will come. Modify it accordingly-->
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<!--Your buttons will come here-->
</LinearLayout>
<ListView
android:id="#+id/listView"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
</android.support.v4.widget.NestedScrollView>
As shown above, Nested Scroll View should be used instead of Scroll View because
there is a need of scrolling view (in this case List View) inside another scrolling view. The system is unable to decide which view to scroll and this is where Nested Scroll View comes in.

Wrap your existing layout in a ScrollView to scroll the entire thing, not just the ListView
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- your existing layout here, change your top container's height from match_parent to wrap_content -->
</ScrollView>

Try this one
<ScrollView
android:id="#+id/scrollViewMain"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:id="#+id/linearLayoutMain"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<Button
android:text="Button"
android:id="#+id/buttonMain"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</LinearLayout>
</ScrollView>

<RelativeLayout
android:layout_width="match_parent">
android:layout_height="match_parent">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
"your existing layout here, change your top container's height from match_parent or wrap_content "
the best case secanrio is to use scroll View inside of an relative layout and all the existing code inside of the scrollView

I had similar problem then I created a class
public class ListViewExpanded extends ListView {
public ListViewExpanded(Context context, AttributeSet attrs) {
super(context, attrs);
setDividerHeight(0);
}
#Override
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
super.onMeasure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST));
}
}
then I used in xml as try it out it will help for sure
<android.support.v4.widget.NestedScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<TextView
android:id="#+id/text_goal_scored"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
<example.ListViewExpanded
android:id="#+id/list_home"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1">
</example.ListViewExpanded>
</android.support.v4.widget.NestedScrollView>

Go through this Example. Make ScroolView as Parent. It Work Form me.
<ScrollView android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
xmlns:android="http://schemas.android.com/apk/res/android">

android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".MainActivity">

android:layout_width="match_parent"

<TextView
android:id="#+id/text"
android:layout_width="wrap_content"

<RelativeLayout

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="20dp"
android:paddingLeft="10dp"
android:paddingRight="10dp">
<TextView
android:id="#+id/text2"
android:layout_width="wrap_content"

</RelativeLayout>
</LinearLayout>
</ScroolView>

this is how you can do your task.this is Scroll disabled listview so you can scroll your activity easily.

}
ViewGroup.LayoutParams params = listView.getLayoutParams();
params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
listView.setLayoutParams(params);

The problem is that when I inflate this recyclerView, the complete activity is not scrolling (Only the part of recycler view does). Moreover I have specify height of recyclerView otherwise I am not able to see it.
So my two problems are:
How to give this RecyclerView hight dynamically (layout_height: wrap_content isn't working)
How to scroll the entire activity (and not just the recyclerView part) when content is more.
P.S I am new to Android, though I have implemented recyclerView earlier but in those cases there was only one element (one recyclerView inside a parent LinearLayout)

ExpandableHeightListView.java
import android.util.AttributeSet;
import android.view.ViewGroup;
import android.widget.ListView;
import android.content.Context;
public class ExpandableHeightListView extends ListView
{
boolean expanded = false;
public ExpandableHeightListView(Context context)
{
super(context);
}
public ExpandableHeightListView(Context context, AttributeSet attrs)
{
super(context, attrs);
}
public ExpandableHeightListView(Context context, AttributeSet attrs,
int defStyle)
{
super(context, attrs, defStyle);
}
public boolean isExpanded()
{
return expanded;
}
#Override
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec)
{
if (isExpanded())
{
// Calculate entire height by providing a very large height hint.
// But do not use the highest 2 bits of this integer; those are
// reserved for the MeasureSpec mode.
int expandSpec = MeasureSpec.makeMeasureSpec(
Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, expandSpec);
ViewGroup.LayoutParams params = getLayoutParams();
params.height = getMeasuredHeight();
}
else
{
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
}
public void setExpanded(boolean expanded)
{
this.expanded = expanded;
}
}
Add this customized java file and use it in xml.
and in your MainActivity do like this:
ExpandableHeightListView listview= (ExpandableHeightListView) findViewById(R.id.comment_listview);
and set adapter and set one property
listview.setAdapter("Your Adapter");
listview.setExpanded(true);

Android FrameLayout position using Fragment

android:gravity="left"
android:text="#string/Generic_Button_Cancel"
android:textColor="#color/processStepCategoryTextColor" />
</RelativeLayout>
</LinearLayout>
</RelativeLayout>
The TutorialFragment object uses this layout :
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<android.support.v4.view.ViewPager
android:id="#+id/tutorial_viewpager"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
No matter what I try, this FrameLayout is always aligned on top of the screen, and I need it to be at the bottom of the screen.

Try by change your layout like this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<RelativeLayout
android:id="#+id/relLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:orientation="vertical"
android:padding="0dp"
android:visibility="visible" >
.....
<FrameLayout
android:id="#+id/fragment_host"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_above="#+id/mButtons"
android:layout_below="#+id/relLayout"
android:layout_marginBottom="20dp" />
Now view pager will come below 'relLayout' and above 'mButtons'

maybe your RelativeLayout is not full screen,so the FrameLayout will never aligned the bottom of the screen

You can try this,
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_content"
android:orientation="vertical">
<android.support.v4.view.ViewPager
android:layout_alignParentBottom="true"
android:id="#+id/tutorial_viewpager"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</RelativeLayout>

you can use like this also:
public class MyViewPager extends ViewPager {
public MyViewPager(Context context) {
super(context);
}
public MyViewPager(Context context, AttributeSet attrs) {
super(context, attrs);
}
#Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
// find the first child view
View view = getChildAt(0);
if (view != null) {
// measure the first child view with the specified measure spec
view.measure(widthMeasureSpec, heightMeasureSpec);
}
setMeasuredDimension(getMeasuredWidth(), measureHeight(heightMeasureSpec, view));
}
private int measureHeight(int measureSpec, View view) {
int result = 0;
int specMode = MeasureSpec.getMode(measureSpec);
int specSize = MeasureSpec.getSize(measureSpec);
if (specMode == MeasureSpec.EXACTLY) {
result = specSize;
} else {
// set the height from the base view if available
if (view != null) {
result = view.getMeasuredHeight();
}
if (specMode == MeasureSpec.AT_MOST) {
result = Math.min(result, specSize);
}
}
return result;
}
}
in xml:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_above="#+id/mButtons"
android:layout_below="#+id/relLayout"
android:background="#0000ff" >
<FrameLayout
android:id="#+id/fragment_host"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_marginBottom="20dp" />
</RelativeLayout>

GridView Expandable Height

I'm using ExpandableHeightGridView but I don't manage to calculate the correct height of the gridview, I use custom rows made ​​by an external layout, but it cuts several rows at the bottom,
here's the code:
public class ExpandableHeightGridView extends GridView {
boolean expanded = false;
public ExpandableHeightGridView(Context context) {
super(context);
}
public ExpandableHeightGridView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public ExpandableHeightGridView(Context context, AttributeSet attrs,
int defStyle) {
super(context, attrs, defStyle);
}
public boolean isExpanded() {
return expanded;
}
#Override
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
if (isExpanded()) {
int expandSpec = MeasureSpec.makeMeasureSpec(MEASURED_SIZE_MASK,
MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, expandSpec);
ViewGroup.LayoutParams params = getLayoutParams();
params.height = getMeasuredHeight();
} else {
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
}
public void setExpanded(boolean expanded) {
this.expanded = expanded;
}
}
