How to catch RelativeLayout pressed state in Android? - android

I have Relative Layout with two TextViews inside.
How I can change text color TextViews, when RelativeLayout is pressed?
I tried used selectors, but Relative Layout don't support text color attribute.
Also a tried catch Relative Layout pressed state with OnFocus and OnTouch Listeners, but they don't working(OnFocusChangeListener) or working in one side(OnTouchListener).
The code:
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="243dp"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:background="#drawable/singup_button_selector"
android:clickable="true"
android:focusable="true"
android:gravity="center"
android:id="#+id/sungup"
android:textColor="#drawable/singup_button_text_selector"
android:focusableInTouchMode="true">
<TextView
android:id="#+id/singupTV1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:text="#string/singup"
android:textColor="#3c5775"/>
<TextView
android:id="#+id/singupTV2"
android:layout_width="300dp"
android:layout_height="wrap_content"
android:layout_below="#+id/singupTV1"
android:layout_marginTop="15dp"
android:gravity="center"
android:text="#string/singup_extended"
android:textColor="#506378"
android:textSize="15dp" />
</RelativeLayout>

You can set an onClickListener on the RelativeLayout, then in the onClick method, change the text colors in both TextViews in your code.

What worked for me was setting an OnTouchListener.
setOnTouchListener(new OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event)
{
if(event.getAction() == MotionEvent.ACTION_DOWN || event.getAction() == MotionEvent.ACTION_MOVE) {
// focus in
} else{
// focus out
}
return false;
}
});

how to detect tap anywhere on listview

I want an action to be performed every time I click on the screen . There is a list view inside Relative layout. When i set setOnCLickListener for relative layout alone when there is no listview inside it it is working but not with listview inside it. The items in the listview will be displayed only when I click on the screen each time . I tried setItemOnClickListener.Thats not working too.
android:layout_width="match_parent"
android:layout_height="match_parent"

android:clickable="true"
android:orientation="vertical" >
<RelativeLayout

android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:text="Janet"
android:textColor="#color/white"
android:textSize="20dp" />
</RelativeLayout>
The click is working only on the two text views not on the screen.
I want the click to work on the screen
for find out clicked on screen :
getWindow().getDecorView().setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View arg0, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
Toast.makeText(SecondActivity.this, "click on screen ", Toast.LENGTH_SHORT).show();
}
return false;
}
});
and for find out clicked on listView :
listView.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
Toast.makeText(SecondActivity.this, "Clicked On ListView", Toast.LENGTH_LONG).show();
return false;
}
});

Start outSide scroll after edittext scroll finished

I've tried every simple examples on stackoverflow but nothing can solve my problem. Here's my question
I have ScrollView in activity and I have scrollbars="vertical" option editText inside ScrollView.
I want to scroll outside scrollview's scroll after inside edittext scroll finish, like on top of the edittext scroll or bottom of the edittext scroll
I thought that it can be done with view catchs scroll lisetener but nothing worked.
Try the below sample code hope it works for you.
In XML
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#aa8822"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#aa8822"
android:orientation="vertical" >
<EditText
android:id="#+id/edt"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#android:color/white"
android:ems="10"
android:maxLines="3"
android:scrollbars="vertical"
android:textColor="#android:color/black"
android:textSize="20sp"
android:textStyle="bold" >
<requestFocus />
</EditText>
</LinearLayout>
</ScrollView>
Put some more view so the scroll view scroll works.
Now in your activity-
EditText edt = (EditText) findViewById(R.id.edt);
edt.setOnTouchListener(new OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
if (v.getId() == R.id.edt) {
v.getParent().requestDisallowInterceptTouchEvent(true);
switch (event.getAction() & MotionEvent.ACTION_MASK) {
case MotionEvent.ACTION_UP:
v.getParent().requestDisallowInterceptTouchEvent(false);
break;
}
}
return false;
}
});

scrollView.requestFocus() returns true, but it not works

All,I hava a scroll contains a editText.
Once I clicks the editText ,it gets focus and a SoftInput shows.
In my mind, if I clicks the blank space , the softinput hide, and editText lose the focus, and scrollview get focus.
So my code like this:
scrollView.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
//call twice, once down, once up
if (event.getAction() == MotionEvent.ACTION_DOWN) {
if (activity.getCurrentFocus() != null && activity.getCurrentFocus().getWindowToken() != null) {
inputManager.hideSoftInputFromWindow(activity.getCurrentFocus().getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
scrollView.requestFocus();
activity.getCurrentFocus();
}
}
return false;
}
});
ScrollView
android:focusable="true"
android:focusableInTouchMode="true"
android:id="#+id/scrollView"
android:layout_below="#+id/topBar"
android:layout_marginTop="20dp"
android:layout_width="match_parent"
android:layout_height="match_parent"
But after all, editText still focus(activity.getCurrentFocus() == editText), any advices?
Use LinearLayout instead of ScrollView. Or wrap EditText with LinearLayout below.
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/scrollView"
android:layout_gravity="center_horizontal" >
<LinearLayout
android:focusable="true"
android:focusableInTouchMode="true"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/linearLayout"
android:layout_gravity="center_horizontal" >
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:inputType="textEmailAddress"
android:ems="10"
android:id="#+id/editText" />
</LinearLayout>
</ScrollView>

EditText Scrollable with keyborad active

Well friend ..
I have a design so:
The main Scroll is very necessary when appear the keyboard... If i dont make that, the button can't see...
The problem is when i try move inside the Edittext with the keyboard active...
I tried this:
android:scrollbars="vertical"
and this:
setMovementMethod(new ScrollingMovementMethod());
but not solve this yet
Anyone help me?
grax advance!
Check this without using scroll bar:
add permission in menifest file for corresponding activity.
android:windowSoftInputMode="adjustPan"
Please try this:
Your layout should be similar to example:
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/scrollView1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<EditText
android:id="#+id/edittext"
android:layout_width="200dp"
android:layout_height="500dp"
android:text="some long text"
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button" />
</LinearLayout>
</ScrollView>
and in your java try this:
EditText edit = (EditText)findViewById(R.id.edittext);
edit.setOnTouchListener(new OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
if (v.getId() == R.id.edittext) {
v.getParent().requestDisallowInterceptTouchEvent(true);
switch (event.getAction() & MotionEvent.ACTION_MASK) {
case MotionEvent.ACTION_UP:
v.getParent().requestDisallowInterceptTouchEvent(false);
break;
}
}
return false;
}
});

How can i check that the LinearLayout is clicked or not

This is my xml file and as you can see it is nested many times by Linear layout.
What i want to acheive is when I click on the area of llOptionA(First
Linear Layout) i will get notified by a toast.
I have also put a toast on llOptionA.setonclickListener()
But when i click on the text it does nothing.
then I also set onclicklisteners on each of them giving me different toasts -> svTest ,layout_inner ,tvOptionA. and also i clicked everywhere to see which part is showing which toast.
<LinearLayout
android:id="#+id/llOptionA"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:background="#ff00ff"
android:paddingLeft="30dp"
android:paddingRight="30dp"
android:paddingTop="5dp" >
<HorizontalScrollView
android:id="#+id/svTest"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<LinearLayout
android:id="#+id/layout_inner"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical" >
<TextView
android:id="#+id/tvOptionA"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:maxLines="1"
android:text="A - Option A "
android:textAppearance="?android:attr/textAppearanceMedium"
android:textColor="#ffffff"
android:textStyle="bold" />
</LinearLayout>
</HorizontalScrollView>
</LinearLayout>
First a LinearLayout does not listen for click events by default even when you set an OnClickListener. You also need to add this attribute to your LinearLayout llOptionA:
android:clickable="true"
Second a click starts at the highest level, TextView tvOptionA, and works it's way down until a View consumes this event. So before it reaches llOptionA your HorizontalScrollView intercepts the click in it's default OnTouchListener and doesn't pass it down to your llOptionA... You can listener for a click event with an OnTouchListener in your HorizontalScrollView to call the appropriate method.
Third perhaps this is a simplified layout, but the LinearLayout layout_inner only has one child and therefor is not necessary, you can simply use this:
<LinearLayout ...>
<HorizontalScrollView ...>
<TextView .../>
</HorizontalScrollView>
</LinearLayout>
Of course llOptionA only has one child so you could simplify it more:
<HorizontalScrollView ...>
<TextView .../>
</HorizontalScrollView>
Addition from comments
Here is how to put it all together:
public class Example extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
LinearLayout linearLayout = (LinearLayout) findViewById(R.id.llOptionA);
linearLayout.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
toast();
}
});
HorizontalScrollView hsv = (HorizontalScrollView) findViewById(R.id.svTest);
hsv.setOnTouchListener(new OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
if(event.getAction() == MotionEvent.ACTION_UP)
toast();
return false;
}
});
}
public void toast() {
Toast.makeText(this, "Click", Toast.LENGTH_SHORT).show();
}
}
