I'm not tested below code. but i think this will helpful to you.

private Drawable defaultDrawableA;
private Drawable defaultDrawableB;
private Button buttonA , buttonB;


buttonA = (Button) findViewById(R.id.buttonA);
buttonB= (Button) findViewById(R.id.buttonB);
    buttonA .setOnClickListener(this);
    buttonB.setOnClickListener(this);


@Override
public void onClick(View v) {
    if (v == buttonA)

if(defaultDrawableA== null)
{
    defaultDrawableA=buttonA.getDrawable();
    buttonA.setBackgroundColor(Color.BLUE);
}
else
{
    buttonA.setBackgroundDrawable(defaultDrawableA);
    defaultDrawableA=null;
}
    else if (v == buttonB)

if(defaultDrawableB == null)
{
    defaultDrawableB=buttonB.getDrawable();
    buttonB.setBackgroundColor(Color.RED);
}
else
{
    buttonB.setBackgroundDrawable(defaultDrawableB);
    defaultDrawableB=null;
}

    return;
}

Try this...

button_bg.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
    android:drawable="@color/button_pressed"/> <!-- pressed -->
<item android:drawable="@color/button_default"/> <!-- default -->

activity_main.xml

 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity">

<Button
    android:id="@+id/button1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/button_bg"
    android:text="Click Me"
    android:textColor="#fff" />

Answer 4

Try this:

final Button buttonA = (Button) findViewById(R.id.ButtonA);
final Button buttonB = (Button) findViewById(R.id.ButtonB);

buttonA.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
buttonB.setBackgroundColor(Color.CYAN);
}
});

buttonB.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
buttonA.setBackgroundColor(Color.RED);
}
});

or

make selector.xml in drawables folder and copy code below in it:

<?xml version="1.0" encoding="utf-8"?> 
<selector xmlns:android="http://schemas.android.com/apk/res/android"> 
  <item android:state_focused="true" android:state_pressed="true" 
    android:drawable="@drawable/focused_pressed" /> 
  <item android:state_focused="false" android:state_pressed="true" 
    android:drawable="@drawable/pressed" /> 
  <item android:drawable="@drawable/normal" /> 
</selector>

copy this code for buttonA in your layout

<Button
    android:id="@+id/buttonA"
    style="@drawable/test"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentRight="true"
    android:layout_alignParentTop="true"
    android:text="Button A" />

Answer 5

buttoncolor.xml

<?xml version="1.0" encoding="utf-8"?> 
  <selector xmlns:android="http://schemas.android.com/apk/res/android"> 
      <item android:state_focused="true" android:state_pressed="true" 
            android:drawable="@drawable/bgalt" /> 
      <item android:state_focused="false" android:state_pressed="true" 
            android:drawable="@drawable/bgalt" /> 
      <item android:drawable="@drawable/bgnorm" /> 
  </selector>

Now use like below:

b1 = (Button) findViewById(R.id.b1);
b1.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View arg0) {
         b2.setBackgroundDrawable(getResources().getDrawable(R.drawable.whatever));
    }
});

b2 = (Button) findViewById(R.id.b2);
b2.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View arg0) {
         b1.setBackgroundDrawable(getResources().getDrawable(R.drawable.whatever));
    }
});

Easiest way

just change color whatever you want

button_design.xml

<?xml version="1.0" encoding="utf-8"?>

<item android:state_pressed="true">
    <shape android:shape="rectangle">
        <solid android:color="@color/colorPurple"></solid>
        <corners android:radius="100dp" />
    </shape>
</item>

<item>
    <shape android:shape="rectangle">
        <gradient android:endColor="@color/colorPurple" android:startColor="@color/colorBlue" />
        <corners android:radius="100dp" />
    </shape>
</item>
