How to Change color of Button in Android when Clicked?

One approach is to create an XML file like this in drawable, called whatever.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>

bgalt and bgnormare PNG images in drawable.

If you create the buttons programatically in your activity, you can set the background with:

final Button b = new Button (MyClass.this);
b.setBackgroundDrawable(getResources().getDrawable(R.drawable.whatever));

If you set your buttons' style with an XML, you would do something like:

<Button
  android:id="@+id/mybutton"
  android:background="@drawable/watever" />

And finally a link to a tutorial. Hope this helps.

Save this code in drawable folder with "bg_button.xml" and call "@drawable/bg_button" as background of button in your xml:

<?xml version="1.0" encoding="UTF-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true" >
        <shape>
            <solid
                android:color="#004F81" />
            <stroke
                android:width="1dp"
                android:color="#222222" />
            <corners
                android:radius="7dp" />
            <padding
                android:left="10dp"
                android:top="10dp"
                android:right="10dp"
                android:bottom="10dp" />
        </shape>
    </item>
    <item>
        <shape>
            <gradient
                android:startColor="#89cbee"
                android:endColor="#004F81"
                android:angle="270" />
            <stroke
                android:width="1dp"
                android:color="#4aa5d4" />
            <corners
                android:radius="7dp" />
            <padding
                android:left="10dp"
                android:top="10dp"
                android:right="10dp"
                android:bottom="10dp" />
        </shape>
    </item>
</selector>

Try This

    final Button button = (Button) findViewById(R.id.button_id);
    button.setOnTouchListener(new View.OnTouchListener() {

        @Override
        public boolean onTouch(View view, MotionEvent event) {
            if(event.getAction() == MotionEvent.ACTION_UP) {
                button.setBackgroundColor(Color.RED);
            } else if(event.getAction() == MotionEvent.ACTION_DOWN) {
                button.setBackgroundColor(Color.BLUE);
            }
            return false;
        }

    });
