Android Button color changing on onClick?

Question

I am facing a problem .

I have two Button object.

ButtonA ButtonB

Requirement:-

When ever I press ButtonA the color of button should be changed and it should remain same until I clicked on ButtonB.

After click on ButtonB same thing should be working i.e for ButtonA

if (v == btn)
{
    btn.setBackground(mActivity.getResources().getDrawable(R.drawable.button_color_chnager));
}

XML:

<item android:state_focused="true" android:state_pressed="true" 
            android:drawable="@drawable/ic_launcher" /> 

Answer 1

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));
    }
});
