Hai refer this,

        boolean check=false;
        Button backward_img;        Button backward_img1;
         backward_img = (Button) findViewById(R.id.bars_footer_backward);
         backward_img1 = (Button) findViewById(R.id.bars_footer_backward1);
    backward_img.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View arg0) {
                              check=true;
                    backward_img.setBackgroundColor(Color.BLUE);
                }

            });

        if(check== true)
{
            backward_img1.setBackgroundColor(Color.RED);
            backward_img.setBackgroundColor(Color.BLUE);
}

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"&gt; 
      <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" />

I'll try to find you a link to a tutorial. Hope this helps.
