I found solution for this issue,It's working good.

public class MyFooterService extends Service{
View myview;
WindowManager wm;
FrameLayout wrapper;
public MyFooterService() {

}
 @Override
public void onCreate() {
    Log.d(TAG, "onCreate called");
    LayoutInflater li = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);
    wm = (WindowManager) getSystemService(WINDOW_SERVICE);
    final WindowManager.LayoutParams params = new WindowManager.LayoutParams(
            WindowManager.LayoutParams.MATCH_PARENT,
            90,  //height of ur layout
            WindowManager.LayoutParams.TYPE_PHONE,
            0,
            PixelFormat.TRANSLUCENT);

    params.gravity = Gravity.BOTTOM ;
    params.x = 0;
    params.y = 0;
   wrapper = new FrameLayout(this) {
        @Override
        public boolean dispatchKeyEvent(KeyEvent event) {
            if (event.getKeyCode()==KeyEvent.KEYCODE_BACK) {
              // handle the back button code;
             return true;
            }
          return super.dispatchKeyEvent(event);
        }
       //if pressed home key,
      public void onCloseSystemDialogs(String reason) {
            //The Code Want to Perform.
            System.out.println("System dialog " + reason);
            if (reason.equals("homekey")) {
                // handle home button 
            }
        }

     };
   myview = li.inflate(R.layout.my_footer, wrapper);   // here set into your own layout
   wm.addView(myview, params);

}
}
