Add float_view layout to WindowManager. In float_view layout, all of the controls are visible gone except butHead. butHead is overlay button. I want to show ovelay button click show other controls. I used with overlay button onTouchevent for overlay button click. My Error occur in input textbox control. Debug Device is Samsung Galaxy Note 2.

Update
In Samsung Note 2 Android 4.3, after texting the input textbox pressed enter key show google search app. What wrong my app with google search app.

(FloatBitchService.java)

public class FloatBitchService extends Service {
@Override
public void onCreate() {
    windowManager = (WindowManager)getSystemService(WINDOW_SERVICE);
    LayoutInflater inflater = LayoutInflater.from(this);        
    viewFloat = inflater.inflate(R.layout.float_view, null);
    butHead = (Button)viewFloat.findViewById(R.id.butHead);
