How to close chat head when it come in menu button in android?

Question

I am working with chat head and successfully implemented everything but I am not able to close it when it's approximately near or on menu button.

Edit source codes:

   public class CustomService extends Service {

    private static WindowManager windowManager;
    private static ImageView chatHead,closeView;
    private static Context context;

    @Override
    public IBinder onBind(Intent intent) {
        // Not used
        return null;
    }

    @Override
    public void onCreate() {
        super.onCreate();
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {

        windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);

        chatHead = new ImageView(this);
        chatHead.setImageResource(R.drawable.ic_launcher);

        final WindowManager.LayoutParams params = new WindowManager.LayoutParams(
                WindowManager.LayoutParams.WRAP_CONTENT,

        params.gravity = Gravity.CENTER | Gravity.CENTER;
        params.x = 0;
        params.y = 100;

        closeView = new ImageView(this);

How to close chat heads when my chat head come in approximately near or on menu button.

How to implement it. Please help me. Thanks

Answer 1

First of all, add a view and set it's gravity like this:

 params.gravity = Gravity.BOTTOM | Gravity.CENTER;         

and then add it to the windowManager after setting it's visibility to invisible:

closeView.setVisibility(View.INVISIBLE);
windowManager.addView(closeView, params);

You can show that view in ACTION_MOVE:

closeView.setVisibility(View.VISIBLE);

After that, do this in ACTION_UP to check if the views intercept:

                case MotionEvent.ACTION_UP:

                    Rect rect1 = new Rect(v.getLeft(), v.getTop(),
                            v.getRight(), v.getBottom());
                    v.getHitRect(rect1);

                    Rect rect2 = new Rect(closeView.getLeft(), closeView.getTop(),
                            closeView.getRight(), closeView.getBottom());
                    closeView.getHitRect(rect2);

                    if (Rect.intersects(rect1, rect2)) {

                        System.out.println("overlap");
                         // Here you can remove your view. 

                    } else {

                        System.out.println("no overlap");
                        // Here you can reset that view to it's initial position

                    }

OR

you can use another method:

private boolean isViewOverlapping(View firstView, View secondView) {
    int[] firstPosition = new int[2];
    int[] secondPosition = new int[2];

    firstView.measure(View.MeasureSpec.EXACTLY,
            View.MeasureSpec.EXACTLY);
    firstView.getLocationOnScreen(firstPosition);
    secondView.getLocationOnScreen(secondPosition);

    int r = firstView.getMeasuredWidth() + firstPosition[1];
    int l = secondPosition[1];

    System.out.println(r + " : r + l : " + l);

    return r == l && (r != 0 && l != 0);
}

and call it in ACTION_UP like this:

         boolean show = isViewOverlapping(chatHead, closeView);
                if (show == true) {
                    System.out.println("overlap");
                } else {
                    System.out.println("not overlap");

                }
