Floating View for Android app - Facebook ChatHeads Notification system This is a demo of how works Facebook ChatHeads.
Basiclay all you need to do is to create a service (background running) with image View like this :
windowManager = (WindowManager) getSystemService(WINDOW_SERVICE); chatHead = new ImageView(this); chatHead.setImageResource(R.drawable.floating2); final WindowManager.LayoutParams params = new WindowManager.LayoutParams( WindowManager.LayoutParams.WRAP_CONTENT, WindowManager.LayoutParams.WRAP_CONTENT, WindowManager.LayoutParams.TYPE_PHONE, WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE, PixelFormat.TRANSLUCENT); params.gravity = Gravity.TOP | Gravity.LEFT; params.x = 0; params.y = 100; Then start your service :
startService(new Intent(MainActivity.this, ServiceFloating.class)); If you wanna have a floating window, you can use PopupWindow :
LayoutInflater layoutInflater = (LayoutInflater)getBaseContext().getSystemService(LAYOUT_INFLATER_SERVICE); View popupView = layoutInflater.inflate(R.layout.popup, null); pwindo = new PopupWindow(popupView, LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT); if(_enable == true) { pwindo.showAsDropDown(chatHead, 50, -30);
