LinearLayout.LayoutParams lp = new LinearLayout. The proof of concept is here - Smart Taskbar (on AppBrain) and here V1.4.0 Sidebar style SWKey - Button savior (on xda-developers) I have been successful and have a running service now. Now this layout need to be of very small size lying somewhere in the corner, So that it doesn’t consumes you click events when you are on external applications. It uses the Matchbox window manager and the GTK-based Hildon as its GUI and application framework. 311 I'm trying to create an always-op-top button/clickable-image which stays on top of all the windows all the time. Now let’s get into implementation, you will be needing one Service which will running all the time in you mobile system and one Layout which has the sole responsibility to listening to the touch events provided by View.OnTouchListener. Some people online said how they get errors. It uses for the windows however and it says that it's deprecated on API level 26. But calling this method requires applying for the permission On. I have an application which shows floating overlay windows and it works fine. If set the type to TYPEPHONE, then this view can floating above the window of most apps. ![]() Touch will get invoked every time you perform any gesture or event on touch screen while click event very much particular to just simple click event and it is followed by touch event when certain conditions are met, for example if the user touch and doesn’t hold the touch for not more than 300ms. Android overlay window on API 26+, vs TYPEPHONE. windowManager (WindowManager) ctx.getApplicationContext().getSystemService(WINDOWSERVICE) WindowManager.LayoutParams params new WindowManager.LayoutParams( 300,300,PixelFormat.TRANSPARENT) avity Gravity.TOP Gravity.LEFT params.x 0 params. Because it is the service which can runs all the time without UI.īefore going into implementation you should know that there is difference between touch and click event. There is no conventional way of using some apis to detect the touch, you will be needing a service which will running all the time even if your application dies. if ( detect touch events happening anywhere within the android system or its applications can only be possible if there is some service providing that information. Since OV1 had higher priority, it always stayed on top of OV2, so it wasn't affected by FLAGDIMBEHIND, and the user could. I had the exactly same issue in service class(before and after Marshmallow). The solution I found was setting layout params differently for each overlay: OV1 gets: params.type Whereas OV2 gets: params.type.
