What it is
A short Android tutorial from the mybringback channel (episode 1.28) that introduces SurfaceView. It shows how to set up a separate thread for graphics rather than drawing on the main UI thread, as a basic setup before doing actual drawing.

You can only draw in the main UI thread. You should use SurfaceView, since it was made specifically to support drawing from secondary threads. One of the purposes of this class is to provide a surface in which a secondary thread can render into the screen. If you are going to use it this way, you need to be aware of some threading semantics. source [LINK] See also this video: Learn Android Tutorial 1.28- Introduction to the SurfaceView [this video]

You can't draw images in a SurfaceView from a layout file. You need to get a reference of the SurfaceView from your activity like so: SurfaceView sv = (SurfaceView) findViewById(R.id.hero3); Additionally, you can't modify the SurfaceView specific properties of the SurfaceView from layouts. If you check out the documentation [LINK] , the only XML attributes that the SurfaceView has are the ones provided by View. You can modify the SurfaceView specific properties from code using the reference above. For example: sv.setZOrderOnTop(true); Drawing onto a SurfaceView is a little more complex, and you should weigh the benefits of using the SurfaceView instead of a regular View [LINK] . if you decid

You could find how to do so over here, however as @vizier I'd recommend you to use a game engine which will handle all that for you [this video]

You need to use the SurfaceView widget that is available in the XML But if you want the image to be move-able around all the screen you could use SurfaceView Check this Youtube video, It's very informative (watch all the SurfaceView playlist to benefit) [this video]
