OnDraw of SurfaceView calling period

Question

I am wondering what is the period of calling for the method OnDraw of a SurfaceView. Does it depends on the device?

For example, Is this method call 32, 24 or 16 times per second?

thank you all!

Answer 1

Android will call onDraw() method of a view class ( e.g SurfaceView) each time the view needs to be refreshed. The number of times a view gets refreshed depends on the Refresh Rate of the device.

You can use getRefreshRate() to get the refresh rate of the display in frames per second.

Display display = ((WindowManager) getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();
int refreshRate = display.getRefreshRate();
