Question

Can I find out the width of screen programmatically in android app? I need to paint canvas but its width should be almost like screen and I could not set match_parent in java part program.

Answer 1

You can get default Display instance and then read width/height from it:

int width = getWindowManager().getDefaultDisplay().getWidth();
int height = getWindowManager().getDefaultDisplay().getHeight();
