Question

I have created a class which extends View class.

public class SplashScreen extends View

and i use it by setting contentview

View splash = new SplashScreen(this);
setContentView(splash);

I need to set background image but I can’t use layout. I think I need to do canvas drawing but I don’t know how to do.

protected void onDraw(Canvas canvas) {
  ballBounds.set(ballX-ballRadius, ballY-ballRadius, ballX+ballRadius, ballY+ballRadius);
  paint.setColor(Color.LTGRAY);
  // canvas.drawImage(R.drawable.background_image); (Ps: I know there is no function such as drawImage)"
  canvas.drawOval(ballBounds, paint);}

Answer 1

If you want to just set the background you can do

public SplashScreen(Context context, AttributeSet attrs) {
    super(context, attrs);
    setBackgroundResource(R.drawable.background);
}
