Thanks for your responses. I think I have set the view in the content view (although I'm not entirely sure what that means...). But I don't think I made it "visible"... how do I do that?
This is what I have: public class TestDraw extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(new DemoView(this)); } private class DemoView extends View{ public DemoView(Context context){ super(context); } @Override protected void onDraw(Canvas canvas) { super.onDraw(canvas); canvas.drawColor(Color.WHITE); } public void drawTest() { // do something // i want onDraw to be called here // do something } } } On Mar 7, 7:59 am, MrSnowflake <mrsnowfl...@gmail.com> wrote: > onDraw() will only be called when the view is in the content view of > the Activity and visible! > > On 5 mrt, 20:25, mcmc <manni...@gmail.com> wrote: > > > I cannot get the onDraw function to be called.
