Android: make a scrollable custom view
- by Martyn
Hey,
I've rolled my own custom view and can draw to the screen alright, but what I'd really like to do is set the measuredHeigh of the screen to, say, 1000px and let the user scroll on the Y axis, but I'm having problems doing this. Can anyone help?
Here's some code:
public class TestScreen extends Activity {
CustomDrawableView mCustomDrawableView;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mCustomDrawableView = new CustomDrawableView(this);
setContentView(mCustomDrawableView);
}
}
and
public class CustomDrawableView extends View {
public CustomDrawableView(Context context) {
super(context);
setVerticalScrollBarEnabled(true);
setMinimumHeight(1000);
}
@Override
protected void onDraw(Canvas canvas) {
canvas.drawLine(...);
// more drawing
}
}
I've tried to override scrollTo, scrollBy, awakenScrollBars etc with a call to super but to no avail. Am I missing something silly, or am I making some fundamental mistake?
Thank you in advance,
Martyn
