Here is the code snippet of the C'tor:
public class CanvasLayout extends FrameLayout
{
public CanvasView canvasView;
public CanvasLayout(Activity context)
{
super(context);
// setFocusableInTouchMode(true);
canvasView = new CanvasView(context);
canvasView.setFocusableInTouchMode(true);
addView(canvasView);
editControl = new MyEditText(context);
editControl.setBackgroundColor(Color.GREEN);
editControl.setVisibility(EditText.GONE);
editControl.setPadding(0, 0, 0, 0);
editControl.setFocusableInTouchMode(true);
FrameLayout.LayoutParams params = new
FrameLayout.LayoutParams(0, 0,Gravity.TOP|Gravity.LEFT);
params.setMargins(0, 0, 0, 0);
editControl.setLayoutParams(params);
// addView(editControl);
context.addContentView(editControl, params);
}
Basically i didn't have to create my own layout, it allowed later on
to use it's onSizeChnaged but basically i don't have to.
