ok.. for anyone else out there.. I have devised (hacked?) a solution
to this... but it's a bit clumsy.
First I created a custom ImageView in which I added an
OnLayoutListener interface...
public class CustomImageView extends ImageView {
private final Rect bounds = new Rect();
private OnLayoutListener onLayoutListener;
public CustomImageView(Context context, AttributeSet attrs, int
defStyle) {
super(context, attrs, defStyle);
}
public CustomImageView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public CustomImageView(Context context) {
super(context);
}
@Override
protected void onLayout(boolean changed, int left, int top, int
right, int bottom) {
super.onLayout(changed, left, top, right, bottom);
if(onLayoutListener != null) {
if(changed) {
bounds.left = left;
bounds.top = top;
bounds.right = right;
bounds.bottom = bottom;
}
onLayoutListener.onLayout(bounds);
}
}
public final OnLayoutListener getOnLayoutListener() {
return onLayoutListener;
}
public final void setOnLayoutListener(OnLayoutListener
onLayoutListener) {
this.onLayoutListener = onLayoutListener;
}
public static interface OnLayoutListener {
public void onLayout(Rect bounds);
}
}
Then in my activity, I get a reference to the SlidingDrawer and the
CustomImageView
final CustomImageView sliderRefresh = (CustomImageView)
findViewById(R.id.slider_refresh);
final SlidingDrawer slider = (SlidingDrawer)
findViewById(R.id.slider);
// Create a rect to contain the coordinates of the image
final Rect imageRect = new Rect();
And add a listener to the image view
sliderRefresh.setOnLayoutListener(new
OnLayoutListener() {
@Override
public void onLayout(Rect bounds) {
sliderRefresh.getGlobalVisibleRect(imageRect);
}
});
Then reset the coordinates when the slider is opened/closed:
slider.setOnDrawerOpenListener(new
OnDrawerOpenListener() {
@Override
public void onDrawerOpened() {
sliderRefresh.getGlobalVisibleRect(imageRect);
}
});
slider.setOnDrawerCloseListener(new
OnDrawerCloseListener() {
@Override
public void onDrawerClosed() {
sliderRefresh.getGlobalVisibleRect(imageRect);
}
});
Finally in the slider touch listener, see if the touch event was
inside the image
slider.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent
event) {
if(event.getAction() ==
MotionEvent.ACTION_DOWN) {
if(imageRect.contains((int)event.getRawX(),
(int)event.getRawY())) {
// Handle the click here
return true;
}
}
return false;
}
});
Let's face it.. it's a hack.. but it works.
