Is this a bug?
Android can't recognize the difference between
the motion of long touch action and the motion of move action.
It is different between the long touch action and the move action,
isn't it?
So, I modified my code without using onInterceptTouchEvent.
/*------ ZoomMapView.java -------*/
public class ZoomMapView extends MapView implements
OnLongClickListener {
private static final int FILL = ViewGroup.LayoutParams.FILL_PARENT;
private boolean moving;
private ZoomControls zoomControls;
public ZoomMapView(Context context, String apiKey) {
super(context, apiKey);
// long click settings.
moving = false;
setClickable(true);
setLongClickable(true);
setOnLongClickListener(this);
// ZoomControls settings.
zoomControls = (ZoomControls) getZoomControls();
zoomControls.setLayoutParams(new ViewGroup.LayoutParams(FILL,
FILL));
zoomControls.setGravity(Gravity.BOTTOM +
Gravity.CENTER_HORIZONTAL);
addView(zoomControls);
}
// OnLongClickListener interface method
public boolean onLongClick(View arg0) {
if (!moving) {
displayZoomControls(true);
}
return true;
}
@Override
public boolean onTouchEvent(MotionEvent me) {
switch (me.getAction()) {
case MotionEvent.ACTION_MOVE:
moving = true;
break;
case MotionEvent.ACTION_UP:
if (moving) {
zoomControls.hide();
}
moving = false;
break;
}
return super.onTouchEvent(me);
}
}
This code doesn't trigger another behavior like onInterceptTouchEvent.
What do you think about my code?
