Hi,
I am trying to write an app which has an ImageView and the app allows
to perform panning on the image. I also want to register context menu
with this ImageView so that on long press Context menu comes up. I
tried playing around with the onTouch method, but could not get it
working.
On long press, i do see context menu. But, while panning also the
context menu comes up. I want that context menu is displayed only when
long press is performed and not while panning. If I return true from
the down event, the context menu fails to come up.
Please find the snippet of the code below for the reference.
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ImageView image = (ImageView) findViewById(R.id.image_id);
image.setOnTouchListener(this);
registerForContextMenu(image);
}
public boolean onTouch(View view, MotionEvent event)
{
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
mXPos = event.getRawX();
mYPos = event.getRawY();
return false;
case MotionEvent.ACTION_MOVE:
float newXPos = event.getRawX();
float newYPos = event.getRawY();
view.scrollBy((int)(mXPos - newXPos), (int)(mYPos -
newYPos));
mXPos = newXPos;
mYPos = newYPos;
return true;
case MotionEvent.ACTION_UP:
return false;
}
return false;
}
public void onCreateContextMenu(ContextMenu menu, View v,
ContextMenuInfo menuInfo) {
menu.add(Menu.NONE, 0, Menu.NONE, "Item1");
menu.add(Menu.NONE, 1, Menu.NONE, "Item2");
}
private float mXPos, mYPos;
Thanks in Advance.
