Hi Kostya,
I have a GalleryView in my ViewStub and I dynamically add images to
the Gallery. I would like to control from a menu option, the
visibility of the complete ViewStub view. So basically, when the
ViewStub is up displaying the gallery and I press the menu option, the
whole view gets hidden but the content (i.e. Gallery items) remain in
the stub. On pressing menu option again, the whole view is displayed
again with the gallery items selected earlier.
I don't know what you mean by replacing the stub with include and
toggle its contents' visibility. Could you elaborate a little more?
Thanks,
Abhi

Inflating a view stub has two important properties:
1) It's irreversible: once inflated, the stub's content is always there
2) The stub's content replaces the stub.
Sounds like you need to replace the stub with include and toggle its
contents' visibility as needed.

I keep getting NullPointerException trying to deflate or make
invisible the ViewStub from my UI. I just wanted to be sure I am doing
it right.
I am inflating my ViewStub in onItemLongClick method of GalleryView by
doing the following:
@Override
public boolean onItemLongClick(AdapterView? arg0, View
viu, int arg2,
long arg3) {
Toast.makeText(GalleryView.this, New item added to
Favorites, Toast.LENGTH_SHORT).show();
favsCount++;
//checking to see if ViewStub is already inflated or
not
if(!stubvis){
stub = (ViewStub) findViewById(R.id.stub1);
stub.inflate();
stubvis = true;
trayUP = true;
}
return true;
}
});
and then in onPrepareOptionsMenu() I am adding the menu item based on
the visibility of ViewStub. If inflated and visible, I create a menu
item to hide it, otherwise, a menu item to show/make visible.
@Override
public boolean onPrepareOptionsMenu(Menu menu) {
menu.clear();
if(trayUP) {
menu.add(0, HIDETRAY, 0, Hide Favorites Tray);
} else {
menu.add(0, SHOWTRAY, 0, Show Favorites Tray);
}
return super.onPrepareOptionsMenu(menu);
}
Next, in onOptionsItemSelected(), I am writing the two cases based on
the menu item selection. Case 1 when the tray is not visible, so I
make it visible. Case 2 when it is visible, so I hide it by doing the
following:
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case HIDETRAY:
Log.v(TAG, Hiding Favs Tray);
findViewById(R.id.stub1).setVisibility(View.GONE);
trayUP = false;
case SHOWTRAY:
Log.v(TAG, Showing Favs Tray);
findViewById(R.id.stub1).setVisibility(View.VISIBLE);
trayUP = true;
}
return true;
}
I know I am making a silly mistake somewhere. And my mind is too
saturated to think straight at the moment. Need help :(
Thanks,
Ab
