Android : Get view Reference to a Menu Item
I plan to use quick actions UI pattern in my application. Android Quick Actions UI Pattern . The quick action window needs a pivot view to stick to.
quickAction.show(View pivotView);
I intend to use quick action for the menu Item, I can get access to the item that is clicked. But the problem is i need to reference a view from the menu item so that i can pass it to the quick action.
How can i get reference to a view in the menuItem that is selected.
Solution 1:
You can achieve this by providing your menu item with an actionViewClass property in xml and then you will be able to get the pivot view u wanted. The code would be something like this
<item
android:id="@+id/menu_find"
android:showAsAction="ifRoom"
android:actionViewClass="android.widget.ImageButton"
/>
In your OnCreateOptionsMenu do this
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
getMenuInflater().inflate(R.menu.menu_search, menu);
locButton = (ImageButton) menu.findItem(R.id.menu_find).getActionView();
locButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
createPopup();
mQuickAction.show(v);
}
});
return true;
}
Solution 2:
Old question, but I ran into some issues with the actionViewClass
attribute. For anyone who runs into this later...
Calling findViewById(R.id.mnu_item)
in onOptionsItemSelected
will return a View
anchor.
QuickActions
on the MenuItems
aren't good design, but I found that they are the simplest way to implement submenus with custom backgrounds.
Solution 3:
Inorder to get reference Views of menu items we need to do this,
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.section, menu);
new Handler().post(new Runnable() {
@Override
public void run() {
final View menuItemView = findViewById(R.id.action_preview);
// SOME OF YOUR TASK AFTER GETTING VIEW REFERENCE
}
});
return true;
}

An update for anyone that want to find the menu view item for other reasons (like I wanted).
If you have access to and use AppCompat's Toolbar there is a way. It's not the most efficient way, but it's the easiest way I've found to access the menu item's view.
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
Toolbar toolbar = (Toolbar) view.findViewById(R.id.toolbar);
// Find Menu
for (int toolbarChildIndex = 0; toolbarChildIndex < toolbar.getChildCount(); toolbarChildIndex++) {
View view = toolbar.getChildAt(toolbarChildIndex);
// Found Menu
if (view instanceof ActionMenuView) {
ActionMenuView menuView = (ActionMenuView) view;
// All menu items
for (int menuChildIndex = 0; menuChildIndex < menuView.getChildCount(); menuChildIndex++) {
ActionMenuItemView itemView = (ActionMenuItemView) menuView.getChildAt(menuChildIndex);
// Do something to itemView...
}
}
}
}
