Find position of MenuItem dynamically

Question

I have a menu with all items' showAsAction set to ifRoom. Now I want to get the exact position (x,y) of the center of any of these menu items.

I first thought of getting this information from the underlying views, but I don't know how to reliably access the view of a specific menu item.

In onCreateOptionsMenu:

MenuItem someItem = menu.findItem(R.id.some_action); // someItem.getX(); // someItem.getY();

I'd expect these coordinates to be relative to the application's Toolbar. In this case I also need access to someItem.get{Width,Height}() to calculate the center coordinates.

An example menu:

<menu xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto"> <item android:id="@+id/action_search" android:title="@string/action_search" android:icon="@drawable/ic_search" app:actionViewClass="android.support.v7.widget.SearchView" app:showAsAction="ifRoom|collapseActionView" /> <item android:id="@+id/action_example" android:title="@string/action_example" android:icon="@drawable/ic_example" app:showAsAction="ifRoom" /> </menu>

The solution is to use the underlying activity to find the instanciated view.

View menuItemView = getActivity().findViewById(R.id.action_search);

Then the position can be extracted relative to the toolbar by using View.getLocationInWindow(intArr), which returns (x,y) relative to the view's window.

int[] itemWindowLocation = new int[2]; menuItemView.getLocationInWindow(itemWindowLocation); int[] toolbarWindowLocation = new int[2]; toolbar.getLocationInWindow(toolbarWindowLocation); int itemX = itemWindowLocation[0] - toolbarWindowLocation[0]; int itemY = itemWindowLocation[1] - toolbarWindowLocation[1]; int centerX = itemX + menuItemView.getWidth() / 2; int centerY = itemY + menuItemView.getHeight() / 2;
