問題タブ [android-tabbed-activity]

Androidスタジオでタブ付きビューを作成しましたが、問題が発生しました。ホームからカテゴリまたはお気に入りにスライドすると、テキストタイトルのホーム、カテゴリ、およびお気に入りの上にアイコンを配置します。このセクションにコメントすると、このセクションで問題が発生します。正常に動作しますが、このメソッドを呼び出すと、アプリを開いて別のクラスにスライドするとアイコンが1回だけ表示され、アイコンが消えます

そして、これは私がアイコンを呼び出した方法です

セクション全体をチェックして、どうすればそれができるか教えてください

Some other users and I are developing an Android application for the Stack Exchange chat network. We're adding a tutorial for each activity to explain the UI to the user. However, we've run into a bit of a road block.

The tutorial library wants a pointer to a view (be it a TextView, ImageView, whatever) in order to get the coordinates of the view in the display so it knows where to draw the drop shadows and stuff.

We have one activity which uses the standard "Tabbed Activity" from Android Studio, so we aren't using any custom toolbars.

The action bar looks like this:

And we want to grab a pointer to the TextView on each tab that holds the title of the tab.

So for example, we want to be able to access this Textview:

We haven't been real successful in finding anything on the internet about how to do this. It appears to be relatively easy if you're using a custom toolbar, but we aren't.

Digging in the AOSP source code, we found a potential way to do it, but the fields that we needed access to were either private or otherwise unaccessible from the main activity code.

So the question is, how can we grab a pointer to that TextView? Is it even possible?
