我在我的操作欄中有一個播放按鈕，我希望當我點擊播放按鈕，然後等待時間，它將連接到我的實時流，它會顯示循環進度條，當它與流連接時暫停和播放按鈕將appear.like下面的圖片如何在操作欄中放置圓形進度條？
這裏是我的代碼，我使用
action_bar_progress.xml
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
style="@android:style/Widget.ActionButton">
<ProgressBar
android:id="@+id/actionProgressBar"
android:layout_width="32dp"
android:layout_height="32dp"
android:visibility="visible"
android:layout_gravity="center" />
</FrameLayout>
menu.xml文件類
enter code here
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"

當我上播放按鈕，點擊它，然後顯示文本我已經寫在標題..我所需要的圓形進度條而不是文本還有一件事如何設置錯誤messages.for例如，如果流不可用意味着脫機，然後如何連接後幾分鐘將顯示消息給用戶的流不可用..
只是刪除** **所有權屬性，如果你只想顯示進度條 – sodhankit
@sodhankit我試了一下，然後就什麼都不顯示.. – Parv
