MainActivity.java

                Toast.makeText(getBaseContext(), "Playing...", Toast.LENGTH_LONG).show();

            }
            else
            {
                mnuPlay.setVisible(false);
                mnuPause.setVisible(false);
                mnuStop.setVisible(false);

            }

            break;

        case R.id.actionPause:
            //bPaused=true;
            if (mediaPlayer.isPlaying())
            {
                mediaPlayer.pause();
                bPaused=true;
                mnuPause.setVisible(false);
                mnuPlay.setVisible(true);
                mnuStop.setVisible(true);
                mnuProgressBar.setVisible(false);
                Toast.makeText(MainActivity.this, "Paused!", Toast.LENGTH_SHORT).show();
            }
            break;

        case R.id.actionStop:
            if (mediaPlayer.isPlaying() || bPaused)
            {
                Toast.makeText(this, "Stopping...", Toast.LENGTH_LONG).show();

                mediaPlayer.stop();
                mediaPlayer.release();
                bConnected = false;
                bPaused=false;
                bShouldPlay = false;
                mnuPlay.setVisible(true);
                mnuPause.setVisible(false);
                mnuStop.setVisible(false);
                mnuProgressBar.setVisible(false);

                Toast.makeText(this, "Stopped!", Toast.LENGTH_LONG).show();

            }
            break;
        default:
            break;
    }
    return super.onOptionsItemSelected(item);
}

当我点击播放按钮时，它会显示我在标题中写的文本。我需要圆形进度条而不是那个文本，还有一件事如何设置错误 messages.for 例如，如果流不可用意味着离线然后如何在连接几分钟后向用户显示消息流不可用..

您可以使用工具栏内的进度条来完成。 Toolbar 只是一个 ViewGroup:

 <android.support.v7.widget.Toolbar
    android:id="@+id/toolbar_main"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:background="#2196F3"
    app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fitsSystemWindows="true"
        android:orientation="horizontal">

        <LinearLayout
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight=".70"
            android:gravity="center"
            android:orientation="horizontal"
            android:text="left">

            <TextView
                android:id="@+id/toolbar_title"
                style="@style/TextAppearance.AppCompat.Widget.ActionBar.Title"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="center"
                android:text="Tital"
                android:textColor="@color/white"
                android:textSize="20dp"
                android:textStyle="bold" />
        </LinearLayout>

        <LinearLayout
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:layout_weight=".30"
            android:text="right">

            <ProgressBar
                android:id="@+id/actionProgressBar"
                android:layout_width="32dp"
                android:layout_height="32dp"
                android:layout_gravity="center"
                android:visibility="visible" />
        </LinearLayout>
    </LinearLayout>
</android.support.v7.widget.Toolbar>

改变

android:actionLayout="@layout/action_bar_progress"

到

app:actionLayout="@layout/action_bar_progress"
