在Android 5.0棒棒糖中制作带有徽章/计数的工具栏通知图标

Question

How to add badge/count to notification in android 5.0 toolbar. I tried below code and it is working on 4.4. But when i use toolbar, it gives me NPE on countView.

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.dashboad, menu);

    final View menuWork = menu.findItem(R.id.action_work).getActionView();
    countView = (TextView) menuWork.findViewById(R.id.actionbar_notification_textview);

    ImageButton notifyLayout = (ImageButton) menuWork.findViewById(R.id.img);
    menuWork.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

        }
    });

    return true;
}

xml code for menu item

<item
    android:id="@+id/action_work"
    android:actionLayout="@layout/notification_alert"
    android:icon="@android:drawable/ic_popup_reminder"
    android:orderInCategory="100"
    android:title="Job"
    app:showAsAction="always" />

Answer 1

Just replace:

android:actionLayout="@layout/notification_alert"

With:

 app:actionLayout="@layout/notification_alert"
