我试过像这样的Action Bar

Screenshot of my action Bar

我希望当我点击Actionbar的项目时它会打印一个Toast但是它没有尝试过很多次。

我创建了2个自定义布局，一个用于通知自定义项目，另一个用于任务自定义项目。

custom_action_notification_layout.xml 

 <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    style="?attr/actionButtonStyle"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:clipToPadding="false"
    android:focusable="true">

    <ImageView
        android:layout_width="40dp"
        android:layout_height="40dp"
        android:layout_gravity="center"
        android:src="@drawable/noti"/>

    <TextView
        android:id="@+id/cart_badge"
        android:layout_width="20dp"
        android:layout_height="20dp"
        android:layout_gravity="right|end|top"
        android:layout_marginTop="3dp"
        android:layout_marginLeft="15dp"
        android:background="@drawable/badge_circle"
        android:gravity="center"
        android:padding="3dp"
        android:textColor="@android:color/white"
        android:text="0"
        android:textSize="10sp"/>

</RelativeLayout>

custom_action_task_layout.xml 

    <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    style="?attr/actionButtonStyle"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:clipToPadding="false"
    android:focusable="true">

    <ImageView
        android:layout_width="40dp"
        android:layout_height="40dp"
        android:layout_gravity="center"
        android:src="@drawable/task"
        android:id="@+id/imageView5" />

    <TextView
        android:id="@+id/cart_badge1"
        android:layout_width="20dp"
        android:layout_height="20dp"
        android:layout_marginLeft="15dp"
        android:layout_gravity="right|end|top"
        android:background="@drawable/badge_circle"
        android:gravity="center"
        android:padding="3dp"
        android:textColor="@android:color/white"
        android:text="0"
        android:textSize="10sp"
        android:layout_alignTop="@+id/imageView5"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true" />

</RelativeLayout>

navigation.menu 

<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:apps="http://schemas.android.com/tools">

<item
    android:id="@+id/action_refresh"
    android:icon="@drawable/noti"
    app:showAsAction="always"
    android:actionLayout="@layout/custom_action_notification_layout"
    android:title="Refresh"/>
<item
    android:id="@+id/action_task"
    android:orderInCategory="100"
    android:actionLayout="@layout/custom_action_task_layout"
    android:title="Task"
    android:icon="@drawable/task"
    app:showAsAction="always" /></menu>

现在在我的navigationdrawer.class中，我把这个代码放在了创建OptionsMenu（）上，获取了通知和任务项的ActionView以及将OnClick侦听器设置为那些ActionView。

navigation.class 

@Override
    public boolean onCreateOptionsMenu(final Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.navigation, menu);
        // Notification
        final MenuItem itemNotification = menu.findItem(R.id.action_refresh);
        MenuItemCompat.setActionView(itemNotification, R.layout.custom_action_notification_layout);
        View actionViewNotification = MenuItemCompat.getActionView(itemNotification);

      //  RelativeLayout notifCount = (RelativeLayout) MenuItemCompat.getActionView(itemNotification);
        actionViewNotification.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                onOptionsItemSelected(itemNotification);
            }
        });
        final MenuItem itemNotification1 = menu.findItem(R.id.action_task);
        MenuItemCompat.setActionView(itemNotification1, R.layout.custom_action_task_layout);
        View actionViewNotification1 = MenuItemCompat.getActionView(itemNotification1);

    //   RelativeLayout notifCount1 = (RelativeLayout) MenuItemCompat.getActionView(itemNotification1);
        actionViewNotification1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                onOptionsItemSelected(itemNotification1);
            }
        });

现在终于在onOptionsItemSelected（）中代码就像

public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case R.id.action_refresh: {
            // Do something
            Toast toast = Toast.makeText(this, "Notification clicked", Toast.LENGTH_LONG);
            toast.setGravity(Gravity.CENTER, 0, 0);
            toast.show();
            return true;
        }
        case R.id.action_task: {
            // Do something
            Toast toast = Toast.makeText(this, "Task clicked", Toast.LENGTH_SHORT);
            toast.setGravity(Gravity.CENTER, 0, 0);
            toast.show();
            return true;
        }
    }

在许多方面尝试过，但根本没有工作，请从这里帮忙..

答案 0 :(得分：1)

1。创建两个custom layout，一个用于Notification自定义item，另一个用于Task自定义item。

<强> custom_action_notification_layout.xml 

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
    style="?attr/actionButtonStyle"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:clipToPadding="false"
    android:focusable="true">

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:src="@drawable/icon_notification"/>

    <TextView
        android:id="@+id/cart_badge"
        android:layout_width="20dp"
        android:layout_height="20dp"
        android:layout_gravity="right|end|top"
        android:layout_marginEnd="-5dp"
        android:layout_marginRight="-5dp"
        android:layout_marginTop="3dp"
        android:background="@drawable/badge_background"
        android:gravity="center"
        android:padding="3dp"
        android:textColor="@android:color/white"
        android:text="0"
        android:textSize="10sp"/>

</FrameLayout>

<强> custom_action_task_layout.xml 

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
    style="?attr/actionButtonStyle"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:clipToPadding="false"
    android:focusable="true">

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:src="@drawable/icon_task"/>

    <TextView
        android:id="@+id/cart_badge"
        android:layout_width="20dp"
        android:layout_height="20dp"
        android:layout_gravity="right|end|top"
        android:layout_marginEnd="-5dp"
        android:layout_marginRight="-5dp"
        android:layout_marginTop="3dp"
        android:background="@drawable/badge_background"
        android:gravity="center"
        android:padding="3dp"
        android:textColor="@android:color/white"
        android:text="0"
        android:textSize="10sp"/>

</FrameLayout>

2。创建包含menu和Notification项的Task XML。使用属性app:actionLayout将custom layout设置为每个item。

<强> custom_menu.xml 

<menu
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto" >

    <item
        android:id="@+id/action_notification"
        android:icon="@drawable/icon_notification"
        android:title="Notification"
        app:actionLayout="@layout/custom_action_notification_layout"
        app:showAsAction="always"/>

    <item
        android:id="@+id/action_task"
        android:icon="@drawable/icon_task"
        android:title="Task"
        app:actionLayout="@layout/custom_action_task_layout"
        app:showAsAction="always"/>

</menu>

3。在您的活动onCreateOptionsMenu()中，获取ActionView个Notification项和Task项，并将OnClick个听众设置为ActionView。

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

    // Notification
    final MenuItem itemNotification = menu.findItem(R.id.action_notification);
    View actionViewNotification = MenuItemCompat.getActionView(itemNotification);
    actionViewNotification.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            onOptionsItemSelected(itemNotification);
        }
    });

    // Task
    final MenuItem itemTask = menu.findItem(R.id.action_task);
    View actionViewTask = MenuItemCompat.getActionView(itemTask);
    actionViewTask.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            onOptionsItemSelected(itemTask);
        }
    });

    return true;
}

4. 最后，在onOptionsItemSelected()中完成剩下的工作：

@Override
public boolean onOptionsItemSelected(MenuItem item) {

    switch (item.getItemId()) {
        case R.id.action_notification: {
            // Do something
            Toast toast = Toast.makeText(this, "Notification clicked", Toast.LENGTH_SHORT);
            toast.setGravity(Gravity.CENTER, 0, 0);
            toast.show();
            return true;
        }
        case R.id.action_task: {
            // Do something
            Toast toast = Toast.makeText(this, "Task clicked", Toast.LENGTH_SHORT);
            toast.setGravity(Gravity.CENTER, 0, 0);
            toast.show();
            return true;
        }
    }
    return super.onOptionsItemSelected(item);
}

仅供参考，我已通过显示Notification消息检查了Task和click菜单项Toast事件。

<强>输出：

enter image description here

<强>更新

在您更新的代码中使用： 

MenuItemCompat.setActionView(itemNotification, R.layout.custom_action_notification_layout);
View actionViewNotification = MenuItemCompat.getActionView(itemNotification);

而不是 

View actionViewNotification = MenuItemCompat.getActionView(itemNotification);
MenuItemCompat.setActionView(itemNotification, R.layout.custom_action_notification_layout);

希望这会有所帮助〜
