Question

我已经为我的android应用创建了导航视图，但是当活动尝试启动并崩溃时，我收到以下错误消息。

我已经看过其他用户类似的问题，但是我仍然无法查明问题。

任何帮助将不胜感激。

logcat也指向task_list.java的第60行，即：

setContentView(R.layout.navigation_drawer);

这最初是指向基本的xml活动。

Answer 1

问题来自Navigation_menu xml

最初第二个菜单（高级选项）未包含在项目中。

这是正确的布局

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

<group android:checkableBehavior="single">

    <item
        android:title="Complete"
        android:id="@+id/complete">
    </item>
    <item
        android:title="In-Progress"
        android:id="@+id/inProgress">
    </item>
    <item
        android:title="Not Started"
        android:id="@+id/notStarted">
    </item>
</group>

<item android:title="Advanced Options">

    <menu>

        <item
            android:title="Other Items"
            android:id="@+id/other">
        </item>

    </menu>

</item>


 </menu>

Answer 2

删除以下行并运行

" <item name="android:textColor">@color/black</item>"
