java - 如何使用 subItem InflateException 修复 OptionsMenu

Question

我有一个带有子项目菜单的选项菜单

当我单击选项菜单时，我的应用程序崩溃，但无法解密日志

我想要一个选项按钮来打开 3 个选项菜单子(monad)项

我检查了一些教程，但我看不出我错在哪里

<?xml version="1.0" encoding="utf-8"?>

<item
    android:id="@+id/search_button_main_activity"
    android:icon="@drawable/search_button"
    android:title="@string/search_button"
    app:showAsAction="ifRoom"/>
<item
    android:id="@+id/notifications_button"
    android:title="@string/notifications_button"
    app:showAsAction="never" />
<item
    android:id="@+id/help_button"
    android:orderInCategory="100"
    android:title="@string/help_button"
    app:showAsAction="never" />
<item
    android:id="@+id/about_button"
    android:orderInCategory="100"
    android:title="@string/about_button"
    app:showAsAction="never" />

 @Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.menu_activity_main, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case R.id.search_button_main_activity:
            this.launchSearchActivity();
            return true;
        case R.id.notifications_button:
            Toast.makeText(this, "This will launch notification feature", Toast.LENGTH_SHORT).show();
            return true;
        case R.id.about_button:
            Toast.makeText(this, "This will launch about feature", Toast.LENGTH_SHORT).show();
            return true;
        case R.id.help_button:
            Toast.makeText(this, "This will launch help feature", Toast.LENGTH_SHORT).show();
            return true;
        default:
            return super.onOptionsItemSelected(item);
    }
}

这是错误消息:

日志无法告诉我崩溃来自何处

Answer 1

您收到的错误不是来自菜单。它很可能来自您在 launchSearchActivity 中调用的布局。

据我了解，您想要的内容如下

您可以使用下面给出的 xml 来创建一个类似的菜单(请根据需要更改可绘制对象、名称和 id)

<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools" tools:context=".MainActivity">
<item
    android:id="@+id/action_rate" android:title="@string/action_rate"
    android:icon="@drawable/ic_favorite_border_black_24dp" app:showAsAction="always|withText"/>
<item
    android:icon="@drawable/ic_more_vert_black_24dp"
    android:title="More"
    app:showAsAction="always">
    <menu>
        <item android:id="@+id/action_contact_us" android:icon="@drawable/ic_email_black_24dp"
            android:title="@string/action_about"
            android:orderInCategory="102" app:showAsAction="never"/>
        <item android:id="@+id/action_moreapps" android:icon="@drawable/ic_shop_black_24dp"
            android:title="@string/action_more_apps"
            android:orderInCategory="103" app:showAsAction="never"/>
        <item android:id="@+id/action_exit" android:icon="@drawable/ic_close_black_24dp"
            android:title="@string/action_exit"
            android:orderInCategory="107" app:showAsAction="never"/>
    </menu>
</item>
