在路径上找不到类“android.view.menu”

Question

在我的 android 应用程序中，我创建了一个菜单，其中包含两个操作保存和刷新，并在另一个活动中调用。

但是它给出了这个异常，如何解决这个问题。 在路径上找不到类“android.view.menu”

这是我的代码，

这是我在main里面的main.xml，

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

    <item
        android:id="@+id/menu_refresh"
        android:orderInCategory="100"
        android:showAsAction="always|withText"
        android:title="@string/menu_refresh"/>
    <item
        android:id="@+id/menu_save"
        android:icon="@android:drawable/ic_menu_save"
        android:orderInCategory="10"
        android:showAsAction="always"
        android:title="@string/menu_save"/>

</menu>

这就是在我的活动中调用的方式，

 @Override
     public boolean onCreateOptionsMenu(Menu menu) 
     {
         MenuInflater inflater = getMenuInflater();
            inflater.inflate(R.menu.main, menu);
            return true;
     }
        @Override
        public boolean onMenuItemSelected(int featureId, MenuItem item) {
            switch (item.getItemId()) {
            case R.id.menu_refresh:

                return true;
            case R.id.menu_save:
                return true;
            }
            return false;
        }

这是我的日志

Answer 1

你把menu.xml文件放在/res/menu/menu.xml里了吗

当 menu.xml 位于 /layout/ 内时，您可能会收到此错误
