我已经阅读了有关此错误及其与我的 java 路径有关的内容。
我尝试了各种解决方案,但仍然出现此错误。
这是我的 java 路径顺序和导出:
我的代码:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:id="@+id/save_wotkout_ab"
android:title="Add Item"
android:icon="@android:drawable/ic_menu_save"
android:showAsAction="ifRoom"/>
<item android:id="@+id/delete_workout_ab"
android:title="Add Item"
android:icon="@android:drawable/ic_delete"
android:showAsAction="ifRoom"/>
<item android:id="@+id/search_ab"
android:title="Add Item"
android:icon="@android:drawable/ic_menu_search"
android:actionViewClass="android.support.v7.widget.SearchView"
android:showAsAction="ifRoom|collapseActionView"/>
<item
android:id="@+id/action_share"
android:actionProviderClass="android.support.v7.widget.ShareActionProvider"
android:showAsAction="ifRoom"
android:title="share"/>
</menu>
例外情况是:
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu items for use in the action bar
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.add_workout_actionbar, menu);
MenuItem shareItem = menu.findItem(R.id.action_share);
mShareActionProvider = (ShareActionProvider)
MenuItemCompat.getActionProvider(shareItem);
mShareActionProvider.setShareIntent(getDefaultIntent());
return super.onCreateOptionsMenu(menu);
}
感谢您的帮助
