将我的项目更新为使用appcompat库的21.0.0版本后,我在使用gridview多选模态事件创建的上下文菜单时遇到了问题。相同的代码在appcompat v20中可以正常工作。
这是主活动的相关部分:
public class MainActivity extends android.support.v7.app.ActionBarActivity
implements AbsListView.MultiChoiceModeListener {
...
mGridView.setChoiceMode(AbsListView.CHOICE_MODE_MULTIPLE_MODAL);
mGridView.setMultiChoiceModeListener(this);
@Override
public boolean onCreateActionMode(final ActionMode mode, final Menu menu) {
mode.setTitle("Started");
mode.getMenuInflater().inflate(R.menu.context_menu, menu);
return true;
}
}
这是 context_menu.xml 文件:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="@+id/menu_item_share"
android:title="Share..."
app:showAsAction="ifRoom"
android:icon="@android:drawable/ic_menu_share"
app:actionProviderClass="android.support.v7.widget.ShareActionProvider" />
</menu>
这是我得到的堆栈跟踪:

我很好奇是否有人遇到了同样的问题,是否有解决方法。
