Question

我得到了这个例外：

java.lang.ClassCastException: android.widget.ShareActionProvider cannot be cast to com.actionbarsherlock.view.ActionProvider
        at com.actionbarsherlock.view.MenuInflater$MenuState.readItem(MenuInflater.java:389)

        at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:551)
        at dalvik.system.NativeStart.main(Native Method)

这个方法：

public boolean onCreateOptionsMenu(Menu menu)
{
    MenuInflater inflater = getSupportMenuInflater();
    inflater.inflate(R.menu.main_menu, menu);
    return true;
}

在这一行：

    inflater.inflate(R.menu.main_menu, menu);

这是我的main_menu.xml

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

<item android:id="@+id/menu_item_share"         
android:showAsAction="ifRoom"         
android:title="Share"         
android:actionProviderClass="android.widget.ShareActionProvider" />  

</menu>

我要做的是让ListNavigation和ActionbarShare都显示在导航栏上。有谁知道如何修复此崩溃？

谢谢，亚历

ActionBarSherlock的MenuInflater需要com.actionbarsherlock.view.ActionProvider.

您的actionProviderClass是android.widget.ShareActionProvider，显然不会扩展ActionBarSherlock的ActionProvider。因此ClassCastException。

ActionBarSherlock附带了一些示例，其中一些示例显示了ActionProviders的使用。查看文件夹

ActionBarSherlock\actionbarsherlock-samples\demos\res\menu

获取两个菜单xml文件和

的示例

ActionBarSherlock\actionbarsherlock-samples\demos\src\com\actionbarsherlock\sample\demos 对于相关来源

(ShareActionProviders.java and ActionProviders.java)
