android - ActionBarSherlock ShareActionProvider 问题

Question

ActionBarSherlock (ABS) 是从最新源构建的。使用 ABS ShareActionProvider 时抛出异常。我可以逐步调试 onCreateOptionsMenu() 就好了。如果我取出 @+id/menu_item_share 的 xml，apk 运行正常。

在 Debug模式下，我可以逐步完成的最深入操作是 SherlockFragmentActivity 中的 onCreatePanelMenu()。

主菜单.xml:

 <item android:id="@+id/menu_item_share"
      android:icon="@+id/ic_action_share"
      android:showAsAction="ifRoom"
      android:title="@string/menu_share"
      android:actionProviderClass="com.actionbarsherlock.widget.ShareActionProvider" 
 />

相关代码:

import com.actionbarsherlock.app.SherlockFragmentActivity;
import com.actionbarsherlock.view.Menu;
import com.actionbarsherlock.view.MenuInflater;
import com.actionbarsherlock.view.MenuItem;
import com.actionbarsherlock.widget.ShareActionProvider;

public class MyActivity extends SherlockFragmentActivity {

. . . 

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getSupportMenuInflater();
    inflater.inflate(R.menu.main_menu, menu);

    mShareActionProvider = (ShareActionProvider) menu.findItem(R.id.menu_item_share).getActionProvider();

    if(this.verse.verse != null)
        mShareActionProvider.setShareIntent(getDefaultShareIntent());

    return true;
}

public Intent getDefaultShareIntent(){
    Intent sendIntent = new Intent();
    sendIntent.setAction(Intent.ACTION_SEND);
    sendIntent.putExtra(Intent.EXTRA_TEXT, "text to share");
    sendIntent.setType("text/plain");

    return sendIntent;
}
. . . 

}

异常(exception):

Answer 1

  android:icon="@+id/ic_action_share"

这是错误的。您没有分配可绘制对象，只是将 Id 添加到 R.java 类中。你需要在这里引用一个图标，像这样:

   android:icon="@drawable/ic_action_share"
