ShareActionProvider with a split ActionBar

问题

I'm using a ShareActionProvider and would like to take advantage of the split ActionBar when there isn't enough room for it at the top - android:uiOptions="splitActionBarWhenNarrow".

The action works fine when the ActionBar does not need to split:

However when the ActionBar does need to split, the ActionProvider seems to break the lower ActionBar layout completely. It fills the entire viewport below the top ActionBar and the action itself does not appear:

Has anyone been able to use these two features together successfully?

回答1:

This has been fixed in the dev branch of ActionBarSherlock- https://github.com/JakeWharton/ActionBarSherlock/issues/505

You could try that instead.

UPDATE: Now fixed in ActionBarSherlock 4.2.0

Some how creating a share history file fixes this issue

this can be fixed by using a custom share history file on app install.

e.g. call CreateShareHisotryFile() on App Create()

public class YourBrokenAPP extends Application {

  public static SHARE_HISTORY_FILE_NAME = "c_share_hist.xml";

 @Override
 public void onCreate() {
     super.onCreate();  
     CreateShareHisotryFile(); 
 }

 private void CreateShareHisotryFile() {

    String data = "<?xml version='1.0' encoding='UTF-8' standalone='yes' ?> "+
                 "<historical-records>" +
                  "<historical-record activity=\"com.google.android.apps.plus/com.google.android.libraries.social.gateway.GatewayActivity\" time=\"1426500217970\" weight=\"1.0\" />"+
            "</historical-records>";
    try {
        OutputStreamWriter outputStreamWriter = new     OutputStreamWriter(openFileOutput(SHARE_HISTORY_FILE_NAME, Context.MODE_PRIVATE));
         outputStreamWriter.write(data);
        outputStreamWriter.close();
    }
    catch (IOException e) {
        Log.e("Exception", "File write failed: " + e.toString());
    } 
}

then in the fragment's onCreateOptionsMenu use share history file we just created ....

 @Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
     inflater.inflate(R.menu.main, menu);

  // Set up ShareActionProvider's default share intent
    MenuItem shareItem = menu.findItem(R.id.action_share);
    mShareActionProvider = (ShareActionProvider)
           MenuItemCompat.getActionProvider(shareItem);
    mShareActionProvider.setShareHistoryFileName(c_share_hist.xml);
}

Note that historical-records needs @ least one historical-record child element in the xml file

then it's all good ENJOY.......

If does not matter, you can use ActionBarSherlock, this example from demos:
