Share button on ActionBar appears twice

I created a share button in my action bar, but it seems to appear twice.

enter image description here

The menu XML

is below:

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

    <item
        android:id="@+id/action_share"
        android:title="@string/action_share"
        app:showAsAction="always"
        app:actionProviderClass="android.support.v7.widget.ShareActionProvider"   
    />

</menu>

And it is created in onCreateOptionsMenu

the view.

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

    MenuItem menuItem = menu.findItem(R.id.action_share);

    mShareActionProvider =
            (ShareActionProvider) MenuItemCompat.getActionProvider(menuItem);

    if(mShareActionProvider != null && !mForecastString.isEmpty()){
        mShareActionProvider.setShareIntent(createShareForecastIntent());
    } else{
        Log.d(LOG_TAG, "Share Action provider is null?");
    }

    super.onCreateOptionsMenu(menu,inflater);
}

How can a share button appear twice if defined, inflated, and created only once?

You inflate the menu twice, both in Control and in Fragment.



Removing inflation alone should fix the problem.

Use menu.clear () before setting menu options;



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

    MenuItem menuItem = menu.findItem(R.id.action_share);

    mShareActionProvider =
            (ShareActionProvider) MenuItemCompat.getActionProvider(menuItem);

    if(mShareActionProvider != null && !mForecastString.isEmpty()){
        mShareActionProvider.setShareIntent(createShareForecastIntent());
    } else{
        Log.d(LOG_TAG, "Share Action provider is null?");
    }

    super.onCreateOptionsMenu(menu,inflater);
}

This is due to the repeated inflation of the menu. use menu.clear () before inflation.

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