Setting a custom share icon on Actionbar ShareActionProvider

I'm trying to set the icon ShareActionProvider, need a solid white one instead of the semi transparent white one.

However setting in share_menu.xml and code doesn't work. Just wondering whether anyone has got workaround for this before extending the ShareActionProvider. (I'm using actionbarsherlock)

@Override
public void onCreateOptionsMenu(final Menu menu, final MenuInflater inflater) {
    inflater.inflate(R.menu.share_menu, menu);
    MenuItem actionItem = menu.findItem(R.id.share_action_provider);

    ShareActionProvider actionProvider = (ShareActionProvider) actionItem.getActionProvider();
     actionProvider.setShareIntent(mShareIntent);

    // re-setting the icon as it's not being picked up from the menu xml file
    actionItem.setIcon(R.drawable.ic_action_share);

    super.onCreateOptionsMenu(menu, inflater);

}

share_menu.xml

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

Update: Also tried setting it in the style, but no joy

<style name="Theme.MyApp" parent="Theme.Sherlock.Light">
        <item name="actionModeStyle">@style/ActionModeStyle</item>
        <item name="android:actionModeStyle">@style/ActionModeStyle</item>
</style>

<style name="ActionModeStyle" parent="Widget.Sherlock.ActionMode">
      <item name="actionModeShareDrawable">@drawable/ic_action_share</item>
  </style>

When I am looking to customize the action bar, usually the first place I look is the ActionBarSherlock themes and styles.

I found that the Sherlock theme uses the "actionModeShareDrawable" as found in theme.xml file.

Try changing your theme to include the "actionModeShareDrawable" item directly.

<style name="Theme.MyApp" parent="Theme.Sherlock.Light">
    <item name="actionModeShareDrawable">@drawable/ic_action_share</item>
</style>

For AppCompat the changes to 2 styles are needed:

<style name="MyAppTheme" parent="@style/Theme.AppCompat.Light.DarkActionBar">
    <item name="actionBarWidgetTheme">@style/Theme.AppCompat.CustomShareIcon</item>
    <item name="android:actionBarWidgetTheme">@style/Theme.AppCompat.CustomShareIcon</item>
</style>

In other words, specifiing attr:actionModeShareDrawable in your MyAppTheme is not what you really need, but it should be mentioned in your attr:actionBarWidgetTheme as following:

<style name="Theme.AppCompat.CustomShareIcon" parent="@style/Theme.AppCompat">
    <item name="actionModeShareDrawable">@drawable/abc_ic_menu_share_holo_dark</item> <!-- your icon goes here -->
</style>

UPDATE: Forget about the TRICKY way below, just sub-class ShareActionProvider, return null in onCreateActionView Method, and provide your own icon in menu.xml file, everything will be fine

===========================

I found a very tricky but none-ActionBarSherlock-specific way:

Sub-class ShareActionProvider, with just a little tweak:

@Override
public View onCreateActionView() {
    View target = super.onCreateActionView();
    ViewGroup viewGroup = (ViewGroup) LayoutInflater.from(context).inflate(R.layout.actionbutton_share, null);
    ImageView overlay = (ImageView) viewGroup.findViewById(R.id.overlay);
    ViewGroup container = (ViewGroup) viewGroup.findViewById(R.id.container);
    container.addView(target);
    container.getLayoutParams().width = overlay.getLayoutParams().width;
    container.getLayoutParams().height = overlay.getLayoutParams().height;
    return viewGroup;
}

Create a layout file (R.layout.actionbutton_share), which place the original view at top but transparent to user (Note the "android:alpha=0" part) :

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <FrameLayout
        android:id="@+id/container"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:alpha="0" />

    <ImageView
        android:id="@+id/overlay"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:layout_marginLeft="7dp"
        android:layout_marginRight="7dp"
        android:src="@drawable/yours_whatever_share_icon"
        tools:ignore="ContentDescription" />

</RelativeLayout>

Use the hacked ShareActionProvider in your menu.xml file

vivimice's solution is good, but the icon of last used app for sharing becomes hidden too.

I did custom share icon as a common menu item without any ShareActionProvider, just in onOptionsItemSelected() method used this code:

Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_TEXT, "This is my text to send.");
sendIntent.setType("text/plain");
startActivity(Intent.createChooser(sendIntent, getResources().getText(R.string.send_to)));

It creates not a popup menu, but a chooser dialog.

You can override the non-public attribute like this.

<style name="Theme.MyApp" parent="android:Theme.Holo">
        <item name="*android:actionModeShareDrawalbe">@drawable/icon</item>
</style>

(*) means reference to the non-public resources in Android
