How to use ShareActionProvider in Action Bar

In this blog,
I will show you how to create a share button in the Action Bar of the MainActivity.

For implementing this we will use ShareActionProvider available in Android.

How to implement

For creating share action, we have to do two things.

First, we have to need a menu item with property actionProviderClass having the value android.widget.ShareActionProvider.

Second thing is to set a share intent for this menu . This can be done in the callback function onCreateOptions.

Step 1:

Define the android:actionProviderClass attribute for the corresponding <item>

share_menu.xml

<item

android:id="@+id/menu_item_share"

android:showAsAction="ifRoom"

android:title="Share"

android:actionProviderClass=

"android.widget.ShareActionProvider" />

...

</menu>

Step 2: Set the Share Intent

private ShareActionProvider mShareActionProvider;

...

@Override

public boolean onCreateOptionsMenu(Menu menu) {

// Inflate menu resource file.

getMenuInflater().inflate(R.menu.share_menu, menu);

// Locate MenuItem with ShareActionProvider

MenuItem item = menu.findItem(R.id.menu_item_share);

// Fetch and store ShareActionProvider

mShareActionProvider = (ShareActionProvider) item.getActionProvider();

// Return true to display menu

return true;

}

// Call to update the share intent

private void setShareIntent(Intent shareIntent) {

if (mShareActionProvider != null) {

mShareActionProvider.setShareIntent(shareIntent);

}

You may only need to set the share intent once during the creation of your menus, or you may want to set it and then update it as the UI changes.
