Implement ShareActionProvider for Android 4

In Android 4.0 (API Level 14), android.widget.ShareActionProvider is provided for share action. It is responsible for creating views that enable data sharing and also to show a sub menu with sharing activities if the hosting item is placed on the overflow menu.

It's a example to share plain text using ShareActionProvider.



With share history:



Create /menu/menu.xml to define our ActionBar, with Share action only.

<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@+id/menu_item_share"
        android:showAsAction="ifRoom"
        android:title="Share"
        android:actionProviderClass="android.widget.ShareActionProvider" />
</menu>

Main Java code:

package com.exercise.AndroidShareActionProvider;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.ShareActionProvider;

public class AndroidShareActionProviderActivity extends Activity {
 
 private ShareActionProvider myShareActionProvider;
 
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }

 @Override
 public boolean onCreateOptionsMenu(Menu menu) {
  getMenuInflater().inflate(R.menu.menu, menu);
     MenuItem item = menu.findItem(R.id.menu_item_share);
     myShareActionProvider = (ShareActionProvider)item.getActionProvider();
     myShareActionProvider.setShareHistoryFileName(
       ShareActionProvider.DEFAULT_SHARE_HISTORY_FILE_NAME);
     myShareActionProvider.setShareIntent(createShareIntent());
     return true;
 }
 
 private Intent createShareIntent() {
  Intent shareIntent = new Intent(Intent.ACTION_SEND);
        shareIntent.setType("text/plain");
        shareIntent.putExtra(Intent.EXTRA_TEXT, 
          "http://android-er.blogspot.com/");
        return shareIntent;
    }
 
}
