//自已的app接收数据：会自动在分享列表程序中显示自已的app，
public class ReceiverShared extends AppCompatActivity {

}

Intent intent = getIntent();

String action = intent.getAction();

if(Intent.ACTION_SEND.equals(action)){
if("text/plain".equals(type)){
//获取内容：
String info = intent.getStringExtra(Intent.EXTRA_TEXT);

textView.setText(info);
}
}
}

}

清单配置：
//接收数据的activity：
<activity
android:name=".ReceiverShared"
android:label="@string/title_activity_receiver_shared" >

<intent-filter>
<action android:name="android.intent.action.SEND"></action>

<category android:name="android.intent.category.DEFAULT"></category>

<data android:mimeType="text/plain"/>
</intent-filter>

</activity>

在标题栏上显示像qq 一样的分享图标功能：

//菜单项：
<item
android:id="@+id/shares"
android:orderInCategory="200"
android:title="分享"
app:actionProviderClass="android.support.v7.widget.ShareActionProvider"
app:showAsAction="ifRoom"/>

//activity类：
public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

}

@Override
public boolean onCreateOptionsMenu(Menu menu) {

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

MenuItem item = menu.findItem(R.id.shares);
//一定是V7下的包
ShareActionProvider sp = (ShareActionProvider) MenuItemCompat.getActionProvider(item);

Intent intent = new Intent();

intent.setAction(Intent.ACTION_SEND);
intent.setType("text/plain");

//分享的内容
intent.putExtra(Intent.EXTRA_TEXT, "你好啊1");

sp.setShareIntent(intent);

return super.onCreateOptionsMenu(menu);
}
