拨电话

intent.setData(Uri.parse("tel:187********"));

发消息

intent.putExtra("sms_body", "Hello world");

 

 

使拨号和发短信能通过android的允许

在AndroidManifest.xml中添加，是application的节点下面添加。

<uses-permission android:name="android.permission.CALL_PHONE"/>
<uses-permission android:name="android.permission.SEND_SMS"/>
