Android:调用打电话和发短信及intent一些其他用法

1.打电话

可以自己写界面，在button的单击事件中添加如下代码即可：

Intent intent = new Intent();

   intent.setAction("android.intent.action.CALL");

   intent.setData(Uri.parse("tel:"+
mobile));//mobile为你要拨打的电话号码，模拟器中为模拟器编号也可

   startActivity(intent);

需要添加打电话权限：

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

2.发短信

和打电话差不多，在button的单击事件中添加如下代码：

SmsManager
smsManager = SmsManager.getDefault();

    ArrayList<String> texts =
smsManager.divideMessage(content);//拆分短信,短信字数太多了的时候要分几次发

    for(String text : texts){

     smsManager.sendTextMessage(mobile, null, text,
null, null);//发送短信,mobile是对方手机号
    }

对应发短信权限：

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