简易发送短信app

SmsManager发送短信

1，

//获取SMSManager管理器
        smsmanager=SmsManager.getDefault();

2,

//创建一个PendingIntent对象
PendingIntent pi=PendingIntent.getActivity(MainActivity.this, 0, new Intent(), 0);
//发送短信
smsmanager.sendTextMessage(number.getText().toString(), null, content.getText().toString(), pi, null);

SmsManager.sendTextMessage(String destinationAddress, String scAddress, String text, PendingIntent sentIntent, PendingIntent deliveryIntent)

本程序可以直接填入对方号码，输入内容发送短信，也可以点击通讯录按钮，从通讯录中获取联系人电话
