Android定时发送短信完整详细示例
MainActivity如下:
package cc.testsms;
import java.util.Calendar;
import java.util.Locale;
import android.app.Activity;
import android.app.AlarmManager;
import android.app.DatePickerDialog;
import android.app.Dialog;
import android.app.PendingIntent;
import android.app.TimePickerDialog;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.text.TextUtils;
import android.view.View;
import android.widget.Button;
import android.widget.DatePicker;
import android.widget.EditText;
import android.widget.TimePicker;
import android.widget.Toast;
/**
* Demo描述:
* 手机定时发送短信的实现

* Thank you very much
*
* 暂存问题:
* 1 设置定时短信后关机重启,定时短信失效
* 可以考虑将定时短信存入数据库或者本地
* 2 连续多次设置定时短信,但只有最后一个会被触发.
* 解决方式可以参见闹钟的源码.
