//开发手机闹钟主要用到了AlarmManager类，提供了访问系统定时服务的途径，当AlarmManager定时时间到了之后，Intent对象将会被系统广播，进而启动目标程序，进入通知类调用通知package com.example.android28_inform;import android.app.AlarmManager;import android.app.PendingIntent;import android.app.TimePickerDialog;import android.content.Context;import android.content.Intent;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.view.View;import android.widget.TimePicker;import java.util.Calendar;/** * 闹钟 */public class MainActivity extends AppCompatActivity { PRivate AlarmManager alarmManager; private PendingIntent pendingIntent; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); //实例化闹钟管理 alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE); } //设置闹钟 public void one(View view){ //获取当前系统的时间 Calendar calendar= Calendar.getInstance(); int hour=calendar.get(Calendar.HOUR_OF_DAY); int minute=calendar.get(Calendar.MINUTE); //弹出时间对话框 TimePickerDialog timePickerDialog=new TimePickerDialog(this, new TimePickerDialog.OnTimeSetListener() { @Override public void onTimeSet(TimePicker timePicker, int i, int i1) { //确定选择好的时间 Calendar c=Calendar.getInstance(); c.set(Calendar.HOUR_OF_DAY,i); c.set(Calendar.MINUTE,i1); //时间一到，执行相对应的操作 Intent intent=new Intent(); intent.setAction("com.example.android28_inform.dd"); PendingIntent pendingIntent=PendingIntent.getBroadcast(MainActivity.this,0x101,intent,0); //设置闹钟 alarmManager.set(AlarmManager.RTC_WAKEUP,c.getTimeInMillis(),pendingIntent); } },hour,minute,true); timePickerDialog.show(); } //设置周期闹钟 public void week(View view){ //获取当前系统的时间 Calendar calendar=Calendar.getInstance();
