闹铃设置

1、首先创建一个广播提示时间到了

package com.example.alarm;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.widget.Toast;public class AlarmReceiver extends BroadcastReceiver {@Overridepublic void onReceive(Context context, Intent arg1) {// TODO Auto-generated method stubToast.makeText(context, "你设置的闹钟时间到了", Toast.LENGTH_LONG).show();}}

2、注册广播

<receiver android:name=".AlarmReceiver" android:process=":remote" />

3、写布局文件

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:paddingBottom="@dimen/activity_vertical_margin"    android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    android:orientation="vertical"    tools:context=".MainActivity" >    <TextView        android:id="@+id/text"        android:layout_width="wrap_content"        android:layout_height="wrap_content"/>    <Button        android:id="@+id/button1"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:text="设置闹铃"/>        <Button         android:id="@+id/button2"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:text="取消闹铃"/></LinearLayout>

4、写主代码

package com.example.alarm;import java.util.Calendar;import android.os.Bundle;import android.os.Vibrator;import android.app.Activity;import android.app.AlarmManager;import android.app.PendingIntent;import android.app.Service;import android.app.TimePickerDialog;import android.content.Intent;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.TextView;import android.widget.TimePicker;public class MainActivity extends Activity {private Button determine;private Button cancel;private TextView text;Calendar calendar;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);initUI();}//初始化uiprivate void initUI() {// TODO Auto-generated method stub calendar = Calendar.getInstance(); text = (TextView)findViewById(R.id.text); determine = (Button)findViewById(R.id.button1); determine.setOnClickListener(new determineListener()); cancel = (Button)findViewById(R.id.button2); cancel.setOnClickListener(new cancelListener()); }//设置闹铃public class determineListener implements OnClickListener{@Overridepublic void onClick(View arg0) {// TODO Auto-generated method stubcalendar.setTimeInMillis(System.currentTimeMillis());int hour = calendar.get(Calendar.HOUR_OF_DAY);int minute = calendar.get(Calendar.MINUTE);new TimePickerDialog(MainActivity.this,new TimePickerDialog.OnTimeSetListener() {@Overridepublic void onTimeSet(TimePicker view, int hourofDay, int minute) {// TODO Auto-generated method stub//设置日历的时间和当前时间同步calendar.setTimeInMillis(System.currentTimeMillis());//设置小时和分钟 calendar.set(Calendar.HOUR_OF_DAY, hourofDay);                      calendar.set(Calendar.MINUTE, minute);                      //将秒合毫秒设置为0                     calendar.set(Calendar.SECOND, 0);                      calendar.set(Calendar.MILLISECOND, 0);                      //建立Intent和PendingIntent来调用闹钟管理器                     Intent intent = new Intent(MainActivity.this, AlarmReceiver.class);                      PendingIntent pendingIntent = PendingIntent.getBroadcast(MainActivity.this, 0, intent, 0);                      //获取闹钟管理器                     AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);                      //设置闹钟                     alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);                      alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + (10 * 1000),                               (24 * 60 * 60 * 1000), pendingIntent);                      String tmps = "设置闹钟时间为" + format(hourofDay) + ":" +format(minute);                      text.setText(tmps);                    }}, hour, minute, true).show();}}/** *  * @param time * @return */ private String format(int time){         String str = "" + time;         if(str.length() == 1){             str = "0" + str;         }         return str;     } //取消闹铃public class cancelListener implements OnClickListener{@Overridepublic void onClick(View arg0) {// TODO Auto-generated method stub//建立Intent和PendingIntent来调用闹钟管理器Intent intent = new Intent(MainActivity.this, AlarmReceiver.class);             PendingIntent pendingIntent = PendingIntent.getBroadcast(MainActivity.this, 0, intent, 0);             //获取闹钟管理器            AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);             //取消闹钟设置            alarmManager.cancel(pendingIntent);             text.setText("闹铃已取消！"); }}}
