今天研究了下安卓闹钟，效果分别是响一次和一直不停的响的闹钟

接下来就直接给大家代码，而两种代码都是写在一个项目里面的，所以呢直接就上代码给大家看了

这是main.xml里面的代码

<?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools" android:id="@+id/activity_main"
        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="com.liuqian.android_27alarm.MainActivity">
    
        <Button
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:onClick="setAlarm"
            android:text="设置闹钟一次"
            />
        <Button
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:onClick="setAlarmCycle"
            android:text="设置闹钟周期"
            />
        <Button
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:onClick="cancelCycle"
            android:text="取消周期"
            />
        <Button
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:onClick="sendNotification"
            android:text="发送通知"
            />
      <Button
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:onClick="senddefinitionNotification"
            android:text="发送自定义通知"
            />
    
    </LinearLayout>

接下来的是MainActivity中的的代码

package com.liuqian.android_27alarm;
    
    import android.app.AlarmManager;
    import android.app.Notification;
    import android.app.NotificationManager;
    import android.app.PendingIntent;

    import java.util.Calendar;
    
    public class MainActivity extends AppCompatActivity {
    
        private AlarmManager alarmManager;
        private PendingIntent pendingIntent;
        private NotificationManager notificationManager;
    
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            //获取闹钟管理者
            alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
        }
    
        //设置闹钟一次
        public void setAlarm(View view){
            //获取系统当前时间
            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 builder=new TimePickerDialog(this, new TimePickerDialog.OnTimeSetListener() {
                @Override
                public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
                    //时间到 跳转至activity  在activity中播放音乐
                    Calendar calendar1=Calendar.getInstance();
                    calendar1.set(Calendar.HOUR_OF_DAY,hourOfDay);
                    calendar1.set(Calendar.MINUTE,minute);
                    //跳转
                    Intent intent=new Intent();
                    intent.setAction("com.liuqian.android_27alarm.RING");
                    //PendingIntent
                    PendingIntent pendingIntent=PendingIntent.getBroadcast(MainActivity.this,0x1010,intent,0);
                    //闹钟管理者 参数： 唤醒屏幕，
                    alarmManager.set(AlarmManager.RTC_WAKEUP,calendar1.getTimeInMillis(),pendingIntent);
    
                }
            },hour,minute,true);
            builder.show();
        }
    
        //设置闹钟  周期
         public void setAlarmCycle(View view){
             //获取系统当前时间
             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 builder=new TimePickerDialog(this, new TimePickerDialog.OnTimeSetListener() {
                 @Override
                 public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
                     //时间到 跳转至activity  在activity中播放音乐
                     Calendar calendar1=Calendar.getInstance();
                     calendar1.set(Calendar.HOUR_OF_DAY,hourOfDay);
                     calendar1.set(Calendar.MINUTE,minute);
                     //跳转
                     Intent intent=new Intent();
                     intent.setAction("com.liuqian.android_27alarm.RING");
                     //PendingIntent
                     pendingIntent = PendingIntent.getBroadcast(MainActivity.this,0x1010,intent,0);
                     //闹钟管理者 参数： 唤醒屏幕，
                     //设置周期闹钟
                      alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,calendar1.getTimeInMillis(),5000, pendingIntent);
                 }
             },hour,minute,true);
             builder.show();
        }
    
        //取消周期
         public void cancelCycle(View view){
             alarmManager.cancel(pendingIntent);
        }
    
        //发送通知
         public void sendNotification(View view){
             //实例化通知管理器
             NotificationManager notificationManager=  (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
             //实例化通知
             NotificationCompat.Builder builder=new NotificationCompat.Builder(this);
             //设置值
             builder.setContentTitle("Happy every day");
             builder.setContentText("今天又是美好的一天");
             builder.setDefaults(NotificationCompat.DEFAULT_ALL);
             builder.setAutoCancel(true);
             builder.setSmallIcon(android.R.drawable.ic_media_rew);
             builder.setContentIntent(PendingIntent.getActivity(this,0x102,new Intent(this,RingActivity.class),0));
             //发送通知
             Notification notification=builder.build();
             notificationManager.notify(0x101,notification);
        }
        //发送通知
         public void senddefinitionNotification(View view){
             //实例化通知管理器
             NotificationManager notificationManager=  (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
             //实例化通知
             NotificationCompat.Builder builder=new NotificationCompat.Builder(this);
             //设置值
             builder.setContentTitle("Happy every day");
             builder.setContentText("今天又是美好的一天");
             builder.setDefaults(NotificationCompat.DEFAULT_ALL);
             builder.setAutoCancel(true);
             builder.setSmallIcon(android.R.drawable.ic_media_rew);
             builder.setContentIntent(PendingIntent.getActivity(this,0x102,new Intent(this,RingActivity.class),0));
    
             RemoteViews remoteViews=new RemoteViews(this.getPackageName(),R.layout.activity_ring);
             //发送通知
             Notification notification=builder.build();
             notification.contentView=remoteViews;
             notification.bigContentView=remoteViews;
             notificationManager.notify(0x101,notification);
        }
    
    }

中有几个方法，与xml相对应

接下来是main_ring.xml

<?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:id="@+id/activity_ring"
        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="com.liuqian.android_27alarm.RingActivity">
    
        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="哦多可，你再不起床你就要丢掉这一天最美好的早晨了哦"
            android:textColor="#aabbcc"
            />
    
        <Button
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:onClick="stop"
            android:text="停止"/>
    
    </LinearLayout>
     <?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:id="@+id/activity_ring"
        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="com.liuqian.android_27alarm.RingActivity">
    
        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="哦多可，你再不起床你就要丢掉这一天最美好的早晨了哦"
            android:textColor="#aabbcc"
            />
    
        <Button
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:onClick="stop"
            android:text="停止"/>
    
    </LinearLayout>

接下来是RingActivity的代码

package com.liuqian.android_27alarm;
    
    import android.media.MediaPlayer;
    import android.support.v7.app.AppCompatActivity;
    import android.os.Bundle;
    import android.view.View;
    
    public class RingActivity extends AppCompatActivity {
    
        private MediaPlayer mediaPlayer;
    
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_ring);
            mediaPlayer = MediaPlayer.create(this, R.raw.love);
            mediaPlayer.start();
        }
    
        //停止点击事件
        public void stop(View view){
            mediaPlayer.stop();
            finish();
        }
    
    }

而最后也是最需要注意到就是接收广播

package com.liuqian.android_27alarm;
    
    import android.content.BroadcastReceiver;
    import android.content.Context;
    import android.content.Intent;
    
    /**
     * Created by Administrator on 2017/02/14.
     */
    
    public class RingRecevied extends BroadcastReceiver{
        @Override
        public void onReceive(Context context, Intent intent) {
            if("com.liuqian.android_27alarm.RING".equals(intent.getAction())){
                //跳转到activity  播放闹钟
                Intent intent1=new Intent(context,RingActivity.class);
                //给INtentm设置一个标志位
                intent1.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                context.startActivity(intent1);
            }
        }
    }

也就是跳转页面到RingActivty，然后在manifest文件里面配置就可以了

直接运行代码就可以了。

今天的分享也就到此结束了，希望可以给大家带来一些帮助，如有错误，请指正，本人虚心接受，谢谢！！
