android值制作简易的闹钟和通知栏信息

来源：互联网发布：阜阳市工商局网络监管编辑：程序博客网时间：2024/05/18 18:43

1.制作一次性闹钟

2.制作周期闹钟

3.制作通知信息的弹出框

首先来一个闹钟思维导图吧

简单的思路：

设置（MainActivity）----------->广播接受者（RingReceiver）------------>响铃(RingActivity)---------->设置（MainAcitvity）

再来一个通知的思维导图

代码如下，里面有详解

[html] view plain copy
package com.example.cookie.android0723alarmone;  
  
import android.app.AlarmManager;  
import android.app.Notification;  
import android.app.NotificationManager;  
import android.app.PendingIntent;  
import android.app.TimePickerDialog;

import android.content.Intent;  
import android.support.v7.app.AppCompatActivity;  
import android.os.Bundle;  
import android.support.v7.app.NotificationCompat;  
import android.view.View;  
import android.widget.TimePicker;  
  
import java.util.Calendar;  
  
public class MainActivity extends AppCompatActivity {  
  
    private AlarmManager am;  
    private PendingIntent pendingIntent;  
    private NotificationManager notificationManager;  
  
    @Override  
    protected void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
        setContentView(R.layout.activity_main);  
        //获取闹钟管理器  
        am = (AlarmManager) getSystemService(Context.ALARM_SERVICE);  
        //获取通知管理器  
        notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);  
  
    }  
  
    public void setAlarm(View view){  
        Calendar calendar=Calendar.getInstance();  
        int hour=calendar.get(Calendar.HOUR_OF_DAY);  
        int minute=calendar.get(Calendar.MINUTE);  
        //1.弹出提示框  
        TimePickerDialog timePickerDialog=new TimePickerDialog(this, new TimePickerDialog.OnTimeSetListener() {  
            @Override  
            public void onTimeSet(TimePicker view, int hourOfDay, int minute) {  
                //2.获取闹钟时间  
                Calendar c=Calendar.getInstance();  
                c.set(Calendar.HOUR_OF_DAY,hourOfDay);  
                c.set(Calendar.MINUTE,minute);  
                //3.设置闹钟  
                PendingIntent pendingIntent=PendingIntent.getBroadcast(MainActivity.this,0x101,new Intent("com.example.cookie.android0723alarmone.RING"),0);  
                am.set(AlarmManager.RTC_WAKEUP,c.getTimeInMillis(),pendingIntent);  
            }  
        },hour,minute,true);  
  
timePickerDialog.show();  
    }  
  
    public void setAlarmRepeat(View view){  
        Calendar calendar=Calendar.getInstance();  
        int hour=calendar.get(Calendar.HOUR_OF_DAY);  
        int minute=calendar.get(Calendar.MINUTE);  
        //1.弹出对话框  
        TimePickerDialog timePickerDialog=new TimePickerDialog(this, new TimePickerDialog.OnTimeSetListener() {  
  
  
  
            @Override  
            public void onTimeSet(TimePicker view, int hourOfDay, int minute) {  
                //2.获取闹钟时间  
                Calendar c=Calendar.getInstance();  
                c.set(Calendar.HOUR_OF_DAY,hourOfDay);  
                c.set(Calendar.MINUTE,minute);  
                //3.设置闹钟  
                pendingIntent = PendingIntent.getBroadcast(MainActivity.this,0x101,new Intent("com.example.cookie.android0723alarmone.RING"),0);  
                am.setRepeating(AlarmManager.RTC_WAKEUP,c.getTimeInMillis(),5000, pendingIntent);  
  
            }  
        },hour,minute,true);  
  
        timePickerDialog.show();  
  
    }  
  
    public void stopRepeat(View view){  
        am.cancel(pendingIntent);  
    }  
  
    public void send(View view){  
        //实例化通知  
        NotificationCompat.Builder builder=new NotificationCompat.Builder(this);  
        builder.setContentTitle("提示");  
        builder.setContentText("恭喜您，中奖了，请先汇款给某某激活您的账号");  
        //设置图标  
        builder.setSmallIcon(android.R.drawable.star_on);  
        //使用默认的闪光灯，铃声  
        builder.setDefaults(NotificationCompat.DEFAULT_ALL);  
        Notification notification=builder.build();  
        //发送通知  
        notificationManager.notify(0x101,notification);  
    }  
  
}  

RingReceiver广播接收者

[html] view plain copy
package com.example.cookie.android0723alarmone;  
  
import android.content.BroadcastReceiver;  
import android.content.Context;  
import android.content.Intent;  
import android.util.Log;  
  
/**  
 * Created by Administrator on 2017/7/23 0023.  
 */  
  
public class RingReceiver extends BroadcastReceiver {  
  
    @Override  
    public void onReceive(Context context, Intent intent) {  
        if ("com.example.cookie.android0723alarmone.RING".equals(intent.getAction())){  
            Log.i("test","响铃了！！！");  
            //跳转到activity中  
            Intent intent2=new Intent(context,RingActivity.class);  
            intent2.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);  
            context.startActivity(intent2);  
        }  
    }  
}  

RingActivity闹钟播放

[html] view plain copy
package com.example.cookie.android0723alarmone;  
  
import android.content.BroadcastReceiver;  
import android.content.Context;  
import android.content.Intent;  
import android.util.Log;  
  
/**  
 * Created by Administrator on 2017/7/23 0023.  
 */  
  
public class RingReceiver extends BroadcastReceiver {  
  
    @Override  
    public void onReceive(Context context, Intent intent) {  
        if ("com.example.cookie.android0723alarmone.RING".equals(intent.getAction())){  
            Log.i("test","响铃了！！！");  
            //跳转到activity中  
            Intent intent2=new Intent(context,RingActivity.class);  
            intent2.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);  
            context.startActivity(intent2);  
        }  
    }  
}
