Android 开机启动通知

效果图：

学习：

1.静态注册实现开机启动

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

        <receiver android:name="com.example.alarmmanagerdemo.AlarmReceiver" >
            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED" />
            </intent-filter>
        </receiver>

2.通知的创建

step1：需要一个NotificationManager来对通知进行管理

 NotificationManager manager = (NotificationManager)context.getSystemService(android.content.Context.NOTIFICATION_SERVICE); 

step2:创建一个Notification对象，这个对象用于存储通知所需的各种信息。

NotificationCompat.Builder builder = new NotificationCompat.Builder(context);
        builder.setContentTitle("Mission Of Everyday").setContentText("Remeber Vocabulary, Exercise, Speaking English").setSmallIcon(R.drawable.sun).setDefaults(Notification.DEFAULT_ALL).setAutoCancel(true).setSubText("                          For Dream!");

step3:调用NotificationManager的notify()让通知显示出来。

manager.notify(1, builder.build());

import android.app.NotificationManager;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.support.v4.app.NotificationCompat;
import android.widget.Toast;


public class AlarmReceiver extends BroadcastReceiver {
    private NotificationManager manager;
    @Override
    public void onReceive(Context context, Intent intent) {
        //Toast.makeText(context, "闂归搩鍝嶄簡, 鍙�互鍋氱偣浜嬫儏浜唦~", Toast.LENGTH_LONG).show();
        Toast.makeText(context, "Boot Complete", Toast.LENGTH_LONG).show();
        manager = (NotificationManager)context.getSystemService(android.content.Context.NOTIFICATION_SERVICE);
        
        NotificationCompat.Builder builder = new NotificationCompat.Builder(context);
        builder.setContentTitle("Mission Of Everyday").setContentText("Remeber Vocabulary, Exercise, Speaking English").setSmallIcon(R.drawable.sun).setDefaults(Notification.DEFAULT_ALL).setAutoCancel(true).setSubText("                          For Dream!");
        manager.notify(1, builder.build());
    }
