Android 開機啓動通知

效果圖：

學習：

1.靜態註冊實現開機啓動

<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.通知的建立

step1：須要一個NotificationManager來對通知進行管理

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

step2:建立一個Notification對象，這個對象用於存儲通知所需的各類信息。

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:調用NotificationManager的notify()讓通知顯示出來。

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

 

源碼：

import android.app.Notification;
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, "闂歸搩鍝嶄簡, 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());
    }
