NotificationListenerService实施

问题描述

我想实现其在安卓4.3添加NotificationListnerService但我不能够得到通知的详细信息。

I am trying to implement NotificationListnerService which is added in android 4.3 but I am not able to get the notification details.

我的code是如下

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this);
        mBuilder.setSmallIcon(R.drawable.ic_launcher);
        mBuilder.setContentTitle("notification test");
        mBuilder.setContentText("Notification text");
        mBuilder.setAutoCancel(true);
        Intent resultIntent = new Intent(this, ResultActivity.class);
        TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
        // Adds the back stack for the Intent (but not the Intent itself)
        stackBuilder.addParentStack(ResultActivity.class);
        // Adds the Intent that starts the Activity to the top of the stack
        stackBuilder.addNextIntent(resultIntent);
        PendingIntent resultPendingIntent =
                stackBuilder.getPendingIntent(
                    0,
                    PendingIntent.FLAG_UPDATE_CURRENT
                );
        mBuilder.setContentIntent(resultPendingIntent);
        NotificationManager manager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
        manager.notify(1, mBuilder.build());
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

}

public class NotificationListenerTesting extends NotificationListenerService{

    public static String TAG = "NotificationListenerTesting";
    //private StatusBarNotification[] mStatusBarNotification;

    @Override
    public void onCreate(){
        super.onCreate();
        Log.d(TAG, "Inside on create");
    }
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }
    @Override
    public void onNotificationPosted(StatusBarNotification sbn) {
        TAG = "onNotificationPosted";
        Log.d(TAG, "id = " + sbn.getId() + "Package Name" + sbn.getPackageName() +
                "Post time = " + sbn.getPostTime() + "Tag = " + sbn.getTag());
    }
    @Override
    public void onNotificationRemoved(StatusBarNotification sbn) {
        TAG = "onNotificationRemoved";
        Log.d(TAG, "id = " + sbn.getId() + "Package Name" + sbn.getPackageName() +
                "Post time = " + sbn.getPostTime() + "Tag = " + sbn.getTag());

    }

}

Android清单文件

Android manifest file is

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.notificationtest"
    android:versionCode="1"
    android:versionName="1.0" >
    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="18" />
    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.example.notificationtest.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name="com.example.notificationtest.ResultActivity"></activity>
        <service android:name="com.example.notificationtest.NotificationListenerTesting"
            android:label="notification"
            android:permission="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE">
            <intent-filter>
                <action android:name="android.service.notification.NotificationListenerService"/>
            </intent-filter>
        </service>
    </application>
</manifest>

但通知点击或通知后NotificationListenerService是没有得到调用之后，请告诉我错在这还是我错过财产以后？如何实现它？

but after notification click or on notification post NotificationListenerService is not getting called , Whats wrong in this or did I miss somthing ? How to implement it ?

推荐答案

在里面你需要一个弯与GUI线程进行通信，因此您可以创建一个广播来处理GUI交互的NotificationListenerService。

Inside the NotificationListenerService you need a looper to communicate with GUI thread so you can create a broadcast to handle the GUI interaction.

希望这个的例子会帮助你。
