如何在Android上启动NotificationListenerService
作者:互联网
我想使用NotificationListenerService在Android手机上访问通知.我检查了很多教程,但找不到他们在哪里调用该服务.
我应该在MainActivity上使用bindService还是startService吗?意图应该如何?有人可以告诉我这个语法吗?
查看我正在研究的服务实现之一:
public class NLService extends NotificationListenerService {
Context context;
@Override
public void onCreate() {
super.onCreate();
context = getApplicationContext();
}
@Override
public void onNotificationPosted(StatusBarNotification sbn) {
String pack = sbn.getPackageName();
String ticker ="";
if(sbn.getNotification().tickerText !=null) {
ticker = sbn.getNotification().tickerText.toString();
}
Bundle extras = sbn.getNotification().extras;
String title = extras.getString("android.title");
String text = extras.getCharSequence("android.text").toString();
int id1 = extras.getInt(Notification.EXTRA_SMALL_ICON);
Bitmap id = sbn.getNotification().largeIcon;
Log.i("Package",pack);
Log.i("Ticker",ticker);
Log.i("Title",title);
Log.i("Text",text);
Intent msgrcv = new Intent("Msg");
msgrcv.putExtra("package", pack);
msgrcv.putExtra("ticker", ticker);
msgrcv.putExtra("title", title);
msgrcv.putExtra("text", text);
if(id != null) {
ByteArrayOutputStream stream = new ByteArrayOutputStream();
//id.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] byteArray = stream.toByteArray();
msgrcv.putExtra("icon",byteArray);
}
LocalBroadcastManager.getInstance(context).sendBroadcast(msgrcv);
}
@Override
public void onNotificationRemoved(StatusBarNotification sbn) {
Log.i("Msg","Notification Removed");
}
}
解决方法:
为了监听传入的通知,他们无需显式启动它.首先使用以下权限在清单中定义您的服务-
android.permission.BIND_NOTIFICATION_LISTENER_SERVICE
<service android:name=".MyNotificationListener"
android:permission="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE">
<intent-filter>
<action android:name="android.service.notification.NotificationListenerService" />
</intent-filter>
</service>
要注意的另一件事是,您必须使用以下意图来授予权限-
Intent intent=new Intent("android.settings.ACTION_NOTIFICATION_LISTENER_SETTINGS");
或通过手动授予通知访问权限.
