Android(安卓)NotificationListenerService监听获取通知栏通知和短信信息

为了实时获取通知栏状态的消息状态和内容进行获取，能够判断当前消息移除或者推送

A service that receives calls from the system when new notifications are
posted or removed, or their ranking changed.
To extend this class, you must declare the service in your manifest file with
the {@link android.Manifest.permission#BIND_NOTIFICATION_LISTENER_SERVICE} permission
and include an intent filter with the {@link #SERVICE_INTERFACE} action. For example:

监听注册通知监听服务

    <service            android:name=".permission.service.GuardNotificationListenerService"            android:label="@string/accessibility_service_label"            android:enabled="true"            android:permission="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE">            <intent-filter>                <action android:name="android.service.notification.NotificationListenerService" />            </intent-filter>        </service>

判断监听权限是否开启

    // 判断是否开启监听通知权限    if (NotificationManagerCompat.getEnabledListenerPackages(this).contains(getPackageName())) {Intent serviceIntent =new Intent(this, GuardNotificationListenerService.class);        startService(serviceIntent);    }else {// 去开启 监听通知权限        startActivity(new Intent("android.settings.ACTION_NOTIFICATION_LISTENER_SETTINGS"));    }}

实现监听服务 NotificationListenerService

import android.app.Notification;import android.nfc.Tag;import android.os.Bundle;import android.service.notification.NotificationListenerService;import android.service.notification.StatusBarNotification;import android.text.SpannableString;import android.text.TextUtils;import com.mo.util.Log;/** * @Description: * @Author: lhw * @CreateDate: 2020/2/22 17:59 */public class GuardNotificationListenerService extends NotificationListenerService {    public final  static String TAG=GuardNotificationListenerService.class.getSimpleName();    @Override    public void onListenerConnected() {        super.onListenerConnected();        Log.d(TAG,"onListenerConnected");    }    @Override    public void onListenerDisconnected() {        super.onListenerDisconnected();        Log.d(TAG,"onListenerDisconnected");    }    @Override    public void onNotificationPosted(StatusBarNotification sbn) {        Log.d(TAG,"onNotificationPosted");        showMsg(sbn);    }    private void showMsg(StatusBarNotification sbn) {        Bundle extras = sbn.getNotification().extras;               String packageName = sbn.getPackageName();        if (extras!=null){        //获取通知消息标题            String title = extras.getString(Notification.EXTRA_TITLE);            // 获取通知消息内容            Object msgText = extras.getCharSequence(Notification.EXTRA_TEXT);//注意：获取的通知信息和短信的传递内容不一样 短信为SpannableString 这里容易造成转换异常            if (msgText instanceof SpannableString){                Log.d(TAG,"is SpannableString ...."+((SpannableString) msgText).subSequence(0,((SpannableString) msgText).length()));            }else{                Log.d(TAG,"showMsg packageName="+packageName+",title="+title+",msgText="+msgText);            }        }else{            Log.d(TAG,"is null ...."+packageName);        }    }    @Override    public void onNotificationRemoved(StatusBarNotification sbn) {        Log.d(TAG,"onNotificationRemoved");        showMsg(sbn);    }}
