NotificationListenerService监听获取手机通知

使用NotificationListenerService来监听手机通知，未接电话、未读消息什么的。广告都能监听到

首先写一个类继承NotificationListenerService

这里需要用户手机开启权限

public class NotificationCollectorService extends NotificationListenerService {
    //来通知时的调用
    @Override
    public void onNotificationPosted(StatusBarNotification sbn) {
        super.onNotificationPosted(sbn);
        Notification notification = sbn.getNotification();
        if (notification == null) {
            return;
        }

        Bundle extras = notification.extras;
        String content = "";
        if (extras != null) {
            // 获取通知标题
            String title = extras.getString(Notification.EXTRA_TITLE, "");
            // 获取通知内容
            content = extras.getString(Notification.EXTRA_TEXT, "");
            Log.i("包名：",sbn.getPackageName()+"标题:"+title+"内容:"+content);
        }
        switch (sbn.getPackageName()){
            case "com.tencent.mm":
                Log.i("微信",content);
                break;
            case "com.android.mms":
                Log.i("短信信",content);
                break;
            case "com.tencent.mqq":
                Log.i("qq",content);
                break;
            case "com.tencent.tim":
                Log.i("tim",content);
                break;
            case "com.android.incallui":
                Log.i("电话",content);
                break;
        }

    }

    //删除通知时的调用
    @Override
    public void onNotificationRemoved(StatusBarNotification sbn) {
        super.onNotificationRemoved(sbn);
        Notification notification = sbn.getNotification();
        if (notification == null) {
            return;
        }
        Bundle extras = notification.extras;
        String content = "";
        if (extras != null) {
            // 获取通知标题
            String title = extras.getString(Notification.EXTRA_TITLE, "");
            // 获取通知内容
            content = extras.getString(Notification.EXTRA_TEXT, "");
            Log.i("删包名：",sbn.getPackageName()+"标题:"+title+"内容:"+content);
        }
        switch (sbn.getPackageName()){
            case "com.tencent.mm":
                Log.i("删微信",content);
                break;
            case "com.android.mms":
                Log.i("删短信",content);
                break;
            case "com.tencent.mqq":
                Log.i("删qq",content);
                break;
            case "com.tencent.tim":
                Log.i("删tim",content);
                break;
            case "com.android.incallui":
                Log.i("删电话",content);
                break;
        }

    }

}

在清单文件中注册*****必须要写的

<service android:name=".NotificationCollectorService"
    android:permission="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE">
<intent-filter>
    <action android:name="android.service.notification.NotificationListenerService" />
</intent-filter>
</service>

在mainActivity中需要加入是否授权的逻辑判断。在这里解决了一个问题，就是在第一次打开应用可以正常监听，但是放用户杀死这个进程之后，就兼听不到了，因为 NotificationListenerService 被杀后再次启动时，并没有去 bindService ，所以导致监听效果无效。。。解决办法可就是把应用的NotificationListenerService实现类disable再enable，即可触发系统rebind操作---详见代码，注释很清晰

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        if (!isNotificationListenerEnabled(this)){
            openNotificationListenSettings();
        }
        toggleNotificationListenerService();

    }
    //检测通知监听服务是否被授权
    public boolean isNotificationListenerEnabled(Context context) {
        Set<String> packageNames = NotificationManagerCompat.getEnabledListenerPackages(this);
        if (packageNames.contains(context.getPackageName())) {
            return true;
        }
        return false;
    }
    //打开通知监听设置页面
    public void openNotificationListenSettings() {
        try {
            Intent intent;
            if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP_MR1) {
                intent = new Intent(Settings.ACTION_NOTIFICATION_LISTENER_SETTINGS);
            } else {
                intent = new Intent("android.settings.ACTION_NOTIFICATION_LISTENER_SETTINGS");
            }
            startActivity(intent);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    //把应用的NotificationListenerService实现类disable再enable，即可触发系统rebind操作
    private void toggleNotificationListenerService() {
        PackageManager pm = getPackageManager();
        pm.setComponentEnabledSetting(
                new ComponentName(this, NotificationCollectorService.class),
                PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);

        pm.setComponentEnabledSetting(
                new ComponentName(this, NotificationCollectorService.class),
                PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP);
    }
}

OK。这样就可以监听到手机的通知栏信息了。效果图我就不贴了。大家可以自己实现来看看
