5分钟创建一个android监听通知服务

5分钟创建一个android监听通知服务

1、打开android studio，新建项目，选择一个基础的Activity

2、设置启动Activity名称

3、新建一个class，基类为android.service.notification.NotificationListenerService，勾选show select overrides dialog

4、选择需要重写的方法

5、在onNotificationPosted中记录通知的消息文字

Log.v("BFW", sbn.getNotification().tickerText.toString());

在AndroidManifest.xml加入

<service android:name="wiki.bfw.readnoticle.NotifyService" android:priority="1000" android:label="通知监控" android:permission="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE">
            <intent-filter>
                <action android:name="android.service.notification.NotificationListenerService">
            </action></intent-filter>
        </service>

6、在启动的activity中启动service

7、加入设置通知权限的方法

8、编译运行后的效果，先点击右下角图标，调到授权页面，授权app使用通知监听

9、模拟器中发布一条短信

10、我们可以看到日志中打印出刚才的短信内容，监听成功了

主要代码如下

NotifyActivity.java

package wiki.bfw.readnoticle;

import android.content.Intent;
import android.os.Bundle;

import com.google.android.material.floatingactionbutton.FloatingActionButton;
import com.google.android.material.snackbar.Snackbar;

import androidx.appcompat.app.AppCompatActivity;
import androidx.appcompat.widget.Toolbar;

import android.provider.Settings;
import android.view.View;

public class NotifyActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_notify);
        Toolbar toolbar = findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        Intent intent = new Intent(NotifyActivity.this, NotifyService.class);//启动服务
        startService(intent);//启动服务
        FloatingActionButton fab = findViewById(R.id.fab);
        fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Intent intent_s = new Intent(Settings.ACTION_NOTIFICATION_LISTENER_SETTINGS);
                startActivity(intent_s);
                Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
                        .setAction("Action", null).show();
            }
        });
    }

}

package wiki.bfw.readnoticle;

import android.content.Intent;
import android.os.IBinder;
import android.service.notification.NotificationListenerService;
import android.service.notification.StatusBarNotification;
import android.util.Log;

public class NotifyService extends NotificationListenerService {
    @Override
    public void onNotificationPosted(StatusBarNotification sbn, RankingMap rankingMap) {
        Log.v("BFW", sbn.getNotification().tickerText.toString());
        super.onNotificationPosted(sbn, rankingMap);
    }

    @Override
    public void onNotificationRemoved(StatusBarNotification sbn) {
        super.onNotificationRemoved(sbn);
    }

    @Override
    public IBinder onBind(Intent intent) {
        return super.onBind(intent);
    }

    @Override
    public boolean onUnbind(Intent intent) {
        return super.onUnbind(intent);
    }

    @Override
    public void onCreate() {
        super.onCreate();
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        return super.onStartCommand(intent, flags, startId);
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
    }
}
