如何在通知点击时调用非活动方法 [英] How to call a non-activity method on Notification Click

问题描述

我有一个Java类MyClass，其中包含一个名为callMethod的方法.当用户点击通知时，我想调用此方法

I have a java class MyClass which contains a method called callMethod. I want to call this method when user clicks on the notification

下面是我用于生成通知的代码

Below is the code i used to generate the notification

public class MainActivity extends AppCompatActivity {

    Button button;
    NotificationManager mNotifyMgr;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        button = (Button) findViewById(R.id.button);
        mNotifyMgr = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                PendingIntent pendingIntent = PendingIntent.getActivity(MainActivity.this, 0, new Intent(MainActivity.this, MyClass.class), PendingIntent.FLAG_UPDATE_CURRENT);
                Notification notification =
                    new NotificationCompat.Builder(MainActivity.this)
                            .setContentTitle("Notification")
                            .setSmallIcon(R.drawable.ic_launcher)
                            .setContentText("Downloaded")
                            .setContentIntent(pendingIntent)
                            .build();

                mNotifyMgr.notify(1,notification);
            }
        });
    }
}

下面是MyClass

public class MyClass {
    public void callMethod(){
        System.out.println("Notification clicked");
    }
}

请帮助，我已经坚持了一段时间

Please help, I am stuck into this for a while now

推荐答案

您可以执行以下操作:

在创建要放入Notification的PendingIntent时:

Intent notificationIntent = new Intent(MainActivity.this, MyClass.class);
notificationIntent.putExtra("fromNotification", true);
PendingIntent pendingIntent = PendingIntent.getActivity(MainActivity.this, 0, notificationIntent,
         PendingIntent.FLAG_UPDATE_CURRENT);

现在，在MyClass.onCreate()中:

if (getIntent().hasExtra("fromNotification")) {
    callMethod();
}
