Question

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    button = (Button) findViewById(R.id.button);
    final Intent intent = new Intent(MainActivity.this, AlertActivity.class);
    final PendingIntent pendingIntent = PendingIntent.getActivity(MainActivity.this, 0, intent, 0);
    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            NotificationCompat.Builder builder = new NotificationCompat.Builder(MainActivity.this);
            builder.setContentText("Click here");
            builder.setSmallIcon(R.mipmap.ic_launcher);
            builder.setContentTitle(getString(R.string.app_name));
            builder.addAction(R.mipmap.ic_launcher, "Test", pendingIntent);
            builder.setAutoCancel(true);
            NotificationManagerCompat.from(MainActivity.this).notify(0, builder.build());
        }
    });
}

我还通过删除builder.addAction（）进行了实验，但是当我点击通知时无效。如果在不添加操作的情况下单击通知，我们如何引导用户访问特定活动？另外，在任何一种情况下;除非我手动滑动删除通知，否则我无法解除通知。

Answer 1

autoCancel仅在调用默认通知单击时才会起作用，如果您使用的按钮必须清除自己的通知

在您的NotificationManager实例上调用clear（int id），您的案例id为0

Answer 2

使用setContentIntent可以解决您的问题：

.setContentIntent(PendingIntent.getActivity(this, 0, new Intent(), 0));

完整代码：

button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            NotificationCompat.Builder builder = new NotificationCompat.Builder(MainActivity.this);
            builder.setContentText("Click here");
            builder.setSmallIcon(R.mipmap.ic_launcher);
            builder.setContentTitle(getString(R.string.app_name));
            builder.setAutoCancel(true)
            builder.addAction(R.mipmap.ic_launcher, "Test", pendingIntent);
            builder.setContentIntent(PendingIntent.getActivity(this, 0, new Intent(), 0));
NotificationManager notificationManager= (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, builder.build());
        }
    });

更新：

builder.getNotification().flags |= Notification.FLAG_AUTO_CANCEL;

builder.setAutoCancel（true）无法正常工作
