Question

我有这个应用程序，您可以按下按钮触发通知。问题是，如果你多按一次，通知会在你点击按钮后频繁出现。是否有任何简单的代码行来避免这种情况？是什么东西可以自动取消旧通知，所以始终只有一个通知？

预先感谢！

public class MainActivity extends ActionBarActivity {

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


@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.main, menu);
    return true;

}


public void sendNotification(View view) {

    switch(view.getId()){

        case R.id.buttom1:
            Notification1();
            break;

        case R.id.buttom2:
            Notification2();
            break;


        }
     }



 private void Notification1() {

   NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
   builder.setAutoCancel(true);
   builder.setContentTitle("BasicNotification");
   builder.setContentText("Test");
   builder.setSmallIcon(R.drawable.icon1);

   Notification notification = builder.build();
   NotificationManager manager = (NotificationManager) this.getSystemService(NOTIFICATION_SERVICE);
   manager.notify((int) System.currentTimeMillis(), notification);

}



private void Notification2() {

   NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
   builder.setAutoCancel(true);
   builder.setContentTitle("BasicNotification");
   builder.setContentText("Test");
   builder.setSmallIcon(R.drawable.icon2);

   Notification notification = builder.build();
   NotificationManager manager = (NotificationManager) this.getSystemService(NOTIFICATION_SERVICE);
   manager.notify((int) System.currentTimeMillis(), notification);

}

}

Answer 1

你试过这个吗？

Button btn = (Button) findViewById(R.id.button1);
btn.setEnabled(false);

更新

声明一个全局变量：

int clickcount=0;

将此信息放入执行Action onClick的方法：

 if(clickcount==2)
            {
buttom1.setEnabled(false);

                               }

Answer 2

为每种通知类型定义一个全局变量：

int notofication1Id = 0;

当您在整数变量

中推送新通知存储ID时

manager.Cancel(notification1Id);
int id = (int) System.currentTimeMillis();
manager.notify(id, notification);
notification1Id = id;

自动在按两次按钮时取消通知？
