在特定时间段内禁用 Android 应用程序上的按钮

2022-01-19 00:00:00 switch-statement android java

我正在 android studio 中构建一个登录风格的应用程序.作为其中的一部分，我创建了一个规则，如果监视无效登录尝试次数的计数器变为 0.我目前知道当计数器变为 0 时，登录按钮被禁用.我想知道是否有任何方法可以在一段时间内禁用此按钮，而不是无限期?

I'm building a login style application within android studio. As part of this I have created a rule that if the counter which monitors the number of invalid login attempts, gets to 0. I've currently got it that when the counter gets to 0, the login button is disabled. I was wondering if there is any way of disabling this button for a set period of time, rather than for infinity?

switch (counter) {
    case 0:
        b1.setEnabled(false);
    break;

    case 1:
         tx1.setBackgroundColor(Color.RED);
    break;

    case 2:
        tx1.setBackgroundColor(Color.YELLOW);
    break;
}

推荐答案

使用以下代码.当您放入 OnCreate() 方法时，当活动或片段开始时，它将在 5 秒后禁用按钮.

Use following code. it will disabled button after 5 seconds when activity or fragment start when you put in OnCreate() method. 

new Handler().postDelayed(new Runnable() 
    {
        public void run() 
        {
            b1.setEnabled(false);
        }
    }, 5000    //Specific time in milliseconds
);
