如何立即更换一个第二电流吐司而不等待当前之一完成？ [英] How to immediately replace the current toast with a second one without waiting for the current one to finish?

问题描述

我有许多按钮。和他们每个人的点击我告诉敬酒。不过，虽然敬酒负载和秀景，另一个按钮被点击并不会显示敬酒，直到正在显示完成的人。

I have many buttons. And on click of each of them I show a Toast. But while a toast loads and show in view, another button is clicked and the toast is not displayed until the one that is being displayed finishes.

所以，我想整理出一个方法来检测是否敬酒在目前的情况下显示。有没有办法知道是否正在显示，这样我可以取消它，并显示一个新的敬酒。

So, I would like to sort out a way to detect if a toast is showing in the current context. Is there a way to know if a toast is being displayed such that I can cancel it and display a new one.

推荐答案

您可以缓存在活动的可变电流吐司，然后只是显示下一个敬酒之前取消它。下面是一个例子：

You can cache current Toast in Activity's variable, and then cancel it just before showing next toast. Here is an example:

Toast m_currentToast;

void showToast(String text)
{
    if(m_currentToast != null)
    {
        m_currentToast.cancel();
    }
    m_currentToast = Toast.makeText(this, text, Toast.LENGTH_LONG);
    m_currentToast.show();

}

另一种方式来即时更新吐司消息：

void showToast(String text)
{
    if(m_currentToast == null)
    {   
        m_currentToast = Toast.makeText(this, text, Toast.LENGTH_LONG);
    }

    m_currentToast.setText(text);
    m_currentToast.setDuration(Toast.LENGTH_LONG);
    m_currentToast.show();
}
