总结一下，我有一个listview，列表视图中的每个项目都有一个button。按钮可以处于两种状态：突出显示或不突出显示。我在屏幕底部还有一个edittext，其中包含用于显示结果的桩和文本视图。每个button文本都包含一个双精度数;当按钮处于突出显示状态时，桩号乘以按钮上的双倍，结果显示在文本视图中。如果突出显示多个按钮，则结果为所有突出显示的按钮。当用户更改赌注时，结果会动态变化;这是使用下面的代码和onTextChangedListener完成的。当用户首先输入赌注然后进行选择时，一切都很好。但是，我的问题是，当用户FIRST使用edittext为空时进行选择并且AFTER将比特输入到edittext中时没有反应;然后，用户必须重新选择他所有的选择，以使系统正常工作。我正在寻找有关如何更改以下代码以解决此问题的建议，并使应用程序以相同的方式运行，无论是先输入赌注还是首先进行选择。单击列表视图中的任何按钮时，将执行以下方法。我们关注的editText是变量mEdit。其余代码与问题无关，但我将其包含在内以避免混淆。
