请帮助我将大写键盘转换为小写键盘。这是一个老问题。只是偶然发现的。以下是我对答案的看法，如果有人感兴趣，我会提供给大家参考。 加： 其中，键盘是使用一个XML充气的键盘实例。例如：
keyboard = new Keyboard(this, R.xml.lowercase);
您应该使用switch case语句，而不是所有if-else语句。这是一个老问题。只是偶然发现的。以下是我对答案的看法，如果有人感兴趣，我会提供给大家参考。 加： 其中，键盘是使用一个XML充气的键盘实例。例如：

您应该使用switch case语句，而不是所有if-else语句。从Android的软键盘示例中获得了解决方案。您可以共享一个小片段或参考代码。。我也在寻找samegot解决方案，例如Android的软键盘。你能分享一个小片段或参考代码吗。。我也在寻找同样的目标
keyboard = new Keyboard(this, R.xml.lowercase);
