Question

EditText让我们疯狂！真的！

我们的应用登录界面存在问题。它包含两个EditTexts，但只有第一个（用户名）被聚焦，通过SoftKeyboard只显示触摸/点击用户名EditText。一旦点击用户名EditText，因此SoftKeyboard可见，然后触摸/单击密码EditText它显示焦点（光标在密码EditText中闪烁），但键盘输入将插入用户名EditText。 / p>

现在有趣的部分。我们试图通过屏幕（通过按下电源按钮）将其关闭再打开，然后，出乎意料的是，一切都按预期工作。

我们错过了什么吗？

我们尝试了很多东西：

展平了视图层次结构
仅包含一个包含视图的线性布局的布局
可聚焦，可在触摸模式下专注
从父ScrollView中删除填充视口
将片段转换为活动

我们正在使用Android设计支持库v23.1.1和AppCompat Library v23.1.1
