如果我将一个EditText集中在ScrollView中,就会发生这种情况(很好):
然后,我将焦点放在下面的EditText并从第一张图片重新聚焦EditText,然后发生这种情况:
提示未显示或显示不正确(取决于滚动视图)。
部分解决方案: Scrollview看到我想要关注EditText而不是周围的android.support.design.widget.TextInputLayout元素。因此,它不关心是否显示提示。
如何解决? 我的XML(基本上是一个包含一些包含带有EditTexts的android.support.design.widget.TextInputLayout的linearlayouts的scrollview):

使用此代码滚动到edittext视图的正确位置
your_scrollview.post(new Runnable() {
@Override
public void run() {
your_scrollview.smoothScrollTo(0, your_EditBox.getBottom());
}
});
