Question

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）：

<ScrollView

Answer 1

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());
 } 
});

ScrollView中带有EditText的Android TextInputLayout隐藏了焦点上的提示
