当键盘出现时，如何使按钮不与 EditText 重叠？

Question

屏幕底部有一个bottom_sheet_behavior按钮，当键盘出现时，它显示在键盘的顶部。我想保持这种状态。问题是，当我选择要输入的 EditText 时，按钮显示在键盘顶部，它与 EditText 的一半重叠，如下所示：所以我希望 EditText 自动向上滚动一点以完整显示自己。我试过 MainActivity.java onCreate() {

mEditText.scrollTo(0, mEditText.getTop());

尝试过

mEditText.scrollTo(0, mEditText.getTop() + 20); 
// to try if it will scroll up more in this way. it didn't.

但是当键盘出现时，编辑文本仍然像以前一样完全重叠了一半。我想我以错误的方式调用了该方法？

软键盘不与EditText重叠，但底部按钮重叠。当键盘显示时，是否可以通过编程方式将 EditText 滚动到按钮的正上方？

使用 paddingBottom 作为 ScrollView (LinearLayout) 的父级。如果按钮高度 = 50dp，将 paddingBottom="50dp" 设置为 LinearLayout。
