遇到的问题 
https://stackoverflow.com/questions/17630336/space-between-keyboard-and-edittext-in-android/25400043

1.edittext 试着加paddingBottom 是有用的 但是edittext字体sp ！= dp 不太好写布局
2.stateHidden|adjustResize 或者 adjustPan 选一种 前者是页面允许压缩  但是我的页面比较紧凑不太合适 所以只有用 adjustPan
3.接着想是不是监听键盘展开收起 试着ConstraintLayout外层添加滑动布局让其滑动到一定的高度呢？

ScrollView scrollto (0,height) 不管用 试了很久 忽然想到 是不是ScrollView android:layout_height="match_parent" 导致的？

又尝试了很久。。。
