推荐答案
我已经通过在EditText上添加OnFocusChangeListener来解决此问题，如果它具有焦点-可以使用setExpanded方法折叠视图:
I've resolved this by adding OnFocusChangeListener to EditText and if it has focus - just collapse view with setExpanded method:
editText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
@Override
public void onFocusChange(final View v, boolean hasFocus) {
if (hasFocus) {
mAppBarLayout.setExpanded(false, true);
}
}
});
如果您希望每次在布局中放置其他EditText时都折叠CollapsingToolbarLayout，则应该为它们中的每个设置相同的OnFocusChangeListener.
If you want your CollapsingToolbarLayout be collapsed every time when your other EditText's from your layout get focused, then you should set the same OnFocusChangeListener to each of them.
