android - Android中键盘上方的电影recyclerview

Question

我有我的自定义 BottomSheetDialogFragment。在此对话框中，我有自定义的 edittext 和 recyclerview。我的目标是在显示时将 reyclerview 移动到键盘上方。这是我的自定义编辑文本代码

public class WrappedEditText extends android.support.v7.widget.AppCompatEditText {

public WrappedEditText(Context context) {
    super(context);
}

public WrappedEditText(Context context, AttributeSet attrs) {
    super(context, attrs);
}

public WrappedEditText(Context context, AttributeSet attrs, int defStyleAttr) {
    super(context, attrs, defStyleAttr);
}

@Nullable
private View wrapper;

@Nullable
public View getWrapper() {
    return wrapper;
}

@Override
public void getFocusedRect(Rect r) {
    if (wrapper != null) {
        wrapper.getFocusedRect(r);
        return;
    }
    super.getFocusedRect(r);
}

@Override
public boolean getGlobalVisibleRect(Rect r, Point globalOffset) {
    if (wrapper != null)
        return wrapper.getGlobalVisibleRect(r, globalOffset);
    return super.getGlobalVisibleRect(r, globalOffset);
}

public void setWrapper(@Nullable View wrapper) {
    this.wrapper = wrapper;
}

我正在使用这样的代码

 searchView.setWrapper(rootView);
    searchView.setOnFocusChangeListener((view1, b) -> {
        if(searchView.getWrapper()==null)
            searchView.setWrapper(rootView);
    });

rootView 是 xml 文件中的主视图。此代码仅第一次运行完美，但当用户关闭键盘然后再次打开时，此代码不起作用。有什么办法可以解决这个问题吗？或者这是一个正确的解决方案？谢谢
