Android软键盘遮住DialogFragment怎么解决

Question

弹出一个底部DialogFragment，里面包含TextView，但是点击TextView后软键盘会遮挡内容。
想要的效果是软键盘弹出来时候，整个DialogFragment是顶在软键盘上方，如下图。

P.S：请直接粘代码，咋们不谈理论。

public class Popup extends DialogFragment {

...............

@Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        root = inflater.inflate(mItemId, null);

        final Dialog dialog = getDialog();

        Window window = dialog.getWindow();
        WindowManager.LayoutParams lp = window.getAttributes();

        //取消标题
        window.requestFeature(Window.FEATURE_NO_TITLE);
        //去掉dialog默认的padding
        window.getDecorView().setPadding(0, 0, 0, 0);
        //取消设置弹窗自带的背景颜色
        window.setBackgroundDrawableResource(R.color.transparent);
        //设置导航栏颜
        window.setNavigationBarColor(Color.TRANSPARENT);
        //内容扩展到导航栏
        window.setType(WindowManager.LayoutParams.TYPE_APPLICATION_PANEL);

        //设置是否可关闭
        dialog.setCancelable(mCancelable);
        //设置没有标题
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);

        //设置Dialog的宽高
        lp.width = widthType;
        lp.height = heightType;
        //设置Dialog的位置在哪里
        lp.gravity = gravityType;

        ...................

        return root;
    }
}

将题主自定义布局替换为如下Dialog的布局. show（）的时候延迟100毫秒显示。
