code: public void hideEmojiLayout() {
          LayoutParams params = (LayoutParams) mContentLayout.getLayoutParams();
          params.height = 0;
          params.weight = 1;
          LayoutParams params2 = (LayoutParams) mEmojiLayout.getLayoutParams();
          params2.height = 0;
          params2.weight = 0;
          mEmojiLayout.setVisibility(GONE);
          isEmojiLayoutShow = false;
          requestLayout();
      }
docs: 恢复成默认就行了
