Android 小技巧之 Recyclerview 选中效果

1. 在 DataBean 中添加一个参数

private boolean isSelected;

        public boolean getSelected() {
            return isSelected;
        }

        public void setSelected(boolean selected) {
            isSelected = selected;
        }

2. adpter 中逻辑代码

LinearLayout layout = helper.getView(R.id.ll_item_gift);

        final int position = helper.getAdapterPosition();
        boolean selected = getData().get(position).getSelected();
        if (selected) {
            layout.setBackgroundResource(R.drawable.shape_sel_gift);
        } else {
            layout.setBackgroundResource(R.drawable.shape_nor_gift);
        }
       helper.addOnClickListener(R.id.ll_item_gift);

3. Activity 中逻辑代码

mAdapter.setOnItemChildClickListener(new BaseQuickAdapter.OnItemChildClickListener() {
            @Override
            public void onItemChildClick(BaseQuickAdapter adapter, View view, int position) {
                for (GiftGoodsBean.DataBean homeBean1 : mTypeData) {
                    homeBean1.setSelected(false);
                }
                mTypeData.get(position).setSelected(true);
                mAdapter.notifyDataSetChanged();
                menuNo = mTypeData.get(position).getMenuNo();

            }
        });
