public class SearchBuilder {
        private LinearLayout search_bar;
        private TextView hint;
        public SearchBuilder(Activity context){
            search_bar = (LinearLayout) context.findViewById(R.id.search_bar_id);
            hint = (TextView) context.findViewById(R.id.search_bar_text);
        }
    
        public SearchBuilder(View context){
            search_bar = (LinearLayout) context.findViewById(R.id.search_bar_id);
            hint = (TextView) context.findViewById(R.id.search_bar_text);
        }
        //搜索按钮监听
        public SearchBuilder QueryOnListener(View.OnClickListener listener){
            if (search_bar.getVisibility() == View.VISIBLE){
                search_bar.setOnClickListener(listener);
            }
            return this;
        }
    
        //设置提示内容
        public SearchBuilder setHintText(String hintText){
            if (hint.getVisibility() == View.VISIBLE){
                hint.setText(hintText);
