ListView中自定义Adapter出现的控件显示错乱现象的解决方案

自定义Adapter中，使用ViewHolder这样的写法应该是绝大多数人的选择，毕竟为了ListView的平滑感考虑。但是，恼人的是，这样的写法会造成listView在滑动中，会出现控件显示错乱的情况。

解决方案：

在else中添加一个方法，使viewholder中的控件状态恢复默认值即可。

public finalclassViewHolder {

      private TextView hphmTextView;

      private TextView hpzlTextView;

      private Button finishButton;

      private TextView drakeTextView;

      private TextView ligthTextView;

      private TextView zcTextView;

      private TextView sdTextView;

   }

@Override

      public View getView(int position, ViewconvertView, ViewGroup parent) {

         if (convertView == null) {

            viewHolder = new ViewHolder();

            convertView= layoutInflater.inflate(

                   R.layout.activity_lsdjcl_list_item2,null);

            viewHolder.hphmTextView = (TextView)convertView

                   .findViewById(R.id.txt_hphm);

            viewHolder.hpzlTextView = (TextView)convertView

                   .findViewById(R.id.txt_hpzl);

            viewHolder.drakeTextView = (TextView)convertView

                   .findViewById(R.id.brake);

            viewHolder.ligthTextView = (TextView)convertView

                   .findViewById(R.id.light);

            viewHolder.zcTextView = (TextView)convertView

                   .findViewById(R.id.txt_zc_state);

            viewHolder.sdTextView = (TextView)convertView

                   .findViewById(R.id.txt_sd_state);

            viewHolder.finishButton = (Button)convertView

                   .findViewById(R.id.btn_finish);

 

            convertView.setTag(viewHolder);

         }else{

            viewHolder = (ViewHolder)convertView.getTag();

            resetViewHolder(viewHolder);

         }

 //重新写的方法

private voidresetViewHolder(ViewHolder vh) {

      vh.finishButton.setVisibility(View.GONE);

   }
