大家好朋友我有一个自定义列表视图，其中我创建了两个xml用于显示列表视图，第二个用于列表视图中的每一行
我的代码和用户界面的一切都很好，但我的问题是让我们举个例子 当我在列表视图中显示8行并且我在第一行中单击按钮/组件然后自动第5个也被调用意味着onClick事件应用于第1和第5行组件我不知道如何解决这个问题我知道有傻错误，请你帮我提前谢谢
此处是 customAdapter
的代码public CustomAdapter(Activity a, ArrayList<?> d) {
/********** Take passed values **********/
activity = a;
data = d;
/*********** Layout inflator to call external xml layout () **********************/
inflater = (LayoutInflater) activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
/******** What is the size of Passed Arraylist Size ************/
public int getCount() {
if (data.size() <= 0)
return 1;
return data.size();
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
@Override
public int getViewTypeCount() {
if (getCount() != 0)
return getCount();
return 1;
}
/********* Create a holder to contain inflated xml file elements ***********/

答案 0 :(得分：0)
更改如下：从final ViewHolder holder;中删除getView()
然后改变这个：
public static class ViewHolder {
public int pos;
public Button btnLike;
public Button btnVoiceComment;
public Button btnShare;
public ImageButton ibMore;
public ImageButton ibPlayAudio;
public ImageView ivPostImage;
public ProgressWheel pw_two;
public TextView tvLocation, tvListens, tvMessage;
void setPosition(int position){
this.pos=position;
}
int getPosition(){
return pos;
}
}
创建 newView 方法，并从(convertView == null)
void newView(int position, View convertView, ViewGroup parent){
vi = inflater.inflate(R.layout.list_row_new, null);
final ViewHolder holder = new ViewHolder();
/******** View Holder Object to contain tabitem.xml file elements ************/
holder.setPosition(position);
holder.btnLike = (Button) vi.findViewById(R.id.list_row_btn_like);
holder.btnVoiceComment = (Button) vi
.findViewById(R.id.list_row_btn_voicecomment);
holder.ibMore = (ImageButton) vi
.findViewById(R.id.list_row_imgbtn_more);
holder.btnShare = (Button) vi
.findViewById(R.id.list_row_imgbtn_share);
holder.ivPostImage = (ImageView) vi
.findViewById(R.id.list_row_iv_post);
holder.ibPlayAudio = (ImageButton) vi
.findViewById(R.id.list_row_ib_play);
holder.tvMessage = (TextView) vi.findViewById(R.id.list_row_tv_msg);
holder.tvListens = (TextView) vi
.findViewById(R.id.list_row_tv_listencount);
holder.tvLocation = (TextView) vi
.findViewById(R.id.list_row_tv_city);
holder.pw_two = (ProgressWheel) vi
.findViewById(R.id.progressBarTwo);
/************ Set holder with LayoutInflater ************/
vi.setTag(holder);
}
也要小心改变
if (convertView == null) {
newView(position,convertview,parent);
}
else{
if(holder.getPosition()!=position)
newView(position,convertview,parent);
else
holder = (ViewHolder) vi.getTag();
}
其他一切都保持不变。
让我知道它是否有效。
