android - 从 Custom ListView 中找出点击了哪个按钮

Question

在我的应用程序中，T 有带有 2 个按钮的自定义 ListView。现在我想要的是当用户单击 ListView 中的特定按钮时，将调用一个异步任务，该任务将少量参数发送到服务器。参数来自 ArrayList .现在我如何知道从 ListView 中单击了哪个按钮，以及在那个特定位置应该从 ArrayList 发送相同的数据。

public class SearchJobsCustomList extends BaseAdapter implements View.OnClickListener {
    Context c;
    ArrayList<HashMap<String, String>> data;

    HashMap<String, String> resultp = new HashMap<String, String> ();


    public SearchJobsCustomList(Context c, ArrayList<HashMap<String, String>> data) {
        super ();
        this.c = c;
        this.data = data;


    }

    @Override
    public int getCount() {
        return data.size ();
    }

    @Override
    public Object getItem(int i) {
        return null;
    }

    @Override
    public long getItemId(int i) {
        return 0;
    }

    @Override
    public View getView(int i, View view, ViewGroup viewGroup) {


        if (view == null) {
            view = LayoutInflater.from (c).inflate (R.layout.custom_search_jobs_lists, viewGroup, false);
            resultp = data.get (i);
            view.setTag (resultp);
            TextView JobCode = (TextView) view.findViewById (R.id.tv_job_code);

Answer 1

你可以像下面那样做，

-首先在 Button 初始化之后，在 getView() 中为您的 Button 设置标签，

bestCandidate.setTag(i);

然后在onClick方法中，你可以通过下面的操作得到列表行位置的Button标签，

 @Override
    public void onClick(View view) {

        switch (view.getId ()){
            case R.id.bt_best_candidates:

            Toast.makeText(getActivity(), view.getTag()+" is clicked", Toast.LENGTH_SHORT).show();
            BestCandidateDisplay display=new BestCandidateDisplay ();
            display.execute ();

        }

    }
