通过onClickListener调用ListView项目onItemClick

Question

在“我的列表”中，我有一些带有按钮的项目，目前，每当我尝试单击该按钮时，它也会触发onItemClick。 下面的代码在getView内部

holder.btnAdd.setTag(tg);       
    holder.btnAdd.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            int id = v.getId();
            Toast.makeText(getParent().getActivity(), "clicked this button",Toast.LENGTH_LONG).show();
    });

这是onItemClick，它位于适配器之外。

HorizontalListView hlv = (HorizontalListView) view
            .findViewById(R.id.gallery);

    GalleryAdapter ga = new GalleryAdapter(offerItemDetailsFragment,
            result);
    ga.setListView(hlv);
    hlv.setAdapter(ga);
    hlv.setOnItemClickListener(new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> parent, View view,
                int position, long id) {
             RelatedOffer relOffer = (RelatedOffer) parent.getAdapter().getItem(position);
            ...
        }
    });

Answer 1

如果不使用带有内部可点击元素的列表，则不能使用OnItemClickListener 。 相反，尝试将OnClickListener添加到行的根布局中，然后在其中执行项目单击逻辑。

Answer 2

如果您的按钮在列表中，则尝试检索该按钮的ID，并对该按钮具有单击侦听器，或者如果您有一个自定义适配器，则在自定义适配器上为该按钮编写侦听器！

假设您的持有人如下

static class UserHolder {
  TextView textName;
  TextView textAddress;
  TextView textLocation;
  Button btnEdit;
  Button btnDelete;
 }

关于这个尝试写getView如下

@Override
 public View getView(int position, View convertView, ViewGroup parent) {
  View row = convertView;
  UserHolder holder = null;

  if (row == null) {
   LayoutInflater inflater = ((Activity) context).getLayoutInflater();
   row = inflater.inflate(layoutResourceId, parent, false);
   holder = new UserHolder();
   holder.textName = (TextView) row.findViewById(R.id.textView1);
   holder.textAddress = (TextView) row.findViewById(R.id.textView2);
   holder.textLocation = (TextView) row.findViewById(R.id.textView3);
   holder.btnEdit = (Button) row.findViewById(R.id.button1);
   holder.btnDelete = (Button) row.findViewById(R.id.button2);
   row.setTag(holder);
  } else {
   holder = (UserHolder) row.getTag();
  }
  User user = data.get(position);
  holder.textName.setText(user.getName());
  holder.textAddress.setText(user.getAddress());
  holder.textLocation.setText(user.getLocation());
  holder.btnEdit.setOnClickListener(new OnClickListener() {

   @Override
   public void onClick(View v) {
    // TODO Auto-generated method stub
    Log.i("Edit Button Clicked", "**********");
    Toast.makeText(context, "Edit button Clicked",
      Toast.LENGTH_LONG).show();
   }
  });
  holder.btnDelete.setOnClickListener(new OnClickListener() {

   @Override
   public void onClick(View v) {
    // TODO Auto-generated method stub
    Log.i("Delete Button Clicked", "**********");
    Toast.makeText(context, "Delete button Clicked",
      Toast.LENGTH_LONG).show();
   }
  });
  return row;

 }

这样您的自定义适配器可以看起来像

import java.util.ArrayList;
import android.app.Activity;
import android.content.Context;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.TextView;
import android.widget.Toast;

public class UserCustomAdapter extends ArrayAdapter<User> {
 Context context;
 int layoutResourceId;
 ArrayList<User> data = new ArrayList<User>();

 public UserCustomAdapter(Context context, int layoutResourceId,
   ArrayList<User> data) {
  super(context, layoutResourceId, data);
  this.layoutResourceId = layoutResourceId;
  this.context = context;
  this.data = data;
 }

 @Override
 public View getView(int position, View convertView, ViewGroup parent) {
  View row = convertView;
  UserHolder holder = null;

  if (row == null) {
   LayoutInflater inflater = ((Activity) context).getLayoutInflater();
   row = inflater.inflate(layoutResourceId, parent, false);
   holder = new UserHolder();
   holder.textName = (TextView) row.findViewById(R.id.textView1);
   holder.textAddress = (TextView) row.findViewById(R.id.textView2);
   holder.textLocation = (TextView) row.findViewById(R.id.textView3);
   holder.btnEdit = (Button) row.findViewById(R.id.button1);
   holder.btnDelete = (Button) row.findViewById(R.id.button2);
   row.setTag(holder);
  } else {
   holder = (UserHolder) row.getTag();
  }
  User user = data.get(position);
  holder.textName.setText(user.getName());
  holder.textAddress.setText(user.getAddress());
  holder.textLocation.setText(user.getLocation());
  holder.btnEdit.setOnClickListener(new OnClickListener() {

   @Override
   public void onClick(View v) {
    // TODO Auto-generated method stub
    Log.i("Edit Button Clicked", "**********");
    Toast.makeText(context, "Edit button Clicked",
      Toast.LENGTH_LONG).show();
   }
  });
  holder.btnDelete.setOnClickListener(new OnClickListener() {

   @Override
   public void onClick(View v) {
    // TODO Auto-generated method stub
    Log.i("Delete Button Clicked", "**********");
    Toast.makeText(context, "Delete button Clicked",
      Toast.LENGTH_LONG).show();
   }
  });
  return row;

 }

 static class UserHolder {
  TextView textName;
  TextView textAddress;
  TextView textLocation;
  Button btnEdit;
  Button btnDelete;
 }
}
