ListView 中添加按钮，动态删除添加ItemView的操作（转）

要实现添加按钮的操作，必须自定义Adapter，使用Button View的setTag()方法，将Button所属的位置设置到tag当中
要实现动态添加删除ItemView的操作，必须首先调整调整Adapter所绑定的数据源，然后调用Adapter的notifyDataSetChanged()方法

以下为实现的一个实例

package com.jason.joysmsyd;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import android.app.ListActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.view.Window;
import android.view.View.OnClickListener;
import android.widget.BaseAdapter;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;

public class SendMain extends ListActivity implements OnClickListener{

	Button buttonMessage,buttonContact,buttonHistory;
	EditText textMessage;
	
	List<Map<String,String>> contacts = new ArrayList<Map<String,String>>();
	
	
	
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.onCreate(savedInstanceState);
		this.requestWindowFeature(Window.FEATURE_NO_TITLE);
		
		this.setContentView(R.layout.layout_send);
		
		buttonMessage = (Button) this.findViewById(R.id.ButtonMessage);
		buttonContact = (Button) this.findViewById(R.id.ButtonContact);
		buttonHistory = (Button) this.findViewById(R.id.ButtonHistory);
		
		textMessage = (EditText)this.findViewById(R.id.EditTextMessage);
		textMessage.setText(this.getIntent().getExtras().getString("message"));
	
	}

	public void onClick(View v) {
		// TODO Auto-generated method stub
		switch(v.getId()){
		case R.id.ButtonMessage:
			this.finish();
			break;
		case R.id.ButtonContact:
		{
			Intent intent = new Intent();
			intent.setAction("com.jason.action.contact");
			this.startActivityForResult(intent, 0);
		}
			break;
		case R.id.ButtonHistory:
		{
			Intent intent = new Intent();
			intent.setAction("com.jason.action.history");
			this.startActivityForResult(intent, 1);
		}
			break;
		}
		
	}

	
	protected void onActivityResult(int requestCode, int resultCode, Intent data) {
		// TODO Auto-generated method stub
		super.onActivityResult(requestCode, resultCode, data);
		 if (requestCode == 0 && resultCode == RESULT_OK) {
			this.getcontactFromString(data.getExtras().getString(
					UserSelectActivity.RETURN_LIST));
			bindDataToList();
		}
	}

	private void getcontactFromString(String data) {
		if (data == null || data.length() == 0) {
			return;
		}

		
		String[] arrayContact = data.split("#");
		for (String singleContact : arrayContact) {
			if (singleContact != null && singleContact.length() > 0) {
				String[] props = singleContact.split(":");
				if (props.length == 2) {
					Map<String,String> contact = new HashMap<String,String>();
					contact.put("name", props[0]);
					contact.put("phone", props[1]);
					contacts.add(contact);

				}
			}

		}
		
	}
	
	private void bindDataToList(){
		this.setListAdapter(new MyAdapter());
	}
	
	public class MyAdapter extends BaseAdapter{

		public int getCount() {
			// TODO Auto-generated method stub
			return contacts.size();
		}

		public Object getItem(int position) {
			// TODO Auto-generated method stub
			return contacts.get(position);
		}

		public long getItemId(int position) {
			// TODO Auto-generated method stub
			return position;
		}


		public View getView(int position, View convertView, ViewGroup parent) {
			// TODO Auto-generated method stub
			LayoutInflater inflater = SendMain.this.getLayoutInflater();
			 final View view = inflater.inflate(R.layout.layout_user_item, null);
			 final TextView textPhone = (TextView) view.findViewById(R.id.text1);
			 final TextView textName = (TextView) view.findViewById(R.id.text2);
			 Button button = (Button)view.findViewById(R.id.buttonDelete);
			
			 textPhone.setText(contacts.get(position).get("phone"));
			 textName.setText(contacts.get(position).get("name"));
			 
			 button.setTag( position);
			 
			 button.setOnClickListener(new OnClickListener(){

				public void onClick(View v) {
					// TODO Auto-generated method stub
					int position = Integer.parseInt(v.getTag().toString());
					contacts.remove(position);
					MyAdapter.this.notifyDataSetChanged();
					
//					SendMain.this.getListView().refreshDrawableState();
				}});
			 
			 
			 
			
			return view;
		}
		
	}
}
