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
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 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; } } }原文链接：http://www.cnblogs.com/qzxia/archive/2010/11/29/1890959.html
