我自己经过测试的 包含 button 的 listView

package gyf.android;import gyf.function.MyAdapter1;import java.util.ArrayList;import java.util.HashMap;import java.util.Map;import android.app.Activity;import android.app.ListActivity;import android.os.Bundle;import android.view.View;import android.widget.ListView;import android.widget.Toast;public class g1 extends ListActivity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.listview); ListView listView=(ListView)findViewById(android.R.id.list); ArrayList<Map<String, Object>> dataList=new ArrayList<Map<String,Object>>(); for (int i = 0; i <6; i++) {Map<String, Object> map=new HashMap<String, Object>();map.put("username", "gyf");//map.put("changeButton", "change");dataList.add(map);} // 生成适配器的Item和动态数组对应的元素 MyAdapter1 listItemAdapter = new MyAdapter1( this, dataList,//数据源 R.layout.main,//ListItem的XML实现 //动态数组与ImageItem对应的子项 new String[] {"username"}, //ImageItem的XML文件里面的一个ImageView,两个TextView ID new int[] {R.id.g1_textView1} ); listView.setAdapter(listItemAdapter); } protected void onListItemClick(ListView l, View v, int position, long id) { // TODO Auto-generated method stub super.onListItemClick(l, v, position, id); l.getItemAtPosition(position); Toast.makeText(g1.this, "hello", Toast.LENGTH_SHORT).show(); } }

定义的适配器类

package gyf.function;import gyf.android.R;import gyf.android.g1;import java.util.ArrayList;import java.util.HashMap;import java.util.Map;import android.content.Context;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.view.View.OnClickListener;import android.widget.BaseAdapter;import android.widget.Button;import android.widget.TextView;import android.widget.Toast;public class MyAdapter1 extends BaseAdapter { private class buttonViewHolder { TextView appName; Button buttonClose; } ArrayList<Map<String, Object>> alist; LayoutInflater lInflater; buttonViewHolder bHolder; Context context; String[] strings; int[] i; public MyAdapter1(Context c,ArrayList<Map<String, Object>> AlList,int resouse,String[] from,int[] to){ context=c; alist=AlList; lInflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); strings=new String[from.length]; i=new int[to.length]; System.arraycopy(from, 0, strings, 0, from.length); System.arraycopy(to, 0, i, 0, to.length); }@Overridepublic int getCount() {// TODO Auto-generated method stubreturn alist.size();}@Overridepublic Object getItem(int position) {// TODO Auto-generated method stubreturn alist.get(position);}@Overridepublic long getItemId(int position) {// TODO Auto-generated method stubreturn position;}@Overridepublic View getView(int position, View convertView, ViewGroup parent) {// TODO Auto-generated method stub if (convertView != null) { bHolder = (buttonViewHolder) convertView.getTag(); } else { convertView = lInflater.inflate(R.layout.main, null); bHolder = new buttonViewHolder(); bHolder.appName = (TextView)convertView.findViewById(i[0]); bHolder.buttonClose = (Button)convertView.findViewById(R.id.g1_button1); convertView.setTag(bHolder); } HashMap<String, Object> appInfo = (HashMap<String, Object>)alist.get(position); if (appInfo != null) { String aname = (String) appInfo.get(strings[0]); // String buString = (String)appInfo.get(strings[1]); bHolder.appName.setText(aname); // bHolder.buttonClose.setText(buString); bHolder.buttonClose.setOnClickListener(new lvButtonListener(position)); } return convertView; } class lvButtonListener implements OnClickListener { private int position; lvButtonListener(int pos) { position = pos; } @Override public void onClick(View v) { int vid=v.getId(); if (vid == bHolder.buttonClose.getId()){ //alist.remove(position); alist.get(position).put(strings[0], "111"); MyAdapter1.this.notifyDataSetChanged(); //bHolder.appName.setText("lyx"); Toast.makeText(context, "world"+position, Toast.LENGTH_SHORT).show(); } } }}

界面布局：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="horizontal"> <ListView android:id="@id/android:list" android:layout_width="fill_parent" android:layout_height="fill_parent" /></LinearLayout>

item布局：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="horizontal" android:descendantFocusability="blocksDescendants"> <TextView android:layout_height="wrap_content" android:layout_weight="1" android:layout_width="wrap_content" android:text="@string/g1" android:gravity="center" android:id="@+id/g1_textView1"></TextView> <Button android:layout_height="wrap_content" android:text="Button" android:layout_width="wrap_content" android:layout_weight="1" android:focusable="false" android:id="@+id/g1_button1"></Button></LinearLayout>
