listview中添加Button后,Button能够功能不完全相同吗?
RT,我想用listview+Button,从网上找到了代码,但是不知道如何修改使到button有区别.
例如一些例子中 list.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) { }}
这样就可以有个位置的参数arg2来区别按钮,我可以把整个作为参数来传送区别不同按钮的功能;


但是当重写Adapter后,如何区别onClick事件呢?

谢谢,刚刚接触一知半解,麻烦了=,=

代码如下
package cn.LogDemo;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import android.util.Log;
import android.widget.BaseAdapter;
import android.view.LayoutInflater;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.*;

import android.widget.ListView;
import android.app.ListActivity;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.widget.ImageView;
import android.content.Context;
import android.view.ViewGroup;


public class testlist extends ListActivity {
public ViewHolder holder = null;


private List<Map<String, Object>> mData;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mData = getData();
MyAdapter adapter = new MyAdapter(this);
setListAdapter(adapter);
}

private List<Map<String, Object>> getData() {
List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();

Map<String, Object> map = new HashMap<String, Object>();
map.put("title", "G1");
map.put("info", "google 1");
map.put("img", R.drawable.icon);
list.add(map);

map = new HashMap<String, Object>();
map.put("title", "G2");
map.put("info", "google 2");
map.put("img", R.drawable.icon);
list.add(map);

map = new HashMap<String, Object>();
map.put("title", "G3");
map.put("info", "google 3");
map.put("img", R.drawable.icon);
list.add(map);

return list;
}

// ListView 中某项被选中后的逻辑
@Override
protected void onListItemClick(ListView l, View v, int position, long id) {

Log.v("MyListView4-click", (String)mData.get(position).get("title"));
}

/**
* listview中点击按键弹出对话框
*/
public void showInfo(){
new AlertDialog.Builder(this)
.setTitle("我的listview")
.setMessage("介绍...")
.setPositiveButton("确定", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
}
})
.show();

}

public final class ViewHolder{
public ImageView img;
public TextView title;
public TextView info;
public Button viewBtn;
}


public class MyAdapter extends BaseAdapter{

private LayoutInflater mInflater;


public MyAdapter(Context context){
this.mInflater = LayoutInflater.from(context);
}

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


public Object getItem(int arg0) {
// TODO Auto-generated method stub
return null;
}


public long getItemId(int arg0) {
// TODO Auto-generated method stub
return 0;
}

public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
holder=new ViewHolder();

convertView = mInflater.inflate(R.layout.testlist, null);
holder.img = (ImageView)convertView.findViewById(R.id.img);
holder.title = (TextView)convertView.findViewById(R.id.title);
holder.info = (TextView)convertView.findViewById(R.id.info);
holder.viewBtn = (Button)convertView.findViewById(R.id.view_btn);
convertView.setTag(holder);

}else {

holder = (ViewHolder)convertView.getTag();
}
holder.img.setBackgroundResource((Integer)mData.get(position).get("img"));
holder.title.setText((String)mData.get(position).get("title"));
holder.info.setText((String)mData.get(position).get("info"));

holder.viewBtn.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
showInfo();
//就是这里,如何不是用这个函数而是用其他的,怎么使他们有区别呢,只有能够区别开就行~!~
}
});


return convertView;
}

}
}


布局:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ImageView android:id="@+id/img"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="5px"/>
<LinearLayout android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView android:id="@+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#FFFFFFFF"
android:textSize="22px" />
<TextView android:id="@+id/info"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#FFFFFFFF"
android:textSize="13px" />
</LinearLayout>
<Button android:id="@+id/view_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="test"
android:layout_gravity="bottom|right" />
</LinearLayout>

譬如,我要把每个button左边的title或者info通过Intent传到下一个activity,该如何做呢?

谢谢指导

[解决办法]
不好意思看错了。以为是onItemClick里面的函数。

如果是Button里的，可以用相同的方法setTag ..后面部分的代码可以改成这样

public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
holder=new ViewHolder();
convertView = mInflater.inflate(R.layout.testlist, null);
holder.img = (ImageView)convertView.findViewById(R.id.img);
holder.title = (TextView)convertView.findViewById(R.id.title);
holder.info = (TextView)convertView.findViewById(R.id.info);
holder.viewBtn = (Button)convertView.findViewById(R.id.view_btn);
holder.viewBtn.setTag((String)mData.get(position).get("title"));

convertView.setTag(holder);

}else {

holder = (ViewHolder)convertView.getTag();
}
holder.img.setBackgroundResource((Integer)mData.get(position).get("img"));
holder.title.setText((String)mData.get(position).get("title"));
holder.info.setText((String)mData.get(position).get("info"));

holder.viewBtn.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
//showInfo();
//就是这里,如何不是用这个函数而是用其他的,怎么使他们有区别呢,只有能够区别开就行~!~
String title=(String)v.getTag();

//处理
}
});
