点击ListView中某个Item按钮，并且修改这个item的内容

使用接口回调，代码如下：

布局代码：

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.example.demo.MainActivity" >


    <ListView
        android:id="@+id/listView"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" ></ListView>


</RelativeLayout>

item布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >
    <TextView
        android:id="@+id/text"
        android:layout_width="fill_parent"
        android:layout_gravity="center_vertical"
        android:layout_height="40dp" />


</LinearLayout>

adapter代码：

package com.example.demo;


import java.util.ArrayList;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;


public class ListViewAdapter extends BaseAdapter {
private Context context;
private ArrayList<String> data = new ArrayList<String>();
private ListViewInterface ListViewInterface;


public ListViewAdapter(Context context, ArrayList<String> data, ListViewInterface listViewInterface) {
super();
this.context = context;
this.data = data;
this.ListViewInterface = listViewInterface;
}


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


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


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


@Override
public View getView(final int position, View convertView, ViewGroup parent) {
Holder holder = null;
String textString = data.get(position);
if (convertView == null) {
LayoutInflater inflater = LayoutInflater.from(context);
convertView = inflater.inflate(R.layout.listview_item, null);
holder = new Holder();
holder.text = (TextView) convertView.findViewById(R.id.text);
convertView.setTag(holder);
}
holder = (Holder) convertView.getTag();
holder.text.setText(textString);
holder.text.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View arg0) {
ListViewInterface.back(position,"我被修改了！！！！");

}
});
return convertView;
}


class Holder {
TextView text;
}


public interface ListViewInterface {
public void back(int position,String text);
}


}

activity代码：

package com.example.demo;


import java.util.ArrayList;


import com.example.demo.ListViewAdapter.ListViewInterface;


import android.app.Activity;
import android.os.Bundle;
import android.widget.ListView;


public class MainActivity extends Activity {
private ListView listView;
private ArrayList<String> data = new ArrayList<String>();
private ListViewAdapter adapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
setData();
listView = (ListView) findViewById(R.id.listView);
adapter = new ListViewAdapter(this, data, listViewInterface);
listView.setAdapter(adapter);
}

public void setData(){
for (int i = 0; i < 5; i++) {
data.add(new String("data"+i));
}
}

ListViewInterface listViewInterface = new ListViewInterface() {

@Override
public void back(int position,String text) {
data.set(position, new String(text));
adapter.notifyDataSetChanged();

}
};


}
