fragment中自定义listFragment不显示，程序闪退

fragment中自定义listFragment不显示，程序闪退
这是fragment的代码：
package com.example.date4_23;

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

import android.support.v4.app.ListFragment;
import android.content.Context;
import android.os.Bundle;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.TextView;

public class fragment1 extends ListFragment {

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

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    View v = inflater.inflate(R.layout.fragment1, container, false);

    Log.v("huahua", "fragment1-->onCreateView()");

// ViewGroup p = (ViewGroup) mMainView.getParent();
// if (p != null) {
// p.removeAllViewsInLayout();
// Log.v("huahua", "fragment1-->移除已存在的View");
// }

    return v;
}

@Override
public void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub

    super.onCreate(savedInstanceState);
    data = getDate();
    Myadapter adapter = new Myadapter(getActivity());
    setListAdapter(adapter);
    Log.v("huahua", "fragment1-->onCreate()");

}

private List<Map<String, Object>> getDate() {

    List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();
    Map<String, Object> map = new HashMap<String, Object>();
    map.put("img", "img1");
    map.put("title", "No.1");
    map.put("info", "This is raw No.1");
    list.add(map);

    map = new HashMap<String, Object>();
    map.put("img", "img2");
    map.put("title", "No.2");
    map.put("info", "This is raw No.2");
    list.add(map);

    return list;
}

static class ViewHolder{
    public ImageView img;
    public TextView title;
    public TextView info;
}

public class Myadapter extends BaseAdapter{

    private LayoutInflater mInflater = null;

    private Myadapter(Context context){
        this.mInflater = LayoutInflater.from(context);
    }

    @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) {

        Log.v("getView", "===========================getView=================");

        ViewHolder holder = null;
        holder = new ViewHolder();

        if(convertView == null)
        {

            convertView = mInflater.inflate(R.layout.list_item, 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);

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

        return convertView;
    }

}

}

这是布局文件：
fragment1.xml:
<?xml version="1.0" encoding="utf-8"?>
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#ffffff"
android:orientation="vertical" >

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

item的布局：
list_item.xml:
<?xml version="1.0" encoding="utf-8"?>
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >

<ImageView
    android:id="@+id/img"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_margin="5dp" />

<LinearLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="20sp" />

    <TextView
        android:id="@+id/info"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="14sp" />
</LinearLayout>

Logcat报错：

解决方案

 <ListView
    android:id="@+id/android:list"  改成@id/android:list
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" >
</ListView>

解决方案二：

android:id="@+id/android:list"
改为
android:id="@+id/list"

解决方案三：

我也是同样的问题，求解

解决方案四：

<include android:id="@+id/list_fragment" layout="@android:layout/list_content" />

    直接包含这个算了，好像内部的ID无法设置
