Fragment对应的布局文件

<span style="font-size:18px;"><?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" >    <!--    android:id="@id/android:list"    Fragment  继承的是ListFragment  那么 id  就要固定的      -->    <ListView         android:id="@+id/android:list"        android:layout_width="match_parent"        android:layout_height="match_parent"/> </LinearLayout></span>

Fragment对应的逻辑代码文件

<span style="font-size:18px;">package com.example.day12_listfragment;import java.util.ArrayList;import java.util.List;import android.annotation.SuppressLint;import android.app.ListFragment;import android.os.Bundle;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.ArrayAdapter;import android.widget.ListView;import android.widget.Toast;@SuppressLint("NewApi") public class Listfragment extends ListFragment{List<String> list;@Overridepublic View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {list=new ArrayList<String>();for(int i=0;i<10;i++){list.add("You are beautiful!"+" "+i);}ArrayAdapter<String> adapter=new ArrayAdapter<String>(getActivity(),android.R.layout.simple_list_item_1,list);setListAdapter(adapter);View view=inflater.inflate(R.layout.list_fragment,container,false);return view;}@Overridepublic void onListItemClick(ListView l, View v, int position, long id) {super.onListItemClick(l, v, position, id);Toast.makeText(getActivity(),list.get(position), 0).show();}}</span>

主布局文件

<span style="font-size:18px;"><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=".MainActivity" >    <fragment        android:id="@+id/fg"        android:name="com.example.day12_listfragment.Listfragment"        android:layout_width="match_parent"        android:layout_height="wrap_content"        /></RelativeLayout></span>

主逻辑代码文件不需写代码
