Android UI教程 - Android ListFragment

下面的代码显示了如何使用ListFragment。列表片段是包含ListView的片段。

例子

主布局文件

<?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" >

 <fragment
    android:name="com.java2s.ListFragmentExample.Fragment1"
    android:id="@+id/fragment1"
    android:layout_weight="0.5"
    android:layout_width="0dp"
    android:layout_height="200dp" />

 <fragment
    android:name="com.java2s.ListFragmentExample.Fragment1"
    android:id="@+id/fragment2"
    android:layout_weight="0.5"
    android:layout_width="0dp"
    android:layout_height="300dp" />

</LinearLayout>

填充fragment1.xml如下:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   android:orientation="vertical"
   android:layout_width="fill_parent"
   android:layout_height="fill_parent">
   <ListView
       android:id="@id/android:list"
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       android:layout_weight="1"
       android:drawSelectorOnTop="false"/>
</LinearLayout>

Fragment1.java的Java代码

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;
//  w ww . j  ava 2 s.  co  m
public class Fragment1 extends ListFragment {
    String[] myValue = {"XML","HTML","CSS","Javascript"};

    @Override
    public View onCreateView(LayoutInflater inflater,
    ViewGroup container, Bundle savedInstanceState) {
        return inflater.inflate(R.layout.fragment1, container, false);
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setListAdapter(new ArrayAdapter<String>(getActivity(),
            android.R.layout.simple_list_item_1, myValue));
    }

    public void onListItemClick(ListView parent, View v,
    int position, long id)
    {
        Toast.makeText (getActivity(),
            "You have selected " + myValue [position],
            Toast.LENGTH_SHORT).show();
    }

}
