Fragment的简单使用

最近一直有点忙,刚刚看到一个朋友的留言提到Fragment中加载ListView的问题,这里写了一个非常简单的测试,至于对Fragment的增、删、改实现动态布局构建灵活的UI,以后有时间在讨论:

MainActivity:

package com.home.testfragment;

import java.util.ArrayList;
import java.util.List;

import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.widget.ArrayAdapter;
import android.widget.ListView;

public class MainActivity extends FragmentActivity {
	@Override
	protected void onCreate(Bundle arg0) {
		super.onCreate(arg0);
		setContentView(R.layout.main);
		ListView listView = (ListView) findViewById(R.id.fragment__first_list);
		List<String> list = new ArrayList<String>();
		list.add("张三");
		list.add("李四");
		list.add("王五");
		list.add("赵六");
		ArrayAdapter<String> adapter = new ArrayAdapter(this,
				android.R.layout.simple_list_item_1, list);
		listView.setAdapter(adapter);
	}
}

FirstFragment:

package com.home.testfragment;

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

public class FirstFragment extends Fragment {
	@Override
	public View onCreateView(LayoutInflater inflater, ViewGroup container,
			Bundle savedInstanceState) {
		return inflater.inflate(R.layout.fragment_first, container, false);
	}
}

main.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <fragment
        android:name="com.home.testfragment.FirstFragment"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:tag="@+id/main_fragment_first" />

</LinearLayout>

fragment_first:

<?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:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="测试fragment的简单使用"
        android:textSize="20sp" />

    <ListView
        android:id="@+id/fragment__first_list"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >
    </ListView>

</LinearLayout>

附上界面效果:
