fragment、ListFragment使用ListView及自定义Listview等初始化操作

1.先说一下 从官方api中说fragment碎片中使用Listview有专门的 ListView碎片-> ListFragment 而不能继承Fragment

 官方api相关连接：http://developer.android.com/guide/components/fragments.html

2.不废话直接上代码，这是我项目种的代码 2.1版本同样适用

父类封装：

public class BaseListFragment extends ListFragment {
	public Map<String, String> map;
    public String tag = this.getClass().getSimpleName(); // tag 用于测试log用
	public Context context; // 存储上下文对象
	public Activity activity; // 存储上下文对象
	
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		context = getActivity();
		activity = getActivity();
	}
}

子类实现：

/**
 * 新闻分类页面
 * @author chen
 * @date 2012-12-18 下午5:48:02
 */
public class NewsFragment extends BaseListFragment {
	/** 请求url */
	private String url;
	/** ListView */
	private PullListView mListView;
//	/** 分页 */
//	private Page page = new Page();
	/** 商铺适配器 */
	private Adapter mAdapter = new Adapter(activity);;
	/** 集合数据 */
	public ArrayList<News> mListData;
	/** 是否重新加载 */
	private boolean isClear;
	
	private LayoutInflater mInflater;
	/** 新闻详细页面 url */
	private String detailUrl = C.http.http_news_detail;
	
	public NewsFragment(){}
	public NewsFragment(Context context, String url) {
		this.context = context;
		this.url = url;
		mListData = null;
	}
	
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		Log.i(tag, "onCreate");
	}
	
	// 加载多次
	public void onActivityCreated(Bundle savedInstanceState) {
		super.onActivityCreated(savedInstanceState);
		Log.i(tag, "onActivityCreated");
		mListView = (PullListView) getListView();//(ListView) activity.findViewById(android.R.id.list);
		if(mListData != null && mListData.size() > 0) {
			return;
		}
		
		mListData = new ArrayList<News>();
		setListAdapter(mAdapter);
		mListView.onRefreshComplete();
		mListView.setonRefreshListener(new OnRefreshListener() {
			public void onRefresh() {
				isClear = true;
				// 初始化数据
				AnsynHttpRequest.requestByGet(context, callbackData, R.string.http_news, url, true, true, true);
			}
		});
		// 初始化数据
		AnsynHttpRequest.requestByGet(context, callbackData, R.string.http_news, url, true, true, false);
	}

	// 加载多次
	@Override
	public View onCreateView(LayoutInflater inflater, ViewGroup container,
			Bundle savedInstanceState) {
		super.onCreateView(inflater, container, savedInstanceState);
		View view = inflater.inflate(R.layout.fragment_news_or_hotline, container, false);
		mInflater = inflater;
		Log.i(tag, "onCreateView");
		return view;
	}
	@Override
	public void onStart() {
		Log.i(tag, "onStart");
		super.onStart();
	}
	@Override
	public void onStop() {
		super.onStop();
		Log.i(tag, "onStop");
	}
	@Override
	public void onDestroy() {
		super.onDestroy();
		Log.i(tag, "onDestroy");
	}

layout 如下：里面引用的是网上找的自定义下拉上啦刷新 可自行去找

<?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="vertical" >

    <com.vv.apps.hua.app.base.view.PullListView
        android:id="@android:id/list"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:cacheColorHint="@color/transparent"
        android:divider="@null"
        android:dividerHeight="0dp"
        android:fastScrollEnabled="true"
        android:focusable="true"
         />

</LinearLayout>
