API LEVEL 11
1.使用ListFragment可实现包含Listiew的Fragment
2.在Fragment的布局中必须包含id “@android:id/list”(在代码中则是list)的Listview
3.只能使用SimpleAdapter或者SimpleCursorAdapter作为适配器
4.直接使用ListFragment的setListAdapter()来设置适配器【不要给ListView设置】
5.ListView点击事件的监听,重写ListFragment的onListItemClick(ListView l, View v, int position, long id)方法
1)新建ListFragment的布局fragment1.xml
- <?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=“fill_parent”
- android:layout_height=“wrap_content”
- android:gravity=“center”
- android:text=“Titles”
- />
- <ListView
- android:id=“@id/android:list”
- android:layout_width=“fill_parent”
- android:layout_height=“wrap_content”
- ></ListView>
- </LinearLayout>
2)新建Fragment继承自ListFragment,命名为Fragment1。
- import java.util.ArrayList;
- import java.util.HashMap;
- import java.util.List;
- import java.util.Map;
- import android.app.Activity;
- import android.os.Bundle;
- import android.support.v4.app.ListFragment;
- import android.util.Log;
- import android.view.LayoutInflater;
- import android.view.View;
- import android.view.ViewGroup;
- import android.widget.ListView;
- import android.widget.SimpleAdapter;
- import android.widget.TextView;
- import android.widget.Toast;
- /**
- * @描述 在Fragment中要使用ListView,就要用ListFragment
- * */
- public class Fragment1 extends ListFragment {
- private String TAG = Fragment1.class.getName();
- private ListView list ;
- private SimpleAdapter adapter;
- /**
- * @描述 在onCreateView中加载布局
- * */
- @Override
- public View onCreateView(LayoutInflater inflater, ViewGroup container,
- Bundle savedInstanceState) {
- View view = inflater.inflate(R.layout.fragment1, container,false);
- list = (ListView) view.findViewById(android.R.id.list);
- Log.i(TAG, “——–onCreateView”);
- return view;
- }
- @Override
- public void onCreate(Bundle savedInstanceState) {
- super.onCreate(savedInstanceState);
- b = savedInstanceState;
- Log.i(TAG, “——–onCreate”);
- String[] list = {“Class 1”,“Class 2”,“class 3”,“Class 4”,“Class 5”};
- adapter = new SimpleAdapter(getActivity(), getData(list), R.layout.item_list, new String[]{“title”}, new int[]{R.id.title});
- setListAdapter(adapter);
- }
- @Override
- public void onListItemClick(ListView l, View v, int position, long id) {
- super.onListItemClick(l, v, position, id);
- System.out.println(l.getChildAt(position));
- HashMap<String, Object> view= (HashMap<String, Object>) l.getItemAtPosition(position);
- System.out.println(view.get(“title”).toString()+“+++++++++title”);
- Toast.makeText(getActivity(), TAG+l.getItemIdAtPosition(position), Toast.LENGTH_LONG).show();
- System.out.println(v);
- System.out.println(position);
- }
- private List<? extends Map<String, ?>> getData(String[] strs) {
- List<Map<String ,Object>> list = new ArrayList<Map<String,Object>>();
- for (int i = 0; i < strs.length; i++) {
- Map<String, Object> map = new HashMap<String, Object>();
- map.put(“title”, strs[i]);
- list.add(map);
- }
- return list;
- }
- @Override
- public void onActivityCreated(Bundle savedInstanceState) {
- super.onActivityCreated(savedInstanceState);
- Log.i(TAG, “——–onActivityCreated”);
- }
- @Override
- public void onAttach(Activity activity) {
- super.onAttach(activity);
- Log.i(TAG, “———-onAttach”);
- }
- }
3)新建Activity,继承自FragmentActivity,将Fragment添加到Activity中。命名为FragmentsActivity。
- public class FragmentsActivity extends FragmentActivity {
- @Override
- protected void onCreate(Bundle savedInstanceState) {
- super.onCreate(savedInstanceState);
- setContentView(R.layout.activity_fragments);
- Display display = getWindowManager().getDefaultDisplay();
- Fragment1 f1 = new Fragment1();
- FragmentManager manager = getSupportFragmentManager();
- manager.beginTransaction().add(R.id.fragments, f1).commit();
- }
- @Override
- public boolean onCreateOptionsMenu(Menu menu) {
- // Inflate the menu; this adds items to the action bar if it is present.
- getMenuInflater().inflate(R.menu.fragments, menu);
- return true;
- }
- }
