转载：使用ListView的Fragment

使用ListView的Fragment

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代码  

1. <?xmlversion="1.0"encoding="utf-8"?>

2. <LinearLayoutxmlns:android="http://schemas.android.com/apk/res/android"

3. android:layout_width="match_parent"

4. android:layout_height="match_parent"

5. android:orientation="vertical">

6. <TextView

7. android:layout_width="fill_parent"

8. android:layout_height="wrap_content"

9. android:gravity="center"

10. android:text="Titles"

11. />

13. <ListView

14. android:id="@id/android:list"

15. android:layout_width="fill_parent"

16. android:layout_height="wrap_content"

17. ></ListView>

19. </LinearLayout>

2)新建Fragment继承自ListFragment，命名为Fragment1。

Java代码  

1. import java.util.ArrayList;  

2. import java.util.HashMap;  

3. import java.util.List;  

4. import java.util.Map;  

6. import android.app.Activity;  

7. import android.os.Bundle;  

8. import android.support.v4.app.ListFragment;  

9. import android.util.Log;  

10. import android.view.LayoutInflater;  

11. import android.view.View;  

12. import android.view.ViewGroup;  

13. import android.widget.ListView;  

14. import android.widget.SimpleAdapter;  

15. import android.widget.TextView;  

16. import android.widget.Toast;  

18. /**

19. * @描述 在Fragment中要使用ListView，就要用ListFragment

20. * */

21. publicclass Fragment1 extends ListFragment   {  

23. private String TAG = Fragment1.class.getName();  

24. private ListView list ;  

25. private SimpleAdapter adapter;  

27. /**

28.     * @描述 在onCreateView中加载布局

29.     * */

30. @Override

31. public View onCreateView(LayoutInflater inflater, ViewGroup container,  

32.            Bundle savedInstanceState) {  

33.        View view = inflater.inflate(R.layout.fragment1, container,false);  

34.        list = (ListView) view.findViewById(android.R.id.list);  

35.        Log.i(TAG, "--------onCreateView");  

36. return view;  

37.    }  

39. @Override

40. publicvoid onCreate(Bundle savedInstanceState) {  

41. super.onCreate(savedInstanceState);  

42.        b = savedInstanceState;  

43.        Log.i(TAG, "--------onCreate");  

44.        String[] list = {"Class 1","Class 2","class 3","Class 4","Class 5"};  

45.        adapter = new SimpleAdapter(getActivity(), getData(list), R.layout.item_list, new String[]{"title"}, newint[]{R.id.title});  

46.        setListAdapter(adapter);  

48.    }  

50. @Override

51. publicvoid onListItemClick(ListView l, View v, int position, long id) {  

52. super.onListItemClick(l, v, position, id);  

54.        System.out.println(l.getChildAt(position));  

55.        HashMap<String, Object> view= (HashMap<String, Object>) l.getItemAtPosition(position);  

56.        System.out.println(view.get("title").toString()+"+++++++++title");  

61.        Toast.makeText(getActivity(), TAG+l.getItemIdAtPosition(position), Toast.LENGTH_LONG).show();  

62.        System.out.println(v);  

64.        System.out.println(position);  

67.    }  

72. private List<? extends Map<String, ?>> getData(String[] strs) {  

73.        List<Map<String ,Object>> list = new ArrayList<Map<String,Object>>();  

75. for (int i = 0; i < strs.length; i++) {  

76.            Map<String, Object> map = new HashMap<String, Object>();  

77.            map.put("title", strs[i]);  

78.            list.add(map);  

80.        }  

82. return list;  

83.    }  

85. @Override

86. publicvoid onActivityCreated(Bundle savedInstanceState) {  

87. super.onActivityCreated(savedInstanceState);  

88.        Log.i(TAG, "--------onActivityCreated");  

90.    }  

92. @Override

93. publicvoid onAttach(Activity activity) {  

94. super.onAttach(activity);  

95.        Log.i(TAG, "----------onAttach");  

96.    }  

98. }  

3)新建Activity，继承自FragmentActivity，将Fragment添加到Activity中。命名为FragmentsActivity。

Java代码  

1. publicclass FragmentsActivity extends FragmentActivity {  

3. @Override

4. protectedvoid onCreate(Bundle savedInstanceState) {  

5. super.onCreate(savedInstanceState);  

6.        setContentView(R.layout.activity_fragments);  

7.        Display display = getWindowManager().getDefaultDisplay();  

8.        Fragment1 f1 = new Fragment1();  

9.        FragmentManager manager  = getSupportFragmentManager();  

10.        manager.beginTransaction().add(R.id.fragments, f1).commit();  

14.    }  

16. @Override

17. publicboolean onCreateOptionsMenu(Menu menu) {  

18. // Inflate the menu; this adds items to the action bar if it is present.

19.        getMenuInflater().inflate(R.menu.fragments, menu);  

20. returntrue;  

21.    }  

23. }
