//功能:点击一个按钮,显示出一个ListFragment,将ListFragment的内容给右边的Fragment显示出来 //MainActivity代码: public class MainActivity extends FragmentActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); } public void clickButton(View view) { FragmentTransaction transaction = getSupportFragmentManager() .beginTransaction(); transaction.add(R.id.center, new ListFragmentDemo(), "ListFragment"); transaction.commit(); } } //继承的是ListFragment,,ListFragmentDemo中代码 public class ListFragmentDemo extends ListFragment { private ArrayAdapter<String> adapter; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); List<String> list = new ArrayList<String>(); for (int i = 0; i < 30; i++) { list.add("mike嘿嘿嘿" + i); } adapter = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_list_item_1, list); setListAdapter(adapter); // ListFragment 的好处是不用创建一个Listview,由于它内含有ListView的布局,直接绑定 } // 并且也有监听事件 @Override public void onListItemClick(ListView l, View v, int position, long id) { super.onListItemClick(l, v, position, id); // 传值给另一个Fragment // 注意这里不是getSupportFragmentManager()了,这个V4版本才有 FragmentManager fragmentManager = getFragmentManager(); FragmentTransaction transaction = fragmentManager.beginTransaction(); ShowListFragment showListFragment = new ShowListFragment(); transaction.add(R.id.right, showListFragment, "ShowListFragment"); // 从ListFragment获取数据 // 这里须要用到适配器获取数据,最好定义全局 String name = adapter.getItem(position); Bundle bundle = new Bundle(); bundle.putString("name", name); showListFragment.setArguments(bundle); transaction.commit(); } } public class ShowListFragment extends Fragment { @Override public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { Bundle bundle = getArguments(); String name = bundle.getString("name"); TextView textView=new TextView(getActivity()); textView.setText(name); return textView; } } //主布局文件 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="horizontal" > <LinearLayout android:id="@+id/left" android:layout_width="0dp" android:layout_height="match_parent" android:layout_weight="1" android:background="#cccccc" android:orientation="vertical" > <Button android:id="@+id/bnt_show" android:layout_width="match_parent" android:layout_height="wrap_content" android:onClick="clickButton" android:text="显示" android:textSize="14sp" /> </LinearLayout> <LinearLayout android:id="@+id/center" android:layout_width="0dp" android:layout_height="match_parent" android:layout_weight="2" android:background="#AFEEEE" android:orientation="vertical" > </LinearLayout> <LinearLayout android:id="@+id/right" android:layout_width="0dp" android:layout_height="match_parent" android:layout_weight="2" android:background="#00FFFF" android:orientation="vertical" > </LinearLayout> </LinearLayout>
