import android.widget.Toast;public class CenterListFragment extends ListFragment {private ArrayAdapter<String> adapter;private List<String> data;private FragmentManager manager;private FragmentTransaction transaction;@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);data = new ArrayList<String>();for (int i = 0; i < 11; i++) {data.add("data" + i);}manager = getFragmentManager();adapter = new ArrayAdapter<String>(getActivity(),android.R.layout.simple_list_item_1, data);setListAdapter(adapter);}@Overridepublic void onListItemClick(ListView l, View v, int position, long id) {super.onListItemClick(l, v, position, id);String str = adapter.getItem(position);transaction = manager.beginTransaction();RightFragment rFragment = new RightFragment();Bundle bundle = new Bundle();bundle.putString("id", str);rFragment.setArguments(bundle);transaction.replace(R.id.right, rFragment, "detail");transaction.commit();Toast.makeText(getActivity(), str, Toast.LENGTH_SHORT).show();}
}

MainActivity

package com.example.test1;import android.app.Activity;
import android.app.FragmentManager;
import android.app.FragmentTransaction;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;public class MainActivity extends Activity {private Button button;private FragmentManager manager;private FragmentTransaction transaction;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);manager = getFragmentManager();button = (Button) findViewById(R.id.button);button.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {transaction = manager.beginTransaction();CenterListFragment centerListFragment = new CenterListFragment();transaction.add(R.id.center, centerListFragment, "center");transaction.commit();}});}}

RightFragment

import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;public class RightFragment extends Fragment {private TextView textView;private View view;@Overridepublic View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {view = inflater.inflate(R.layout.detail, null);textView = (TextView) view.findViewById(R.id.textView);Bundle bundle = getArguments();String str = bundle.getString("id");textView.setText(str);return view;}}
