XML : Fragment with a ListView should be replaced with another Fragment with another ListView

I created a new Android project with a Blank Activity (MainActivity.java and fragment_main.xml). I add a Fragment (Liste1.java, fragment_list1.xml and list_item_list1.xml).

If an item is clicked the ListView should replace with another fragment and in this fragment should be a ListView too.

How can I do this?

MainActivity.java:

  public class MainActivity extends AppCompatActivity {    @Override  protected void onCreate(Bundle savedInstanceState) {      super.onCreate(savedInstanceState);      setContentView(R.layout.activity_main);  }    @Override  public boolean onCreateOptionsMenu(Menu menu) {      // Inflate the menu; this adds items to the action bar if it is present.      getMenuInflater().inflate(R.menu.menu_main, menu);      return true;  }    @Override  public boolean onOptionsItemSelected(MenuItem item) {      // Handle action bar item clicks here. The action bar will      // automatically handle clicks on the Home/Up button, so long      // as you specify a parent activity in AndroidManifest.xml.      int id = item.getItemId();        if (id == R.id.action_settings) {            return true;      }        return super.onOptionsItemSelected(item);  }    }    

activity_main.xml:

  <?xml version="1.0" encoding="utf-8"?>    <fragment  xmlns:android="http://schemas.android.com/apk/res/android"  xmlns:tools="http://schemas.android.com/tools"  android:id="@+id/fragment"  android:name="de.programmierenlernenhq.ersteapp.Liste1"  tools:layout="@layout/fragment_liste1"  android:layout_width="match_parent"  android:layout_height="match_parent" />    

Liste1.java:

  public class Liste1 extends Fragment {    public Liste1() { }    @Override  public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {        String [] aktienlisteArray = {              "item 1",  "item 2",  "item 3",  "item 4",  "item 5",                "item 6",  "item 7",  "item 8",  "item 9"      };        List<String> aktienListe = new ArrayList<>(Arrays.asList(aktienlisteArray));        ArrayAdapter <String> aktienlisteAdapter =              new ArrayAdapter<>(                      getActivity(), // Die aktuelle Umgebung (diese Activity)                      R.layout.list_item_liste1, // ID der XML-Layout Datei                      R.id.list_item_aktienliste_textview, // ID des TextViews                      aktienListe); // Beispieldaten in einer ArrayList        View rootView = inflater.inflate(R.layout.fragment_liste1, container, false);        ListView aktienlisteListView = (ListView) rootView.findViewById(R.id.listview_aktienliste);      aktienlisteListView.setAdapter(aktienlisteAdapter);        aktienlisteListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {          @Override          public void onItemClick(AdapterView<?> adapterView, View view, int position, long id) {              // Handle items here              switch (position) {                  case 0: {                        break;                  }              }          }      });        return rootView;  }  }    

fragment_liste1.xml:

  <?xml version="1.0" encoding="utf-8"?>    <FrameLayout  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:paddingLeft="@dimen/activity_horizontal_margin"  android:paddingRight="@dimen/activity_horizontal_margin"  android:paddingTop="@dimen/activity_vertical_margin"  android:paddingBottom="@dimen/activity_vertical_margin"  tools:context=".MainActivityFragment">    <ListView      android:id="@+id/listview_aktienliste"      android:layout_width="match_parent"      android:layout_height="match_parent" />    </FrameLayout>    

list_item_liste1.xml:

  <?xml version="1.0" encoding="utf-8"?>    <TextView  xmlns:android="http://schemas.android.com/apk/res/android"  android:layout_width="match_parent"  android:layout_height="wrap_content"  android:minHeight="?android:attr/listPreferredItemHeight"  android:gravity="center_vertical"  android:id="@+id/list_item_aktienliste_textview" >    </TextView>    

Question 2: Below should be R.string.item1..., but it does not work?!

  String [] aktienlisteArray = {              "item 1",  "item 2",  "item 3",  "item 4",  "item 5",                "item 6",  "item 7",  "item 8",  "item 9" };
