ListFragment dans Android Studio

Concernant la dernière question:

Aussi, comment puis-je définir une liste à l'intérieur d'un fragment sans l'aide de ListFragment?

J'ai un code qui pourrait vous aider.

Ici est la MainActivity.java qui comprend un Fragment:

    public class MainActivity extends ActionBarActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction()
.add(R.id.container, new MusicFragment())
.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.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();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
Intent i = new Intent(this, SettingsActivity.class);
startActivity(i);
return true;
}
return super.onOptionsItemSelected(item);
}
/**
* A placeholder fragment containing a simple view.
*/
public static class MusicFragment extends Fragment {
ListView list;
String[] text = { "House of Whispers","Hot Lunch", "Number of the Beast", "Killers"};
Integer[] imageId = { R.drawable.hotlunch1, R.drawable.hotlunch2,
R.drawable.ironmaiden1, R.drawable.ironmaiden2 };
public MusicFragment() {
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_main, container, false);
list = (ListView) rootView.findViewById(R.id.ListView);
CustomAdapter adapter = new CustomAdapter(getActivity() , text, imageId );
list.setAdapter(adapter);
Log.d("CustomAdapter", "MusicFragment onCreateView successful");
return rootView;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
}
}

fragment_main.xml:

<RelativeLayout 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=".MainActivity$PlaceholderFragment">
<ListView
android:id="@+id/ListView"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
</ListView>
</RelativeLayout>

Edit: Comme l'a demandé, voici le CustomAdapter:

public class CustomAdapter extends ArrayAdapter<String> {
private final Activity _context;
private final String[] _text;
private final Integer[] _imageId;
public CustomAdapter(Activity context, String[] text, Integer[] imageId) {
super(context, R.layout.list_item, text);
this._context = context;
this._text = text;
this._imageId = imageId;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = _context.getLayoutInflater();
View rowView = inflater.inflate(R.layout.list_item, null, true);
TextView txtTitle = (TextView) rowView.findViewById(R.id.text);
ImageView imageView = (ImageView) rowView.findViewById(R.id.icon);
txtTitle.setText(_text[position]);
imageView.setImageResource(_imageId[position]);
return rowView;
}
}
