I am developing a PreferenceActivity with
custom Preference views. My problem is that I created a view with a
ListView and it only shows the first element. I post my code and an image:

android:dialogTitle="@string/settings_playersname"

</PreferenceCategory>
<PreferenceCategory

<PreferenceCategory

<com.battleship.preferences.ListPreferences android:key="theme" />
</PreferenceCategory>
<PreferenceCategory
android:key="fontsTitle"
android:title="@string/settings_group_font_size" >
<com.battleship.preferences.ListPreferences android:key="font" />
</PreferenceCategory>
</PreferenceScreen>
The
Custom ListPreference:

import android.widget.Toast;
public class ListPreferences extends Preference implements
OnCheckedChangeListener {
public ListPreferences(Context context) {
super(context);
}
public ListPreferences(Context context, AttributeSet attrs) {
super(context, attrs);
}
public ListPreferences(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
@Override
protected void onClick() {
super.onClick();
Toast t = Toast.makeText(getContext(), "HOLA!", 3);
t.show();
}
@Override
protected View onCreateView(ViewGroup parent) {
String[] contentString = new String[3];
if (getKey().equals("theme")) {
contentString = new String[] {
(getContext().getString(R.string.settings_theme_default)),
(getContext().getString(R.string.settings_theme_black)),
(getContext().getString(R.string.settings_theme_white)) };
} else {
contentString = new String[] {
(getContext().getString(R.string.settings_font_big)),
(getContext().getString(R.string.settings_font_medium)),
(getContext().getString(R.string.settings_font_little)) };
}
ListView listView = new ListView(getContext());
ArrayAdapter<String> array = new ArrayAdapter<String>(getContext(),
android.R.layout.simple_list_item_single_choice,
android.R.id.text1, contentString);
listView.setAdapter(array);
listView.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
return listView;
}
private void updatePreference(int intRadio) {
SharedPreferences.Editor editor = getEditor();
editor.putInt(getKey(), intRadio);
editor.commit();
}
}
