I did search the forum but due to the low number of preferencescreen
example I couldn't find anything directly concerning both
preferenceactivity AND orientation. :-) I did state in my post I had
been reading the tuts on androidguys, unfortunately there is not a
'merged' example of both.
My stripped down version exhibits the same issue:
test.java:
public class test extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
@Override
public boolean onCreateOptionsMenu(Menu menu)
{
super.onCreateOptionsMenu(menu);
MenuItem mi;
mi = menu.add(0,0,0,"Settings");
mi.setIcon(android.R.drawable.ic_menu_preferences);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item){
switch (item.getItemId()) {
case 0:
startActivityForResult(new
Intent(test.this,ShowSettings.class),
30);
return true;
}
return super.onOptionsItemSelected(item);
}
}
ShowSettings.java:
public class ShowSettings extends PreferenceActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.layout.settings);
}
}
settings.xml:
<PreferenceScreen
xmlns:android="http://schemas.android.com/apk/res/android";>
<PreferenceCategory
android:title="Other Preference">
<PreferenceScreen
android:title="Other Preference"
android:summary="Other Preference">
<PreferenceCategory
android:title="Other Preference">
</PreferenceCategory>
</PreferenceScreen>
</PreferenceCategory>
<PreferenceCategory
android:title="Other Preference">
</PreferenceCategory>
</PreferenceScreen>
If I click to the second preferences screen and change orientation I
get:

What I'm asking is: how can I find out what I need to get a handle or
whatever on to correctly control whatever object/widget that is being
used underneath when the activity is recreated?
When displaying the root preferences, this doesn't happen?
