Android Preferences how to go
In one of my activity's onCreate I am using the following to get the list view. The xml layout being applied i开发者_JS百科s from xml file "country_row". Now I want to use shared preferences to change some of the layout of my listview for eg font color, background color which should be preserved. As I know I can achieve this using the shared preferences. But assuming that I know the way to define it in xml file, in this section how can I apply some of the changes say different font color or background color using the same "country_row" xml file. Or do I have to completely define new xml file? What is the way I am confused.
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this);
int sort = prefs.getInt("sort_pref", -1); // -1 will be the result if no preference was set before
if(sort == 1)
sortOrder = "year";//sort on year
else if (sort == 2)
sortOrder = "country";//sort on country
ContentResolver contentResolver = getContentResolver();
Cursor c = contentResolver.query(CONTENT_URI, null, null, null, sortOrder);
String[] from = new String[] { "year", "country" };
int[] to = new int[] { R.id.year, R.id.country };
SimpleCursorAdapter sca = new SimpleCursorAdapter(this, R.layout.country_row, c, from, to);
setListAdapter(sca);
}
This would be quick and dirty:
new SimpleCursorAdapter(this, R.layout.country_row, c, from, to) {
@Override
public void getView(int position, View convertView, ViewGourp parent) {
convertView = super.getView(position, convertView, parent);
View viewToModify = convertView.findViewByid(/* ID of view to modify */);
// apply your changes here
}
}
The clean solution is to create your own adapter and do it there.
