I have a basket icon with count notification on it in actionbar for showing number of goods in shopping basket. also I have a custom view containing a button for add goods to shopping basket. I want that when I click on button (in custom view) notification count on basket icon increases. I use this function in main activity to update notification count but notification does not update.
public static void updateCountBasket(final int number , int id , View view ,Context context) {
if (view.findViewById(id) == null)
return;
TextView t = (TextView)view.findViewById(id);
String dd = t.getText().toString();
((Activity) context).runOnUiThread(new Runnable() {
@Override
public void run() {
if (number == 0)
t.setVisibility(View.INVISIBLE);
else {
t.setVisibility(View.VISIBLE);
t.setText(Integer.toString(number));
}
}
});
}
but when I use non static of that function in main activity with simple button on click, it works fine. but I can't call non static function in base adapter too :( . I checked line by line of the function in static mode all ids are right and it set text too but nothing change or get error!!. please help me to change textview as notification of basket in menubar from base adapter when button in custom view clicks. thanks I have this base adapter for my custom view list:
public class Goods_ImageAdapter extends BaseAdapter {
private Context context;
private final JSONArray Goods;
private Bagde bagde;
public Goods_ImageAdapter(Context context , JSONArray Goods) {
this.context = context;
this.Goods = Goods;
bagde = Bagde.getInstance();
}
@Override
public int getCount() {
return Goods.length();
}
@Override
public Object getItem(int arg0) {
return null;
}
@Override
public long getItemId(int arg0) {
return 0;
}
public static String doubleToStringNoDecimal(double d) {
DecimalFormat formatter = (DecimalFormat) NumberFormat.getInstance(Locale.US);;
formatter .applyPattern("#,###");
return formatter.format(d);
