First of all, I know that this was asked several time, but on newer android versions it looks like that the suggested solutions doesn't work. I need that my spinner call OnItemSelected even when the user select the same item twice. I've found this class that should do the trick:
public class NDSpinner extends Spinner {
private int lastSelected = 0;
private static Method s_pSelectionChangedMethod = null;
static {
try {
Class noparams[] = {};
Class targetClass = AdapterView.class;
s_pSelectionChangedMethod = targetClass.getDeclaredMethod("selectionChanged", noparams);
if (s_pSelectionChangedMethod != null) {
s_pSelectionChangedMethod.setAccessible(true);
}
} catch( Exception e ) {
Log.e("Custom spinner, reflection bug:", e.getMessage());
throw new RuntimeException(e);
}
}
public NDSpinner(Context context) {
super(context);
}
public NDSpinner(Context context, AttributeSet attrs) {
super(context, attrs);
}
public NDSpinner(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
@Override
protected void onLayout(boolean changed, int l, int t, int r, int b) {
if(this.lastSelected == this.getSelectedItemPosition())
testReflectionForSelectionChanged();
if(!changed)
lastSelected = this.getSelectedItemPosition();
super.onLayout(changed, l, t, r, b);
}
public void testReflectionForSelectionChanged() {
try {
Class noparams[] = {};
s_pSelectionChangedMethod.invoke(this, noparams);
} catch (Exception e) {
Log.e("Custom spinner, reflection bug: ", e.getMessage());
e.printStackTrace();
}
}
@Override
public void onClick(DialogInterface dialog, int which) {
super.onClick(dialog, which);
}
}
This infact works, but it has a bug: it call twice the item the first time :( Can anybody tell me how can I solve this ?
Thanks mates.
I've solved using this class:
public class NDSpinner extends Spinner {
public NDSpinner(Context context)
{ super(context); }
public NDSpinner(Context context, AttributeSet attrs)
{ super(context, attrs); }
public NDSpinner(Context context, AttributeSet attrs, int defStyle)
{ super(context, attrs, defStyle); }
@Override public void
setSelection(int position, boolean animate)
{
boolean sameSelected = position == getSelectedItemPosition();
super.setSelection(position, animate);
if (sameSelected) {
// Spinner does not call the OnItemSelectedListener if the same item is selected, so do it manually now
getOnItemSelectedListener().onItemSelected(this, getSelectedView(), position, getSelectedItemId());
}
}
@Override public void
setSelection(int position)
{
boolean sameSelected = position == getSelectedItemPosition();
super.setSelection(position);
if (sameSelected) {
// Spinner does not call the OnItemSelectedListener if the same item is selected, so do it manually now
getOnItemSelectedListener().onItemSelected(this, getSelectedView(), position, getSelectedItemId());
}
}
}
Thanks anyway :)
