I don't see what the problem is....
You have a Spinner and you you have a
Spinner.OnItemSelectedListener....
Now you have this;
private class MyOnItemSelectedListener implements
Spinner.OnItemSelectedListener{
public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
//DO STUFF
}
}
Note: View arg1 ---- this is the View that the user selected!
I.e. ANY class that extends View... MyView mv = (MyView)arg1;
OR: arg0 is the SPINNER within which the item was selected, i.e.
arg0.getSelectedItem()
--- i.e. in the case that you are using a drop down view (label of the
view is item.toString()).
private class MyNuttyMultiIndexedView extends SomeView{
private int extraIndex1;
private int extraIndex2;
private int extraIndex3;
MyNuttyMultiIndexedView(Context c, index1, index2, index3){
super(c);
extraIndex1=index1;
extraIndex2=index2;
extraIndex3=index3;
}
public int getIndex1(){
return extraIndex1;
}
public int getIndex2(){
return extraIndex2;
}
public int getIndex3(){
return extraIndex3;
}
}
public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
//grab your indexes from ((MyNuttyMultiIndexedView)arg1).getIndexN()
}
You could even ignore the parameters to onItemSelected and get it all
manually like this;
onItemSelected(ignoreparameters){
MyNuttyMultiIndexedView m = (MyNuttyMultiIndexedView)
globalspinner.getSelectedItem();
//do something with m.getIndexN();
}
private class MyData{
private String label;
private int index;
public MyData(int index, String label){
this.label=label;
this.index=index;
}
public String toString(){
return label;
}
public int getIndex(){
return index;
}
}
private class MyOnItemSelectedListener implements
Spinner.OnItemSelectedListener{
public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
MyData d = (MyData)arg0.getSelectedItem();
//your customized index is available at d.getIndex()!!!
}
}
If you think that Android is awkward to code for, maybe you should try
blackberry... you pretty much have to fight the API every step along
the way. 'Droid is a breeze.
