android - How to correctly overwrite methods of SpinnerAdapter -

Text after "

Im using a SpinnerAdapter to display a spinner. For this, I defined a class implementing spinner adapter. Unfortunately I do not know how to override some methods of SpinnerAdapter:

  @Override Public View getDropDownView (integer status, see ARG1, ViewGroup ARG2) {} @Override public integer getItemViewType (integer arg0) {} @Override public boolean hasStableIds () {} @Override public void registerDataSetObserver (DataSetObserver arg0) {} @Override public void unregisterDataSetObserver (DataSetObserver observer) {}  

Does anyone know What is I to code in each of these methods?

After text "itemprop =" text ">

Thanks for the answer, but still I want to share with you the solution Used after:

Instead of simply implementing the SpinnerAdapter in my adapter, I apply the SpanAdapter extension and apply the SpinnerAdapter:

  the Private Class ListAdapter extends the BaseAdapter SpinnerAdapter {@ Override Public Inaccount () {Return to allLists.size}; } @OverWide Public Object Mengate (Return of the status) {All Lists.Jet (Status); } @ Override Public Long ITMID (Status of Intake) {Return Status; } @ Override public view getView (int position, view view, viewgroup parent) {TextView text = new text view (Lex); Text.setText (allLists.get (status) .getName ()); Return text; }}  

So to override this in all this weird methods such as isEmpty (), registerDataObserver (), etc.

And if necessry as a still are not required to override getDropDownView (...)

Use the addition of this solution, which is a adapter.notifyDatasetChanged () is not easy, so the adapter can say applies only SpinnerAdapter and BaseAdapter does not extend.
