How to achieve nested spinner? [closed]

Answer 1

Look, I am not sure if you are looking for something like that. I have 2 spinner, when the user select a item from brandspinner, the modelspinner is setted with all the products of this brand.

private Spinner brandSpinner;
private Spinner modelSpinner;

brandSpinner = (Spinner)root.findViewById(R.id.brand_spinner);      
modelSpinner = (Spinner)root.findViewById(R.id.model_spinner);


brandsAdapter = new ArrayAdapter<BrandItem>(mContext, android.R.layout.simple_spinner_dropdown_item, ArrayListWithBrands);

//I am not sure if it is needed:                                                
brandsAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

brandSpinner.setAdapter(brandsAdapter);

brandSpinner.setOnItemSelectedListener(new OnItemSelectedListener() {
    @Override
    public void onItemSelected(AdapterView<?> a, View v, int pos, long id) {

        //Harcoding Brands:
        BrandItem brand = brandsArrHarcode.get(pos);    

        final ArrayList<String> modelsArr = brand.getModels();

        modelsAdapter = new CustomArrayAdapter(mContext, android.R.layout.simple_spinner_dropdown_item, modelsArr);

        modelsAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

        modelSpinner.setAdapter(modelsAdapter);

        modelSpinner.setSelection(modelsAdapter.getPosition(camera.getModel()));
    }

    @Override
    public void onNothingSelected(AdapterView<?> a) {} 
}

);

Hope to be helpful.
