Integer Array list in Array Adapter in android

Question

I am working on google maps api, in which on map screen i want to give an option for a user to select map type through spinner. The return type of map option is integer so i am giving that value to spinner for selection through Integer Array. My code snippet is given below:

private GoogleMap mMap;

    int normMap = mMap.MAP_TYPE_NORMAL;
    int satelliteMap =mMap.MAP_TYPE_SATELLITE;
    int terrainMap =mMap.MAP_TYPE_TERRAIN; 
@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.my_location_demo);
        spinnerOsversions = (Spinner) findViewById(R.id.spinner1);

        ArrayAdapter<Integer> adapter_state = new ArrayAdapter<Integer>(this,
            android.R.layout.simple_spinner_item, mapOptions);
    //Here it shows an error that Integer should not be passed to it,  want to send my mapType int array list to it   

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

          spinnerOsversions.setAdapter(adapter_state);
          spinnerOsversions.setOnItemSelectedListener(this);

    }

and whats the problem? Please be specific and post stack trace.. — Opiatefuchs, Nov 11 '14 at 13:43
You have to create a custom array adapter for using array list inside the adapter. You want code for that? — Mohammed Ali, Nov 11 '14 at 13:53
@Opiatefuchs this is what i am getting when i put Integer in ArrayAdapter: The constructor ArrayAdapter(MyLocationActivity, int, int[]) is undefined — Usman Khan, Nov 11 '14 at 14:07
@MohammedAli can you please send me that custom code according to my described cpndition? — Usman Khan, Nov 11 '14 at 14:08
@muhammad usman khan have you created a custom array adapter? If you want to use arraylist inside adapter it is better to use custom BaseAdapter. — Mohammed Ali, Nov 11 '14 at 14:15
@MohammedAli i haven't create a custom BaseAdapter. Can you please describe it with little bit custom code, so i can implement or amend it according to my condition. — Usman Khan, Nov 11 '14 at 14:24
what's the class name for your mapOptions variable. I am guessing mapType..tell me? — Mohammed Ali, Nov 11 '14 at 14:32
@MohammedAli i am just taking GoogleMap object and through this i am implementing mMap for my Map Options. It is a built-in method from Google API. — Usman Khan, Nov 11 '14 at 14:49

Assuming Class name for the variable mapOptions is YourClass, modify your code to:

ArrayAdapter<YourClass> adapter_state = new ArrayAdapter<YourClass>(this,
        android.R.layout.simple_spinner_item, mapOptions);

In the android docs:
public ArrayAdapter (Context context, int resource, T[] objects)
Constructor Parameters
context - The current context.
resource - The resource ID for a layout file containing a TextView to use when instantiating views.
objects - The objects to represent in the ListView.

i am just taking GoogleMap object and through this i am implementing mMap for my Map Options. It is a built-in method from Google API. I am just passing data comming from mMap to my defined Integers and from there i am going to make an integer array list to display in spinner. – Usman Khan Nov 11 '14 at 14:52
private GoogleMap mMap; int normMap = mMap.MAP_TYPE_NORMAL; int satelliteMap =mMap.MAP_TYPE_SATELLITE; int terrainMap =mMap.MAP_TYPE_TERRAIN; private int[] mapOptions = { normMap,satelliteMap,terrainMap }; – Usman Khan Nov 11 '14 at 14:54
