setChoiceMode in GridView with custom ArrayAdapter does not work

[Alireza Azadi]

I recently want to have my custom ArrayAdapter.
I googled and find some samples, and i did my ArrayAdapter like this.

  public class CarAdapter extends ArrayAdapter<Car> {
    public CarAdapter(Context context, int resource, ArrayList<Car> carArrayList) {
        super(context, resource, carArrayList);
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        Car car = getItem(position);
        if(convertView == null)
        {
            convertView = LayoutInflater.from(getContext()).inflate(R.layout.item_car,parent, false);
        }

        TextView carName =  (TextView)convertView.findViewById(R.id.textView2);
        TextView carSIM = (TextView)convertView.findViewById(R.id.textView);

        carName.setText(car.getName());
        carSIM.setText(car.getSIM());


        return convertView;
    }

}

OK.
(Car is a class with some fields)

And i made a custom layout for this Adapter with two TextView.
Here is the XML Layout for this.

      <?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:orientation="horizontal" android:layout_width="match_parent"
        android:layout_height="match_parent"
        >
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textAppearance="?android:attr/textAppearanceLarge"
            android:text="Small Text"
            android:id="@+id/textView2" />
    
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="New Text"
            android:textAppearance="?android:attr/textAppearanceLarge"
            android:layout_marginLeft="20dp"
            android:id="@+id/textView" />
    </LinearLayout>

OK. I want to display Above Layout as a row to a GridView.
So i made my Main Layout as below :

    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
        android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"
        android:paddingRight="@dimen/activity_horizontal_margin"
        android:paddingTop="@dimen/activity_vertical_margin"
        android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".DisplayActivity">
    
[code=java]        <LinearLayout
            android:orientation="vertical"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_alignParentRight="true"
            android:layout_alignParentEnd="true"
            android:layout_alignParentBottom="true"
            android:layout_alignParentLeft="true"
            android:layout_alignParentStart="true">
            <GridView
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:id="@+id/gridView"
                android:background="#890"
                android:layout_gravity="center_horizontal"
                android:layoutDirection="rtl"/>
        </LinearLayout>
    </RelativeLayout>

I make a simple GridView.

In my MainActivity and onCreate method :

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_display);

        carArrayList = new ArrayList<Car>();
        gridView = (GridView) findViewById(R.id.gridView);
        gridView.setChoiceMode(GridView.CHOICE_MODE_SINGLE);
        carAdapter = new CarAdapter(getApplicationContext(), android.R.layout.select_dialog_singlechoice, carArrayList);
        car = new Car("Dani", "Alvez");
        car2 = new Car("Leo", "Messi");
        carArrayList.add(car);
        carArrayList.add(car2);
        carAdapter.getItemViewType(R.id.gridView);
        gridView.setAdapter(carAdapter);

OK, it display my new Car properly in GridView.
But when i do setChoiceMode in my GridView, it does not act.
Previously i setChoiceMode in simple GridView and it effected.
What should i do?
when i select, it effect, and i cant return the value of selected item in GridView.
But in view setChoiceMode does not work.
