In the below example I have created Custom View spinner. Here first I have created a row.xml layout , In row.xml I have added a TextView and Button. Then I have created drop.xml layout in this I have added two TextView with in LinearLayout, Then in next step In activity_main.xml layout I have added a Spinner and TextView. Now see In MainActivity I have created new MyClass and MySpinnerAdapter class and extends ArrayAdapter class and I have used getDropDownView method. You can see below program it will clearly describe you How to make  custom Spinner in android.

Step(1)-Created row.xml layout-

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">
    <TextView
        android:id="@+id/gotext"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:textSize="20sp"
        android:textStyle="bold"/>
    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/button"/>

</LinearLayout>

Step(2)-Created drop.xml layout-
 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:padding="10dp">
    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:textSize="20sp"
        android:textStyle="bold"
        android:id="@+id/gotext"/>
    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:textStyle="italic"
        android:id="@+id/address"/>

</LinearLayout>

Step(3)-Created actvity_main.xml layout-
 

<LinearLayout 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:orientation="vertical"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.example.androidspinnertext.MainActivity" >

    <Spinner
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:id="@+id/spinner"/>
    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:id="@+id/textgo"/>

    </LinearLayout>

Step(4)-MainActivity-
    
   

public class MainActivity extends Activity {
    MyClass[]objGo={
            new MyClass("FindNerd", "http://findnerd.com/account#url=/users/showDetails"),
            new MyClass("Evon-tec", "http://www.evontech.com/"),
            new MyClass("Android developers", "http://developer.android.com/training/index.html"),
            new MyClass("JavaTpoint", "http://www.javatpoint.com//"),
            new MyClass("Google-Play", "https://play.google.com/store")
    };
    Spinner spinner;
    TextView textView;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        textView=(TextView)findViewById(R.id.textgo);
        spinner=(Spinner)findViewById(R.id.spinner);
        MySpinnerAdapter adapter=new MySpinnerAdapter(MainActivity.this,R.layout.row,objGo);
        spinner.setAdapter(adapter);

    }
    AdapterView.OnItemSelectedListener onItemSelectedListenerGo =new AdapterView.OnItemSelectedListener(){


        @Override
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
            MyClass obj =(MyClass)(parent.getItemAtPosition(position));
            textView.setText(String.valueOf(obj.getTarget()));

        }

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

        }

        };
        public class MyClass{
            private String text;
            private String target;

        public MyClass(String text,String target)
        {
            this.text=text;
            this.target=target;
        }
        public void setText(String text){
            this.text =text;
        }
            public String getText(){
                return this.text;
            }
            public void setValue(String target){
                this.target=target;
            }
            public String getTarget(){
                return this.target;
            }

        }

    public class MySpinnerAdapter extends ArrayAdapter<MyClass>{

        private  MyClass[]myobjs;
        public MySpinnerAdapter(Context context,int textViewResourceId,MyClass[]myobjs){
           super(context,textViewResourceId,myobjs);
           this.myobjs=myobjs;

        }
        public int getCount(){
            return myobjs.length;
        }
        public MyClass getItem(int position){
            return myobjs[position];
        }
        public long getItemId(int position){
            return position;
        }

        public View getView(final int position,View convertView,ViewGroup parent){
            LayoutInflater inflater =getLayoutInflater();
            View spView =inflater.inflate(R.layout.row, parent, false);

            TextView sp_GoText = (TextView)spView.findViewById(R.id.gotext);
            sp_GoText.setText(myobjs[position].getText());


            Button button=(Button)spView.findViewById(R.id.button);
            button.setText(myobjs[position].getTarget());

            button.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    Uri uri =Uri.parse(myobjs[position].getTarget());
                    Intent intent = new Intent(Intent.ACTION_VIEW,uri);
                    startActivity(intent);
                }
            });

 return  spView;


    }
        @Override
        public View getDropDownView(int position,View convertView,ViewGroup parent){
            LayoutInflater inflater=getLayoutInflater();

            View dropDownView =inflater.inflate(R.layout.drop, parent, false);
            TextView dd_GoText = (TextView)dropDownView.findViewById(R.id.gotext);
            dd_GoText.setText(myobjs[position].getText());

            TextView address =(TextView)dropDownView.findViewById(R.id.address);
            address.setText(myobjs[position].getTarget());
            return  dropDownView;

        }


    }
    }
