code:

public class CustomAdapter extends ArrayAdapter<String> { 

     private final Activity context; 
     private final String[] countryNames; 
     private final Integer[] imgid; 

     public CustomAdapter(Activity context, Integer flags[],String countryNames[]) { 
      super(context, R.layout.spinner_layout, countryNames); 
      // TODO Auto-generated constructor stub 

      this.context=context; 
      this.countryNames =countryNames; 
      this.imgid=flags; 
     } 

     public View getView(int position,View view,ViewGroup parent) { 
      LayoutInflater inflater=context.getLayoutInflater(); 
      View rowView=inflater.inflate(R.layout.spinner_layout, null,true); 

      TextView txtTitle = (TextView) rowView.findViewById(R.id.textView2); 
      ImageView imageView = (ImageView) rowView.findViewById(R.id.imageView); 

      txtTitle.setText(countryNames[position]); 
      imageView.setImageResource(imgid[position]); 
      return rowView; 

     } 
     @Override 
     public View getDropDownView(int position, View convertView,ViewGroup parent) { 
      return getView(position, convertView, parent); 
     } 

     @Override 
     public String getItem(int position) { 
      return String.valueOf(countryNames.toString()); 
     } 
} 

appel à l'aide:

CustomAdapter customAdapter=new CustomAdapter(MainActivity.this,flags,countryNames); 

Pour une utilisation de mise en page:

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="horizontal"> 

    <ImageView 
     android:id="@+id/imageView" 
     android:layout_width="50dp" 
     android:layout_height="50dp" 
     android:padding="10dp" 
     app:srcCompat="@mipmap/ic_launcher" /> 

    <TextView 
     android:id="@+id/textView2" 
     android:layout_width="wrap_content" 
     android:layout_height="42dp" 
     android:layout_weight="1" 
     android:gravity="center|left" 
     android:text="FDFDFDFD" 
     android:textSize="15sp" 
     android:textAppearance="@style/TextAppearance.AppCompat.Body1" 
     android:textColor="#000000" /> 

</LinearLayout>
