Мое круговое изображение не работает должным образом

Question

Я следую этому примеру [здесь] [1], чтобы получить форму циркулятора. Я получаю изображения с сервера и устанавливаю его через BaseAdapter, изображение отображается, но не в круговом виде. Итак, кто может сказать, что это ошибка с моим кодом, следующее как я загружать изображения и установить круглую форму

aQuery.id(holder.propic).image(listData.get(position).get(INTEREST_ACCEPT_IMG),true,true,0,R.drawable.ic_launcher); 


Bitmap icon = BitmapFactory.decodeFile(listData.get(position).get(INTEREST_ACCEPT_IMG)); 

holder.propic.setImageBitmap(icon);

} 

и использовать его в containt_activity.xml так:

<com.example.customewidget.CircleImageView 
      android:id="@+id/imgUserImage" 
      android:layout_width="50dp" 
      android:layout_height="50dp" 
      android:src="@drawable/no_image_available" 
      app:border_color="@color/white" 
      app:border_width="1dp" /> 

Добавить в вас активность или класс фрагментировать:

public class ImageActivity extends Activity { 
    private CircleImageView imgUserImage; 

@Override 
    public void onCreate(Bundle savedInstanceState) { 
    setContentView(R.layout.containt_activity); 

    imgUserImage = (CircleImageView) view.findViewById(R.id.imgUserImage); 
    //here set your image view 
}
