我使用ARexampleLocationBased教程，POI的AR顯示正確，但annottations沒有顯示,,程序工作正確的，但在billoboards圖像下來的POI是不可見的POI的廣告牌不顯示
package pfg.proyecto.com.proyecto;
import android.view.View;
import com.metaio.sdk.ARELActivity;
public class ARELViewActivity extends ARELActivity
{
@Override
protected int getGUILayout()
{
return R.layout.activity_main;
}
public void onButtonClick(View v)
{
finish();
}
}
這是主要的活動代碼
