我正在使用ARexampleLocationBased教程，POIS ar正确显示，但未显示annottations，程序工作正常，但POI上的billoboards图像不可见
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();
}
}
这是主要的活动代码
