微调器动态错误

-1

我的Android应用程序出现错误。我有一个类LineaArticulo动态来形成一个带标签的行，编辑文本，按钮和微调，以加强微调我得到一个错误，在这里附加类的构造函数。微调器动态错误

所有数据都是正确的。

这里只是把微调框的情况。

public LineaArticulo(RelativeLayout layoutactual, final String[] Casos, Context context, int Xspinner, int Yspinner){ 

    final Spinner spiner = new Spinner(context); 

    ArrayAdapter<String> adaptador = 
      new ArrayAdapter<String>(context, 
        android.R.layout.simple_spinner_item, Casos); 

    adaptador.setDropDownViewResource(
      android.R.layout.simple_spinner_dropdown_item); 

    spiner.setAdapter(adaptador); 

    RelativeLayout.LayoutParams paramSpiner = new RelativeLayout.LayoutParams(
      ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT); 
    paramSpiner.leftMargin = Xspinner; // Your X coordinate 
    paramSpiner.topMargin = Yspinner; // Your Y coordinate 
    spiner.setLayoutParams(paramSpiner); 

    layoutactual.addView(spiner); 
}

错误：
