调用自定义适配器时应用程序崩溃
Application crashes when custom adapter is called
我已经创建了自定义 Adapter 并且我已经将 Arraylist 传递给它。但是当我调用这个适配器时，我的应用程序崩溃并出现以下错误：

我的自定义适配器代码是：
public class SuerveryAdapter extends BaseAdapter {
private Activity activity;
private ArrayList<serveyData> data;

}
@Override

public class viewHolder{
public TextView tvId;
public TextView tvName;

public Button select;

@Override
public View getView(int position, View convertView, ViewGroup parent) {

//holder.tvDesc=(TextView) v1.findViewById(R.id.textViewDesc);
holder.select=(Button) v1.findViewById(R.id.btnDelete) ;

//Toast.makeText(activity,ser_obj.getId()+ser_obj.getName()+ser_obj.getDesciption(),Toast.LENGTH_SHORT).show();
}
return v1;
}
}
我的调用代码是
listView =(ListView)findViewById(R.id.slistview);
SuerveryAdapter suerveryAdapter= new SuerveryAdapter(SuerveyUserActivity.this,arrayList,getResources());
listView.setAdapter(suerveryAdapter);
请指导如何解决这个问题。
Xml 我的自定义列表的文件 listview 是

您正在将 int 值设置为 TextView。然后 TextView 期望来自您的资源的文本具有该 int 值 (ser_obj.getId())。更改此行：
holder.tvId.setText(ser_obj.getId());
有了这个：
holder.tvId.setText(String.valueOf(ser_obj.getId()));
祝你好运。
检查您的 Textview ID
holder.tvId=(TextView) v1.findViewById(R.id.tvName);
holder.tvName=(TextView) v1.findViewById(R.id.textViewName);
应该是
holder.tvId=(TextView) v1.findViewById(R.id.tvID);
holder.tvName=(TextView) v1.findViewById(R.id.tvName);
