和listview同一layout的按钮被复制

这是显示的代码
public void Infoshow()
{
setContentView(R.layout.companyinfo);

    //Button m_back =(Button)findViewById(R.id.button1);

  // GridView gv=(GridView)findViewById(R.id.se1);
    ListView gv=(ListView)findViewById(R.id.listView1);

    //List<HashMap<String, String>> list = new ArrayList<HashMap<String, String>>();

   // list=new DB().CompanyInfo(myOrderCode);
    //list=new DB().CompanyInfo(searchwhere);

    SimpleAdapter adapter = new SimpleAdapter(
         MainActivity.this, 
            //this,
            list, 
            R.layout.companyinfo, 
            new String[] { "OrderCode", "ProductName_CN", "ProductName_JP" ,"OrderNum"}, 
            new int[] { R.id.txt_OrderCode, R.id.txt_ProductName_CN, R.id.txt_ProductName_JP , R.id.txt_OrderNum});

    gv.setAdapter(adapter);

这是页面布局

这是效果图

你这分activity的layout和listview的item了吗？怎么看着像是没有区分layout和item这两种布局方式

 setContentView(R.layout.companyinfo);//这里是companyinfo布局
 SimpleAdapter adapter = new SimpleAdapter(
         MainActivity.this, 
            //this,
            list, 
            R.layout.companyinfo, //item也是companyinfo布局

应该如何去修改
