Answer 1

楼主这个问题提的太初略了，能不能再详细点，是继承了什么adapter？

Answer 2

我的是创建了一个对象 具体代码是：
BaseAdapter ba_detail=new BaseAdapter()//新建适配器
      {
  
@Override
public int getCount() 
{
return 5;//得到列表的长度
}
@Override
public Object getItem(int arg0){return null;}
@Override
public long getItemId(int arg0){return 0;}
@Override
public View getView(int arg0, View arg1, ViewGroup arg2)//为每一项添加内容
{
LinearLayout ll_detail=new LinearLayout(sprinkler_detail_infomation.this);
ll_detail.setOrientation(LinearLayout.HORIZONTAL); //设置朝向
ll_detail.setPadding(5,5,5,5);
ll_detail.setGravity(Gravity.CENTER);//四周留白

TextView tv1=new TextView(sprinkler_detail_infomation.this);
tv1.setWidth(50);
tv1.setHeight(50);
tv1.setGravity(Gravity.CENTER);
tv1.setText(gNameAndgDetail[arg0*10+(modify_number-1)*50]);
tv1.setTextColor(getResources().getColor(R.color.text_color));
ll_detail.addView(tv1);
TextView tv2=new TextView(sprinkler_detail_infomation.this);
tv2.setWidth(72);
tv2.setHeight(50);
tv2.setGravity(Gravity.CENTER);
tv2.setText(gNameAndgDetail[arg0*10+(modify_number-1)*50+1]);
tv2.setTextColor(getResources().getColor(R.color.text_color));
ll_detail.addView(tv2);

TextView tv3=new TextView(sprinkler_detail_infomation.this);
tv3.setWidth(123);
tv3.setHeight(50);
tv3.setGravity(Gravity.CENTER);

tv3.setTextColor(getResources().getColor(R.color.text_color));
ll_detail.addView(tv3);

TextView tv4=new TextView(sprinkler_detail_infomation.this);
