As you said that you have use Custom adapter for listview then what you need to do is below.
in getViewmethod of your adapter you need to set background color of your list row xml's parent view.
正如您所说，您已将自定义适配器用于列表视图，那么您需要做的如下。在getView您的适配器方法中，您需要设置列表行 xml 父视图的背景颜色。

in getView(...) method
在 getView(...) method
if (position == 0) {
view.setBackgroundResource(R.drawable.bg_list_even);
} else if (position == 1) {
view.setBackgroundResource(R.drawable.bg_list_odd);
} else...
Update::
更新：：
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
View view = convertView;
ViewHolder holder;
if (view == null) {
LayoutInflater inflater = (LayoutInflater) activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.row, null);
holder = new ViewHolder();
view.setTag(holder);
} else {
holder = (ViewHolder) view.getTag();
}
holder.title = (TextView) view.findViewById(R.id.txttitle);
holder.description = (TextView) view.findViewById(R.id.txtdesc);
holder.title.setText("Title" + position);
holder.description.setText("Desc" + position);
//here set your color as per position
if (position == 0) {
view.setBackgroundResource(R.drawable.bg_list_even);
} else if (position == 1) {
view.setBackgroundResource(R.drawable.bg_list_odd);
}

Make an array as given below as no of list item i suppose u have five items
制作一个如下所示的数组作为列表项的编号，我想你有五个项目
int[] color_arr={Color.BLUE,Color.CYAN,Color.DKGRAY,Color.GREEN,Color.RED};
and after do in ur getView method of custome adapter as below
然后在你的客户适配器的 getView 方法中做如下
public View getView(int position, View convertView, ViewGroup parent)
{
LayoutInflater inflater = getLayoutInflater();
View row=convertView;
row = inflater.inflate(R.layout.listview_custome, parent, false);
row.setBackgroundColor(color_arr[position]);// this set background color
TextView textview = (TextView) row.findViewById(R.id.tv_list);
ImageView imageview = (ImageView) row.findViewById(R.id.iv_list);
textview.setText(data_text[position]);
imageview.setImageResource(data_image[position]);
return (row);
}

public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = getLayoutInflater();
View rowView = convertView;
rowView = inflater.inflate(R.layout.listview_custome, parent, false);
rowView.setBackgroundColor(color_arr[position]);// this set background color
TextView textview = (TextView) rowView.findViewById(R.id.tv_list);
ImageView imageview = (ImageView) rowView.findViewById(R.id.iv_list);
textview.setText(data_text[position]);
imageview.setImageResource(data_image[position]);
if (position == 0) {
rowView.setBackgroundColor(Color.BLUE);
}
else if (position % 2 == 1) {
rowView.setBackgroundColor(Color.RED);
}
else if (position % 2 == 0) {
rowView.setBackgroundColor(Color.BLUE);
}
return (rowView);
}
