ListView隔行变色也许我们工作中或用到，有的客户会要求你变换listView的颜色，这样看起来比较好看所以我就自己写了 关于隔行变色的代码。

不多说直接上代码：

这是我自己写的小项目：

要想达到效果，就在适配器中直接设置：

public class ListInfoAdapter extends BaseAdapter {
        private List<ListInfoBean> list;
        private Context context;
    
        public ListInfoAdapter(List<ListInfoBean> list, Context context) {
            this.list = list;
            this.context = context;
        }
    
        private int index = 0;
        private Map<Integer, Boolean> isSelected;
        private int clickPosition = -1;
        private int[] colors=new int[]{
      0x30FF0000,0x300000FF};
    
        @Override
        public int getCount() {
            return list.size();
        }
    
        @Override
        public Object getItem(int position) {
            return null;
        }
    
        @Override
        public long getItemId(int position) {
            return 0;
        }
    
        @Override
        public View getView(final int position, View convertView, ViewGroup parent) {
            final ViewHolder holder;
            if (convertView == null){
                convertView = LayoutInflater.from(context).inflate(R.layout.order_adapter_item,parent,false);
                holder = new ViewHolder(convertView);
                convertView.setTag(holder);
            }else {
                holder = (ViewHolder) convertView.getTag();
            }
            holder.adapter_JD.setText(list.get(position).getName());
            holder.cwNO.setText(list.get(position).getId());
    
            //设置隔行变色
            int colorPos=position%colors.length;
            //颜色设置
            if(colorPos==1) convertView.setBackgroundColor(Color.argb(250, 255, 255, 255));
            else
                //颜色设置
                convertView.setBackgroundColor(Color.argb(255, 224, 243, 250));
    
            return convertView;
        }
        class  ViewHolder{
            TextView adapter_JD,cwNO;
            public ViewHolder(View convertView) {
                adapter_JD = (TextView) convertView.findViewById(R.id.adapter_JD);
                cwNO = (TextView) convertView.findViewById(R.id.cwNO);
    
    
            }

通过适配器我们就可以把它展示到LIstView中 就实现了简单的隔行变色的效果了
