android - ListView 替代颜色

Question

我需要制作一个具有替代颜色的 ListView。

代码:

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

  if(position %2==0)
  {
      view.setBackgroundColor(Color.BLUE);
  }
  return view;
}

但我不知道如何在我的适配器中使用它:

SimpleAdapter adapter = new SimpleAdapter(this, propositions, android.R.layout.simple_list_item_2,
    new String[] {"Date", "Trajet"},
    new int[] { android.R.id.text1, 
    android.R.id.text2});
lvTrajets.setAdapter(adapter);

有人可以帮我解决这个问题吗？

Answer 1

为适配器覆盖 getView

SimpleAdapter adapter = new SimpleAdapter(this, propositions, android.R.layout.simple_list_item_2,
new String[] {"Date", "Trajet"},
new int[] { android.R.id.text1, 
android.R.id.text2})
    {
        @Override
        public View getView (int position, View convertView, ViewGroup parent)
        {
            View v = super.getView(position, convertView, parent);
             if(position %2==0)
             {
                  v.setBackgroundColor(Color.BLUE);
             }
             else
             {
                  v.setBackgroundColor(Color.WHITE);
             }

            return v;
        }


    };
