android – 为列表视图中的每个元素设置不同的分隔符颜色

这是一个XML布局示例：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical" >

    <TextView 
        android:id="@+id/text"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" />

    <View 
        android:id="@+id/divider"
    android:layout_width="fill_parent"
    android:layout_height="1dp"
    android:background="#FFFFFFFF" />

</LinearLayout>

这就是你改变适配器颜色的方法：

public class MyAdapter extends BaseAdapter {
    /** List of items to show */
    private ArrayList<String> items = new ArrayList<String>();
    private Context context;
    private int color[];

    public OffersAdapter(Context c,ArrayList<String> items,int color[])
    {
        super();
        this.context = c;
        this.items = items;
        this.color = color;
    }

    public int getCount() {
        return items.size();
    }

    public Object getItem(int position) {
        return null;
    }

    public long getItemId(int position) {
        return 0;
    }

public View getView(final int position,View convertView,ViewGroup parent) {
    final ViewHolder viewHolder;

    if(null == convertView)
    {
        LayoutInflater inflater = LayoutInflater.from(context);
        convertView = inflater.inflate(R.layout.list_item,parent,false);

        viewHolder.text = (TextView) convertView.findViewById(R.id.text);
        viewHolder.divider = (View) convertView.findViewById(R.id.divider);

        convertView.setTag(viewHolder);
    } else {
        //Retrieve the current view
        viewHolder = (ViewHolder) convertView.getTag(); 
    }

    //This is where you chance the divider color based on the item  
    viewHolder.divider.setBackgroundColor(color[position]);

  viewHolder.text.setText(items.get(position));

    return convertView;
}

//Holds the current view
 private static class ViewHolder {
         public TextView text;
         public View divider;
     }   
}

其中int color []是您要使用的颜色列表.
