Android-自定义listView，每行颜色不同 [英] Android - custom listView, each row different colours

问题描述

我已经创建了自定义列表视图，每一行看起来都像我的文件custom_row.xml.有什么办法，如何分别为每一行设置不同的背景颜色(我需要设置它，因为我的行可以具有不同的值).

I have created custom listview, each row looks like my file custom_row.xml. Is there any way, how to set up different background colors for each row separately (I need to set it because of different values my rows can have).

感谢任何想法

推荐答案

由于您在getView方法中执行了自定义listview使custom_row.xml膨胀后，请更改背景返回inflate方法的视图.请参见下面的示例代码片段:

Since your doing custom listview in the getView method after inflating your custom_row.xml change the background of the return view of inflate method. See sample snippet below:

public getView(int position, View convertView, ViewGroup parent) {
       convertView = getLayoutInflater().inflate(R.layout.custom_xml, null);
       do some stuff...

       //let say you have an arraylist of color
       convertView.setBackgroundColor(arraylist.get(position));

       //in case that your color is limited, just re-use your color again
       //and some logic how to re-use the colors.
}
