我正在开发应用的Android版本，我正在尝试复制此图片中显示的设计。 http://s1298.photobucket.com/user/Mitch_Thornton/media/Screenshot2013-06-03at50428PM_zps3d9b6acc.png.html?sort=3&o=0
我存储的数据来自网站。到目前为止，我已成功完成，因此自动完成功能可以正确搜索数据。 我的问题是格式化。我希望能够控制和风格化文本的某些部分。特别是百分比。如果百分比高于75％，则应为绿色，如果低于该值，则应为红色或黄色。
问题是，我正在递一根长串，所以我无法单独设计某些部分。
我通过添加空格和一条线来获得一个穷人的造型版本，但没有什么特别的.... 这是我到目前为止所拥有的 http://s1298.photobucket.com/user/Mitch_Thornton/media/Screenshot2013-06-03at51100PM_zps6859e634.png.html?sort=3&o=1
我是Android的新手，所以我到目前为止所获得的内容主要来自教程和一些自学。我非常感谢您的帮助

答案 0 :(得分：1)
答案是自定义列表视图而不是设置长单字符串，而是使用具有不同属性的模型，在这里查看一个很好的示例how to customize listview row android
查看模板膨胀的adpapter，它代表每一行
public View getView(int position, View convertView, ViewGroup parent){
String myText = getItem(position);
if(convertView == null){ // If the View is not cached
// Inflates the Common View from XML file
convertView = this.inflater.inflate(R.id.my_row_layout, null);
}
// Select your color and apply it to your textview
int myColor;
if(myText.substring(0, 1) == "a"){
myColor = Color.BLACK;
}else{
....
}
