react-native之在 native react 中具有交替颜色的 ListView

我有一系列对象，如下例所示；

[{ 
        "id" : 13100, 
        "key" : "Emlak Vergisi", 
        "y" : 135638.98 
    }, { 
        "id" : 13154, 
        "key" : "Çevre Temizlik ", 
        "y" : 956.17 
    }, { 
        "id" : 19998, 
        "key" : "Genel Tahakkuk", 
        "y" : 89030.62 
    }, { 
        "id" : 24998, 
        "key" : "Gecekondu ve So", 
        "y" : 42721.07 
    }, { 
        "id" : 60000, 
        "key" : "Ortak Gelirler", 
        "y" : 827.42 
    } 
] 

请您参考如下方法:

我会说这种方法更干净:

 renderRow(rowData, sectionID, rowID) { 
 
   let style = [ 
         styles.row,  
         {'backgroundColor': colors[rowID % colors.length]} 
       ]; 
 
   return (<View style={style}/>); 
 } 
 
 let colors = ['#123456', '#654321', '#fdecba', '#abcdef']; 
 
 let styles = StyleSheet.create({ 
       row: { 
            // .. rows style 
       } 
 });
