在运行时将数据分配给四维数组

Question

我有一个四维数组，其中有一组静态值。但是我的问题是我想从api中获取一些数据，并且必须在运行时期间将其放入四维数组。我不知道该怎么做。任何微小的想法都会很感激。下面是我的示例，它显示了我的四维数组的静态定义。

static final String listdesc[][][][] =
{
    { // grey
      {  // lightgray
        { "grey", "grey only" },
        { "lightgrey","#D3D3D3" },
        { "dimgrey","#696969" }
      },
      {  // darkgray
        { "grey", "darkgrey" },
        { "sgi grey 92","#EAEAEA" }
      }
    },
    { // blue
      {  // lightblue
        { "blue", "lightblue" },
        { "dodgerblue 2","#1C86EE" }
      },
      {  // darkblue
        { "blue", "darkblue" },
        { "steelblue 2","#5CACEE" },
        { "powderblue","#B0E0E6" }
      }
    },
    { // yellow
      {  // lightyellow
        { "yellow", "lightyellow" },
        { "yellow 1","#FFFF00" },
        { "gold 1","#FFD700" }
      },
      {  // darkyellow
        { "yellow", "darkyellow" },
        { "darkgoldenrod 1","#FFB90F" }
      }
    },
    { // red
      {  // lightred
        { "red", "lightred" },
        { "indianred 1","#FF6A6A" }
      },
      {  // darkred
        { "red", "darkred" },
        { "firebrick 1","#FF3030" },
        { "maroon","#800000" }
      },
    }
};

Answer 1

这叫做primitive obsession code smell。你应该用适当的数据结构和API来替换4d字符串数组来创建它:

ColorsData data = new ColorsData();
ColorSection section = data.addSection("gray");
section.setLightColors(
        "grey only",
        Color.create("lightgray", "#D3D3D3"),
        Color.create("dimgray", "#696969"))
section.setDarkColors(
        "darkgray",
        Color.create("sgi grey 92", "#EAEAEA")
);
section = data.addSection("blue")
...

在AsyncTask/background中获取数据，并在postExecute中分配数据。

listdesc[][][][];
for (int i=0; i<listdesc.length; i++) {
    for (int j=0; j<listdesc[i].length; j++) {
        for (int k=0; k<listdesc[i][j].length; k++) {
            for (int m=0; m<listdesc[i][j][k].length; m++) {
                // populate with values
            }
        }
    }
}
