如何使用Volley库解析嵌套的JSON数组? 我的JSON数据结构屏幕截图。 https://prnt.sc/pbaea5
我需要分析分数值。
JSONArray jsonArray = response.getJSONArray("matches");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonObjectMatchs = jsonArray.getJSONObject(i);
// bat_team node is JSON Object
JSONObject bat_teamData = jsonObjectMatchs.getJSONObject("bat_team");
JSONArray jsonArrayInnings = bat_teamData.getJSONArray("innings");
JSONObject jsonObjectInnings = jsonArrayInnings.getJSONObject(i);
String bat_team_score = jsonObjectInnings.getString("score");
}
答案 0 :(得分:0)
您需要进一步迭代
const colors = {
1: "blue",
2: "red",
3: "green"
}
const shirts = [
{id: 1, color: 2},
{id: 2, color: 3},
{id: 3, color: 2},
{id: 4, color: 1},
{id: 5, color: 3}
];
shirts.forEach( shirt => shirt.colorName = colors[shirt.color] )
console.log(shirts)
使用另一个循环,但是在您的代码中,您正在使用父循环的const colors = [
{id: 1, name: "blue"},
{id: 2, name: "red"},
{id: 3, name: "green"}
];
const shirts = [
{id: 1, color: 2},
{id: 2, color: 3},
{id: 3, color: 2},
{id: 4, color: 1},
{id: 5, color: 3}
];
const colorCodes = colors.reduce((o, c) => { o[c.id] = c.name; return o }, {})
shirts.forEach( shirt => shirt.colorName = colorCodes[shirt.color] )
console.log(shirts)
。
它将无法正常工作。
