android - 在android中的JSON数组中解析double[]

Question

我是 android 的新手，我以前使用的是从服务器获取 JSON 数组并解析 JSON 对象，如下所示，

JSONObject objResponse = new JSONObject(retResult);
String objString = objResponse.toString();
String strResponse = null;
if ((objString.contains(getString(R.string.response)))
            || objString.contains((String) getString(R.string.response)
                    .toLowerCase())
            || (objString.contains((String) getString(R.string.response)
                    .toUpperCase()))) {
strResponse = objResponse.getString(getString(R.string.response));
} else {
    strResponse = "";
}

帮我解析一下从服务器返回的JSON,,,

Answer 1

属性 iapStandardHeight 看起来是一个锯齿状的数组。这看起来是您收到的 json 中最复杂的部分。下面是用于从您发布的 json 创建锯齿状双数组的代码。如果您需要更多帮助，只需添加评论即可。

JSONObject jsonResponse = new JSONObject(response);

JSONArray outerArray = jsonResponse.getJSONArray("iapStandardHeight");
double[][] result = new double[outerArray.length()][];

for(int i = 0; i < outerArray.length(); i++){

    JSONArray innerArray = outerArray.getJSONArray(i);
    double[] innerResult = new double[innerArray.length()];

    for(int j = 0; j < innerArray.length(); j++){               
        innerResult[j] = innerArray.getDouble(j);               
    }

    result[i] = innerResult;
}
