问题似乎是addHole不能防止孔的零长度数组。 因此，您应该检查以确保没有传递零长度数组，因为您正在传递零长度数组。 将防护装置放入并记录捕获的异常会发现您的解析因漏洞而出错。
具体说来
holesArray.add(new LatLng(holes.getJSONArray(j).getDouble(1), holes.getJSONArray(j).getDouble(0)));
正在投掷——
org.json.JSONException: Value [-80.6696999375,35.0941296997] at 1 of type org.json.JSONArray cannot be converted to double
因此，您正在尝试将数组解析为double。 我认为你的问题是这句话——
JSONArray holes = coordinates.getJSONArray(i);
应该是别的东西。 我之前的建议让它工作，但我认为它在语义上不正确，因为它重复了与上面相同的数组。 从你的JSON不清楚洞应该在哪里，但它是你应该开始寻找的地方。 也许像这样，
if (coordinates.getJSONArray(i).length() > 1) {
JSONArray holes = coordinates.getJSONArray(i).getJSONArray(1);
if (holes.length() > 0) {
// new for loop to make holes
for (int j = 1; j < holes.length(); j++) {
holesArray.add(new LatLng(holes.getJSONArray(j).getDouble(1), holes.getJSONArray(j).getDouble(0)));
}
}
}
