java - 如何根据值在android中选择json对象

Question

我有以下代码。

{
    "id": 1,
    "name": "A green door",
    "price": 12.50,
    "tags": ["home", "green"]
}
{
    "id": 2,
    "name": "A blue door",
    "price": 10.50,
    "tags": ["home", "blue"]
}

我希望能够只选择具有特定“id”的对象。

 JSONObject json = new JSONObject(result);
    String name = json.opString("name");
    String price = json.optString("price");
    String tags = json.optString("tags");

假设您的 JSON 数据更符合

{
    "objects": [
        {
            "id": 1,
            "name": "A green door",
            "price": 12.5,
            "tags": [
                "home",
                "green"
            ]
        },
        {
            "id": 2,
            "name": "A blue door",
            "price": 10.5,
            "tags": [
                "home",
                "blue"
            ]
        }
    ]
}

可以使用jsonPath来获取，比如只有id == 2

$.objects[?(@.id=='2')]
