我有以下的JSON文件。我想知道我应该把JSON文件在我的项目以及如何读取并存储。

  {
aakash：[
    [0.070020,0.400684]
    [0.134198,0.515837]
    [0.393489,0.731809]
    [0.281616,0.739490]

]
anuj：[
    [1287.836667，-22.104523]
    [-22.104523,308.689613]
    [775.712801，-13.047385]
    [-13.047385,200.067743]
]
}
 

解决方案

放入资产文件。

对于Android的Studio项目需要主文件夹下创建的资产文件夹中创建项目。

阅读文件

 公共字符串loadJSONFromAsset（）{
        JSON字符串= NULL;
        尝试 {

            InputStream的是= getAssets（）开（file_name.json）。

            INT大小= is.​​available（）;

            byte []的缓冲区=新的字节[尺寸]

            is.read（缓冲液）;

            is.close（）;

            JSON =新的String（缓冲区，UTF-8）;


        }赶上（IOException异常前）{
            ex.printStackTrace（）;
            返回null;
        }
        返回JSON;

    }
 

然后你可以简单地阅读字符串这个函数返回为

 的JSONObject的obj =新的JSONObject（json_return_by_the_function）;

I have the following json file. I want to know where should i place the json file in my project and how to read and store it.

{
"aakash": [
    [  0.070020,0.400684],
    [  0.134198,0.515837],
    [  0.393489,0.731809],
    [  0.281616,0.739490]

],
"anuj": [
    [  1287.836667,-22.104523],
    [  -22.104523,308.689613],
    [  775.712801,-13.047385],
    [  -13.047385,200.067743]
]
}

Put that file in assets.

For project created in Android Studio project you need to create assets folder under the main folder.

Read that file as

public String loadJSONFromAsset() {
        String json = null;
        try {

            InputStream is = getAssets().open("file_name.json");

            int size = is.available();

            byte[] buffer = new byte[size];

            is.read(buffer);

            is.close();

            json = new String(buffer, "UTF-8");


        } catch (IOException ex) {
            ex.printStackTrace();
            return null;
        }
        return json;

    }

and then you can simply read this string return by this function as

JSONObject obj = new JSONObject(json_return_by_the_function);

Hope u will get what u want
