将文件中读取的字符串转换为JSONObject android

File file = new File("文件路径");
StringBuilder stringBuilder = new StringBuilder();
try {
    BufferedReader bufferedReader = new BufferedReader(new FileReader(file));
    String line;
    while ((line = bufferedReader.readLine()) != null) {
        stringBuilder.append(line);
    }
    bufferedReader.close();
} catch (IOException e) {
    e.printStackTrace();
}
String jsonString = stringBuilder.toString();

try {
    JSONObject jsonObject = new JSONObject(jsonString);
    // 可以通过get方法获取JSONObject中的数据
    String value = jsonObject.getString("key");
} catch (JSONException e) {
    e.printStackTrace();
}
