Android provides various methods for parsing JSON data, here are two common options:<\/p>\n

    \n
  1. Use the JSONObject and JSONArray classes.<\/li>\n
  2. First, convert the JSON string to a JSONObject object, for example: String jsonString = “{‘name’:’John’, ‘age’:30, ‘city’:’New York’}”;
    \nJSONObject jsonObject = new JSONObject(jsonString);<\/li>\n
  3. Next, you can retrieve the corresponding value using keys like this:
    \nString name = jsonObject.getString(“name”);
    \nint age = jsonObject.getInt(“age”);
    \nString city = jsonObject.getString(“city”);<\/li>\n
  4. If the JSON string contains an array, you can use the JSONArray class to parse it. For example:
    \nString jsonString = “{‘students’: [{‘name’:’John’, ‘age’:20}, {‘name’:’Kate’, ‘age’:22}]}”;
    \nJSONObject jsonObject = new JSONObject(jsonString);
    \nJSONArray studentsArray = jsonObject.getJSONArray(“students”);
    \nfor (int i = 0; i < studentsArray.length(); i++) {\n JSONObject studentObject = studentsArray.getJSONObject(i);\n String name = studentObject.getString(\"name\");\n int age = studentObject.getInt(\"age\");\n \/\/ Process data for each student\n}<\/li>\n
  5. Using the Gson library:<\/li>\n
  6. First, add the Gson library dependency in the build.gradle file: implementation ‘com.google.code.gson:gson:2.8.6’<\/li>\n
  7. \nNext, you can use the Gson library to convert a JSON string into a Java object, for example: String jsonString = “{‘name’:’John’, ‘age’:30, ‘city’:’New York’}”;
    \nGson gson = new Gson();
    \nMyClass obj = gson.fromJson(jsonString, MyClass.class);<\/li>\n
  8. MyClass is a custom class where its fields need to correspond to the keys in a JSON string. For example: public class MyClass {
    \n private String name;
    \n private int age;
    \n private String city;<\/p>\n

    \/\/ Constructor and getter\/setter methods are omitted
    \n}<\/li>\n<\/ol>\n

    The above are two common ways to parse JSON, choose the suitable method for parsing according to the actual situation.<\/p>\n","protected":false},"excerpt":{"rendered":"
