技術標籤：Androidgson陣列

以下方法只是提供參考

• 當一個list中包含不同型別時，可使用以下方法解析

[
   {"name":"法外狂徒張三","age":33},
   "123",
   123,
   12.3
]

• 直接上程式碼

public class MainActivity extends AppCompatActivity {

    private static final String TAG = "json";

    /*[
	{"name":"法外狂徒張三","age":33},
	"123",
	123,
	12.3
    ]*/
 

    private static final String strJsonData = "[\n" +
            "\t{\"name\":\"法外狂徒張三\",\"age\":33},\n" +
            "\t\"123\",\n" +
            "\t123,\n" +
            "\t12.3\n" +
            "]"
 
;

    static class InfoBean {
        public String name;
        public int age;

        @Override
        public String toString() {
            return "InfoBean{" +
                    "name='" + name + '\'' +
                    ", age=" + age +
                    '}'
 
;
        }
    }

    private List<Class> typeList = new ArrayList<>();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        typeList.add(InfoBean.class);
        typeList.add(String.class);
        typeList.add(Integer.class);
        typeList.add(Float.class);

        JsonArray jsonElements = JsonParser.parseString(strJsonData).getAsJsonArray();//獲取JsonArray物件
        for (int i = 0; i < jsonElements.size(); i++) {
            JsonElement jsonElement = jsonElements.get(i);
            for (int j = 0; j < typeList.size(); j++) {
                try {
                    Object bean = new Gson().fromJson(jsonElement, typeList.get(i));
                    if (bean instanceof InfoBean) {
                        Log.i(TAG, "InfoBean.class->" + bean.toString());
                    } else if (bean instanceof Integer) {
                        Log.i(TAG, "Integer.class->" + bean);
                    } else if (bean instanceof String) {
                        Log.i(TAG, "String.class->" + bean);
                    } else if (bean instanceof Float) {
                        Log.i(TAG, "Float.class->" + bean);
                    }
                    break;
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        }
    }
}
