在OK請求完成之後:

handler.post(new Runnable() {
    @Override
public void run() {
        Class<Object> genericUtil = GenericUtil.getGenericUtil(okCallback.getClass());//運用GenericUtil類返回泛型資料
Object o = GsonUtil.getGsonInstence().fromGson(string, genericUtil);//Gson解析
okCallback.onSuccess(o);   //返回資料
}
});
 

介面:

public interface OKCallback<T> {
    void onSuccess(T t);
void onFalsed(Exception e);
}

接收資料,實現的介面:

public abstract class OKEntityCallback<T> implements OKCallback<T>{

    protected Class<T> cla;
public OKEntityCallback() {
        this.cla = GenericUtil.getGenericUtil(this
 
.getClass());
}
}

資料回撥,泛型轉換:

public class GenericUtil {
    public static <T> Class<T> getGenericUtil(Class<?> cla){
        Type genericSuperclass = cla.getGenericSuperclass();
Class<T> result = null;
if(genericSuperclass instanceof ParameterizedType){
            ParameterizedType 
 
parameterizedType = (ParameterizedType) genericSuperclass;
Type[] types = parameterizedType.getActualTypeArguments();
result = (Class<T>) types[0];
}
        return result;
}
}

最終回撥資料:

OKHttpUtil.getInstence().get(path, new OKEntityCallback<OKTestBean>() {   //泛型先加上,再重寫回家介面的方法
    @Override
public void onSuccess(OKTestBean okTestBean) {
        Log.e("Test",okTestBean.toString());
}

    @Override
public void onFalsed(Exception e) {
        Log.e("Test","NO");
}
});
