这里我们传入的是 DataModel 的实例,而 MainPresenter 类是继承自 BasePresenter 基类的,所以在 BasePresenter 的反射代码中的 this 指的就是 MainPresenter 类的对象。看如下反射代码:
反射代码部分:
//通过获得泛型类的父类,拿到泛型的接口类实例,通过反射来实例化 model
ParameterizedType type = (ParameterizedType) this.getClass().getGenericSuperclass();
Log.d("===========", "attach: "+this.getClass().getSimpleName());
if (type != null) {
Type[] types = type.getActualTypeArguments(http://www.amjmh.com/v/BIBRGZ_558768/);
try {
mModel = (M) ((Class<?>) types[1]).newInstance();
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (InstantiationException e) {
e.printStackTrace();
}
}
