我用fragment请求网络会报错 ，请问怎么解决 about mvparms

[JessYanCoding]

.compose(((BaseActivity) mRootView).bindToLifecycle())

你的view接口是用fragment实现的,这里你强转成activity所以强转失败,复制下面的替换之,这段代码的意思是将生命周期绑定到和fragment的声明周期一样,如果fragment,被关闭,这个网络请求也会结束,规避了内存泄漏的风险
.compose(((BaseFragment) mRootView).bindToLifecycle())

附送个工具类

---

public static LifecycleTransformer bindToLifecycle(BaseView view) {
if (view instanceof BaseActivity) {
return ((BaseActivity) view).bindToLifecycle();
} else if (view instanceof BaseFragment) {
return ((BaseFragment) view).bindToLifecycle();
} else {
throw new IllegalArgumentException("view isn't activity or fragment");
}

}

用法
.compose(bindToLifecycle(mRootView));
