private P mPresenter;

protected abstract void initLayout(@Nullable Bundle savedInstanceState);

protected abstract P setPresenter();

protected abstract void initViews();

protected abstract void initData();


@SuppressWarnings("SameParameterValue")
protected <T extends View> T $(@IdRes int viewId) {
return findViewById(viewId);
