BaseToolbarActivity就是实现了这个⽅法，对contentView进⼀步包装后再返回。
在这个类内也可以封装loadingDialog，Toast什么有关View的基础功能。mvp
同时在写具体业务的Activity或者Fragment时，不需要重载什么新的⽅法，只需要传⼀个泛型ViewBinding就可以了，减少写代码的负担。

主要代码：
public abstract class BaseFunctionsActivity<VB extends ViewBinding> extends BaseViewActivity<VB>
{
public static ArrayList<Class<? extends BaseActivityFunction>> functionsClasses = new ArrayList<>();
private LinkedHashMap<String, BaseActivityFunction> functions = new LinkedHashMap<>();
@Override
protected void onCreate(Bundle savedInstanceState)
{
for (Class<? extends BaseActivityFunction> functionClass : functionsClasses)
{
try
{
functions.Name(), wInstance());
}
catch (IllegalAccessException | InstantiationException e)
{
e.printStackTrace();
}
}
for (BaseActivityFunction baseActivityFunction : functions.values())
{
}
}
@Override
protected void onNewIntent(Intent intent)
{
}
@Override
protected void onSaveInstanceState(@NonNull Bundle outState)
{
for (BaseActivityFunction baseActivityFunction : functions.values())
{
}
}
@Override
protected void onStart()
{
for (BaseActivityFunction baseActivityFunction : functions.values())
{
}
}
@Override
protected void onRestart()
{
for (BaseActivityFunction baseActivityFunction : functions.values())
{
}
}
}
@Override
protected void onResume()
{
for (BaseActivityFunction baseActivityFunction : functions.values())        {
}
}
@Override

{

}
@Override

{

}
@Override

{
Iterator<BaseActivityFunction> iterator = functions.values()
.iterator();
while (iterator.hasNext())
{
BaseActivityFunction baseActivityFunction = ();
baseActivityFunction = null;

@Override
