hello, chike!

how can I help you today?

Hi Mark!

My question is about Dagger 2 Scopes

I have never used Dagger

oh

so, I will not be able to help you with that particular library

sorry!

so what do you use for DI then?

I don't use DI

ok Mark! maybe next time I will come up with another question

thanks

hi

OK, sorry I could not be of greater use

wuqiang: hi! it's your turn -- do you have a question?

yes i have

i am coding a chat app

i want click a button then on my layout popup a view

how can i do that ?

what do you mean by "popup a view"?

do you mean that you want to have a dialog box over your activity?

just like the app " WhatsApp" when you select a picture

sorry, but I do not use WhatsApp

just like any kind of chat app ,when you select a picture

I do not use chat apps on Android

let my have a picture for u

i have uploaded a picture

did you upload it into the chat?

ah, there it is

OK, so when the user clicks the paperclip, what are you expecting to happen?

specifically, that looks like a BottomSheetDialog

I have not used this personally

in there, they either are using a RecyclerView with a GridLayoutManager or a GridView, I guess

also have another situation

that looks like some sort of emoji keyboard

yes

regardless, that too is probably a RecyclerView with a GridLayoutManager, or perhaps a GridView

pageView

if you mean ViewPager, that may wrap around the RecyclerView or GridView

it can swip to right or left ot select another part

most likely, that is a ViewPager, with grids for the pages

on every paveView have a recyclerView

correct

presumably, that is some sort of tab strip

thanks

how to pupup this kind of View with a button ?

as I indicated, I would look into BottomSheetDialog

pop-up

thanks

that's a wrap for today's chat

the next chat is Friday at 9am US Eastern

the transcript of this chat will be posted at https://commonsware.com/office-hours/ shortly

have a pleasant day!
