Yandex Translate, List Pickers & Country Flags

Here’s the source code to accompany this series of video tutorials:

Start Up

When the app loads three lists are created, data are added to them and the list pickers are populated:

Show Flags

To reduce repetition, a procedure called showFlags is created to grab flag images from The flagFrom and flagTo variables will be updated every time the user picks a language from the list picker.


Pick Languages

Hi there - that was quick! :smile: Welcome to the community - can you share a screenshot of the blocks you are currently using so that I can point you in the right direction?


. Sir i have not completed yet but when click on button then screen 2 open where there is lisr view

i have just done this in screen 2 after picking from list view

Sir i just want list view instead of list picker i want it works the same way asu told in the video

But I don’t really think you need two screens for this, as your app will be a lot slower having to go back aand forth between screens so often. Why not use your buttons to toggle the visibility of your listView? This way everything can be kept on the same screen.

Sir can u tel me how to make offline translator with photo translate feature
