Android Question Declaring members in Activity

You need to give us more information. Why do you need all these variables? What do they hold?

I can only guess that you should use a data collection such as a Map or List.

Hi Erel, I am developing an APP which communicates to ESP8266. However my APP has 100 plus Buttons to send various commands to ESP8266...
These buttons are not distributed to different layouts. You can assume 20 buttons on Layout 1, 30 buttons on Layout 2 etc...
Now, my APP includes home page and has option to open layout. Say there are buttons having caption "Open Layout 1", "Open Layout 2" etc...
Based on option selected by home page, I am loading layout in one Activity model. I must declare all members in Global sub of the activity so there are 100 plus lines in Global sub. I would like to avoid the same.
Hope I could explain my project background.
Please be free and ask if any further details are required.

I would never add 100 variables for the buttons. There are better ways to organize the references.

You can for example add the information you need to the buttons Tag property, set the event name of all these buttons to be the same and use the Sender keyword to get the button that raised the event.

Hi Erel,
Thanks. It worked after watching video.
