I need that when clicking on an image generated within the code (I created it using XUIViewsUtils.CreateB4XImageView), any instruction is executed (for example, changing the value of a variable). The drawback is that when creating the imageview through code, I don't have a pre-written code on the imageview_click routine. How do I achieve this? This is necesary for B4i, B4J and B4A.

B4XImageView does not expose a click event routine. You will need to overlay it with a transparent Pane(l) and create the Click event routine of the latter.
B4XImageView no expone una rutina de evento de clic. Deberá superponerlo con un Panel transparente (l) y crear la rutina de evento Click de este último.
Lucams, thanks for your response, ok, so now i change the imageView for a button created using code. The question is, how can I modify a variable by clicking on the new buttons created. I need to create 100 buttons, and depending on which button I press, a variable is going to change its state. What I don't know is how to relate a code to modify a variable to the click event of that new button created by code.
You can use an ImageView in all three platforms, but you need to treat the Click event differently in B4J.
Can you post a small test project showing the problem ?

LucasMs, So much thanks, I had already used the sender variable in a custom list but I didn't know that it could also be used in this way. Finally what I did was create an array of buttons "Dim button(100) As BUTTON" and to differentiate each button I assigned the respective consecutive to the tag in the For routine of creation of the 100 buttons as it is created, as you indicate.

Klaus, You're right, the routine that works for imageview click in B4J is "iv_MouseClicked", but this only works with ImageViews created from the designer. Those that are created with code do not respond as indicated by LucasMs. Therefore, I will try to use buttons since these do work and the "Button_Click" event is common to all 3 platforms, later I will add images to each button and I hope that the result will look like I need it.
