I am making an app on android using kotlin and there's this tricky part where the admin has to load an image to the app , when that's done the background of the layout is set to that image , the image itself has these 4 or 5 red dots spread according to a blueprint. What I want to do is to detect where those dots are then put some components over them ( Button, TextView..). I know my question is a bit complex but i hope someone could help me because I don't even know where to start with this. Thank you.

I am stuck in app locker.
Pleas help me to figure out.
Here I use a background image in that there are 9 holes. I need to put images on each hold for password. I try much but each time images are not on the same places on different screens or display devices. Please give me some demo or tutorial. Thank you!
Actually I want to design like the below picture, where the background image is constant with holes, and I want to put on each hole with different pig image. But the problem is I don't know how to design layout for accurate pig position and another important thing is that if the display screen is different, does the layout design work?
I am developing an Android app and am a bit stuck on how I go about creating the layout I'm after. I said spotify-like (website not app) as I dont want the parallax effect. It's actually closer to http://www.poormet.com/.
What I have tested so far is a RelativeLayout with an ImageView and Listview (with transparent dividers) within it. This layout shows the image in the background between rows which is a step in the right direction. The issue is I'm at a loss as to how to get the images to change smoothly depending on what listrows are on screen.
Also, if I want to replicate the text over the images like poormet example mentioned above, then it seems to me I am going to have to have alternating transparent and not transparent rows.
Am I on the right track or am I approaching this problem the wrong way?
Any guidance will be greatly appreciated!!!
(also, please let me know if what I have described doesn't make sense - more than happy to clarify)
Actually, I got a little problem while building my Android App. I want to create a mini-game in my app. It will works like this:
At the begining an image appears
then the app ask the user to zoom-in the picture
then a grid will appear and seperate the picture into pixels (like the one million pixel wall for example)
the user will have to choose one "pixel" of the grid and he will win (or not) some points.
It seems quite simple but i got some issues:
How can i create this grid? (GridLayout? )
How can i put an invisible Grid (opacity=0) on a picture ? (Grid Layout Option Maybe ? )
How can i use the zoom-in option to be as smooth(natural and simple) as possible?
What should i do in order to turn the Grid opacity to 1 when "the Zoom in" effect has been done ?
I know that some several questions are likely answering to the grid problem but I need some personal advices in order to build my own game. General tips and tricks are welcomed. Explanations will be great.
Thanks in advance.
P.S.: Sorry for my English. It's not really my main language but I hope that I am still understandable.
Actually i've found The GridLayout.setalpha(alpha) Option so i know now how to build a grid and to manipulate his opacity.
I just Need now some informations about how to animate this grid with the zoom-in effect and the Zoom-out effect !
I want to create an image auto scrolling for an outer-space type of game. To make it more exact, I want to load 2 background image that uses a single image occupying the whole screen and auto-scroll it alternatively to create an animation that the background image is moving. Don't get confused with auto scrolling and and shifting to another image automatically. I really meant auto scrolling like moving background using 1 image.
I did some research but what I saw are segments of java codes that made me confused. If possible can anyone provide me an example? From loading the image from xml (should I use an imageview with this? or just set the background image of the layout?) and how I should process it in java code to make an image autoscrolling.
Any ideas guys? Thanks! Sorry for asking too much.
I am displaying an image gallery consisting of 15 images with image displayed on the screen (full-screen) at a time. When the user swipes across, the image changes. I am looking at a small polka-dots style indicator at the center-bottom of the screen to show the image count and where the user currently is.
eg: If my gallery held 5 images and the user was currently on the 3rd image, then there would be 5 polka dots with 3rd dot highlighted/filled with color and the rest polka-dots be hollow.
I know the description might sound a little vague but in short, I am looking at an image count indicator! :)
Thanks!

I know exactly what you want, you are looking for the PageControl that is used on iPhones with the Scroll Views. I have never seen anything like that for Android. You would have to build a custom view. It's explained here:
Building Custom Android Components
I finally found it in the Launcher code!
