I am hoping to build an image selector/de-selector in an Android app.
So far I have been able to use an image view, and display the selected image, and put a button next to the image view to deselect the image.
However I am hoping to overlay some sort of a remove button, to make it look pretty and concise, however I am trying to avoid an overlay button as such.
Any ideas please.
Secondly, I would like to filter out only certain file types.
Thanks

Trying to make my application give a cooler look am thinking of this. The user clicks a button on an xml and as a result of this a dynamic image gallery viewer comes in front of the user. Like we have in iphone for changing songs. It could include an arrow to the left and right for the user to see the next or previous picture or the user can just use the finger to move to the next picture. I hope am sketching the right picture to the experts here. is it possible to have such a view in android?can i get any running examples?
you can use the gallery option or view flipper
for gallery try this link

for viewflipper

I have list of images. what i want that when user clicks on one of the images then it should appear similar like following picture. user can see big image with blur background, and user can change this image by swiping finger(same like activity change). when user press back button it should be cancel. Is it possible in Android? I hope you understand my problem.
yes,you must define a customize dialog, and then open it when you want.
you can code for swipe finger or anything else you are looking for.
making and showing custom dialog here and as some guidance to you, use image view and you must use gesture detector here or here
enough ??
What's a good way, both layout- and codewise, to accomplish the following:
Display one or more clickable images on the screen.
By default, the images are default images (duh)
When clicking on them, they change to a specified image
When clicking again, the change back to the default image
I cannot set all the images in the xml layout file(s), since I must be able to programatically set and change the images when clicking, and keep a record of the images on display etc.
In case anyone wonders: Yes, this is supposed to be a simple "memory" game, where I show x images, and click on two of them to display them, and give a result if they're identical.
I would suggest you to use ImageSwitcher, as the view, and setOnClickListener on the ImageSwitcher, to apply image changes on click action.
(I am an extreme newbie, my knowledge is of basic programming ideas, i.e. a click executes a command, basic cause and effect)
I am wanting to test out a simple idea of having an image (for example sake imagine one page of "Where's Waldo!?") where you open the app and you have an image, (also this is aimed at android tablets) and this image has many details and lots of different focal points going on, so i want the end-user to be able to look through this image and see, (again for example sake) waldo, and then to be able to click on waldo and a text bubble to pop up with "you win!
" or some info about waldo, or any other details on the page.
so far all i have been able to do is make the entire image one button, which is undesirable seeing as i would prefer there to be about 20-30 randomly placed buttons each with their own synopsis of the section of the image being clicked on.
using android app inventor...
A site explaining how to make specific parts of an image into clickable areas can be found here...it worked for me..
The link is also summarized at this SO question.
How about add a small 'Buttons' on the image with transparent background and make sure you add button after image so that it will not be covered by image. Then try and see if you get onClick when you hit button. If this works, may be you can have such multiple buttons over image and user will not notice that he is actually hitting button instead of image.
A button with a transparent background will surely work.
<Button
android:layout_height="50dip"
android:layout_width="50dip"
android:background="#00000000">
</Button>
I am trying to make a really easy xml layout and I can't seem to get it to look the way I want.
I attached a picture of what I want it to look like:
Basically, I have a static background image in my imagebutton at the top. Below that I have a picture the user snapped in the Photo Box. I assume I need an image view for that, but would it be possible for me to instead pass the pic to the background of an image button too so I can make the size easier to manage?
Based on what the user chooses in the options before this layout, an option photo is shown based on what they select. The photo would display to the right of the centered image, if that option is selected.
Below that would be a centered text view, with another separate one below that. Finally, I would have two buttons on top of each other at the very bottom.
Could someone show me a good way to get this layout and also tell me if it is possible to take a picture that is snapped and make it the background of an image button - or if that is a bad idea?
Thanks so much!
Seems like for the most part, you just want a simple LinearLayout. For the part with the photo, you could use an embedded LinearLayout or RelativeLayout.
As for the picture - you can easily set the background of any view or view group to any image (any view has an option to set the drawable for the background).
The only thing you should consider - for the purposes of making the UI more intuitive - is to slightly modify the image for the different states (focused, selected, etc), so that the user gets visual feedback when selecting the button via the trackpad, or when clicking on the button. A "drawable" has built-in support for multiple images for each state.
