Is there a way to set image to checkbox from prepopulated sqlite database? Or somehow connect checkbox to an image from database. The problem is that I have to shuffle images from database, and the user needs to select two of 5 images using checkbox (or some other way, but I've come up with nothing but checkbox idea). If I did not have to shuffle images I would simply put a checkbox below every image and I would know what image is selected when I user check a box, but this way I would not know where my images are.
See this: http://vikaskanani.wordpress.com/2011/07/20/android-custom-image-gallery-with-checkbox-in-grid-to-select-multiple
and this How to save images into Database to get a image bitmap from stream.
you can use a adapter to set bitmat into each image in gallery.
I hope this could help you.

I have a long list of images that i need to show in to recyclerView. I am using glide to show the images from my adapter.
Glide.with(context).load(feed.getImgLink()).diskCacheStrategy(DiskCacheStrategy.NONE).into(holder.myImgView);
The above is the code am using i set the DiskCacheStrategy to none because I'm trying to show Instagram like Feed and i didn't want to permanently cache the img on disk.
The first time i see the image there is no problem it is displayed normal but after i scroll down and back up the image reload again. I get that i haven't cache the image in to disk but there is still momery cache.
Is there any way i can solve i could use diskcache to ALL but it is taking space for just one time viewing.
Try this.
Glide.with(context).load(imageUrl).into(holder.myImgView);
I have a problem, I want to show one image in ImageView, but I want to give user options to choose from list image (maybe put text somewhere in there).
and maybe save it on firebase database, so when user reopen/restart the app, that image user choose/select before will show somewhere in their profile/activity.
so far I've tried RadioButton, CheckBox, Spinner.
and non of them work, maybe I don't know implement it properly.
I'm hoping someone help me solve this, it's help a lot.
thanks.
I am trying to create a custom gallery with a single select option. I've used the code provided by google docs to create a GridView that contains the images contained in drawable.
Now I want to change it by making the GridView show all the images stored in the phone.
To get all images from the phone you need to query the android.provider.MediaStore
First make sure you have the AndroidPermission.READ_EXTERNAL_STORAGE, then get the thumbnails for the grid.
Here is a simple way to do this:

Hope this helps.
I am trying to insert multiple images in one editText. I have used following code to attach image to EditText
txt = (EditText)findViewById(R.id.text);
Bitmap bitmap = BitmapFactory.decodeFile(attach);
Drawable drawable = new BitmapDrawable(bitmap);
txt.setBackgroundDrawable(drawable);
But the problem is it only attach one file and show, If i used array then only the last image is only show. at any how it only shows one Image. Is there any way to show multiple images in one Editbox. Thanks in advance.
Because you can only have one background.... if you want more then there is a layer Drawable which you can use and also you can put the button in a frame layout and add a couple of imageViews below/over it for the rest of the images.
But the best solution will probably be instead of having a couple of bitmaps to just make a single one in Photoshop or equivalent photo editing app and place that one.
According to docs: http://developer.android.com/reference/android/view/View.html#setBackgroundDrawable(android.graphics.drawable.Drawable)
You are not able to provide more than one Drawable item in argument
And I don't know if you understand what is .setBackgroundDrawable(d) method purpose, but it is not meant to be used for displaying images inside text but to set Background of EditText View.
So you're not inserting images in EditText but setting its background,
look for some Rich Text Edit components usable for Android
such as http://code.google.com/p/android-richtexteditor/
or others..
You can probably use a LayerDrawable with the constructor LayerDrawable(Drawable[] layers) to chain together several images and display them as an EditText's background, though as Marek said, I suspect you're looking for something other than setting images in the background.
I have a ListView, displaying some items, containing an ImageView filled with a standard image at first and a line of text.
What I wanna do is downloading one thumb after another with an AsyncTask and step for step change the standard image with the downloaded one. How to realise this?
The ListView contents are managed by an enhanced ArrayAdapter.

If I understand you correctly you're interested in a LazyList. This example shows a stub for the image, then downloads some thumbnails as the user scrolls down and caches these onto an SD card. The next time the images will be loaded from the SD card.
Lazy load of images in ListView
I personally used Fedor's example and it worked well.
