Custom view with button in ArrayAdapter

October 12, 2013 at 10:58 pmCategory:Android

I have defined a custom view (xml) for my ArrayAdapter for a ListView, which adds a Button. I’d like to create an OnClickListener for this Button per row, yet without creating a custom adapter. Is that possible, or does Android force me to create a custom ArrayAdapter for my ListView?

Here’s a snippet of what I’m doing:

Now I’d like to add an OnClickListener for the Button in my custom view.

Thanks in advance,

You have to implement you own Adapter & in getView() method set OnClickListener on your button. Here kick off example:

Get image code from url with Javascript

September 27, 2013 at 10:52 amCategory:JavaScript

I\’m creating image uploader for my website. I figured out how to upload image from computer & wrote the whole processing script; Now I need to add an option to upload an image from web. My script works fine after the image is converted into 64 bit format:

Looks like it is impossible to do anything helpful with image before it is on my server, so I have this script which creates a temporary copy of the image on my host:

So, what I need to do is to take a link \”image.png\” in JavaScript & transform it to 64 bit format to apply further actions in JavaScript. I can\’t find a solution anywhere, can someone help?

Please take a look at this thread, where a complete solution to convert an image to base64 is provided. This requires HTML5 tho, so your client needs a relatively up-to-date browser.

There seems tho to be some issues between the browsers, since they process image data differentely. If you want 100% the same Base64 encoding as your PHP-script, I suggest you simply make an AJAX-call to the script, which processes the image. Then it returns the Base64 string.
