Native dialogs in Android are boring! if you are developing an app having some cool and customized theme then doing something about those dull dialogs is a must. They wouldn’t just compliment the overall look of your application. I faced this kinda scenario recently and while experimenting and trying different suggestions on forums, I finally got around it and made it to work!
First things first, as far as my experience went, AlertDialog is not going to help you here. It just don’t get rid of that black background that is there by default (talking about gingerbread dialogs here). No matter what you do, it’ll always show the black background from behind your image (if you have any). Anyways, to create a custom dialog, we need to create a layout first in a separate xml file. Here’s an example:
This is just a simple layout having a background image that has irregular borders. Now we just need to write a few lines of code in order to make it work:
Here, we are setting the background color to transparent in order to get rid of the default dialog background color. After that, we just need to assign the layout resource to the dialog and that gets the job done.
Notice the resultDlg.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND); This will remove the dim effect that makes your parent layout a bit darker. You can also set some additional flags like adding a blurred effect to the background/host activity from which this dialog is invoked. To do this, simply use the addFlags function with FLAG_BLUR_BEHIND flag. Here’s the exact statement:
This will create a very nice blur effect which I find more neat than the original dim effect. And that ends this post here. Feel free to comment and ask questions, I’ll try to answer them as swiftly as I can.
