So in my application, I'm using the system wallpaper as the background.
I'm doing so with the following code -
WallpaperManager wallpaperManager = WallpaperManager.getInstance(getActivity());
Drawable wallpaperDrawable = wallpaperManager.getDrawable();
view.setBackground(wallpaperDrawable);
The problem is, the background is trying to squish inwards. In other words the system image is trying to fit the whole image in one bit and it looks weird. How can I stop the background from resizing itself?
More info, on my homescreen, the wallpaper would be a picture of a car, you can only see the front part of the car. But when you open my app, you can see the full car but its squished and resized.
How can I go about doing this?
Perhaps this would help (from the WallpaperManager Class page):
wallpaperManager.suggestDesiredDimensions(int minimumWidth, int minimumHeight);

I would like to design a layout containing an imageview and a background view with two special effect. First is where the main imageview gets transformed with faded towards the vertical edges and second is a background imageview with a blurred effect like the image
The result that i am able to achieve
I saw this post for my first effect and currently using it, but it does not work when I change my phone into dark mode so I am not getting a perfect solution.
And the second special blur effect that i am able to achieve is far way different from what i want to achieve. The required blur effect has some hardness of the different shades of color and mine one is quite smooth. For my blur effect I am using the below code and I am using the library Fresco for my image.
ImageRequest request = ImageRequestBuilder.newBuilderWithSource(Uri.parse(imageUrl))
.setPostprocessor(new IterativeBoxBlurPostProcessor(60)).build();
PipelineDraweeController controller = (PipelineDraweeController) Fresco.newDraweeControllerBuilder()
.setImageRequest(request)
.setOldController(backgroundImage.getController())
.build();
backgroundImage.setController(controller);
Can anyone please suggest me any good solution or any good library for it or some code sample that can help me to achieve what I want.
The point to note here is the blurred background is an extension of the image itself. So if the left side of the screen has a purple hue the blurred region at the top left will be purple as well.
YOu can use a library like Blurry where it blurs the contents of the screen and then set that as a background. You can control the amount of blur you want.
Once you get the blurred image set it as the background of the container layout and set the picture in front
eg:
val bitmap = Blurry.with(this)
.radius(10) // make it more if you want the lue to be more
.sampling(8)
.capture(findViewById(R.id.right_bottom)).get() // get the view you want to blur
imageView.setImageDrawable(BitmapDrawable(resources, bitmap)) // set the value to the background
I want to have a splash screen, something like a full picture, which doesn't crop in heigth or width on different smartphone screens.
Now I achieved a splash screen with android:scaleType="fitXY", but now the image is cropped on top or bottom or if the devices screen size changes to another aspect ratio it is cropped on the left and right.
What do I have to do? I've already read the android developer article Supporting Multiple Screens, but I don't get it how to achieve this.
A simple picture in the middle of the screen is just simple to get, but a picture which fills the screen is hard to get. Can you help me pls?
you should use center_crop per this purpose. From the doc
Scale the image uniformly (maintain the image's aspect ratio) so that
both dimensions (width and height) of the image will be equal to or
larger than the corresponding dimension of the view (minus padding).
There is no way to create one single asset and expect it to do not be cropper and to do not create black areas when the application is deployed in different screen sizes.
The android platform is designed to work dynamically with multiple screen sizes that any manufacture can change at any time, including new resolutions that you haven't thought about it yet.
Android can specify minimums for screen hight/width categories in which your resources will fall, but those are generics.
In order to use them, you will have to specify qualifiers in your drawables and create a different splash screen for every qualifier, as for example if you use drawable-w420dp, all the resources there will be used when the screen has a minimum width of 420dp (notice that are not pixels)
So you have two options:
You can use one single splash image and design margins of that image flexible enough in order to cope with the image being cropped in certain cases. You can play with different scaleTypes in your ImageView and take as a reference this website http://etcodehome.blogspot.co.uk/2011/05/android-imageview-scaletype-samples.html even though as commented before, "center-crop" will be your best shot.
You can programatically use a specific image for a specific resolution.
2.1 Put in the assets directory, all the splash images that you want for all the specific resolutions or aspect ratios that you want to use
2.1 Get the screen size of the device with Get screen dimensions in pixels
2.2 Now you can load from the assets the image that you want dynamically
Use the below code
android:layout_width="match_parent"
android:layout_height="match_parent"
which will fill the entire screen.
Try Using Width and Height of image to "match_parent"
I'm getting stuck at a certain part of my app.
In my app, I have a few icons. The icons are completely white with transparent backgrounds. Is it possible for the user to set the colour of the icons without messing up the transparency? I tried searching a lot, but couldn't come up with anything. Could someone help me out?
Also would it be possible for the user to set custom icons from any folder as per their choice?
Thanks.
Yes it's possible. You have to create bitmap from resource How to set a bitmap from resource, then search bitmap for white pixels and change them to desired color (pix - by pix), then just set result bitmap as button or other layout element bitmap.
Developing an app for Android and I'm required to have a fullscreen image rotate (spin around infinitely, pivoted at the centre of the screen) in the background.
I have tried rotating the ImageView using RotateAnimation which works well, except the image is cropped to the size of the parent view.
I have also tried expanding the parent view to a set size (750dp) but it doesn't work well across all the different screen sizes.
Does anyone know of an easy way to implement this, which would involve scaling to uniformly fit the screen size?
Cheers,
Dylan
Screenshot of the image:
I have a background image of size 720x1280 for larger screen phones like the LG Nitro P930. However, when I have an application that displays this image, it doesn't cover about half an inch at the bottom of the screen. The image looks fine on normal and small screen sizes, and I have included all of the support screens in my manifest file.
Is there something that I can do that will allow me to stretch the image to fit the screen, or am I doing something wrong?
add android:scaleType="fitXY" and fill_parent for height and width both in you layout xml
You don't have to use image view background should work fine, are you using a scroll view per chance somewhere?
I figured it out. It was actually a setting on the phone that optimizes the application.
