Answers: From Android Developers I saw that there is no tag for Bitmap XML that allow you to change it size. You need to do this via some Graphic Applications like GIMP. As @Kevin Cooper told already, ideally you need to create different sets of resources (with different sizes) for different screen types Resize images in bitmap in xml, The ImageView looks like this in res/layout/activity_main.xml : You often want to resize a bitmap but preserve the aspect ratio using a BitmapScaler utility class There are several types of drawables in Android including actual bitmaps, nine-patch, and XML files. Try wrapping your image file with an XML file that. An XML bitmap is a resource defined in XML that points to a bitmap file. The effect is an alias for a raw bitmap file. The XML can specify additional properties for the bitmap such as dithering and tiling. Note: You can use a <bitmap> element as a child of an <item> element

5. When you set the Drawable of an ImageView by using the setBackgroundDrawable method, the image will always be scaled. Parameters as adjustViewBounds or different ScaleTypes will just be ignored. The only solution to keep the aspect ratio I found, is to resize the ImageView after loading your drawable Haven't tried to do exactly what you want, but you can scale an ImageView using android:scaleType=fitXY and it will be sized to fit into whatever size you give the ImageView.. So you could create a FrameLayout for your layout, put the ImageView inside it, and then whatever other content you need in the FrameLayout as well w/ a transparent background ImageView.ScaleType | Android Developers.

public static Bitmap createBitmap ( Bitmap source, int x, int y, int width, int height, Matrix m, boolean filter) Added in API level 1. Returns an immutable bitmap from subset of the source bitmap, transformed by the optional matrix. The new bitmap may be the same object as source, or a copy may have been made Step 1: Create a new project in Android Studio and name it ImageViewScaleTypes. Step 2: Open res -> layout -> activity_main. xml (or) main. xml and add following code: In this step we open an xml file and add the code for displaying an image view and different button on the screen in a relative layout

You can create a BitmapDrawable from a file path, an input stream, through XML inflation, or from a Bitmap object. It can be defined in an XML file with the <bitmap> element. For more information, see the guide to Drawable Resources Bitmap File: For bitmap graphic file. Nine-Patch File: For PNG file with stretchable regions. Layer List: For drawn in array order, creates a LayerDrawable. State List: Use XML file for various bitmap graphics. Level List: An XML file that defines a drawable that manages a number of alternate Drawables. Transition Drawable: Use to cross-fade between two drawable resources This example demonstrates how do I convert Bitmap to drawable in android. Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project. Step 2 − Add the following code to res/layout/activity_main.xml. Step 3 − Add the following code to src/MainActivity.java Note: The fitXY scale type allows you to set the exact size of the image in your layout. However, be mindful of potential distortions of the image due to scaling. If you're creating a photo-viewing application, you will probably want to use the center or fitCenter scale types.. Refer to this ImageView ScaleType visual guide for additional reference..

A NinePatchDrawable graphic is a stretchable bitmap image, which Android will automatically resize to accommodate the contents of the View in which you have placed it as the background. An example use of a NinePatch is the backgrounds used by standard Android buttons — buttons must stretch to accommodate strings of various lengths If you want an ImageView that both scales up and down while keeping the proper aspect ratio, add this to your XML:. android:adjustViewBounds=true android:scaleType=fitCenter Add this to your code: // We need to adjust the height if the width of the bitmap is // smaller than the view width, otherwise the image will be boxed. final double viewWidthToBitmapWidthRatio = (double)image.getWidth. Bitmap File: A bitmap graphic file. Android supports bitmap files in three formats: .png, .jpg, .gif.

  1. There are a number of reasons why loading bitmaps in your Android app is tricky: Bitmaps can very easily exhaust an app's memory budget. For example, the camera on the Pixel phone takes photos of up to 4048x3036 pixels (12 megapixels). If the bitmap configuration used is ARGB_8888, the default for Android 2.3 (API level 9) and higher, loading a single photo into memory takes about 48MB of.

  5. Android 12 is now breaking foreground services in backgrounded apps and looking for feedback. I just think this is a very important change they are forcing developers to use WorkManager 2.7 now if you target android 12. So to future proof your app it might be time to look into it if you have services doing important background work
  6. The objectAnimator element does not expose a target attribute, however, so you cannot set the object to animate in the XML declaration.
