Images for screens with different pixel densities
If you need to add separate images to the resources for screens with different pixel densities,then this is done in the style of iOS, i.e. '@< density >x' is appended to the filename. For example
image@2x.png image@3x.jpg image@1.5x.gif
For example, you have images for three densities: image.png, image@2x.png, and image@3x.png.In this case, you only assign the value "image.png" to the "src" field of the ImageView.The library itself will find the rest in the "images" directory and transfer the image to the client with the required density
