When i implement an ImageView the quality is very low and i cant choose between mipmap folders (xhdpi,mhdpi,xxhdpi etc.). The images are all in one directoy so i cant define in with src or background.

[Here a picture of my res directory](https://i.stack.imgur.com/HpPN3.png)

How can i achieve an imageview with a good resolution.? I tried several ways and it not seem to work out. I appreciate your help
