Vector illustration, I have always known this thing, but I can't do it myself, I can only use it. It would be better if there are colleagues who can do it, so that the app can be thinner.
It doesn't matter if you can't make vector graphics, there are libraries, such as Ali's father's iconfont+ , but I only know this one that is easy to use.
Go to the home page and choose a picture to download, remember to choose SVG download
After downloading, select the drawable folder in your project, right-click->New->Vector Asset
Select Local file (SVG, PSD), then select the .svg file you just downloaded, then click Next and Finish
In this way, a .xml file is generated in the drawable folder, which is the vector diagram we want to use
see the effect
ImageView imageView = findViewById(R.id.image_view); imageView.setImageResource(R.drawable.ic_smile);
