Implementation code of mutual conversion between Android picture types

This example describes the implementation code of mutual conversion between Android image types. Share with you for your reference. The details are as follows:

Android will perform some types of conversion when processing image resources. Now I have time to sort it out:

1、Drawable → Bitmap

The Java code is as follows:

2. Get bitmap from resource

The Java code is as follows:

3、Bitmap → byte[]

The Java code is as follows:

4、 byte[] → Bitmap

The Java code is as follows:

The above are some transformations I have encountered in practice. If I encounter similar ones in the future, I don't have to look everywhere.

I hope this article will be helpful to your Android program design.
