Android has a lot of special xml files, such as commonly used selector, style, and shape. proficient in using these xml files can make our project morePersonalization.

1. Sub-tags (corners, gradient, padding, size, solid, and stroke)

First, let's take a look at all the attributes of gradient.

All attributes do not need to be set every time. custom settings are made based on three gradient types. The following shows the effects of the three gradient types.

 

2. Shape attributes

We have discussed the role of the Shape sub-label above, but the Shape itself has not been discussed yet. The Shape itself can define the Shape of the current Shape, and the Shape can draw four types of images, respectively: rectangle, oval, line, and ring ).

The following shows the effects and codes of the four images.

The line has no height, so no matter how high the control is set, only one line is displayed. The color cannot be set. The width can be displayed based on the control width.
