Android custom button style "very common"

Let's see one today. Dynamically implement some effects by rewriting the button, such as rounded rectangles, circles, pressed font changes, background color changes, background images, etc.

To illustrate this, this implementation is absolutely not unique, and can be implemented simply through an XML file, only to make the style of the control completely code-ready and easier to package and apply to other projects

Here are a few pictures:

Figure 1 Initial state Figure 2 Press the TEXT0 of the first line

Figure 3 Press the second row of TEXT1 Figure 4 Press the third line of TEXT2, hold down the screen, there is no hint to toast

Here's a look at the code, a total of two classes, a layout file

1 Buttonm.java: Rewrite button, can be individually packaged and applied to other items

Gets the width of the screen, four button per line, with a gap of 60 total 300, except 4 for each control width


@SuppressWarnings ("deprecation")

Define the first layout

Font Color

Background color

Selected Background color

Text hints

Comments are basically explained, you can slowly accumulate these controls, and eventually form a control library of their own, in different projects to improve, make it more and more powerful





I'll tell you about it tomorrow. By inheriting relativelayout, implementing multiple control combinations that allow different projects to be applied, you can avoid rewriting the
