tintԴ??
直播源码网站,自定义平台界面,源码完成各项内容更改
添加依赖:
引入MaterialButton库,源码拓展基础Button功能,源码包括圆角、源码描边、源码交易猫 源码icon设置及按压水波纹等,源码满足日常需求。源码
背景处理:
1.2版本后,源码MaterialButton可自定义背景色,源码通过app:backgroundTint属性设置,源码背景为纯色时适用。源码渐变色背景需自定义drawable,源码hadoop 源码下载工使用android:background属性。源码
注意:若使用android:background设置背景,源码需将backgroundTint设为@empty,否则背景不生效。
阴影调整:
默认带阴影,可通过指定style为Widget.MaterialComponents.Button.UnelevatedButton去掉阴影,java工具类源码实现扁平化视图。
关于theme:
MDC1.1.0后,使用MaterialButton可能遇到闪退问题,需设置theme为MaterialComponents。
解决方法:
1. AndroidManifest配置全局theme
2. activity层面配置特定theme
3. 控件局部配置theme

设计思路
1、进行问题分析与设计,计划实现的功能为,开局选择人机或双人对战,确定之后比赛开始。
2、比赛结束后初始化棋盘,询问是否继续比赛或退出,后续可加入复盘、悔棋等功能。
3、整个过程中,涉及到了棋子和棋盘两种对象,同时要加上人机对弈时的AI对象,即涉及到三个对象。
