CompatTextView

前言

在项目开发过程中在drawable目录下会逐渐被shape,selector等xml文件充斥,到项目后期会变得难以维护,还在一定程度上增加了安装包的大小,基于这个现象,CompatTextView借此而生

特点

CompatTextView继承自AppCompatTextView,目前支持了以下功能:

  • 支持shape的solid、stroke、gradient、radius的配置
  • 支持enabled、pressed、selected、unenabled共计4种状态的配置
  • 不再需要写大量的shape、selector文件配置
  • 支持上下左右的drawable大小配置,SVG支持、Tint着色支持
  • 支持上下左右的drawable的对齐方式配置

dependencies {
    compile 'com.tk.compattextview:library:1.1'
}

顾名思义,CompatTextView被用来扩展、兼容、简化一些开发作业,如果您需要一些炫酷的功能,可以看看以下基于TextView扩展的开源项目:
