先看效果 1.新建一个Class类AudioView并继承View package topteam.com.activity_demo.diyview; import android.content.Context; import android.graphics.Canvas; import android.graphics.Color; import android.graphics.LinearGradient; import android.graphics.Paint; import andr

1.在res/values下面新建一个xml文件attrs.xml，里面放的是自定义View的各种属性 <?xml version="1.0" encoding="utf-8"?> <resources> <declare-styleable name="ToBarView"> <!-- 左边按钮 --> <attr name="leftBtnText" format="string"/> .
