我也遇到一样的问题,如果设置其他的渐变颜色,开始角度会从360度开始

我修改成这样,能解决问题

/**
* 设置进度颜色(通过着色器实现渐变色)
* @param colors
*/
public void setProgressColor(int... colors){
if(isMeasureCircle){
Shader shader = new SweepGradient(mCircleCenterX,mCircleCenterX,colors,null);
Matrix matrix = new Matrix();
matrix.setRotate(-90, mCircleCenterX,mCircleCenterX);
shader.setLocalMatrix(matrix);
setShader(shader);
}else{
mShaderColors = colors;
isShader = true;
}
}

setProgressColor(int... colors)只是一个传入多颜色的方式(内部实例化一个默认的着色器)来实现渐变;如果默认的着色器的渐变效果满足不了你的需求,你完全可以要自定义着色器(包括渐变色的角度区间)来实现你想要的渐变效果,直接使用setShader(Shader shader) 即可。
