关于自定义view的学习

1.在values ->attrs创建

<declare-styleable name="CircleView">
    <attr name="circleColor" format="color" />
</declare-styleable>

2.在view 中 引用

TypedArray typedArray = context.obtainStyledAttributes(attrs, R.styleable.CircleView);
circleColor = typedArray.getColor(R.styleable.CircleView_circleColor, Color.BLUE);
typedArray.recycle();

3.在布局中使用即可

app:circleColor="#F22222"
