1、控件有很多属性，如android:id、android:layout_width、android:layout_height等，但是这些属性都是系统自带的属性。使用attrs.xml文件，可以自己定义属性。用attrs.xml文件自己定义了属性。
2、xmlns:test="http://schemas.android.com/apk/res/org.jinkia.jk_rockerview.RockerView"
(其中org.jinkia.jk_rockerview.RockerView是包名)
xmlns:app="http://schemas.android.com/apk/res-auto"
3、首先从R.styleable.RockerView获得了TypedArray变量，
TypedArray typedArray = context.obtainStyledAttributes(attrs, R.styleable.RockerView);
// 可移动区域背景
Drawable areaBackground = typedArray.getDrawable(R.styleable.RockerView_areaBackground);
属性格式为“RockerView_areaBackground”
