文章标签 java 实现 ui 风格 安卓 拟态

本文主要是介绍安卓java新拟态风格UI实现，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

继承drawable方式实现

如果有问题请多多指教

新2.0源码已更新，文章后面下载

文章最后由我提到的硬件加速问题，如不进行动态更新画布可绘制后转bitmap或在bitmap上绘制即可。(注意bitmap宽高，阴影是超出原有view大小绘制的)

更新了2.0版本在文章最后
更多玩法

Flat
Concave
Convex
Pressed
整体
点击UI互交

}

创建方法:

DrawableSpan(宽,高)
–这里的宽高指初始化背景大小，后面可重新设置大小
DrawableSpan(图形样式Style,宽,高)
DrawableSpan(使用旧DrawableSpan参数,图形样式Style,阴影样式Model)
DrawableSpan(使用旧DrawableSpan参数,阴影样式Model)
DrawableSpan(使用旧DrawableSpan参数)

自定义方法void:

setContainerdeltaLength(X轴阴影范围,Y轴阴影范围)
setContainerdeltaLength(阴影范围)–也就是x和y一样
–可以通过它改变阴影范围实现UI动态互交

setStyle(DrawableSpan.Style)–背景样式
DrawableSpan.Style.RECTANGLE 矩形
DrawableSpan.Style.CIRCLE 圆形

setModel(DrawableSpan.Model)–阴影样式
DrawableSpan.Model.FLAT 中间平
DrawableSpan.Model.CONCAVE 中间凹
DrawableSpan.Model.CONVEX 中间凸
DrawableSpan.Model.PRESSED 合并 平和凹

setColor(Color)–背景色0x
setColor(Color,Color)–背景色，阴影色
–如白色不要直接0xffffffff这样阴影是显示不出来的
需要比0xffffffff暗一点即可，黑色同理

setRound(float[])–圆角(数组)
–设置1~8个角
–参数{10} 所有角都圆角10
–参数{10,0,10,0} 左上,右上,右下,左下
–参数{10,10,10,10,10,10,10,10}
参考path.addRoundRect

setDraw(DrawableSpan.Draw)
–设置画布回调，可在画布继续绘制

invalidate()–直接刷新画布
invalidate(宽,高)–更新画布宽高
上面那些set方法都不会主动更新画布
需要调用此方法更新
也可在id.setBackground(invalidate())

简单调用，简写方法

DrawableSpan.invalidateView(DrawableSpan,View)
第一个参数为创建好的DrawableSpan
第二参数为需要设置背景的view

需要注意:

—1.禁用硬件加速(必须)
—2.根布局设置ClipChildren=false(必须);

如本体设置禁用硬件加速会导致ClipChildren失效
所以把禁用硬件加速设置到它的父布局

注意:
如view重叠后阴影是不生效的
两个必须的条件要满足
如果需要叠加要在它的后面放个父布局(给它弄个爹)
这个父布局(爹)的宽高一定要大于阴影辐射范围

暂时以此为准
