个人网站用wordpress吗,龙岩到永定,排名优化方案,百度快速seo由于clipRegion的一些问题#xff0c;导致他被废弃了#xff0c;但又有时候会用到#xff0c;所以写了一个工具类来替代它 代码如下
package com.example;import android.graphics.Canvas;
import android.graphics.Paint;
import android.graphics.Path;

package com.example;import android.graphics.Canvas;
import android.graphics.Paint;
import android.graphics.Path;
import android.graphics.Rect;
import android.graphics.RectF;
import android.graphics.Region;
import android.graphics.RegionIterator;public class Util {public static void clipRegion(Region region, Canvas canvas){Region combinedRegion new Region();Path companew Path();RegionIterator regionIteratornew RegionIterator(region);Rect sumnew Rect();Rect rectnew Rect();while(regionIterator.next(rect)){
// combinedRegion.op(rect, Region.Op.UNION);compa.addRect(rect.left,rect.top,rect.right,rect.bottom, Path.Direction.CCW);
// canvas.clipRect(rect);}canvas.clipPath(compa);}public static void drawRegion(Region region, Canvas canvas){Paint paintnew Paint();paint.setStyle(Paint.Style.STROKE);RegionIterator regionIteratornew RegionIterator(region);Rect rectnew Rect();while(regionIterator.next(rect)){canvas.drawRect(rect,paint);}}
}
代码解释其实就是通过把region转化为path然后调用clippath来完成的。 代码有两个函数clipRegion和drawRegion就和名字一样一个是切割一个是绘画把相应的参数传入进去就可以了
