我希望橡皮擦能顺利擦除,但在我的活动中,默认情况下它会擦除触摸画线并擦除触摸线是不正确的。我的代码是我所做的。
public void Draw(){
count=1;
bmp = Bitmap.createBitmap(fullimage2.getWidth(), fullimage2.getHeight(), Config.ARGB_8888);
c = new Canvas(bmp);
fullimage2.draw(c);
if(mode==0){
pnt.setColor(Color.BLACK);
pnt.setStyle(Paint.Style.STROKE);
pnt.setStrokeJoin(Paint.Join.ROUND);
pnt.setStrokeCap(Paint.Cap.ROUND);
pnt.setStrokeWidth(8);
c.drawPath(path,pnt);
}
else{
pnt1.setXfermode(new PorterDuffXfermode(
PorterDuff.Mode.CLEAR));
pnt1.setStrokeWidth(25);
pnt1.setStrokeCap(Paint.Cap.ROUND);
pnt1.setColor(Color.TRANSPARENT);
pnt1.setAlpha(0);
c.drawPath(path1,pnt1);
pnt1.setStyle(Style.STROKE);
pnt1.setMaskFilter(null);
pnt1.setAntiAlias(true);
}
