我想用5px在图像的拐角处用毕加索在imageview上显示。我创建了一个简单的类ImageRoundCorners
,在这个类中,我使用simple方法来圆化图像的角点,但是我的代码不起作用,角点也不圆。下面是我的代码:
file = new File(APP.DIR_APP + APP.IMAGE + "/ok.jpg");
if (file.isFile() && file.exists()) {
Uri uri = Uri.fromFile(file);
Picasso.with(this).load(uri).transform(new ImageRoundCorners()).into(fiv_image_view);
}
以及
ImageRoundCorners
类:import com.squareup.picasso.Transformation;
public class ImageRoundCorners implements Transformation {
@Override
public Bitmap transform(Bitmap source) {
Bitmap output = Bitmap.createBitmap(source.getWidth(), source
.getHeight(), Config.ARGB_8888);
Canvas canvas = new Canvas(output);
final int color = 0xff424242;
final Paint paint = new Paint();
final Rect rect = new Rect(0, 0, source.getWidth(), source.getHeight());
final RectF rectF = new RectF(rect);
final float roundPx = 50;
paint.setAntiAlias(true);
canvas.drawARGB(0, 0, 0, 0);
paint.setColor(color);
canvas.drawRoundRect(rectF, roundPx, roundPx, paint);
paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
canvas.drawBitmap(source, rect, rect, paint);
return output;
}
@Override
public String key() {
return "RoundImage";
}
}
这段代码中有什么问题,我如何解决?
我得到这个错误:
java.lang.IllegalStateException: Transformation RoundImage mutated input Bitmap but failed to recycle the original.
最佳答案
错误信息非常清楚。你只是忘记回收原始位图。
....
canvas.drawBitmap(source, rect, rect, paint);
source.recycle();
return output;
你的代码只缺一行!(我很惊讶所有这些答案告诉你做各种无关的,连根拔起的解决方案。)
