英文:
Blurred bitmap on canvas
问题
我在主活动中有一个基于视图的元素,以及在可绘制文件夹中的[图像][1]。
public class MyView extends View {
private Bitmap mSprite;
public MyView(Context context, @Nullable AttributeSet attrs) {
super(context, attrs);
mSprite = BitmapFactory.decodeResource(getResources(), R.drawable.plank);
}
@Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
canvas.drawBitmap(mSprite, 0.f, 0.f, null);
}
}
图像已显示,但看起来模糊且过大([参考链接][2])。如何获取位图的实际大小并在画布上绘制它?

英文:
I have View-based element in main activity and an image in drawable folder
public class MyView extends View {
private Bitmap mSprite;
public MyView(Context context, @Nullable AttributeSet attrs) {
super(context, attrs);
mSprite = BitmapFactory.decodeResource(getResources(), R.drawable.plank);
}
@Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
canvas.drawBitmap(mSprite, 0.f, 0.f, null);
}
}
The image is displayed but looks blurry and too large (ref). How can I get the actual size of bitmap and draw in on canvas?

对于任何遇到上述问题的人:只需将您的图片放在“nodpi”文件夹中,它将与其实际大小匹配。
英文:
For anyone faced the above issue: just put your image in nodpi
folder and it will match its actual size.
