GlideImageDemo项目名
在要加载头像的地方声明
private
RequestManager
glideRequest
;
vh.
imgView
= contentView
.findViewById(R.id.
imgFansCircular
)
;
glideRequest
= Glide.
with
(
context
)
;
glideRequest
.load(Constant.
URL_BASE
+ head).transform(
new
GlideRoundTransform(
context
,
10
)).into(vh.
imgView
)
;
新建两个类
public class
GlideCircleTransform
extends
BitmapTransformation {
public
GlideCircleTransform
(Context context) {
super
(context)
;
}
@Override
protected
Bitmap
transform
(BitmapPool pool
,
Bitmap toTransform
, int
outWidth
, int
outHeight) {
return
circleCrop
(pool
,
toTransform)
;
}
private static
Bitmap
circleCrop
(BitmapPool pool
,
Bitmap source) {
if
(source ==
null
)
return null;
int
size = Math.
min
(source.getWidth()
,
source.getHeight())
;
int
x = (source.getWidth() - size) /
2
;
int
y = (source.getHeight() - size) /
2
;
//
TODO this could be acquired from the pool too
Bitmap squared = Bitmap.
createBitmap
(source
,
x
,
y
,
size
,
size)
;
Bitmap result = pool.get(size
,
size
,
Bitmap.Config.
ARGB_8888
)
;
if
(result ==
null
) {
result = Bitmap.
createBitmap

,
size

Bitmap.Config.
ARGB_8888
)
;
}
Canvas canvas =
new

;
Paint paint =
new

;
paint.setShader(
new

CLAMP
,

))
;
paint.setAntiAlias(
true
)
;
float

2f
;
canvas.drawCircle(r

,
r
,
paint)
;
return
result
;
}
@Override
public
String
getId
() {
return
getClass().getName()
;
}
}
另一个
public class

extends

private static float
radius
=
0f
;
public

(Context context) {
this
(context
,
4
)
;
}
public

(Context context
, int

super

;
this
.
radius
= Resources.
getSystem
().getDisplayMetrics().
density
* dp
;
}
@Override
protected

transform
(BitmapPool pool

, int

, int

return

;
}
private static

if

createBitmap

}
Canvas canvas =
new

Paint paint =
new

;
paint.setShader(
new

,

))
;
paint.setAntiAlias(
true
)
;
RectF rectF =
new
RectF(
0f
,
0f
,
source.getWidth()
,
source.getHeight())
;
canvas.drawRoundRect(rectF
,
radius
,
radius
,
paint)
;
return
result
;
}
@Override
public
String
getId
() {
return
getClass().getName() + Math.
round
(
radius
)
;
}
}
最后：在dependencies里添加
compile 'com.github.bumptech.glide:glide:3.6.1'
