Maven

<dependency>
   <groupId>com.cesards.android</groupId>
   <artifactId>CropImageView</artifactId>
   <version>1.0.2</version>
   <type>aar</type>
</dependency>

Step 2

Define in xml:

<com.codeforvictory.android.superimageview.SuperImageView
   xmlns:custom="http://schemas.android.com/apk/res-auto"
   android:id="@+id/imageView1"
   android:src="@drawable/photo1"
   custom:crop="value" />

where value can take values

topLeft|centerLeft|bottomLeft|topRight|centerRight|bottomRight|centerTop|centerBottom

Or in code:

final CropImageView cropImageView = new CropImageView(CropActivity.this);
final Resources res = getResources();
cropImageView.setImageDrawable(res.getDrawable(images[position]));
final CropImageView.CropType cropType = imageCrops[position];
cropImageView.setCropType(cropType);

Performance tests (using Hugo)

Center Crop Sample (ImageView)

V/TestForegroundImageView﹕ ⇢ setFrame(l=0, t=0, r=1080, b=1557)
V/TestForegroundImageView﹕ ⇠ setFrame [0ms] = true
V/TestForegroundImageView﹕ ⇢ setFrame(l=1080, t=0, r=2160, b=1557)
V/TestForegroundImageView﹕ ⇠ setFrame [0ms] = true
V/TestForegroundImageView﹕ ⇢ setFrame(l=0, t=0, r=1080, b=1557)
V/TestForegroundImageView﹕ ⇠ setFrame [0ms] = false
V/TestForegroundImageView﹕ ⇢ setFrame(l=1080, t=0, r=2160, b=1557)
V/TestForegroundImageView﹕ ⇠ setFrame [0ms] = false
V/TestForegroundImageView﹕ ⇢ setFrame(l=0, t=0, r=1080, b=1701)

V/TestForegroundImageView﹕ ⇢ setFrame(l=1080, t=0, r=2160, b=1701)

Custom Crop Sample (CropImageView)

V/TestForegroundCropImageView﹕ ⇢ setFrame(l=0, t=0, r=1080, b=1557)
V/TestForegroundCropImageView﹕ ⇠ setFrame [0ms] = true
V/TestForegroundCropImageView﹕ ⇢ setFrame(l=1080, t=0, r=2160, b=1557)
V/TestForegroundCropImageView﹕ ⇠ setFrame [0ms] = true
V/TestForegroundCropImageView﹕ ⇢ setFrame(l=0, t=0, r=1080, b=1557)
V/TestForegroundCropImageView﹕ ⇠ setFrame [0ms] = false
V/TestForegroundCropImageView﹕ ⇢ setFrame(l=1080, t=0, r=2160, b=1557)
V/TestForegroundCropImageView﹕ ⇠ setFrame [0ms] = false
V/TestForegroundCropImageView﹕ ⇢ setFrame(l=0, t=0, r=1080, b=1701)
V/TestForegroundCropImageView﹕ ⇠ setFrame [0ms] = true
V/TestForegroundCropImageView﹕ ⇢ setFrame(l=1080, t=0, r=2160, b=1701)
V/TestForegroundCropImageView﹕ ⇠ setFrame [0ms] = true

Results: code used does not cause overhead in the UI thread.
