Rounded Coners With Glide
We start use Glide library, which is a fast and efficient open source media management and image loading framework for Android that wraps media decoding, memory and disk caching, and resource pooling into a simple and easy to use interface.
Now we will learn how to rounded corners with this library.
The first step if we use this library it is that we should to add in our dependencies:
compile 'com.github.bumptech.glide:glide:3.7.0'
Now we will learn how to rounded corners with this library.
The first step.

In your layout we create a ImageView, something like that:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | <? xml version = "1.0" encoding = "utf-8" ?> android:layout_width = "match_parent" android:layout_height = "match_parent" android:paddingBottom = "@dimen/activity_vertical_margin" android:paddingLeft = "@dimen/activity_horizontal_margin" android:paddingRight = "@dimen/activity_horizontal_margin" android:paddingTop = "@dimen/activity_vertical_margin" tools:context = "com.thedeveloperworldisyours.roundedconerswithglide.MainActivity" > < ImageView android:id = "@+id/activity_main_image_view" android:layout_width = "wrap_content" android:layout_height = "wrap_content" android:layout_centerInParent = "true" /> </ RelativeLayout > |
Now in your activity
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 | import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.widget.ImageView; import com.bumptech.glide.Glide; public class MainActivity extends AppCompatActivity { public static int sCorner = 15 ; public static int sMargin = 2 ; @Override protected void onCreate(Bundle savedInstanceState) { super .onCreate(savedInstanceState); setContentView(R.layout.activity_main); ImageView imageView = (ImageView) findViewById(R.id.activity_main_image_view); Glide.with( this ) .bitmapTransform( new RoundedCornersTransformation( MainActivity. this ,sCorner, sMargin)) .into(imageView); } } |
And your manifest add permission of internet, if you want to get image from internet
1 2 3 4 5 | < manifest xlmns:android...> ... < uses-permission android:name = "android.permission.INTERNET" /> < application ... </manifest> |
You can check my example in github
very amazing and useful
Thank You
Hey! You got the transformation code from here https://github.com/wasabeef/glide-transformations/blob/master/transformations/src/main/java/jp/wasabeef/glide/transformations/RoundedCornersTransformation.java .
Credit your sources.
very goooooooooooood.
