Displaying Images with the Glide Library

Overview

Glide is an Image Loader Library for Android developed by bumptech and is a library that is recommended by Google. It has been used in many Google open source projects including Google I/O 2014 official application.

Guide is incomplete and needs attention

Setup

Add to your app/build.gradle file:

repositories {
  mavenCentral() // jcenter() works as well because it pulls from Maven Central
}

dependencies {
  compile 'com.github.bumptech.glide:glide:3.7.0'
  compile 'com.android.support:support-v4:19.1.0'
}

Basic Usage

Glide.with(context)
    .load("http://pathtoimage.com/graphic.png")
    .into(ivImg);

Advanced Usage

Resizing images with:

Glide.with(context)
    .load("http://pathtoimage.com/graphic.png")
    .override(300, 200)
    .into(ivImg);

Placeholder and error images:

Glide.with(context)
    .load("http://pathtoimage.com/graphic.png")
    .placeholder(R.drawable.placeholder)
    .error(R.drawable.imagenotfound)
    .into(ivImg);

Cropping images with:

Glide.with(context)
    .load("http://pathtoimage.com/graphic.png")
    .centerCrop()
    .into(ivImg);

Transforming images with:

Glide.with(context)
    .load("http://pathtoimage.com/graphic.png")
    .transform(new CircleTransform(context))
    .into(ivImg);

Configuration

You can configure Glide by creating a GlideConfiguration.java file:

public class GlideConfiguration implements GlideModule {

    @Override
    public void applyOptions(Context context, GlideBuilder builder) {
        // Apply options to the builder here.
        // Glide default Bitmap Format is set to RGB_565 since it 
        // consumed just 50% memory footprint compared to ARGB_8888.
        // Increase memory usage for quality with:
        builder.setDecodeFormat(DecodeFormat.PREFER_ARGB_8888);
    }

    @Override
    public void registerComponents(Context context, Glide glide) {
        // register ModelLoaders here.
    }
}

And then define it as meta-data inside AndroidManifest.xml:
