DiskLruImageCache

Simple file based image cache

Include

Just add the following line to your build.gradle dependencies

compile "it.sephiroth.android.library.disklruimagecache:DiskLruImageCache:1.0.0"

Usage

DiskLruImageCache cache = new DiskLruImageCache( context, "my-unique-name", Integer.MAX_VALUE );

Read an entry from the cache

DiskLruImageCache.BitmapEntry entry = cache.get( "image-1", Metadata.class );

Write an entry

Metadata metadata = new Metadata();
metadata.value = 1;
DiskLruImageCache.BitmapEntry<Metadata> entry;
entry = new DiskLruImageCache.BitmapEntry<Metadata>( bitmap, metadata );
boolean success = cache.put( "image-1", entry, Bitmap.CompressFormat.JPEG, 70 );

The Metadata must be an instance of Parcelable, in this example is:

static class Metadata implements Parcelable {

	int value;

	public static final Parcelable.Creator<Metadata> CREATOR = new Parcelable.Creator<Metadata>() {
		public Metadata createFromParcel ( Parcel source ) {
			final Metadata f = new Metadata();
			f.value = source.readInt();
			return f;
		}

		@Override
		public Metadata[] newArray ( final int i ) {
			return new Metadata[0];
		}
	};

	@Override
	public int describeContents () {
		return 0;
	}

	@Override
	public void writeToParcel ( final Parcel parcel, final int i ) {
		parcel.writeInt( value );
	}
}
