JarCastingDiskLruImageCache
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 );
}
}
