Usage

Album's main function is: Album and Gallery, the following are described separately.

Album

Use Album.album(this).start() to call up the album.

Album.album(this)
    .requestCode(999) // Request code.
    .toolBarColor(toolbarColor) // Toolbar color.
    .statusBarColor(statusBarColor) // StatusBar color.
    .navigationBarColor(navigationBarColor) // NavigationBar color.
    .title("Album") // Title.
    
    .selectCount(9) // Choose up to a few pictures.
    .columnCount(2) // Number of albums.
    .camera(true) // Have a camera function.
    .checkedList(mImageList) // Has selected the picture, automatically select.
    .start();

Accept the result：

ArrayList<String> mImageList;

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if(requestCode == 999) {
        if (resultCode == RESULT_OK) { // Successfully.
            // Parse select result.
            mImageList = Album.parseResult(data);
        } else if (resultCode == RESULT_CANCELED) {
            // User canceled.
        }
    }
}

Gallery

Use the Album.gallery(this).start () to call up the gallery.

Album.gallery(this)
    .requestCode(999) // Request code.
    .toolBarColor(toolbarColor) // Toolbar color.
    .statusBarColor(statusBarColor) // StatusBar color.
    .navigationBarColor(navigationBarColor) // NavigationBar color.
    
    .checkedList(mImageList) // List of pictures to preview.
    .currentPosition(position) // First display position image of the list.
    .checkFunction(true) // Anti-election function.
    .start();

Note:

• Be sure to pass in the collection of pictures you want to preview, otherwise it will return immediately after the start.
• It is recommended to call the gallery preview to judge if(currentPosition < mImageList.size()), to ensure that the entry of the position in the list.

If you need to have an anti-selection function at the time of preview，override the onActivityResult () method, after receiving the anti-selected picture List result:

ArrayList<String> mImageList;

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if(requestCode == 666) {
        if (resultCode == RESULT_OK) { // Successfully.
            // Parse select result.
            mImageList = Album.parseResult(data);
        } else if (resultCode == RESULT_CANCELED) {
            // User canceled.
        }
    }
}

Advanced configuration

This is not something that must be set.

Your application if use the image loading frame: Glide, Picasso, ImageLoader, you can use them to customize the picture loading interface for the album.

Album has provided a default ImageLoader, E.g:

public class Application extends android.app.Application {
    @Override
    public void onCreate() {
        super.onCreate();

        Album.initialize(new AlbumConfig.Build()
                .setImageLoader(new LocalImageLoader()) // Use default loader.
                .build()
        );
    }
}

According to the test, the recommended priority is as follows:

1. LocalImageLoader
2. Glide
3. Picasso

Here are examples of Glide and Picasso.

Glide

public class GlideImageLoader implements AlbumImageLoader {
    @Override
    public void loadImage(ImageView imageView, String imagePath, int width, int height) {
        Glide.with(imageView.getContext())
            .load(new File(imagePath))
            .into(imageView);
    }
}

...

Album.initialize(new AlbumConfig.Build()
    .setImageLoader(new GlideImageLoader()) // Use glide loader.
    .build()

Picasso

public class PicassoImageLoader implements AlbumImageLoader {

    @Override
    public void loadImage(ImageView imageView, String imagePath, int width, int height) {
        Picasso.with(imageView.getContext())
            .load(new File(imagePath))
            .centerCrop()
            .resize(width, height)
            .into(imageView);
    }
}

...

Album.initialize(new AlbumConfig.Build()
    .setImageLoader(new PicassoImageLoader()) // Use picasso loader.
    .build()
