### Android Activity with ColorArt and FadingImageView
Source: https://context7.com/michaelevans/colorart/llms.txt
This example shows how to integrate ColorArt with FadingImageView in an Android Activity. It loads an image, extracts dominant colors using ColorArt, and applies these colors to the ImageView background, container background, and text elements for a themed detail view.
```java
import android.app.Activity;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.os.Bundle;
import android.view.View;
import android.widget.TextView;
import org.michaelevans.colorart.library.ColorArt;
import org.michaelevans.colorart.library.FadingImageView;
public class DetailsActivity extends Activity {
private FadingImageView mImageView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_details);
// Get image resource ID from intent
int imageResId = getIntent().getIntExtra("image_id", R.drawable.default_album);
// Load and analyze bitmap
Bitmap album = BitmapFactory.decodeResource(getResources(), imageResId);
ColorArt colorArt = new ColorArt(album);
// Setup fading image view
mImageView = findViewById(R.id.image);
mImageView.setImageBitmap(album);
mImageView.setBackgroundColor(
colorArt.getBackgroundColor(),
FadingImageView.FadeSide.LEFT
);
// Apply background color to container
View container = findViewById(R.id.container);
container.setBackgroundColor(colorArt.getBackgroundColor());
// Apply text colors for visual hierarchy
TextView primary = findViewById(R.id.primary);
primary.setText("Song Title");
primary.setTextColor(colorArt.getPrimaryColor());
TextView secondary = findViewById(R.id.secondary);
secondary.setText("Artist Name");
secondary.setTextColor(colorArt.getSecondaryColor());
TextView detail = findViewById(R.id.detail);
detail.setText("Album • 2024");
detail.setTextColor(colorArt.getDetailColor());
}
}
```

### HashBag Utility for Color Frequency Counting
Source: https://context7.com/michaelevans/colorart/llms.txt
This Java code demonstrates the usage of the internal HashBag utility for counting color frequencies in an image. It shows how to initialize the HashBag, add pixel colors, retrieve the count for a specific color, and iterate through the unique colors and their frequencies.
```java
import org.michaelevans.colorart.library.HashBag;
// Create color frequency counter
HashBag colorBag = new HashBag();
// Add colors from image pixels
for (int x = 0; x < width; x++) {
for (int y = 0; y < height; y++) {
int pixelColor = bitmap.getPixel(x, y);
colorBag.add(pixelColor);
}
}
// Get frequency count for specific color
int redCount = colorBag.getCount(Color.RED);
// Iterate through unique colors
Iterator colorIterator = colorBag.iterator();
while (colorIterator.hasNext()) {
Integer color = colorIterator.next();
int frequency = colorBag.getCount(color);
// Process color and its frequency
}
```

### Extract Color Palette from Bitmap using ColorArt
Source: https://context7.com/michaelevans/colorart/llms.txt
This Java code demonstrates how to initialize the ColorArt library with a Bitmap, extract key colors (background, primary, secondary, detail), and apply them to Android UI elements. It assumes the ColorArt library is included as a dependency.
```java
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import org.michaelevans.colorart.library.ColorArt;
// Load bitmap from resources
Bitmap albumArt = BitmapFactory.decodeResource(getResources(), R.drawable.album_cover);
// Analyze the image
ColorArt colorArt = new ColorArt(albumArt);
// Extract colors
int backgroundColor = colorArt.getBackgroundColor();
int primaryColor = colorArt.getPrimaryColor();
int secondaryColor = colorArt.getSecondaryColor();
int detailColor = colorArt.getDetailColor();
// Apply to UI elements
View container = findViewById(R.id.container);
container.setBackgroundColor(backgroundColor);
TextView titleText = findViewById(R.id.title);
titleText.setTextColor(primaryColor);
TextView artistText = findViewById(R.id.artist);
artistText.setTextColor(secondaryColor);

### Android RecyclerView Adapter for ColorArt Theming
Source: https://context7.com/michaelevans/colorart/llms.txt
Implements a RecyclerView adapter to dynamically theme list items using ColorArt. Each list item's colors (background, primary text, secondary text) are extracted from an associated image and applied using FadingImageView and TextViews. This enables adaptive theming for dynamic content.
```java
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import androidx.recyclerview.widget.RecyclerView;
import org.michaelevans.colorart.library.ColorArt;
import org.michaelevans.colorart.library.FadingImageView;
import java.util.List;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.widget.TextView;
public class AlbumAdapter extends RecyclerView.Adapter {
private List albums;
public AlbumAdapter(List albums) {
this.albums = albums;
}
@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext())
.inflate(R.layout.album_item, parent, false);
return new ViewHolder(view);
}
@Override
public void onBindViewHolder(ViewHolder holder, int position) {
Album album = albums.get(position);
// Load bitmap
Bitmap bitmap = BitmapFactory.decodeResource(
holder.itemView.getContext().getResources(),
album.getImageResourceId()
);
// Analyze colors
ColorArt colorArt = new ColorArt(bitmap);
// Apply to views
holder.fadingImage.setImageBitmap(bitmap);
holder.fadingImage.setBackgroundColor(
colorArt.getBackgroundColor(),
FadingImageView.FadeSide.LEFT
);
holder.container.setBackgroundColor(colorArt.getBackgroundColor());
holder.title.setText(album.getTitle());
holder.title.setTextColor(colorArt.getPrimaryColor());
holder.artist.setText(album.getArtist());
holder.artist.setTextColor(colorArt.getSecondaryColor());
}
@Override
public int getItemCount() {
return albums.size();
}
static class ViewHolder extends RecyclerView.ViewHolder {
View container;
FadingImageView fadingImage;
TextView title;
TextView artist;
ViewHolder(View itemView) {
super(itemView);
container = itemView;
fadingImage = itemView.findViewById(R.id.album_image);
title = itemView.findViewById(R.id.album_title);
artist = itemView.findViewById(R.id.album_artist);
}
}
}
