CollageView is a library for creating simple photo collages in your applications. Would be great, for example, in profile page or feed page.

What's new in version 0.2.0?

• Updated project libraries, updated build.gradle, removed sample images

How to use?

Step 1. Add the JitPack repository to your build file

Gradle:

For gradle version 6.8 and above:

• settings.gradle, project level:

dependencyResolutionManagement {
    repositories {
        maven { url "https://jitpack.io" }
    }
}

• build.gradle, project level:

allprojects {
  repositories {
    maven { url "https://jitpack.io" }
  }
}

Maven:

<repositories>
  <repository>
    <id>jitpack.io</id>
    <url>https://jitpack.io</url>
  </repository>
</repositories>

Step 2. Add the dependency

Gradle:

• build.gradle, module level:

dependencies {
  implementation 'com.github.lopei:collageview:0.2.0'
}

Maven:

<dependency>
  <groupId>com.github.lopei</groupId>
  <artifactId>collageview</artifactId>
  <version>0.2.0</version>
</dependency>
  

Step 3. Add Collage view to your layout resource file:

<com.lopei.collageview.CollageView
  android:id="@+id/collageView"
  android:layout_width="match_parent"
  android:layout_height="match_parent" />

Step 4. Setup needed parameters and load photos:

CollageView collageView = (CollageView) findViewById(R.id.collageView);

  collageView
    .photoMargin(1)
    .photoPadding(3)
    .backgroundColor(Color.RED)
    .photoFrameColor(Color.BLUE)
    .useFirstAsHeader(true) // makes first photo fit device widtdh and use full line
    .defaultPhotosForLine(5) // sets default photos number for line of photos (can be changed by program at runtime)
    .iconSelector(this, getResources().getDimensionPixelSize(R.dimen.icon_size)) (or use 0 as size to wrap content)
    .useCards(true) // adds cardview backgrounds to all photos
    .maxWidth(100) // will resize images if their side is bigger than 100
    .placeHolder(R.drawable.placeholder_photo) //adds placeholder resource
    .headerForm(CollageView.ImageForm.IMAGE_FORM_SQUARE) // sets form of image for header (if useFirstAsHeader == true)
    .photosForm(CollageView.ImageForm.IMAGE_FORM_HALF_HEIGHT) //sets form of image for other photos
    .loadPhotos(urls); // here you can use Array/List of photo urls or array of resource ids

Step 5. Setup On Photo Click Listener (if needed)

collageView.setOnPhotoClickListener(new CollageView.OnPhotoClickListener() {
  @Override
  public void onPhotoClick(int position) {
     // do random stuff here
   }
});

Step 6. Setup icons for your images (if needed, to be used with .iconSelector(IconSelector))

collageView.iconSelector(new CollageView.IconSelector() {
                    @Override
                    public int getIconResId(int pos) {
                        if (pos == 0 || pos  == 4) {
                            return R.mipmap.ic_launcher;
                        }
                        return 0;
                    }
                }
, getResources().getDimensionPixelSize(R.dimen.icon_size));
