CombineBitmap

效果预览

功能

  • 生成类似钉钉、微信 群聊组合头像Bitmap
  • 可使用图片资源id、bitmap或者使用url从网络加载,传入对应数组即可
  • 网络加载时支持线程池
  • 支持磁盘缓存、内存缓存。(记得申请磁盘缓存需要的文件存储权限
  • 对图片资源进行采样率压缩
  • 支持子图像的点击事件
  • ......

基本用法

Step 1. 添加JitPack仓库 在项目根目录下的 build.gradle 中添加仓库:

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

Step 2. 添加项目依赖

dependencies {
    implementation 'com.github.Othershe:CombineBitmap:1.0.5'
}

Step 3. 配置

CombineBitmap.init(context)
    .setLayoutManager() // 必选, 设置图片的组合形式,支持WechatLayoutManager、DingLayoutManager
    .setSize() // 必选,组合后Bitmap的尺寸,单位dp
    .setGap() // 单个图片之间的距离,单位dp,默认0dp
    .setGapColor() // 单个图片间距的颜色,默认白色
    .setPlaceholder() // 单个图片加载失败的默认显示图片
    .setUrls() // 要加载的图片url数组
    .setBitmaps() // 要加载的图片bitmap数组
    .setResourceIds() // 要加载的图片资源id数组
    .setImageView() // 直接设置要显示图片的ImageView
    // 设置“子图片”的点击事件,需使用setImageView(),index和图片资源数组的索引对应
    .setOnSubItemClickListener(new OnSubItemClickListener() {
        @Override
        public void onSubItemClick(int index) {

        }
    })
    // 加载进度的回调函数,如果不使用setImageView()方法,可在onComplete()完成最终图片的显示
    .setProgressListener(new ProgressListener() {
        @Override
        public void onStart() {

        }

        @Override
        public void onComplete(Bitmap bitmap) {

        }
    })
    .build();

由于生成的组合Bitmap是矩形的,要实现钉钉的圆形显示效果,这里用到了一个可圆形显示的ImageView控件:NiceImageView
