Android集成Glide样例(回调,圆角roundCorner,居中裁剪centerCrop,gif)

最近一次更新: 2019.08.08

背景

Glide是当前非常流程的图片加载框架，功能强大而且非常稳定。

集成指导 最简集成方式

1.dependencies中增加依赖

implementation 'com.github.bumptech.glide:glide:4.8.0'
annotationProcessor 'com.github.bumptech.glide:compiler:4.8.0'

2. Manifest文件中增加权限

3. 使用

• 样例1：

String url = "https://p3a.pstatp.com/weili/l/79054173089494582.jpg";
Context context = this;
Glide.with(context)
       .load(url)
       .into(imageView);

• 样例2（带回调，使用样例：加载完图片再显示出图片控件）：

String url = "https://p3a.pstatp.com/weili/l/79054173089494582.jpg";
Context context = this;
Glide.with(context)
       .load(url)
       .listener(new RequestListener() {
           @Override
           public boolean onLoadFailed(@Nullable GlideException e, Object model, Target target, boolean isFirstResource) {
               Toast.makeText(context, "加载失败!", Toast.LENGTH_SHORT).show();
               return false;
           }

           @Override
           public boolean onResourceReady(Drawable resource, Object model, Target target, DataSource dataSource, boolean isFirstResource) {
               Toast.makeText(context, "加载成功.", Toast.LENGTH_SHORT).show();
               return false;
           }
       })
       .into(imageView);

• 样例3:显示圆角及居中裁剪

//居中裁剪
private fun centerCropImg() {
    Glide.with(this)
            .load(url)
            .centerCrop()
            .into(roundCornerIv)
}

//圆角
private fun roundCornerImg() {
    Glide.with(this)
            .load(url)
            .transform(RoundedCorners(20))
            .into(centerCropIv)
}

//居中裁剪+圆角
private fun centerCropAndRoundCornerImg() {
    Glide.with(this)
            .load(url)
            .transform(MultiTransformation(CenterCrop(), RoundedCorners(20)))
            .into(roundCornerAndCenterCropIv)
}

效果图:

• 样例4:gif动图

val url = "https://c-ssl.duitang.com/uploads/item/201703/17/20170317135641_dFL5w.gif"
Glide.with(this)
        .load(url)
        .into(imageView)
