我们的眼睛就是我们的监狱，我们的眼光所到之处就是我们监狱的围墙。——尼采
首先请求授权
然后我们这里引入依赖
implementation 'com.hujiang.restvolley:restvolley:1.0.1'
然后调用函数
String filename = url.substring(url.lastIndexOf("/")); String localPath = context.getExternalFilesDir(Environment.DIRECTORY_PICTURES) + filename; RestVolleyDownload.download(context, url, localPath, new RestVolleyDownload.OnDownloadListener() { @Override public void onDownloadStart(String url) { } @Override public void onDownloadSuccess(String url, File file, int httpCode, Headers headers) { ToastUtils.shortToast("保存成功,文件地址：" + localPath); } @Override public void onDownloadFailure(String url, Exception e, int httpCode, Headers headers) { ToastUtils.shortToast("保存失败"); } @Override public void onDownloadProgress(String url, int downloadBytes, int contentLength, File file, int httpCode, Headers headers) { } });
就能实现根据网络图片url下载图片到本地啦！
