根据你提供的代码，似乎你想使用 Base64 编码的图片数据来显示一个 ImageView。但是，我发现你在解码 Base64 字符串时移除了 "data:image/png;base64," 这个前缀，这可能是导致显示图片为空的原因之一。

另外，你获取的字节数组长度为 14096，但这个长度可能会因为编码方式而有所不同，所以建议使用 decodedString.length 来确定字节数组的长度。

git merge遇到冲突文件

当使用git merge命令进行分支合并时，如果遇到冲突文件，会在执行git commit命令后进入一个类似于vim的操作界面。在这个界面中，你需要删除与冲突相关的文件名称行，例如：Conflicts: RedisKeyEnum.java。然后，你需要输入提交信息。在提交信息中，以‘#’开头的行将会被忽略，而提交信息为空则会终止提交操作。完成这些步骤后，你可以执行git push命令将合并后的内容推送到远程仓库分支。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
