android - 使用改造 android 裁剪后图像未上传
问题描述
我指的是本教程进行裁剪-> https://www.android-examples.com/android-image-cropping-example-tutorial-pick-gallery-camera/
它在提交时将裁剪的图像放置在编辑配置文件活动中的 imageview 中,它显示成功更新成功.. 但在帐户活动中,它没有在 profilepic 上显示图像...
调试时它只显示这个->data:image/png;base64
而不是编码字符串(AVDBJSV3jq ..)
为什么 convertostring 为空,为什么它不在此数据后附加字符串:image/png;base64
我不知道为什么它是空的
需要帮助提前谢谢
以下是我的代码

解决方案
您已将位图放入新变量中。您必须将其放入全局变量中。
bitmap = bundle!!.getParcelable<Bitmap>("data") profile?.setImageBitmap(bitmap)
只需在您尝试将新位图图像设置到变量val
之前删除。bitmap
