如何从位图获取 Uri 对象 [英] How to get a Uri object from Bitmap
问题描述
在某个点击事件中,我要求用户添加图像.所以我提供了两个选项:
On a certain tap event, I ask the user to add an image. So I provide two options:
- 从图库添加.
- 点击来自相机的新图像.
我的目标是保留与这些图像相关的uri"列表.
My aim is to keep a list of "uri"s related to those images.
如果用户选择图库,那么我会得到图像 uri(这很简单).但是如果他选择相机,那么在拍完一张照片后,我得到了那张照片的Bitmap对象.
If the user chooses gallery, then I get the image uri (which is quite simple). But if he chooses camera, then after taking a picture, I am getting the Bitmap object of that picture.
现在如何将该 Bitmap 对象转换为 uri,或者换句话说,如何获取该位图对象的相关 Uri 对象?
Now how do I convert that Bitmap object to uri, or in other words, how can I get the relative Uri object of that bitmap object?
谢谢.
推荐答案
我的项目有同样的问题,所以我按照简单的方法(点击此处) 从位图中获取 Uri.
I have same problem in my project, so i follow the simple method (click here) to get Uri from bitmap.
public Uri getImageUri(Context inContext, Bitmap inImage) {
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
String path = MediaStore.Images.Media.insertImage(inContext.getContentResolver(), inImage, "Title", null);
return Uri.parse(path);
}
