将uri传递到另一个活动并将其转换为图像 [英] pass uri to another activity and convert it to image

问题描述

如何将图像的 uri 路径发送到另一个活动并将其转换为图像.我尝试了以下

How to send a uri path of an image to another activity and convert it to image. I tried the below

  protected void onActivityResult(int requestCode, int resultCode, Intent data) {

             super.onActivityResult(requestCode, resultCode, data);

              if (requestCode == 1 && resultCode == RESULT_OK && data != null && data.getData() != null) {

                  //file name
                     Uri selectedImage = data.getData();

                     Intent i = new Intent(this,
                              AddImage.class);
                    i.putExtra("imagePath", selectedImage);
                    startActivity(i);

像这样得到它

 String imagePath = getIntent().getStringExtra("imagePath");
            imageview.setImageURI(Uri.parse(imagePath ));

推荐答案

将您 URI 转换为String，同时添加到如下所示的 Intent 中

Convert you URI to String while adding to Intent like given below

i.putExtra("imagePath", selectedImage.toString());

，然后在您的 NextActivity 中获取 String ，然后像->

and in your NextActivity get the String and convert back to URI like ->

Intent intent = getIntent(); 
String image_path= intent.getStringExtra("imagePath"); 
Uri fileUri = Uri.parse(image_path) 
imageview.setImageURI(fileUri)
