SetImageUri显示无图像

Question

I want to let a image on my phone to show up in the Imageview. But in the ANdroid Studio emulator it is working but not on my own phone.

String imgPath = getIntent().getExtras().getString("imgPath");
    System.out.println(imgPath);


    if(!imgPath.equals("?"))
    {
        File img_file = new File(imgPath);
        ImageView imgView = findViewById(R.id.show_image_war);
        imgView.setImageURI(Uri.fromFile(img_file));
    }

The path is /storage/emulated/0/imagesWarranty/img_MyWarranty_ID1.jpg . Both on the image in my phone and the path in my code where I get the image.

It might be issue of resolution. Even I was getting error of resolution while I was displaying image from uri.

I used below code and It worked for me :

Uri imageUri = Uri.parse(imagePath);
                        BitmapFactory.Options options = new BitmapFactory.Options();
                        options.inJustDecodeBounds = true;
                        BitmapFactory.decodeFile(new File(imageUri.getPath()).getAbsolutePath(), options);
                        int imageHeight = options.outHeight;
                        int imageWidth = options.outWidth;
                        if (imageHeight > 4096 || imageWidth > 4096) {
                            BitmapFactory.Options opts = new BitmapFactory.Options();
                            opts.inSampleSize = 4;
                            Bitmap bitmap = BitmapFactory.decodeFile(imageUri.toString(), opts);
                            viewHolder.imgAvatarLogoList3.setImageBitmap(bitmap);
                        } else {
                            Picasso.with(context)
                                    .load(new File(imageUri.getPath())) // Uri of the picture
                                    .into(viewHolder.imgAvatarLogoList3);
                        }

Addition to this answer [ https://stackoverflow.com/a/48354307/9255006] In that rotation bug define the image orientation for the image using ExifInterface.

Here is the code

private void SetOrientation(){

    try {
        ExifInterface exif=new ExifInterface(photoURI.getPath());
        int orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION,ExifInterface.ORIENTATION_UNDEFINED);

        if (orientation == ExifInterface.ORIENTATION_ROTATE_90) { orientationInDegrees=90; }
        else if (orientation == ExifInterface.ORIENTATION_ROTATE_180) { orientationInDegrees=180; }
        else if (orientation == ExifInterface.ORIENTATION_ROTATE_270) { orientationInDegrees=270; }
        else { orientationInDegrees=0; }

        Toast.makeText(this, String.valueOf(orientationInDegrees), Toast.LENGTH_SHORT).show();

    } catch (IOException e) {
        e.printStackTrace();
    }
}

You can then set this orientation to your image.
