yes路径必须是这样的格式

file:///mnt/sdcard/filename.jpg

(芬兰湾的科特林) 所以，截至2020年4月7日，上述选项都没用，但以下是对我有效的:

如果你想在val中存储位图，并设置一个imageView，使用这个: val bitmap = BitmapFactory.decodeFile(currentPhotoPath).also {bitmap -> imageView.setImageBitmap(bitmap)} 如果你只是想设置位图为和imageView，使用这个: BitmapFactory.decodeFile(currentPhotoPath).also {bitmap -> imageView.setImageBitmap(bitmap)}

使用startActivityForResult方法，如下所示

        startActivityForResult(new Intent(Intent.ACTION_PICK).setType("image/*"), PICK_IMAGE);

你可以得到这样的结果:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (resultCode != RESULT_OK) {
        return;
    }
    switch (requestCode) {
        case PICK_IMAGE:
            Uri imageUri = data.getData();
            try {
                Bitmap bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), imageUri);
            } catch (IOException e) {
                e.printStackTrace();
            }
         break;
    }
}
