首先需要声明private ActivityResultLauncher<String> imagePickerLauncher;
之后，这里是如何启动图像选择器

// Launch the image picker
        imagePickerLauncher.launch("image/*");

为了检索结果，您复制以下代码

// Initialize the imagePickerLauncher
        imagePickerLauncher = registerForActivityResult(new 
        ActivityResultContracts.GetContent(), uri -> {
            if (uri != null) {
                 // Do something with the selected image URI
                 // For example, add it to the RecyclerView adapter
                
             }
         });
