如何在Xamarin Android中一次从Gallery (tickbox)中选择多张图片？

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Intent intent = new Intent();
intent.SetType("image/*");
intent.PutExtra(Intent.ExtraAllowMultiple, true);
intent.SetAction(Intent.ActionGetContent);
StartActivityForResult(Intent.CreateChooser(intent, "Select Pictures"), 1);

protected override void OnActivityResult(int requestCode, Result resultCode, Intent data)
{
    base.OnActivityResult(requestCode, resultCode, data);

    if (requestCode == 1 && resultCode == Result.Ok && data != null)
    {
        ClipData clipData = data.ClipData;
        if (clipData != null)
        {
            for (int i = 0; i < clipData.ItemCount; i++)
            {
                ClipData.Item item = clipData.GetItemAt(i);
                Uri uri = item.Uri;
                // 处理选择的图片
            }
        }
        else
        {
            Uri uri = data.Data;
            // 处理选择的图片
        }
    }
}
