android 调用相机

调用相机：

Intent intent = new Intent(MediaStore.ActionImageCapture);
StartActivityForResult(intent, 13);

protected override void OnActivityResult(int requestCode, [GeneratedEnum] Result resultCode, Intent data)
        {
            base.OnActivityResult(requestCode, resultCode, data);
            var bitmap = (Bitmap)data.Extras.Get("data");
        }

调用相册：

Intent intent = new Intent(Intent.ActionGetContent,null);
            intent.SetDataAndType(MediaStore.Images.Media.ExternalContentUri, "image/*");
            StartActivityForResult(intent, 14);

protected override void OnActivityResult(int requestCode, [GeneratedEnum] Result resultCode, Intent data)
        {
            base.OnActivityResult(requestCode, resultCode, data);
            var bmp = Android.Provider.MediaStore.Images.Media.GetBitmap(this.ContentResolver, data.Data);
        }
