当我滑动图库时,根据滑动速度,多个图像从右向左移动.您可以告诉我如何将滑动限制为一次只有1张图片,无论我刷多快?
[Activity(Label = "App3", MainLauncher = true, Icon = "@drawable/icon")]
public class MainActivity : Activity
{
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
// Set our view from the "main" layout resource
SetContentView (Resource.Layout.Main);
Gallery gallery = (Gallery)FindViewById<Gallery>(Resource.Id.gallery);
gallery.Adapter = new ImageAdapter(this);
gallery.ItemClick += delegate (object sender, Android.Widget.AdapterView.ItemClickEventArgs args) {
Toast.MakeText(this, args.Position.ToString(), ToastLength.Short).Show();
};
}
}
最佳答案 尝试覆盖Gallery OnFling()方法,不要调用超类OnFling()方法.
通过这种方式滑动画廊推进一个项目到时间.
这将使画廊每次滑动前进一个项目.
编辑:
您可以创建一个ExtendedGallery类:
public class ExtendedGallery : Gallery
{
public ExtendedGallery(Context context) : base(context)
{
}
public override bool OnFling (MotionEvent e1, MotionEvent e2, float velocityX, float velocityY)
{
//return base.OnFling (e1, e2, velocityX, velocityY);
return false;
}
}
然后使用ExtendedGallery而不是Gallery.
