我为Android编写应用程序并希望制作动画启动画面
我像这样做了图像启动画面
Styles.xml:
<resources>
<style name="Theme.Splash" parent="android:Theme">
<item name="android:windowBackground">@drawable/splash</item>
<item name="android:windowNoTitle">true</item>
</style>
</resources>
和SplashActivity:
[Activity(Theme = "@style/Theme.Splash", MainLauncher = true, NoHistory = true)]
public class SplashActivity : Activity
{
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
Thread.Sleep(10000);
StartActivity(typeof(Activity1));
}
}
但我有4个像素,我想制作动画闪屏。我怎么能这样做?

使用动画列表 - 在您的drawable文件夹中创建xml,如下所示:
ImageView your_imageView = (ImageView) findViewById(R.id.rocket_image);
your_imageView.setBackgroundResource(R.drawable.your_animation_list);
AnimationDrawable your_animation = (AnimationDrawable) your_imageView.getBackground();
your_animation.start(); // Start the animation
然后像这样开始动画:
{{1}}

您可以使用FadeImageView类https://blog.xamarin.com/android-tricks-fadeimageview/从一个图像淡入淡出到另一个图像
包含FadeImageView作为教程,并使用以下内容设置动画:
using Android.Views.Animations;
AlphaAnimation fadeIn;
AlphaAnimation fadeOut;
fadeIn = new AlphaAnimation (0, 1) {Duration = 500};
fadeOut = new AlphaAnimation (1, 0) {Duration = 500};
然后设置动画结束时要发生的事情,如调用更改图像的方法
EventHandler<Animation.AnimationEndEventArgs> callback = (s, e) => {
StartAnimation (fadeOut);
ChangePic ();
};
fadeIn.AnimationEnd += callback;
fadeimageview.SetImageBitmap(bitmap);
fadeimageview.StartAnimation (fadeIn);
ChangePic简单:
private void ChangePic(){
if (bitmapList.Count >= 1)
{
fadeimageview.SetImageBitmap(bitmapList[bitmapList.Count - 1]);
bitmapList.RemoveAt[bitmapList.Count - 1];
fadeimageview.StartAnimation (fadeIn);
}
}
