Question

我需要在第5次活动之前从第1次活动转移到第2次活动，然后再转到第2次活动。我的第一个活动包含一个使用以下代码旋转的图像 -

ImageForRotation.StartAnimation(loadedImage)

第二个活动是登录页面。这是我的代码 -

base.OnCreate(bundle);
SetContentView(Resource.Layout.SplashScreen);
ImageView ImageForRotation = FindViewById < ImageView > (Resource.Id.imageForRotation);

var loadedImage = AnimationUtils.LoadAnimation(this, Resource.Animation.SplashScreenImageRotation);

ImageForRotation.StartAnimation(loadedImage);
//here the code for 5 second wait time which i don't know
StartActivity(typeof(LoginScreen)); //second activity

Answer 1

像这样，这是你的第一个活动

protected void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.activity_main);
       NextActivity();
}

public void NextActivity()
{   
    new Handler().postDelayed(new Runnable(){
        @Override
        public void run() {

            Intent mainIntent = new Intent(MainActivity.this,Main2Activity.class);
            MainActivity.this.startActivity(mainIntent);
            MainActivity.this.finish();
        }
    }, 5000);

}

Answer 2

//Wait a number of milliseconds. There are 1000 milliseconds in a second.    
System.Threading.Thread.Sleep(5000);

//Save time by using System.Threading;
using System.Threading;
Thread.Sleep(5000);

Answer 3

我不确定你为什么要等待5秒，但是如果你想在完成动画后启动 LoginScreen ，那么你可以通过 setAnimationListener 来实现这一点方法

以下是有关它的详细信息：

public void setAnimationListener(Animation.AnimationListener listener)

它将动画侦听器绑定到此动画。动画侦听器会通知动画事件，例如动画结束或动画重复。

参数：

侦听器 - 要通知的动画侦听器

Answer 4

SetContentView(Resource.Layout.SplashScreen);
   ImageView ImageForRotation = FindViewById<ImageView>(Resource.Id.imageForRotation);

    var loadedImage = AnimationUtils.LoadAnimation(this,Resource.Animation.SplashScreenImageRotation);


    ImageForRotation.StartAnimation(loadedImage);
    System.Threading.Thread.Sleep(5000);
    StartActivity(typeof(LoginScreen)); //second activity

Answer 5

创建处理程序以在特定时间间隔（例如5000毫秒）之后切换到下一个活动

new Handler().postDelayed(new Runnable() {

        /*
         * Showing your animation screen with a timer. This will be useful when you
         * want to show case your app logo / company
         */

        @Override
        public void run() {
            // This method will be executed once the timer is over
            // Start your app main activity
            Intent i = new Intent(CurrentScreen.this, NextActivity.class);
            startActivity(i);

            // close this activity
            finish();
        }
    }, 5000);

在添加处理程序之前编写动画代码。
