【问题描述】：

我不确定，是什么阻止了它的工作。我有代码设置导致 3 秒的时间延迟，但视图不工作，它保持黑色，然后在 3 秒后切换到下一个屏幕。我想，我正在做延时，并且在 android 中没有调用某些东西来显示布局......

public void onCreate(Bundle savedInstanceState)

    super.onCreate(savedInstanceState);     
    start = System.currentTimeMillis();
    setContentView(R.layout.team);


protected void onStart()

    super.onStart();        
    while(game)
    
        now = System.currentTimeMillis();
        if (now - start >= 5000)
        
            game = false;
            Intent about = new Intent(this, SplashScreen.class);
            startActivity(about);
        
    

【参考方案1】：

我相信您想实现一个延迟几秒钟的屏幕，然后启动您的主应用程序。就像主应用程序启动之前的启动画面一样吗？

那么这对你有帮助！

 /** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) 
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    /** set time to splash out */
    final int welcomeScreenDisplay = 4000;
    /** create a thread to show splash up to splash time */
    Thread welcomeThread = new Thread() 

    int wait = 0;

    @Override
    public void run() 
    try 
    super.run();
    /**
    * use while to get the splash time. Use sleep() to increase
    * the wait variable for every 100L.
    */
    while (wait < welcomeScreenDisplay) 
    sleep(100);
    wait += 100;
    
     catch (Exception e) 
    System.out.println("EXc=" + e);
     finally 
    /**
    * Called after splash times up. Do some action after splash
    * times up. Here we moved to another main activity class
    */
    startActivity(new Intent(CurrentActivity.this, NextActivity.class));
    finish();
    
    
    ;
    welcomeThread.start();

这是一个延迟 4 秒的屏幕。

【参考方案2】：

您应该使用 Timer 类来启动新活动。
