Create an Activity SplashScreen.java public class SplashScreen extends Activity { protected boolean _active = true; protected int _splashTime = 3000; // time to display the splash screen in ms @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.splashscreen); Thread splashTread = new Thread() { @Override public void run() { try { int waited = 0; while (_active && (waited < _splashTime)) { sleep(100); if (_active) { waited += 100; } } } catch (Exception e) { } finally { startActivity(new Intent(SplashScreen.this, MainActivity.class)); finish(); } }; }; splashTread.start(); } } splashscreen.xml will be like this <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="600px" android:layout_height="1024px" android:background="#FF0000"> </RelativeLayout>

一种方法是通过创建FullScreenActivity/EmptyActivity(例如SplashScreenActivity)，并将其设置为打开应用程序时显示的第一个活动。在AndroidManifest.xml中添加以下内容到您的活动

 <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

然后，您可以设置一个处理程序，在几秒钟后取消此活动。

new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {
                Intent i= new Intent(SplashScreenActivity.this,MainActivity.class);
                startActivity(i); //start new activity 
                finish();
            }
        }, 3000); //time in milliseconds

其次，如果你不想创建一个单独的活动，你可以在MainActivity上膨胀一个布局，并将布局可见性设置为GONE，或者在几毫秒后在现有的启动画面布局上膨胀主布局。

另一种方法是使用CountDownTimer实现

@Override
public void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
     setContentView(R.layout.splashscreen);

 new CountDownTimer(5000, 1000) { //5 seconds
      public void onTick(long millisUntilFinished) {
          mTextField.setText("seconds remaining: " + millisUntilFinished / 1000);
      }

     public void onFinish() {
          startActivity(new Intent(SplashActivity.this, MainActivity.class));
          finish();
     }

  }.start();
}

Create an activity: Splash Create a layout XML file: splash.xml Put UI components in the splash.xml layout so it looks how you want your Splash.java may look like this: public class Splash extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.splash); int secondsDelayed = 1; new Handler().postDelayed(new Runnable() { public void run() { startActivity(new Intent(Splash.this, ActivityB.class)); finish(); } }, secondsDelayed * 1000); } } change ActivityB.class to whichever activity you want to start after the splash screen check your manifest file and it should look like

<活动 android: name = "。屏” android: label = " @string / app_name " > > < /活动 <活动 android: name = "。飞溅” android: label = " @string / title_activity_splash_screen " > <意图过滤器> <action android:name="android.intent.action. main " /> <category android:name="android.intent.category. launcher " /> < /意图过滤器> > < /活动

创建一个活动，让我们活动命名为“a”，然后创建一个名为mysscreen .xml的xml文件，在其中设置一个启动画面图像作为背景，然后使用倒计时计时器从一个活动导航到另一个活动。要知道如何使用倒计时定时器看到我的答案在这个问题的TimerTask在Android?

上面的答案很好，但我想补充一些其他的东西。我是Android的新手，我在开发过程中遇到了这些问题。希望这能帮助到像我这样的人。

The Splash screen is the entry point of my app, so add the following lines in AndroidManifest.xml. <activity android:name=".SplashActivity" android:theme="@android:style/Theme.DeviceDefault.Light.NoActionBar"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> The splash screen should only show once in the app life cycle, I use a boolean variable to record the state of the splash screen, and only show it on the first time. public class SplashActivity extends Activity { private static boolean splashLoaded = false; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); if (!splashLoaded) { setContentView(R.layout.activity_splash); int secondsDelayed = 1; new Handler().postDelayed(new Runnable() { public void run() { startActivity(new Intent(SplashActivity.this, MainActivity.class)); finish(); } }, secondsDelayed * 500); splashLoaded = true; } else { Intent goToMainActivity = new Intent(SplashActivity.this, MainActivity.class); goToMainActivity.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT); startActivity(goToMainActivity); finish(); } } }

编码快乐!
