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

在Kotlin中编写以下代码:-

 Handler().postDelayed({
            val mainIntent = Intent(this@SplashActivity, LoginActivity::class.java)
            startActivity(mainIntent)
            finish()
        }, 500)

希望这对你有所帮助，谢谢........

启动画面示例:

public class MainActivity extends Activity {
    private ImageView splashImageView;
    boolean splashloading = false;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        splashImageView = new ImageView(this);
        splashImageView.setScaleType(ScaleType.FIT_XY);
        splashImageView.setImageResource(R.drawable.ic_launcher);
        setContentView(splashImageView);
        splashloading = true;
        Handler h = new Handler();
        h.postDelayed(new Runnable() {
            public void run() {
                splashloading = false;
                setContentView(R.layout.activity_main);
            }

        }, 3000);

    }

}

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?

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。
