你可以在你的onCreate方法中添加这个

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

初始化你的时间值在毫秒，因为你想…

private  static int time=5000;

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........

简单的代码，它的工作:)简单的飞溅

int secondsDelayed = 1;
    new Handler().postDelayed(new Runnable() {
        public void run() {
            startActivity(new Intent(LoginSuccessFull.this, LoginActivity.class));
            finish();
        }
    }, secondsDelayed * 1500);

一个超级灵活的启动屏幕如何，可以使用相同的代码，并在AndroidManifest.xml中定义，因此代码永远不需要更改。我通常开发代码库，不喜欢定制代码，因为它很草率。

<activity
        android:name=".SplashActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
        <meta-data android:name="launch_class" android:value="com.mypackage.MyFirstActivity" />
        <meta-data android:name="duration" android:value="5000" />
</activity>

然后SpashActivity本身查找“launch_class”的元数据，然后创建Intent本身。元数据“持续时间”定义了启动画面持续的时间。

public class SplashActivity extends Activity {

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle icicle) {
    super.onCreate(icicle);
    setContentView(R.layout.activity_splash);

    ComponentName componentName = new ComponentName(this, this.getClass());

    try {
        Bundle bundle = null;
        bundle = getPackageManager().getActivityInfo(componentName, PackageManager.GET_META_DATA).metaData;
        String launch_class = bundle.getString("launch_class");
        //default of 2 seconds, otherwise defined in manifest
        int duration = bundle.getInt("duration", 2000);

        if(launch_class != null) {
            try {
                final Class<?> c = Class.forName(launch_class);

                new Handler().postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        Intent intent = new Intent(SplashActivity.this, c);
                        startActivity(intent);
                        finish();
                    }
                }, duration);

            } catch (ClassNotFoundException e) {
                e.printStackTrace();
            }
        }
    } catch (PackageManager.NameNotFoundException e) {
        e.printStackTrace();
    }
  }
}

以上所有的答案都非常好。但是存在内存泄漏的问题。 这个问题在Android社区通常被称为“泄露活动”。这到底是什么意思呢?

当配置发生变化时，比如方向变化，Android会销毁Activity并重新创建它。通常，垃圾收集器只会清除旧Activity实例的已分配内存，一切正常。

“泄漏一个活动”指的是垃圾收集器无法清除旧活动实例的已分配内存的情况，因为它被(强)引用于一个活动实例外的对象。每个Android应用程序都分配了特定数量的内存。当垃圾回收器不能释放未使用的内存时，应用程序的性能将逐渐下降，最终崩溃并出现OutOfMemory错误。

如何确定应用程序是否泄漏内存?最快的方法是在Android Studio中打开内存选项卡，并在改变方向时注意分配的内存。 如果分配的内存一直在增加而不减少，那么就有内存泄漏。

1.当用户改变方向时内存泄漏。

首先，你需要在布局资源splashscreen.xml文件中定义启动画面

启动画面活动的示例代码。

public class Splash extends Activity {
 // 1. Create a static nested class that extends Runnable to start the main Activity
    private static class StartMainActivityRunnable implements Runnable {
        // 2. Make sure we keep the source Activity as a WeakReference (more on that later)
        private WeakReference mActivity;

        private StartMainActivityRunnable(Activity activity) {
         mActivity = new WeakReference(activity);
        }

        @Override
        public void run() {
         // 3. Check that the reference is valid and execute the code
            if (mActivity.get() != null) {
             Activity activity = mActivity.get();
             Intent mainIntent = new Intent(activity, MainActivity.class);
             activity.startActivity(mainIntent);
             activity.finish();
            }
        }
    }

    /** Duration of wait **/
    private final int SPLASH_DISPLAY_LENGTH = 1000;

    // 4. Declare the Handler as a member variable
    private Handler mHandler = new Handler();

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

        // 5. Pass a new instance of StartMainActivityRunnable with reference to 'this'.
        mHandler.postDelayed(new StartMainActivityRunnable(this), SPLASH_DISPLAY_LENGTH);
    }

    // 6. Override onDestroy()
    @Override
    public void onDestroy() {
     // 7. Remove any delayed Runnable(s) and prevent them from executing.
     mHandler.removeCallbacksAndMessages(null);

     // 8. Eagerly clear mHandler allocated memory
     mHandler = null;
    }
}

在Android Marshmallow之后，我想到的另一个有效使用启动画面的方法是在应用的启动画面中请求必要的Android权限。

似乎大多数应用程序都是这样处理权限请求的。

对话框是糟糕的ui，它们破坏了主要流程，让你决定运行时间，事实上，大多数用户甚至可能不在乎你的应用程序是否想在SD卡上写东西。他们中的一些人甚至不明白我们试图传达什么，直到我们用简单的英语翻译出来。 一次请求权限可以减少每次操作前的“if else”次数，使代码看起来不那么杂乱。

这是一个例子，你可以在你的splash活动中请求运行Android OS 23+的设备的权限。

如果所有权限都被授予或已经授予或应用程序正在Pre Marshmallow上运行，那么只需去显示主要内容，几乎半秒的延迟，以便用户可以欣赏我们在阅读这个问题时所付出的努力，并试图给予我们最好的。
