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);

    }

}

应用发布时间和主题发布屏幕(Android Performance Patterns Season 6 Ep. 4) Android中的启动画面:正确的方法

旧的回答:

如何:简单的启动画面

这个答案会告诉你如何在应用启动时固定时间显示启动画面。例如，你可以选择显示3秒的启动画面。然而，如果你想要在可变的时间内(例如应用启动时间)显示飞溅屏幕，你应该看看Abdullah的答案https://stackoverflow.com/a/15832037/401025。但是要注意，应用程序在新设备上的启动速度可能非常快，所以用户只会看到一个flash，这是糟糕的用户体验。

首先，您需要在layout.xml文件中定义飞溅屏幕

  <?xml version="1.0" encoding="utf-8"?>
  <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          android:orientation="vertical" android:layout_width="fill_parent"
          android:layout_height="fill_parent">

          <ImageView android:id="@+id/splashscreen" android:layout_width="wrap_content"
                  android:layout_height="fill_parent"
                  android:src="@drawable/splash"
                  android:layout_gravity="center"/>

          <TextView android:layout_width="fill_parent"
                    android:layout_height="wrap_content"
                    android:text="Hello World, splash"/>

  </LinearLayout>

你的活动:

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.os.Handler;

public class Splash extends Activity {

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

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

        /* New Handler to start the Menu-Activity 
         * and close this Splash-Screen after some seconds.*/
        new Handler().postDelayed(new Runnable(){
            @Override
            public void run() {
                /* Create an Intent that will start the Menu-Activity. */
                Intent mainIntent = new Intent(Splash.this,Menu.class);
                Splash.this.startActivity(mainIntent);
                Splash.this.finish();
            }
        }, SPLASH_DISPLAY_LENGTH);
    }
}

这就是全部;)

有时用户打开SplashActivity并立即退出，但应用程序仍然在SPLASH_SCREEN_DISPLAY_LENGTH后转到MainActivity。

为了防止它:在SplashActivity中，你应该在移动到MainActivity之前检查SplashActivity是否结束

public class SplashActivity extends Activity {

    private final int SPLASH_SCREEN_DISPLAY_LENGTH = 2000;

    @Override
    public void onCreate(Bundle icicle) {
        ...
        new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {

                if (!isFinishing()) {//isFinishing(): If the activity is finishing, returns true; else returns false.
                    startActivity(new Intent(SplashActivity.this, MainActivity.class));
                    finish();
                }

            }, SPLASH_SCREEN_DISPLAY_LENGTH);
        }                             
   }                                
}

希望这对你有所帮助

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>

在Android中，启动画面是一个有点不可用的对象:为了隐藏主活动启动的延迟，它不能尽快加载。使用它有两个原因:广告和网络运营。

实现为对话框使跳跃没有延迟从启动画面到主UI的活动。

public class SplashDialog extends Dialog {
    ImageView splashscreen;
    SplashLoader loader;
    int splashTime = 4000;

    public SplashDialog(Context context, int theme) {
        super(context, theme);
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_splash);
        setCancelable(false);

        new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {
                cancel();
            }
        }, splashTime);

    }
}

布局:

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@color/white">

    <ImageView
        android:id="@+id/splashscreen"
        android:layout_width="190dp"
        android:layout_height="190dp"
        android:background="@drawable/whistle"
        android:layout_centerInParent="true" />

</RelativeLayout>

并开始:

public class MyActivity extends ActionBarActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        if (getIntent().getCategories() != null &&  getIntent().getCategories().contains("android.intent.category.LAUNCHER")) {
            showSplashScreen();
        }
    }

    protected Dialog splashDialog;
    protected void showSplashScreen() {
        splashDialog = new SplashDialog(this, R.style.SplashScreen);
        splashDialog.show();
    }

    ...
}
