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();
    }
  }
}

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();
    }

    ...
}

public class SplashActivity extends Activity {

  Context ctx;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      ctx = this;
      setContentView(R.layout.activity_splash);

      Thread thread = new Thread(){
          public void run(){
              try {
                  sleep(3000);
              } catch (InterruptedException e) {
                  e.printStackTrace();
              }

              Intent in = new Intent(ctx,MainActivity.class);
              startActivity(in);
              finish();
          }
      };
      thread.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?
