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!

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;

虽然有很好的答案，但我将展示谷歌推荐的方法:

1)首先为启动画面创建一个主题: 你有一个名为splashscreenTheme的主题，你的启动器主题将是:

<style name="splashscreenTheme">
  <item name="android:windowBackground">@drawable/launch_screen</item>
</style>

注意:

android:windowBackground已经设置了你的溅屏图像编号 需要在UI中再次这样做。

你也可以在这里使用颜色来代替绘图。

2)设置主题为splashscreenActivity的manifest

   <activity
            android:name=".activity.splashscreenActivity"
            android:screenOrientation="portrait"
            android:theme="@style/splashscreenTheme">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

3)确保你的launch_screen drawable不在drawable文件夹如果你的图像不小。

这将导致更快的启动屏幕启动和拯救你从黑屏

这也避免了额外的透支

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

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);

    }

}

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);
