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

启动画面不应该从布局文件加载，加载时可能仍然有一些延迟。

最好的方法是为你的SplashScreenActivity创建一个主题，并设置android:windowBackground为一个可绘制的资源。

https://www.bignerdranch.com/blog/splash-screens-the-right-way/

简而言之:

在manifest中声明你的SplashScreenActivity:

<activity
        android:name=".activities.SplashScreenActivity"
        android:theme="@style/SplashTheme"
        android:screenOrientation="portrait">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

在SplashScreenActivity.java中:

@Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    Intent intent = new Intent(this, MainActivity_.class);
    startActivity(intent);
    finish();

}

接下来创建主题背景窗口的资源:

<style name="SplashTheme" parent="Theme.Bumpfie.Base">
    <item name="android:windowBackground">@drawable/splash</item>
</style>

可绘制文件splash.xml:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@android:color/white"/>
    <item>
        <bitmap
            android:gravity="center"
            android:src="@drawable/app_logo"/>
    </item>
</layer-list>

非常简单的方法:

首先使用以下网站创建你的splash: https://www.norio.be/android-feature-graphic-generator/ 选择你的标志和口号，选择你美丽的背景。将其大小调整为4096x4096。 现在下载图片并上传至: https://apetools.webprofusion.com/app/#/tools/imagegorilla 生成所有需要的启动画面，所有设备，所有平台。

享受吧!

这里有足够的答案，将有助于实施。这篇文章旨在帮助其他人完成创建启动画面的第一步!

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。

}

     - Add in SplashActivity 

   public class SplashActivity extends Activity {

       private ProgressBar progressBar;
       int i=0;
       Context context;
       private GoogleApiClient googleApiClient;

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

           new Handler().postDelayed(new Runnable() {
               @Override
               public void run() {
                   startActivity(new Intent(Splash.this, LoginActivity.class));
                   finish();
               }
           }, 2000);

       }

   }

  - Add in activity_splash.xml

   <RelativeLayout
   xmlns:android="http://schemas.android.com/apk/res/android"
       xmlns:tools="http://schemas.android.com/tools"
       xmlns:custom="http://schemas.android.com/apk/res-auto"
       android:background="@color/colorAccent"
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       tools:context=".Splash">

       <ImageView
           android:id="@+id/ivLogo"
           android:layout_width="match_parent"
           android:layout_height="match_parent"
           android:src="@mipmap/icon_splash"
           android:layout_centerHorizontal="true"
           android:layout_centerVertical="true"/>


       <ProgressBar
           android:id="@+id/circle_progress"
           style="?android:attr/progressBarStyleHorizontal"
           android:layout_width="fill_parent"
           android:layout_height="wrap_content"
           android:layout_alignParentBottom="true"
           android:layout_marginBottom="5dp"
           android:max="100"
           android:progressTint="@color/green"
           android:visibility="visible" />

   </RelativeLayout>

  - Add in AndroidManifest.xml

    <activity android:name="ex.com.SplashActivity">
               <intent-filter>
                   <action android:name="android.intent.action.MAIN" />

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

在我的例子中，我不想创建一个新的活动只是为了显示2秒的图像。当启动我的MainActivity，图像被加载到持有者使用毕加索，我知道这需要大约1秒的加载，所以我决定做以下在我的MainActivity OnCreate:

splashImage = (ImageView) findViewById(R.id.spllll);

    this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);

    int secondsDelayed = 1;
    new Handler().postDelayed(new Runnable() {
        public void run() {
            getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
            splashImage.setVisibility(View.GONE);

        }
    }, secondsDelayed * 2000);

当启动应用程序时，发生的第一件事是显示ImageView，并通过将窗口标志设置为全屏来删除状态栏。然后我使用Handler运行2秒，2秒后我清除全屏标志，并设置ImageView的可见性为GONE。简单，简单，有效。
