1. XML 파일 생성

[res/layout/activity_splash.xml]

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/colorPrimary"
    android:gravity="center"
    android:orientation="vertical">

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:gravity="center"
        android:orientation="vertical">

        <ImageView
            android:layout_width="100dp"
            android:layout_height="100dp"
            android:padding="20dp"
            android:src="@drawable/icon_logo" />

        <LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="@drawable/bg_white"
            android:orientation="horizontal"
            android:padding="5dp">

            <TextView
                style="@style/LargeFont"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="Bucket"
                android:textColor="@color/colorPrimary"
                android:textStyle="bold" />

            <TextView
                style="@style/LargeFont"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text=" List"
                android:textColor="@color/colorPrimary" />
        </LinearLayout>
    </LinearLayout>

    <TextView
        style="@style/SmallFont"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:padding="10dp"
        android:text="Copyright © 2017 Junhong-Kim. All rights reserved."
        android:textColor="#ffffff" />
</LinearLayout>

2. Java 파일 생성

[java/SplashActivity]

public class SplashActivity extends AppCompatActivity {
    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_splash);

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

3. AndroidMainfest에 activity 추가 및 intent-filter 정의

[manifests/AndroidManifest.xml]

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

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