In the below code I have created splash screen. Here first I have added images in drawable folder, and then added in activity_splash_screen, In SplashScreenActivity I have also used Timer function. See the below code it will clerly describe you how to make spalsh screen.

Step(1)-SplashScreenActivity -

public class SplashScreenActivity extends Activity {
    private static final int SPLASH_TIME_OUT = 1000;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.activity_splash_screen);

        Timer timer = new Timer();
        timer.schedule(new TimerTask() {

            public void run() {
                SharedPreferenceManager preferenceManager = SharedPreferenceManager.getInstance();

                if (preferenceManager.getUserToken(SplashScreenActivity.this)==null ) {
                    Intent intent = new Intent(SplashScreenActivity.this, LoginActivity.class);
                    preferenceManager.setLoginCheck(SplashScreenActivity.this, true);
                    startActivity(intent);
                    finish();
                } else {
                    Intent intent = new Intent(SplashScreenActivity.this, HomeScreenActivity.class);
                    startActivity(intent);
                    finish();
                }
            }
        }, SPLASH_TIME_OUT);
    }
}

Step(2)-activity_splash_screen -

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".SplashScreen"
    android:background="@color/white"
    android:orientation="vertical">

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical">

            <ImageView
                android:id="@+id/ivLoginHeader"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:adjustViewBounds="true"
                android:scaleType="fitXY"
                android:src="@drawable/top1" />

            <ImageView
                android:id="@+id/ivLoginLogo"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_marginTop="@dimen/ivloginlogo_top_margin"
                android:src="@drawable/logo"/>

        </LinearLayout>

</LinearLayout>
