How to show a splash screen for 3 seconds on Android?

Question

I would like the splash image to begin and stay for 3 seconds, and then disappear and continue or be replaced with the rest of the layout in the main.xml.

This is my code:

Main.java

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.main);

    ImageView splash = (ImageView) this.findViewById(R.id.splash);

main.xml

<?xml version="1.0" encoding="utf-8"?>
<!-- margin=0px, padding=20px -->
<!--textview padding=10dp, textSize=16sp-->
<!--px=pixel, dp=density indepen sp=scale indepen fontsize preference -->
<RelativeLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent">

   <ImageView
    android:id="@+id/splash"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:src="@drawable/splash2"/> 

  <ImageView
    android:id="@+id/myImageView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/bg_main"/> 

  <ImageView
    android:id="@+id/myImageView0"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/bar_top"/> 

<!-- 
  <TextView android:id="@+id/textItem"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center_horizontal"
    android:paddingTop="10dp"
    android:paddingLeft="110dp"
    android:background="#00000000"
    android:textColor="#ffffffff"
    android:textSize="22sp" 
    android:text="Find Car"
    android:enabled="false"  
  >
-->

<TabHost android:id="@android:id/tabhost"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
<RelativeLayout
   android:orientation="vertical"
   android:layout_width="fill_parent"
   android:layout_height="fill_parent"
   android:padding="3dp">
   <FrameLayout
       android:id="@android:id/tabcontent"
       android:layout_width="fill_parent"
       android:layout_height="fill_parent"
       android:layout_weight="1" />
   <TabWidget
       android:id="@android:id/tabs"
       android:layout_width="fill_parent"
       android:layout_height="wrap_content"
       android:layout_alignBottom = "@android:id/tabcontent"
       />
    </RelativeLayout>
    </TabHost>
</RelativeLayout>

For Kotlin :

class SplashActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_splash)

        Handler().postDelayed(Runnable {
            val i = Intent(this@SplashActivity, HomeScreen::class.java)
            startActivity(i)
            finish()
        }, 3000)


    }
}

Use Handler to hold the UI for some time:

public class SplashActivity extends Activity {

    /*Duration of wait*/
    private final int SPLASH_DISPLAY_LENGTH = 2000;

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

        new Handler(Looper.getMainLooper()).postDelayed(new Runnable() {
            @Override
            public void run() {
                /* Create an Intent that will start the MainActivity. */
                Intent mainIntent = new Intent(SplashActivity.this, MainActivity.class);
                startActivity(mainIntent);
                finish();
            }
        }, SPLASH_DISPLAY_LENGTH);
    }
}
