Android splash screen are normally used to show  some kind of progress before the application loads completely.That progress can be getting data from Sqlite database, data from internet or it can be any background process. We can use splash screen for just showing our Application logo

splashscreen.xml:

<RelativeLayout 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"

    android:paddingBottom="@dimen/activity_vertical_margin"

    android:paddingLeft="@dimen/activity_horizontal_margin"

    android:paddingRight="@dimen/activity_horizontal_margin"

    android:paddingTop="@dimen/activity_vertical_margin"

  // here background image should be kept under res/drawable folder

    android:background="@drawable/bishop"

    tools:context=".SplashscreenActivity" >

    <TextView

        android:id="@+id/splashtextview"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:layout_alignParentBottom="true"

        android:layout_alignParentLeft="true"

        android:layout_marginBottom="40dp"

        android:layout_marginLeft="16dp"

        android:text="Bishop Heber"

        android:textColor="#FFFAFA"

import android.os.Bundle;

import android.os.Handler;

import android.app.Activity;

import android.content.Intent;

import android.graphics.Typeface;

import android.view.Menu;

import android.widget.TextView;

public class SplashscreenActivity extends Activity {

//In AndroidMainfest.xml this file should be declared as launcher Activity

//Splashscreen timer is for showing splashscreen for particular time.

private static int SPLASH_TIME_OUT=3000;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_splashscreen);

TextView splashtxt = (TextView)findViewById(R.id.splashtextview);

//Getting ttf(True type font) font style.

//Before we have to copy ttf file in assets folder

Typeface type = Typeface.createFromAsset(getAssets(), "epohistory.ttf");

// setting style to textview

splashtxt.setTypeface(type);

  new Handler().postDelayed(new Runnable(){

     /* Inside this anonymous inner class we are creating a runnable thread and 

      * overriding run method. This anonymous inner class is subclass to Handler class                               */

@Override

public void run() {

/* Creating an Intent to start another activity

 * After starting MainpageActivity  i am closing this (SplashscreenActivity) 

        * Activity.

         */

Intent i = new Intent(SplashscreenActivity.this,MainpageActivity.class);

startActivity(i);

finish();

}

      },SPLASH_TIME_OUT);

   }

}

Main Page Activity:

package com.solomon.splashscreenexample;

import android.app.Activity;

import android.os.Bundle;

import android.view.Gravity;

import android.widget.LinearLayout;

import android.widget.ScrollView;

import android.widget.TextView;

public class MainpageActivity extends Activity{

// In AndroidMainfest.xml file we should declare this Activity

@Override

protected void onCreate(Bundle savedInstanceState) {

// TODO Auto-generated method stub

super.onCreate(savedInstanceState);

//Creating an linearlayout and setting its orientation as Vertical

LinearLayout ll = new LinearLayout(this);

ll.setOrientation(LinearLayout.VERTICAL);

//Creating an Textview 

TextView mainpagetxt = new TextView(this);

mainpagetxt.setText("Main page TextView");

mainpagetxt.setGravity(Gravity.CENTER);

//setting textview to Linearlayout

ll.addView(mainpagetxt);

this.setContentView(ll);

}

}

AndroidMainfest.xml:

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

    package="com.solomon.splashscreenexample"

    android:versionCode="1"

    android:versionName="1.0" >

    <uses-sdk

        android:minSdkVersion="8"

        android:targetSdkVersion="19" />

    <application

        android:allowBackup="true"

        android:icon="@drawable/ic_launcher"

        android:label="@string/app_name"

        android:theme="@style/AppTheme" >

        <activity

            android:name="com.solomon.splashscreenexample.SplashscreenActivity"

            android:label="@string/app_name" >

            <intent-filter>

                <action android:name="android.intent.action.MAIN" />

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

            </intent-filter>

        </activity>

  // Here we are declaring MainpageActivity       

   <activity

            android:name="com.solomon.splashscreenexample.MainpageActivity">

          

        </activity>

    </application>

</manifest>
