Intro Screen Slider Android Tutorial

Hi there, In this tutorial, I am gonna teach you how you can create an introductory slide show for your android application. The point to ponder about this task is that the slide show must run just for once after the installation. From the second time, the app must open with some home screen. So lets begin our Intro Screen Slider Android Tutorial.

Creating a New Android Studio Project

First create a new project. You can do the same in your existing application.
I just created a project named AppIntro.

Adding AppIntro dependency

In this Screen Slider Android Tutorial we will be using AppIntro library.
So the first thing we need to add this library into our project. For this just go to your app level build.gradle file and add the following line inside dependencies block and then just sync your project.

    compile 'com.github.paolorotolo:appintro:4.0.0'

1	compile 'com.github.paolorotolo:appintro:4.0.0'

Creating a Fragment to Show Different Slides

Next, we need to create a class named SampleSlide.java through which the view of different slides is inflated.

package com.example.manish.simplifiedcodingappintro;

import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

public class SampleSlide extends Fragment {

    private static final String ARG_LAYOUT_RES_ID = "layoutResId";

    public static SampleSlide newInstance(int layoutResId) {
        SampleSlide sampleSlide = new SampleSlide();

        Bundle args = new Bundle();
        args.putInt(ARG_LAYOUT_RES_ID, layoutResId);
        sampleSlide.setArguments(args);

        return sampleSlide;
    }

    private int layoutResId;

    public SampleSlide() {}

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

        if(getArguments() != null && getArguments().containsKey(ARG_LAYOUT_RES_ID))
            layoutResId = getArguments().getInt(ARG_LAYOUT_RES_ID);
    }

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        return inflater.inflate(layoutResId, container, false);
    }

}

package com.example.manish.simplifiedcodingappintro;

import android.os.Bundle;

import android.support.annotation.Nullable;

import android.support.v4.app.Fragment;

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup;

public class SampleSlide extends Fragment {

private static final String ARG_LAYOUT_RES_ID = "layoutResId";

public static SampleSlide newInstance(int layoutResId) {

SampleSlide sampleSlide = new SampleSlide();

Bundle args = new Bundle();

args.putInt(ARG_LAYOUT_RES_ID, layoutResId);

sampleSlide.setArguments(args);

return sampleSlide;

}

private int layoutResId;

public SampleSlide() {}

@Override

public void onCreate(@Nullable Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

if(getArguments() != null && getArguments().containsKey(ARG_LAYOUT_RES_ID))

layoutResId = getArguments().getInt(ARG_LAYOUT_RES_ID);

}

@Nullable

@Override

public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {

return inflater.inflate(layoutResId, container, false);

}

Creating Intro Screen Sliders

Next, we need to create a class named DefaultIntro.java.

package com.example.manish.simplifiedcodingappintro;

import android.Manifest;
import android.content.Intent;
import android.graphics.Color;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.View;
import android.widget.Toast;

import com.github.paolorotolo.appintro.AppIntro;


public final class DefaultIntro extends AppIntro {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
//Down here, we add the xml layouts into sample slide inflater.
        addSlide(SampleSlide.newInstance(R.layout.intro));
        addSlide(SampleSlide.newInstance(R.layout.intro2));
        addSlide(SampleSlide.newInstance(R.layout.intro3));
        addSlide(SampleSlide.newInstance(R.layout.intro4));


        showStatusBar(true);

        setDepthAnimation();

    }



    @Override
    public void onDonePressed(Fragment currentFragment) {
        super.onDonePressed(currentFragment);

        loadMainActivity();
    }

    private void loadMainActivity(){
        Intent intent = new Intent(this, MainActivity.class);
        startActivity(intent);
    }

    @Override
    public void onSkipPressed(Fragment currentFragment) {
        super.onSkipPressed(currentFragment);
        loadMainActivity();
        Toast.makeText(getApplicationContext(), getString(R.string.skip), Toast.LENGTH_SHORT).show();
    }

    public void getStarted(View v){
        loadMainActivity();
    }
}

package com.example.manish.simplifiedcodingappintro;

import android.Manifest;

import android.content.Intent;

import android.graphics.Color;

import android.os.Bundle;

import android.support.v4.app.Fragment;

import android.view.View;

import android.widget.Toast;

import com.github.paolorotolo.appintro.AppIntro;

public final class DefaultIntro extends AppIntro {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

//Down here, we add the xml layouts into sample slide inflater.

addSlide(SampleSlide.newInstance(R.layout.intro));

addSlide(SampleSlide.newInstance(R.layout.intro2));

addSlide(SampleSlide.newInstance(R.layout.intro3));

addSlide(SampleSlide.newInstance(R.layout.intro4));

showStatusBar(true);

setDepthAnimation();

}

@Override

public void onDonePressed(Fragment currentFragment) {

super.onDonePressed(currentFragment);

loadMainActivity();

}

private void loadMainActivity(){

Intent intent = new Intent(this, MainActivity.class);

startActivity(intent);

}

@Override

public void onSkipPressed(Fragment currentFragment) {

super.onSkipPressed(currentFragment);

loadMainActivity();

Toast.makeText(getApplicationContext(), getString(R.string.skip), Toast.LENGTH_SHORT).show();

}

public void getStarted(View v){

loadMainActivity();

}

Next, we need to create a class named Config.java to store constants.

public class Config {

    public static String FLAG="It the start";
}

public class Config {

public static String FLAG="It the start";

}

Next, we need to configure our MainActivity.java. In order to make sure that the appintro runs just for once, we make use of Thread and SharedPreferences as it can be seen down into the code of MainActivity.

package com.example.manish.simplifiedcodingappintro;

import android.content.Context;
import android.content.Intent;
import android.content.SharedPreferences;
import android.preference.Preference;
import android.preference.PreferenceManager;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Thread t=new Thread(new Runnable() {
            @Override
            public void run() {

              SharedPreferences  sharedPreferences = getSharedPreferences(Config.FLAG, Context.MODE_PRIVATE);

                if(sharedPreferences.getBoolean(Config.FLAG,true)){


                    startActivity(new Intent(MainActivity.this,DefaultIntro.class));

                    SharedPreferences.Editor e=sharedPreferences.edit();

                    e.putBoolean(Config.FLAG,false);

                    e.apply();
                }
            }
        });
       t.start();
    }
}

package com.example.manish.simplifiedcodingappintro;

import android.content.Context;

import android.content.Intent;

import android.content.SharedPreferences;

import android.preference.Preference;

import android.preference.PreferenceManager;

import android.support.v7.app.AppCompatActivity;

import android.os.Bundle;

import android.widget.Toast;

public class MainActivity extends AppCompatActivity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

Thread t=new Thread(new Runnable() {

@Override

public void run() {

SharedPreferences sharedPreferences = getSharedPreferences(Config.FLAG, Context.MODE_PRIVATE);

if(sharedPreferences.getBoolean(Config.FLAG,true)){

startActivity(new Intent(MainActivity.this,DefaultIntro.class));

SharedPreferences.Editor e=sharedPreferences.edit();

e.putBoolean(Config.FLAG,false);

e.apply();

}

});

t.start();

}

Here, the Java part gets over. Now, we need to configure our design resources i.e. xml layouts.

Creating Layouts for Slider

Create a Layout resource file named intro.xml. This would be our first slide in the introduction.

Preview of intro4.xml

We are almost done. Just add this theme into your style resource file as follows

   <style name="FullscreenTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->
        <item name="android:windowTranslucentStatus">true</item>
    </style>

</style>

Now, we need some icons and drawables resource files to be added to the drawables . Download the zip below and then add all its content to the drawables.

Finally, mention DefaultIntro.java as an activity in your manifest as follows:-

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.manish.apptopintro22">

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name=".DefaultIntro"
            android:label="Intro Label"
            android:theme="@style/FullscreenTheme">

        </activity>
    </application>

</manifest>

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

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

package="com.example.manish.apptopintro22">

<application

android:allowBackup="true"

android:icon="@mipmap/ic_launcher"

android:label="@string/app_name"

android:supportsRtl="true"

android:theme="@style/AppTheme">

  Just replace the whole getString(R.string.skip) with the text you wish to see when skip is tapped in double quotes.

Nice one , but can do you have any idea where we can set the Animation mentioned in the library.
setFadeAnimation()
setZoomAnimation()
setFlowAnimation()
setSlideOverAnimation()
setDepthAnimation()
I can’t find any function in this example can you give me some idea.

  In the SampleSlide class, make sure that you import android .support.v4.app.Fragment
