202 MyClub Apps Demo How To Create Walkthrough Screen In Android

1) Create a new project using Tabbed Activity

Create a Tabbed Activity (refer this tutorial, http://android-steps.blogspot.my/2015/07/106-android-studio-15-tabbed-activity.html).

Give a name “Walkthrough” to the activity.

2) Prepare the resources

2.1) Create/Edit the Apps Title image

We can use online services like www.flamingtext.com to create a simple logo for the apps title.

(File: splashtitle_transparent.png)

2.2) Create/Edit the image icons

We can use Image Online Editors like www.pixlr.com/editor to edit images and icons.

This apps uses one background image, three icon images and one title image as shown below. They are provided here so that you can download them as use in your project as well.

202-MyClub1_Drawable.zip

Download the zip file above and put the contents under your drawable folder as shown below.

2.3) Define the suitable Color Scheme

Use the Online Tools like www.materialpalette.com to generate a suitable Color Scheme for the apps.

File: res/values/colors.xml

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

</resources>

3) Edit Layout Files

We want the page to appear full screen.

Therefore, delete the AppBarLayout widget element.

File: res/layout/activity_walkthrough.xml

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

<android.support.design.widget.CoordinatorLayout

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

xmlns:app="http://schemas.android.com/apk/res-auto"

xmlns:tools="http://schemas.android.com/tools"

android:id="@+id/main_content"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:fitsSystemWindows="true"

tools:context="com.notarazi.myclub1.Walkthrough">

<android.support.design.widget.AppBarLayout

android:id="@+id/appbar"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:paddingTop="@dimen/appbar_padding_top"

android:theme="@style/AppTheme.AppBarOverlay">

<android.support.v7.widget.Toolbar

android:id="@+id/toolbar"

android:layout_width="match_parent"

android:layout_height="?attr/actionBarSize"

android:background="?attr/colorPrimary"

app:layout_scrollFlags="scroll|enterAlways"

app:popupTheme="@style/AppTheme.PopupOverlay">

</android.support.v7.widget.Toolbar>

<android.support.design.widget.TabLayout

android:id="@+id/tabs"

android:layout_width="match_parent"

android:layout_height="wrap_content" />

</android.support.design.widget.AppBarLayout>

<android.support.v4.view.ViewPager

android:id="@+id/container"

android:layout_width="match_parent"

android:layout_height="match_parent"

app:layout_behavior="@string/appbar_scrolling_view_behavior" />

<android.support.design.widget.FloatingActionButton

android:id="@+id/fab"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_gravity="end|bottom"

android:layout_margin="@dimen/fab_margin"

android:src="@android:drawable/ic_dialog_email" />

</android.support.design.widget.CoordinatorLayout>

Modify the fragment layout so that it contains a background image, ImageView and TextView with additional attributes.

File: res/layout/fragment_walkthrough.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"

android:background="@drawable/splashbackground"

tools:context="com.notarazi.myclub1.Walkthrough$PlaceholderFragment"

<ImageView

android:id="@+id/ivw_walkthrough"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_centerHorizontal="true"

android:layout_centerVertical="true"

android:background="@drawable/splashtitle_transparent"

<TextView

android:id="@+id/tvw_walkthrough"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="..."

android:textSize="15pt"

android:textStyle="bold"

android:layout_centerHorizontal="true"

android:textAlignment="center"

android:layout_below="@id/ivw_walkthrough"

android:textColor="#ffffff"

android:shadowColor="#000000"

android:shadowDx="-2"

android:shadowDy="-2"

android:shadowRadius="1"

</RelativeLayout>

OUTCOME.

4) Edit the Controller File

Our Controller File, ie Walkthrough.java will implement the following logic…

… ViewPager contains 4 fragment pages

… automatically switches the ViewPager fragment page in 3 seconds duration

… automatically loads the Image and Text according to the fragment page index

… automatically starts the Next Activity after the last fragment page is displayed

… the apps user can skip the fragment pages by tapping the Floating Action Button

We use a runnable class to handle the delay process.
