Android Material Intro Screen

Material intro screen is inspired by Material Intro and developed with love from scratch. I decided to rewrite completely almost all features in order to make Android intro screen easy to use for everyone and extensible as possible.

Features

• Easily add new slides
• Custom slides
• Parallax slides
• Easy extensible api
• Android TV support!
• Material design at it's best!!!

Simple slide	Custom slide	Permission slide	Finish slide

Usage

Step 1:

Add gradle dependecy

dependencies {
  compile 'agency.tango.android:material-intro-screen:{latest_release}'
}

Step 2:

First, your intro activity class needs to extend MaterialIntroActivity:

public class IntroActivity extends MaterialIntroActivity

Step 3:

Add activity to manifest with defined theme:

        <activity
            android:name=".IntroActivity"
            android:theme="@style/Theme.Intro" />

Step 4:

Add slides:

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

        addSlide(new SlideFragmentBuilder()
                .backgroundColor(R.color.colorPrimary)
                .buttonsColor(R.color.colorAccent)
                .possiblePermissions(new String[]{Manifest.permission.CALL_PHONE, Manifest.permission.READ_SMS})
                .neededPermissions(new String[]{Manifest.permission.CAMERA, Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION})
                .image(agency.tango.materialintroscreen.R.drawable.ic_next)
                .title("title 3")
                .description("Description 3")
                .build(),
                new MessageButtonBehaviour(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        showMessage("We provide solutions to make you love your work");
                    }
                }, "Work with love"));
}

Explanation of SlideFragment usage:

• possiblePermissions ⇾ permissions which are not necessary to be granted
• neededPersmissions ⇾ permission which are needed to be granted to move further from that slide
• MessageButtonBehaviour ⇾ create a new instance only if you want to have a custom action or text on a message button

Step 5:

Customize Intro Activity:

• setSkipButtonVisible() ⇾ show skip button instead of back button on the left bottom of screen
• hideBackButton() ⇾ hides any button on the left bottom of screen
• enableLastSlideAlphaExitTransition() ⇾ set if the last slide should disapear with alpha hiding effect

Customizing view animations:

You can set enter, default and exit translation for every view in intro activity. To achive this you need to get translation wrapper for chosen view (for example: getNextButtonTranslationWrapper()) and set there new class which will implement IViewTranslation

getBackButtonTranslationWrapper()
                .setEnterTranslation(new IViewTranslation() {
                    @Override
                    public void translate(View view, @FloatRange(from = 0, to = 1.0) float percentage) {
                        view.setAlpha(percentage);
                    }
                });

Available translation wrappers:

• getNextButtonTranslationWrapper()
• getBackButtonTranslationWrapper()
• getPageIndicatorTranslationWrapper()
• getViewPagerTranslationWrapper()
• getSkipButtonTranslationWrapper()

Custom slides

Of course you are able to implement completely custom slides. You only need to extend SlideFragment and override following functions:

• backgroundColor()
• buttonsColor()
• canMoveFurther() (only if you want to stop user from being able to move further before he will do some action)
• cantMoveFurtherErrorMessage() (as above)

If you want to use parallax in a fragment please use one of the below views:

• ParallaxFrameLayout
• ParallaxLinearLayout
• ParallaxRelativeLayout

And set there the app:layout_parallaxFactor attribute:

<agency.tango.materialintroscreen.parallax.ParallaxLinearLayout
xmlns:android="http://schemas.android.com/apk/res/android">

    <ImageView
        android:id="@+id/image_slide"
        app:layout_parallaxFactor="0.6"/>

All features which are not available in simple Slide Fragment are shown here: Custom Slide

Things I have used to create this

• For parallax I have used files from Material Intro by @HeinrichReimer
• InkPageIndicator.java by @NickButcher
• Images used to create sample app are from freepik
• For over scroll effect on last slide I have partially used Android-Overscroll-ViewPager
