Make Android intro screen easy to use for everyone and extensible as possible

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!!!

Usage

Step 1:

Add gradle dependecy

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

Step 2:

First, your [intro activity][Intro Activity] class needs to extend MaterialIntroActivity:

public class IntroActivity extends MaterialIntroActivity

Step 3:

Add activity to [manifest][Manifest] with defined theme:

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

Step 4:

[Add slides:][Intro Activity]

 @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][TranslationWrapper]:

• 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][ParallaxFrame]
• [ParallaxLinearLayout][ParallaxLinear]
• [ParallaxRelativeLayout][ParallaxRelative]

And set there the [app:layout_parallaxFactor][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"/>
