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 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 grantedneededPersmissions⇾ permission which are needed to be granted to move further from that slideMessageButtonBehaviour⇾ 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 screenhideBackButton()⇾ hides any button on the left bottom of screenenableLastSlideAlphaExitTransition()⇾ 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:
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
