Motion Layout Example

MotionLayout is a layout type that helps you manage motion and widget animation in your app. MotionLayout is a subclass of ConstraintLayout and builds upon its rich layout capabilities. As part of the ConstraintLayout library, MotionLayout is available as a support library and is backwards-compatible to API level 14.

Lets get into simple motion layout example code:

Follow these simple steps to start using MotionLayout in your project.

1: First you need to add the ConstraintLayout dependency:

Add the ConstraintLayout 2.0 dependency to your app’s build.gradle file. If you’re using AndroidX, add the following dependency:

dependencies {
    implementation 'androidx.constraintlayout:constraintlayout:2.0.0-beta1'
<span class="pln">}    </span>

dependencies {

implementation 'androidx.constraintlayout:constraintlayout:2.0.0-beta1'

If you not using the AndroidX, add the following support library dependency:

dependencies {
    implementation 'com.android.support.constraint:constraint-layout:2.0.0-beta1'
}

dependencies {

implementation 'com.android.support.constraint:constraint-layout:2.0.0-beta1'

}

</MotionScene>

The activity_main_motion file will be in res->xml directory, either you can create the file or it can be auto generated by the android studio. In the activity_main_motion.xml file we can provide various type of animations.

We can also use the constraint set to animate the layout for animation from start to end.

That’s it from my side for today, thanks for reading it until now.
