What it is
A short Android Developers video in which Sean McQuillan shows how to build keyframe-style animations in Android using ConstraintLayout and ConstraintSet. It explains defining start and end layouts as constraint sets and animating between them with little code.

I have recently came across to this video Keyframe Animations with ConstraintLayout and ConstraintSet [this video] , it seems pretty cool . so Implemented this way following the steps showed in a blog post [LINK] . There is just one difference though between the blog and my use case . I am working with fragment . I thought theoretically implementation supposed to be as it is . Here is my work around for keyframe animation on two constrainSet() [LINK] ConstrainLayout initial (point A so to speak) <?xml version="1.0" encoding="utf-8"?> <android.support.constraint.ConstraintLayout xmlns:android=" [LINK] " xmlns:tools=" [LINK] " xmlns:app=" [LINK] " android:layout_width="match_parent" android:layout_

I'd like to make enter animation for activity using ConstraintSet, as it's shown in this video: [this video] . The problem is I don't know in which lifecycle method to put code to make the transition visible to user. In onCreate I'm calling: setContentView(R.layout.layout_first_keyframe_detail); topConstraintLayout = findViewById(R.id.top_constraint_layout); constraintSet = new ConstraintSet(); constraintSet.clone(this, R.layout.layout_detail_top); and then I'd like to call: TransitionManager.beginDelayedTransition(topConstraintLayout); constraintSet.applyTo(topConstraintLayout); when activity is already visible. Unfortunately I don't find any lifecycle method to do this.

This is a basic example of creating a custom draggable drawer. These are the references I went through. To detect drag / fling gesture I have used GestureDetectorCompat, and I referred to : [LINK] To create drawer open and close animations I referred to : [this video] Please note that this is a very basic example. You can use this as the base to create your end goal. You will have to filter out unwanted drag / fling callbacks you receive. You will have to ignore the taps that you'll get on the drawer. Here's the implementation. MainActivity.java import androidx.appcompat.app.AppCompatActivity; import androidx.constraintlayout.widget.ConstraintLayout; import androidx.constraintlayout.widget.Constr
