Solution

  • I've also wanted to implement such feature, so I wrote it myself to "copy" YouTube's behavior. It's almost the same. You can find the library here including a sample app: https://github.com/vkay94/DoubleTapPlayerView

    The instructions are written in the README, but due to Stackoverflow principals:

    0) Requirements:

    1) Include it to your gradle (it's hosted on jitpack.io so you've got to add it to your respositories):

    allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

dependencies {
    implementation 'com.github.vkay94:DoubleTapPlayerView:1.0.0'
}

    2) Add the views inside your XML:

    <FrameLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >
    
    <com.github.vkay94.dtpv.DoubleTapPlayerView
        android:id="@+id/playerView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        
        app:dtpv_controller="@+id/youtube_overlay" />

    <com.github.vkay94.dtpv.youtube.YouTubeOverlay
        android:id="@+id/youtube_overlay"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:visibility="invisible"
        
        app:yt_playerView="@+id/playerView" />
</FrameLayout>

    3) Set it up inside your activity:

    youtube_overlay
    .performListener(object : YouTubeOverlay.PerformListener {
        override fun onAnimationStart() {
            // Do UI changes when circle scaling animation starts (e.g. hide controller views)
            youtube_overlay.visibility = View.VISIBLE
        }

        override fun onAnimationEnd() {
            // Do UI changes when circle scaling animation starts (e.g. show controller views)
            youtube_overlay.visibility = View.GONE
        }
    })
    // Uncomment this line if you haven't set yt_playerView in XML
    // .playerView(playerView)

// Uncomment this line if you haven't set dtpv_controller in XML 
// playerView.controller(youtube_overlay)

// Call this method whenever the player is released and recreated
youtube_overlay.player(simpleExoPlayer)
