81.3 Entering Picture-in-Picture Mode

The enterPipMode onClick callback method now needs to be added to the MainActivity.kt class file. Locate this file, open it in the code editor and add this method as follows:

.

.

import android.app.PictureInPictureParams

import android.util.Rational

import android.view.View

import android.content.res.Configuration

.

.

fun enterPipMode(view: View) {

 

    val rational = Rational(videoView1.width,

            videoView1.height)

 

    val params = PictureInPictureParams.Builder()

            .setAspectRatio(rational)

            .build()

 

    pipButton.visibility = View.INVISIBLE

    videoView1.setMediaController(null)
