Fullscreen the Exoplayer

Question

I try to show the show video (.mp4) with exoplayer in RecyclerView and ViewPager. I show the video controller with custom layo

Answer 1

Exoplayer doesn't provide the fullscreen so here is the workaround that worked for me. Here I have restricted the Screen to rotate and manually changing the orientation programmatically change the width and height of the player_view and has set the visibility of the toolbar gone. Used Data Binding and Kotlin.

Follows a code block for XML

Changes in Android Manifest

Check the orientation and rotate it via the following code

mBinding.playerView.exo_fullscreen_btn.setOnClickListener {
        if ((activity as TrainingVideoActivity).checkLandscapeOrientation()) {
            (activity as TrainingVideoActivity).changeOrientationToLandscape(false)

        } else {
            (activity as TrainingVideoActivity).changeOrientationToLandscape(true)

        }

    }

Methods Signature are following

/**
 * Changes the Orientation
 * @param shouldLandscape
 */
fun changeOrientationToLandscape(shouldLandscape: Boolean) {
    requestedOrientation = if (shouldLandscape) {
        ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE
    } else {
        ActivityInfo.SCREEN_ORIENTATION_PORTRAIT
    }
}

/**
 * Checks the Orientation
 * And returns true if Landscape else false
 */
fun checkLandscapeOrientation() : Boolean {
    val orientation = resources.configuration.orientation
    return orientation == Configuration.ORIENTATION_LANDSCAPE
}

Now Just Override onConfigurationChanged method in your fragment/activity, since here I have used Fragment. So here I have changed the width/height of the parent container in which ExoplayerView is placed.

/**
 * Used for Showing Video on Full Screen
 * @param newConfig
 * Used EXO_PLAYER_VIEW_HEIGHT as 250
 */
override fun onConfigurationChanged(newConfig: Configuration) {
    super.onConfigurationChanged(newConfig)
    if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
        hideToolbarAndShowFullScreen()
        mBinding.playerView.exo_fullscreen_btn.setImageDrawable(ContextCompat.getDrawable(activity!!, R.drawable.ic_shrink))
        val params = mBinding.videoPlayerContainer.layoutParams as ConstraintLayout.LayoutParams
        params.width = ViewGroup.LayoutParams.MATCH_PARENT
        params.height = ViewGroup.LayoutParams.MATCH_PARENT
        mBinding.videoPlayerContainer.layoutParams = params
    } else {
        showToolbarAndClearFullScreen()
        mBinding.playerView.exo_fullscreen_btn.setImageDrawable(ContextCompat.getDrawable(activity!!, R.drawable.ic_fullscreen))
        val params = mBinding.videoPlayerContainer.layoutParams as ConstraintLayout.LayoutParams
        val factor = mBinding.playerView.context.resources.displayMetrics.density
        params.width = ViewGroup.LayoutParams.MATCH_PARENT
        params.height = (EXO_PLAYER_VIEW_HEIGHT * factor).toInt()
        mBinding.videoPlayerContainer.layoutParams = params
    }
}

/**
 * Show the Toolbar and reset to original in the Portrait Mode
 */
private fun showToolbarAndClearFullScreen() {
    (activity as TrainingVideoActivity).supportActionBar!!.show()
    (activity as TrainingVideoActivity).window.clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN)

}

Lastly, XML for the player_controller

Let me know if this works.
