Getting Started

Android VideoView can be defined as below –

VideoView is subclass of View that are used to display a video file.

Different Attributes of Android VideoView Widget

Some of the popular attributes of videoView are –

Example of Android VideoView Using Kotlin

At first, we will create android application. Then, we will use videoView using kotlin in the application.

1. Creating New Project in Kotlin

Follow steps below to create new project. Please ignore the steps if you have already created the project.

Since we have a project now, we will modify xml and other files to use videoView using kotlin in the application.

2. Modify values folder

Open res/values/strings.xml file. Then, add below code into it.

<resources>
	<string name="app_name">VideoView</string>
	<string name="play">Play</string>
	<string name="pause">Pause</string>
	<string name="paused">Paused…</string>
	<string name="playing">Playing…</string>
</resources>

3. Use VideoView Widget in xml file

Open src/main/res/layout/activity_main.xml file and add below code into it.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
	xmlns:android="http://schemas.android.com/apk/res/android"
	android:layout_width="match_parent"
	android:layout_height="match_parent"
	android:gravity="center"
	android:orientation="vertical">

	<Button
		android:id="@+id/button"
		android:layout_width="wrap_content"
		android:layout_height="wrap_content"
		android:layout_marginBottom="5dp"
		android:layout_marginTop="5dp"
		android:text="@string/play"/>

	<VideoView
		android:id="@+id/videoView"
		android:layout_width="match_parent"
		android:layout_height="wrap_content"
		android:layout_margin="5dp"/>

</LinearLayout>

In activity_main.xml file, we have defined VideoView and Button widgets. Now, we will access this widgets in kotlin file. Then, we will perform some operations on it.

4. Access VideoView Widget in Kotlin file

Open src/main/java/com.tutorialwing.videoview/MainActivity.kt file and add below code into it.

package com.tutorialwing.videoview

import android.net.Uri
import android.os.Bundle
import android.support.v7.app.AppCompatActivity
import android.widget.Button
import android.widget.Toast
import android.widget.VideoView

class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        val videoView = findViewById<VideoView>(R.id.videoView)
        val path = "android.resource://" + packageName + "/" + R.raw.a
        videoView?.setVideoURI(Uri.parse(path))

        val button = findViewById<Button>(R.id.button)
        button?.setOnClickListener({
            val isPlaying = videoView.isPlaying
            button.setText(if (isPlaying) R.string.play else R.string.pause)

            val msg = getString(if (isPlaying) R.string.paused else R.string.playing)
            Toast.makeText(this@MainActivity, msg, Toast.LENGTH_SHORT).show()
            if (isPlaying) {
                videoView.pause()
            } else {
                videoView.start()
            }
        })
    }
}

We have accessed Button and VideoView using kotlin file (i.e. MainActivity.kt). After that, we have accessed the path of video resource stored in res/raw folder. Note that you will have to create raw folder under main/res folder in the application. We store resources such as audio, video etc. in raw folder.

We have also set click listener in button to play/pause video in the videoView.

Since AndroidManifest.xml file is very important in any android application, we are also going to see the content inside this file.

AndroidManifest.xml file

Code inside main/AndroidManifest.xml file is as below.

<?xml version="1.0" encoding="utf-8"?>
<manifest package="com.tutorialwing.videoview"
		  xmlns:android="http://schemas.android.com/apk/res/android">

	<application
		android:allowBackup="true"
		android:icon="@mipmap/ic_launcher"
		android:label="@string/app_name"
		android:roundIcon="@mipmap/ic_launcher_round"
		android:supportsRtl="true"
		android:theme="@style/AppTheme">
		<activity android:name=".MainActivity">
			<intent-filter>
				<action android:name="android.intent.action.MAIN"/>

				<category android:name="android.intent.category.LAUNCHER"/>
			</intent-filter>
		</activity>
	</application>

</manifest>

When we run the program, we will get output as shown above.

That’s end of our tutorial on Android videoView using Kotlin.
