Using VideoView to play mp4, with MediaController enable/disable

Example to play mp4 on SDCard/ExternalStorage using android.widget.VideoView. You can also enable/disable the MediaController, contains the buttons like "Play/Pause", "Rewind", "Fast Forward" and a progress slider, by calling VideoView.setMediaController().

With the MediaController set, tap on the video (or the VideoView) to display the controller.


Example code:
package com.example.androidvideoview;

import java.io.File;

import android.support.v7.app.ActionBarActivity;
import android.widget.CompoundButton;
import android.widget.CompoundButton.OnCheckedChangeListener;
import android.widget.MediaController;
import android.widget.Toast;
import android.widget.ToggleButton;
import android.widget.VideoView;
import android.os.Bundle;
import android.os.Environment;

public class MainActivity extends ActionBarActivity {

ToggleButton enableMediaController;
VideoView myVideoView;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

enableMediaController = (ToggleButton)findViewById(R.id.enableMediaController);
myVideoView = (VideoView)findViewById(R.id.myvideoview);
myVideoView.setVideoPath(getViewSrc());
myVideoView.requestFocus();
myVideoView.start();

setMediaController();

enableMediaController.setOnCheckedChangeListener(new OnCheckedChangeListener(){

@Override
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
setMediaController();
}});
}

private void setMediaController(){
if(enableMediaController.isChecked()){
myVideoView.setMediaController(new MediaController(this));
}else{
myVideoView.setMediaController(null);
}
}

private String getViewSrc(){
File extStorageDirectory = Environment.getExternalStorageDirectory();
String s = extStorageDirectory.getAbsolutePath() + "/test.mp4";
Toast.makeText(MainActivity.this, s, Toast.LENGTH_SHORT).show();
return s;
}
}

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.example.androidvideoview.MainActivity" >

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="android-coding.blogspot.com"
android:textSize="24dp"
android:textStyle="bold" />

<ToggleButton
android:id="@+id/enableMediaController"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textOn="Disable MediaController"
android:textOff="Enable MediaController"
android:checked="true"/>
<VideoView
android:id="@+id/myvideoview"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />

</LinearLayout>

To play the file in SD Card, <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/> is needed in AndroidManifest.xml, otherwise "Can't play this video".
