Несколько выпусков VideoView ⇐ Android

[Anonymous]

У меня есть приложение, содержащее 5 кнопку. Каждая кнопка открывает различные видеовиусы. When I create code I have red mark under (new MediaController(this)) I can't find how to fix it.
After apply changed to: (new MediaController(this)) I get another error
My code:
MultipleButton class:
public class MultipleButton extends Activity {
String night;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}

public void handleClick(View v){
//Create an intent to start the new activity.
Intent intent = new Intent();
intent.setClass(this,My_videos.clpublic class My_videos extends Activity {
private Button button;
private VideoView vid;
String night;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.video);

initializeVideoViews();
}

private void initializeVideoViews() {
String night = getIntent().getStringExtra("video");

if (night.equalsIgnoreCase("button1")) {
button = (Button) findViewById(R.id.button1);

button.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
vid = (VideoView) findViewById(R.id.videoView1);
vid.setVideoURI(Uri.parse("android.resource://" +
getPackageName() + "/" + R.raw.a));
vid.setMediaController(new MediaController(My_videos.this));
vid.requestFocus();
vid.start();
}
});
} else if (night.equalsIgnoreCase("button2")) {
button = (Button) findViewById(R.id.button2);
button.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {

vid = (VideoView) findViewById(R.id.videoView1);
vid.setVideoURI(Uri.parse("android.resource://" +
getPackageName() + "/" + R.raw.b));
vid.setMediaController(new MediaController(My_videos.this));
vid.requestFocus();
}
});
} else if (night.equalsIgnoreCase("button3")) {
button = (Button) findViewById(R.id.button3);

button.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
vid = (VideoView) findViewById(R.id.videoView1);
vid.setVideoURI(Uri.parse("android.resource://" +
getPackageName() + "/" + R.raw.c));
vid.setMediaController(new MediaController(My_videos.this));
vid.requestFocus();
}
});
} else if (night.equalsIgnoreCase("button4")) {
button = (Button) findViewById(R.id.button4);

button.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
vid = (VideoView) findViewById(R.id.videoView1);
vid.setVideoURI(Uri.parse("android.resource://" +
getPackageName() + "/" + R.raw.d));
vid.setMediaController(new MediaController(My_videos.this));
vid.requestFocus();
}
});
} else if (night.equalsIgnoreCase("button5")) {
button = (Button) findViewById(R.id.button5);

button.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
vid = (VideoView) findViewById(R.id.videoView1);
vid.setVideoURI(Uri.parse("android.resource://" +
getPackageName() + "/" + R.raw.e));
vid.setMediaController(new MediaController(My_videos.this));
vid.requestFocus();
}
});
}
}
}
