Listview item highlight color changing while scrolling, and multiple items are getting highlighted where only a single item has been clicked

I searched the google and even the stackoverflow for the solution, but nothing worked and this is really making me insane now. :(
I want the only item to be highlighted is the one which I click on the listview. When I click on the item, it gets highlighted in red color. But once I scroll the list, I find multiple items are getting highlighted with red, and coming back to the item I find it turned to default color, that is non-highlighted mode. Getting crazy over this, working on this from the past 3 hours still unable to find a solution. :( Would really appreciate your advice. I know this is my third post in a day but I am quite new to android, so stumbling over this a few times. My code is stated below-

I am new here. I was asked by my professor to play other audio while the same video is being played(for example a person doesn't understand English and wants the the app to play french ). I have used video view. One possible method was to mute the present audio and play the french audio stored in my sdcard. but video view supports no muting( i couldn't find one). I read that i have to go for media player instead of video view.
Please help...!! what should i do... Thanks in advance.

if you want to get access to the MediaPlayer of a VideoView you have to call MediaPlayer.OnPreparedListener and MediaPlayer.OnCompletionListener, then you can call setVolume(0f, 0f); function to set the volume to 0.
Do this:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_video);
VideoView videoView = (VideoView)this.findViewById(R.id.VVSimpleVideo);
MediaController mc = new MediaController(this);
mc.setAnchorView(videoView);
mc.setMediaPlayer(videoView);
videoView.setMediaController(mc);
String _path = "/mnt/sdcard/Movies/video5.mp4";
videoView.setVideoPath(_path);
videoView.setOnPreparedListener(PreparedListener);
videoView.requestFocus();
//Dont start your video here
//videoView.start();
}
MediaPlayer.OnPreparedListener PreparedListener = new MediaPlayer.OnPreparedListener(){
#Override
public void onPrepared(MediaPlayer m) {
try {
if (m.isPlaying()) {
m.stop();
m.release();
m = new MediaPlayer();
}
m.setVolume(0f, 0f);
m.setLooping(false);
m.start();
} catch (Exception e) {
e.printStackTrace();
}
}
};

Video not displayed with 2 instances of mediaplayer

I am trying to use two instances of mediaplayer. When the first instance is played the second instance is prepared in another thread.and when first instance completes the file the second instance is started.
Problem: the second instance plays only audio, video is not visible.
Observation:If i prepare the second instance with the same surface holder as that of the first and start after first instance is completed it works fine.

Please take a look at the following thread:

It looks like using two SurfaceViews was not intended by the Android developers.

mediaplayer.start();
}
});
}
}

right code but wrong api level~
it's not every api level supports this way to play a media,http live streaming ,may be you need api level 10 or higher

Android Audio Streaming

Does any one have code they know will run android audio stream from a URL, that will work in android OS 2.2. I have looked on the developer site and there code doesn't seem to work for me. Some of the other code or tutorials are for older versions of android.
This was the code from the code i ve been using(won't work):
import java.io.IOException;
import android.app.Activity;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class Radio extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.radio);
final MediaPlayer mp = new MediaPlayer();
try {
mp.setDataSource(URL);
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
mp.prepare();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
// This is code for a button that starts the stream when clicked
Button bRadio = (Button) findViewById(R.id.button_stream);
bRadio.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View V) {
mp.start();
}
});
}
}

As you are setting datasource to URL, use mp.prepareAsync() instead of mp.prepare().

if you are ok with JNI, there is some sample code here:
the creating JNI URI player is liking this:
// configure audio source
SLDataLocator_URI loc_uri = {SL_DATALOCATOR_URI, (SLchar *) uri_utf8};
SLDataFormat_MIME format_mime = {SL_DATAFORMAT_MIME, NULL, SL_CONTAINERTYPE_UNSPECIFIED};
SLDataSource audioSrc = {&loc_uri, &format_mime};
// configure audio sink
SLDataLocator_OutputMix loc_outmix = {SL_DATALOCATOR_OUTPUTMIX, outputMixObject};
SLDataSink audioSnk = {&loc_outmix, NULL};
// create audio player
const SLInterfaceID ids[3] = {SL_IID_SEEK, SL_IID_MUTESOLO, SL_IID_VOLUME};
const SLboolean req[3] = {SL_BOOLEAN_TRUE, SL_BOOLEAN_TRUE, SL_BOOLEAN_TRUE};
(*engineEngine)->CreateAudioPlayer(engineEngine, &uriPlayerObject, &audioSrc,&audioSnk, 3, ids, req);
(*uriPlayerObject)->Realize(uriPlayerObject, SL_BOOLEAN_FALSE);
(*uriPlayerObject)->GetInterface(uriPlayerObject, SL_IID_PLAY, &uriPlayerPlay);
... get other interfaces...
then you could play:
(*uriPlayerPlay)->SetPlayState(uriPlayerPlay,SL_PLAYSTATE_PLAYING);
