[JAVA] I have a question. I get an error when playing a video in Listview on android.

I am creating an android app with java in android studio. It is an application that displays tweets around 10 km when you tap google map. problem I want to display a video when displaying the acquired tweets in Listview. ・ The video is displayed even though it is not the corresponding tweet ・ Drops when displaying a video -The video does not play even if the list view is returned. The problem arises. I'm playing a video using SurfaceView and media player. Thank you for the solution.

The following code public class MapsSubActivity extends ListActivity {

private TweetAdapter01 mAdapter;
private Twitter mTwitter;
public SurfaceView mSurfaceView;
public SurfaceHolder mHolder;
public MediaPlayer mMediaPlayer;
public String path1 = "";
public void onCreate(Bundle savedInstanceState) {
    mAdapter = new TweetAdapter01(this);

private void reloadTimeLine() {
    AsyncTask<Void, Void, List<Status>> task = new AsyncTask<Void, Void, List<twitter4j.Status>>() {

//経度緯度の受け渡し Intent intent = getIntent(); String strLat = intent.getStringExtra ("strLat"); // Exclude word String strLong = intent.getStringExtra ("strLong"); // Specify account double dLat = Double.parseDouble(strLat); double dLong = Double.parseDouble(strLong);

        public final String API_KEY = "XXXXXXX";
        public final String API_SECRET = "XXXXXXX";
        public final String ACCESS_TOKEN = "XXXXXXX";
        public final String ACCESS_TOKEN_SECRET = "XXXXXXX";

        protected List<twitter4j.Status> doInBackground(Void... params) {
            try {

                String strQuery = null;
                Twitter tw = new TwitterFactory().getInstance();
                tw.setOAuthConsumer(API_KEY, API_SECRET);
                AccessToken at = new AccessToken(ACCESS_TOKEN, ACCESS_TOKEN_SECRET);
                ArrayList<twitter4j.Status> list = new ArrayList<twitter4j.Status>();
                Query query = new Query();                  
                    GeoLocation geo = new GeoLocation(dLat, dLong);
                    query.setGeoCode(geo, 10.0, Query.KILOMETERS);
                    QueryResult result = tw.search(query);
                    String str = String.valueOf(result.getCount());

                    for (twitter4j.Status tweet : result.getTweets()) {
                    if (result.hasNext()) {
                        query = result.nextQuery();
