getView in base adapter is not working

Question

I'm trying to create base adapter for Favorites.class so I can display items in it. The getView method is not being called and the Activity won't show any view.

BaseAdapter:

public class fYtAdapter extends BaseAdapter {
private List<SearchResult> mfVideoList = null;
private LayoutInflater mfLayoutInflater = null;
private Favorites fActivity = null;

public fYtAdapter(Favorites iActivity){
    fActivity = iActivity;
    mfLayoutInflater = LayoutInflater.from(fActivity);
}

public void setmVideoList(List<SearchResult> mVideoList){
    this.mfVideoList = mVideoList;
}

@Override
public int getCount() {
    return (mfVideoList == null)? (0):(mfVideoList.size());
}

@Override
public Object getItem(int position) {
    return (mfVideoList != null && mfVideoList.size()>position)? (mfVideoList.get(position)):(null);
}

@Override
public long getItemId(int position) {
    return position;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    final ViewHolder mHolder;
    if(convertView != null){
        mHolder = (ViewHolder)convertView.getTag();
    }else{
        mHolder = new ViewHolder();
        convertView = mfLayoutInflater.inflate(R.layout.view_video_item,null);
        mHolder.mVideoThumbnail = (ImageView)convertView.findViewById(R.id.video_thumbnail);
        mHolder.mVideoTitle = (TextView)convertView.findViewById(R.id.video_title);

        convertView.setTag(mHolder);
    }
    //Setting the data
    final SearchResult result = mfVideoList.get(position);
    mHolder.mVideoTitle.setText(result.getSnippet().getTitle());

    //Loading the image
    Picasso.with(fActivity).load(result.getSnippet().getThumbnails().getMedium().getUrl()).into(mHolder.mVideoThumbnail);
    return  convertView;
}

private class ViewHolder{
    private TextView mVideoTitle = null;
    private ImageView mVideoThumbnail = null;
}

}

Favorites.class

public class Favorites extends ActionBarActivity
    implements View.OnClickListener, AdapterView.OnItemClickListener, ServerResponseListener{


private LayoutInflater mLayoutInflater = null;
private ProgressDialog mLoadingDialog = null;
private fYtAdapter mYtadapter = null;
String vidID = null, vidTitle = null, vidThumbnail = null;
ListView mFavLsv;
Bundle extras;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.favorites_layout);
    getSupportActionBar().setTitle("Favorites");
    initializeViews();

    extras = getIntent().getExtras();
    this.vidID = extras.getString("id");
    this.vidTitle = extras.getString("title");
    this.vidThumbnail = extras.getString("thumbnail");
}
public void initializeViews(){
    mLayoutInflater = LayoutInflater.from(this);
    mFavLsv  = (ListView)findViewById(R.id.yt_fav_lst);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater menuInflater = getMenuInflater();
    menuInflater.inflate(R.menu.menu_main, menu);
    return super.onCreateOptionsMenu(menu);
}

//Not needed in this Activity
@Override
public void onClick(View v) {

}

//To start video
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
    Intent videoIntent = YouTubeStandalonePlayer.createVideoIntent(this, AppConstants.KEY, vidID);
    startActivity(videoIntent);
}

@Override
public void prepareRequest(Object... objects) {
    //Parse the response based on type of request
    Integer reqCode = (Integer) objects[0];

    if(reqCode == null || reqCode == 0)
        throw new NullPointerException("Request Code's value is Invalid.");
    String dialogMsg = null;
    switch(reqCode){
        case SEARCH_VIDEO:
            dialogMsg = SEARCH_VIDEO_MSG;
            break;
    }
    if(mLoadingDialog != null && !mLoadingDialog.isShowing())
        mLoadingDialog = ProgressDialog.show(this, DIALOG_TITLE, dialogMsg, true, true);
}

@Override
public void goBackground(Object... objects) {

}

@Override
public void completedRequest(Object... objects) {
    //Dismiss the dialog
    if(mLoadingDialog != null && mLoadingDialog.isShowing())
        mLoadingDialog.dismiss();

    //Parse the response based on type of request
    Integer reqCode = (Integer) objects[0];
    if(reqCode == null || reqCode == 0)
        throw  new NullPointerException("Request Code's value is Invalid.");
    switch (reqCode){
        case SEARCH_VIDEO:
            if(mYtadapter == null){
                mYtadapter = new fYtAdapter(this);
                mYtadapter.setmVideoList((List<SearchResult>)objects[1]);
                mFavLsv.setAdapter(mYtadapter);
            }else{
                mYtadapter.setmVideoList((List<SearchResult>) objects[1]);
                mYtadapter.notifyDataSetChanged();
            }
            break;
    }
}

}

I got another base adapter for another Activity and it is working fine. I can't figure out why this is not working in here. I need to display the view (with thumbnail(vidThumbnail) and title(vidTitle) in Favorites.class

*It seems that it won't got into "completedRequest" at all.

You should take a working example and build upon it. People are reluctant of doing code reviews here. — Alex.F, May 19 '15 at 07:00
@Alex.F I have a working example, and they are pretty much the same. — JustAQuestion, May 19 '15 at 07:05
@Blackbelt I didn't, I figured it out already . I just have one question. Is it possible to compare Video ID that I have to a Video ID from a result I get? — JustAQuestion, May 19 '15 at 08:31
if you didn't then you are not calling `setAdapter` and yes it is possible — Blackbelt, May 19 '15 at 08:33
@Blackbelt how can I do it? It adds me everything with the title im searching for. — JustAQuestion, May 19 '15 at 08:39

I faced this same issue. And I got the solution from here.. Link

Solution:

The only reasons getView() is not called are:

1) getCount() returns 0

2) You forget to call setListAdapter on the ListView.

3) If the ListView's visibility (or its container's visibility) is GONE.

Please see the getCout(). If it is return zero getView() will not called. And post your XML also. – Vijay May 19 '15 at 07:13
Check this `(List)objects[1])`. Here this list have values or not. – Vijay May 19 '15 at 07:20

Initialize your adapter and then set it to your ListView inside your initializeViews() method using mFavLsv.setAdapter(youradapter);

you have to add one more line -

mFavLsv.setAdapter(mYtadapter );

You missed set adapter in listview.
