Slow transition of activity: multiple "initial state of inflation" in LogCat

To create a custom font in mine ListActivity, I wrote a class CustomAdapterextending BaseAdapteraccording to this example here .

However, as described there, I wrote a method getView()as shown below:

public View getView(int position, View convertView, ViewGroup parent){
    String gameName = gameNames[position]; // gameName ist the String[] of the Custom Adapter

    TextView tv = new TextView(context);
    tv.setText(gameName);
    tv.setTypeface(Typeface.createFromAsset(context.getAssets(), "fonts/gulim.ttf"));

    return tv;
}

It works as intended. The only thing that bothers is that it takes about three or four seconds until a list appears (and this is a very long time in this context). However, in ListActivityI installed onItemClickListeneras follows:

private void setOnItemClickListener(){
    getListView().setOnItemClickListener(new OnItemClickListener() {
        public void onItemClick(AdapterView<?> parent, View view, int pos, long id){
            onClickEntryButton(((TextView) view).getText().toString());
        }
    });
}

private void onClickEntryButton(String gameName){
    Intent intent = new Intent(this, GameActivity.class);
    intent.putExtra("gameName", gameName);
    startActivity(intent);
    finish();
}
