欲一个字体添加到这个 “TextView的” holder.txtName =（TextView的）view.findViewById（R.id.txtSongName）;

我试过，但它不为我工作：

// give the font path 
     String fontPath = "font/myfont.otf"; 
     TextView txtName = (TextView) findViewById(R.id.txtSongName); 
     // get the font face 
     Typeface tf = Typeface.createFromAsset((AssetManager) getAssets(), fontPath); 
     // Apply the font 
     txtName.setTypeface(tf); 
     // holder = (ViewHolder) view.getTag();

，并非常感谢你:)

您是否收到任何错误？ –

这是我怎么添加AA自定义字体，请检查你是怎么错过

1.创建资产文件夹

添加字体的单独的文件夹/目录，并将其命名为字体

3.添加字体到该文件夹

4.Now我可以把我的字体，这是我要做的事

Typeface myTypeface = Typeface.createFromAsset(getAssets(), "fonts/Xcelsion.ttf"); // if you are inside a fragment use -> getActivity().getAssets() .....check your path is correct 
    TextView myTextView = (TextView)findViewById(R.id.text_view); 
    myTextView.setTypeface(myTypeface); // set that font to the textview you want

注：如果您在接受其他类的应用工作的环境中使用yourContextThatYouGot.getAssets()，如果你是在一个片段使用getActivity().getAssets()代替getAssets()

谢谢你的回答，我将在这里使用的上下文“if（convertView == null）{LayoutInflater li =（LayoutInflater）context.getSystemService（Context.LAYOUT_INFLATER_SERVICE）; view = li.inflate（R.layout.listelement ，null）; finalHolder holder = new ViewHolder（）; holder.txtName =（TextView）view.findViewById（R.id.txtSongName）; holder.btnFavorite =（ImageView）view.findViewById（R.id.btnFavorite ）; holder.btnPlayPause =（ImageView的）view.findViewById（R.id.btnPlayPause）; view.setTag（持有人）; }其他{} 看到 –

'ListRingtonesAdapter'你从哪里打电话这一点，你怎么称呼它有它的参数'上下文'保持全局上下文mCon文本，并在其内部调用'this.mContext = context'时将其分配给'ListRingtonesAdapter'，然后获得可以使用mContext .getAssets（）的值mContext。 –
