使用单个项目字体滚动列表视图时更改字体

Question

我有一个带有自定义数组适配器的ListView设置我想更改每个列表项的字体，下面的getVIew()方法代码确实会更改字体但字体会随着我向上和向下滚动而改变

public View getView(int position, View convertView, ViewGroup parent){
    View v = convertView;

    //View row = null;

    if (v == null) {
        LayoutInflater inflater = Main.this.getLayoutInflater();
        v = inflater.inflate(R.layout.genre_list, parent, false);
        TextView item = (TextView)v.findViewById(R.id.txtListText);
        switch(position) {
        case 0:
            tf = Typeface.createFromAsset(getAssets(),"fonts/font (1).ttf");item.setTypeface(tf);
            break;
        case 1:
            tf = Typeface.createFromAsset(getAssets(),"fonts/font (2).ttf"); item.setTypeface(tf);
            break;
        case 2:
            tf = Typeface.createFromAsset(getAssets(),"fonts/font (3).ttf"); item.setTypeface(tf);
            break;
        case 3:
            tf = Typeface.createFromAsset(getAssets(),"fonts/font (4).ttf"); item.setTypeface(tf);
            break;
        case 4:
            tf = Typeface.createFromAsset(getAssets(),"fonts/font (5).ttf"); item.setTypeface(tf);
            break;
        case 5:
            tf = Typeface.createFromAsset(getAssets(),"fonts/font (6).ttf"); item.setTypeface(tf);
            break;
        case 6:
            tf = Typeface.createFromAsset(getAssets(),"fonts/font (7).ttf"); item.setTypeface(tf);
            break;
        case 7:
            tf = Typeface.createFromAsset(getAssets(),"fonts/font (8).ttf"); item.setTypeface(tf);
            break;
        case 8:
            tf = Typeface.createFromAsset(getAssets(),"fonts/font (9).ttf"); item.setTypeface(tf);
            break;
        case 9:
            tf = Typeface.createFromAsset(getAssets(),"fonts/font (10).ttf"); item.setTypeface(tf);
            break;
        default:
            tf = Typeface.createFromAsset(getAssets(),"fonts/font (10).ttf"); item.setTypeface(tf);
        }
    }

    TextView item = (TextView)v.findViewById(R.id.txtListText);
    item.setText(Genres[position]);     

    // Declare and define the TextView, "icon." This is where
    // the icon in each row will appear.

    return v;
}
