Question

我是android的新手......我想在我的android项目中使用自定义字体，所以我把我的代码base on this tutorials。我想在R.id.Headline中使用我的自定义字体和一些xml元素

我的问题是：

- 我的代码中有什么问题吗？

- 是否有任何教程可以从xml构建自定义UI？

这是我的代码

            } catch (ExecutionException e) {

                e.printStackTrace();
            }

        }


        public View getView(int position, View convertView, ViewGroup parent) {
            View rowView = convertView;
             if (rowView == null) {
                  LayoutInflater inflater = context.getLayoutInflater();
                  rowView = inflater.inflate(R.layout.list_item, null);
                  ViewHolder viewHolder = new ViewHolder();
                  viewHolder.text = (TextView) rowView.findViewById(R.id.TextView01);
                  viewHolder.image = (ImageView) rowView
                      .findViewById(R.id.ImageView01);
                  rowView.setTag(viewHolder);
                }
            return rowView;
        }
    }

Answer 1

几个星期前我遇到了同样的问题。我认为在这个“createFromAsset”方法中使用目录是不可能的。将您的字体文件复制到父资产目录中。

Typeface myTypeface = Typeface.createFromAsset(getAssets(), "myFont.ttf");

你的logcat说什么？

Answer 2

您的代码没问题。我也以同样的方式使用自定义字体。为：

Typeface typeFace = Typeface.createFromAsset(getAssets(),"fonts/LCALLIG.TTF");          
textView.setTypeface(typeFace);

只需检查字体名称是否正确，是否正确复制到资产文件夹中如果是，则显示您的错误或logcat。

在简单适配器上使用自定义字体获取错误，错误是什么？
