如何将字体设置为片段中的文本视图？

Question

我想使用以下代码更改 Fragment 中的 TextView 字体：

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle     savedInstanceState) {
   View v = inflater.inflate(R.layout.fragment_layout, container, false);
   TextView txt = (TextView) v.findViewById(R.id.Zipcode);
   Typeface font = Typeface.createFromAsset(getActivity().getAssets(), "fonts/customfont.ttf");
   txt.setTypeface(font); 
   return v;
}

但它强制关闭此声明txt.setTypeface(font)：

有人知道解决这个问题吗？下面是logcat：

Android 操作系统的这个错误可能是您的问题的原因：

Typeface.createFromAsset 泄露资产流

此错误报告中还有哪些解决方法：

这里有一个解决方法，以便该方法不采用字体路径或格式。字体资源的完整路径必须作为参数提交。我还将对 createFromAsset() 的调用封装在一个 try-catch 块中，这样如果未找到资产，get() 方法将返回 null。

public class Typefaces {
private static final String TAG = "Typefaces";

 private static final Hashtable<String, Typeface> cache = new Hashtable<String, Typeface>();

 public static Typeface get(Context c, String assetPath) {
    synchronized (cache) {
        if (!cache.containsKey(assetPath)) {
            try {
                Typeface t = Typeface.createFromAsset(c.getAssets(),
                        assetPath);
                cache.put(assetPath, t);
            } catch (Exception e) {
                Log.e(TAG, "Could not get typeface '" + assetPath
                        + "' because " + e.getMessage());
                return null;
            }
        }
        return cache.get(assetPath);
    }
}
}

另外，试试这个：

Typeface phoneticFont = Typeface.createFromAsset(getAssets(),
                                         "blanch_caps.ttf");   
I changed to:

Typeface phoneticFont = Typeface.createFromAsset(getAssets(),
                                         "fonts/blanch_caps.ttf");  

我的文件在 assets/fonts/blanch_caps.ttf 中。
