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)：

有谁知道解决这个问题？下面是logcat：

从这里采取：source

Android OS的这个错误可能是您遇到问题的原因：

Typeface.createFromAsset泄漏资产流

此错误报告中的解决方法也在哪里：

这里有一个解决方法，因此该方法不会采用字体路径或格式。必须将字体资源的完整路径作为参数提交。我还在try-catch块中包含对createFromAsset（）的调用，以便在找不到资产时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");

我的文件位于assets / fonts / blanch_caps.ttf。

如何将字体设置为片段中的textview？
