Android – 自定义字体崩溃应用

Question

我正在尝试将 TextView 的字体更改为自定义字体。已阅读this other question 并尝试过说明as outlined here。有问题的字体是 Roboto Thin，直接从 Android Design 下载，在 ttf 中。

主活动类的代码如下：

TextView txt  = (TextView) findViewById(R.id.hometext);                  
Typeface font = Typeface.createFromAsset(getAssets(), "Roboto-Thin.ttf");       
txt.setTypeface(font);

// "hometext" is the TextView I wish to change font of.

当上面 3 行被注释时，应用程序不会崩溃，我希望这能隔离问题。

其他信息：

• Android 4.1.2 (API 16)
• 在 Android 4.4 上测试

编辑：

也试过“fonts/Roboto-Thin.ttf”和“assets/fonts/Roboto-Thin.ttf”，都不起作用。

好的，android 中有一个错误！这应该可行！

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);
            }
        }
    }

现在只需拨打Typefaces.get(this,"address of font here") 我来自here. 祝你好运！

Answer 2

看看你的字体在哪里。如果它在资产/字体中，那么字体的代码应该是：

Typeface.createFromAsset(getAssets(), "fonts/Roboto-Thin.ttf");

Answer 3

您应该先搜索相关问题，因为它说无法制作TypeFace。你给出了正确的路径吗？如果是这样，也测试其他字体。

与之前相同的问题： "Native typeface cannot be made" only for some people

另外，请使用适用于 Android 的 Fontify 库。它让一切变得更轻松、更好！
