Question

我有一个帮助方法，可以执行以下操作：

public CustomTypefaceSpan(Context context, String typefaceName) {
    mTypeface = sTypefaceCache.get(typefaceName);

    if (mTypeface == null) {
        mTypeface = Typeface.createFromAsset(context.getApplicationContext().getAssets(),
                String.format("fonts/%s", typefaceName));

        // Cache the loaded Typeface
        sTypefaceCache.put(typefaceName, mTypeface);
    }
}

切换到可下载字体后，我们得到以下异常，因为assets文件夹中没有可用的字体。我们怎样才能用可下载的字体执行此操作？谢谢！

以下示例代码说明了整个可下载字体过程：

 FontRequest request = new FontRequest("com.example.fontprovider.authority",
            "com.example.fontprovider", "my font", certs); 
    FontsContract.FontRequestCallback callback =
        new FontsContract.FontRequestCallback() { 
            @Override 
            public void onTypefaceRetrieved(Typeface typeface) {
                // Your code to use the font goes here 
                ... 
            } 

            @Override 
            public void onTypefaceRequestFailed(int reason) {
                // Your code to deal with the failure goes here 
                ... 
            } 
    }; 
FontsContract.requestFonts(context, request, callback , handler);

我们如何从可下载的字体创建字体？
