Question

我有这个绑定适配器：

private static final String TAG = Bindings.class.getSimpleName();
private static Map<String, Typeface> typefaceCache = new HashMap<>();

@BindingAdapter({"font"})
public static void setFont(View view, String fontPath) {
    Log.d(TAG, "setFont() called with: " + "view = [" + view + "], fontPath = [" + fontPath + "]");
    if (view instanceof EditText) {
        ((EditText) view).setTypeface(getTypeface(view.getContext(), fontPath));
    } else if (view instanceof TextView) {
        ((TextView) view).setTypeface(getTypeface(view.getContext(), fontPath));
    } else if (view instanceof TextInputLayout) {
        ((TextInputLayout) view).setTypeface(getTypeface(view.getContext(), fontPath));
    } else if (view instanceof ViewGroup) {
        for (int i = 0; i < ((ViewGroup) view).getChildCount(); i++)
            setFont(((ViewGroup) view).getChildAt(i), fontPath);
    }
}

public static Typeface getTypeface(Context ctx, String fontPath) {
    Log.d(TAG, "getTypeface() called with: " + "ctx = [" + ctx + "], fontPath = [" + fontPath + "]");
    AssetManager assetManager = ctx.getAssets();
    Typeface typeface = typefaceCache.get(fontPath);
    if (typeface == null) {
        typeface = Typeface.createFromAsset(assetManager, fontPath);
        typefaceCache.put(fontPath, typeface);
    }
    return typeface;
}

通过数据绑定，我在布局中调用font属性，如下所示：

app:font="@{Helper.BRANDON_GROTESQUE_MEDIUM}"

我正确的字体是：

public static final String BRANDON_GROTESQUE_MEDIUM = "fonts/BrandonGrotesque-Medium.otf";

还有一些日志：

06-07 18:45:55.627 2883-2883 / D / Bindings：setFont（）调用：view = [android.support.v7.widget.AppCompatTextView {96d0a86 V.ED ....... ... ID 327,233-408,290＃7f0c010e app：id / tv_value_units_5}]，fontPath = [fonts / BrandonGrotesque-Medium.otf]

06-07 18:45:55.627 2883-2883 / D / Bindings：getTypeface（）调用：ctx = [android.support.v7.widget.TintContextWrapper@ca3b6fc]，fontPath = [fonts / BrandonGrotesque-Medium。 OTF]

我得到一些Typeface对象返回：

typeface = [android.graphics.Typeface@73109992]

我没有收到任何错误，但文字字体没有变化，我似乎无法找到我做错了什么。请帮助：）

更多信息：在应用程序的先前版本中，我让代码正常工作，在onCreate中设置字体。所以它实际上正在工作，Typeface的加载方式与现在的Typeface.createFromAsset相同......

现在我正在调试器中看到正在调用TextView.setTypeface。此时mLayout为空。

@Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        binding = DataBindingUtil.inflate(inflater, R.layout.fragment_plugs, container, false);

        choosePlugsViewModel();

        return binding.getRoot();
    }

字体绑定适配器无法正常工作
