Android：Crouton lib和自定义字体

我在我的应用程序中使用自定义字体,所以我想要一个Crouton的自定义字体.我试过用setTextAppearance做它,它不起作用.

<?xml version="1.0" encoding="utf-8"?>
<com.ecab.ui.custom.TextViewCustomFont
    xmlns:android="http://scheR_530_11845@as.android.com/apk/res/android"
    xmlns:custom="http://scheR_530_11845@as.android.com/apk/res/com.crouton"
    android:id="@+id/crouton"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:BACkground="@drawable/ban_confirmation"
    android:gravity="center"
    android:text="TEST"
    android:textColor="@android:color/white"
    custom:typeface="gothamBold" />

在Style类中：

INFOCUSTOM = new Builder().setDuration(3000).setTextAppearance(R.id.crouton).build();

然后,我试图通过使用我的字体更改setTypeface()来实现它,它不起作用.

在Crouton班：

private TextView initializeTextView(final resources resources) {
TextView text = new TextView(this.activity);
    text.setId(TEXT_ID);
    text.setText(this.text);
    text.setTypeface(MyFonts.getGothamBookBold(this.activity));
    Log.d(Constants.D_TAG,"chaneg the typeFace");
    text.setGravity(this.style.gravity);
    // set the text color if set
    if (this.style.textColorresourcEID != 0) {
      text.setTextColor(resources.getColor(this.style.textColorresourcEID));
    }

    // Set the text size. If the user has set a text size and text
    // appearance,the text size in the text appearance
    // will override this.
    if (this.style.textSize != 0) {
      text.setTextSize(TypedValue.COMPLEX_UNIT_SP,this.style.textSizE);
    }

    // Setup the shadow if requested
    if (this.style.textShadowColorResId != 0) {
      initializeTextViewShadow(resources,text);
    }

    // Set the text appearance
    if (this.style.textAppearanceResId != 0) {
      text.setTextAppearance(this.activity,this.style.textAppearanceResId);
    }
    return text;
  }

如何拥有自定义字体？

ps：库版本==> 1.7

setTextAppearance(R.id.crouton)

INFOCUSTOM = new Builder().setDuration(3000).setBACkgroundDrawable(R.drawable.ban_confirmation).setHeight(LayoutParams.WRAP_CONTENT)
          .build();
