Android TypefaceSpan NoSuchMethoderRror for new TypefaceSpan（Typeface）

Question

int id = context.getResources.getIdentifier("xxx","font",packageName);
Typeface typeface = context.getResources.getFont(id);

TypefaceSpan span = new TypefaceSpan(typeface);

nosuchMethodError：类landroid/text/style/typefaceSpan中没有直接方法（landroid/graphics/typeface；）V；或者它的超级类（'android.text.style.TypeFaceSpan'的声明出现在/system/framework/framework.jar！classes2.dex中）。

请帮帮忙。提前道谢。

我也有同样的问题，这个答案对我有效

您需要创建CustomTypeFaceSpan类

import android.graphics.Paint;
import android.graphics.Typeface;
import android.text.TextPaint;
import android.text.style.TypefaceSpan;

public class CustomTypefaceSpan extends TypefaceSpan {

   private final Typeface newType;

   public CustomTypefaceSpan(String family, Typeface type) {
     super(family);
     newType = type;
   }

   @Override
   public void updateDrawState(TextPaint ds) {
     applyCustomTypeFace(ds, newType);
   }

   @Override
   public void updateMeasureState(TextPaint paint) {
     applyCustomTypeFace(paint, newType);
   }

   private static void applyCustomTypeFace(Paint paint, Typeface tf) {
     int oldStyle;
     Typeface old = paint.getTypeface();
     if (old == null) {
       oldStyle = 0;
     } else {
       oldStyle = old.getStyle();
     }

     int fake = oldStyle & ~tf.getStyle();
     if ((fake & Typeface.BOLD) != 0) {
       paint.setFakeBoldText(true);
     }

     if ((fake & Typeface.ITALIC) != 0) {
       paint.setTextSkewX(-0.25f);
     }

     paint.setTypeface(tf);
   }
 }

那就这样用吧

TypeFace face = ResourcesCompat.getFont(context, R.font.font_name); // in case you want to support below API 26.
new CustomTypefaceSpan("", face);
