  • 读取
    `
    Typeface customFont = Typeface.createFromAsset(this.getAssets(), "fonts/YourCustomFont.ttf");
    `
    使用:

     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);
    }
    }
