我正在尝试使TypefaceSpan TypefaceSpan on developer.android.com
该页面上提供的示例使用新的TypefaceSpan(Typeface)似乎现在是错误的,因为没有这样的构造函数。因此,我尝试使用新的TypefaceSpan(Parcel)时没有运气(我不知道如何正确地将Typeface放入Parcel),而新的TypefaceSpan(String)仅支持系统字体(我无法使其与自定义字体一起使用) 。
有谁知道,如何将TypefaceSpan与自定义字体一起使用(来自res / font)?
最佳答案
希望这对您有用。
像这样声明变量:
Typeface typeface;
像这样初始化变量:
typeface = Typeface.createFromAsset(getAssets(), "fonts/yourFontName.ttf");
设置为这样的视图:
yourView.setTypeface(typeface);
上面的代码用于将字体设置为视图。
对于CustomTypeFaceSpan,将以下类添加到您的包中。
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);
}
}
像这样使用上面的类:
Typeface typeface = Typeface.createFromAsset(getAssets(), "fonts/YourFontName.ttf");
SpannableString mNewTitle = new SpannableString("Your String Value");
mNewTitle.setSpan(new CustomTypefaceSpan("", typeface), 0, mNewTitle.length(), Spannable.SPAN_INCLUSIVE_INCLUSIVE);
yourView.setText(mNewTitle);
