単一の TextView 内で複数のカスタム フォントを使用する場合:
次のコードを使用します:(私はバングラとタミル語のフォントを使用しています)
TextView txt = (TextView) findViewById(R.id.custom_fonts);
txt.setTextSize(30);
Typeface font = Typeface.createFromAsset(getAssets(), "Akshar.ttf");
Typeface font2 = Typeface.createFromAsset(getAssets(), "bangla.ttf");
SpannableStringBuilder SS = new SpannableStringBuilder("আমারநல்வரவு");
SS.setSpan (new CustomTypefaceSpan("", font2), 0, 4,Spanned.SPAN_EXCLUSIVE_INCLUSIVE);
SS.setSpan (new CustomTypefaceSpan("", font), 4, 11,Spanned.SPAN_EXCLUSIVE_INCLUSIVE);
txt.setText(SS);
結果は次のとおりです。
CustomTypefaceSpan クラス:
package my.app;
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);
}
}
