将不同的字体应用于android中按钮中的文本

Question

我正在创建一个用于重新加载的android按钮。它想在按钮中同时有图标和文本，所以我使用的是font真棒。但是我如何在按钮文本上同时应用我在应用程序中使用的字体和自定义字体呢。

Answer 1

这就是我实现它并使用CustomTypefaceSpan类的方式https://stackoverflow.com/a/10741161/992665

public class MainActivity extends Activity {
    Typeface tf_r, tf_icon;
    Button reload;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        int hexVal = Integer.parseInt("f021", 16);
        SpannableStringBuilder SS = new SpannableStringBuilder((char)hexVal + " Refresh");
        tf_r = Typeface.createFromAsset(this.getAssets(), "www/fonts/Roboto-Light.ttf");
        tf_icon = Typeface.createFromAsset(this.getAssets(), "www/fonts/fontawesome-webfont.ttf");
        SS.setSpan(new CustomTypefaceSpan("", tf_icon), 0, 1,Spanned.SPAN_EXCLUSIVE_INCLUSIVE);
        SS.setSpan(new CustomTypefaceSpan("", tf_r), 1, 9,Spanned.SPAN_EXCLUSIVE_INCLUSIVE);
        reload = (Button) findViewById(R.id.no_openings_reload);
        reload.setText(SS);
    }
}

Answer 2

尝试以下代码：-

String text = "This is an example";
Spannable s = new SpannableString(text + " text");
s.setSpan(new TypefaceSpan("monospace"), 0, text.length(),
            Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
s.setSpan(new TypefaceSpan("serif"), text.length(), s.length(),
            Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
((TextView)findViewById(R.id.my_text_view)).setText(s);

或

TextView myTextView=(TextView)findViewById(R.id.textBox);
Typeface typeFace=Typeface.createFromAsset(getAssets(),"fonts/mytruetypefont.ttf");
myTextView.setTypeface(typeFace);

或

Typeface tf = Typeface.createFromAsset(getAssets(),"fonts/verdana.ttf");
textfield.setTypeface(tf,Typeface.BOLD);
