在做Android系统开发的时候，由于系统要求，字体已经固定。但是发现系统自带的浏览器，标签页标题字体太小的。不知道怎么修改。
看了一下源码，Tag.java的源码中有可以找到标题的变量mTitle，但是不知道如何修改字体的大小，希望大牛指点。
// All the state needed for a page
protected static class PageState {
String mUrl;
String mOriginalUrl;
String mTitle;
SecurityState mSecurityState;
// This is non-null only when mSecurityState is SECURITY_STATE_BAD_CERTIFICATE.
SslError mSslCertificateError;
Bitmap mFavicon;
boolean mIsBookmarkedSite;
boolean mIncognito;
PageState(Context c, boolean incognito) {
mIncognito = incognito;
if (mIncognito) {
mOriginalUrl = mUrl = "browser:incognito";
mTitle = c.getString(R.string.new_incognito_tab);
} else {
mOriginalUrl = mUrl = "";
mTitle = c.getString(R.string.new_tab);
}
mSecurityState = SecurityState.SECURITY_STATE_NOT_SECURE;
}
PageState(Context c, boolean incognito, String url, Bitmap favicon) {
mIncognito = incognito;
mOriginalUrl = mUrl = url;
if (URLUtil.isHttpsUrl(url)) {
mSecurityState = SecurityState.SECURITY_STATE_SECURE;
} else {
mSecurityState = SecurityState.SECURITY_STATE_NOT_SECURE;
}
mFavicon = favicon;
}
}
