1. java中如何修改JDialog、JLable等汉字的显示字体
boundary.setFont(new Font("TimesRoman", Font.PLAIN, 13");
如果手头有ttf字体文件还可以通过加载字体文件自定义字体，如下：
Font font = Font.createFont(Font.TRUETYPE_FONT, new File(
"src/Font/minidy.ttf"));
AWT定义的五种逻辑字体：
* SansSerif
* Serif
* Monospaced
* Dialog
* DialogInput
这些字体被映射到客户机上的实际字体如在Windows下，SansSerif被映射到Arial。
Font helvb14 = new Font("Helvetica", Font.BOLD, 14);
第二个参数是字体风格
Font.PLAIN
Font.BOLD
Font.ITALIC
Font.BOLD+Font.ITALIC
提供字体名的位置也可以给出逻辑字体的名称，如
Font sansbold14 = new Font("SansSerif", Font.BOLD, 14);
boundary.setFont(sansbold14);
如果还不懂网络hi我就好！
2. java中如何读取ttf字体文件，生成Font数组
1.读取
import java.awt.Font;
import java.io.File;
import java.io.FileInputStream;
public class Loadfont
{
public static Font loadFont(String fontFileName, float fontSize) //第一个参数是外部字体名，第二个是字体大小
{
try
{
File file = new File(fontFileName);
FileInputStream aixing = new FileInputStream(file);
Font dynamicFont = Font.createFont(Font.TRUETYPE_FONT, aixing);
Font dynamicFontPt = dynamicFont.deriveFont(fontSize);
aixing.close();
return dynamicFontPt;
}
catch(Exception e)//异常处理
{
e.printStackTrace();
return new java.awt.Font("宋体", Font.PLAIN, 14);
}
}
public static java.awt.Font Font(){
String root=System.getProperty("user.dir");//项目根目录路径
Font font = Loadfont.loadFont(root+"/data/PRISTINA.ttf", 18f);//调用
return font;//返回字体
}
public static java.awt.Font Font2(){
String root=System.getProperty("user.dir");//项目根目录路径
Font font = Loadfont.loadFont(root+"/data/XXXX.ttf", 18f);
return font;//返回字体
}
}
2.转换：
public static String ascii2native(String ascii) {
int n = ascii.length() / 6;
StringBuilder sb = new StringBuilder(n);
for (int i = 0, j = 2; i < n; i++, j += 6) {
String code = ascii.substring(j, j + 4);
char ch = (char) Integer.parseInt(code, 16);
sb.append(ch);
}
return sb.toString();
}
3. java字体设置
写图形控件，如果不指定字体，将会用JRE在操作系统环境下的默认字体。
有源码的情况下，如果去更改JRE的字体，显然不够直接也会破坏统一的环境。
通常是在源码中从显示控件比如Label或JLabel的setFont指定一个统一的字体，比如"宋体"
然后把宋体的字体文件simsun.ttf作为资源文件打在jar中.，或者放在外面作为运行时调用。
这样能统一在各平台的字体效果。
默认情况JRE只提供拉丁字母集的跨平台字体，没有包括中文。
4. java相关，关于使用itext导出pdf后，中文字体设置的问题。
可以直接调用字体 写一个
BaseFont bf=BaseFont.createFont("字体",BaseFont.CP1250, BaseFont.EMBEDDED);
字体就设置，你的那个字体路径
5. java 如何读取otf字体急求高手解答。。
import java.io.FileOutputStream;
import com.lowagie.text.Document;
import com.lowagie.text.Font;
import com.lowagie.text.Paragraph;
import com.lowagie.text.pdf.BaseFont;
import com.lowagie.text.pdf.PdfWriter;
public class MainClass {
public static void main(String[] args) throws Exception {
Document document = new Document();
PdfWriter.getInstance(document, new FileOutputStream("2.pdf"));
document.open();
BaseFont bf = BaseFont.createFont("esl_gothic_shavian.otf", "Cp1252", BaseFont.EMBEDDED);
System.err.println(bf.getClass().getName());
Font font = new Font(bf, 12);
document.add(new Paragraph("abced"));
document.add(new Paragraph("this is a test", font));
document.close();
}
}
这段程序貌似是把pdf设置成otf字体输出，改一下就好！
这程序绝对经得起考研！从国外教程网站找到d！
把esl_gothic_shavian.otf换成你的字体
6. 如何获取android系统的字体名称
在java环境中有一个专门的获取ttf文件的头信息的Font类
Font f = Font.createFont(Font.TRUETYPE_FONT, new FileInputStream("seguisym.ttf"));
String name = f.getName();
System.out.println(name);
但是在android环境下，我们无法直接用到该类去解析TTF文件，下面我将附上代码来解析ttf文件
TTFParser.Java
import java.io.IOException;
import java.io.RandomAccessFile;
import java.nio.charset.Charset;
import java.util.HashMap;
import java.util.Map;
/**
* TTF Font file parser
* <p>
* sample:
* <code><pre>
* File fs = new File("C:\\Windows\\Fonts");
* File[] files = fs.listFiles(new FilenameFilter() {
* public boolean accept(File dir, String name) {
* if (name.endsWith("ttf")){ return true;}
* return false;
* }
* });
* for (File file : files) {
* TTFParser parser = new TTFParser();
* parser.parse(file.getAbsolutePath());
* System.out.println("font name: " + parser.getFontName());
* }
* </pre></code>
