我一直在计划制作一个字体转换器应用程序，最终放在我的手机上。但我现在遇到了一些困难，因为有些字体不起作用。我认为这实际上可能是我的代码。我可能遗漏了一些东西，因为我看到了另一个字体更改器代码并且它运行良好。所以我只想知道为什么其中一些字体不起作用。我应该调用某种方法吗？我对此做了一些研究，发现我必须使用 import java.awt.Font; 这使得某些字体起作用。我可以添加自定义字体（稍后会添加），但我希望我的电脑上的所有字体都可以在这个应用程序中使用。

这是我的代码：

import java.awt.*;
import java.awt.Font.*;
import java.awt.event.*;
import java.applet.Applet;

public class FontChangerForAndroid extends Applet implements ActionListener
    {

    Button Change;
    Button TestOutput;
    Choice Fonts;
    TextField TestTxt;
    Label text;
    /***
     * Okay, this works so far. Not sure if the comic one isnt working. Or if I just spelled it wrong. I will have to
     * look it up in a java Font libaray.
     *
     * I basically want to make this a function on my entire phone. So i'll have to change it to an android app.
     * ( I hope it has the Rosemarry font)
     * While I'm practicing with this app, I'll add a text box that will let me change the label. Or enter the words
     * in the app.
     *
     */
    public void init(){

        setLayout(new FlowLayout());
        Fonts = new Choice();
        //Some fonts don't work because we I don't know what fonts are in the JGE. Working on how to find them
        //Will just add fonts to this system if possible.
        Fonts.addItem("Dialog");
        Fonts.addItem("Serif");
        Fonts.addItem("SansSerif");
        Fonts.addItem("Monospaced");
        Fonts.addItem("DialogInput");
        Fonts.addItem("Calist");
        Fonts.addItem("Centbi");

        add(Fonts);
        TestTxt = new TextField("Enter Text",15);
        add(TestTxt);
        TestOutput = new Button("Enter");
        add(TestOutput);
        Change = new Button("Change Font");
        add(Change);
        text = new Label("Real eye realize real lies");
        add(text);

        Change.addActionListener(this);
        TestOutput.addActionListener(this);
    }

   public void actionPerformed(ActionEvent evt) {
      String item = (String) Fonts.getSelectedItem(); 
      //Gets the selected option from the list and sets the text as the Font.
      if (evt.getSource() == Change){
        text.setFont(new Font(item, Font.PLAIN, 12));
      }
      //In this section you can enter something and print it out on the screen.
      if ( evt.getSource() == TestOutput){
         repaint();
       }
    }


    /**
     * I'm trying to figure out what code goes here in order for the font to change here also....5/22/13
     *
     */
    public void paint (Graphics g){
     //String item = Fonts.getSelectedItem();
    //g.setFont(TestTxt.setFont(new Font(item, Font.PLAIN, 12)));  
     g.drawString(TestTxt.getText(),20,100);

    }
}

有一个方法GraphicsEnvironment被调用registerFont。EG 如this answer所示。
