我一直计划制作一个字体更换器应用程序，最终放在我的手机上。但是我现在遇到了一些困难，因为有些字体不起作用。我认为它实际上可能是我的代码。我可能会遗漏一些东西，因为我看到了另一个字体更换器代码并且它工作得很好。所以我想知道的是为什么这些字体中的一些不起作用。是否有某种方法我打算打电话？我对此做了一些研究，发现我必须使用import java.awt.Font;这使某些字体起作用。我可以添加自定义字体（我将在稍后），但我希望我的电脑上可用的所有字体都可以在这个应用程序中工作。
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();
}
}
/**

public void paint (Graphics g){

//g.setFont(TestTxt.setFont(new Font(item, Font.PLAIN, 12)));
