java - 无法在 J2ME 字符串中插入制表符空格 ("\t")

Question

我有一个字符串

str = "Hello\tWorld";

当我在 J2ME 应用程序中打印字符串时，结果是：

"HelloWorld"代替"Hello<tab space>World"

运行以下示例代码时，文本字段不显示制表符空间，而仅显示“HelloWorld”而没有制表符空间。

示例代码：

public class MyApp extends MIDlet {

    private Display display;
    private Form frmMain;

    public MyApp() {
        display = Display.getDisplay(this);
        frmMain = new Form("Hello");
    }


    protected void startApp() throws MIDletStateChangeException {
        TextField txt = new TextField("Text", "", 200, TextField.ANY);
        txt.setString("Hello\tWorld");
        frmMain.append(txt);

        display.setCurrent(frmMain);
    }

    protected void pauseApp() {
    }

    protected void destroyApp(boolean unconditional) throws MIDletStateChangeException {
        destroyApp(unconditional);
        notifyDestroyed();
    }
}
