Java JTextArea KeyListener

Question

当我按下 ENTER 时，我的 JTextArea 开始了一个新行，我只想对 doClick() 方法做任何其他事情。我应该怎么做？

textarea.addKeyListener(new KeyListener(){
    @Override
    public void keyPressed(KeyEvent e){
        if(e.getKeyCode() == KeyEvent.VK_ENTER){
        button.doClick();
        }
    }

    @Override
    public void keyTyped(KeyEvent e) {
    }

    @Override
    public void keyReleased(KeyEvent e) {
    }
});

Answer 1

使用.consume():

Consumes this event so that it will not be processed in the default manner by the source which originated it.

public void keyPressed(KeyEvent e){
    if(e.getKeyCode() == KeyEvent.VK_ENTER){
    e.consume();
    button.doClick();
    }
}
