本文整理了Java中java.awt.event.KeyEvent.<init>()方法的一些代码示例，展示了KeyEvent.<init>()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。KeyEvent.<init>()方法的具体详情如下：
包路径：java.awt.event.KeyEvent
类名称：KeyEvent
方法名：<init>

KeyEvent.<init>介绍

[英]Constructs a KeyEvent object.

Note that passing in an invalid id results in unspecified behavior.
[中]构造一个KeyEvent对象。
请注意，传入无效的id会导致未指定的行为。

代码示例

Gallery gallery = ((Gallery) findViewById(R.id.gallery));

gallery.onKeyDown(KeyEvent.KEYCODE_DPAD_LEFT, new KeyEvent(0, 0));

@NotNull
private KeyEvent createKeyEvent(@NotNull KeyStroke stroke, Component component) {

           stroke.getKeyChar() == KeyEvent.CHAR_UNDEFINED ? KeyEvent.KEY_PRESSED : KeyEvent.KEY_TYPED,
           System.currentTimeMillis(), stroke.getModifiers(), stroke.getKeyCode(), stroke.getKeyChar());
}

  final int codePoint = keyCode - KeyEvent.VK_A + 1;
  if (codePoint > 0) {
   c = Character.toChars(codePoint)[0];
  }
 }
 KeyEvent event = new KeyEvent(this, keyChar != KeyEvent.CHAR_UNDEFINED ? KeyEvent.KEY_TYPED :
                   (stroke.isOnKeyRelease() ? KeyEvent.KEY_RELEASED : KeyEvent.KEY_PRESSED),
                (new Date()).getTime(), modifiers, keyCode, c);
 super.processKeyEvent(event);
}
