如何在黑莓中为editField设置onKeyEnter事件？
如何为EditField设置onKeyEnter事件。我当前的屏幕中有两个 EditField。但我必须只设置一个 EditField 事件。我该如何设置呢？我在同一屏幕中有按钮字段和列表字段。我什至可以为按钮和列表设置点击。但问题是为 EditField 设置事件。
我已经使用了 key down 和 keychar 方法。但这对我没用。 我用下面的方法检查了。
protected boolean keyChar(char key, int status, int time){
if (key == Characters.ENTER){Dialog.alert("hi");}
return false;
}
protected boolean keyChar(char character, int status, int time){
if (Characters.ENTER == character){Dialog.alert("hi");}
return false;
}
如果我这样使用，我无法在编辑字段中输入任何字符。
谁能帮助我吗？

你正在吃掉所有的击键，因为你没有返回 super.keyChar(key, status, time)。
如果您不消耗密钥，则需要将其向上传递。
You're eating all the keystrokes because you're not returning super.keyChar(key, status, time).
If you don't consume the key, you need to pass it on up.
