如何覆盖的＆lt; ENTER＆GT;虚拟键盘Android中的关键行为 [英] How to override the <ENTER> key behaviour of the virtual keyboard in Android

问题描述

我要重写的行为<大骨节病> ENTER 虚拟键盘的键，以便：

I want to override the behaviour of the ENTER key of the virtual keyboard so that:

• 当有屏幕上的更多领域，这片下一个字段
• 当它是屏幕的最后一个字段，它执行的屏幕
的默认操作

我一直在玩的IME选项和标签，但只是没有得到我想要的。任何人有什么建议？

I've been playing with the IME options and labels, but just don't get what I want. Anybody have any suggestions?

推荐答案

通过在另一个论坛的帮​​助下，我发现这样做的方式。

With help on another forum, I found the way to do it.

要使它可重复使用的，我已经创建了一个包含2 OnKeyListener 对象和抽象方法提出我自己的超级对话框类：

To make it reusable, I have created my own super dialog class that contains 2 OnKeyListener objects and an abstract submit method:

public abstract class MyAbstractDialog extends Dialog {

/**
 * OnKeyListener that puts the focus down when the ENTER key is pressed
 */
protected View.OnKeyListener onEnterFocusDown = new View.OnKeyListener() {

                @Override
                public boolean onKey(View v, int keyCode, KeyEvent event) {
                if ((event.getAction() == KeyEvent.ACTION_DOWN) &&
                            (keyCode == KeyEvent.KEYCODE_ENTER)) {
                                v.requestFocus(View.FOCUS_DOWN);
                        return true;
                }
                        return false;
                }
        };

/**
 * OnKeyListener that submits the page when the ENTER key is pressed
 */
protected View.OnKeyListener onEnterSubmitView = new View.OnKeyListener() {

                @Override
                public boolean onKey(View v, int keyCode, KeyEvent event) {
                if ((event.getAction() == KeyEvent.ACTION_DOWN) &&
                            (keyCode == KeyEvent.KEYCODE_ENTER)) {
                                submitView(v);
                        return true;
                }
                        return false;
                }
        };
        protected abstract void submitView(View v);

}

现在在对话框我可以使用这些对象在我的领域设置：

Now in the Dialog I can use these objects to set on my fields:

// make the ENTER key on passwordField1 put the focus on the next field
passwordField1.setOnKeyListener(onEnterFocusDown);

// make the ENTER key on passwordField2 submit the page
passwordField2.setOnKeyListener(onEnterSubmitView);
