为什么数字约束在LWUIT中的虚拟键盘上不起作用？ [英] Why numeric constraint didn't work on Virtual keyboard in LWUIT?

问题描述

我已经测试了很多方法来在TextField中提供数字和密码约束。但它不起作用，请参阅下面的代码。

I have tested many ways to give the numeric and password constraint in the TextField. But its not working, See the below code.

textField.setConstraint(TextField.NUMERIC | TextField.PASSWORD);
textField.setInputModeOrder(new String[]{"123"});

以上代码适用于非触控手机。但它不适用于触控手机。所以我设置了 VKB 的输入模式值，并将 TextField 与 VKB绑定，请参阅此代码。

Above code should work on the non touch mobiles. But its not working on the touch mobiles. So i have set the input mode value for VKB and bind that TextField with VKB, see this code.

TextField txt = new TextField(); 
txt.setConstraint(TextField.NUMERIC |TextField.PASSWORD); 
txt.setInputModeOrder(new String[]{"123"});
VirtualKeyboard vkb = new VirtualKeyboard(); 
vkb.setInputModeOrder(new String[]{VirtualKeyboard.NUMBERS_MODE});  
VirtualKeyboard.bindVirtualKeyboard(txt, vkb);

VirtualKeyboard.NUMBERS_MODE 我使用时无法正常工作上面的代码。 VKB 显示通常的格式。这意味着 AlphaNumeric 格式。为什么会出现这样的情况？

VirtualKeyboard.NUMBERS_MODE not working when I use above code. VKB showing as usual format. That means AlphaNumeric format. Why its showing like this?

推荐答案

这是LWUIT的一个错误，感谢你引起我们的注意我会尝试在接下来的几周内为它做出修复。它会更快但我们需要很快飞到JavaOne。

This is a bug in LWUIT, thanks for bringing it to our attention I'll try to commit a fix for it in the next couple of weeks. It would be sooner but we need to fly to JavaOne soon.

如果你想在本地尝试修复，只需在VirtualKeyboard.java中更新此方法：

If you want to try the fix locally just update this method in VirtualKeyboard.java:

public void setInputType(int inputType) {
    if((inputType & TextArea.NUMERIC) == TextArea.NUMERIC || 
            (inputType & TextArea.PHONENUMBER) == TextArea.PHONENUMBER) {
        setInputModeOrder(new String []{NUMBERS_MODE});
        return;
    }
    if((inputType & TextArea.DECIMAL) == TextArea.NUMERIC) {
        setInputModeOrder(new String []{NUMBERS_SYMBOLS_MODE});
        return;
    }
    setInputModeOrder(defaultInputModeOrder);
}
