从物理键盘切换到软件键盘.大家好，我正在开发一个将在装有 Android 3.2 的平板电脑上运行的应用程序.我将物理键盘连接到平板电脑，然后软件键盘消失了.现在我需要在某些活动中使用软件键盘，但我不知道如何做到这一点.

Switch from physical to software keyboard. Hi all, I'm developing an application that will run on a tablet with Android 3.2. I attached a physical keyboard to tablet then the software keyboard disappear. Now I need to use the software keyboard in some activities, but I don't figure out how I can do that.

我尝试了不同的方法:

Android:自动显示软键盘焦点在 EditText

如果连接了物理键盘，所有这些都不起作用.

All these don't work if the physical keyboard is connected.

有人知道我怎样才能实现这个目标吗?

Someone know how can I achieve this goal?

谢谢

推荐答案

设置下会有语言和输入法">>键盘设置>>输入法选择器">>始终显示"

Under setting ther will be "Language & Input" >> Keyboard Setting >> "Input method selector" >> "Always show"

插入键盘后，只需将键盘图标放在屏幕右下角"，选择使用物理键盘"即可关闭

after you plug in the keyboard just put on the Keyboard ICON "on the bottom right of the screen" the select "USE PHYSICAL KEYBOARD" to off

然后软键盘(屏幕上)将正常显示，直到您拔下键盘.

Then the Soft keyboard (on screen) will appear normally until you unplug the keyboard.

在我的情况下，我使用条形码扫描仪而不是键盘，所以我确实需要一些软键盘，但是我使用 USB 集线器并连接条形码扫描仪和数字键盘.

In my case i use the barcode scanner instead of keyboard so I do need some softkeyboard however I use the USB hub and connect both barcode scanner and numeric keyboard.

希望这会对你有所帮助.

hope this will help you.
