问题描述
谁能告诉我是否有任何方法可以找出蓝牙 QWERTY 键盘是否连接到 android 设备.
我尝试使用 getResources().getConfiguration.keyboard,但无论是否连接键盘,它总是给我相同的值.
谢谢
实现此目的的一种方法是将 android:configChanges="keyboard"
添加到 AndroidManifest.xml 文件中的活动中.p>
有了这个,你可以覆盖 onConfigurationChanged
每当插入或拔出键盘时都会调用它
@Override公共无效 onConfigurationChanged(配置新配置){如果(newConfig.hardKeyboardHidden == Configuration.HARDKEYBOARDHIDDEN_NO){//正在连接一个硬件键盘}否则如果(newConfig.hardKeyboardHidden == Configuration.HARDKEYBOARDHIDDEN_YES)//一个硬件键盘正在断开连接}}
Can anyone please tell me if there is any way we can find out if a bluetooth QWERTY keyboard is attached to android device.
I tried working with getResources().getConfiguration.keyboard, but it always gives me the same value whether key board is attached or not.
Thanks
One way to do this is adding android:configChanges="keyboard"
to the activity in your AndroidManifest.xml file.
With this you can override onConfigurationChanged
which will be called whenever a keyboard is plugged in or plugged out
@Override
public void onConfigurationChanged(Configuration newConfig)
{
if(newConfig.hardKeyboardHidden == Configuration.HARDKEYBOARDHIDDEN_NO) {
//A hardware keyboard is being connected
}
else if(newConfig.hardKeyboardHidden == Configuration.HARDKEYBOARDHIDDEN_YES)
//A hardware keyboard is being disconnected
}
}
