Answer 1

[android-developers] Re: Detect Physical Keyboard Layout (ex: QWERTY vs QWERTZ)

The flags provided by getResources().getConfiguration().keyboard are a good way of checking which keyboard (if any) is available.

Answer 2

Use the following method to ascertain presence of hard keyboard at any time:
(To my knowledge, soft keyboards all lack the features tested below )

public static boolean isHardKB(Context ctx) {
    Configuration cf = ctx.getResources().getConfiguration();
    return cf.navigation==Configuration.NAVIGATION_DPAD
        || cf.navigation==Configuration.NAVIGATION_TRACKBALL
        || cf.navigation==Configuration.NAVIGATION_WHEEL;
}

通过AndroidManifest,对每个受影响活动进行实时的关键改变:

android:configChanges="keyboard|keyboardHidden|navigation"

但是,可以肯定地支持上述明显变化,(至少是)一种 du:onConfigurationChanged()。

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
    // Optionally employ  isHardKB()    
}

Answer 3

检测共同的下水道关键板的连接使用:

private boolean isKeyboardConnected() {
    return getResources().getConfiguration().keyboard == KEYBOARD_QWERTY;
}
