Android - 键盘显示/隐藏时不调用 onConfigurationChanged

Question

我需要在按下隐藏键盘时检测隐藏键盘
我的源代码

<activity
    android:name="com.teamios.info.activity.MainScreenActivity"
    android:screenOrientation="landscape"
    android:theme="@style/Theme.MyScreenTranNorman"
    android:configChanges="orientation|keyboardHidden"
    android:windowSoftInputMode="stateUnchanged|adjustPan" />

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
    Toast.makeText(this, "keyboard visible", Toast.LENGTH_SHORT).show();
}

我在 samsung galaxy nexus phone android os 4.2.1 上测试，但是当键盘隐藏时 Toast 没有显示 请帮助我。

 <activity
        android:name="com.teamios.info.activity.MainScreenActivity"
        android:theme="@style/Theme.MyScreenTranNorman"
        android:configChanges="orientation|keyboardHidden"
        android:windowSoftInputMode="stateUnchanged|adjustPan" />

    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
    if (newConfig.hardKeyboardHidden == Configuration.HARDKEYBOARDHIDDEN_NO) {
        Toast.makeText(this, "keyboard visible", Toast.LENGTH_SHORT).show();
    } else if (newConfig.hardKeyboardHidden == Configuration.HARDKEYBOARDHIDDEN_YES) {
        Toast.makeText(this, "keyboard hidden", Toast.LENGTH_SHORT).show();
    }
    }

并添加

<activity android:name=".MyActivity" android:screenOrientation="landscape " > </activity>

在 list 类中。
