Android：onConfigurationChanged()没有调用Orientation中的更改

请帮我解决这个问题.我试过但找不到原因.

码：

@Override
public void onConfigurationChanged(Configuration configurE){
    super.onConfigurationChanged(configurE);
    setLayout(); //Set the layout.

    //Get the orientation of the device and set the gravity according to that.
    if(configure.orientation == Configuration.oRIENTATION_PORTraiT) {
        parentLinearLayout.setGravity(Gravity.CENTER_VERTICAL);
    } else if(configure.orientation == Configuration.oRIENTATION_LANDSCAPE) {
        parentLinearLayout.setGravity(Gravity.CENTER_HORIZONTAL);
    }
}

<activity android:name=".AddProductsActivity" 
    android:configChanges="orientation|keyboardHidden"/>

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="15" />
