FullScreenMode에서 키보드 활성 시 버튼 위치 변경 - SOFT_INPUT_ADJUST_RESIZE

FullScreenMode에서 SoftKeyboard 활성 시 버튼의 위치를  키패드 위로 변경하고 싶은데 일반적인 방법으로는 지원되지 않음.

기본적인 방법으로는 

1. Manifest 에서 activity 안에 

   android:windowSoftInputMode="stateHidden|adjustResize" (또는 adjustPan)

2. 자바 코드에서

   getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN);

   SOFT_INPUT_ADJUST_PAN (Input영역 밀어 올리기)

   SOFT_INPUT_ADJUST_RESIZE (UI 리사이징)

위 방법으로 해 봤지만 적용되지 않아 검색해 본 결과

안드로이드 자체에서 FullScreenMode일 때에는 지원하지 않는 것으로 보임

별도의 클래스를 만들어 간단히 해결하는 방법을 찾아 냄.

public class AndroidBug5497Workaround {
    // For more information, see https://code.google.com/p/android/issues/detail?id=5497
    // To use this class, simply invoke assistActivity() on an Activity that already has its content view set.
 
    public static void assistActivity (Activity activity) {
        new AndroidBug5497Workaround(activity);
    }    
 
    private View mChildOfContent;    
    private int usableHeightPrevious;
    private FrameLayout.LayoutParams frameLayoutParams;
 
    private AndroidBug5497Workaround(Activity activity) {
        FrameLayout content = (FrameLayout) activity.findViewById(android.R.id.content);
        mChildOfContent = content.getChildAt(0);
        mChildOfContent.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
            public void onGlobalLayout() {                
                possiblyResizeChildOfContent();
            }
        });
        frameLayoutParams = (FrameLayout.LayoutParams) mChildOfContent.getLayoutParams();
    }
 
    private void possiblyResizeChildOfContent() {
        int usableHeightNow = computeUsableHeight();
        if (usableHeightNow != usableHeightPrevious) {
            int usableHeightSansKeyboard = mChildOfContent.getRootView().getHeight();
            int heightDifference = usableHeightSansKeyboard - usableHeightNow;
            if (heightDifference > (usableHeightSansKeyboard/4)) {
                // keyboard probably just became visible
                frameLayoutParams.height = usableHeightSansKeyboard - heightDifference;
            } else {
                // keyboard probably just became hidden
                frameLayoutParams.height = usableHeightSansKeyboard;
            }
            mChildOfContent.requestLayout();
            usableHeightPrevious = usableHeightNow;
        }
    }
 
    private int computeUsableHeight() {
        Rect r = new Rect();
        mChildOfContent.getWindowVisibleDisplayFrame(r);
        return (r.bottom - r.top);
    }
}

적용할 클래스에

    AndroidBug5497Workaround.assistActivity(this);

 

넣으면 간단히 해결!!!
