									/**监听软键盘状态

									   * @param activity

									   * @param listener

									   */

									  public static void addOnSoftKeyBoardVisibleListener(Activity activity, final OnSoftKeyBoardVisibleListener listener) {

									    final View decorView = activity.getWindow().getDecorView();

									    decorView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {

									      @Override

									      public void onGlobalLayout() {

									        Rect rect = new Rect();

									        decorView.getWindowVisibleDisplayFrame(rect);

									        int displayHight = rect.bottom - rect.top;

									        int hight = decorView.getHeight();

									        boolean visible = (double) displayHight / hight < 0.8;

									        Log.d(TAG, "DecorView display hight = " + displayHight);

									        Log.d(TAG, "DecorView hight = " + hight);

									        Log.d(TAG, "softkeyboard visible = " + visible);

									        if(visible != sLastVisiable){

									          listener.onSoftKeyBoardVisible(visible);

									        }

									        sLastVisiable = visible;

									      }

									    });

									  }
