请对 public final void closePanel(PanelFeatureState st, boolean doCallback)

方法 

在 

if (mPreparedPanel == st) {

             mPreparedPanel = null;

             mPanelChordingKey = 0;

         }

后增加clearMenuViews(st); 修改如下

if (mPreparedPanel == st) {

             mPreparedPanel = null;

             mPanelChordingKey = 0;

         }

         // for RTL

                    clearMenuViews(st);
