修复安卓editbox被遮住问题

原因：未计算底部状态栏，导致排版上移高度不对。
处理方案：直接监听GlobalLayout,获得IME的高度，自己进行上移操作。

private void registCustomLayout() {
    layoutListener = new ViewTreeObserver.OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {
            View focus = mActivity.getCurrentFocus();
            //edit失去焦点，下移界面
            if(!(focus instanceof Cocos2dxEditBox)){
                if(isCustomLayout) mActivity.getResizeLayout().scrollTo(0,0);
                Log.d("Cocos2dxEditBox", "hideLayout "+isCustomLayout);
                isCustomLayout = false;//重置
                return;
            }

            Rect r = new Rect();
            getWindowVisibleDisplayFrame(r);
            int screenHeight = getRootView().getHeight();
            int imeHeight = screenHeight - (r.bottom - r.top);
            if(isCustomLayout && imeHeight <=0){
                mActivity.getGLSurfaceView().requestFocus();
                Log.d("Cocos2dxEditBox", "requestFocus");
                return;
            }

            //获得焦点，判断是否需要进行自定义排版
            if(!isCustomLayout){
                Cocos2dxEditBox editbox = (Cocos2dxEditBox)focus;
                FrameLayout.LayoutParams editBoxParams = (FrameLayout.LayoutParams)editbox.getLayoutParams();
                int bottomHeight = screenHeight - editBoxParams.topMargin - editBoxParams.height; //editbox底部到屏幕底部的高度
                
                if(bottomHeight >=0 && imeHeight > bottomHeight){
                    isCustomLayout = true; //不需要再次排版
                    ResizeLayout layout = mActivity.getResizeLayout();
                    int upOffset = imeHeight - bottomHeight;//界面上移高度
                    layout.scrollTo(0,upOffset);
                }
                Log.d("Cocos2dxEditBox", "isCustomLayout "+isCustomLayout);
            }
        }
    };
    getViewTreeObserver().addOnGlobalLayoutListener(layoutListener);
}

在editbox移除时取消监听

        public void onRemove(){
    if(layoutListener != null){
        getViewTreeObserver().removeOnGlobalLayoutListener(layoutListener);
    }
}
