软键盘(挡住button,和点击外部软键盘消失)

以下是解决挡住button的逻辑 (写的比较急,黄色的部分就是edittext)

//    控制是否移动布局。比如只有密码输入框获取到焦点时才执行。public  boolean flag = true;/** * @param act          activiry用于获取底部导航栏高度。 * @param root         最外层布局，需要调整的布局 * @param scrollToView 被键盘遮挡的scrollToView，滚动root,使scrollToView在root可视区域的底部 */public  void controlKeyboardLayout(Context act, final View root, final View scrollToView) {    final int navigationBarHeight = getNavigationBarHeight(act);    root.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {        @Override        public void onGlobalLayout() {            Rect rect = new Rect();            //获取root在窗体的可视区域            root.getWindowVisibleDisplayFrame(rect);            //获取root在窗体的不可视区域高度(被其他View遮挡的区域高度)            int rootInvisibleHeight = root.getRootView().getHeight() - rect.bottom;            //若不可视区域高度大于100，则键盘显示            if (rootInvisibleHeight > navigationBarHeight && flag) {                int[] location = new int[2];                //获取scrollToView在窗体的坐标                scrollToView.getLocationInWindow(location);                //计算root滚动高度，使scrollToView在可见区域                int srollHeight = (location[1] + scrollToView.getHeight()) - rect.bottom;                if (root.getScrollY() != 0) {// 如果已经滚动，要根据上次滚动，重新计算位置。                    srollHeight += root.getScrollY();                }                root.scrollTo(0, srollHeight);            } else {                //键盘隐藏                root.scrollTo(0, 0);            }        }    });}

以下是解决控制点击可选择的区域让软键盘消失或者不消失
