Question

我使用教程中的代码将所谓的驻留菜单嵌入到我的Android Studio项目中。代码结构良好，但我无法找到正确的行，其中定义了用于打开和关闭菜单的滑动手势。该项目包含一些菜单文件。我想要做的就是减少你可以滑动以打开菜单的区域，这样当我在屏幕上的任何地方滑动时它都不会打开。

此外，也许您也可以了解我如何完全禁用操作栏（顶部栏）和某些片段上的菜单。我也找不到办法。

我从这里得到了代码：http://androidmkab.com/2017/01/28/android-reside-menu-navigation-menu/这是教程：https://www.youtube.com/watch?v=Iv71rcrspjM

请试试这个： - 我刚刚在dispatchTouchEvent方法中添加了两个if检查（标记为**）。

@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
        float currentActivityScaleX = ViewHelper.getScaleX(viewActivity);
        if (currentActivityScaleX == 1.0f) setScaleDirectionByRawX(ev.getRawX());

        switch (ev.getAction()) {
            case MotionEvent.ACTION_DOWN:
                lastActionDownX = ev.getX();
                lastActionDownY = ev.getY();
                isInIgnoredView = isInIgnoredView(ev) && !isOpened();
                pressedState = PRESSED_DOWN;
                break;

            case MotionEvent.ACTION_MOVE:
                **if (lastActionDownX > getScreenWidth() / 2) {
                    break
                }**
                if (isInIgnoredView || isInDisableDirection(scaleDirection)) break;

                if (pressedState != PRESSED_DOWN && pressedState != PRESSED_MOVE_HORIZONTAL) break;

                int xOffset = (int) (ev.getX() - lastActionDownX);
                int yOffset = (int) (ev.getY() - lastActionDownY);

                if (pressedState == PRESSED_DOWN) {
                    if (yOffset > 25 || yOffset < -25) {
                        pressedState = PRESSED_MOVE_VERTICAL;
                        break;
                    }
                    if (xOffset < -50 || xOffset > 50) {
                        pressedState = PRESSED_MOVE_HORIZONTAL;
                        ev.setAction(MotionEvent.ACTION_CANCEL);

                        if (currentActivityScaleX < 0.95) showScrollViewMenu(scrollViewMenu);

                        float targetScale = getTargetScale(ev.getRawX());
                        if (mUse3D) {
