在ViewPager中禁用特定区域的滚动

public class CustomViewPager extends ViewPager {

    private boolean isScrollable = true;
    private RectF disableTouchRect;

    public CustomViewPager(Context context) {
        super(context);
    }

    public CustomViewPager(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public void setScrollable(boolean scrollable) {
        isScrollable = scrollable;
    }

    public void setDisableTouchRect(RectF rect) {
        disableTouchRect = rect;
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        if (!isScrollable) {
            return false;
        }
        return super.onTouchEvent(event);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent event) {
        if (!isScrollable) {
            return false;
        }
        if (disableTouchRect != null && event.getAction() == MotionEvent.ACTION_DOWN) {
            float x = event.getX();
            float y = event.getY();
            if (disableTouchRect.contains(x, y)) {
                return false;
            }
        }
        return super.onInterceptTouchEvent(event);
    }
