将SlidingPaneLayout的触摸事件限制在屏幕的最左边

Question

是否可以将SlidingPaneLayout的触摸事件限制在DrawerLayout中发生的屏幕链接的最左边？

是的，但您希望创建自己的SlidingPaneLayout实现并覆盖onTouchEvent（MotionEvent-ev）方法，如以下

public class SlidingPaneLayoutExtended extends SlidingPaneLayout {
public static final int DEFAULT_DRAGGING_START_X = -1;
public static final int SLIDE_FROM_LEFT_EDGE = 0;
private int startDraggingX = DEFAULT_DRAGGING_START_X;
public SlidingPaneLayoutExtended(Context context, AttributeSet attrs) {
    super(context, attrs);
}

public int getStartDraggingX() {
    return startDraggingX;
}
public void setStartDraggingX(int startX) {
    this.startDraggingX = startX;
}
@Override
public boolean onTouchEvent(MotionEvent ev) {
    if (startDraggingX > DEFAULT_DRAGGING_START_X) {
        if ((startDraggingX == SLIDE_FROM_LEFT_EDGE && ev.getAction() == )
                || ev.getX() <= DEFAULT_DRAGGING_START_X) {
            return super.onTouchEvent(ev);
        } else {
            return false;
        }
    }
    return super.onTouchEvent(ev);
}
}
