java - 在堆栈 View 中水平滑动

Question

我在一个需要堆栈 View 的应用程序中。但是我必须实现水平滑动才能在堆栈 View 项目和 UI 之间切换，看起来就像普通的一样。请帮助我完成它。

我已经检查过这个 link .

但是里面的UI只是一个封面流程。我想让 UI 看起来和 stackview 一样。

我创建一个自定义堆栈 View

  public class custom_stackview extends StackView{

    float x1, x2, y1, y2, dx, dy;
    public custom_stackview(Context context, AttributeSet attrs) {
        super(context, attrs);
        // TODO Auto-generated constructor stub
    }
    public custom_stackview(Context context) {
        super(context);
        // TODO Auto-generated constructor stub
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        // TODO Auto-generated method stub
        super.onTouchEvent(event);

        switch(event.getAction()) {
            case(MotionEvent.ACTION_DOWN):
                x1 = event.getX();
                y1 = event.getY();
                break;
           case(MotionEvent.ACTION_MOVE):
           case(MotionEvent.ACTION_UP) :{
            x2 = event.getX();
            y2 = event.getY();
            dx = x2 - x1;
            dy = y2 - y1;

            // Use dx and dy to determine the direction
            if (Math.abs(dx) > Math.abs(dy)) {
                if (dx > 0) {// direction = "right";
                    showNext();
                } else {

                    showPrevious();


                }

            }
            }
         // Log.v("hiiiiiiiiiii", direction+re);
        }
        return true;

    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent event) {
        // TODO Auto-generated method stubLog.v("hiiiiiiiiiii","touched");
        Log.v("hiiiiiiiiiii","toucheddddddddd");
        //boolean re =false;


        return false;
    }

}

用作

 <package_name.custom_stackview
        android:id="@+id/stackview"
        android:layout_height="wrap_content"
        android:layout_width="match_parent"
        android:loopViews="true"
        />
