Question

我正在制作一个浏览器。作为基础，请使用Viewpager和FragmentStatePagerAdapter。添加新片段后，会将最后一个片段移到侧面，或者屏幕上已经出现了移位。

我没有发现类似的问题。

override fun getItem(position: Int): Fragment = listOpenTabs[position].fragment

override fun getCount(): Int {
    return listOpenTabs.size
}

private var listOpenTabs = mutableListOf<TabsModel>()

fun removeAt(position: Int) {
    onClickCloseTab(listOpenTabs[position])
}

fun setData(list: MutableList<TabsModel>) {
    listOpenTabs = list
}

//自定义查看器

可私有变量可滑动：布尔值=否构造函数（上下文：上下文）：超级（上下文）

constructor(context: Context, attrs: AttributeSet) : super(context, attrs) {
    this.swipeable = true
}

@SuppressLint("ClickableViewAccessibility")
override fun onTouchEvent(event: MotionEvent): Boolean {
    return if (this.swipeable) {
        super.onTouchEvent(event)
    } else false
}

override fun onInterceptTouchEvent(event: MotionEvent): Boolean {
    return if (this.swipeable) {
        super.onInterceptTouchEvent(event)
    } else false
}

fun setSwipeable(swipeable: Boolean) {
    this.swipeable = swipeable
}

//活动在活动中，我将这种方法用于比例查看器和打开标签页

    if (dm2!!.widthPixels - viewPager.width < 5) {
        viewPager.pageMargin = 40
        llayoutviewpage.gravity = CENTER_IN_PARENT
        val pvhX = PropertyValuesHolder.ofFloat("scaleX", 1f, 0.8f)
        val pvhY = PropertyValuesHolder.ofFloat("scaleY", 1f, 0.8f)
        val scale = ObjectAnimator.ofPropertyValuesHolder(viewPager, pvhX, pvhY)
        scale.duration = 100
        scale.start()
        val Rlparam =
            RelativeLayout.LayoutParams(dm2!!.widthPixels * 8 / 10, dm2!!.heightPixels * 8 / 10)
        Rlparam.addRule(CENTER_IN_PARENT)
        llayoutviewpage.layoutParams = Rlparam
        viewPager.setSwipeable(true)
        nav_bar.visibility = View.GONE
        addTab.visibility = View.VISIBLE
        viewPager.currentItem = viewPager.currentItem
    } else {
        viewPager.pageMargin = 0
        llayoutviewpage.gravity = CENTER_IN_PARENT
        val pvhX = PropertyValuesHolder.ofFloat("scaleX", 0.8f, 1f)
        val pvhY = PropertyValuesHolder.ofFloat("scaleY", 0.8f, 1f)
        val scale = ObjectAnimator.ofPropertyValuesHolder(viewPager, pvhX, pvhY)
        scale.duration = 100
        scale.start()
        val Rlparam2 = RelativeLayout.LayoutParams(dm2!!.widthPixels, dm2!!.heightPixels)
        Rlparam2.addRule(CENTER_IN_PARENT)
        llayoutviewpage.layoutParams = Rlparam2
        viewPager.setSwipeable(false)
        nav_bar.visibility = View.VISIBLE
        addTab.visibility = View.GONE
        viewPager.currentItem = viewPager.currentItem
    }

每个添加的片段的片段显示不正确，最后一个片段移到侧面
