基於viewpager的啓動頁界面代碼實現

class GuideActivity : Activity() {
override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_guide_kt)
    viewPager.adapter = GuideAdapter(getViewDatas())
}

class GuideAdapter(val list: List<View>) : PagerAdapter() {
    override fun getCount(): Int {
        return list.size
    }

    override fun isViewFromObject(view: View?, `object`: Any?): Boolean {
        return view == `object`
    }

    override fun instantiateItem(container: ViewGroup?, position: Int): Any {
        container!!.addView(list.get(position))
        return list.get(position)
    }

    override fun destroyItem(container: ViewGroup?, position: Int, `object`: Any?) {
        container!!.removeView(list.get(position))
    }
