片段显示为空白屏幕？
我正在开发一个新的应用程序，但问题是，当我单击菜单中的TherapyInformation时，它显示TherapyInformation下面的空白屏幕
但是，在StartSessionFragment上，当用户单击警告图标时，它清晰地显示TherapyInformation，如下图所示。
当用户单击TherapyInformation时，我想要实现的目标是，我想像在StartSessionFragment中那样显示Therapy信息。
在TherapyInformationFragment.kt类之下
class TherapyInformationFragment : BaseMvpFragment(), TherapyInfoView,
OnBackPressed {
override fun showTherapy(therapies: ArrayList<Therapy) {
companion object {
var RED_FLAG = "RED_FLAG"
var YELLOW_FLAG = "YELLOW_FLAG"
var ORANGE_FLAG = "ORANGE_FLAG"
}
val presenter = TherapyInformationPresenter(this)
private var goToSchedule = false
var packages: MutableList<TherapyPackage? = null
var position: Int = 0
override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?,
savedInstanceState: Bundle?): View? {
rootView = inflater.inflate(R.layout.fragment_therapy_information, container,
false)
return rootView
}
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
if (Build.VERSION.SDK_INT = Build.VERSION_CODES.LOLLIPOP) {
super.onViewCreated(view, savedInstanceState)
}
goToSchedule = arguments?.containsKey("ids") ?: false
if (arguments != null && arguments!!.containsKey("ids"))
presenter.getTherapyInformation(arguments!!.getIntegerArrayList("ids"))
else if (arguments?.containsKey("therapy_package_id") == true)
presenter.getTherapyPackageInformation(arguments?.getInt("therapy_package_id"))
else presenter.getAllTherapyInformation()
initToolbar()
imageBack.setOnClickListener {
if (position 0)
viewPager.setCurrentItem(viewPager.currentItem - 1, true)
}
imageNext.setOnClickListener {
if (position != packages?.lastIndex) {
viewPager.setCurrentItem(viewPager.currentItem + 1, true)
} else {
if (goToSchedule) {
val data = Bundle()
data.putInt(SCREEN_TRANSITION_DIRECTION, Gravity.END)
data.putString(ScheduleFragment.MODE, ScheduleFragment.DIAGNOSTIC_FINISH_MODE)

attentionIcon.visibility = if (it.key.endsWith("_rf") || it.key.endsWith("_yf") || it.key.endsWith("_of"))

else
View.GONE
}
}
低于TherapyInfoView.kt
interface TherapyInfoView : BaseMvpView {
fun showTherapy(therapies: ArrayList<Therapy>)
fun showTherapyPackages(packages: List<TherapyPackage>)
}
在我的Presenter.kt类下面
class TherapyInformationPresenter(val view: TherapyInfoView) : BaseMvpPresenter() {
val db = TherapyDatabaseV2()
fun getTherapyInformation(ids: List<Int>) {
view.showTherapy((arrayListOf(*ids.map { db.getTherapyById(it) }.mapNotNull { it }.toTypedArray())))
}
fun getAllTherapyInformation() {
view.showTherapy(db.getAllTherapy())
}
fun getTherapyPackageInformation(int: Int?) {
view.showTherapyPackages(db.getPackages())
}
}
