导航抽屉中的PlaceAutocomplete

Question

我试图将PlaceAutocomplete放入导航抽屉中。 此外，任何在github上发布有placeautocomplete api的项目都可以作为答案或任何来源，如何使用placeautocomplete制作自定义导航抽屉

这是我的代码：

搜索片段布局：

<FrameLayout
android:id="@+id/autocompleteHolder"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="@+id/customViewPager"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">

<fragment
    android:id="@+id/autocomplete_fragment"
    android:name="com.x.egerg.fragments.AutoComplete"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

DrawerLayout

    <include
        layout="@layout/app_bar_main"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <android.support.design.widget.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:fitsSystemWindows="true"
        app:headerLayout="@layout/searchfraglay"
        app:menu="@menu/activity_main_drawer" />

</android.support.v4.widget.DrawerLayout>

自动完成片段

class AutoComplete : Fragment(), PlaceSelectionListener {
override fun onCreate(savedInstanceState: Bundle?) {
    val autocompleteFragment = fragmentManager!!.findFragmentById(R.id.autocomplete_fragment) as SupportPlaceAutocompleteFragment
    autocompleteFragment.setOnPlaceSelectedListener(this)
    super.onCreate(savedInstanceState)
}
override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?,
                          savedInstanceState: Bundle?): View? {

    return inflater.inflate(R.layout.searchfraglay, container, false)
    }


override fun onPlaceSelected(p0: Place?) {
    Log.d("OnPlaceSelected", p0?.name.toString())
}

override fun onError(p0: Status?) {
    Log.d("OnPlaceSelected", "error")

}

}

在MainActivity内部

nav_view.inflateHeaderView(R.layout.searchfraglay)

    val ft = supportFragmentManager.beginTransaction()
    ft.replace(R.id.autocompleteHolder, AutoComplete())
    ft.commit()

logcat的

Answer 1

我应该在MainActivity内实现PlaceSelectionListener ，而不是分段实现。
