Android Spinner自定义文本视图不可单击 [英] Android Spinner custom text view not clickable

问题描述

为什么使用自定义文本视图会阻止Spinner文本&项(但不是箭头)被单击，但是Android禁止的Spinner文本布局不是这种情况吗?

Why does using a custom text view prevent the Spinner text & items (yet not the arrow) from being clickable and yet this isn't the case with Android-prvoided Spinner text layouts?

使用时有效

    val arrayAdapter = ArrayAdapter(view!!.context, android.R.layout.simple_dropdown_item_1line, spinnerItems)
    arrayAdapter.setDropDownViewResource(android.R.layout.simple_dropdown_item_1line)

XML

<Spinner
        android:id="@+id/mySpinner"
        style="@style/Widget.AppCompat.Spinner.Underlined"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:spinnerMode="dialog"/>

    spinnerItems = arrayOf(
        "Cathedral of the Intercession of the Most Holy Theotokos on the Moat",
        "Ferapontov Monastery",
        "Historic Monuments of Novgorod and Surroundings",
        "Golden Mountains of Altai",
        "Historic Centre of Saint Petersburg and Related Groups of Monuments",
        "Bogoroditse-Smolensky Monastery",
        "White Monuments of Vladimir and Suzdal"
    )

    val arrayAdapter = ArrayAdapter(view!!.context, R.layout.spinner_item, spinnerItems)
    arrayAdapter.setDropDownViewResource(R.layout.spinner_item)

    mSpinner.adapter = arrayAdapter

spinner_item.xml

<?xml version="1.0" encoding="utf-8"?>
<TextView
        xmlns:android="http://schemas.android.com/apk/res/android"
        style="?android:attr/dropDownItemStyle"
        android:id="@+id/my_SpinnerItem"
        android:background="?android:attr/selectableItemBackground"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:clickable="true"
        android:focusable="true"
        android:paddingBottom="16dp"
        android:paddingTop="16dp"
        android:textColor="?android:attr/textColorPrimary" />
