Question

我试图创建水平数字选择器，但是EditText的高度越来越大。

我在styles.xml中用<item name="android:background">@null</item>删除了EditText的底部边框

        app:layout_constraintStart_toEndOf="@id/num_picker_layout"
        app:layout_constraintTop_toTopOf="parent"/>
</androidx.constraintlayout.widget.ConstraintLayout>

drawable / number_picker.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
    <stroke android:width="1dp" android:color="#CCCCCC"/>
</shape>

styles.xml

<resources>
    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.MaterialComponents.Light.NoActionBar">
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>

    <style name="numberPickerBtn">
        <item name="backgroundTint">#E5E5E5</item>
        <item name="android:textColor">#757575</item>
        <item name="android:background">@drawable/number_picker</item>
    </style>
    <style name="numberPickerEt" parent="Widget.AppCompat.EditText">
        <item name="android:background">@drawable/number_picker</item>

当前状态： https://habrastorage.org/webt/5c/f4/f1/5cf4f1d8911ce534938275.png

在这里我用红色填充以显示与父项匹配的按钮，但它们不匹配 https://habrastorage.org/webt/5c/f4/f7/5cf4f799b9116853603442.png
