Android textStyle:粗体不起作用

Question

我也见过类似的问题，但possible solutions (这是我最后一次尝试)行不通。问题是，我不能将文本设置为粗体，也不能更改其大小，它总是显示为非粗体和相同大小。

我需要以粗体显示@+id/contactName。

<TextView
            android:id="@+id/contactName"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="start"
            android:ellipsize="end"
            android:maxLines="1"
            android:overScrollMode="never"
            android:paddingEnd="4dp"
            android:textAppearance="@style/contactListTextPrimary"
            tools:ignore="RtlSymmetry"
            tools:text="Contact title" />

<style name="contactListTextPrimary" parent="@android:style/TextAppearance.Medium">
    <item name="android:textColor">?android:attr/textColorPrimary</item>
    <item name="android:textStyle">bold</item>
    <item name="android:textSize">16sp</item>
</style>

上面的代码并没有使文本粗体化，它始终保持原样。下面是完整的styles.xml文件。

<resources>
    <style name="AppTheme" parent="Theme.MaterialComponents.Light.NoActionBar">
        <item name="windowNoTitle">true</item>

Answer 1

你说contactListTextPrimary风格是

<style name="contactListTextPrimary" parent="@android:style/TextAppearance.Medium">
    <item name="android:textColor">?android:attr/textColorPrimary</item>
    <item name="android:textStyle">bold</item>
    <item name="android:textSize">16sp</item>
</style>

但是在完整的样式文件中

<style name="contactListTextPrimary" parent="@android:style/TextAppearance.Medium">
    <item name="android:textColor">?android:attr/textColorPrimary</item>
</style>

根据更长的版本使它们匹配，您应该会看到粗体的字体。
