无法覆盖android 21下样式上的按钮的textAllCaps [英] Can't override textAllCaps for buttons on style under android 21

问题描述

这就是我设置按钮的方式.

This is how I set my buttons.

<Button
    android:id="@+id/button_login"
    style="@style/ButtonStyle"
    android:text="@string/button_login" />

这是我在values文件夹上的样式.

This is my style on values folder.

<style name="ButtonStyle" parent="ButtonStyleBase" />

<style name="ButtonStyleBase">
    <item name="android:layout_width">match_parent</item>
    <item name="android:layout_height">wrap_content</item>
    <item name="android:layout_marginTop">@dimen/padding</item>
    <item name="android:textSize">@dimen/font_regular</item>
    <item name="android:textColor">@color/text_regular</item>
    <item name="android:background">@drawable/shape_clickable</item>
</style>

这是我在values-v21文件夹上的风格

And this is my style on values-v21 folder

<style name="ButtonStyle" parent="ButtonStyleBase">
    <item name="textAllCaps">false</item>
    <item name="android:textColor">#000000</item>
</style>

但是按钮上的文本始终是大写的.但是，如果我直接将其设置在按钮上，它将恢复正常.我更改了颜色以查看是否正在使用api 21的样式，并且在api 21上按钮文本的颜色更改为黑色.我知道默认主题将按钮的textAllCaps设置为true，因为Google认为它会超级重复-cool，但是它不应该优先考虑我的风格吗?

But the text is always uppercase on buttons. If I set it directly on the button it will get back to normal, though. I changed the color to see if the style for api 21 was being used and it was, the button text color changed to black on api 21. I know the default theme sets textAllCaps as true for buttons because google thought it would be super-duper-cool, but shouldn't it prioritize my style?

没关系，我忘了在样式上写"android:".

neverming, I forgot to write "android:" on the style.

推荐答案

我遇到了同样的问题，这对我有用:

I had the same issue and this is what worked for me:

<style name="Theme.CustomTheme" parent="@style/Theme.AppCompat.Light.DarkActionBar">
    <item name="android:textAppearanceButton">@style/CustomTheme.ButtonTextAppearance</item>
</style>

<style name="CustomTheme.ButtonTextAppearance" parent="@style/Base.TextAppearance.AppCompat.Button">
    <item name="textAllCaps">false</item>
    <item name="android:textAllCaps">false</item>
</style>
