我尝试将其添加到styles.xml中,如下所示:
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Main theme colors -->
<!-- your app branding color for the app bar -->
<item name="colorPrimary">@color/primary</item>
<!-- darker variant for the status bar and contextual app bars -->
<item name="colorPrimaryDark">@color/primary_dark</item>
<!-- theme UI controls like checkboxes and text fields -->
<item name="colorAccent">@color/accent</item>
<!-- buttons will not have shadows -->
<item name="android:buttonStyle">@style/Widget.AppCompat.Button.Borderless</item>
<item name="android:textAppearanceButton">@style/DefaultButtonTextStyle</item>
<item name="android:colorBackground">@android:color/white</item>
</style>
<!--The button text style to be used throughout the app-->
<style name="DefaultButtonTextStyle" parent="@style/Base.TextAppearance.AppCompat.Button">
<!-- Ensure that the buttons are all caps even pre Lollipop-->
<item name="android:textAllCaps">true</item>
<item name="textAllCaps">true</item>
</style>
答案 0 :(得分:1)
您只需为按钮创建自定义样式
<style name="CustomButton">
<item name="android:layout_height">wrap_content</item>
<item name="android:layout_width">wrap_content</item>
<item name="android:layout_centerVertical">true</item>
<item name="android:textAllCaps">true</item>
</style>
然后将其设置为您的按钮,如:
<Button
android:id="@+id/total_bill"
style="@style/CustomButton" />
或者您可以执行以下操作:
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="buttonStyle">@style/MyButton</item>
</style>
<style name="MyButton" parent="Widget.AppCompat.Button">
<item name="android:textAllCaps">true</item>
</style>
第二种方法将为整个应用程序中的所有Button更改它。另一种方法是扩展Button并创建一个自定义Button,其中textcaps设置为true并使用该Button而不是默认值。
