我正在尝试使用implementation 'com.google.android.material:material:1.0.0'
库提供的新样式来设置材质按钮的样式。问题是按钮的样式不正确。例如,我有2个不同的活动,使用完全相同的主题,按钮使用完全相同的代码,但是拒绝使用正确的样式,在Android预览屏幕上看起来正确,但是在实际应用中却不正确。
此外,我通过设置style="myButtonStyleWhatever"
来手动覆盖一组按钮的样式,但这也被忽略了。这变得非常令人沮丧,所以我希望有人能帮助您。

答案 0 :(得分:1)
您发布的样式没有意义。
ToolBarStyle
和WhiteButtons
样式,但是您没有在任何地方使用它们。MyMaterialTheme
(而不是MyMaterialTheme.Base
);我希望您不要期望MyMaterialTheme.Base
会自动继承它,因为指定parent
会覆盖点符号继承。MyMaterialTheme.Base
内容都相同;为什么要在三个地方指定它?此外,您发布的所有样式似乎都不会影响MaterialButton
小部件(colorPrimary
除外)。因此,很难确切知道问题出在哪里。
总而言之,the GitHub documentation中提供了MaterialButton
支持的属性列表。值得注意的是,android:background
不支持MaterialButton
。来自the JavaDoc:
请勿使用
android:background
属性。MaterialButton
管理其自己的背景可绘制对象,设置新的背景意味着MaterialButton
不能再保证其引入的新属性将正常运行。如果更改了默认背景,MaterialButton
将无法保证行为明确。
我怀疑您所看到的是两个屏幕上不同的colorPrimary
定义的结合以及不支持android:background
的事实。
如果要手动覆盖按钮的背景色,请在app:backgroundTint
标签上使用<MaterialButton>
属性。如果要在<style>
标记中指定该标记,则不使用名称空间:
<item name="backgroundTint">@color/your_background_color</item>
