MaterialComponents AlertDialog文本颜色
MaterialComponents AlertDialog文本颜色
提问于 2020-05-15 11:59:14
阅读MaterialComponents theme alert dialog buttons和https://medium.com/@lcdsmao/material-design-custom-alert-dialog-5a9cab3ade11，我设置了新材料主题的AlertDialog按钮和文本颜色。
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.MaterialComponents.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
<!-- AlertDialog -->
<item name="materialAlertDialogBodyTextStyle">@style/MaterialAlertDialogTextTheme</item>
<item name="materialAlertDialogTheme">@style/MaterialAlertDialogButtonsTheme</item>
</style>
<!-- AlertDialog text -->
<style name="MaterialAlertDialogTextTheme" parent="MaterialAlertDialog.MaterialComponents.Body.Text">
<item name="android:textColor">@color/colorPrimary</item>
<item name="android:colorAccent">@color/colorPrimary</item>
<item name="colorAccent">@color/colorPrimaryitem>
<item name="android:textSize">14sp</item>
<item name="android:textStyle">bold</item>
</style>
<!-- AlertDialog buttons -->
<style name="MaterialAlertDialogButtonsTheme" parent="ThemeOverlay.MaterialComponents.MaterialAlertDialog">
<item name="buttonBarPositiveButtonStyle">@style/AlertDialog.Button</item>
...在创建AlertDialogFragment之后，使用
override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
super.onCreateDialog(savedInstanceState)
return MaterialAlertDialogBuilder(context!!).apply {
...
}.create()
}我得到了
正如您所看到的，按钮的颜色已经改变，但是文本的颜色和样式并没有改变。
然后我尝试了https://stackoverflow.com/a/51936236/2914140
<style name="AlertDialog" parent="Base.Theme.AppCompat.Light.Dialog">
<item name="android:textColorPrimary">#005B82</item>
<item name="colorAccent">#1b5e20</item>
</style>
...
return MaterialAlertDialogBuilder(context!!, R.style.AlertDialog).apply {并得到了
如何在不添加AlertDialog主题的情况下做同样的工作，只需要重新定义材料主题？

对于材料组件，您可以使用如下样式：
<!-- Alert Dialog -->
<style name="MyThemeOverlay.MaterialAlertDialog" parent="@style/ThemeOverlay.MaterialComponents.MaterialAlertDialog">
<!-- Title -->
<item name="materialAlertDialogTitleTextStyle">@style/MyTitle_MaterialAlertDialog.MaterialComponents.Title.Text</item>
<!-- Body -->
<item name="materialAlertDialogBodyTextStyle">@style/BodyTextAppearance.MaterialComponents.Body2</item>
<!-- Buttons -->
<item name="buttonBarPositiveButtonStyle">@style/PositiveButtonStyle</item>
<item name="buttonBarNegativeButtonStyle">@style/NegativeButtonStyle</item>
<item name="buttonBarNeutralButtonStyle">....</item>
</style>
<style name="PositiveButtonStyle" parent="@style/Widget.MaterialComponents.Button.TextButton.Dialog">
<item name="android:textColor">#FFFFFF</item>
<item name="backgroundTint">#00f</item>
</style>
<style name="NegativeButtonStyle" parent="@style/Widget.MaterialComponents.Button.TextButton.Dialog">
<item name="android:textColor">@color/primaryDarkColor</item>
</style>
<style name="MyTitle_MaterialAlertDialog.MaterialComponents.Title.Text" parent="@style/MaterialAlertDialog.MaterialComponents.Title.Text">
<item name="android:textColor">@color/colorAccent</item>
<item name="android:textAppearance">@style/MyTitle_TextAppearance.MaterialComponents.Subtitle1</item>
</style>
<style name="BodyTextAppearance.MaterialComponents.Body2" parent="@style/TextAppearance.MaterialComponents.Body2">
<item name="android:textColor">@color/colorAccent</item>
<item name="android:textSize">20sp</item>
<item name="android:textStyle">bold</item>
<item name="android:textAllCaps">true</item>
<item name="fontFamily">sans-serif-condensed-light</item>
</style>
然后，您可以在构造函数中引用此样式，如：
new MaterialAlertDialogBuilder(context,
R.style.MyThemeOverlay.MaterialAlertDialog)或者，您可以将其设置为应用程序主题中的默认设置：
<style name="AppTheme" parent="Theme.MaterialComponents.DayNight">
<item name="materialAlertDialogTheme">@style/MyThemeOverlay.MaterialAlertDialog
</item>
