How to style buttons in Alert Dialog Fragment using Material Design?

问题

I'd like to change the default button styling on an alert dialog.

The standard Alert Dialog Fragment (in Android L) looks like this:

I'd like the right button to be styled as a normal button instead of a borderless button. Google itself seems to use this pattern in various dialogs, such as:

Does anyone know if this is possible, without recreating the whole dialog from scratch?

回答1:

You can style the button in the theme with attributes: android:buttonBarPositiveButtonStyle, android:buttonBarNegativeButtonStyle, and android:buttonBarNeutralButtonStyle.

Ok, the issue is solved automagically by updating to the (just released) release 21. Now the buttons are automatically in primary color :-)

EDIT: They are not in primary color, but in Android's basic turquoise..

This solution is for changing button color with material effect in AppCompatDialogFragment.

<android.support.v7.widget.AppCompatButton
android:id="@+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="20dp"
android:text="@string/buttin"
android:theme="@style/AppTheme.MyButton"
/>

Style file - v21

<style name="AppTheme.MyButton" parent="Theme.AppCompat.Dialog.Alert">
  <item name="android:colorButtonNormal">@color/button_color</item>
  <item name="android:textColor">@color/text_color</item>
</style>

Style file

<style name="AppTheme.MyButton" parent="Theme.AppCompat.Dialog.Alert">
  <item name="colorButtonNormal">@color/button_color</item>
  <item name="android:textColor">@color/text_color</item>
</style>
