Material Design not styling alert dialogs

问题

I\'ve added the appCompat material design to my app and it seems that the alert dialogs are not using my primary, primaryDark, or accent colors.

Here is my base style:

<style name=\"MaterialNavyTheme\" parent=\"@style/Theme.AppCompat.Light.DarkActionBar\">
    <item name=\"colorPrimary\">@color/apptheme_color</item>
    <item name=\"colorPrimaryDark\">@color/apptheme_color_dark</item>
    <item name=\"colorAccent\">@color/apptheme_color</item>
    <item name=\"android:textColorPrimary\">@color/action_bar_gray</item>
</style>

Based on my understanding the dialogs button text should also use these colors. Am I wrong on my understanding or is there something more I need to do?

Solution:

The marked answer got me on the right track.

<style name=\"MaterialNavyTheme\" parent=\"@style/Theme.AppCompat.Light.DarkActionBar\">
    <item name=\"colorPrimary\">@color/apptheme_color</item>
    <item name=\"colorPrimaryDark\">@color/apptheme_color_dark</item>
    <item name=\"colorAccent\">@color/apptheme_color</item>
    <item name=\"android:actionModeBackground\">@color/apptheme_color_dark</item>
    <item name=\"android:textColorPrimary\">@color/action_bar_gray</item>
    <item name=\"sdlDialogStyle\">@style/DialogStyleLight</item>
    <item name=\"android:seekBarStyle\">@style/SeekBarNavyTheme</item>
</style>

<style name=\"StyledDialog\" parent=\"Theme.AppCompat.Light.Dialog\">
    <item name=\"colorPrimary\">@color/apptheme_color</item>
    <item name=\"colorPrimaryDark\">@color/apptheme_color_dark</item>
    <item name=\"colorAccent\">@color/apptheme_color</item>
</style>

UPDATED ON Aug 2019 WITH The Material components for android library:

With the new Material components for Android library you can use the new com.google.android.material.dialog.MaterialAlertDialogBuilder class, which extends from the existing androidx.appcompat.AlertDialog.Builder class and provides support for the latest Material Design specifications.

Just use something like this:

new MaterialAlertDialogBuilder(context)
            .setTitle("Dialog")
            .setMessage("Lorem ipsum dolor ....")
            .setPositiveButton("Ok", /* listener = */ null)
            .setNegativeButton("Cancel", /* listener = */ null)
            .show();

You can use in your theme something like:

 <!-- Base application theme. -->
 <style name="AppTheme" parent="Theme.MaterialComponents.Light">
    ...
    <item name="materialAlertDialogTheme">@style/ThemeOverlay.MaterialComponents.MaterialAlertDialog</item>
 </style>

You can also use the constructor:

new MaterialAlertDialogBuilder(context, R.style.ThemeOverlay_MaterialComponents_MaterialAlertDialog)

WITH SUPPORT LIBRARY:

With the new AppCompat v22.1 you can use the new android.support.v7.app.AlertDialog.

Just use a code like this:

import android.support.v7.app.AlertDialog

AlertDialog.Builder builder =
       new AlertDialog.Builder(this, R.style.AppCompatAlertDialogStyle);
builder.setTitle("Dialog");
builder.setMessage("Lorem ipsum dolor ....");
builder.setPositiveButton("OK", null);
builder.setNegativeButton("Cancel", null);
builder.show();

And use a style like this:

<style name="AppCompatAlertDialogStyle" parent="Theme.AppCompat.Light.Dialog.Alert">
        <item name="colorAccent">#FFCC00</item>
        <item name="android:textColorPrimary">#FFFFFF</item>
        <item name="android:background">#5fa3d0</item>
    </style>

Otherwise you can define in your current theme:

<style name="AppTheme" parent="Theme.AppCompat.Light">
    <!-- your style -->
    <item name="alertDialogTheme">@style/AppCompatAlertDialogStyle</item>
</style>

and then in your code:

 import android.support.v7.app.AlertDialog

    AlertDialog.Builder builder =
           new AlertDialog.Builder(this);

Here the AlertDialog on Kitkat:

回答2:

when initializing dialog builder, pass second parameter as the theme. It will automatically show material design with API level 21.

AlertDialog.Builder builder = new AlertDialog.Builder(this, AlertDialog.THEME_DEVICE_DEFAULT_DARK);

or,

AlertDialog.Builder builder = new AlertDialog.Builder(this, AlertDialog.THEME_DEVICE_DEFAULT_LIGHT);

回答3:

AppCompat doesn't do that for dialogs (not yet at least)

EDIT: it does now. make sure to use android.support.v7.app.AlertDialog

回答4:

You can consider this project: https://github.com/fengdai/AlertDialogPro

It can provide you material theme alert dialogs almost the same as lollipop's. Compatible with Android 2.1.

You could use

Material Design Library

Material Design Library made for pretty alert dialogs, buttons, and other things like snack bars. Currently it's heavily developed.

Guide, code, example - https://github.com/navasmdc/MaterialDesignLibrary

Happy coding ;)

回答6:

Try this library:

https://github.com/avast/android-styled-dialogs

It's based on DialogFragments instead of AlertDialogs (like the one from @afollestad). The main advantage: Dialogs don't dismiss after rotation and callbacks still work.

回答7:

For some reason the android:textColor only seems to update the title color. You can change the message text color by using a

SpannableString.AlertDialog.Builder builder = new AlertDialog.Builder(new ContextThemeWrapper(this, R.style.MyDialogTheme));

AlertDialog dialog = builder.create();
                Spannable wordtoSpan = new SpannableString("I know just how to whisper, And I know just how to cry,I know just where to find the answers");
                wordtoSpan.setSpan(new ForegroundColorSpan(Color.BLUE), 15, 30, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
                dialog.setMessage(wordtoSpan);
                dialog.show();
