I have basic knowledge of animations, but how to set globally same animations for opening/closing dialogs within my app?
I have a preference screen with toolbar on top (with some menu items). And clicking on menu, or preferences opens dialogs.
How to set same dialog animations within my app, or at least within certain activity? So whatever dialog I open, it will always be same animation?
You can create a theme for your dialogs with the desired animations and apply it to your app's theme in styles.xml like this:
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
<!-- Apply your custom dialog theme here. -->
<item name="android:dialogTheme">#style/CustomDialog</item>
<item name="android:alertDialogTheme">#style/CustomDialog</item>
</style>
<style name="CustomDialog" parent="Theme.AppCompat.Light.Dialog">
<item name="android:windowAnimationStyle">#style/CustomDialogAnimation</item>
</style>
<style name="CustomDialogAnimation">
<item name="android:windowEnterAnimation">#android:anim/slide_in_left</item>
<item name="android:windowExitAnimation">#android:anim/slide_out_right</item>
</style>
That will apply the enter and exit animations to all of your dialogs âđģI just tested it myself and it worked, let me know if it works for you đ
Use this in alert dialog,
if (alertDialogBuilder.getWindow() != null)
alertDialogBuilder.getWindow().getAttributes().windowAnimations = R.style.DialogTheme; //style id
In styles.xml define above Dialog Theme like below:
<style name="DialogTheme">
<item name="android:windowEnterAnimation">#anim/slide_left</item>
<item name="android:windowExitAnimation">#anim/slide_right</item>
</style>
Happy Coding :)

I'm building an application with React Native, and with very little knowledge of Android. Mostly this is not a problem, but I would like to use native components for alerts. React native provides a way to launch a native alert, but there is no way to style it from React code. So I have resorted to suggestions online about using the /res/values/styles.xml configuration.
It's possible that it's just my lack of knowledge in Android showing here, but I can't seem to get a good solid reference of XML styling attributes, where they go, how they're structured etc.
My problem currently is that my buttons are showing up with background colours, which I don't want. I want to have standard material design text buttons like you would expect on Android. In the image below, "OK" should show up with green text, and no background.
Here is my styles.xml
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.MaterialComponents.NoActionBar">
<!-- Customize your theme here. -->
<item name="android:textColor">#ffffff</item>
<item name="android:statusBarColor">#16192E</item>
<item name="colorPrimaryDark">#6fca3a</item>
<item name="colorPrimary">#6fca3a</item>
<item name="colorOnSurface">#ffffff</item>
<item name="android:colorBackground">#16192E</item>
<item name="android:colorBackgroundFloating">#16192E</item>
<item name="alertDialogTheme">#style/AlertDialogTheme</item>
</style>
<style name="AlertDialogTheme" parent="ThemeOverlay.MaterialComponents.Dialog.Alert">
<item name="buttonBarNegativeButtonStyle">#style/NegativeButtonStyle</item>
<item name="buttonBarPositiveButtonStyle">#style/PositiveButtonStyle</item>
<item name="buttonBarNeutralButtonStyle">#style/NeutralButtonStyle</item>
</style>
<style name="NeutralButtonStyle" parent="Widget.MaterialComponents.Button.TextButton.Dialog">
<item name="android:textColor">#f00</item>
</style>
<style name="NegativeButtonStyle" parent="Widget.MaterialComponents.Button.TextButton.Dialog">
<item name="android:textColor">#f00</item>
</style>
<style name="PositiveButtonStyle" parent="Widget.MaterialComponents.Button.TextButton.Dialog">
<item name="android:textColor">#00f</item>
</style>
</resources>
And if anyone can point me in the direction for figuring this stuff out myself that would also be great.
EDIT
This is not a question about how to change the style of a button that I have rendered onto the page in code. This question is specifically about how to style the buttons on a built in native android alert dialog. There does not appear to be a way to do it through JavaScript/React, and the fact that I am able to style the background, text colour, and button colour of the alert lead me to believe that it can be done through the styles.xml file, without having to actually write Android code to extend the Alert Dialog.
In native Android using a Material Components theme you can customize globally the alert dialog using:
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.MaterialComponents.Light">
...
<item name="materialAlertDialogTheme">#style/AlertDialogTheme</item>
</style>
with:
<!-- Alert Dialog -->
<style name="AlertDialogTheme" parent="#style/ThemeOverlay.MaterialComponents.MaterialAlertDialog">
<item name="buttonBarPositiveButtonStyle">#style/PositiveButtonStyle</item>
<item name="buttonBarNegativeButtonStyle">#style/NegativeButtonStyle</item>
<item name="buttonBarNeutralButtonStyle">....</item>
</style>
Can we modify/custom ourBiometricPrompt?
For example right now i use smth like this:
BiometricPrompt.Builder(AppResources.appContext)
.setTitle("title")
.setSubtitle("subTitle")
.setDescription("description")
.setNegativeButton("Cancel", AppResources.appContext?.mainExecutor,
DialogInterface.OnClickListener { dialogInterface, i -> biometricCallback.onAuthenticationCancelled() })
.build()
.authenticate(CancellationSignal(), AppResources.appContext?.mainExecutor,
BiometricCallbackV28(biometricCallback))
Do I have the ability to change the style of the text, title, negativeButton color?
Update2: beta01
The change with the alpha version was that the fingerprint dialog uses android.app.AlertDialog and the new beta01 uses androidx.appcompat.app.AlertDialog which has a private style.
Then to override that style we have to override androidx.appcompat.R.attr.alertDialogTheme reference in our styles.xml, we can do it replacing <item name="android:alertDialogTheme">#style/CustomAlertTheme</item> by <item name="alertDialogTheme">#style/CustomAlertTheme</item> in my case thay I only wanted to change the button text color, I just added <item name="buttonBarNegativeButtonStyle">#style/NegativeButtonStyle</item> and the same for posivtive, because replacing alertDialogTheme changes other things that I did not want to.
My styles.xml now:
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorAccent">#color/colorAccent</item>
<item name="android:textColor">#color/black</item>
<item name="android:buttonStyle">#style/WibleButtonStyle</item>
<item name="buttonBarNegativeButtonStyle">#style/NegativeButtonStyle</item>
</style>
<style name="NegativeButtonStyle" parent="Widget.AppCompat.Button.ButtonBar.AlertDialog">
<item name="android:textSize">16sp</item>
<item name="android:textColor">#color/dark_blue</item>
</style>
Update: beta01
This trick is not working anymore. I'll try if I can find another way to do it.
I found two ways to do it, none of these are specific for the BiometricPrompt, one is to override the theme button style:
<item name="android:buttonStyle">#style/CustomButtonStyle</item>
another option is to override your alert dialog theme:
AppTheme style
<item name="android:alertDialogTheme">#style/AlertDialogTheme</item>
<style name="AlertDialogTheme" parent="ThemeOverlay.AppCompat.Dialog.Alert">
<item name="android:buttonBarNegativeButtonStyle">#style/NegativeButtonStyle</item>
<item name="android:buttonBarPositiveButtonStyle">#style/PositiveButtonStyle</item>
</style>
<style name="NegativeButtonStyle" parent="Widget.AppCompat.Button.ButtonBar.AlertDialog">
<item name="android:textSize">10sp</item>
<item name="android:textColor">#color/primary_text</item>
</style>
<style name="PositiveButtonStyle" parent="Widget.AppCompat.Button.ButtonBar.AlertDialog">
<item name="android:textColor">#color/primary_text</item>
</style>
And then you can apply a specific theme to a specific activity. Maybe they could open the API to allow styles, but I had to change the color because it was impossible to see the buttons (everything was white) and this is what I found to solve my problem. I hope it helps you.
You can't set properties on the prompt that aren't exposed through its Builder - the UI is provided by the system, and is designed to be uniform throughout all apps.
This is sort of the main point of this API, this way the user becomes familiar with the prompt and knows that whatever they're interacting with is safe to use.
Can we modify/custom our BiometricPrompt?
The BiometricPrompt uses the "buttonStyle" style that is set for your theme, which you can adjust in the styles.xml
Keep in mind that this is the default button style, so if you do not want other buttons to change you would have to assign buttons etc. their own style. (and dialogs etc.)
For example, if you only want the text color to be different for the BiometricPrompt, you could do something like this:
<style name="myTheme" parent="Theme.AppCompat.DayNight.NoActionBar">
<item name="buttonStyle">#style/ButtonPrimaryStyle</item>
</style>
<style name="ButtonPrimaryStyle" parent="ButtonParentStyle">
<item name="android:textColor">454545</item>
</style>
<style name="ButtonPrimaryStyleMain" parent="ButtonPrimaryStyle">
<item name="android:textColor">e2e2e2</item>
</style>
This would make the BiometricPrompt have a dark grey text for the cancel button, while every button with the "ButtonPrimaryStyleMain" style will have a lightgrey, almost white, text color.
You would also have to assign this theme to your application in the manifest.
<application
android:theme="#style/myTheme"
In my Android app, I am using various custom themes in different activities, all of which work fine. All these themes use the same custom styles for buttons, edit controls etc.
My preferences use standard Preference activities, which I define in XML and style via the manifest.
However, when I have a preference that causes an alert dialog to get launched, for example a ListPreference, the dialog uses the standard buttons. It does seem to use my custom EditText style in the EditTextPreference... but not my background or text colour.
Anyone have any idea why this is happening ?
Some of the code:
Styles:
<style name="Theme.Prefs" parent="#android:style/Theme.Holo.Light">
<item name="android:windowBackground">#drawable/background</item>
<item name="android:buttonStyle">#style/CustomButtonStyle</item>
<item name="android:editTextStyle">#style/CustomEditTextStyle</item>
</style>
<style name="CustomButtonStyle" parent="#android:style/Widget.Holo.Button">
<item name="android:background">#drawable/custom_button</item>
<item name="android:textSize">#dimen/dialog_text_size_normal</item>
<item name="android:textColor">#color/dialog_control_colour</item>
</style>
<style name="CustomEditTextStyle" parent="#android:style/Widget.Holo.EditText">
<item name="android:background">#drawable/custom_textfield</item>
<item name="android:textColor">#color/dialog_control_colour</item>
<item name="android:textSize">#dimen/dialog_text_size_normal</item>
</style>
And in the manifest:
<activity
android:name="com.breadbun.prefs.MainPreferencesActivity"
android:theme="#style/Theme.Prefs"
android:screenOrientation="portrait">
</activity>
To customize the alertDialog you need to add the second row to your main theme, and then customize the DialogStyle the way you want it.
<style name="AppTheme" parent="android:Theme.Material">
<item name="android:alertDialogTheme">#style/DialogStyle</item>
</style>
<style name="DialogStyle" parent="android:Theme.Material.Dialog.Alert">
</style>
I've created a custom theme for my app, and it looks great! However, I've noticed that some default platform dialogs, such as the context menu when long-pressing an EditText doesn't show correctly.
On the left, a context menu through my app. On the right, a standard context menu through a platform app.
Here's my style.xml:
<resources xmlns:android="http://schemas.android.com/apk/res/android">
<style name="Theme.Styled" parent="Theme.Sherlock">
<!-- ... various app styles ... -->
<item name="android:alertDialogStyle">#style/DialogHolo</item>
<item name="android:dialogTheme">#style/DialogHolo</item>
</style>
<style name="DialogHolo" parent="android:style/Theme.Dialog">
<item name="android:fullDark">#drawable/bg_dialog_full</item>
<item name="android:topDark">#drawable/bg_dialog_top</item>
<item name="android:centerDark">#drawable/bg_dialog_middle</item>
<item name="android:bottomDark">#drawable/bg_dialog_bottom</item>
<item name="android:fullBright">#drawable/bg_dialog_full</item>
<item name="android:centerBright">#drawable/bg_dialog_middle</item>
<item name="android:bottomBright">#drawable/bg_dialog_bottom</item>
<item name="android:bottomMedium">#drawable/bg_dialog_bottom</item>
<item name="android:centerMedium">#drawable/bg_dialog_middle</item>
<item name="android:textColor">#ffe6e7e8</item>
</style>
</resources>
Is it possible to either have these dialogs use the default style or get the text to appear in the desired text color?
I never found an elegant solution for this, and instead simply provided a theme defined separately in my style.xml when displaying a custom dialog.
Is there a way I can change all the alert dialogs appearing in my Android application? I want to change the dialogs that are system generated as well (like the Edit Text dialog that opens up when you long tap on any EditText). I want to change the title font color and size of all the dialogs in my app.
Is there a way to do it?
I have tried setting android:alertDialogTheme in my theme. But it seems to be not working. Code following -
<style name="Theme.DLight" parent="android:Theme.Light.NoTitleBar">
<item name="android:alertDialogTheme">#style/DialogStyle</item>
</style>
and
<style name="DialogStyle" parent="android:Theme" >
<item name="android:windowBackground">#drawable/background_holo_light</item>
<item name="android:textColor">#014076</item>
</style>
EDIT
I'm not invoking a dialog from my code. It's just the default dialog
that appears when you long click on any EditText. Generally it
contains the keyboard options like Select word, Select all, Input
method etc.
In you dialog theme, the attribute you need to modify windowTitleStyle. There, reference a style for your title and define a text appearance for this title. For example, to display your title red and bold:
<style name="AppTheme" parent="#android:style/Theme.Holo">
...
<item name="alertDialogTheme">#style/AppTheme.AlertDialog</item>
</style>
<style name="DialogStyle" parent="#style/Theme.Holo.Dialog.Alert">
...
<item name="android:windowTitleStyle">#style/DialogWindowTitle_Custom</item>
</style>
<style name="DialogWindowTitle_Custom" parent="#style/DialogWindowTitle_Holo">
<item name="android:maxLines">1</item>
<item name="android:scrollHorizontally">true</item>
<item name="android:textAppearance">#style/TextAppearance_DialogWindowTitle</item>
</style>
<style name="TextAppearance_DialogWindowTitle" parent="#android:style/TextAppearance.Holo.DialogWindowTitle">
<item name="android:textColor">#android:color/holo_red_light</item>
<item name="android:textStyle">bold</item>
</style>
If you want to style a little bit more your AlertDialog, I wrote a blog post detailing the steps.
In styles.xml:
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
//All your other styles and add the one mntioned below.
<item name="alertDialogTheme">#style/AlertDialogStyle</item>
</style>
In the styles of AlertDialog add:
<style name="AlertDialogStyle" parent="Theme.AppCompat.Light.Dialog.Alert">
<item name="colorAccent">#color/colorAccent</item>
<item name="android:textColorPrimary">#color/primary_text</item>
<item name="android:editTextColor">#color/primary_text</item>
<item name="android:background">#color/white</item>
<item name="android:windowTitleStyle">#style/TextAppearance.AppCompat.Title</item>
</style>
windowTitleStyle is important to add as it will give your title that effect that you need.
Now simply use this Theme in your AlertDialog in any activity that you want like below:
AlertDialog.Builder dialog = new AlertDialog.Builder(this, R.style.AlertDialogStyle);
