How can I change default dialog button text color in android 5

Question

I have many alert dialogs in my app. It is a default layout but I am adding positive and negative buttons to the dialog. So the buttons get the default text color of Android 5 (green). I tried to changed it without success. Any idea how to change that text color?

My Custom dialog:

public class MyCustomDialog extends AlertDialog.Builder { public MyCustomDialog(Context context,String title,String message) { super(context); LayoutInflater inflater = (LayoutInflater) context.getSystemService( Context.LAYOUT_INFLATER_SERVICE ); View viewDialog = inflater.inflate(R.layout.dialog_simple, null, false); TextView titleTextView = (TextView)viewDialog.findViewById(R.id.title); titleTextView.setText(title); TextView messageTextView = (TextView)viewDialog.findViewById(R.id.message); messageTextView.setText(message); this.setCancelable(false); this.setView(viewDialog); } }

Creating the dialog:

MyCustomDialog builder = new MyCustomDialog(getActivity(), "Try Again", errorMessage); builder.setNegativeButton("OK", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialogInterface, int i) { ... } }).show();

That negativeButton is a default dialog button and takes the default green color from Android 5 Lollipop.

Many thanks

Here's a natural way to do it with styles:

If your AppTheme is inherited from Theme.MaterialComponents, then:

<style name="AlertDialogTheme" parent="ThemeOverlay.MaterialComponents.Dialog.Alert"> <item name="buttonBarNegativeButtonStyle">@style/NegativeButtonStyle</item> <item name="buttonBarPositiveButtonStyle">@style/PositiveButtonStyle</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>

If your AppTheme is inherited from Theme.AppCompat:

<style name="AlertDialogTheme" parent="ThemeOverlay.AppCompat.Dialog.Alert"> <item name="buttonBarNegativeButtonStyle">@style/NegativeButtonStyle</item> <item name="buttonBarPositiveButtonStyle">@style/PositiveButtonStyle</item> </style> <style name="NegativeButtonStyle" parent="Widget.AppCompat.Button.ButtonBar.AlertDialog"> <item name="android:textColor">#f00</item> </style> <style name="PositiveButtonStyle" parent="Widget.AppCompat.Button.ButtonBar.AlertDialog"> <item name="android:textColor">#00f</item> </style>

Use your AlertDialogTheme in your AppTheme

<item name="alertDialogTheme">@style/AlertDialogTheme</item>

or in constructor

androidx.appcompat.app.AlertDialog.Builder(context, R.style.AlertDialogTheme)

or If you are using MaterialAlertDialogBuilder then use

<item name="materialAlertDialogTheme">@style/AlertDialogTheme</item>

I had to change buttonBarNegativeButtonStyle to android:buttonBarNegativeButtonStyle and buttonBarPositiveButtonStyle to android:buttonBarPositiveButtonStyle. Then it worked (API 21+).
Remember to use android.support.v7.app.AlertDialog instead of android.app.AlertDialog. Bullshit mistake took me 2 hours
I had to change in AlertDialogTheme's parent to "Base.Theme.AppCompat.Light.Dialog.Alert". And remove buttonBarNegativeButtonStyle & buttonBarPositiveButtonStyle. Also Add in <item name="colorAccent">@color/dashboard_red_color</item> in AlertDialogTheme. nd works perfectly.
This doesn't work when using new material library com.google.android.material:material:1.0.0-beta01 and I am using Theme.MaterialComponents.Light.Dialog.Alert

You can try to create the AlertDialog object first, and then use it to set up to change the color of the button and then show it. (Note that on builder object instead of calling show() we call create() to get the AlertDialog object:

//1. create a dialog object 'dialog' MyCustomDialog builder = new MyCustomDialog(getActivity(), "Try Again", errorMessage); AlertDialog dialog = builder.setNegativeButton("OK", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialogInterface, int i) { ... } }).create(); //2. now setup to change color of the button dialog.setOnShowListener( new OnShowListener() { @Override public void onShow(DialogInterface arg0) { dialog.getButton(AlertDialog.BUTTON_NEGATIVE).setTextColor(COLOR_I_WANT); } }); dialog.show()

The reason you have to do it on onShow() and cannot just get that button after you create your dialog is that the button would not have been created yet.

I changed AlertDialog.BUTTON_POSITIVE to AlertDialog.BUTTON_NEGATIVE to reflect the change in your question. Although it is odd that "OK" button would be a negative button. Usually it is the positive button.

Thanks for you answer, but I dont have that method in AlertDialog. See my updated post.
That method is in AlertDialog class, not Builder class. So instead of calling Builder.show() you can Builder.create(), which returns the AlertDialog class. You then set up the listener and then call show() on the AlertDialog object
But there must be another way to do this. Seems like it's a color from the theme, can we change it through the theme/style?
This is perfect. Just tried in Xamarin.Android and it works perfeclty. Thank you very much.

The color of the buttons and other text can also be changed via theme:

values-21/styles.xml

<style name="AppTheme" parent="..."> ... <item name="android:timePickerDialogTheme">@style/AlertDialogCustom</item> <item name="android:datePickerDialogTheme">@style/AlertDialogCustom</item> <item name="android:alertDialogTheme">@style/AlertDialogCustom</item> </style> <style name="AlertDialogCustom" parent="android:Theme.Material.Light.Dialog.Alert"> <item name="android:colorPrimary">#00397F</item> <item name="android:colorAccent">#0AAEEF</item> </style>

The result:

Dialog Date picker

Currently I don't know a way to change the checkbox color or button color only. The accent color changes them both.

Jon Adams Over a year ago

I liked this approach, but I feel like the answer at stackoverflow.com/a/29810469/2291 is a slightly cleaner way to do it.

To get this to work in my project, I had to remove the android: part from android:alertDialogTheme and from android:colorAccent.

peceps Over a year ago

Having the android: prefix on the values depends on where do you put styles.xml, in values or in values-vXX

Felix Over a year ago

To make this work with AppCompat and a simple values folder, simply follow the changes suggested by @ban-geoengineering

The simpliest solution is:

dialog.show(); //Only after .show() was called dialog.getButton(AlertDialog.BUTTON_NEGATIVE).setTextColor(neededColor); dialog.getButton(AlertDialog.BUTTON_POSITIVE).setTextColor(neededColor);

Those fields should not be referenced from the non-static variable, should be AlertDialog.BUTTON_NEGATIVE etc.

Stephen McCormick Over a year ago

This was the best and simplest way to do this. Note that I did not use the "create" rather grabbed the dialog after the show(). Like AlertDialog dialog = builder.show();

trungdinhtrong Over a year ago

While this solution might work, logically it is flawed. What happen here is you first show the dialog, and then you change its appearance. Depends on the underlying implementation (which could be changed over time) and the performance of the device, you could theoretically see a "flicker" where user see a dialog shows up and then quickly change its appearance.

Hassnain Jamil · Accepted Answer · 2018-04-06 11:00:38Z

There are two ways to change the dialog button color.

Basic Way

If you just want to change in an activity, write the below two lines after alertDialog.show();

alertDialog.getButton(AlertDialog.BUTTON_POSITIVE).setTextColor(getResources().getColor(R.color.colorPrimary)); alertDialog.getButton(AlertDialog.BUTTON_NEGATIVE).setTextColor(getResources().getColor(R.color.colorPrimaryDark));

Recommended

I'll recommend adding a theme for AlertDialog in styles.xml so you don't have to write the same code again and again in each activity/dialog call. You can just create a style and apply that theme on the dialog box. So whenever you want to change the color of AlertDialog box, just change color in styles.xml and all the dialog boxes will be updated in the whole application.

<style name="AlertDialogTheme" parent="Theme.AppCompat.Light.Dialog.Alert"> <item name="colorAccent">@color/colorPrimary</item> </style>

And apply the theme in AlertDialog.Builder

AlertDialog.Builder builder = new AlertDialog.Builder(this, R.style.AlertDialogTheme);

Code on the Rocks · Accepted Answer · 2020-03-10 04:40:38Z

In your app's theme/style, add the following lines:

<item name="android:buttonBarNegativeButtonStyle">@style/NegativeButtonStyle</item> <item name="android:buttonBarPositiveButtonStyle">@style/PositiveButtonStyle</item> <item name="android:buttonBarNeutralButtonStyle">@style/NeutralButtonStyle</item>

Then add the following styles:

<style name="NegativeButtonStyle" parent="Widget.MaterialComponents.Button.TextButton.Dialog"> <item name="android:textColor">@color/red</item> </style> <style name="PositiveButtonStyle" parent="Widget.MaterialComponents.Button.TextButton.Dialog"> <item name="android:textColor">@color/red</item> </style> <style name="NeutralButtonStyle" parent="Widget.MaterialComponents.Button.TextButton.Dialog"> <item name="android:textColor">#00f</item> </style>

Using this method makes it unneccessary to set the theme in the AlertDialog builder.

If you want to change buttons text color (positive, negative, neutral) just add to your custom dialog style:

<item name="colorAccent">@color/accent_color</item>

So, your dialog style must looks like this:

<style name="AlertDialog" parent="Theme.AppCompat.Light.Dialog.Alert"> <item name="android:textColor">@android:color/black</item> <item name="colorAccent">@color/topeka_accent</item> </style>

Kotlin 2020: Very simple method

After dialog.show() use:

dialog.getButton(AlertDialog.BUTTON_NEGATIVE).setTextColor(ContextCompat.getColor(requireContext(), R.color.yourColor))

Mr T · Accepted Answer · 2020-04-23 15:30:15Z

Here is how you do it: Simple way

// Initializing a new alert dialog AlertDialog.Builder builder = new AlertDialog.Builder(getActivity()); builder.setMessage(R.string.message); builder.setPositiveButton(R.string.ok, new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { doAction(); } }); builder.setNegativeButton(R.string.cancel, null); // Create the alert dialog and change Buttons colour AlertDialog dialog = builder.create(); dialog.setOnShowListener(new DialogInterface.OnShowListener() { @Override public void onShow(DialogInterface arg0) { dialog.getButton(AlertDialog.BUTTON_POSITIVE).setTextColor(getResources().getColor(R.color.red)); dialog.getButton(AlertDialog.BUTTON_NEGATIVE).setTextColor(getResources().getColor(R.color.blue)); //dialog.getButton(AlertDialog.BUTTON_NEUTRAL).setTextColor(getResources().getColor(R.color.black)); } }); dialog.show();

Ramakrishna Joshi · Accepted Answer · 2022-04-20 11:36:20Z

We can create extension function and call the extension function after dialog.show() to customise Alert Dialog button colors.

fun AlertDialog.makeButtonTextBlue() { this.getButton(AlertDialog.BUTTON_POSITIVE).setTextColor(ContextCompat.getColor(context, R.color.blue)) this.getButton(AlertDialog.BUTTON_NEGATIVE).setTextColor(ContextCompat.getColor(context, R.color.blue)) }

Usage:

dialog.show() dialog.makeButtonTextBlue()

<style name="AlertDialogCustom" parent="Theme.AppCompat.Light.Dialog.Alert"> <item name="android:colorPrimary">#00397F</item> <item name="android:textColorPrimary">#22397F</item> <item name="android:colorAccent">#00397F</item> <item name="colorPrimaryDark">#22397F</item> </style>

The color of the buttons and other text can also be changed using appcompat :

Theme.AppCompat.Light.Dialog.Alert works nicely to change button color to white.

shah0651 · Accepted Answer · 2020-12-24 20:59:23Z

Using styles.xml (value)

Very Easy solution , change colorPrimary as your choice and it will change color of button text of alert box.

<style name="MyAlertDialogStyle" parent="android:Theme.Material.Dialog.Alert"> <!-- Used for the buttons --> <item name="colorAccent">@android:color/white</item> <!-- Used for the title and text --> <item name="android:textColorPrimary">@color/black</item> <!-- Used for the background --> <item name="android:background">#ffffff</item> <item name="android:colorPrimary">@color/white</item> <item name="android:colorAccent">@color/white</item> <item name="android:windowEnterAnimation">@anim/bottom_left_enter</item> </style>

Alternative (Using Java)

 @SuppressLint("ResourceAsColor") public boolean onJsAlert(WebView view, String url, String message, final JsResult result) { AlertDialog dialog = new AlertDialog.Builder(view.getContext(), R.style.MyAlertDialogStyle) .setTitle("Royal Frolics") .setIcon(R.mipmap.ic_launcher) .setMessage(message) .setPositiveButton("OK", (dialog1, which) -> { //do nothing result.confirm(); }).create(); Objects.requireNonNull(dialog.getWindow()).getAttributes().windowAnimations = R.style.MyAlertDialogStyle; dialog.show(); dialog.getButton(AlertDialog.BUTTON_POSITIVE).setTextColor(R.color.white); return true; }

Just as a side note:

The colors of the buttons (and the whole style) also depend on the current theme which can be rather different when you use either

android.app.AlertDialog.Builder builder = new AlertDialog.Builder()

or

android.support.v7.app.AlertDialog.Builder builder = new AlertDialog.Builder()

(Better to use the second one)

Anh Duy · Accepted Answer · 2022-01-20 15:47:43Z

This is a custom theme to change textColor of buttons on AlertDialog. It works on my device - SamsungA70 - android 11

<style name="AlertDialogCustom" parent="Theme.AppCompat.Light.Dialog.Alert"> <!--Support for other devices, I think so--> <item name="android:textColor">@color/yourcolor</item> <item name="colorButtonNormal">@color/yourcolor</item> <item name="colorAccent">@color/yourcolor</item> <!--only this code works on my device--> <item name="buttonBarButtonStyle">@style/MyButtonStyle</item> </style> <!--only this code works on my device--> <style name="MyButtonStyle" parent="Widget.AppCompat.Button.Borderless"> <item name="android:textColor">@color/yourcolor</item> </style>

arlomedia · Accepted Answer · 2022-10-27 20:56:29Z

Here's a Kotlin version of the accepted answer from @trungdinhtrong:

val alert = builder.create() if (button1Text == "Delete") { alert.setOnShowListener { dialog -> alert.getButton(AlertDialog.BUTTON_POSITIVE).setTextColor(Color.RED); } }

BTW, it seems like Android's idea of "positive" and "negative" buttons isn't compatible with the idea of "safe" and "destructive" buttons. In a dialog with Cancel and Delete buttons, I think Android would consider Delete the positive button because it performs an action, but I would consider it a destructive button because it leads to data loss. So instead of using the styles file to set positive and negative button colors, I'm using this code to make the Delete button red even though it's the "positive" button.

I have tried several solutions but none of them worked except this one.

Manaus · Accepted Answer · 2020-08-14 15:03:24Z

For me it was different, I used a button theme

<style name="ButtonLight_pink" parent="android:Widget.Button"> <item name="android:background">@drawable/light_pink_btn_default_holo_light</item> <item name="android:minHeight">48dip</item> <item name="android:minWidth">64dip</item> <item name="android:textColor">@color/tab_background_light_pink</item> </style>

and because android:textColor was white there… I didn't see any button text (Dialog buttons are basically buttons too). There we go, changed it, fixed it.

GotDots · Accepted Answer · 2022-06-18 20:25:08Z

Looked a lot at styling again while learning a lot. One critical thing to know is that code is a higher order than styling. The styling just wasn't working for the buttons so I thank Ramakrishna Joshi for his answer in this post. I added to it to show in both day and night themes:

private fun AlertDialog.dlgTextColor() { val currentNightMode = (resources.configuration.uiMode and Configuration.UI_MODE_NIGHT_MASK) when (currentNightMode) { Configuration.UI_MODE_NIGHT_YES -> { this.getButton(AlertDialog.BUTTON_POSITIVE).setTextColor(ContextCompat.getColor(context, R.color.yellow_accent)) this.getButton(AlertDialog.BUTTON_NEGATIVE).setTextColor(ContextCompat.getColor(context, R.color.yellow_accent)) } Configuration.UI_MODE_NIGHT_NO -> { this.getButton(AlertDialog.BUTTON_POSITIVE).setTextColor(ContextCompat.getColor(context, R.color.blue_accent)) this.getButton(AlertDialog.BUTTON_NEGATIVE).setTextColor(ContextCompat.getColor(context, R.color.blue_accent)) } } }

and the call to it is:

.dlgTextColor()

And the call to the method does follow .show in the dialog builder.

Change the colorAccent color in res/values/colors.xml, the color is expressed in hexadecimal, for example #010613 is black.
