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

Posted by: admin March 10, 2020 Leave a comment


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) {

        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);
        TextView messageTextView = (TextView)viewDialog.findViewById(R.id.message);



    } }

Creating the dialog:

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

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

Many thanks

How to&Answers:

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() {

                public void onClick(DialogInterface dialogInterface, int i) {


//2. now setup to change color of the button
dialog.setOnShowListener( new OnShowListener() {
    public void onShow(DialogInterface arg0) {


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.


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 name="NegativeButtonStyle" parent="Widget.MaterialComponents.Button.TextButton.Dialog">
    <item name="android:textColor">#f00</item>

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

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 name="NegativeButtonStyle" parent="Widget.AppCompat.Button.ButtonBar.AlertDialog">
    <item name="android:textColor">#f00</item>

<style name="PositiveButtonStyle" parent="Widget.AppCompat.Button.ButtonBar.AlertDialog">
    <item name="android:textColor">#00f</item>

Use your AlertDialogTheme in your AppTheme

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

or in constructor

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


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


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

The result:

Dialog Date picker


The simpliest solution is:

dialog.show(); //Only after .show() was called


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();



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>

And apply the theme in AlertDialog.Builder

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


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 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>

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


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()


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

(Better to use the second one)


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>

and because


was white there… i didn’t see any button text (Dialog buttons are basically buttons too).
there we go, changed it, fixed it.
