Here is how I did.

AlertDialog.Builder customBuilder = new AlertDialog.Builder(new ContextThemeWrapper(this,android.R.style.Theme_Dialog));

customBuilder.setTitle(R.string.popup_error_title);
customBuilder.setNegativeButton("Exit application", new DialogInterface.OnClickListener() {  
    public void onClick(DialogInterface dialog, int which) {  
        MyActivity.this.finish();
    }  
});

AlertDialog dialog = customBuilder.create();
dialog.show();

Button b = dialog.getButton(DialogInterface.BUTTON_NEGATIVE);

if(b != null) {
    b.setBackgroundDrawable(getResources().getDrawable(R.drawable.my_button));
}

I find the drawable here

    setBackgroundDrawable(Drawable) is deprecated in API level 16; better to use setBackground(Drawable) if you are not targeting below API level 16.

Since most people are probably using a DialogFragment by now I ran into some issues and clicked my way through several SO answers to solve those. Let me post my current solution.

I ended up setting the button-background with custom drawables as already suggested several times. However, this was not yet possible in the onCreateDialog-method of the DialogFragment. You can either do this e.g. in onStart(), or (which is what I preferred) in the onShow-listener of the dialog! Keep in mind though, you need to invalidate your buttons after the changes then.

As for the margins: simple remove the padding in your Drawable-XML for the buttons.

#onCreateDialog in your DialogFragment:

@Override
public Dialog onCreateDialog(final Bundle savedInstanceState) {
  AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());

  // setup your dialog here...

  builder.setNegativeButton(getString(R.string.cancel), new DialogInterface.OnClickListener() {
    @Override
    public void onClick(final DialogInterface dialog, final int which) {
      // do something
    }
  });

  builder.setPositiveButton(getString(R.string.ok), new DialogInterface.OnClickListener() {
    @Override
    public void onClick(final DialogInterface dialog, final int which) {
      // do something
    }
  });

  final AlertDialog dialog = builder.create();

  dialog.setOnShowListener(new DialogInterface.OnShowListener() {
    @Override
    public void onShow(final DialogInterface dialog) {
      Button negativeButton = ((AlertDialog)dialog).getButton(DialogInterface.BUTTON_NEGATIVE);
      Button positiveButton = ((AlertDialog)dialog).getButton(DialogInterface.BUTTON_POSITIVE);

      // this not working because multiplying white background (e.g. Holo Light) has no effect
      //negativeButton.getBackground().setColorFilter(0xFFFF0000, PorterDuff.Mode.MULTIPLY);

      final Drawable negativeButtonDrawable = getResources().getDrawable(R.drawable.alert_dialog_button_light_red);
      final Drawable positiveButtonDrawable = getResources().getDrawable(R.drawable.alert_dialog_button_light_green);
      if (Build.VERSION.SDK_INT >= 16) {
        negativeButton.setBackground(negativeButtonDrawable);
        positiveButton.setBackground(positiveButtonDrawable);
      } else {
        negativeButton.setBackgroundDrawable(negativeButtonDrawable);
        positiveButton.setBackgroundDrawable(positiveButtonDrawable);
      }

      negativeButton.invalidate();
      positiveButton.invalidate();
    }
  });

  return dialog;
}

Drawable-XML example for a button:

<?xml version="1.0" encoding="utf-8"?>
<selector
  xmlns:android="http://schemas.android.com/apk/res/android">

  <item android:state_pressed="true" >
    <shape>
      <gradient
        android:startColor="@color/alert_dialog_button_green_pressed1"
        android:endColor="@color/alert_dialog_button_green_pressed2"
        android:angle="270" />
    </shape>
  </item>

  <item android:state_focused="true" >
    <shape>
      <gradient
        android:endColor="@color/alert_dialog_button_green_focused1"
        android:startColor="@color/alert_dialog_button_green_focused2"
        android:angle="270" />
    </shape>
  </item>

  <item>
    <shape>
      <gradient
        android:endColor="@color/alert_dialog_button_green1"
        android:startColor="@color/alert_dialog_button_green2"
        android:angle="270" />
    </shape>
  </item>
</selector>

Don't forget to define your colors in the res\values\colors.xml, e.g. like this (I didn't want a gradient, therefore colors 1 & 2 are the same):

<?xml version="1.0" encoding="utf-8"?>
<resources>
  <color name="alert_dialog_button_green1">#b4099930</color>
  <color name="alert_dialog_button_green2">#b4099930</color>
  <color name="alert_dialog_button_green_focused1">#96099930</color>
  <color name="alert_dialog_button_green_focused2">#96099930</color>
  <color name="alert_dialog_button_green_pressed1">#96099930</color>
  <color name="alert_dialog_button_green_pressed2">#96099930</color>
</resources>

I have done by this code it might help you:

AlertDialog.Builder builder1 = new AlertDialog.Builder(this); 
        builder1.setCancelable(true);
     builder1.setTitle("abc");
      builder1.setMessage("abcdefg");
      builder1.setInverseBackgroundForced(true);
     builder1.setPositiveButton("Yes",
             new DialogInterface.OnClickListener() {
         public void onClick(DialogInterface dialog, int id) {
             dialog.cancel();
         }
     }); 

     builder1.setNegativeButton("No",
             new DialogInterface.OnClickListener() {
         public void onClick(DialogInterface dialog, int id) {
             dialog.cancel();
         }
     });

     AlertDialog alert11 = builder1.create();
     alert11.show(); 

     Button buttonbackground = alert11.getButton(DialogInterface.BUTTON_NEGATIVE); 
     buttonbackground.setBackgroundColor(Color.BLUE); 

     Button buttonbackground1 = alert11.getButton(DialogInterface.BUTTON_POSITIVE);

I wanted to solve this with themes rather than extra code since it feels cleaner to me to have all the styling-related stuff in the styles.xml. What I did was based on Arade's answer and this other question:

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

This will change the color of the button text of any alert dialog you create with style AlertDialogDanger. To do so:

    new AlertDialog.Builder(new ContextThemeWrapper(this, R.style.AlertDialogDanger))
            .setMessage("Really delete?")
            .setPositiveButton("Delete", null)
            .setNegativeButton("Cancel", null)
            .create().show();

we can change alert dialog button text colour using Style.

 AlertDialog.Builder dialog = new AlertDialog.Builder(context, R.style.yourDialog);
    dialog.setTitle(R.string.title);
    dialog.setNegativeButton(R.string.no, new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialogInterface, int i) {
            //code here 
        }
    });
    dialog.setPositiveButton(R.string.yes, new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialogInterface, int i) {
            //do here 
        }
    });

    dialog.show();

Style.xml

<style name="yourDialog" parent="Theme.AppCompat.Light.Dialog.Alert">

    <item name="android:colorAccent">@color/themeColor</item>
    <item name="android:colorPrimary">@color/themeColor</item>

There are 2 ways to do it:

  1. Via code:
        val builder = AlertDialog.Builder(activity!!)
        ...
        val dialog = builder.create()
                .apply {
                    setOnShowListener {
                        getButton(Dialog.BUTTON_NEGATIVE)?.setTextColor(...)
                    }
                }
  1. Via XML :
    <style name="AppTheme" parent="Theme.MaterialComponents.Light.DarkActionBar">
        ...
        <item name="materialAlertDialogTheme">@style/ThemeOverlay.MyApp.MaterialAlertDialog</item>
    </style>

    <style name="ThemeOverlay.MyApp.MaterialAlertDialog" parent="ThemeOverlay.MaterialComponents.MaterialAlertDialog">
        <item name="dialogCornerRadius">6dp</item>
        <item name="buttonBarNegativeButtonStyle">@style/Widget.MyApp.NegativeButton</item>
        <item name="buttonBarPositiveButtonStyle">@style/Widget.MyApp.PositiveButton</item>
    </style>

    <style name="Widget.MyApp.NegativeButton" parent="Widget.MaterialComponents.Button.TextButton.Dialog">
        <item name="materialThemeOverlay">@style/ThemeOverlay.MyApp.NegativeButton</item>
    </style>

    <style name="Widget.MyApp.PositiveButton" parent="Widget.MaterialComponents.Button.TextButton.Dialog">
        <item name="materialThemeOverlay">@style/ThemeOverlay.MyApp.PositiveButton</item>
    </style>

    <style name="ThemeOverlay.MyApp.NegativeButton" parent="">
        <item name="colorPrimary">#f00</item>
    </style>

    <style name="ThemeOverlay.MyApp.PositiveButton" parent="">
        <item name="colorPrimary">#00f</item>
    </style>

usage:

AlertDialog.Builder(this).setTitle("title").setMessage("message").setPositiveButton("positive", null)
                .setNegativeButton("negative", null).show()

Or, if you don't want to have the style as default:

AlertDialog.Builder(this, R.style.ThemeOverlay_MyApp_MaterialAlertDialog).setTitle("title")
            .setMessage("message").setPositiveButton("positive", null)
            .setNegativeButton("negative", null).show()

Maybe someone already answers this way but in my eye, I didn't found so I prefer this answer that is working great. Remember setTextColor should be applied after dialog.show() otherwise i

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

    dialog.getButton(AlertDialog.BUTTON_NEGATIVE).setTextColor(neededColor);
    dialog.getButton(AlertDialog.BUTTON_POSITIVE).setTextColor(neededColor);

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

<style name="AlertDialogCustom" parent="Theme.AppCompat.Light.Dialog.Alert">
    <item name="android:colorPrimary">@color/flexdrive_blue_1</item>
    <item name="android:textColorPrimary">@color/flexdrive_blue_6</item>
    <item name="android:colorAccent">@color/flexdrive_blue_1</item>
    <item name="colorPrimaryDark">@color/flexdrive_blue_4</item>

I think there are developer who wish to extend the AlertDialog class and define the buttons colors withing class definition. For such purpose you can use this code:

class MyDialog extends AlertDialog {
    public MyDialog(final Context context) {
        super(context); 
        setOnShowListener(new OnShowListener() {
            @Override
            public void onShow(DialogInterface dialog) {
                Button negativeButton = getButton(DialogInterface.BUTTON_NEGATIVE);  
                Button positiveButton = getButton(DialogInterface.BUTTON_POSITIVE);

                negativeButton.setBackgroundColor(Color.GREEN);
                positiveButton.setBackgroundColor(Color.RED);
            }
        });
    }
}

Here is the perfect solution that worked for me:

alertDialogBuilder.setTitle("");
alertDialogBuilder.setMessage("Are you sure you want to Logout?");

alertDialogBuilder.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialogInterface, int i) {
        preferenceManager.logout();
        Intent intent = new Intent(DashboardActivity.this,
                                LoginActivity.class);
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK
                                | Intent.FLAG_ACTIVITY_CLEAR_TASK);
        startActivity(intent);
    }
});

alertDialogBuilder.setNegativeButton("Cancel", null);

AlertDialog alertDialog = alertDialogBuilder.create();
alertDialog.show();

Button btnOk = alertDialog.getButton(DialogInterface.BUTTON_POSITIVE);
Button btnCancel = alertDialog.getButton(DialogInterface.BUTTON_NEGATIVE);

if (btnOk != null && btnCancel != null) {       
    btnOk.setTextColor(getResources().getColor(R.color.colorGreenButton));
    btnCancel.setTextColor(getResources().getColor(R.color.colorGreenButton));
} else {
    Log.i(TAG, "LogOut: Buttons of Dialog are null");

if you are using DialogFragment ( android.app.DialogFragment ) then you can overwrite onStart method to get handle of all the buttons (Positive, Negative and Neutral).

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
    View eventEditDialogView = View.inflate(this.getActivity(), R.layout.event_edit_dialog,
                                            null);

    builder.setTitle(getLocalizedString("edit_event"))
            .setView(eventEditDialogView)
            .setPositiveButton(getLocalizedString("all_events"), new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int id) {
                }
            })
            .setNegativeButton(getLocalizedString("this_event"), new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
                }
            })
    return builder.create();
}

 @Override
    public void onStart() {
        super.onStart();
    Button positive = ((AlertDialog) getDialog()).getButton(AlertDialog.BUTTON_POSITIVE);
    positive.setTextColor(Color.BLACK);
    positive.setBackgroundColor(getResources().getColor(R.color.GrayBGColor));
}

All the above solutions will work with AlertDialog or Dialog created on same activity or Fragment but not on DialogFragment created separately.

no you cant change the color or images or background of the default buttons of alert boxes. For customization you will need to make you on custom dialog box like this. 

public class TryAgainAlert extends Dialog implements OnClickListener
{
    @Override
 public boolean onKeyDown(int keyCode, KeyEvent event)
 {
  if (keyCode == KeyEvent.KEYCODE_BACK)
  {   

   Intent i = new Intent(getApplicationContext(), MainMenu.class);
   finish();
   startActivity(i);

   return true;
  }
  return super.onKeyDown(keyCode, event);
 }


    TextView scores;
    Button tryagain,mainmenu,submit;


     public TryAgainAlert(Context context) {
        super(context);

        setContentView(R.layout.tryagainalert);

        scores=(TextView)findViewById(R.id.text);



        tryagain= (Button) findViewById(R.id.trya);
        mainmenu= (Button) findViewById(R.id.submitscore);
        submit= (Button) findViewById(R.id.mainmenu);

    }


    @Override
    public void onClick(View v) {
        if(v == tryagain)
        {

        else if (v==mainmenu)
        {


        }
        else if (v == submit)
        {

        }
    }

}

you can do what ever you want with the XML file. I hope it will help. Thanks

builder.setMessage(R.string.message);
builder.setPositiveButton(R.string.ok, new DialogInterface.OnClickListener() {

        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));

simply make string Spannable and pass it to setPositveButton or negative button like this

val n=getString(R.string.reject).toSpannable() n.setSpan(ForegroundColorSpan(Color.RED),0,6,Spanned.SPAN_EXCLUSIVE_EXCLUSIVE) n.setNegativeButton(n)

Are you referring to the neutral, positive and negative buttons? Or to buttons you included in the layout?

If you are referring to the former, then yes you can. Check out the Custom Button section in this tutorial. You basically need an XML file that will tell your button which drawable/color to use for each state change. You can then set this XML file as your button's background.
