How can I change default dialog button text color?

How can I change the default text and background color of Dialog buttons (setPositiveButton, setNeutralButton)?
public void onBackPressed(){
if(webView.canGoBack()) {
webView.goBack();
}else{
AlertDialog.Builder dialog = new AlertDialog.Builder(this);
dialog.create();
dialog.setTitle("Confirmation ...");
dialog.setMessage("Are you sure ! \nYou want to exit from app ?");
dialog.setCancelable(false);
dialog.setPositiveButton("Yes", (dialogInterface, which) -> finish());
dialog.setNeutralButton("Cancel", MainActivity::onClick);
dialog.show();
}
}

If your AppTheme is inherited from Theme.AppCompat:
<style name="AlertDialogTheme" parent="ThemeOverlay.AppCompat.Dialog.Alert">
<item name="buttonBarPositiveButtonStyle">#style/PositiveButtonStyle</item>
<item name="buttonBarNeutralButtonStyle">#style/NeutralButtonStyle</item>
</style>
<style name="PositiveButtonStyle" parent="Widget.AppCompat.Button.ButtonBar.AlertDialog">
<item name="android:textColor">#FFFFFF</item>
<item name="android:background">#F44336</item>
<item name="android:width">90dp</item>
<item name="android:padding">0px</item>
</style>
<style name="NeutralButtonStyle" parent="Widget.AppCompat.Button.ButtonBar.AlertDialog">
<item name="android:textColor">#F44336</item>
<item name="android:background">#FFEB3B</item>
<item name="android:width">90dp</item>
</style>
Use your AlertDialogTheme in your AppTheme
<item name="alertDialogTheme">#style/AlertDialogTheme</item>

Alert dialog theme does not inherit `windowBackground` from activity theme

In my app I have this theme in the styles.xml
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#000000</item>
<item name="colorAccent">#color/neon_green</item>
<item name="android:windowBackground">#color/black_17</item>
</style>
but the attribute windowBackground does not cause the dialog background to change. The dialog background color is still white. The neon_green highlight color does appear for the dialog text though.
Only the background color that does not change.
AlertDialog.Builder builder =
new AlertDialog.Builder(new ContextThemeWrapper(act, R.style.AppTheme));
builder.setMessage("text")
.setPositiveButton("pos ", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
// FIRE ZE MISSILES!
}
})
.setNegativeButton("neg", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
// User cancelled the dialog
}
});
builder.create().show();

I just added this to my styles
<style name="AppCompatAlertDialogStyle" parent="Theme.AppCompat.Light.Dialog.Alert">
<item name="android:textColor">#color/white</item>
<item name="android:textColorPrimary">#color/white</item>
<item name="android:background">#color/black_17</item>
</style>
then I passed the styles to the builder
AlertDialog.Builder builder =
new AlertDialog.Builder(act,
R.style.AppCompatAlertDialogStyle);

Appcompat Alert Dialog Action button background On pressed state

I am trying new AlertDialog from appcompat v7 22.1.1.
It works pretty well (In all android versions) as in image.
Style for AlertDialog is this. (For now I am using hardcoded color values instead of color resources)
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorPrimaryDark">#111111</item>
<item name="colorPrimary">#00ddff</item>
<item name="colorAccent">#0044aa</item>
<item name="colorButtonNormal">#00aaaa</item>
<item name="colorControlHighlight">#00ddff</item>
<item name="alertDialogTheme">#style/AlertDialogTheme</item>
</style>
<style name="AlertDialogTheme" parent="Theme.AppCompat.Dialog.Alert">
<item name="colorAccent">#0044aa</item>
<item name="android:background">#ffffff</item>
<item name="android:textColorPrimary">#000000</item>
<item name="android:windowTitleStyle">#style/MyTitleTextStyle</item>
</style>
<style name="MyTitleTextStyle">
<item name="android:textColor">#0044aa</item>
<item name="android:textAppearance">#style/TextAppearance.AppCompat.Title</item>
</style>
My question is ,
1) how to change statePressed color which is rounded (Gray) in the image ?
2) No pressed color is there in android >= 21 , what is hack for this ?
3) How can I have different colors of action buttons (Is it possible)?
Any help would be great.

You can use style attributes like
buttonBarButtonStyle
buttonBarNegativeButtonStyle
buttonBarNeutralButtonStyle
buttonBarPositiveButtonStyle
Example:
<style name="dialog_theme" parent="Theme.AppCompat.Dialog.Alert">
<item name="buttonBarNegativeButtonStyle">#style/dialog_button.negative</item>
<item name="buttonBarPositiveButtonStyle">#style/dialog_button.positive</item>
</style>
<style name="dialog_button">
<item name="android:textStyle">bold</item>
<item name="android:minWidth">64dp</item>
<item name="android:paddingLeft">8dp</item>
<item name="android:paddingRight">8dp</item>
<item name="android:background">#drawable/dialogButtonSelector</item>
</style>
<style name="dialog_button.negative">
<item name="android:textColor">#f00</item>
</style>
<style name="dialog_button.positive">
<item name="android:layout_marginLeft">8dp</item>
<item name="android:textColor">#00f</item>
</style>
Where dialogButtonSelector is our custom drawable selector.
Unfortunatelly setting background on dialog_button destroy our paddings and margins so I need to set it again.
dialog_button style can inherit through Widget.AppCompat.Button.ButtonBar.AlertDialog but I found that it has missing styles like textStyle bold.

I have the Answer for the 3rd Questions
( How can I have different colors of action buttons (Is it possible)? )
Code:
// Initialize AlertDialog & AlertDialog Builder
AlertDialog.Builder builder = new AlertDialog.Builder(YourActivity.this);
builder.setTitle("AlertDialog Title");
...........
.........
//Build your AlertDialog
AlertDialog Demo_alertDialog= builder.create();
Demo_alertDialog.show();
//For Positive Button:
Button b_pos;
b_pos=Demo_alertDialog.getButton(DialogInterface.BUTTON_POSITIVE);
if(b_pos!=null){
b_pos.setTextColor(getResources().getColor(R.color.YourColor));
}
//For Neutral Button:
Button b_neu;
b_neu=Demo_alertDialog.getButton(DialogInterface.BUTTON_NEUTRAL);
if(b_neu!=null){
b_neu.setTextColor(getResources().getColor(R.color.YourColor));
}
//For Negative Button:
Button b_neg;
b_neg=Demo_alertDialog.getButton(DialogInterface.BUTTON_NEGATIVE);
if(b_neg!=null){
b_neg.setTextColor(getResources().getColor(R.color.YourColor));
}
Happy Coding :)

AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this); builder.setMessage("Title"); builder.setCancelable(true);
builder.setPositiveButton("OK",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
builder.setNegativeButton("Cancel",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
AlertDialog alertdialog = builder.create();
alertdialog.show();
Button nbutton = alertdialog.getButton(DialogInterface.BUTTON_NEGATIVE);
nbutton.setBackground(getResources().getDrawable(R.drawable.btn_press_white_rect));
Button pbutton = alertdialog.getButton(DialogInterface.BUTTON_POSITIVE);
pbutton.setBackground(getResources().getDrawable(R.drawable.btn_press_white_rect));
**btn_press_white_rect.xml**
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:drawable="#drawable/rounded_rect_yellow" ></item>
<item android:state_pressed="false" android:drawable="#drawable/rounded_rect_white" ></item>
</selector>

Set typeface with custom font for alert dialog items

I'm creating an alert dialog this way:
AlertDialog.Builder alertDialog = new AlertDialog.Builder(view.getContext());
alertDialog.setCustomTitle(null);
alertDialog.setItems(getAllListNames(), new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
//Doing something awesome...
}
});
I know it creates a list view with my items, I want to set a typeface with a custom font for them and also set a max number of characters for each list item, how can I do it?

You have to create a custom theme. Here is the official guide: http://developer.android.com/guide/topics/ui/themes.html :)
Something like this (in the style.xml file):
<style name="CustomFontTheme" parent="android:Theme.Light">
<item name="android:textViewStyle">#style/MyTextViewStyle</item>
<item name="android:buttonStyle">#style/MyButtonStyle</item>
</style>
<style name="MyTextViewStyle" parent="android:Widget.TextView">
<item name="android:fontFamily">sans-serif-light</item>
</style>
<style name="MyButtonStyle" parent="android:Widget.Holo.Button">
<item name="android:fontFamily">sans-serif-light</item>
</style>
Then when you create the dialog you can do this:
Context context = new ContextThemeWrapper(view.getContext(), R.style.CustomFontTheme)
AlertDialog.Builder alertDialog = new AlertDialog.Builder(context);
Where R.style.CustomFontTheme is the id for the them you have created.
Update:
Ok, to add your custom typeface you can follow this gist:
https://gist.github.com/artem-zinnatullin/7749076
The key is to override the a given font face when the application starts like this:
TypefaceUtil.overrideFont(getApplicationContext(), "AWESOME-FONT", "fonts/Awesome-Font.ttf");
the gist has the implementation for that method.
So the theme styles should look like this now:
<style name="MyTextViewStyle" parent="android:Widget.TextView">
<item name="android:fontFamily">awesome-font</item>
</style>
<style name="MyButtonStyle" parent="android:Widget.Holo.Button">
<item name="android:fontFamily">awesome-font</item>
</style>
