I've used MaterialDatePicker for the purpose of selecting a single date & also I had achieved that task but I cannot change the theme of the header & button.
MaterialDatePicker.Builder builder;
MaterialDatePicker materialDatePicker;
long today = MaterialDatePicker.todayInUtcMilliseconds();
CalendarConstraints.Builder con = new CalendarConstraints.Builder();
con.setValidator(DateValidatorPointForward.now());
builder.setSelection(today);
builder.setCalendarConstraints(con.build());
materialDatePicker = builder.build();
findViewById(R.id.startCalender).setOnClickListener(v ->
materialDatePicker.show(getSupportFragmentManager(), builder.toString())
);
materialDatePicker.addOnPositiveButtonClickListener(selection ->
Toast.makeText(this, materialDatePicker.getHeaderText(),
Toast.LENGTH_SHORT).show());
You have different options.
You can use:
builder.setTheme(R.style.MaterialCalendarTheme);
with:
<style name="MaterialCalendarTheme" parent="ThemeOverlay.MaterialComponents.MaterialCalendar">
<!-- just override the colors used in the default style -->
<item name="colorOnPrimary">#color/primaryDarkColor</item>
<item name="colorPrimary">#color/primaryLightColor</item>
</style>
or you can use something like:
<style name="MaterialCalendarTheme" parent="ThemeOverlay.MaterialComponents.MaterialCalendar">
<!-- Header panel -->
<item name="materialCalendarHeaderLayout">#style/MaterialCalendar.HeaderLayout1</item>
<!-- Buttons -->
<item name="buttonBarPositiveButtonStyle">#style/TextButton.Dialog1</item>
<item name="buttonBarNegativeButtonStyle">#style/TextButton.Dialog1</item>
</style>
<style name="MaterialCalendar.HeaderLayout1" parent="Widget.MaterialComponents.MaterialCalendar.HeaderLayout">
<!--<item name="android:background">?attr/colorPrimary</item>-->
<item name="android:background">#color/primaryLightColor</item>
</style>
<style name="TextButton.Dialog1" parent="Widget.MaterialComponents.Button.TextButton.Dialog">
<item name="android:textColor">#color/white</item>
<item name="backgroundTint">#color/primaryDarkColor</item>
</style>
hello, I have an alert dialog. the buttons are purple. yes I can change the color of the text inside using:
alertDialog.getButton(Dialog.BUTTON_NEGATIVE).
setTextColor(Color.parseColor("#000000"));
however when they are touched, there is a purple hue that forms.
I want the hue to be blue like the main accent of my app and the text to be black.
this is my alert style:
<style name="MyCustomAlert2" parent="Theme.MaterialComponents.Dialog.Alert">
<item name="colorAccent">#color/materialBlue</item>
<item name="android:textColorPrimary">#android:color/black</item>
<item name="android:windowBackground">#drawable/custom_alert2</item>
<item name="colorControlNormal">#android:color/black</item>
<item name="colorControlActivated">#color/materialBlue</item>
<item name="textColorAlertDialogListItem">#android:color/black</item>
</style>
note: none of the colors linked above are purple.
thanks for the help
Use new theandroidx.appcompat.app.AlertDialog and the Material components for android library.
Just use something like:
new MaterialAlertDialogBuilder(context)
.setTitle("...")
.setMessage("....")
.setPositiveButton("Ok", /* listener = */ null)
.setNegativeButton("Cancel", /* listener = */ null)
.show();
Then you can customize the style with something like:
<!-- Alert Dialog -->
<style name="MyThemeOverlay.MaterialComponents.MaterialAlertDialog" parent="#style/ThemeOverlay.MaterialComponents.MaterialAlertDialog">
<item name="buttonBarPositiveButtonStyle">#style/PositiveButtonStyle</item>
<item name="buttonBarNegativeButtonStyle">#style/Widget.MaterialComponents.Button.TextButton.Dialog</item>
</style>
and here you can change each button:
<style name="PositiveButtonStyle" parent="Widget.MaterialComponents.Button.TextButton.Dialog">
<item name="android:textColor">#000000</item>
<item name="backgroundTint">#color/selector_bt</item>
</style>
You can set the style globally in your app theme using:
<item name="materialAlertDialogTheme">#style/MyThemeOverlay.MaterialComponents.MaterialAlertDialog</item>
or you can use the constructor:
new MaterialAlertDialogBuilder(context,
R.style.MyThemeOverlay_MaterialComponents_MaterialAlertDialog)
I try to use widgets from Material Components only, but in many cases, it's not documented how styling can be achieved.
Let's consider MaterialAlertDialog.
Each time I want to show a dialog, I call such part of the code:
MaterialAlertDialogBuilder(context, R.style.Theme_MyApp_Dialog_Alert)
.setTitle("Title")
.setMessage("This is message.")
.setPositiveButton(R.string.ok) { _, _ -> }
.show()
As you can see, I'm using a custom theme.
<style name="Theme.MyApp.Dialog.Alert" parent="ThemeOverlay.MaterialComponents.MaterialAlertDialog">
<!-- attributes here -->
</style>
The problem is that some of the attributes are not working. For example textColor. So the question is how to change the body or title text color in MaterialAlertDialog?
I use the newest version of Material Components - 1.1.0-alpha07.
PS.
I'm not sure which theme should be a parent. In Material Theme Builder they use #style/ThemeOverlay.MaterialComponents.Dialog.Alert which actually gives an "old" look of dialogs.
Change the style as below
<style name="Theme.MyApp.Dialog.Alert" parent="ThemeOverlay.MaterialComponents.MaterialAlertDialog">
<item name="materialAlertDialogTitleTextStyle">#style/MaterialAlertDialogText</item>
</style>
Create MaterialAlertDialogText style and set textColor
<style name="MaterialAlertDialogText" parent="#style/MaterialAlertDialog.MaterialComponents.Title.Text">
<item name="android:textColor">#color/yourTextColor</item>
</style>
You can simply override the default colors using:
<style name="Theme.MyApp.Dialog.Alert" parent="#style/ThemeOverlay.MaterialComponents.MaterialAlertDialog">
<!-- Text Color for title and message -->
<item name="colorOnSurface">#color/....</item>
....
</style>
Otherwise you can customize the style used by the title and the body text using:
<style name="Theme.MyApp.Dialog.Alert" parent="#style/ThemeOverlay.MaterialComponents.MaterialAlertDialog">
<!-- Title -->
<item name="materialAlertDialogTitleTextStyle">#style/MyTitle_MaterialAlertDialog.MaterialComponents.Title.Text</item>
<!-- Body -->
<item name="materialAlertDialogBodyTextStyle">#style/BodyTextAppearance.MaterialComponents.Body2</item>
</style>
<style name="MyTitle_MaterialAlertDialog.MaterialComponents.Title.Text" parent="#style/MaterialAlertDialog.MaterialComponents.Title.Text">
<item name="android:textColor">#color/...</item>
<item name="android:textAppearance">#style/....</item>
</style>
<style name="BodyTextAppearance.MaterialComponents.Body2" parent="#style/MaterialAlertDialog.MaterialComponents.Body.Text">
<item name="android:textColor">#color/....</item>
<item name="android:textSize">20sp</item>
<item name="android:textStyle">bold</item>
<item name="android:textAllCaps">true</item>
<item name="fontFamily">sans-serif-condensed-light</item>
</style>
I've created a Dialog using below code in android.
final CharSequence[] ss = {"1", "2", "3", "4"};
AlertDialog.Builder builder = new AlertDialog.Builder(context, R.style.MyAlertDialogStyle);
builder.setTitle("title");
builder.setItems(ss, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
}
});
builder.show();
This is MyAlertDialogStyle.xml.
<style name="MyAlertDialogStyle" parent="Theme.AppCompat.Light.Dialog.Alert">
<item name="colorAccent">#color/red</item>
<item name="android:textColorPrimary">#color/black</item>
<item name="android:background">#color/background</item>
<item name="android:windowMinWidthMajor">#android:dimen/dialog_min_width_major</item>
<item name="android:windowMinWidthMinor">#android:dimen/dialog_min_width_minor</item>
</style>
There are no effects when pressing items in a dialog. What should I do to change background colors of dialog when pressed in xml file?
Additionally, is there any way to know the list of items that I can modify in xml file?(e.g. colorAccent, backgound, textColorPrimary ...)
You could try with MaterialDialogs library. It's easy to use and you could get the callbacks from buttons / radio / etc even if it's with a custom view.
(link : https://github.com/afollestad/material-dialogs/)
Try next code:
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorAccent">#color/accent</item>
<item name="android:dialogTheme">#style/DialogStyle</item>
<item name="android:alertDialogTheme">#style/DialogStyle</item>
</style>
<style name="DialogStyle" parent="Theme.AppCompat.Light.Dialog">
<item name="colorAccent">#color/accent</item>
<item name="android:windowTitleStyle">#style/DialogTitleStyle</item>
<item name="android:textColorAlertDialogListItem">#color/text_color</item>
<item name="android:textAppearanceButton">#style/DialogWindowTextButton</item>
<item name="android:windowBackground">#android:color/transparent</item>
</style>
<!--Colors and Styles-->
<color name="bar">#FF5722</color>
<color name="status_bar">#E64A19</color>
...

I've breaking my head over this quite a bit. What I need to do is, change the style of all AlertDialogs in my android application - dialog background needs to be white-ish, and text needs to be black-ish. I tried creating a lot of styles, themes, and applying from the code, manifest, etc, but no success, with regard to the text colors inside the AlertDialog. Right now, I have the simplest of codes, set like this:
Manifest:
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
styles.xml:
<style name="AppTheme" parent="AppBaseTheme">
<item name="android:alertDialogStyle">#style/DialogStyle</item>
</style>
<style name="DialogStyle" parent="#android:style/Theme.Dialog">
<!-- changing these background stuff works fine -->
<item name="android:bottomBright">#android:color/white</item>
<item name="android:bottomDark">#android:color/white</item>
<item name="android:bottomMedium">#drawable/dialog_footer_bg</item>
<item name="android:centerBright">#android:color/white</item>
<item name="android:centerDark">#drawable/dialog_body_bg</item>
<item name="android:centerMedium">#android:color/white</item>
<item name="android:fullBright">#color/orange</item>
<item name="android:fullDark">#color/orange</item>
<item name="android:topBright">#color/green</item>
<item name="android:topDark">#drawable/dialog_header_bg</item>
The items listed below don't work (please read the comments I've put above each element):
<!-- panelBackground is not getting set to null, there is something squarish around it -->
<item name="android:panelBackground">#null</item>
<!-- Setting this textColor doesn't seem to have any effect at all. Messages, title, button text color, whatever; nothing changes. -->
<item name="android:textColor">#000000</item>
<!-- Also tried with textAppearance, as follows. Didn't work -->
<item name="android:textAppearance">?android:attr/textColorPrimaryInverse</item>
<!-- Also tried changing textAppearancePrimary, to no avail -->
<item name="android:textColorPrimary">#000000</item>
<!-- Also need to change the dialog title text, tried it as follows, dint work: -->
<item name="android:windowTitleStyle">#style/DialogWindowTitle</item>
</style>
The DialogWindowTitle is defined as follows:
<style name="DialogWindowTitle">
<item name="android:textAppearance">?android:attr/textAppearanceMediumInverse</item>
</style>
So none of these is working. Can anyone tell me what I could be doing wrong, and how can I:
Change text color for messages (content text)
Change title text color
Remove the
panel background
Note: I need to support API 8 (2.2) upwards. Also, I've went through most of the related question here, and google groups, but can't figure out, though I have a feeling its right under my nose!
Edit: adding screenshot:
You need to define a Theme for your AlertDialog and reference it in your Activity's theme. The attribute is alertDialogTheme and not alertDialogStyle. Like this:
<style name="Theme.YourTheme" parent="#android:style/Theme.Holo">
...
<item name="android:alertDialogTheme">#style/YourAlertDialogTheme</item>
</style>
<style name="YourAlertDialogTheme">
<item name="android:windowBackground">#android:color/transparent</item>
<item name="android:windowContentOverlay">#null</item>
<item name="android:windowIsFloating">true</item>
<item name="android:windowAnimationStyle">#android:style/Animation.Dialog</item>
<item name="android:windowMinWidthMajor">#android:dimen/dialog_min_width_major</item>
<item name="android:windowMinWidthMinor">#android:dimen/dialog_min_width_minor</item>
<item name="android:windowTitleStyle">...</item>
<item name="android:textAppearanceMedium">...</item>
<item name="android:borderlessButtonStyle">...</item>
<item name="android:buttonBarStyle">...</item>
</style>
You'll be able to change color and text appearance for the title, the message and you'll have some control on the background of each area. I wrote a blog post detailing the steps to style an AlertDialog.
Remove the panel background
<item name="android:windowBackground">#color/transparent_color</item>
<color name="transparent_color">#00000000</color>
This is Mystyle:
<style name="ThemeDialogCustom">
<item name="android:windowFrame">#null</item>
<item name="android:windowIsFloating">true</item>
<item name="android:windowContentOverlay">#null</item>
<item name="android:windowAnimationStyle">#android:style/Animation.Dialog</item>
<item name="android:windowBackground">#color/transparent_color</item>
<item name="android:windowSoftInputMode">stateUnspecified|adjustPan</item>
<item name="android:colorBackgroundCacheHint">#null</item>
</style>
Which i have added to the constructor.
Add textColor :
<item name="android:textColor">#ff0000</item>
Here's my Code to theme the alert dialog box:
<style name="alertDialog" parent="Theme.AppCompat.Dialog.Alert">
<item name="android:background">#color/light_button_text_color</item>
<item name="android:textColor">#android:color/black</item>
<item name="android:textColorPrimary">#android:color/black</item>
<item name="android:textColorSecondary">#android:color/black</item>
<item name="android:titleTextColor" tools:targetApi="m">#android:color/black</item>
</style>
Place this code in styles.xml.
In your java apply this theme as:
AlertDialog.Builder builder = new AlertDialog.Builder(this, R.style.alertDialog);
Output of the code
You have to add the style to the constructor of the dialog
builder = new AlertDialog.Builder(this, R.style.DialogStyle);
I changed color programmatically in this way :
var builder = new AlertDialog.Builder (this);
...
...
...
var dialog = builder.Show ();
int textColorId = Resources.GetIdentifier ("alertTitle", "id", "android");
TextView textColor = dialog.FindViewById<TextView> (textColorId);
textColor?.SetTextColor (Color.DarkRed);
as alertTitle, you can change other data by this way (next example is for titleDivider):
int titleDividerId = Resources.GetIdentifier ("titleDivider", "id", "android");
View titleDivider = dialog.FindViewById (titleDividerId);
titleDivider?.SetBackgroundColor (Color.Red);
this is in C#, but in java it is the same.
It depends how much you want to customize the alert dialog. I have different steps in order to customize the alert dialog. Please visit: https://stackoverflow.com/a/33439849/5475941
Building on #general03's answer, you can use Android's built-in style to customize the dialog quickly. You can find the dialog themes under android.R.style.Theme_DeviceDefault_Dialogxxx.
For example:
builder = new AlertDialog.Builder(this, android.R.style.Theme_DeviceDefault_Dialog_MinWidth);
builder = new AlertDialog.Builder(this, android.R.style.Theme_DeviceDefault_Dialog_NoActionBar);
builder = new AlertDialog.Builder(this, android.R.style.Theme_DeviceDefault_DialogWhenLarge);
Use this in your Style in your values-v21/style.xml
<style name="AlertDialogCustom" parent="#android:style/Theme.Material.Dialog.NoActionBar">
<item name="android:windowBackground">#android:color/white</item>
<item name="android:windowActionBar">false</item>
<item name="android:colorAccent">#color/cbt_ui_primary_dark</item>
<item name="android:windowTitleStyle">#style/DialogWindowTitle.Sphinx</item>
<item name="android:textColorPrimary">#color/cbt_hints_color</item>
<item name="android:backgroundDimEnabled">true</item>
<item name="android:windowMinWidthMajor">#android:dimen/dialog_min_width_major</item>
<item name="android:windowMinWidthMinor">#android:dimen/dialog_min_width_minor</item>
</style>
And for pre lollipop devices put it in values/style.xml
<style name="AlertDialogCustom" parent="#android:style/Theme.Material.Dialog.NoActionBar">
<item name="android:windowBackground">#android:color/white</item>
<item name="android:windowActionBar">false</item>
<item name="android:colorAccent">#color/cbt_ui_primary_dark</item>
<item name="android:windowTitleStyle">#style/DialogWindowTitle.Sphinx</item>
<item name="android:textColorPrimary">#color/cbt_hints_color</item>
<item name="android:backgroundDimEnabled">true</item>
<item name="android:windowMinWidthMajor">#android:dimen/dialog_min_width_major</item>
<item name="android:windowMinWidthMinor">#android:dimen/dialog_min_width_minor</item>
</style>
<style name="DialogWindowTitle.Sphinx" parent="#style/DialogWindowTitle_Holo">
<item name="android:textAppearance">#style/TextAppearance.Sphinx.DialogWindowTitle</item>
</style>
<style name="TextAppearance.Sphinx.DialogWindowTitle" parent="#android:style/TextAppearance.Holo.DialogWindowTitle">
<item name="android:textColor">#color/dark</item>
<!--<item name="android:fontFamily">sans-serif-condensed</item>-->
<item name="android:textStyle">bold</item>
</style>
