I use Acr.UserDialogs to create cross-platform dialogs from a Xamarin Shared/PCL project. Acr.UserDialogs contains a method to create a prompt which (in Android) is an AlertDialog whose View is set to an EditText. Unfortunately the View/EditText has no margin/padding which results in it reaching until the outer left and right limits of the dialog - which looks pretty ugly. Due to it being a library I have no ability to change how exactly the EditText or the AlertDialog are created (rather than editing the libraries code on GitHub myself but that's a way I try to avoid for now if possible). What the library supports is the possibility to pass an AndroidStyleId into the call that it uses instead of the default Android AlertDialog style (new AlertDialog.Builder(activity, passedAndroidStyleId)).
Now, my idea is to create a style that defines a custom margin/padding/inset to the View of the AlertDialog kind of as follows and pass it in.
<style name="CustomPromptDialog" parent="ThemeOverlay.AppCompat.Dialog.Alert">
<item name="viewInset">10dp</item>
</style>
Problem is I can't find any resources listing which "properties" can be set in a style or how they are named, so my only idea was to ask here:
Is there any way to achieve what I'm trying to do? And if yes, how?
You can set the style like this to change the form of the Alertdialog. This the method for globel setting.
<style name="MainTheme" parent="MainTheme.Base">
<item name="android:datePickerDialogTheme">#style/Theme.picker</item>
<item name="alertDialogTheme">#style/Theme.alert</item>
</style>
<style name="Theme.alert" parent="ThemeOverlay.AppCompat.Dialog.Alert">
<item name="colorAccent">#FFC107</item>
<!-- Used for the title and text -->
<item name="android:textColorPrimary">#FFC107</item>
<!-- Used for the background -->
<item name="android:background">#4CAF50</item>
<item name="viewInset">10dp</item>
I have found some similar questions on this topic but it works for support version and not on androidx. I wasn't able to make this change on androidx. But on the previous support version there are solutions for it already. Can anyone give me some directions on how I can change the title and editetext field text color in EditTextPreference? Currently the color is white and with the background being white too, the texts are not visible.
And here are the solutions I found on stackoverflow already but I wasn't able to use.I would like to change the white text color to black. Thank you.
from adneal's solution
from Murphybro2's solution
In the thread of Murphybro2's solution we got also the solution for androidx
https://stackoverflow.com/a/58836953
You can change the AlertDialogStyle used by your app by providing a custom Theme style
<style name="AppTheme.Settings">
<!-- This will change the opening dialogs for EditTextPreference -->
<item name="alertDialogStyle">#style/Theme.example.AlertTheme</item>
</style>
<style name="Theme.example.AlertTheme" parent="">
<item name="android:textViewStyle">#style/Theme.AlertTextStyle</item>
<item name="android:textColor">#color/pink</item>
<item name="android:editTextBackground">#color/pink</item>
<item name="android:windowMinWidthMajor">#dimen/abc_dialog_min_width_major</item>
<item name="android:windowMinWidthMinor">#dimen/abc_dialog_min_width_minor</item>
<item name="android:windowIsFloating">true</item>
</style>
<style name="Theme.AlertTextStyle" parent="Theme.example">
<item name="android:textColorPrimary">#color/gray</item>
</style>
The most important one for me was "windowIsFloating">true because else the window is stuck to the top of your screen
For me somehow only adding the extra textViewStyle helped to change the top text inside the dialog, but I think its because of my example theme.
I was able to change the color of the title of the dialog box created by the androidx.preference.EditTextPreference in the way presented in that answer. But I could not change the color of the text in the EditText widget placed in that dialog in that way and I needed to use the following method.
AndroidX version of EditTextPreference allows you to set a listener on the event of binding the EditText. You can use it for example in onCreatePreferences of the androidx.preference.PreferenceFragmentCompat class to change the attributes of the EditText widget.
override fun onCreatePreferences() {
super.onCreatePreferences()
findPreference<EditTextPreference>("my_preference_key")?.let {
it.setOnBindEditTextListener { editText ->
editText.setTextColor(Color.BLACK)
}
}
}
}
I'm trying to style all my dialog fragments to look the same in my app. The dialogs coming from my settings fragment are styled exactly the way I want it. For my custom dialog fragments, the style is similar but not exactly the same. For some reason the spinner, timepicker, datepicker, radiobuttons, and edittext widgets inside my custom dialog fragments don't pick up the same style. In fact, the widgets blend in with the white background and you can't see that they are there. What am I doing wrong?
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar"/>
<style name="Theme.Base" parent="AppTheme">
<item name="colorPrimary">#color/PrimaryBackgroundColor</item>
<item name="colorPrimaryDark">#color/SecondaryBackgroundColor</item>
<item name="colorAccent">#color/ColorBackgroundAccent</item>
<item name="android:textColorPrimary">#color/PrimaryTextColor</item>
<item name="android:alertDialogTheme">#style/AppTheme.DialogStyle</item>
</style>
<style name="AppTheme.DialogStyle" parent="Theme.AppCompat.Light.Dialog.Alert">
<item name="android:textColorPrimary">#color/PrimaryBackgroundColor</item>
<item name="colorAccent">#color/ColorBackgroundAccent</item>
</style>
I'm applying the theme to my custom dialog fragment like this:
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity(), R.style.AppTheme_DialogStyle);
My settings dialog looks like this (Exactly how I want it):
Settings Dialog Fragment
My custom dialog fragment looks like this:
Custom Dialog Fragment
As you can see, the radio button selected color red and you can't see the unselected radio button.
Finally got an answer!!!
It's an issue or bug with AppCompat 22+.
Check out link here
Apparently this was a bug with fragments and widgets weren't getting the material themed in a fragment. It seems they fixed this issue, but the issue still holds in a dialog fragment based on what I'm going through.
The problem comes when you use the inflater instance passed to Fragment#onCreateView(). The workaround for now is to instead used the LayoutInflater from getActivity().getLayoutInflater() according to google.
So I changed my code to:
View view = getActivity().getLayoutInflater().inflate(R.layout.dialog, null);
from:
View view = LayoutInflater.from(getActivity().getApplicationContext()).inflate(R.layout.dialoge, null);
All my widgets are now themed. Thanks everyone. Hopes this helps someone else.
I believe you need to set the theme on the actual Dialog and not the Fragment
Use this constructor to create your AlertDialog:
AlertDialog.Builder(Context context, int theme)
ie
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity(), theme)
I think you need to add one more item in style of your dialog. android:textColorSecondary will show color of un selected checkbox.
in your style add it.
</style>
<style name="AppTheme.DialogStyle" parent="Theme.AppCompat.Light.Dialog.Alert">
<item name="android:textColorPrimary">#color/PrimaryBackgroundColor</item>
<item name="colorAccent">#color/ColorBackgroundAccent</item>
<item name="android:textColorSecondary">#000000</item>
</style>
It will make un Checked checkbox or toggle button edge color black. you need to change #000000 to color your want to show.
See if this helps -
Android appcompat-v7:21.0.0 change material checkbox colors
In short, try setting android:textColorSecondary.
Is there a way to format all TextViews, Buttons or whatever with a theme ?
Like in CSS when i want to format all a-tags
a{
/some css here/
}
I want to do that in android via xml when I'm applying a theme to my application.
Any ideas ?Thanks

Update 1.0:
I want to create a theme that formats the text in all TextViews green and in all EditTexts red. So that i just apply the theme and I never have to worry about the style attribute!
Update 1.1:
So I found some that piece of code and I think that's a good beginning
<item name="android:textViewStyle">#style/MyTextView</item>
<item name="android:buttonStyle">#style/MyButton</item>
I think thats the answer to my question. But I have another one. I want to write my own ActionBar and wanted to know how I can apply a default style or default attributes (again without adding the style attribute in the layout xml :P )
I have a class
public class ActionBar extends LinearLayout{ }
and I'm gonna use it like that in my application
<at.bartinger.uil.ActionBar>....</at.bartinger.uil.ActionBar>
The ActionBar should have some default attributes (like height and width) and then adding some custom style attributes which could change from app to app (like background)
yes you can you can apply a theme to the whole application and then all your textviews will have that style.
Inside the styles.xml file you have to define your CustomTheme
for example:
<style name="CustomTheme" parent="android:Theme.Light">
<item name="android:windowBackground">#color/custom_theme_color</item>
<item name="android:colorBackground">#color/custom_theme_color</item>
</style>
you add something like text
"android:textStyle="myStyle" and specify the details in Mystyle
You can apply a style read more here.
for the action abr you should look here http://developer.android.com/guide/topics/ui/actionbar.html
especially at the bottom it explains very well how to style the bar
I am trying to use a custom title to include an image button to the title bar.
I got a lot of help form this post: android: adding button to the title of the app?, but could not get it work for my ListActivity.
In a nutshell, following is what I have:
I hide the titlebar in the AndroidManifest.xml
The specify a relative layout for the custom title (workorder_list_titlebar.xml)
My Activity Class looks like the following:
public class WorkOrderListActivity extends ListActivity {
String[] orders={"WO-12022009", "WO-12302009","WO-02122010", "02152010"};
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
this.getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.workorder_list_titlebar);
setContentView(R.layout.workorder_list);
setListAdapter(new ArrayAdapter(this,R.layout.workorder_list, R.id.label,orders));
}
}
When I ran the app, I got AndroidRuntimeException: You cannot combine custom titles with other title features.
Base on the stack trace, the exception was thrown by com.android.internal.policy.impl.PhoneWindow.requestFeature(PhoneWindow.java:183), that was triggered by setlistAdapter call.
Does anyone have the same problem with ListActivity?
Also once I manage to get this work, how do I attach listeners to the image button for it to do something?
Thanks in advance.
I had the same issue and I fix it deleting
<item name="android:windowNoTitle">true</item>
from my theme.xml
Make you create custom style in “values” folder. Make sure you code as below.
<style name="CustomTheme" parent="android:Theme">
Don't modify parent parameter.
This did work for me.
Instead of modifying your theme.xml you may also:
create a new XML style file my_theme.xml in values folder like this:
<style name="MyWindowTitleBackground">
<item name="android:background">#444444</item>
</style>
<style name="MyTheme" parent="android:Theme">
<item name="android:windowTitleBackgroundStyle">#style/MyWindowTitleBackground</item>
</style>
You may define other settings as you like in this theme.
Then just use this theme in your manifest within the activity's attributes
android:theme="#style/MyTheme"
Finally set your custom title as always in your activity.java:
final Window window = getWindow();
boolean useTitleFeature = false;
// If the window has a container, then we are not free
// to request window features.
if (window.getContainer() == null) {
useTitleFeature = window
.requestFeature(Window.FEATURE_CUSTOM_TITLE);
}
setContentView(R.layout.screen_main);
if (useTitleFeature) {
window.setFeatureInt(Window.FEATURE_CUSTOM_TITLE,
R.layout.custom_title);
// Set up the custom title
main_title = (TextView) findViewById(R.id.title_left_text);
main_title.setText(R.string.app_name);
main_title = (TextView) findViewById(R.id.title_right_text);
main_title.setText(R.string.Main_titleInfo);
}
Don't forget to define the custom_title.xml file in your layout folder. For example...
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center_vertical" >
<TextView
android:id="#+id/title_left_text"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_alignParentLeft="true"
android:ellipsize="end"
android:singleLine="true" />
<TextView
android:id="#+id/title_right_text"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_centerInParent="true"
android:ellipsize="end"
android:singleLine="true"
android:textColor="#fff" />
</RelativeLayout>
I think notenking is right, that this is a problem in activities within tabs. Since some of my activities can either be stand-alone or within a tab, I've found the following helps:
final Window window = getWindow();
boolean useTitleFeature = false;
// If the window has a container, then we are not free
// to request window features.
if(window.getContainer() == null) {
useTitleFeature = window.requestFeature(Window.FEATURE_CUSTOM_TITLE);
}
setContentView(layoutId);
if (useTitleFeature) {
window.setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.window_title);
}
May be you find this problem when use it in tab,for there already have a title and you can not add a custom title again.
you should add this custom title in the activity which you get the Tab
I did exactly as Sunny Dasari did but with one small change I put the # before and android in the parent attribute.
So my code looked like this.
<style name="CustomTheme" parent="#android:Theme">
To avoid crashing, you can simply add
android:theme="#style/android:Theme"
to the <Activity> tag in your AndroidManifest.xml:
<activity
android:name="test.TestActivity"
android:label="#string/app_name"
android:theme="#style/android:Theme">
This is because the styles defined in your default theme conflict with FEATURE_CUSTOM_TITLE (such as the attribute android:windowNoTitle). By using another theme, you can avoid such problems.
However, you might further need to define your own theme to change other attributes, such as android:windowTitleSize, background color, text color and font, etc. In this case, you can derive your theme from an existing theme (e.g., Theme.Light) and modify its attributes:
<resources>
<style name="CustomWindowTitleBackground">
<item name="android:background">#323331</item>
</style>
<style name="CustomTheme" parent="#style/android:Theme.Light">
<item name="android:windowNoTitle">false</item>
<item name="android:windowTitleSize">60dip</item>
<item name="android:windowTitleBackgroundStyle">#style/CustomWindowTitleBackground</item>
</style>
</resources>
Try swapping following lines:
setContentView(R.layout.workorder_list);
this.getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.workorder_list_titlebar);
I have run into this issue as well and it looks like it is an issue with what theme is applied to an activity in the AndroidManifest.xml file. If I use a theme like:
android:theme="#android:style/Theme.Holo
Then it will throw the error
android.util.AndroidRuntimeException: You cannot combine custom titles with other title features
However if I use a different theme like:
android:theme="#android:style/Theme.Black"
then it will not throw the error and subsequently will not crash. However I am trying to use a theme like Theme.Holo. I'm not sure if there is a way around this.
Since, I was trying to compile my program in android 4.0, I was facing the same problem. None of these solutions helped.So, I copied my style contents from values > styles.xml and pasted it in values-v11 styles.xml file and values-v14 styles.xml file. Bingo, the trick worked.
As a beginner most of the answers didn't help me for my case. So here is my answer.
Go to res/values folder in your android project and check for strings.xml (this file may vary in your case, something like themes.xml)
Inside the file under resource tag check whether you have style tags. If you don't find it, add the code below as mentioned below as a child to resources tag
something like below
<resources>
<style name="SomeNameHere">
<item name="android:windowNoTitle">true</item>
</style>
</resources>
if you already have style tag, just add the code below to your style tag
<item name="android:windowNoTitle">true</item>
