I have a custom DialogPreference Dialog that has its layout set out in a relativelayout that contains the following:
Checkbox
Textview
Text Field
This is fine in Android 4.0+, because the theme we are using is Theme.Light so the background color of the dialog is white and the default text is black for the Checkbox label and textview. However, in 2.3.3, the background color is dark grey so it becomes hard to see the text... the theme is still Theme.Light however.
I thought that making a custom dialog would be necessary for this because the checkbox enable/disables the text field. At the moment, I'm making the background color of the relativelayout for this Dialog white... but I don't really like this solution as there maybe cases where some other phones on 2.3.3 may not have white as the default dialog background...
Is there a cleaner way to fix this problem?
I notice this person has the same problem: Custom Support Dialog Fragment text is the wrong color
Another with the problem :Android: Issue with showing dialog from Theme.Light activity
EDIT: Attached screenshot. This is what it looks like on LG Optimus 2X running 2.3.3. On my co-worker's samsung galaxy which runs 2.3.3 also, the background is even darker so you can hardly see the text.
You could make custom dialog theme in style files , such as:
less than API 11:
<style name="MyDialogTheme" parent="android:Theme.Light" >
API 11 and forward:
<style name="MyDialogTheme" parent="android:Theme.Holo.Dialog" >
then use "MyDialogTheme" in your Fragment dialog:
... ...
ContextThemeWrapper context = new ContextThemeWrapper(getActivity(), R.style.MyDialogTheme);
AlertDialog.Builder builder = new AlertDialog.Builder(context);
... ...
hope this help.

This question should be simple, but i didn't find an answer. I have an app with selectable accent, and i'm trying to add an option to use the android system accent (apps like Lawnchair have such an option). In the style for the system accent, i tried to get this accent in every way possible:
?android:colorAccent
?android:attr/colorAccent
?attr/colorAccent
And this is the style:
<style name="AppTheme.systemAccent" parent="AppTheme">
<item name="colorAccent">???</item>
</style>
Nothing seems to work and the app crashes, but i'm certain that this is possible. The accent selection, when i use normal colors, works fine. Where am i wrong?
EDIT: Just to be clear, i'm trying to get the system accent color, i.e. the system wide color used in settings, notification panel and so on. This color is now selectable in Android 10 and was selectable before in rom like the Oxygen OS. Let's say i select a red accent in settings->customization on my Android 10 device. I want to get this red accent in my app
You can get it programmatically:
TypedValue typedValue = new TypedValue();
ContextThemeWrapper contextThemeWrapper = new ContextThemeWrapper(this,
android.R.style.Theme_DeviceDefault);
contextThemeWrapper.getTheme().resolveAttribute(android.R.attr.colorAccent,
typedValue, true);
int color = typedValue.data;
Just to be clear I am referring to the Android Q System color accent:
Okay. I did some intensive research and trial and error. After that I found out, that I could access a private property #*android:color/accent_device_default_light. BUT this is just possible if you change your parent class for the activity from AppCompatActivity to Activity because the AppCompat can't set up the toolbar with this private property. Further it's not recommended to use private properties because they are likely to get deleted or changed in the future.
#color/colorAccent
use this ,it's default color in android
or you can customize your color in the color.xml
In my activity theme in the themes.xml I have set a background color in order to move away from the default (transparent/white?) background color to my own.
<item name="android:background">#color/red</item>
Unfortunately, when the I am showing my loading dialog the color shines halfway through that dialog now. Was this to be expected?
I have tried to use different themes, also defined by own dialog theme subclassing from Holo Light setting the background color explicitly to white, but the problem persists, only the currently still white areas are changed in this case.
What can I do? The only alternative is currently to use the Tradiotional Dialog Theme.
Try to set android:windowBackground instead. android:background attribute is applied to all nested views. Here is the discussion: What's the difference between windowBackground and background for activities style?
It looks like there's some padding or margins to the left and right of the title. If you're using the built-in ProgressDialog I'd suggest creating your own Dialog instead, that way you can change anything you want about it. Just create your own xml layout and create the dialog like this:
protected static Dialog getProgressDialog(Activity activity) {
Dialog dialog = new Dialog(activity);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
LayoutInflater inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View progressDialogView = inflater.inflate(R.layout.custom_progress_dialog, null);
dialog.setContentView(progressDialogView);
dialog.setCancelable(false);
return dialog;
}
I am trying to add a custom style to an Android NumberPicker. What I am trying to do is have the text displayed by the picker as white since by default (or according to the default theme on the device) I have it in black. The problem is that my app background is a dark color so I want the text to be white or something clear.
so I have something like this in my style.xml file :
<style name="myPicker">
<item name="android:textColor">#FFFFFF</item>
</style>
the textcolor attribute doesn't even exist on the NumberPicker widget but I just tried to add it so that my text color changes. It does not work of course. The only thing that can be customized on this widget seems to be the background
Now the question : how can we change the text color of the picker ?
if somebody has the same issue or has solved it then please let us know.
I have found an "ugly" way to do it. Just get a reference to the child views of the number picker widget. There are three (3) child views : the upper arrow, the textview (containing the text or value to be displayed) and the lower arrow.
Let's say we have a Number picker called np
np.setValue(10);
np.setMinValue(5);
np.setMaxValue(50);
// retrieve the textview reference
TextView npTextView = (TextView) np.giftAmount.getChildAt(1); // since indexing begins at 0
npTextView.setTextColor(getResources().getColor(
R.color.my_custom_color)
I know that's bad but it works ...
The horizontal progressbar in ActionbarSherlock is too thin, and is very hard to see. How can I style it to be a few pixels thicker?
I've tried applying a custom style in styles.xml by inhering the style from Widget.Sherlock.Light.ProgressBar.Horizontal, but it's really confusing and I don't know which properties to set.
Instead of attempting to make the ProgressBar thicker, try using a color that contrasts from the ActionBar color to make it stand out, and be noticible.
That's what I did with my app. I have a grey ActionBar, with a bright red ProgressBar.
Hope this helps!
I am trying To show a dialog from a PreferenceActivity, which is set to Theme.Light. The dialog shows with dark text on a dark background:
I assume it uses dark text because it is inheriting the text color from the parent activity, or something similar. I would like the dialog to either use white text on the dark background, or use a white background with dark text, as the PreferenceActivity does when set to Theme.Light.
This seems to be a known problem, the workarounds I have found involve creating and using a custom style that extends Theme.Dialog and using it to instantiate the dialog. Something like:
<style name="CustomDialog" parent="#android:style/Theme.Dialog">
<item name="android:textColor">?android:attr/textColorPrimaryInverseDisableOnly</item>
</style>
Dialog dialog = new Dialog(context, R.style.CustomDialog);
I tried this, but it made no difference. I also tried a number of different values for textColor, none of which modified the Dialog's text color. As a sanity check, I added:
<item name="android:background">#FFFF0000</item>
to the style, which resulted in a dialog with a red background (so I am sure that I am instantiating the dialog properly).
The closest I have come to a solution is just setting the dialog's background color to white, which gives the below dialog. But this is not a good solution, because some version or some device might not use the same behavior I am seeing when inverting text color:
So, is there a good way to set text color on a dialog displayed from a Theme.Light activity?
I assume that you use AlertDialog.Builder and set the list using one of the setSingleChoiceItems methods which doesn't use your own ListAdapter. Instead it creates its own instead with the wrong style. To fix this, you should call setSingleChoiceItems(ListAdapter adapter, int checkedItem, DialogInterface.OnClickListener listener) and provide such an adapter which would use a layout with the needed style.
Now, why this happens. The actual adapter creation happens in the file com.android.internal.app.AlertController, where the following line selects the layout for single choice lists:
int layout = mIsSingleChoice
? R.layout.select_dialog_singlechoice : R.layout.select_dialog_item;
Here is the aforementioned layout:
<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/text1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="?android:attr/listPreferredItemHeight"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textColor="#android:color/primary_text_light_disable_only"
android:gravity="center_vertical"
android:paddingLeft="12dip"
android:paddingRight="7dip"
android:checkMark="#android:drawable/btn_radio"
android:ellipsize="marquee"
/>
As you can see, the line which sets the text color contains not a reference to a theme, but a hardwired color. That's why when this thing gets inflated during the list creation, it will always use the same color, regardless of what style you want it to use. So the right action to overcome this problem is to use your own layout and your own ListAdapter.
