android-styles

I have created a custom widget, and I'm declaring it in layout.xml. I have also added some custom attributes in attr.xml. However, when trying to declare these attributes in a style in styles.xml, it's giving me No resource found that matches the given name: attr 'custom:attribute'. I have put the xmlns:custom="http://schemas.android.com/apk/res/com.my.package" in all of the tags in styles.xml, including <?xml> , <resources> , and <style> , but it still gives me the same error, that it can't find my custom XML namespace. I can, however, use my namespace to manually assign attributes to the

Since today, Android Studio can't find the AppCompat themes in styles.xml, but for example AppCompatActivity in code does get recognized. My Android Studio version is 2.2.2, Build #AI-145.3360264 I already tried upgrading to the latest build tools, compile sdk (25) version etc. but it didn't fix the problem.

I've added a RatingBar in a layout: <RatingBar android:id="@+id/ratingbar" android:layout_width="wrap_content" android:layout_height="wrap_content" android:numStars="5" android:stepSize="1.0" /> But the default style for the rating bar is too large. I've try to change it by adding the android style : style="?android:attr/ratingBarStyleSmall" But the result is too small and it's impossible to set a rate with this property. How could I do? The default RatingBar widget is sorta' lame. The source makes reference to style " ?android:attr/ratingBarStyleIndicator " in addition to the " ?android:attr

I'm trying to add a CalendarView in my application, which uses the Theme.Light theme. The problem is, the days numbers of this calendar are rendered in white, so while using a light theme, you can't see them. Right now, I have the following code in my XML layout file : <CalendarView android:id="@+id/calendar1" android:layout_width="500dp" android:layout_height="300dp"/> I tried to force the calendar theme like this : <CalendarView android:id="@+id/calendar1" android:layout_width="500dp" android:layout_height="300dp" android:theme="@android:style/Theme.Light" /> But it doesn't change anything.

How can I change the focus color (orange) on an EditText box? The focus color is a small rim around the entire control and is bright orange when the control has focus. How can I change the color of that focus to a different color? Can anyone help me in sorting out this issue?

If you look in your SDK folder, under your platform, then res/drawable, you should find the NinePatch image for the EditText focus state. If that's all you want to

Can anyone explain the question mark means in Android XML attributes? <TextView style="?android:attr/windowTitleStyle" More attributes /> jball The question mark means it's a reference to a resource value in the currently applied theme. See the linuxtopia Android Dev Guide or the android.com Dev Guide for more about it. \? escapes the question mark.

It makes the most sense when considering multiple themes
