问题 My Android Application has a main Project Module that has the following declaration in the styles file. This Theme is used in the Manifest file on the "application" tag so all components within the "application" element have the same theme applied. <!-- Base application theme. --> <style name="AppTheme" parent="Theme.AppCompat.NoActionBar"> <item name="android:colorPrimary" tools:ignore="NewApi"> @color/light_black </item> <item name="colorPrimary">@color/light_black</item> <item name=

问题 I am trying to define an attribute for any view using the Data Binding Library, as explained in this Android Developers post. To do so, the post says one first needs a layout with an enclosing <layout> tag: <?xml version="1.0" encoding="utf-8"?> <layout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto"> <LinearLayout android:orientation="vertical" android:layout_width="match_parent" android:layout_height="wrap_content"> <TextView

Android “?colorPrimary” vs “?attr/colorPrimary”?

由 大憨熊 提交于 2019-12-07 09:07:31
问题 I can't find any information about the differences between: android:textColor="?attr/colorPrimary" vs android:textColor="?colorPrimary" I have read that "?attr" means attribute value specified in the current theme, but without "attr" it gives the same result (=color defined in my theme). It behaves similar with other attributes? For example: Does android:background="?attr/selectableItemBackground" equals android:background="?selectableItemBackground" ? Here it's told that it differs. Thanks

How to reference style attributes from a drawable?

由 随声附和 提交于 2019-11-26 11:07:32
I want to have 2 selectable themes for my application. In order to do that, I defined some attributes, like this: <attr format="color" name="item_background" /> Then, I created both themes, like this: <style name="ThemeA"> <item name="item_background">#123456</item> </style> <style name="ThemeB"> <item name="item_background">#ABCDEF</item> </style> This method works great, allowing me to create and modify several themes easily. The problem is that it seems that it can be used only in Views, and not in Drawables . For example, referencing a value from a View inside a layout works: <TextView
