I have an Android project using another one as library. So far I've been working on Eclipse with Maven, now I want to migrate to Android Studio and Gradle.
The problem is that I use to do the following in Eclipse:
Library project:
<style name="some_theme">
<item name="android:textColor">#00FF00</item>
</style>
And then in my main project:
<style name="some_theme">
<item name="android:typeface">monospace</item>
</style>
So, if the theme name is the same in Eclipse I get whats been defined in both themes, but in Android studio I only get what's on the main project
Has someone encounter this type of issue before? Does someone know a way to solve it? (Other than just copy all what's on the library project...)
Regards
Jose
That shouldn't work. When you define two styles with the same name in two different places, you should run into a naming conflict. There is no documented style resource merging feature. The fact that it works in Eclipse with ADT is probably accidental.
The correct way to do this is to define one style in your library, and inherit from that style in your application.
For example, in your library project:
<style name="SomeThemeBase">
<item name="android:textColor">#00FF00</item>
</style>
Then in your application project:
<style name="AppTheme" parent="SomeThemeBase">
<item name="android:typeface">monospace</item>
</style>
This way you do not create a naming conflict, but your app's theme still inherits the properties you defined on the base theme.

I created a project in Eclipse, worked a lot of in it and changed my IDE to Android-Studio. Now I need to change some things in style.xml and found out, that i did not was generated.
It possible to let it generate now?
PS: I added the library com.android.support:support-v13:22.1.1 to my project.
It could be under themes.xml
Here's a simple styles.xml template with my Activity extending AppCompatActivity
<resources>
<style name="AppTheme" parent="Theme.AppCompat">
</style>
</resources>
It's under res->values->styles.xml
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorAccent">#color/colorAccent</item>
<item name="android:textColorPrimary">#color/colorTextPrimary</item>
<item name="android:textColorSecondary">#color/colorTextSecondary</item>
</style>
This is the styles.xml file. The following code results in this error - i have put all the necessary libraries and jar files and i have also tried changing the syntax little bit and many stuff but I am not able to solve the problem. It is very important. Please help me. Thank you.
I have tried the following :
You need to reference this AppCompat library in your Android project.
Import the library into Eclipse.
Right click on your Android project.
Select properties.
Click 'add...' at the bottom to add a library.
Select the support library
Clean and rebuild your project.
It still doesn't work.
Edit now :
I have installed android sdk 5.0 (API 21) but it still doesn't work. The line with the error is
There were 3 other errors before installing android sdk 5.0 (API 21) in this file (styles.xml) but now they are gone. Please help me to remove the remaining error.
If you are using material in the manifest, you will get this error if your min version isn't API 21
Is there any way to create an app with Material design in Eclipse? Hamburger to arrow animation, full screen height navigation drawer...
Yes you can create an app with material design using eclipse.
Please follow each steps below carefully without any error.
Steps:
Create a new Android Project with Target SDK version 21. If your project already exists then just change the Target SDK version.
Add Appcompat v7 lib to your workspace and add this lib to build path of your project. You can find this lib at sdk\extras\android\support\v7.
Set Project build target to version 21.
There should be only 2 values folder in res folder.
values
values-v21
values/styles.xml should be as below.
<style name="AppBaseTheme" parent="Theme.AppCompat.Light.DarkActionBar">
....
// Your style here
</style>
values-v21/style.xml should be as below.
<style name="AppBaseTheme" parent="#android:style/Theme.Material.Light.DarkActionBar">
....
// Your style here
</style>
You can find different style attributes here https://developer.android.com/training/material/theme.html
After following above steps, your app will be ready with material design theme.
Now your second question regarding navigation drawer you can use following link for simple and step by step implementation.
Part 1 http://www.android4devs.com/2014/12/how-to-make-material-design-navigation-drawer.html4
Part 2 http://www.android4devs.com/2015/01/recycler-view-handling-onitemtouch-for.html
This implementation uses recycler view. For that you need to add recycler view lib (location - sdk\extras\android\support\v7) to your project and add it to build path.
You can develop apps with Material Design in Eclipse by using the libraries provided by google. You need to follow the below steps to do that.
Properties> Android> Add...>appcompat_v7
Add...> Android Design Support Library(You can import it from android-sdk\extras\android\support\)
Add...> RecycleViewLibrary & CardViewLibrary libraries for RecycleView and cardView, better material look and feel. (You can import it from android-sdk\extras\android\support\v7\)
Add/Edit values\styles.xml
<style name="MyMaterialTheme.Base" parent="Base.Theme.AppCompat.Light.DarkActionBar">
<item name="windowNoTitle">true</item>
<item name="windowActionBar">false</item>
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
</style>
Change theme in AndroidManifest.xml file. android:theme="#style/MyMaterialTheme"
extend your Activity by AppCompatActivity.
Hope you can develop Material Designed apps in Eclipse throgh these steps.
Important: Support for the Android Developer Tools (ADT) in Eclipse is ending. You should migrate your app development projects to Android Studio as soon as possible.
I am trying to customize the material design theme as suggested in this link :
android dev
but when I add the following code to my v21/styles file Intellij says that it cannot resolve these symbols.
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light">
<!-- customize the color palette -->
<item name="colorPrimary">#color/material_blue_500</item>
<item name="colorPrimaryDark">#color/material_blue_700</item>
<item name="colorAccent">#color/material_green_A200</item>
</style>
</resources>
I looked around to see if there are any particular settings that need to be done on the color side but nothing came up. I am using API 21 with support lib v7 on gradle.
#color/material_blue_500 and others are not the resources in android library.
You must define the color resources in res/values/colors.xml by yourself.
such as <color name="material_blue_500">#5677fc</color>.
And then you can use it as <item name="colorPrimary">#color/material_blue_500</item>.
Android docs are very vague on this, leading to confusion. To get the predefined colors copy color_material.xml to your local res/values dir. That file is a preserved version as it was during Android-L. The offical version which sits in your local directory:
...sdk/platforms/android-21/data/res/values/colors_material.xml
has been trimmed down to remove those color definitions.
I am trying to run an simple android project from a tutorial, However I am receiving the popular "R cannot be resolved to a variable" error. I have checked my gen folder and the R.id file is not there. This is the list of things I have tried so far:
have done a clean build several billion times.
fixed the project properties
There are no errors in my .xml files and they do not contain uppercase letters etc.
The package name in the source and manifest are exactly the same.
Have installed the latest SDK updates + restarted eclipse.
have deleted the gen file and done another clean build.
There is only an error in the source files, according to eclipse.
Here is a themes.xml file that may be causing a problem:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<!-- the theme applied to the application or activity -->
<style name="CustomActionBarTheme"
parent="#android:style/Theme.Holo">
<item name="android:actionBarStyle">#style/MyActionBar</item>
<item name="android:actionBarTabTextStyle">#style/MyActionBarTabText</item>
<item name="android:actionMenuTextColor">#+color/actionbar_text</item>
</style>
<!-- ActionBar styles -->
<style name="MyActionBar"
parent="#android:style/Widget.Holo.ActionBar">
<item name="android:titleTextStyle">#style/MyActionBarTitleText</item>
</style>
<!-- ActionBar title text -->
<style name="MyActionBarTitleText"
parent="#android:style/TextAppearance.Holo.Widget.ActionBar.Title">
<item name="android:textColor">#color/actionbar_text</item>
</style>
<!-- ActionBar tabs text styles -->
<style name="MyActionBarTabText"
parent="#android:style/Widget.Holo.ActionBar.TabText">
<item name="android:textColor">#color/actionbar_text</item>
</style>
</resources>
Apologies in advance if this sounds familiar, but I have tried everything I have seen from previous posts.
Happy to provide more details if needed. Thanks in advance.
Theme.Holo and Widget.Holo.ActionBar requires API Level 11
TextAppearance.Holo.Widget.ActionBar.Title and Widget.Holo.ActionBar.TabText requires API Level 13
Check your android:minSdkVersion. If it is less than 13 than you can't build your project(or you have to duplicate your styles for different API Levels, using different api level folders under res). eclipse shows this kind of errors.
And also your Android Project Build Target must be at least API Level 13.
