I've been trying this all evening to no avail so I'm going to list my exact steps starting from scratch.
This will be my project which I want to be able to create a grid layout on.
To set up the support package these are my steps:
android-sdks\extras\android\support\v7\gridlayout
testinggridlayout
project and click properties:At this point
If I go into the main.xml layout manually insert this code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<GridLayout
android:background="#FFFFFF"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:columnCount="8"
android:rowCount="5" >
</GridLayout>
</LinearLayout>
I get the error:
The following classes could not be found: - GridLayout (fix build path, edit XML).
If I change
<GridLayout> & </GridLayout>
to <android.support.v7.widget.GridLayout> & </android.support.v7.widget.Gridlayout>
I receive the same error:
The following classes could not be found: - android.support.v7.widget.GridLayout (fix build path, edit XML).
At that point I created a folder in my project called "libs".
I then copied the android-support-v7-GridLayout.jar file under libs in the GridLayout project to this folder.
I right clicked this file in my "libs" folder in "testinggridlayout" and selected "Add to Build Path".
My error then changed to:
The following classes could not be instantiated: - android.support.v7.widget.GridLayout (open class, show error log)
Which bit(s) have I missed out/ shouldn't have done?
I use intellij idea, so it's not exactly your case, but maybe it will be helpfull. I struggled with setting this up whole day, then it suddenly worked. I'll describe my setup so you can compare:
android-support-v13.jar
and android-support-v7-gridlayout.jar
. NOTE: I used the v7 support library in the main project, not the library project. In fact, checking it now - in library project I don't reference the v7 support.<android.support.v7.widget.GridLayout />
instead of <GridLayout />
xmlns:grid="http://schemas.android.com/apk/res-auto"
in your layout file to use custom attributes defined in the library project in your tag, like grid:columnCount
hope this helps. I'm currently trying it, not even sure it is something I need :)
If someone is having same problem here's a solution that worked for me:
After importing project into a workspace you need to add it as a dependency using Android tab and not Java Build Path
Project -> Properties -> Android -> Library -> [Add...]
I also ticked Is Library.
Copy android-support-v7-gridlayout.jar from the folder Android_SDK_folder\extras\android\support\v7\gridlayout\libs. Then, paste it in your project MyAndroidProject\libs folder.
