You have to make sure not just to use
<android.support.v7.widget.GridLayout> for the layout itself, but you have
to use the app namespace for all of its attributes too, since "layout_row",
"rowCount" etc are not defined in the android namespace for versions older
than API 14. As of ADT 17 there's improved handling for library project
resource namespaces ("res-auto"), so your layout should look something like
this:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.GridLayout
xmlns:android="http://schemas.android.com/apk/res/android";
xmlns:app="http://schemas.android.com/apk/res-auto"; <==== the
namespace used for the library project
android:layout_width="match_parent"
android:layout_height="match_parent"
app:columnCount="6" > <===== notice how we're using app:columnCount
here, not android:columnCount!
<Button
android:id="@+id/button1"
app:layout_column="1" <=== again, note the app: namespace
app:layout_columnSpan="2"
app:layout_gravity="left"
app:layout_row="1"
android:text="Button" />
<CheckBox
android:id="@+id/checkBox1"
app:layout_column="4"
app:layout_gravity="left"
app:layout_row="2"
android:text="CheckBox" />
<Button
android:id="@+id/button2"
app:layout_column="5"
app:layout_gravity="left"
app:layout_row="3"
android:text="Button" />
<android.support.v7.widget.Space <=== space widgets also need the
full support package path
android:layout_width="21dp" <=== use the android namespace for
width, height etc -- only use app: for the grid layout library's new
resources
android:layout_height="1dp"
app:layout_column="0"
app:layout_gravity="fill_horizontal"
app:layout_row="0" />
