this will help Look at the Java API: http://docs.oracle.com/javase/7/docs/api/java/awt/GridLayout.html Here is a small example from the Java API:
code :
import java.awt.*;
import java.applet.Applet;
public class ButtonGrid extends Applet {
     public void init() {
         setLayout(new GridLayout(3,2));
         add(new Button("1"));
         add(new Button("2"));
         add(new Button("3"));
         add(new Button("4"));
         add(new Button("5"));
         add(new Button("6"));
     }
 }

it fixes the issue
scrollPane.setLayout(new GridLayout(0,4)); //Line which causes the error
code :
JPanel panel = new JPanel( new GridLayout(0, 4) );
panel.add( component1 );
panel.add( component2 );
panel.add( component3 );
panel.add( component4 );
JScrollPane = new JScrollPane( panel );

this will help I am using a GridView in GridLayout. But it is getting extended below the device's height. Any particular reason for it?? I have searched everywhere for similar issue but haven't found anything yet. , Use "android:layout_below" like this:
code :
<GridLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/gridLayout1"
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:stretchMode="spacingWidthUniform"
        android:gravity="center"
        android:rowCount="6"
        android:columnCount="2"
        android:layout_below="@id/headerRelativeLayout">

    <GridView
        android:id="@+id/gridView"
        android:numColumns="auto_fit"
        android:gravity="center"
        android:stretchMode="columnWidth"
        android:layout_width="fill_parent"
        android:layout_height="match_parent"
        android:layout_columnSpan="2"
        android:layout_row="4"
        android:layout_column="0" />

 </GridLayout>

To fix the issue you can do Grid View : It is is a ViewGroup that displays items in a two-dimensional, scrollable grid. In this each Grid is of same size (Height and width). Grid View shows symmetric items in view.

wish of those help Whenever I want to find my grid layout by ID my app crashes immediately upon starting. It is not a typo (I don't get any compiling errors). , I had to change casting from this:
code :
GridLayout gridLayout = findViewById(R.id.gridLayout);
android.support.v7.widget.GridLayout gridLayout = findViewById(R.id.gridLayout);

fixed the issue. Will look into that further Just debugged a similar situation, turned out the two-dimensional array being used to setup the support-GridLayout was too large for all the 2.3.x devices I tested. Dropped the max number of rows down and StackOverflowError avoided. Hope this information helps your case!
