here how add textviews gridview
gridview = (gridview) findviewbyid(r.id.gridview1); string[] arrayempty = new string[] {"", "", "", "", "", "", "", "", ""}; arraylist<string> listempty = new arraylist<string>(arrays.aslist(arrayempty)); gridview.setadapter(new arrayadapter<string>(this,r.layout.list_item,list)); here layout.xml

but need layout devices. maybe should use weights, don`t know how
here's trick: uniform table or grid, don't need tableview or gridview @ all. put inside linearlayout size=0 , layoutweight=1. size=0 seems counter-intuitive, combined layoutweight=1, has effect of giving child widgets exact same size, regardless of contents.
so this:
<!-- outer container; vertical layout fills screen --> <linearlayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <!-- first row --> <linearlayout android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="0dp" android:layout_weight="1"> <!-- contents of first row --> <!-- first item in first row --> <view android:layout_width="0dp" android:layout_height="fill_parent" android:layout_weight="1"> <!-- second item in first row --> <view android:layout_width="0dp" android:layout_height="fill_parent" android:layout_weight="1"> <!-- third item in first row --> <view android:layout_width="0dp" android:layout_height="fill_parent" android:layout_weight="1"> </linearlayout> <!-- second row --> <linearlayout android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="0dp" android:layout_weight="1"> <!-- contents of second row. --> <!-- etc --> </linearlayout> <!-- third row --> <linearlayout android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="0dp" android:layout_weight="1"> <!-- contents of third row --> <!-- etc --> </linearlayout> <button android:id="@+id/solvebutton android:layout_width="fill_parent" android:layout_width="wrap_content" /> <button android:id="@+id/clearbutton android:layout_width="fill_parent" android:layout_width="wrap_content" /> </linearlayout>
