TableLayout
is a ViewGroup
that
displays child View
elements in rows and columns.
res/layout/main.xml
file and insert the following:
<?xml version="1.0" encoding="utf-8"?> <TableLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:stretchColumns="1"> <TableRow> <TextView android:layout_column="1" android:text="Open..." android:padding="3dip" /> <TextView android:text="Ctrl-O" android:gravity="right" android:padding="3dip" /> </TableRow> <TableRow> <TextView android:layout_column="1" android:text="Save..." android:padding="3dip" /> <TextView android:text="Ctrl-S" android:gravity="right" android:padding="3dip" /> </TableRow> <TableRow> <TextView android:layout_column="1" android:text="Save As..." android:padding="3dip" /> <TextView android:text="Ctrl-Shift-S" android:gravity="right" android:padding="3dip" /> </TableRow> <View android:layout_height="2dip" android:background="#FF909090" /> <TableRow> <TextView android:text="X" android:padding="3dip" /> <TextView android:text="Import..." android:padding="3dip" /> </TableRow> <TableRow> <TextView android:text="X" android:padding="3dip" /> <TextView android:text="Export..." android:padding="3dip" /> <TextView android:text="Ctrl-E" android:gravity="right" android:padding="3dip" /> </TableRow> <View android:layout_height="2dip" android:background="#FF909090" /> <TableRow> <TextView android:layout_column="1" android:text="Quit" android:padding="3dip" /> </TableRow> </TableLayout>
Notice how this resembles the structure of an HTML table. The TableLayout
element is like the HTML <table>
element; TableRow
is like
a ><tr>>
element;
but for the cells, you can use any kind of View
element. In this example, a
TextView
is used for each cell. In between some of the rows, there is also a
basic View
, which is used to draw a horizontal line.
onCreate()
method:
public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); }
The setContentView(int)
method loads the
layout file for the Activity
, specified by the resource
ID — R.layout.main
refers to the res/layout/main.xml
layout
file.
