Table Layout

TableLayout is a ViewGroup that displays child View elements in rows and columns.

  1. Start a new project named HelloTableLayout.
  2. Open the 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.

  3. Make sure your HelloTableLayout Activity loads this layout in the 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.

  4. Run the application.
