Key classes

  1. {@link android.widget.TableLayout}
  2. {@link android.widget.TableRow}
  3. {@link android.widget.TextView}

{@link android.widget.TableLayout} is a {@link android.view.ViewGroup} that displays child {@link android.view.View} elements in rows and columns.

{@link android.widget.TableLayout} positions its children into rows and columns. TableLayout containers do not display border lines for their rows, columns, or cells. The table will have as many columns as the row with the most cells. A table can leave cells empty, but cells cannot span columns, as they can in HTML.

{@link android.widget.TableRow} objects are the child views of a TableLayout (each TableRow defines a single row in the table). Each row has zero or more cells, each of which is defined by any kind of other View. So, the cells of a row may be composed of a variety of View objects, like ImageView or TextView objects. A cell may also be a ViewGroup object (for example, you can nest another TableLayout as a cell).

The following sample layout has two rows and two cells in each. The accompanying screenshot shows the result, with cell borders displayed as dotted lines (added for visual effect). 

<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:stretchColumns="1">
    <TableRow>
        <TextView
            android:text="@string/table_layout_4_open"
            android:padding="3dip" />
        <TextView
            android:text="@string/table_layout_4_open_shortcut"
            android:gravity="right"
            android:padding="3dip" />
    </TableRow>

    <TableRow>
        <TextView
            android:text="@string/table_layout_4_save"
            android:padding="3dip" />
        <TextView
            android:text="@string/table_layout_4_save_shortcut"
            android:gravity="right"
            android:padding="3dip" />
    </TableRow>
</TableLayout>

Columns can be hidden, marked to stretch and fill the available screen space, or can be marked as shrinkable to force the column to shrink until the table fits the screen. See the {@link android.widget.TableLayout TableLayout reference} documentation for more details.

Example

  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="match_parent"
    android:layout_height="match_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 {@link android.widget.TableLayout} element is like the HTML <table> element; {@link android.widget.TableRow} is like a ><tr>> element; but for the cells, you can use any kind of {@link android.view.View} element. In this example, a {@link android.widget.TextView} is used for each cell. In between some of the rows, there is also a basic {@link android.view.View}, which is used to draw a horizontal line.

  3. Make sure your HelloTableLayout Activity loads this layout in the {@link android.app.Activity#onCreate(Bundle) onCreate()} method: 
    public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
}

    The {@link android.app.Activity#setContentView(int)} method loads the layout file for the {@link android.app.Activity}, specified by the resource ID — R.layout.main refers to the res/layout/main.xml layout file.

  4. Run the application.

You should see the following:
