<p>{@link android.widget.TableLayout} is a {@link android.view.ViewGroup} that
|
|
displays child {@link android.view.View} elements in rows and columns.</p>
|
|
|
|
<ol>
|
|
<li>Start a new project named <em>HelloTableLayout</em>.</li>
|
|
<li>Open the <code>res/layout/main.xml</code> file and insert the following:
|
|
<pre>
|
|
<?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>
|
|
</pre>
|
|
<p>Notice how this resembles the structure of an HTML table. The {@link android.widget.TableLayout}
|
|
element is like the HTML <code><table></code> element; {@link android.widget.TableRow} is like
|
|
a <code>><tr>></code> 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.</p>
|
|
|
|
</li>
|
|
<li>Make sure your <em>HelloTableLayout</em> Activity loads this layout in the
|
|
{@link android.app.Activity#onCreate(Bundle) onCreate()} method:
|
|
<pre>
|
|
public void onCreate(Bundle savedInstanceState) {
|
|
super.onCreate(savedInstanceState);
|
|
setContentView(R.layout.main);
|
|
}
|
|
</pre>
|
|
<p>The {@link android.app.Activity#setContentView(int)} method loads the
|
|
layout file for the {@link android.app.Activity}, specified by the resource
|
|
ID — <code>R.layout.main</code> refers to the <code>res/layout/main.xml</code> layout
|
|
file.</p>
|
|
</li>
|
|
<li>Run the application.</li>
|
|
</ol>
|
|
<p>You should see the following:</p>
|
|
<img src="images/hello-tablelayout.png" width="150px" />
