You can always create layouts programatically, and it is also possible to
add widgets programatically to the layouts declared in xml files.
All widgets provide constructors which you can use to create them
programatically..There are methods corresponding to each xml attribute for
any widget, so you can set properties programatically. Check out the
documentation on widgets for those.
For example, you can add a TextView to your xml declared layout as follows:
LinearLayout l = (LinearLayout)findViewById(R.id.widget27);
TextView label = new TextView(this);
label.setText(test);
l.addView(label, new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.FILL_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT));
Hope that helps.

Ok I want to be able to create a widget dynamically after a
setContentView. Here is what I have so far:
public class Demo extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.main);
}
}
?xml version=1.0 encoding=utf-8?
LinearLayout
android:id=@+id/widget27
android:layout_width=fill_parent
android:layout_height=fill_parent
xmlns:android=http://schemas.android.com/apk/res/android;
android:orientation=vertical
Button
android:id=@+id/widget28
android:layout_width=wrap_content
android:layout_height=wrap_content
android:text=Hit me!
/Button
/LinearLayout
Now after the line:
setContentView(R.layout.main);
can I add another button to the LinearLayout? How do I do this? This
is an oversimplification of what I want to do, hence the question
might sound silly.
If this is not possible, how can I create the above UI represented by
the XML file programmatically?
