Hi!
I'm trying to change height layout from "wrap_content" to
"fill_parent" from code. Using landscape mode.
public class BBB extends Activity
{
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.bbb);
LinearLayout layout =
(LinearLayout)findViewById(R.id.mainZZZ);
LayoutParams params = new LayoutParams
(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
layout.setLayoutParams(params);
}
}
I have bbb.xml layout file
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/
android"
android:orientation="vertical"
android:id="@+id/mainZZZ"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
</LinearLayout>
Why the activity can't be loaded after run-time changes?
Missing I something?
Thanks in advance,
Evgeny
