title: Dynamically change LinearLayout height from wrap_content to fill_parent
body: <p>If someone can please tell me where I am going wrong here that would be awesome being I have put about 2 days into trying to figure (google) it out.  Basically I just want to change the layout_height of the root linearlayout from wrap_content to fill_parent when the user clicks a button.</p>
  
  <p>here is my root main.xml</p>
  
  <pre><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:id="@+id/mycontainer" 
  android:layout_width="fill_parent"
  android:layout_height="wrap_content"
  android:orientation="vertical" 
  android:background="#ffff00ff"&gt;
  
  &lt;Button android:id="@+id/listBtn" 
          android:layout_height="38dp"
          android:layout_width="wrap_content"
          android:text="List"
          android:onClick="listBtnHandler" 
          android:paddingLeft="17dp" 
          android:paddingRight="17dp" 
          android:layout_gravity="center" 
          android:layout_marginRight="10dip"/&gt;
  &lt;/LinearLayout&gt;
  </code></pre>
  
  <p>And here is my code that is triggering an error.</p>
  
  <pre><code>public class MainActivity extends Activity {
      /** Called when the activity is first created. */
  
  private Button listBtn;
  
      @Override
      public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.main);
  
      listBtn = (Button) findViewById(R.id.listBtn);
  
  }
  
  
  public void listBtnHandler(View v) {
      Log.i("eb", "my button worked");
  
      LinearLayout ll = (LinearLayout) findViewById(R.id.mycontainer);
  
      ll.setLayoutParams(new LayoutParams(ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.FILL_PARENT));
  
  
  
      //ViewGroup.LayoutParams params = ll.getLayoutParams();
      //params.height=300;
  
      //ll.setLayoutParams(new LinearLayout.LayoutParams(params));
  
      //ll.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.FILL_PARENT));
  
  }
  </code></pre>
  
  <p>}</p>
  
  <p>Needless to say I can't get anything to work here.</p>
  
  <p>Here is the console output and it doesn't show anything relevant since I get a source not found.</p>
  
  <pre><code>Application already deployed. No need to reinstall.
