Adding Views to XML layout in Java
<p>I already have an XML layout with some buttons in it, and now i want to add a textview to the same layout, but in my Java class. I don't get any errors until the "addView" line. I would also appreciate it if someone could tell me a better way to add onto a pre-existing XML layout in Java.  </p>

<pre><code>public class MyActivity extends Activity{
TextView textview;
RelativeLayout layout;


@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
layout=(RelativeLayout)findViewById(R.id.mylayout); 
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParam(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, RelativeLayout.TRUE);
textview=new TextView(this);
textview.setId(16);
textview.setText("Help");
layout.addView(textview, params);
setContentView(layout);
}
</code></pre>
