Android：使用ListActivity在同一活动上创建文本字段显示

Question

I have an activity that pulls a String Array from xml and displays a ListActivity (the class extends ListActivity) and I'd like to know if it is possible to also display a textfield or textView below the list?

If so, what method should I research to do this? Have code samples?

Thanks!

CODE:

public class txchl extends ListActivity {
/** Called when the activity is first created. */
public void onCreate(Bundle icicle) {
    super.onCreate(icicle);
    //setContentView(R.layout.main);
    String[] rmenu = getResources().getStringArray(R.array.root_menu);
    if (rmenu != null) {
        setListAdapter(new ArrayAdapter<String>(this, R.layout.list_item, rmenu));
    }
    TextView tv = new TextView(this);
    tv.setText("Hello");
    setContentView(tv);
}
@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
    super.onListItemClick(l, v, position, id);
    //
    if (position == 4 || position == 5) {
        Intent myIntent = new Intent(v.getContext(), Activity2.class);
        myIntent.putExtra("com.activity.Key", position);
        startActivity(myIntent);
    } else {
        Intent myIntent = new Intent(v.getContext(), txchl_hb.class);
        myIntent.putExtra("com.activity.Key", position);
        //myIntent.putExtra("com.activity.Dir", directives[position]);
        startActivity(myIntent);
    }
}

}

What you want is a vertical LinearLayout that contains a ListView and a TextView

There is an example of what you want to achieve in the android reference:

ListActivity has a default layout that consists of a single, full-screen list in the center of the screen. However, if you desire, you can customize the screen layout by setting your own view layout with setContentView() in onCreate(). To do this, your own view MUST contain a ListView object with the id "@android:id/list" (or list if it's in code)

http://developer.android.com/reference/android/app/ListActivity.html

<?xml version="1.0" encoding="utf-8"?>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
         android:orientation="vertical"
         android:layout_width="match_parent"
         android:layout_height="match_parent"
         android:paddingLeft="8dp"
         android:paddingRight="8dp">

     <ListView android:id="@id/android:list"
               android:layout_width="match_parent"
               android:layout_height="match_parent"
               android:background="#00FF00"
               android:layout_weight="1"
               android:drawSelectorOnTop="false"/>

     <TextView android:id="@id/android:empty"
               android:layout_width="match_parent"
               android:layout_height="match_parent"
               android:background="#FF0000"
               android:text="No data"/>
 </LinearLayout>
