Answer 1

Instead of creating the layout in XML, I decided to do it in code. The file a is a single drop in replacement in your code.

package com.stackoverflow.free.examples;

import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.view.View;
import android.widget.AdapterView;
import android.widget.LinearLayout;
import android.widget.ListAdapter;
import android.widget.ListView;
import android.widget.TableRow;
import android.widget.TextView;

public class SupportListActivity extends ActionBarActivity {
    protected ListAdapter mAdapter;
    protected ListView mList;
    protected TextView mEmptyMessage;

    @Override
    protected void onCreate(Bundle savedBundle)
    {
        super.onCreate(savedBundle);
        mEmptyMessage = new TextView(this);
        mEmptyMessage.setText("No results");
        mList = new ListView(this);
        mList.setEmptyView(mEmptyMessage);
        LinearLayout ll = new LinearLayout(this);
        ll.addView(mEmptyMessage, TableRow.LayoutParams.MATCH_PARENT, TableRow.LayoutParams.MATCH_PARENT);
        ll.addView(mList, TableRow.LayoutParams.MATCH_PARENT, TableRow.LayoutParams.MATCH_PARENT);
        setContentView(ll);
    }

    public void setListAdapter(ListAdapter adapter) {
        synchronized (this) {
            mAdapter = adapter;
            mList.setAdapter(adapter);
        }
    }

    /**
     * Get the activity's list view widget.
     */
    public ListView getListView() {
        return mList;
    }

    /**

     * position with the adapter's data

        mList.setSelection(position);
    }
