You must supply a resource ID for a TextView

[rpysork]

I am getting an error message in logcat after the Sunshine app fails to open in my Nexus emulator that shuts down.

The error message causes the application to crash with a fatal exception:
05-04 17:59:12.130 2388-2388/com.example.android.sunshine.app E/AndroidRuntime: FATAL EXCEPTION: main
Process: com.example.android.sunshine.app, PID: 2388
java.lang.IllegalStateException: ArrayAdapter requires the resource ID to be a TextView

I have written the code according to the example provided here: 1.04_add_dummy_data...1.05_create_arrayadapter

My code is as follows:

package com.example.android.sunshine.app;

import android.support.v7.app.ActionBarActivity;
import android.support.v4.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;

public class MainActivity extends ActionBarActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    if (savedInstanceState == null) {
        getSupportFragmentManager().beginTransaction()
                .add(R.id.container, new PlaceholderFragment())
                .commit();
    }
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) {
        return true;
    }

    return super.onOptionsItemSelected(item);
}

/**
 * A placeholder fragment containing a simple view.
 */
public static class PlaceholderFragment extends Fragment {

    ArrayAdapter<String> mForecastAdapter;

    public PlaceholderFragment() {
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {

        //Create some dummy data for the ListView. Here's a sample weekly forecast
        String[] forecastArray = {
                "Today - Sunny - 88/63",
                "Tomorrow - Foggy - 70/40",
                "Weds - Cloudy - 72/63",
                "Thurs - Hemorrhoids - 75/65",
                "Fri - Heavy Rain - 65/56",
                "Sat - Flooding Get Out the Boat - 60/55",
                "Sun - Sunny - 80/72"
        };

        List<String> weekForecast = new ArrayList<String>(Arrays.asList(forecastArray));

        // Now that we have some dummy forecast data, create an ArrayAdapter.
        //The ArrayAdapter will take data from a source (like our dummy forecast data) and
        //use it to populate the ListView it's attached to.

        mForecastAdapter = new ArrayAdapter<String>(
                //The current context (this activity)
                getActivity(),
                //ID of List item layout
                R.layout.list_item_forecast,
                //ID of the textview to populate
                R.id.list_item_forecast_textview,
                //Forecast data
                weekForecast);

        View rootView = inflater.inflate(R.layout.fragment_main, container, false);

        // Get a reference to the ListView, and attach this adapter to it.
        ListView listView = (ListView) rootView.findViewById(R.id.listview_forecast);
        listView.setAdapter(mForecastAdapter);

        return rootView;
    }

}

}

Can anyone tell me what I'm doing wrong.
If by any chance I have forgotten something please reply with what additional information is needed.
