Android Android Lists and Adapters (2015) Standard ListViews Using a Default Adapter

Error when setting adapter

Hello,

I am having trouble running this app. Every time I press the '7 DAY' button, I get a pop-up saying "Unfortunately, Stormy has stopped.". The error was:

java.lang.IllegalStateException: ArrayAdapter requires the resource ID to be a TextView

I still couldn't figure out what the problem was, here is my code:

package com.diego.stormy.ui;

import android.app.ListActivity;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.ArrayAdapter;
import com.diego.stormy.R;

public class DailyForecastActivity extends ListActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_daily_forecast);

        String[] daysOfTheWeek = { "Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday" };
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
                android.R.layout.activity_list_item,
                daysOfTheWeek);
        setListAdapter(adapter);
    }
}

Please help!

Hi Diego - Change:

android.R.layout.activity_list_item

to:

android.R.layout.simple_list_item_1

Hello, I notice that the second parameter you pass when constructing the array adapter is different to that in the video. You are passing:

android.R.layout.activity_list_item

Try passing:

android.R.layout.simple_list_item_1
