For some reason I cannot seem to update the color of the text in my ListView items. I'm not sure exactly why this is happening, does anyone have an idea?

XML:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"

    android:layout_height="fill_parent" >

    <ListView
        android:id="@+id/listView1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true" 
        android:textColor="@android:color/white"
        android:textSize="20sp">

    </ListView>

</RelativeLayout>

JAVA:

public class MainActivity extends Activity {
    Context context;
    ArrayList<String> aa = new ArrayList<String>();
        ListView lv;
        final String URL = "http://news.google.com";

        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            //setContentView(R.layout.activity_main);
            setContentView(R.layout.splash);
            lv= (ListView) findViewById(R.id.listView1);
            new MyTask().execute(URL);
        }

        private class MyTask extends AsyncTask<String, Void, String> {
            ProgressDialog prog;
            String title = "";

            @Override
            protected void onPreExecute() {
                prog = new ProgressDialog(MainActivity.this);
                prog.setMessage("Loading....");
                prog.show();
            }

            @Override
            protected String doInBackground(String... params) {
                try {
                    Document doc = Jsoup.connect(params[0]).get();
                    Element tableHeader = doc.select("tr").first();

                    for (Element element : tableHeader.children()) {
                        aa.add(element.text().toString());
                    }

                    title = doc.title();
                } catch (IOException e) {
                    e.printStackTrace();
                }
                return title;
            }

            @Override
            protected void onPostExecute(String result) {
                super.onPostExecute(result);
                prog.dismiss();
                ArrayAdapter<String> adapter = new ArrayAdapter<String>(MainActivity.this,android.R.layout.simple_list_item_1,aa);
                lv.setAdapter(adapter);
            }
        }
    }

Edit (in response to Philipp Jahoda's answer):

    @Override
    protected void onPostExecute(String result) {
        super.onPostExecute(result);
        prog.dismiss();
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(MainActivity.this, R.layout.custom_textview, aa);
        setContentView(R.layout.activity_main);
        lv = (ListView) findViewById(R.id.listView1);
        lv.setAdapter(adapter);
    }
}

And this code works just fine but color is the only problem? Because in your custom_textview you have linearlayout instead of textview, which arrayadapter expects textview. – Graphitize

You will need to create a custom layout for your ListView items where you set your desired textcolor.

In this way, you do not even need a custom-adapter.

e.g. custom_textview.xml

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/tv"
    android:textColor="@color/white"
    android:layout_width="fill_parent"
    android:gravity="center"
    android:layout_height="fill_parent"/>

Then, you can use your layout with the ArrayAdapter:

ArrayAdapter<String> adapter = new ArrayAdapter<String>(MainActivity.this, R.layout.custom_textview, aa);
lv.setAdapter(adapter);

Ok. I'm getting a Force Close issue when attempting this (I posted more details above just now) – Whaler
That is weird, I just tested the code, it works perfectly fine for me. – Vitrescent
Allright, I see your misstake: Your custom textview needs to be a TextView. It cant be a LinearLayout. Simply use the layout code I posted above for your ListView. – Vitrescent
Thanks! That fixed it... PS - I have another somewhat simple issue I'm stuck on if you'd like to take a shot at the correct answer :) #18904802 – Whaler
I already put the Textview to be the part of the ArrayAdapter constructor, .... and then how to change the color programatically ? @PhilippJahoda – Manganese

That's because android.R.layout.simple_list_item_1 use default text color, so the best way to do it is by making your own xml something like this: 

< TextView
android:id="@android:id/text1"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textColor="@android:color/white"
android:textSize="16sp"
/>

I dont have a textview in my source... I have a listview - are you sure this is correct? – Whaler
You need to create one and at ArrayAdapter<String> adapter = new ArrayAdapter<String>(MainActivity.this,R.layout.BLACK_TEXTVIEW,aa); change the black_textview for the one you made. – Showalter
@alvaro, and once you just create that textview on the xml, and then put it under arrayadapter constructor... and then... how to access it? I mean how to change the color itam one by one? – Manganese
@Manganese then you need to extends from arrayadapter, and in the method getView() do you logic. – Showalter

I had the same task where I only need to change the text color to white (since I have a dark background image) but would like to keep the default "simple_list_item_1" layout.

Answers above messed the layout for me, so I searched for original layout's xml and just added android:textColor="@android:color/white" at the end:

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/text1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:textAppearance="?android:attr/textAppearanceListItemSmall"
    android:gravity="center_vertical"
    android:paddingStart="?android:attr/listPreferredItemPaddingStart"
    android:paddingEnd="?android:attr/listPreferredItemPaddingEnd"
    android:paddingLeft="?android:attr/listPreferredItemPaddingLeft"
    android:paddingRight="?android:attr/listPreferredItemPaddingRight"
    android:minHeight="?android:attr/listPreferredItemHeightSmall"
    android:textColor="@android:color/white" />

Try android:textColor="#FFFFFF" instead.

His problem is not related to the color. – Vitrescent
This will not work. Use the accepted answer instead. – Battement
