My Class extends ListActivity</p> <p>how do I? thanks in advance</p> <p>FULL CODE:</p> <pre><code>public class ProvaDatabase extends ListActivity{ TextView sts; private DatabaseHelper databaseHelper; @Override public void onCreate(Bundle savedInstanceState) { sts = (TextView) findViewById(R.id.stato); sts.setTextColor(android.graphics.Color.GREEN); //sts.setTextColor(Color.rgb(12,255,0)); super.onCreate(savedInstanceState); databaseHelper = new DatabaseHelper(this); SQLiteDatabase db = databaseHelper.getWritableDatabase(); databaseHelper.insertdb(db, "sta", "25/11/2016", "SUCCESS", null, null, null); databaseHelper.insertdb(db, "ssis", "25/11/2016", "WAITING", null, null, null); databaseHelper.insertdb(db, "AAAAAAAA", "25/11/2016", "FAILED", null, null, null); databaseHelper.insertdb(db, "BBBB", "bBBBBBB", "SUCCESS", null, null, null); Cursor c = databaseHelper.getDB(); startManagingCursor(c); setListAdapter(new SimpleCursorAdapter(this, R.layout.registryvista, c, new String[] { TabellaRegistry.TYPE, TabellaRegistry.DATE, TabellaRegistry.STATUS }, new int[] { R.id.tipo, R.id.data, R.id.stato })); setContentView(R.layout.main2); </code></pre>

    2. COMore than likely sts is null when you try to set the color. Are you sure you are setting the content view for the activity you are in?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
