Hi,
I don't know why but when tapping the "calculate" button to store the
data calculated, when i goes to the listview the first time it tells
me that there is no data, when i tap again in the button i have all
datas displayed plus the last one!
Here is a video explanation:
http://www.4shared.com/video/Tdps8spN/problem.html
And here is the necessary code:
public class Saves extends Activity {
private Context context;
protected String[][] s;
protected String fileDir;
protected Activity activity;
private static AlertDialog alert_reset;
public void updatelv(Activity activity) {
SharedPreferences preferences =
PreferenceManager.getDefaultSharedPreferences(context);
String fileName = getResources().getString(R.string.fileName);
fileDir = "" + preferences.getString("login", "") + "."+
preferences.getString("marque", "") + ".";
s = myIO.ReadFilePerLine(getApplicationContext(),
fileDir+fileName);
ListView L = (ListView) findViewById(R.id.lv);
L.setAdapter(new ArrayAdapter<String>(this, R.layout.list_item,
s[0]));
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.histo);
context = getApplicationContext();
activity = this;
final SharedPreferences preferences = PreferenceManager
.getDefaultSharedPreferences(context);
String fileName = getResources().getString(R.string.fileName);
fileDir = "" + preferences.getString("login", "") + "."+
preferences.getString("marque", "") + ".";
s = myIO.ReadFilePerLine(getApplicationContext(), fileDir +
fileName);
updatelv(this);
ListView L = (ListView) findViewById(R.id.lv);
L.setTextFilterEnabled(true);
Thank you for your help.
