zu bekommen Ich versuche, eine einfache SMS-App zu erstellen, für die Bearbeitungsseite alle gespeicherten SMS auflistet. Ich habe 2 Buttons in meinem Layout für Bearbeiten und Löschen, aber wenn ich auf sie klicke, kann ich die Zeilennummer (Zeilennummer von oben) nicht abrufen, um die SMS zu dieser bestimmten Zeile abzurufen. Jemand bitte helft mir ... meine SMS Adapter erweitert nicht nicht anything..Here meiner Klasse und xML-Dateien ..Nicht in der Lage, die Nummer der angeklickte Zeile in der Listenansicht von Android
public class SMSEdit extends ListActivity{
private SMSDbAdapter mDbHelper;
//private Button editsmsbtn, deletesmsbtn;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.editsmslist);
mDbHelper = new SMSDbAdapter(this);
mDbHelper.open();
fillData();
}
public void fillData() {
Cursor smsCursor = mDbHelper.fetchAllNotes();
startManagingCursor(smsCursor);
// Create an array to specify the fields we want to display in the list (only TITLE)
String[] from = new String[]{SMSDbAdapter.KEY_TITLE,
SMSDbAdapter.KEY_BODY,
SMSDbAdapter.KEY_DATE,
SMSDbAdapter.KEY_TIME};
// and an array of the fields we want to bind those fields to (in this case just text1)
int[] to = new int[]{R.id.smseditlistTO,
R.id.smseditlistMessage,
R.id.smseditlistDay,
R.id.smseditlistTime};
// Now create a simple cursor adapter and set it to display
SimpleCursorAdapter smsadap =
new SimpleCursorAdapter(this, R.layout.smsrow, smsCursor, from, to);
setListAdapter(smsadap);
}
public void myEditClickHandler(View v)
{
//get the row the clicked button is in
LinearLayout vwParentRow = (LinearLayout)v.getParent();
Button btnChild = (Button)vwParentRow.getChildAt(4);
btnChild.setText("I've been clicked!");
ListAdapter pos = getListAdapter();
Intent intent = new Intent();
intent.setClass(SMSEdit.this, SMS.class);
// intent.putExtra(SMSDbAdapter.KEY_ROWID, id);
startActivity(intent);
finish();
}
public void myDeleteClickHandler(View v)
{
//get the row the clicked button is in
LinearLayout vwParentRow = (LinearLayout)v.getParent();
//TextView child = (TextView)vwParentRow.getChildAt(0);
Button btnChild = (Button)vwParentRow.getChildAt(5);
//btnChild.setText(child.getText());
btnChild.setText("I've been clicked!");
int c = Color.CYAN;
vwParentRow.setBackgroundColor(c);
vwParentRow.refreshDrawableState();
}
