Hi...
I have a problem when i'm passing value between activities....i'm using a
activity to get information from a database and put into a listview after
this I'm using a onListItemClick
to call the another activity to show the a details of the item I
selected...but when I put the key value of my item Id on Intent method
"putExtra" I cant get then into another acitivity...
what I'm doing wrong ?!
Thanks Igor
here my code:
first activity class (Restaurant.java)
public class Restaurants extends ListActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
try {
setContentView(R.layout.restaurants);
ListRestaurants();
} catch (Exception e) {
// TODO: handle exception
Log.e("oncreate resta",e.getMessage());
}
}
@Override
protected void onListItemClick(ListView l, View v, int position,
long id) {
// TODO Auto-generated method stub
//super.onListItemClick(l, v, position, id);
String[] FROM = {"_id","res_name", "res_city"};
Intent its = new
Intent().setClass(getBaseContext(),RestaurantsDetails.class);
DBAdapter dbAdapter = DBAdapter.getDBAdapterInstance(this);
try {
dbAdapter.createDataBase();
} catch (IOException e) {
// TODO: handle exception
Log.e("*** select ",e.getMessage());
}
dbAdapter.openDataBase();
Cursor c = dbAdapter.selectRecordsFromDB("restaurants",
FROM,null,null,null,null,null);
c.moveToPosition(position);
its.putExtra("Key",id);
startActivity(its);
}
public void ListRestaurants(){
DBAdapter dbAdapter =
DBAdapter.getDBAdapterInstance(this);
String[] FROM = {"_id","res_name", "res_city"};
int[] TO = {R.id._id,R.id.res_name,R.id.res_city};
try {
dbAdapter.createDataBase();
} catch (IOException e) {
// TODO: handle exception
Log.e("*** select ",e.getMessage());
}
dbAdapter.openDataBase();
Cursor c =
dbAdapter.selectRecordsFromDB("restaurants", FROM,null,null,null,null,null);
SimpleCursorAdapter sAdapter = new
SimpleCursorAdapter(this,R.layout.restaurant_row,c,FROM,TO);
setListAdapter(sAdapter);
dbAdapter.close();
}
}
//Second Activity
public class RestaurantsDetails extends Activity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
try {
setContentView(R.layout.restaurants_details);
Bundle extra = getIntent().getExtras();
if (extra != null) {
String mRowId = extra.getString("Key");
if (mRowId != null) {
TextView txtResId =
(TextView)findViewById(R.id.txtResId);
txtResId.setText(mRowId);
}
}
} catch (Exception e) {
// TODO: handle exception
Log.e("oncreate resta",e.getMessage());
}
}
}
