Iterate through rows from Sqlite-query
I have a table layout that I want to populate with the result from a database query. I use a select all and the query returns four rows of data.
I use this code to populate the TextViews inside the table rows.
Cursor c = null;
c = dh.getAlternative2();
startManagingCursor(c);
// the desired columns to be bound
String[] columns = new String[] {DataHelper.KEY_ALT};
// the XML defined views which the data will be bound to
int[] to = new int[] { R.id.name_entry};
SimpleCursorAdapter mAdapter = new SimpleCursorAdapter(this,
R.layout.list_example_entry, c, columns, to);
this.setListAdapter(mAdapter);
I want to be able to separate the four different values of KEY_ALT, and choose where they go. I want them to populate four different TextViews instead of one in my example above.
How can I iterate through the resulting cursor?
Cursor
objects returned by database queries are positioned before the first entry, therefore iteration can be simplified to:
while (cursor.moveToNext()) {
// Extract data.
}
Reference from SQLiteDatabase
.
You can use below code to go through cursor and store them in string array and after you can set them in four textview
String array[] = new String[cursor.getCount()];
i = 0;
cursor.moveToFirst();
while (!cursor.isAfterLast()) {
array[i] = cursor.getString(0);
i++;
cursor.moveToNext();
}
for (boolean hasItem = cursor.moveToFirst(); hasItem; hasItem = cursor.moveToNext()) {
// use cursor to work with current item
}
