Android :: Binding Data From Database To Checkbox In ListView?
Oct 1, 2009
I'm trying to bind data from my SQLiteDatabase to a ListView. I'm currently using a SimpleCursorAdapter to fill in my ListView. Unfortunately this doesn't seem to work with setting a CheckBox's checked attribute. This is how I do it now; instead of changing the CheckBox's checked status the adapter is filling in the value to the text argument, so the value is displayed right of the CheckBox as text.
Java:
setListAdapter( new SimpleCursorAdapter( this, R.layout.mylist, data,
new String[] { Datenbank.DB_STATE, Datenbank.DB_NAME }, new int[] { R.id.list_checkbox, R.id.list_text } ) );
mylist.xml:
<?xml version="1.0" encoding="utf-8"?> <LinearLayout android:id="@+id/LinearLayout01"
android:layout_width="fill_parent" android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android" >
<CheckBox android:text="" android:id="@+id/list_checkbox"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:checked="false" > </CheckBox>
<TextView android:text="" android:id="@+id/list_text" android:layout_width="wrap_content"
android:layout_height="wrap_content" > </TextView> </LinearLayout>
The field in the database is of course of type boolean and I've also tried to assign an id to the checked field to fill the value in.

I think I've tried everything(made focusable:false!!) and I cant capture in anyway the selected checkbox on my list item. Even OnItemClickListener, doesn't respond to any click. How can I retrieve checked checkboxes in my list item? My list item included: image view, 4 textviews and the checkbox. Some code:
this is in my ListActivity class:
final String columns[] = new String[] { MyUsers.User._ID, MyUsers.User.MSG, MyUsers.User.LOCATION }; int[] to = new int[] { R.id.toptext, R.id.bottomtext,R.id.ChkBox, R.id.Location}; Uri myUri = Uri.parse("content://com.idan.datastorageprovider/users"); Cursor cursor = getContentResolver().query(myUri, columns, null, null, null); startManagingCursor(cursor); ListCursorAdapter myCursorAdapter=new ListCursorAdapter(this, R.layout.listitem, cursor, columns, to); this.setListAdapter(myCursorAdapter);
And this is my Custom Cursor adapter class:
public class ListCursorAdapter extends SimpleCursorAdapter { private Context context; private int layout; public ListCursorAdapter(Context context, int layout, Cursor c, String[] from, int[] to) { super(context, layout, c, from, to); this.context = context; this.layout = layout;
} @Override public View newView(Context context, Cursor cursor, ViewGroup parent) { Cursor c = getCursor(); final LayoutInflater inflater = LayoutInflater.from(context); View v = inflater.inflate(layout, parent, false); return v;
} @Override public void bindView(View v, Context context, Cursor c) { TextView topText = (TextView) v.findViewById(R.id.toptext); if (topText != null) { topText.setText("");
} int nameCol = c.getColumnIndex(MyUsers.User.MSG); String name = c.getString(nameCol); TextView buttomTxt = (TextView) v.findViewById(R.id.bottomtext); if (buttomTxt != null) { buttomTxt.setText("Message: "+name); } nameCol = c.getColumnIndex(MyUsers.User.LOCATION);
name = c.getString(nameCol); TextView location = (TextView) v.findViewById(R.id.Location);
if (locationLinkTxt != null) { locationLinkTxt.setText(name);
}
I've tried many ways. many listeners, can't figure how to capture listener to my checkboxes. The data I am binding to the list items from the database, isn't concerned about the checkbox.. only the textviews. There isn't any connection between the database and the checkbox I have in the list's item.
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="100sp" android:focusable="false" android:focusableInTouchMode="false"> android:padding="6dip">

android:orientation="vertical" android:layout_width="1sp"
android:layout_height="fill_parent" android:layout_weight="1"

</TextView> </LinearLayout>

I currently building an android apps that retrieve data from a distant Web service and I search an efficient way to bind data form XML to ListView. I already use CursorAdapter and i search on the web for an "XmlAdapter". I read on Google IO topic "Coding for Life - Battery Life, That Is" (http://code.google.com/events/io/sessions/ CodingLifeBatteryLife.html) that is more efficient to use "stream parser" instead of "tree parser" but I don't find the way to build a class that implement ListAdapter because of stream parser can't navigate backward so I don't understand how implement method that use "position" parameter (How retrieve data before current XML Parser position?).

Where could I find any examples of rendering XML data in a ListView? i.e, the model is read from a XML file, not in an existing array or database cursors.

I have the following code to intantiate a SimpleCursorAdapter to use with a ListView. As you can see I have passed the R.layout.log_item to display the list items, and one value/control to bind to (TripDate).
SimpleCursorAdapter sca = new SimpleCursorAdapter(this, R.layout.log_item,c,new String[] {DBAdapter.KEY_LOG_TRIPDATE},new int[]{R.id.txtTripDate});
This works. I currently only have one widget in the layout xml, a TextView to hold the TripDate.
How do I pass multiple binding parameters for the additional widgets in the layout? So I can also display other info.

I kind of have a 2 part question here.
1) How can I populate my ListView so that strings are what is displayed, but when items are selected, a non-visible id value (contact id from phone contacts) is the value that is actually used?
2) I have a ListView that's using multipleChoice mode for item selections. It's popluated with names from my contacts list. When I select an item in the ListView, I want that selected item to trigger a call to my SqLite routine to store the value into a database record. How do I make this event fire when an item is checked in the listview?I had hoped to be able to use something like the onClick event for each checked item, but have made not one bit of progress.

I'm sure this is an obvious one but I'm at a loss. I'm using my own layout for list rows, all well and fine. but the moment I add a checkbox view to the rows layout only the checkbox responds to user selection. I'd like for the checkbox to change state if the user taps anywhere within a given row. (as with android prefs)

I cant find a way to save the checkbox state when using a Cursor adapter. Everything else works fine but if i click on a checkbox it is repeated when it is recycled. Ive seen examples using array adapters but because of my lack of experience im finding it hard to translate it into using a cursor adapter. Could someone give me an example of how to go about it.code...

I need to be able to scroll through a list with (up to) 20K rows, backed by a cursor on a read-only db. Testing 20K rows on a G1, the query takes approx .02s regardless of table size, while binding the adapter to the list takes 4.5s. Note that this is before the view calls used in rendering. What makes the binding delay more troublesome is that it blocks the UI thread, and is incurred on every rotate. Combine these, and doing a rotate just after starting the bind results in a delay up to 9s.
I tried lazy loading with a base adapter, but that hits the same delay in the underlying cursor.getCount(), and the overall user experience isn't ideal. I also considered using an ArrayAdapter, adding synthesized objects from the cursor rows, but then I'd incur the overhead of creating up to 20K objects (not to mention the additional memory requirements).

I'm populating a listview from a database query and I can't seem to figure out what is going wrong.
As you will see in the image, the query is returning some sort of id. I've done a ton of googling, but the problem is that I don't know what to search!
