I'm trying to do a list getting the data from y sqlite db using a custom CursorAdaptor to show an image an some data to the right, but so far all I got was a blank screen or a spinning loading circle without a result.
Here is my fragment activity:
public class FragMvp extends SherlockListFragment {
private DataBaseManager dataBase;
private MyCursorAdapter mAdapter;
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
// creates and open the database so we can use it
dataBase = DataBaseManager.instance();
String query = "SELECT mo._id,mo.sprite,mo.iName FROM Mobs AS mo WHERE mo.MobType = 2 ORDER BY mo.iName ASC;";
Cursor cursor = dataBase.select(query);
if (cursor != null) {
mAdapter = new MyCursorAdapter(ApplicationContextProvider.getContext(), cursor, false);
setListAdapter(mAdapter);
cursor.close();
}
}
#Override
public void onListItemClick(ListView l, View v, int position, long id) {
// Do something with the data
}
}
The query is working perfectly on my database manager and if I use an ArrayAdapter, it works and shows data. So I guess that the problem is not database related.
Then, here is the CursorAdapter:
public class MyCursorAdapter extends CursorAdapter {
private final LayoutInflater mInflater;
public MyCursorAdapter(Context context, Cursor c, boolean autoRequery) {
super(context, c, autoRequery);
mInflater = LayoutInflater.from(context);
mContext = context;
}
#Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
return mInflater.inflate(R.layout.my_adapter, parent, false);
}
#Override
public void bindView(View view, Context context, Cursor cursor) {
String mobSprite = cursor.getString(cursor.getColumnIndex("sprite"));
String mobName = cursor.getString(cursor.getColumnIndex("iName"));
int lvl = cursor.getInt(cursor.getColumnIndex("LVL"));
String hp = cursor.getString(cursor.getColumnIndex("HP"));
ImageView imageView = (ImageView) view.findViewById(R.id.mobSprite);
TextView mobNameView = (TextView) view.findViewById(R.id.mobName);
TextView levelView = (TextView) view.findViewById(R.id.lvl);
TextView hpView = (TextView) view.findViewById(R.id.hp);
int resID = context.getResources().getIdentifier(mobSprite, "drawble", context.getPackageName());
imageView.setImageResource(resID);
mobNameView.setText(mobName);
levelView.setText(lvl);
hpView.setText(hp);
}
}
And the XML just in case. It's not finished yet, but first I want to see some results and see how they look.

I don't know where is the problem, I've look for countless of tutorials and it's always the same. Do the CursorAdapter, pass it the cursor and context and set the listAdapter... but it's not working.
The problem is here.
Cursor cursor = dataBase.select(query);
if (cursor != null) {
mAdapter = new MyCursorAdapter(ApplicationContextProvider.getContext(), cursor, false);
setListAdapter(mAdapter);
cursor.close(); <========
}
You are closing the cursor prematurely. If you close it here, the Adapter will have zero results. The CursorAdapter will take care of closing the cursor when it is done or when you change the cursor to a new one.
Hope this helps.

I'm trying to add left and right swipe to listview for creating calling intent and messaging intent like contacts app :
swipe right -> call
swipe left -> message
OnSwipe, it should call an intent
I'm trying lot of ways to do i'm unable get the solution
Here is my code below for spanning list View items(excluding swipe related code because i use libraries till now):
This is my adpater class
class ContactCursorAdapter extends CursorAdapter{
public ContactCursorAdapter(Context context, Cursor c) {
super(context, c, 0);
}
#Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
return LayoutInflater.from(context).inflate(R.layout.contacts_list_item, parent, false);
}
#Override
public void bindView(View view, Context context, Cursor cursor) {
TextView nameTextView = (TextView) view.findViewById(R.id.text_view_name);
ImageView profilePictureView = (ImageView) view.findViewById(R.id.image_person);
int columnNameIndex = cursor.getColumnIndex(ContactEntry.COLUMN_PERSON_NAME);
int columnNumberIndex = cursor.getColumnIndex(ContactEntry.COLUMN_CONTACT_NUMBER);
int profilePictureIndex = cursor.getColumnIndex(ContactEntry.COLUMN_PROFILE_PICTURE);
String contactName = cursor.getString(columnNameIndex);
final String contactNumber = cursor.getString(columnNumberIndex);
byte[] profilePicture = cursor.getBlob(profilePictureIndex);
if (contactName.length() == 0) {
nameTextView.setText(contactNumber);
} else {
nameTextView.setText(contactName);
}
if (profilePicture != null) {
if (profilePicture.length > 3) {
profilePictureView.setImageBitmap(BitmapFactory.decodeByteArray(profilePicture, 0, profilePicture.length));
} else {
profilePictureView.setImageResource(R.drawable.ic_person);
}
}
}
This is my contact list item file

I want to use CursorAdapter only
I have a Fragment class that can display everything in my database in a ListView, and I have an inner class that extends SimpleCursorAdapter to use buttons within my ListView.
So in each element of my list view, I have several TextView's and 2 button. With my following code, I can use a button listener for a button inside my ListView. But inside my listener, I want to get the content of the TextView inside the same element that the button I click on. But When I click on a button to display my TextView, it display the last element of my ListView and I don't know why !
For example if I have 3 elements in my ListView like this :
_id = 1, name = "bob"
_id = 2, name = "john"
_id = 3, name = "bobby"
Each of these element are displayed with a button to display there ID, but if I click on the button inside bob, I get "id = 3". Same for john and bobby. And if I had a new element, I get his ID
My listener is in the bind function in my inner class MySimpleCursorAdapter.
Here is my Fragment Class :
public class ViewCardEditor extends Fragment implements LoaderManager.LoaderCallbacks<Cursor> {
public static final String authority = "com.example.jean.cartememoire.CardContentProvider";
public String[] from;
public final int[] to = {R.id.idList, R.id.themeList, R.id.questionList, R.id.reponseList, R.id.difficultList};

stock.DIFFICULTE};
// Inflate the layout for this fragment
if (container != null) {

Thank you for help !
Probably vh.idList is containing last item view which is provided by last call of newView .
Get clicked row item id using findViewById and v parameter of onClick method:
public void onClick(View v) {
View parentView = (View)v.getParent();
TextView idList = parentView.findViewById(R.id.idList);
int id = Integer.parseInt(idList.getText().toString());
...
}

i want to set numbering in tvSlNo.
please help
In your getView() method of your listViewAdapter simply use the position variable and set it on your TextView. You may need to add 1 to the position since it starts with 0. So use (position+1) and then set it to your TextView
Though this question may be too late but for other reference purposes.
Check where you have this code: txt.setText(position + 1);
you are close to your solution. You just have to typecast position + 1 to String since setText() only take String alone.
I have a listview which uses a CursorAdapter to populate the listview. I want to allow users to choose multiple items and perform actions, such as delete items, on all of the selected items at the same time. I tried adding a CheckBox item to the layout xml of the item item_vocab.xml. The checkbox showed up beside each item, but I wasn't able to figure out how to keep track of the status of the checked items. I also tried adding setChoiceMode(ListView.CHOICE_MODE_MULTIPLE) instead but the checkbox didn't show up.
Here are some of my code:

Please let me know if I need to provide further information.
You can use CustomListview for this, make another xml that have textview and checkbox and use that layout in your custom adapter class for populating list then it will work like you want. For example look this tutorial:
http://techlovejump.com/android-listview-with-checkbox/
I want to add an button to the footer of listview, I'm using horizontal listview, The adapter class:
public ItemAdapter(Context context, int layout, Cursor c,String[] from, int[] to) {
super(context, layout, c, from, to,0);
this.layout = layout;
inflator= LayoutInflater.from(context);
}
I return the newView and bindView:
public View newView(Context context, Cursor cursor, ViewGroup parent) {
View v = inflator.inflate(layout, parent, false);
TextView footer = (TextView)v.findViewById(R.id.bAdd);
return v;
}
#Override
public void bindView(View v, final Context context, Cursor c) {
final int id = c.getInt(c.getColumnIndex(ItemDb.ID));
final String name = c.getString(c.getColumnIndex(ItemDb.NAME));
}
and the activity class:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
String[] from = new String[] { ItemDb.NAME, ItemDb.CONDITION, ItemDb.EMAIL};
int[] to = new int[] { R.id.etItemName, R.id.etItemCondition, R.id.etEmail };
itemAdapter = new ItemAdapter(this,R.layout.list_item, null, from, to);
this.setListAdapter(itemAdapter);
}
How can I add the button in listview footer?
Here is my xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ImageView
android:id="#+id/photo"
android:layout_width="85dp"
android:layout_height="85dp"
android:background="#drawable/photo_frame"
android:contentDescription="#string/imagedescription"
android:src="#drawable/ic_launcher" >
</ImageView>
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<TextView
android:id="#+id/condition"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/name"
android:layout_marginLeft="10dp"
android:text="#string/condition"
android:textColor="#000"
android:textSize="14sp" />
<TextView
android:id="#+id/email"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/condition"
android:layout_marginLeft="10dp"
android:text="#string/email"
android:textColor="#000"
android:textSize="14sp" />
</RelativeLayout>
</LinearLayout>
Override getCount() of listview adapter to return data.size()+1 elements;
In getView() insert something like this:
if (position == data.size()){
return getFooterView();
}
In getFooterView() inflate proper layout with button.
