Android ListView with Sqlite access

I build a activity with a listview.
Populate it by use of sqlite.
But, when I write a few records into the DB and than show the result in the listView.
He doesn't show all the records.
Thank a lot for you help.
debug screen
D/DstNote: Find all arrow info.
D/DstNote: Records : 3
D/DstNote: 454554
D/DstNote: 45545454
D/DstNote: Find all arrow info.
D/DstNote: Records : 3
D/DstNote: position : 0
D/DstNote: position : 1
Méthode to read the data into DB
public ArrayList<ArrowInfo> getAllArrowInfo() {
Log.d("DstNote", "Find all arrow info.");
ArrayList<ArrowInfo> allArrowInfo = new ArrayList<>();
String[] selectedColomns = new String[] {
COLOMN_ID, COLOMN_ARROW_REF, COLOMN_TYPE_ARC, COLOMN_FIELD_IN, COLOMN_FIELD_OUT
};
Cursor c = db.query(TABLE_NAME, selectedColomns, null, null, null, null, null);
c.moveToFirst();
Log.d("DstNote", ""+c.getCount());
while (c.moveToNext()) {
Log.d("DstNote", cursorToArrow(c).getArrowRef());
allArrowInfo.add(cursorToArrow(c));
}
return allArrowInfo;
}
the adapter
class ArrowInfoAdapter extends BaseAdapter {
private Context ctx;
private ArrayList<ArrowInfo> allArrayInfo;
public ArrowInfoAdapter(Context context, ArrayList<ArrowInfo> allArrayInfo) {
ctx = context;
this.allArrayInfo = allArrayInfo;
}
#Override
public int getCount() {
return (allArrayInfo != null) ? allArrowInfo.size() : 0;
}
#Override
public long getItemId(int position) {
return position;
}
#Nullable
#Override
public ArrowInfo getItem(int position) {
return allArrowInfo.get(position);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ArrowInfo currentArrowInfo = allArrowInfo.get(position);
View itemView = convertView;
if (itemView == null) {
itemView = getLayoutInflater().inflate(R.layout.simple_listview_arraw_info_item, parent, false);
}
Log.d("DstNote", "position : " + position);
TextView refArrow = (TextView) itemView.findViewById(R.id.refArrow);
TextView arcType = (TextView) itemView.findViewById(R.id.arctype_TextView);
TextView field = (TextView) itemView.findViewById(R.id.field_textview);
refArrow.setText(currentArrowInfo.getArrowRef());
arcType.setText(currentArrowInfo.getTypeArc().name());
field.setText((currentArrowInfo.getIndoor() == 0) ? "IN" : "OUT");
itemView.setTag(currentArrowInfo);
return itemView;
}
public void refresh() {
/*allArrowInfo.clear();
allArrowInfo.addAll(model.getAllArrowInfo());*/
notifyDataSetChanged();
}
}
and the create méthod
allArrowInfo = model.getAllArrowInfo();
for (ArrowInfo item : allArrowInfo) {
Log.d("DstNote", item.getArrowRef());
}
adapter = new ArrowInfoAdapter(getBaseContext(), allArrowInfo);
registerForContextMenu(arrowInfoListView);
arrowInfoListView.setAdapter(adapter);

Trying to get the _id when an item in gridview is clicked getting a cast exception

I am trying to get the _id field from the cursor when an item in my Grid View is clicked, the same code is working fine in a listview but does not seem to work here:
Class level:
CurAdapter Cur;
GridView grid;
onCreate:
Cursor mCur = dbHelper.contactsQuery();
grid = (GridView)rootView.findViewById(R.id.gridview);
Cur = new CurAdapter(getActivity(), mCur,0);
grid.setAdapter(Cur);
grid.setTextFilterEnabled(true);
onCLick:
grid.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,int position, long id) {
System.out.println(position);
System.out.println(id);
Cursor cursor = (Cursor) grid.getItemAtPosition(position);
}
});
My CustomAdapter:
private class CurAdapter extends CursorAdapter{
public CurAdapter(Context context, Cursor c, int flags) {
super(context, c, flags);
}
#Override
public void bindView(View view, Context context, Cursor cursor) {
TextView tv = (TextView) view.findViewById(R.id.item_text);
tv.setTypeface(helv_light);
final RoundedImageView iv = (RoundedImageView) view.findViewById(R.id.item_image);
String name = (cursor.getString(cursor.getColumnIndexOrThrow("Name")));
image = cursor.getString(cursor.getColumnIndexOrThrow("imageUri"));
String isAdhoc = (cursor.getString(cursor.getColumnIndexOrThrow("isAdhoc")));
if(isAdhoc.equals("1")){
boolean check = false;
String frName = null;
Cursor mCur = dbHelper.friendsName(name);
if(mCur != null && mCur.moveToFirst()){
do{
frName = mCur.getString(mCur.getColumnIndex("FriendsName"));
if(frName != null){
if(frName.equalsIgnoreCase(selfName)){
check = false;
}else {
check = true;
}
}
}while (mCur.moveToNext());
}
if(check){
name = name+" "+"("+frName+"'s"+" pet)";
}
}
tv.setText(name);
if((image.contains("jpg") || image.contains("png")) && image.contains("adhoc") != true){
image = "file://"+image;
}
final DisplayImageOptions options = new DisplayImageOptions.Builder()
.showImageOnLoading(R.drawable.icon_default)
.showImageForEmptyUri(R.drawable.icon_default)
.showImageOnFail(R.drawable.icon_default)
.resetViewBeforeLoading(true)
.cacheInMemory(true) // default
.cacheOnDisk(true) // default
.build();
ImageLoader.getInstance().displayImage(image, iv, options);
}
#Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
View view = LayoutInflater.from(context).inflate(R.layout.grid_layout, null);
return view;
}
public long getItemId(int position) {
return position;
}
public Object getItem(int position) {
return position;
}
}
My Problem:
11-10 14:51:47.989: E/AndroidRuntime(11194): java.lang.ClassCastException: java.lang.Integer cannot be cast to android.database.Cursor
11-10 14:51:47.989: E/AndroidRuntime(11194): at com.example.FragmentTab3$1.onItemClick(FragmentTab3.java:125)

you are getting the ClassCastException because you are overriding getItem
public Object getItem(int position) {
return position;
}
and in your case it is returning an int not the cursor. You can delete it and use the parent implementation of getItem (which should return the Cursor at position)

Exception is due to return int from getItem(..) as mentioned by blackbelt
This may also help you to get ID of the record - change getItemId(..) this way:
public long getItemId(int position) {
mCur.moveToPosition(position);
return mCur.getLong(mCur.getColumnIndex(BaseColumns._ID));
}

Delete an item from Array List contact to Custom List View always delteing the latest one

I have a custom list view, contains delete button and spinner (the spinner contain A-E characters).
And I have an issue with deleting the true row from my custom list view.
Custom list view code:
public class customListView extends BaseAdapter
{
public Activity context;
ArrayList<MyActivity.UserProperties> userPropertieses;
public String[] spinnerValues;
public LayoutInflater inflater;
public customListView(Activity context, ArrayList<MyActivity.UserProperties> userPropertieses, String[] spinnerArray)
{
super();
this.context = context;
this.userPropertieses = userPropertieses;
spinnerValues = spinnerArray;
this.inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public int getCount() { return userPropertieses.size(); }
#Override
public Object getItem(int i) { return null; }
#Override
public long getItemId(int i) { return 0; }
class ViewHolder
{
Button btnRemove;
Spinner spinner;
}
#Override
public View getView(final int i, View view, ViewGroup viewGroup)
{
final ViewHolder holder;
if (view == null)
{
holder = new ViewHolder();
view = inflater.inflate(R.layout.custom_layout, null);
holder.spinner = (Spinner) view.findViewById(R.id.spinner);
holder.btnRemove = (Button) view.findViewById(R.id.bu_Remove);
// populate spinner
ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>
(view.getContext(), android.R.layout.simple_spinner_item, spinnerValues);
dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
holder.spinner.setFocusable(true);
holder.spinner.requestFocus();
holder.spinner.setAdapter(dataAdapter);
view.setTag(holder);
// remove user implementation
holder.btnRemove.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Log.i("custom list view debug", "i = " + i); // debug. verify i value is correct
((MyActivity) context).deleteUser(i);
}
});
}
else
holder = (ViewHolder) view.getTag();
return view;
}
}
And my main activity code looks like this:
public class MyActivity extends Activity
{
ListView listView;
ArrayList<UserProperties> userProperties = new ArrayList<UserProperties>();
customListView adapter;
SensorManager sensorManager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my);
sensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
for (int i = 0; i<5; i++) {
userProperties.add(new UserProperties());
}
listView = (ListView) findViewById(R.id.listView);
String[] spinnerValues = new String[] {"A", "B", "C", "D", "E"};
adapter = new customListView(MyActivity.this, userProperties, spinnerValues);
listView.setAdapter(adapter);
}
public void deleteUser (int index)
{
Log.i("debug", "Removing item " + index); // the index is really true and the true node deleting from the ArrayList but somehow the latest delete from the UI
userProperties.remove(index);
adapter.notifyDataSetChanged();
}
}
When I click on the Remove button deleteUser method called with the right index. but although the right node deleting from userProperties ArrayList somehow after notiftDataSetChanged is still alive
and the latest node delete.
So, How can I delete the right node/row (from the ArrayList and UI...)
Thank you!
EDIT:
Just to be clear, i variable contain true index. The true node deleted from the ArrayList. but something append after I called notify method.
I prefer to stay with BaseAdapter and not implement ArrayAdapter. Thank you!
EDIT 2:
After more debugging I found out my question was wrong. the true row really deleted just spinner values somehow update their values. I cannot close the question because it already answered. Thanks.

((MyActivity) context).deleteUser(i);
This line will always delete the first value from the ListView
You can use CAB (contextual action bar)
See if the code helps you(it's basically a ListActivity with a custom adapter to hold the status of checked items(+ different background)):
public class CABSelection extends ListActivity {
private ArrayList<String> mItems = new ArrayList<String>();
private SelectionAdapter mAdapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
for (int i = 0; i < 24; i++) {
mItems.add("Name" + i);
}
// R.layout.adapters_cabselection_row is a LinearLayout(with green
// background(#99cc00)) that wraps an ImageView and a TextView
mAdapter = new SelectionAdapter(this,
R.layout.adapters_cabselection_row, R.id.the_text, mItems);
setListAdapter(mAdapter);
getListView().setChoiceMode(ListView.CHOICE_MODE_MULTIPLE_MODAL);
getListView().setMultiChoiceModeListener(new MultiChoiceModeListener() {
private int nr = 0;
#Override
public boolean onCreateActionMode(ActionMode mode, Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.cabselection_menu, menu);
return true;
}
#Override
public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
return false;
}
#Override
public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
StringBuilder sb = new StringBuilder();
Set<Integer> positions = mAdapter.getCurrentCheckedPosition();
for (Integer pos : positions) {
sb.append(" " + pos + ",");
}
switch (item.getItemId()) {
case R.id.edit_entry:
Toast.makeText(CABSelection.this, "Edited entries: " + sb.toString(),
Toast.LENGTH_SHORT).show();
break;
case R.id.delete_entry:
Toast.makeText(CABSelection.this, "Deleted entries : " + sb.toString(),
Toast.LENGTH_SHORT).show();
break;
case R.id.finish_it:
nr = 0;
mAdapter.clearSelection();
Toast.makeText(CABSelection.this, "Finish the CAB!",
Toast.LENGTH_SHORT).show();
mode.finish();
}
return false;
}
#Override
public void onDestroyActionMode(ActionMode mode) {
nr = 0;
mAdapter.clearSelection();
}
#Override
public void onItemCheckedStateChanged(ActionMode mode,
int position, long id, boolean checked) {
if (checked) {
nr++;
mAdapter.setNewSelection(position, checked);
} else {
nr--;
mAdapter.removeSelection(position);
}
mode.setTitle(nr + " rows selected!");
}
});
}
#Override
protected void onListItemClick(ListView l, View v, int position, long id) {
l.setItemChecked(position, !mAdapter.isPositionChecked(position));
}
private class SelectionAdapter extends ArrayAdapter<String> {
private HashMap<Integer, Boolean> mSelection = new HashMap<Integer, Boolean>();
public SelectionAdapter(Context context, int resource,
int textViewResourceId, List<String> objects) {
super(context, resource, textViewResourceId, objects);
}
public void setNewSelection(int position, boolean value) {
mSelection.put(position, value);
notifyDataSetChanged();
}
public boolean isPositionChecked(int position) {
Boolean result = mSelection.get(position);
return result == null ? false : result;
}
public Set<Integer> getCurrentCheckedPosition() {
return mSelection.keySet();
}
public void removeSelection(int position) {
mSelection.remove(position);
notifyDataSetChanged();
}
public void clearSelection() {
mSelection = new HashMap<Integer, Boolean>();
notifyDataSetChanged();
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = super.getView(position, convertView, parent);//let the adapter handle setting up the row views
v.setBackgroundColor(Color.parseColor("#99cc00")); //default color
if (mSelection.get(position) != null) {
v.setBackgroundColor(Color.RED);// this is a selected position so make it red
}
return v;
}
}
}

Another way
adapter = new MyListAdapter(this);
lv = (ListView) findViewById(android.R.id.list);
lv.setAdapter(adapter);
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> a, View v, int position, long id) {
AlertDialog.Builder adb=new AlertDialog.Builder(MyActivity.this);
adb.setTitle("Delete?");
adb.setMessage("Are you sure you want to delete " + position);
final int positionToRemove = position;
adb.setNegativeButton("Cancel", null);
adb.setPositiveButton("Ok", new AlertDialog.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
MyDataObject.remove(positionToRemove);
adapter.notifyDataSetChanged();
}});
adb.show();
}
});

getView(final int i,
Do not make i final. You did that to use i in onClick(). But that is not possible. So remove the final. Add:
holder.btnRemove.setTag(i);
And in onClick:
int position = v.getTag();
..deleteUser(position);
Maybe you have to cast something somewhere..
Remark: You have to set the tag always. So do it just before return view;.
Please do not use an i for position.

Get custom itemsAdapter id using cursor android

I'm trying to pass the item clicked to another activity i.e from A to B using a custom itemsAdapter with sqlite.
How can I achieve the following?
1)Get the item clicked position using cursor
2)Pass the item clicked to another activity
I'm trying to do similar to this example but use my own custom adapter
I have dome the following so far.
Activity A:
public void onListItemClick(ListView parent, View view, int position, long id) {
Intent intent = new Intent(this,F32Activity.class);
Cursor cursor = (Cursor) itemsAdapter.getItem(position);
intent.putExtra("PROPERTY_ID", cursor.getInt(cursor.getColumnIndex("_id")));
startActivity(intent);
return;
}
Activity B:
propertyId = getIntent().getIntExtra("PROPERTY_ID", 0);
System.out.println(employeeId);
SQLiteDatabase db = (new Helper(this)).getWritableDatabase();
Cursor cursor = db
.rawQuery("SELECT * from my_table WHERE pro._id = ?",
new String[] { "" + propertyId });
Added the Adapter
private void getItemId(int position) {
// TODO Auto-generated method stub
}
private void getDataAndPopulate() {
// TODO Auto-generated method stub
image = new ArrayList<byte[]>();
bedrooms= new ArrayList<String>();
address= new ArrayList<String>();
propType= new ArrayList<String>();
Cursor cursor = getEvents(" gall,properties where properties._id = gall._id " );
while (cursor.moveToNext()) {
//String temp_id = cursor.getString(0);
byte[] temp_image = cursor.getBlob(2);
String temp_identifier = cursor.getString(1);
String temp_price = cursor.getString(3);
String temp_bedrooms = cursor.getString(4);
String temp_address = cursor.getString(5);
String temp_propType = cursor.getString(6);
image.add(temp_image);
//System.out.println(image);
bedrooms.add(temp_bedrooms);
address.add(temp_address);
propType.add(temp_propType);
}
String[] identifierArray = (String[]) bedrooms.toArray(new String[bedrooms
.size()]);
itemsAdapter = new ItemsAdapter(PropertyResult.this,
cursor, R.layout.activity_f9, identifierArray);
setListAdapter(itemsAdapter);
}
private class ItemsAdapter extends BaseAdapter {
String[] items;
public ItemsAdapter(Context context, Cursor cursor,int textViewResourceId,
String[] items) {
this.items = items;
}
public View getView(final int POSITION, View convertView,
ViewGroup parent) {
TextView desc;
TextView cap;
TextView ident;
TextView pric;
TextView bedroom;
TextView addres;
TextView propertytyp;
View view = convertView;
ImageView img;
if (view == null) {
LayoutInflater vi = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = vi.inflate(R.layout.activity_f9, null);
}
img = (ImageView) view.findViewById(R.id.image);
bedroom = (TextView) view.findViewById(R.id.bedrooms);
addres = (TextView) view.findViewById(R.id.address);
propertytyp = (TextView) view.findViewById(R.id.propertytype);
bedroom.setText("£"+bedrooms.get(POSITION));
addres.setText(address.get(POSITION));
propertytyp.setText(propType.get(POSITION));
img.setImageBitmap(BitmapFactory.decodeByteArray(
image.get(POSITION), 0, image.get(POSITION).length));
return view;
}
public int getCount() {
return items.length;
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
}
Please kindly give me a solution.

In the onListItemClick() you already have the row id from the cursor, is the 4th parameter, id(this only works for cursor adapters).
First of all also create and ArrayList that will hold long values(the row ids from the cursor):
ids = new ArrayList<Long>();
//...
while (cursor.moveToNext()) {
String temp_id = cursor.getString(0);// if 0 is your column containing the id(check it)
ids.add(temp_id);
//...
}
Then in your adapter override the method getItemId and return the long values from the ids ArrayList according to the position supplied:
public long getItemId(int position) {
return ids.get(position);
}
Then in your onListItemClick() simply use the id parameter:
public void onListItemClick(ListView parent, View view, int position, long id) {
Intent intent = new Intent(this,F32Activity.class);
intent.putExtra("PROPERTY_ID", id);
startActivity(intent);
}
Then in the receiving activity:
propertyId = getIntent().getLongExtra("PROPERTY_ID", 0);

Your on Item should like this
public void onItemClick(AdapterView<?> arg0, View arg1, int position,
long arg3) {
String strEventName, strEventDate;
int Id;
Cursor c = (Cursor) arg0.getAdapter().getItem(position);
intent.putExtra("PROPERTY_ID", cursor.getInt(cursor.getColumnIndex("_id")));
startActivity(intent);}

Changing the Adapter at runtime

I am using an adapter to display the result of a cursor on a separate screen in alphabetical order. The problem is I need to use an EditText field to filter the result.
When I do this with the filter adapter always gives error due to the index properties of each alphabetical letter which he must redo. So I thought I'd change the adapter to a simple, no alphabetical division only when the user makes the filter for the search field.
I leave the original adapter and the adapter without a filter to search I add the filter that will run another cursor. This exchange of Adapter at runtime given problem: when I change the X Adapter (without filterqueryprovider) for the Y-Adapter (with filterqueryprovider) works normal .. but when the reverse is true filterqueryprovider just running in the X Adapter and the result of the cursor does not appear. How to solve this problem?
See the code below the adapter and my Activity
