I have a textview that gets data from sqlite database but when I delete a row,or change it ,I also want to change what the textview has,the data the textview contains is basically the sum of all rows specific column,so how can I update the textview when updating sqlite data?
here is my main code:

And here is my DatabaseHelper.java

}
public Cursor getDataOfTable(){

return data;
}
public String getPriceSum(){
SQLiteDatabase db = this.getWritableDatabase();
String query = "SELECT COALESCE(SUM(Price), 0) FROM " + TABLE_NAME;
Cursor price = db.rawQuery(query, null);

db.close();
return result;
}
public boolean ifExists()
{
SQLiteDatabase db = this.getWritableDatabase();
Cursor cursor = null;
String checkQuery = "SELECT * FROM " + TABLE_NAME + " LIMIT 1";
cursor= db.rawQuery(checkQuery,null);
boolean exists = (cursor.getCount() > 0);
cursor.close();
return exists;
}
public void delete(String nameofrow) {
SQLiteDatabase db = this.getWritableDatabase();
db.execSQL("delete from "+TABLE_NAME+" where "+NAME+"='"+nameofrow+"'");
}
}
Any help?!
The method getPriceSum() should return the sum and not a Cursor:
public String getPriceSum(){
SQLiteDatabase db = this.getWritableDatabase();
String query = "SELECT COALESCE(SUM(Price), 0) FROM " + TABLE_NAME;
Cursor c = db.rawQuery(query, null);
String result = "";
if (c.moveToFirst()) result = "" + c.getString(0);
c.close();
db.close();
return result;
}
I don't think that you need the if block:
if (mDatabaseHelper.ifExists()) {
.......................
}
All you need to do is:
total.setText(mDatabaseHelper.getPriceSum());
I have a listview with data using customAdapter.class now what i want is that to transfer checked items in listview to secondActivity on button click...
btest.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
SparseBooleanArray checked = listView.getCheckedItemPositions();
ArrayList<Model> mylist = new ArrayList<Model>();
for (int i = 0; i < checked.size(); i++) {
int position = checked.keyAt(i);
if (checked.valueAt(i))
// listView = new ArrayList<Model>();
mylist.add(String.valueOf(adapter.getItem(position)));
}
String[] output = new String[mylist.size()];
for (int i = 0; i < mylist.size(); i++) {
output[i] = (mylist.get(i));
}
Intent intent = new Intent(getApplicationContext(), ResultActivity.class);
Bundle b = new Bundle();
b.putStringArray("selectedItems", output);
// b.putStringArrayList("SelectedItems: ",list);
// b.putString("selectedItems", String.valueOf(output));
intent.putExtras(b);
startActivity(intent);*/
}
});
and this is the second activity where i am getting that data in another listview
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.result);
Bundle b = getIntent().getExtras();
String[] result = b.getStringArray("selectedItems");
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, result);
lv.setAdapter(adapter);
}
The method you followed to send custom list to another activity will not work. In order to transfer your custom list between activities you need to create Parcelable List and send it through intent.
Android Intents does not support custom list.
Custom list can be passed in two ways, Serialization and Parcelable.
But Parcelable is more Efficient and Simple to implement.
Refer this link to send custom list between activities through Parcelable
This link will give you much better idea to implement Parcelable.
Updated Code: Change your Model Code like below.
public class Model implements Parcelable{
private String name;
private int selected;
public Model(String name){
this.name = name;
selected = 0;
}
public String getName(){
return name;
}
public int isSelected(){
return selected;
}
public void setSelected(boolean selected){
this.selected = selected;
}
#Override
public int describeContents() {
// TODO Auto-generated method stub
return 0;
}
/**
* Storing the Student data to Parcel object
**/
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(name);
dest.writeInt(selected);
}
private Model (Parcel in){
this.name = in.readString();
this.selected = in.readInt();
}
public static final Parcelable.Creator<Model> CREATOR = new Parcelable.Creator<Model>() {
#Override
public Student createFromParcel(Parcel source) {
return new Student(source);
}
#Override
public Model[] newArray(int size) {
return new Model[size];
}
};
}
Then in the MainActivity do this..
Intent next = new Intent(MainActivity , ResultActivity.class);
next.putParcelableArrayListExtra("model_data", (ArrayList<? extends Parcelable>) selectedItems);
startActivity(next);
In the ResultActivity do this.
ArrayList<Model> his = getIntent().getParcelableArrayListExtra("model_data");
Try the above code..
Good Luck..!!
i solve by saving checked items from listview to sqlite on button click. another button to open new activity and call selected items sqlite this way...
oncheckchange add and remove items in an arraylist and call this in onbutton click like this way...
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder view = null;
Support support = (Support) this.getItem(position);
if (convertView == null){
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.view_items, null);
view = new ViewHolder();
view.tvInfo = (TextView) convertView.findViewById(R.id.tvInfo);
view.cb = (CheckBox) convertView.findViewById(R.id.cb);
convertView.setTag(view);
view.cb.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
CheckBox cb = (CheckBox) buttonView;
Support support = (Support) cb.getTag();
support.setSelected(cb.isChecked());
if (isChecked){
selList.add(support.status);
selID.add(support.id);
selType.add(support.type);
// Toast.makeText(CustomAdapter.this, "Clicked on Checkbox: " + cb.getText() + " is " + cb.isChecked(), Toast.LENGTH_LONG).show();
}else {
selList.remove(support.status);
selID.remove(support.id);
selType.remove(support.type);
}
}
});
}else{
view = (ViewHolder) convertView.getTag();
view.cb = view.getCb();
view.tvInfo = view.getTvInfo();
}
view.cb.setTag(support);
support = list.get(position);
String id = support.getId();
String status = support.getStatus();
String type = support.getType();
view.cb.setChecked(support.isSelected());
// view.tvInfo.setText(id + "," + status + "," + type);
view.tvInfo.setText(status);
return convertView;
}
this is button coding to add to db
btest.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
handler.addSelected(adapter.selList, adapter.selID, adapter.selType);
and this is how to insert to sqlite..
public void addSelected(ArrayList<String> selList, ArrayList<String> selID, ArrayList<String> selType) {
int size = selID.size();
SQLiteDatabase db = getWritableDatabase();
try{
for (int i = 0; i < size ; i++){
ContentValues cv = new ContentValues();
// cv.put(KEY_ID, selID.get(i).toString());
cv.put(KEY_ID, selID.get(i));
cv.put(KEY_STATUS, selList.get(i));
cv.put(KEY_TYPE, selType.get(i));
Log.d("Added ",""+ cv);
db.insertOrThrow(TABLE_SELECTED, null, cv);
}
db.close();
}catch (Exception e){
Log.e("Problem", e + " ");
}
}
and get back from db like this
public ArrayList<String> getSelected() {
SQLiteDatabase db = this.getReadableDatabase();
ArrayList<String> result = null;
try{
result = new ArrayList<String>();
// String query = "SELECT * FROM " + TABLE_SELECTED;
String query = "SELECT " + KEY_ID + " FROM " + TABLE_SELECTED;
Cursor c = db.rawQuery(query, null);
if (!c.isLast()){
if (c.moveToFirst()){
do{
String sel_name = c.getString(c.getColumnIndex("_id"));
result.add(sel_name);
Log.d("Added ", sel_name);
}while (c.moveToNext());
}
}
c.close();
db.close();
}catch (Exception e){
Log.e("Nothing is to show", e + " ");
}
return result;
}

Please help me .
Thank you
Are you sure the "context" you are using here is not null ?
How about rewriting the open() function this way and calling it via open(getApplicationContext()); ?
public DatabaseOperations open(Context context) throws SQLException {
ourHelper = new DatabaseOperations(context);
ourDatabase = ourHelper.getWritableDatabase();
return this;
}
In my Android application, I have a List of Phone Contacts. I want to add these contacts in private list by selection through CheckBoxe and onButtonClick. What I want here is that if contacts are already present there in database then they should not be added. How can i do so ? Please help.
Here is the code :
private MyListAdapter adapter;

lvTareas.setOnItemLongClickListener(new OnItemLongClickListener() {
#Override
public boolean onItemLongClick(AdapterView<?> arg0, View arg1,
int pos, long id) {
Log.d(Tag,"pos"+" "+pos);
return true;
}
});
But it not work. Help me please? what I do not correctly?
It happens due to focusability of CheckBox in my_list_item layout.
Add below line to root layout of your ListView's Item layout(my_list_item).
android:descendantFocusability="blocksDescendants"
