Android Studio get data from sqlite

I had some problem about get data from sqlite different database.One database that save user's name and phone and they can update as they like. While another is house information but also contain user's name and phone.
My problem is i just realize that the phone that had been update in user database is not same with phone that previous store in house database. So i wanna call the user's phone from user database and use for phone call function and message function. But it does not work.And i trying to match the fullname that in user database with house database to call the phone data but still cant.
here is my call and message function
public class HouseDetail extends AppCompatActivity {
EditText etAddress,etDetail,etPhone;
TextView txType,txProperty,txPrice,txState,txTitle,txOther,txSize,txFullname;
ImageButton bPhone,bMessage;
String type,property,price,state,address,title,other,size,detail,fullnames,fullname,phone;
HousesDB db = new HousesDB(this);
Houses houses;
DatabaseOperations Udb = new DatabaseOperations(this);
PersonalData profileInfo;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_house_detail);
txType = (TextView) findViewById(R.id.txTypes);
txProperty = (TextView) findViewById(R.id.txProperty);
txPrice = (TextView) findViewById(R.id.txPrice);
txState = (TextView) findViewById(R.id.txState);
etAddress = (EditText) findViewById(R.id.etAddress);
txTitle = (TextView) findViewById(R.id.txTitle);
txOther = (TextView) findViewById(R.id.txOther);
txSize = (TextView) findViewById(R.id.txSize);
txFullname = (TextView) findViewById(R.id.txFullname);
etPhone = (EditText) findViewById(R.id.etPhone);
etDetail = (EditText) findViewById(R.id.etDetail);
bPhone = (ImageButton) findViewById(R.id.bPhone);
bMessage = (ImageButton) findViewById(R.id.bMessage);
fullnames = txFullname.getText().toString();
type = txType.getText().toString();
property = txProperty.getText().toString();
price = txPrice.getText().toString();
state = txState.getText().toString();
address = etAddress.getText().toString();
title = txTitle.getText().toString();
other = txOther.getText().toString();
size = txSize.getText().toString();
detail = etDetail.getText().toString();
phone = etPhone.getText().toString();
Intent i = getIntent();
property = i.getStringExtra("house_property");
txProperty.setText(property);
houses = db.getInfo(property);
txType.setText(houses.getTypes());
txFullname.setText(houses.getFullname());
txPrice.setText(houses.getPrice());
txState.setText(houses.getState());
etAddress.setText(houses.getAddress());
txTitle.setText(houses.getTitle());
txOther.setText(houses.getOther());
txSize.setText(houses.getSize());
etDetail.setText(houses.getDetail());
this.fullnames = fullname;
profileInfo = Udb.getNumber(fullname);
etPhone.setText(profileInfo.get_phone());
bPhone.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent callIntent =new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:" + etPhone));
startActivity(callIntent);
}
});
bMessage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("sms:" + etPhone)));
}
});
}
Here is my user database that get the phone number
public PersonalData getNumber(String fullname)
{
SQLiteDatabase SQ = this.getWritableDatabase();
String query = "select FullName,Phone from "+ Table_NAME;
Cursor CR = SQ.rawQuery(query,null);
String a;
PersonalData info = new PersonalData();
if (CR.moveToFirst())
{
do {
a = CR.getString(0);
if (a.equals(fullname)) {
info._phone = CR.getString(1);
break;
}
}while (CR.moveToNext());
}
return info;
}

try this:
public PersonalData getNumber(String fullName) {
SQLiteDatabase database = this.getReadableDatabase();
String table = "YOUR TABLE NAME";
String[] columns = {
"FullName" ,
"Phone"
};
Cursor cursor = database.query(table , columns , null , null , null , null , null);
cursor.moveToPosition(-1);
PersonalData info = new PersonalData();
while (cursor.moveToNext()) {
String name = cursor.getString(0);
if (name.equals(fullName)) {
info._phone = cursor.getString(1);
break;
}
}
cursor.close();
return info;
}

Replace
a = CR.getString(0);
if (a.equals(fullname)) {
info._phone = CR.getString(1);
break;
}
with
a = CR.getString(CR.getColumnIndex("Fullname"));
if (a.equals("FullName")) {
info._phone = CR.getString(CR.getColumnIndex("Phone"));
break;
}
your data gotten by query maybe not be ordered as you want,in your case that is, the result maybe not in "Fullname,Phone",so you should use getColumnIndex() to get data for each column.

The problem is in your SqlHandler.selectQuery() that returns a null, and another problem here checking the result:
if (c1 != null & c1.getCount() != 0)
You're using bitwise and & and not the short-circuiting logical and &&. Without short circuiting the complete expression including c1.getCount() on a null reference is evaluated.

There is too much here to explain it all, so I will give you the flaws causing a null pointer exception.
I can see your method of programming is coming from worrying too much about closing things and clearing up
resources to a point, it's causing problems.
contactList = new ArrayList<ContactListItems>();
// You are clearing your list, it should be empty, you have just created it.
contactList.clear();
String query = "SELECT * FROM PHONE_CONTACTS ";
Cursor c1 = SqlHandler.selectQuery(query);
// As mentioned by the other answer. You need && not &
// if (c1 != null & c1.getCount() != 0) {
if (c1 != null && c1.getCount() != 0) {
// Move to the first entry.
c1.moveToFirst();
//if (c1.moveToNext()) {
// do {
// Continue while it has not passed the last entry.
while (!cursor.isAfterLast())
contactListItems = new ContactListItems();
contactListItems.setSlno(c1.getString(c1.getColumnIndex("slno")));
contactListItems.setNameofevent(c1.getString(c1.getColumnIndex("nameofevent")));
contactListItems.setDtofevent(c1.getString(c1.getColumnIndex("dtofevent")));
contactListItems.setTimeofevent(c1.getString(c1.getColumnIndex("timeofevent")));
contactListItems.setDuration(c1.getString(c1.getColumnIndex("duration")));
contactList.add(contactListItems);
// Move the cursor along to the next entry.
cursor.moveToNext();
}
}
// Close cursor after while and within if (so you know it is not null).
c1.close();
}
else
{
// You can't close c1 if it is Null. This will throw and error. Lose the else.
c1.close();
}
// Move this to within your if statment.
c1.close();
From your code you provided in the chat.
Don't open and close your database continuously, just close each cursor you use when you're done. Just open it at the beginning and end of your program run.
public static Cursor selectQuery(String query) {
Cursor c1 = null;
try {
if (sqlDatabase.isOpen()) {
// You are closing the database.
sqlDatabase.close();
}
sqlDatabase = dbHelper.getWritableDatabase();
c1 = sqlDatabase.rawQuery(query, null);
} catch (Exception e) {
System.out.println("DATABASE ERROR " + e);
}
return c1;
}
There are many other flaws in your project. Like the structure and how and when you are calling things. You need to modularise it out, create methods for particular tasks and call those methods, rather than have a great lump of code in oncreate.
I am sure you will have many questions about this. But currently this question is addressing your null pointer exception and that is all I will discuss here. For questions about this not relating to this exception, please ask a new question. Hope this helps.

Android SQLite Database table - Created table.But error log says no such table

I am developing a shopping cart app.But got an error in adding item details to database, on
clicking ADD TO CART button. Error log says there is no such database table.and force me to SHUTTING DOWN VM. Please help me out.
I have two database in this activity.problem is with add2cart table in addcart database
Product_Detail.java
public class Product_Details extends Activity{
TextView name,price,specification,feature
String nme;
SQLiteDatabase mydb;
String pname;
String prprice;
String pspec;
String pfeature;
Button add2cart,by_nw;
ImageView image;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.product_dtls);
image=(ImageView)findViewById(R.id.pr_img);
name = (TextView) findViewById(R.id.txtPr_name);

add2cart=(Button)findViewById(R.id.add2cart);
by_nw=(Button)findViewById(R.id.buy_nw);
Intent in = getIntent();
Bundle bn = in.getExtras();
nme = bn.getString("key");
mydb=Product_Details.this.openOrCreateDatabase("addcart", MODE_PRIVATE, null);
mydb.execSQL("CREATE TABLE IF NOT EXISTS add2cart(img BLOB,pnme varchar,prate varchar,pqty varchar,ptotl vachar)");
mydb = Product_Details.this.openOrCreateDatabase("products", MODE_PRIVATE, null);
Cursor cr = mydb.rawQuery("SELECT * FROM product WHERE pname = '"+nme+"'", null);
while(cr.moveToNext())
{
String name = cr.getString(cr.getColumnIndex("pname"));
String pr1price = cr.getString(cr.getColumnIndex("pprice"));
String prspc=cr.getString(cr.getColumnIndex("pspec"));
String prfeature=cr.getString(cr.getColumnIndex("pfeature"));
pname = name;
prprice = pr1price;
pspec=prspc;
pfeature=prfeature;
}
name.setText(pname);
price.setText("Rs " +prprice + "/-");
specification.setText(pspec);
feature.setText(pfeature);
add2cart.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
String nm=name.getText().toString();
String rate=price.getText().toString();
mydb.execSQL("INSERT INTO add2cart VALUES('"+nm+"','"+rate+"')");

}
});
}
}

I opened my addcart database in setOnClickListner and my code worked.
Problem was the place where i opened the addcart database.It consider only the last opened database in Main.
Corrected code
public class Product_Details extends Activity{
TextView name,price,specification,feature;
String nme;
SQLiteDatabase mydb;
String pname;
String prprice;
String pspec;
String pfeature;
Button add2cart,by_nw;
ImageView image;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.product_dtls);
image=(ImageView)findViewById(R.id.pr_img);
name = (TextView) findViewById(R.id.txtPr_name);
price = (TextView) findViewById(R.id.txtprice);
specification=(TextView)findViewById(R.id.txtPr_spec);
feature=(TextView)findViewById(R.id.txtPr_feature);
add2cart=(Button)findViewById(R.id.add2cart);
by_nw=(Button)findViewById(R.id.buy_nw);
Intent in = getIntent();
Bundle bn = in.getExtras();
nme = bn.getString("key");
mydb = Product_Details.this.openOrCreateDatabase("products", MODE_PRIVATE, null);
Cursor cr = mydb.rawQuery("SELECT * FROM product WHERE pname = '"+nme+"'", null);
while(cr.moveToNext())
{
String name = cr.getString(cr.getColumnIndex("pname"));
String pr1price = cr.getString(cr.getColumnIndex("pprice"));
String prspc=cr.getString(cr.getColumnIndex("pspec"));
String prfeature=cr.getString(cr.getColumnIndex("pfeature"));
pname = name;
prprice = pr1price;
pspec=prspc;
pfeature=prfeature;
}
name.setText(pname);
price.setText("Rs " +prprice + "/-");
specification.setText(pspec);
feature.setText(pfeature);
add2cart.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
String nm=name.getText().toString();
String rate=price.getText().toString();
mydb=Product_Details.this.openOrCreateDatabase("addcart", MODE_PRIVATE, null);
mydb.execSQL("INSERT INTO add2cart (pnme,prate)VALUES('"+nm+"','"+rate+"')");
Toast.makeText(getApplicationContext(),"add to cart",Toast.LENGTH_SHORT).show();
Intent in=new Intent(Product_Details.this,add2cart.class);
startActivity(in);
}
});

You use this line mydb = Product_Details.this.openOrCreateDatabase("products", MODE_PRIVATE, null); to reset the mydb,now the mydb is the batabase products

Retrieving values from input texts android

I am trying to retrieve the values from the edit text input boxes and store them in a database. I am getting a null pointer exception and I am not sure why. Thanks in advance for the help :)
This is my code where I am retrieving the values and passing them as parameters to be stored in the database:
public class MyPage extends Activity {
final Context context = this;
public String stringName;
public int intAge;
public int intWeight;
public int intHeight;
public String stringGoal;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.my_page);
final Button button = (Button) findViewById(R.id.btn_addInfo);
button.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// custom dialog
final Dialog dialog = new Dialog(context);
dialog.setContentView(R.layout.dialogue_userinfo);
dialog.setTitle("Add Your Information");
Button dialogButton = (Button) dialog.findViewById(R.id.btnDone);
// if button is clicked, close the custom dialog
dialogButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
EditText textName = (EditText)findViewById(R.id.txtName);
stringName = textName.getText().toString();
EditText textAge = (EditText)findViewById(R.id.txtAge);
intAge = Integer.parseInt(textAge.getText().toString());
EditText textWeight = (EditText)findViewById(R.id.txtWeight);
intWeight = Integer.parseInt(textWeight.getText().toString());
EditText textHeight = (EditText)findViewById(R.id.txtHeight);
intHeight = Integer.parseInt(textHeight.getText().toString());
EditText textGoal = (EditText)findViewById(R.id.txtGoal);
stringGoal = textGoal.getText().toString();
DatabaseAccess();
dialog.dismiss();
}
});
dialog.show();
Window window = dialog.getWindow();
window.setLayout(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
}
});
}
private void DatabaseAccess(){
DatabaseHandler db = new DatabaseHandler(this);
/**
* CRUD Operations
* */
// Inserting User
Log.d("Insert: ", "Inserting ..");
db.addUser(new User(stringName, intAge, intWeight, intHeight, stringGoal));
//db.addUser(new User("Peter Parker", 23, 50, 150, "Hi"));
// Reading all users
Log.d("Reading: ", "Reading all contacts..");
List<User> users = db.getAllUsers();
for (User us : users) {
String log = "Id: "+us.getId()+" ,Name: " + us.getName() + " ,Age: " + us.getAge()
+ " ,Weight: " + us.getWeight() + " ,Height: " + us.getHeight()
+ " ,Goal: " + us.getGoal()
+ " ,BMI: " + us.getBmi();
Log.d("Name: ", log);
}
}
}

if All EditText's inside Dialog dialogue_userinfo layout then use Dialog instance for initializing EditText's instances on Button click. do it as:
EditText textName = (EditText)dialog.findViewById(R.id.txtName);
stringName = textName.getText().toString();
EditText textAge = (EditText)dialog.findViewById(R.id.txtAge);
intAge = Integer.parseInt(textAge.getText().toString());
//....same for others...

getText will return Editable Object. If your edittext has no any characters, it maybe return the null Object. So you have to check whether getText() return a null object.
if(youreditView.getText() != null ) {
String content = youreditView.getText().toString();
}

Intent data not displaying right

I'm having a issue where when I go to the next activity and pass then data with the intent it is only showing me the last entry off the DB and not the clicked items info.

Any Ideas?

You are iterating through your cursor and assigning the values to your strings. when it completes the iteration, your strings only contain the last value you assigned and then you pass that.
You should bind your list to a SimpleCursorAdapter instead of creating a whole different string array. Then in your onClickListener, you can just pass the key that identifies your row of data in the database.
