Updating a certain value and saving it in offline database

I'm developing a tiny app that has a value in a textview set to 150,000 by default. Each month I reset the value back to the default. Every time I spend some of that amount, I open my app and enter the amount I spent and the details of what it was spent on.
What I did was create an offline database to store all the times I spent some of that amount, along with it's id and details. Each time I press the "spend" button, the total amount is reduced by the amount I have entered in the EditText.
I haven't implemented how I'll update the total amount yet, I believe I have to use something called sharedpreference number.
This is the main activity:
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button spendMoney = (Button)this.findViewById(R.id.spendMoney);
Button test = (Button)this.findViewById(R.id.test);
TextView totalTxt = (TextView) this.findViewById(R.id.totalTxt);
final EditText spendAmount = (EditText)this.findViewById(R.id.spendAmount);
// int totalAmount = Integer.parseInt(totalTxt.getText().toString());
final Paid_DB db = new Paid_DB(this);
spendMoney.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
db.addPayment(new Payment(0, (Integer.parseInt(spendAmount.getText().toString())), "Test Details"));
}
});
//totalAmount = totalAmount - Integer.parseInt(spendAmount.getText().toString());
// totalTxt.setText(totalAmount);
test.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i = new Intent(null, DetailsActivity.class);
startActivity(i);
}
});

This is the object I enter into the offline database, containing the id, the amount spent, and details of the payment:
public class Payment {
private int id;
private int amount;
private String details;
public Payment(){}
public Payment(int id, int amount, String details) {
this.id = id;
this.amount = amount;
this.details = details;
}
public Payment(int id, int amount) {
this.id = id;
this.amount = amount;
}
public Payment(int amount, String details) {
this.amount = amount;
this.details = details;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public int getAmount() {
return amount;
}
public void setAmount(int amount) {
this.amount = amount;
}
public String getDetails() {
return details;
}
public void setDetails(String details) {
this.details = details;
} }
This is the offline database:
ublic class Paid_DB extends SQLiteOpenHelper {
// All Static variables
// Database Version
private static final int DATABASE_VERSION = 1;
// Database Name
private static final String DATABASE_NAME = "Payments_DB";
// Contacts table name
private static final String PAYMENT_TABLE = "PaymentTable";
// Contacts Table Columns names
private static final String PAY_ID = "id";
private static final String PAY_AMOUNT = "amount";
private static final String PAY_DETAILS = "details";
Paid_DB(Context context) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);
}
#Override
public void onCreate(SQLiteDatabase db) {
String CREATE_CONTACTS_TABLE = "CREATE TABLE " + PAYMENT_TABLE + "("
+ PAY_ID + " INTEGER PRIMARY KEY," + PAY_AMOUNT + " INTEGER,"
+ PAY_DETAILS + " TEXT" + ")";
db.execSQL(CREATE_CONTACTS_TABLE);
}
#Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
db.execSQL("DROP TABLE IF EXISTS " + PAYMENT_TABLE);
onCreate(db);
}
public void addPayment(Payment payment){
SQLiteDatabase db = this.getWritableDatabase();
ContentValues values = new ContentValues();
values.put(PAY_AMOUNT, payment.getAmount());
values.put(PAY_DETAILS, payment.getDetails()); // Contact Phone Number
// Inserting Row
db.insert(PAYMENT_TABLE, null, values);
db.close();
}
void addListItem(ArrayList<String> listItem) {
SQLiteDatabase db = this.getWritableDatabase();
ContentValues values = new ContentValues();
for (int i = 0; i < listItem.size(); i++) {
Log.e("vlaue inserting==", "" + listItem.get(i));
values.put(PAY_AMOUNT, listItem.get(i));
db.insert(PAYMENT_TABLE, null, values);
}
db.close(); // Closing database connection
}
Cursor getListItem() {
String selectQuery = "SELECT * FROM " + PAYMENT_TABLE;
SQLiteDatabase db = this.getWritableDatabase();
Cursor cursor = db.rawQuery(selectQuery, null);
return cursor;
}}
And finally, this is the details activity, it contains a list view that stores and displays all the payments that have been made:
public class DetailsActivity extends AppCompatActivity {
ArrayList<String> detailsListArrayList;
private ListView lv;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_details);
lv = (ListView) findViewById(R.id.listView);
detailsListArrayList = new ArrayList<>();
detailsListArrayList.add("Item1");
detailsListArrayList.add("Item2");
detailsListArrayList.add("Item3");
detailsListArrayList.add("Item4");
detailsListArrayList.add("Item5");
Paid_DB db = new Paid_DB(this);
db.addListItem(detailsListArrayList);
Cursor cursor = db.getListItem();
Log.e("count", " " + cursor.getCount());
if (cursor != null) {
cursor.moveToNext();
do {
Log.e("value==", "" + cursor.getString(1));
} while (cursor.moveToNext());
}
ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(
this,
android.R.layout.simple_list_item_1,
detailsListArrayList );
lv.setAdapter(arrayAdapter);
}
}

Every time I click on the "test" button, the app crashes. And every time I try to add a new entry using the "spend" button, the app also crashes. What did I do wrong?

What I can tell from here (without the error log) is:
1) your app crashes when pressing the test-button because you are starting an activity there without passing a contextobject. Try this:
public void onClick(View v) {
Intent i = new Intent(getApplicationContext(), DetailsActivity.class);
startActivity(i);
}
2) The spend button tries to add a new payment entry to your database. But in your database schema , you declare the PAY_ID as a primary key. Later in your addPayment() you are just passing the PAY_AMOUNT and PAY_DETAILS, so you are missing the PAY_ID which seems to lead to a crash.
EDIT: something like this should return all the payments as an ArrayList (may Contain bugs, just wrote it in this editor).
public ArrayList<Payment> getAllPayments() {
ArrayList<Payment> result = new ArrayList<>();
Cursor c = db.query("PAYMENTS",new String[]{"PAY_ID","PAY_AMOUNT","PAY_DETAIL"},null,null,null,null,null); ;
c.moveToFirst();
while(! c.isAfterLast())
{
int s1=c.getInt(0);
int s2=c.getInt(1);
String s3=c.getString(2);
results.add(new Payment(s1,s2,s3));
c.moveToNext();
}
return results;
}

After deletion instead of adapter.notifyDataSetChanged(); you can use the following code. It works fine for me:
adapter.remove(selectedName);

Android - Change SQLite value based on ToggleButton Image

I want to make an quote app which display the quote, the author, and a fav button.
I have a custom ListView which has 2 textViews, and 1 Toggle Button
I'm using SQLite with pre-populated data (So i already have all of the data)
I can populate my 2 textViews with my quote (from quote table) and author (from author table) using SimpleCursorAdapter
The Problem is, i have 1 ToggleButton which has:
Grey Heart image when its not selected (value 0)
Red Heart image when its selected (value 1)
What i want is
When the user click on the grey heart image (fav button), the image change to the red heart image and also updates the fav table in SQLite from 0 to 1.
When the user click on the red heart image (fav button), the image change to the grey heart image and also updates the fav table in SQLite from 1 to 0.
And when the user exit, and goes to my application again. i want the quotes that the user has already favorited before (value 1) still have red heart image.

When I insert a number it saves just the number 3. I don't know where is the problem.

You are getting the "length" of the number, not the value on these lines:
amount.getText().length()
I suspect you should be doing something like:
Integer.valueOf(amount.getText())
