Question

when i try to click some name from listview, i want it to return the ID from its name(in Toast Text), but i always getting result "0" wherever i click a name in listview, can you help me fix my code?, thanks

MainActivity.java

public void toastMessage(String message) {
    Toast.makeText(this, message, Toast.LENGTH_SHORT).show();
}

public void toastMessageInt(int message) {
    Toast.makeText(this, message, Toast.LENGTH_SHORT).show();
}

public void refreshPage() {
    listView = findViewById(R.id.listView);
    ArrayList<String> arrayList = new ArrayList<>();
    Cursor getView = myDB.showListView();

    while (getView.moveToNext()) {
        arrayList.add(getView.getString(1));
        ListAdapter listAdapter = new ArrayAdapter<>(this, android.R.layout.simple_list_item_1,arrayList);
        listView.setAdapter(listAdapter);
    }

    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            String name = parent.getItemAtPosition(position).toString();
            int data = myDB.GetId(name);

DatabaseHelper.java

public void onCreate(SQLiteDatabase db) {
    db.execSQL("create table notepadData(id integer primary key autoincrement, notepad text)");
}

@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
    db.execSQL("drop table if exists notepadData");
    onCreate(db);
}

public int GetId(String currentNote) {
    SQLiteDatabase myDB = this.getWritableDatabase();
    Cursor getNoteId = myDB.rawQuery("select id from notepadData where notepad = '"+currentNote+"'",null);
    return getNoteId.getColumnIndex("id");
}

Try this:

Cursor getNoteId = myDB.rawQuery("select id from notepadData where notepad like + "'" + currentNote + "'", null);

Edit:
Wait...now I've noticed what you return...
getColumnIndex() returns you index of certain column, where your id column is always 0 and it won't change. You create table with two columns: id (index 0) and notepad (index 1)
You should use cursor.getInt(0) and before that call cursor.moveToFirst()
Do it like this:

    if (getNoteId != null && getNoteId.moveToFirst() {
       return getNoteId.getInt(0)
    } else {
       return null;  // because you have to return something
    }
