Question

Me and my partner have been working on a mobile app that focuses on scheduling and reserving rooms. We are having an issue with printing. As soon as we hit confirm for the information, it crashes and doesn't print to the table. Would love some help in figuring out our issue in this.

MainActivity.java

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        RoomAppDatabase.AppDatabase db = Room.databaseBuilder(getApplicationContext(),
                RoomAppDatabase.AppDatabase.class, "database-name").allowMainThreadQueries().build();
        RoomDao rao = db.roomDao();
        RoomUser dummy;
        //create default user list
        /*for(int i = 1; i < 9; i++)
        {

            //inserts user to database
            rao.insertRoomUser(user);

        }*/

        printTable();
        //setContentView(R.layout.activity_main);
    }

    public void printTable()
    {
        //loop to write names from database to the corresponding text entries on the main Activity
        for(int i=1;i<9;i++)
        {


            if(i == 1)
            {
                TextView txt =findViewById(R.id.rb1);
                txt.setText("Reserved by: "+user1.fullName);
            }
            if(i == 2)
            {
                TextView txt =findViewById(R.id.rb2);
                txt.setText("Reserved by: "+ user2.fullName);
            }
            if(i == 3)
            {
                TextView txt =findViewById(R.id.rb3);
                txt.setText("Reserved by: "+ user3.fullName);
            }

            }
            if(i == 5) {
                TextView txt = findViewById(R.id.rb5);
                txt.setText("Reserved by: " + user5.fullName);
            }
            if(i == 6)
            {
                TextView txt =findViewById(R.id.rb6);
                txt.setText("Reserved by: "+ user6.fullName);
            }

I am a beginner user for android studios and stack overflow, so i apologize if have made any noob mistakes!

Answer 1

You're using

dummy = Integer.parseInt((String)editText.toString());

toString of editText will return it's info which is a huge string use getText like below

dummy = Integer.parseInt((String)editText.getText().toString());
