I'm working on Android application and when trying to get SQLite database data as TextView (only one record in the table) facing this error.

Please help me for avoid this error.

Can you please highlight Line number 44 in TourInfo.java – Galegalea

Index 1 requested, with a size of 1 , it means that the size of that array is 1 so use 0 instead of calling with 1 – Sophist

Have written the query to create table first ? – Sterling

yes i created table and it had one tecord – Melissiamelita

@Galegalea line 44 is startLocationView.setText(cursorJObInfo.getString(1)); – Melissiamelita

Answer 1

You loop through your cursor in the do-while loop but access cursor data with getString() after it, when the cursor is pointing after the last result row.

It's a little unclear what you want to do: You're fetching all records but are only using one result row. As a quick fix, capture the values inside the do-while and not after, e.g.

String startLocation = null;
String endLocation = null;
String type = null;

if(cursorJObInfo.moveToFirst()){
    do{
        startLocation = cursorJObInfo.getString(1);
        endLocation = cursorJObInfo.getString(2);
        type = cursorJObInfo.getString(3);
        Log.d("DB value", startLocation +" "+ endLocation +" "+ type);
    }while(cursorJObInfo.moveToNext());
}

// ...
startLocationView.setText(startLocation); // instead of calling getString() on the cursor here
// the same for the other textviews

Answer 2

If you encounter a similar error in the future, this is the cause of the problem:

You are resetting the index before checking whether the cursor is empty because do..while executes at least once before checking if the condition is satisfied. to avoid this error, try while...do instead. You can even ignore the do part:

First check if the cursor is empty using Cursor.geCount

then move to the first record. Note: make sure you're not in the loop otherwise your will get into infinite loop.

then loop through the cursor using while..do

if(yourCursor.getCount()>0){
   yourCursor.moveToFirst();
   while(!yourCursor.isAfterLast()){
       startLocation = yourCursor.getString(1);
       endLocation = yourCursor.getString(2);
      yourCursor.moveToNext();
   }
}

Answer 3

Check whether there is data available in the table.

This Cursor cursorJObInfo = jobInfoDatabaseHelper.getAllJobInfoRecords(); is NULL because there is probably no data in the table.

table is created and it has one record – Melissiamelita
