android.database.CursorIndexOutOfBoundsException: Index 1 requested, with a size of 1

// This is not working. It shows first record and stops after that. I want a loop that keep running even after the last record. I got your point that cursor starts form position 0.
//Code

cur=db.getData(position);

    switch(v.getId())
    {

    case R.id.next :
    { 

        if (cur != null && cur.getCount()> 0 && position < cur.getCount() && position != cur.getCount()){
            cur.moveToPosition(position);
            textView1.setText(""+cur.getString(1));// Display Columns 
            position++;
            cur.moveToNext();
        }
}

// I want a loop to display record number

for next button eg:

1 2 3 4 5 1 2 3 4 5 1 2 3 4 5

back button eg:

5 4 3 2 1 5 4 3 2 1

random button eg:

3 4 5 1
5 1 2 3
4 5 1 2

Call get data before increments position, that because you are trying to acceed an element in a unexisting I'm your db. 

cur =db. getData(position) ;

Then 

position++;

Remember to first of all declare position = 0

That exception appears, because you are trying to get the object in a position that do not exist. Remember index start at 0.

Direct from DOCS :

 public abstract boolean moveToPosition (int position)

Added in API level 1

Move the cursor to an absolute position. The valid range of values is -1 <= position <= count.

This method will return true if the request destination was reachable, otherwise, it returns false. Parameters position the zero-based position to move to. Returns

whether the requested move fully succeeded.

if (cur != null && cur.getCount()> 0 && position < cur.getCount() && position != cur.getCount()){
                        cur.moveToPosition(position);
                        textView1.setText(""+cur.getString(1));// Display Columns 
                    }
