Question

I’m new to Android. I’m trying to write a single method that would display 3 different columns from the same row of a database in 3 different textviews. Right now, I have 3 identical methods that each display a different column from the same row:

        Display part of Method #1:
if (cursor != null){
        cursor.moveToFirst();
        result = result
        + cursor.getString(0);
        return result;
    }
    return null;


    Display part of Method #2:
if (cursor != null){
        cursor.moveToFirst();
        result = result
        + cursor.getString(1);
        return result;
    }
    return null;

    Display part of Method #3:
if (cursor != null){
        cursor.moveToFirst();
        result = result
        + cursor.getString(2);
        return result;
    }
    return null;

So my question is: Is there a way to write a single method where the result would be something like “for a single DB row, cursor.getString(0); display in TextView #1, cursor.getString(1); display in TextView #2, cursor.getString(2); display in TextView #3?”

Answer 1

if (cursor != null){
    cursor.moveToFirst();
    String string1 = cursor.getString(0);
    .... string2 = cursor.getString(1);
    .... string3 = cursor.getString(2);
    textView1.setText(string1);
    textView2.setText(string2);
    textView3.setText(string3);
}

In case of Database Adapter, you can do one thing

if (cursor != null){
    cursor.moveToFirst();
    String strings[] = new String[3];
    strings[0] = cursor.getString(0);
    strings[1] = cursor.getString(1);
    strings[2] = cursor.getString(2);
    return strings;

In the calling activity you can set these returned array elements to textviews easily.

Hope this will help you.
