How can I create a list Array with the cursor data in Android

In Kotlin you can use this extension:

fun <T> Cursor.toList(block: (Cursor) -> T) : List<T> {
    return mutableListOf<T>().also { list ->
        if (moveToFirst()) {
            do {
                list.add(block.invoke(this))
            } while (moveToNext())
        }
    }
}

and use it:

val listOfIds = cursor.toList { 
    // create item from cursor. For example get id:
    it.getLong(it.getColumnIndex("_id"))
}
