Android SQLite filling column with ContentValues

i want to fill an Android SQLite database. For each column I have a separate ContentValue. After researching i saw, that the insert method just fills row for row. But the length of the dataset differs every time the app starts. That means i cannot say how many ContentValues i need. And if I initialize them in a loop I cannot get them outside of the loop.

Can somebody help me? Thank you! Jdajul
