String[] NoteList ;





@Override
protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_notiz_oeffnungs_menue);

        NoteListBtn = new Button[fileList().length];
        NoteList = fileList();

    for (int i = 0;i<fileList().length;i++)
    {

        NoteListBtn[i].setText(NoteList[i]);
        NoteListBtn[i].setOnClickListener(this);

You will need to add buttons in layout after you create them:

setContentView(R.layout.activity_notiz_oeffnungs_menue);
LinearLayout l1 = (LinearLayout)findViewById(R.id.layout1);

...

for (int i = 0;i<fileList().length;i++)
{
    NoteListBtn[i] = new Button(this);
    NoteListBtn[i].setText(NoteList[i]);
    NoteListBtn[i].setOnClickListener(this);
    l1.addView(NoteListBtn[i]);
}

Hope this helps.
