 int index =0;

for(String element: listOfSBPData){
        date1 = (String) element.subSequence(0,2);
        date2 = (String) tvDateFrom.getText().subSequence(0,2);
        if(element.contains(tvDateFrom.getText())){
            for(int i = 0; i<7; i++)
            if(date1.contains(date2)){
                listOfSBPDataToPlot.add(element);
                listOfSBPToPlot.add(listOfSBP.get(index));
            }
        }   
        index++;
}
