ScrollView Programmatically

Question

I picked up Java earlier in the week, and I am currently at the last step of creating an app. I am trying to print data in a table created programmatically. The issue is, I can't seem to figure out how to add scrollview to this table. The table goes on for hungreds of rows, so I need scrollview in order to view it correctly. Everything I have tried crashes my app. The following is my create table function.

private void createTable ()
 { 
   DecimalFormat format = new DecimalFormat ("##.00");

   LinearLayout.LayoutParams linearContainerParams = 
    new LinearLayout.LayoutParams ( 
    ViewGroup.LayoutParams.MATCH_PARENT, 
    ViewGroup.LayoutParams.WRAP_CONTENT, 
    0.0f); 

    LinearLayout.LayoutParams linearWidgetParams = new LinearLayout.LayoutParams (
        ViewGroup.LayoutParams.MATCH_PARENT, 
        ViewGroup.LayoutParams.MATCH_PARENT, 
        1.0f); 

        TableLayout.LayoutParams tableContainerParams = 
        new TableLayout.LayoutParams ( 
        ViewGroup.LayoutParams.MATCH_PARENT, 
        ViewGroup.LayoutParams.WRAP_CONTENT, 
        0.0f); 

        TableLayout.LayoutParams tableWidgetParams = 
        new TableLayout.LayoutParams ( 
        ViewGroup.LayoutParams.MATCH_PARENT, 
        ViewGroup.LayoutParams.MATCH_PARENT, 
        1.0f); 

        TableRow.LayoutParams rowContainerParams = 
        new TableRow.LayoutParams ( 
        ViewGroup.LayoutParams.MATCH_PARENT, 
        ViewGroup.LayoutParams.WRAP_CONTENT, 
        0.0f); 

        TableRow.LayoutParams rowWidgetParams = 
        new TableRow.LayoutParams ( 
        ViewGroup.LayoutParams.MATCH_PARENT, 
        ViewGroup.LayoutParams.MATCH_PARENT, 
        1.0f); 

        mRoot = new LinearLayout (this); 
        mRoot.setOrientation (LinearLayout.VERTICAL); 
        mRoot.setBackgroundColor (Color.LTGRAY); 
        mRoot.setLayoutParams (linearContainerParams); 

        mTableLayout = new TableLayout (this); 
        mTableLayout.setOrientation (TableLayout.VERTICAL); 
        mTableLayout.setBackgroundColor (Color.BLUE); 
        mTableLayout.setLayoutParams (tableContainerParams); 
        mRoot.addView (mTableLayout); 

        mTableRow = new TableRow (this); 
        mTableRow.setOrientation (TableLayout.VERTICAL); 
        mTableRow.setBackgroundColor (Color.CYAN); 
        mTableRow.setLayoutParams (rowContainerParams); 
        mTableLayout.addView (mTableRow); 

        mTextView = new TextView (this); 
        mTextView.setText ("Total"); 
        mTextView.setTextColor (Color.RED); 
        mTextView.setGravity (Gravity.RIGHT); 
        mTextView.setLayoutParams (rowWidgetParams); 
        mTableRow.addView (mTextView); 

        mTextView = new TextView (this); 
        mTextView.setText ("Month");

        mTextView.setTextColor (Color.RED); 
        mTextView.setGravity (Gravity.RIGHT); 
        mTextView.setLayoutParams (rowWidgetParams); 
        mTableRow.addView (mTextView); 

        int i = 0;

        for (i = 0; i < mTotalPaymentCount; ++i)
        {
          TextView text = new TextView (this);
          text.setText ("" + (i + 1));
          row.addView (text);

          text.setTextColor (Color.RED); 
          text.setGravity (Gravity.RIGHT); 
          text.setLayoutParams (rowWidgetParams);

          mTableLayout.addView (row);
        }


        setContentView (mRoot);
}

Is there any possible way for me to get scrollview working at all? Thank you to any help.

I think @FD_'s answer is right, however, if you still want to do it the way you proposed, the right way to do it is creating a ScrollView object and then adding the TableLayout via its addView() method.

ScrollView sv = new ScrollView(this);
sv.addView(yourTableLayout);
