Android - Dynamically Adding TableRow to TableLayout using an existing TableRow layout

问题


I'm trying to adding TableRows to a TableLayout, which is working fantastically. However, I'm running into some problems with layout parameters. The spacing between the TextViews within a TableRow isn't working out like I thought it would.

My current code looks as follows.

paymentTable = (TableLayout) findViewById(R.id.paymentTable);

for(i = 0; i < cursor.getCount(); i++) {

        TableRow row = new TableRow(this);

        TextView payAmount = new TextView(this);
        payAmount.setText(cursor.getString(cursor.getColumnIndex(DatabaseHelper.KEY_AMOUNT)));
        payAmount.setPadding(payAmount.getPaddingLeft(), 
                             payAmount.getPaddingTop(), 
                             textView.getPaddingRight(), 
                             payAmount.getPaddingBottom());

        TextView payDate = new TextView(this);
        payDate.setText(cursor.getString(cursor.getColumnIndex(DatabaseHelper.KEY_DATE)));

        row.addView(payDate);
        row.addView(payAmount);

        paymentTable.addView(row, new TableLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));

        cursor.moveToNext();
    }

Afterwards, the TableLayout looks something along the lines of:

January$500

February$500

March$405

But I want it to look like:

January    $500
February   $500
March      $405

To clarify things, I want each new TableRow and the TextViews it contains to inherit layout properties of an existing TableRow and TextView(s).

yawus this is a good tutorial will help you set the table layout http://www.anotherandroidblog.com/2010/08/04/android-database-tutorial/

this is the xml layout

http://www.anotherandroidblog.com/2010/08/04/android-database-tutorial/6/

this is the activity code

http://www.anotherandroidblog.com/2010/08/04/android-database-tutorial/8/

TableRow tableRow= new TableRow(this);

            ArrayList<Object> row = data.get(position);

            TextView idText = new TextView(this);
            idText.setText(row.get(0).toString());
            tableRow.addView(idText);

            TextView textOne = new TextView(this);
            textOne.setText(row.get(1).toString());
            tableRow.addView(textOne);

            TextView textTwo = new TextView(this);
            textTwo.setText(row.get(2).toString());
            tableRow.addView(textTwo);

            dataTable.addView(tableRow);

You need to add a RelativeLayout to each Table

TableRow row = new TableRow(this);
                            row.setId(tag);
                         // Creating a new RelativeLayout

                            RelativeLayout relativeLayout = new RelativeLayout(this);
                            // as the parent of that RelativeLayout is a TableRow you must use TableRow.LayoutParams
                            TableRow.LayoutParams rlp = new TableRow.LayoutParams(
                                    TableRow.LayoutParams.MATCH_PARENT,
                                    TableRow.LayoutParams.MATCH_PARENT);   
                            rlp.setMargins(0, 0, 0, 0);
                            row.addView(relativeLayout, rlp);

Then you add your TextView to the RelativeLayout. Like this

RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
                          RelativeLayout.LayoutParams.WRAP_CONTENT,
                          RelativeLayout.LayoutParams.WRAP_CONTENT);
TextView payAmount = new TextView(this);
//lp.setMargins(left, top, right, bottom)
lp.setMargins(0, 0, 16, 0);
lp.addRule(RelativeLayout.ALIGN_LEFT);
payAmount.setLayoutParams(lp);
relativeLayout.addView(payAmount);

RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
                          RelativeLayout.LayoutParams.WRAP_CONTENT,
                          RelativeLayout.LayoutParams.WRAP_CONTENT);
TextView payDate = new TextView(this);
//lp.setMargins(left, top, right, bottom)
lp.setMargins(0, 0, 16, 0);
lp.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
payDate.setLayoutParams(lp);
relativeLayout.addView(payDate);

This is the way I handle positioning interface components within a table row.
