android - How to add rows dynamically into table layout

Question

I have certain data in sqllite and it update every time whenever, I click on save button and I want to show the data into a table layout for adding more rows for updated data.

I have certain code but it shows only the updated data replacing previous data and I want to add more rows as the data updated.

I know this is only to add one row into table layout but how can I add more rows?

TableLayout tl=(TableLayout)findViewById(R.id.maintable);    
TableRow tr1 = new TableRow(this);
tr1.setLayoutParams(new LayoutParams( LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT));
TextView textview = new TextView(this);
textview.setText(data);
//textview.getTextColors(R.color.)
textview.setTextColor(Color.YELLOW);
tr1.addView(textview);
tl.addView(tr1, new TableLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));

Here's technique I figured out after a bit of trial and error that allows you to preserve your XML styles and avoid the issues of using a <merge/> (i.e. inflate() requires a merge to attach to root, and returns the root node). No runtime new TableRow()s or new TextView()s required.

Code

Note: Here CheckBalanceActivity is some sample Activity class

TableLayout table = (TableLayout)CheckBalanceActivity.this.findViewById(R.id.attrib_table);
for(ResourceBalance b : xmlDoc.balance_info)
{
    // Inflate your row "template" and fill out the fields.
    TableRow row = (TableRow)LayoutInflater.from(CheckBalanceActivity.this).inflate(R.layout.attrib_row, null);
    ((TextView)row.findViewById(R.id.attrib_name)).setText(b.NAME);
    ((TextView)row.findViewById(R.id.attrib_value)).setText(b.VALUE);
    table.addView(row);
}
table.requestLayout();     // Not sure if this is needed.

attrib_row.xml

<?xml version="1.0" encoding="utf-8"?>
<TableRow style="@style/PlanAttribute"  xmlns:android="http://schemas.android.com/apk/res/android">
    <TextView
        style="@style/PlanAttributeText"
        android:id="@+id/attrib_name"
        android:textStyle="bold"/>
    <TextView
        style="@style/PlanAttributeText"
        android:id="@+id/attrib_value"
        android:gravity="right"
        android:textStyle="normal"/>
</TableRow>
