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>

The way you have added a row into the table layout you can add multiple TableRow instances into your tableLayout object

tl.addView(row1); tl.addView(row2); 

etc...
