This example demonstrates how to add table rows Dynamically in Android Layout.
Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.
Step 2 − Add the following code to res/layout/activity_main.xml.
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="https://schemas.android.com/apk/res/android" xmlns:tools="https://schemas.android.com/tools" xmlns:app="https://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" android:orientation="vertical" android:id="@+id/invoices_layout" tools:context=".MainActivity"> <ScrollView android:layout_width="match_parent" android:layout_height="match_parent" > <TableLayout android:id="@+id/tableInvoices" android:layout_width="match_parent" android:layout_height="match_parent" android:padding="0dp" android:stretchColumns="*"> </TableLayout> </ScrollView> </LinearLayout>
Step 3 − Add the following code to src/MainActivity.java
