[android] How can I create a table with borders in Android?

To make 1dp collapse-border around every cell without writing a java code and without creating another xml layout with <shape...> tag, you can try this solution:

In <TableLayout...> add android:background="#CCC" and android:paddingTop="1dp" and android:stretchColumns="0"

In <TableRow...> add android:background="#CCC" and android:paddingBottom="1dp" and android:paddingRight="1dp"

In every cell/child in TableRow, i.e. <TextView...> add android:background="#FFF" and android:layout_marginLeft="1dp"

It is very important to follow paddings and margins as described. This solution will draw a 1dp border aka border-collapse property in (X)HTML/CSS.

Background color in <TableLayout...> and <TableRow...> represents a border line color and background in <TextView...> fills a table cell. You can put some padding in cells if necessary.

An example is here:

<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:background="#CCC"
    android:paddingTop="1dp"
    android:stretchColumns="0"
    android:id="@+id/tlTable01">

    <TableRow
        android:background="#CCC"
        android:paddingBottom="1dp"
        android:paddingRight="1dp">
        <TextView 
            android:layout_marginLeft="1dp"
            android:padding="5dp"
            android:background="#FFF"
            android:text="Item1"/>
        <TextView 
            android:layout_marginLeft="1dp"
            android:padding="5dp"
            android:background="#FFF"
            android:gravity="right"
            android:text="123456"/>
    </TableRow>
    <TableRow
        android:background="#CCC"
        android:paddingBottom="1dp"
        android:paddingRight="1dp">
        <TextView 
            android:layout_marginLeft="1dp"
            android:padding="5dp"
            android:background="#FFF"
            android:text="Item2"/>
        <TextView 
            android:layout_marginLeft="1dp"
            android:padding="5dp"
            android:background="#FFF"
            android:gravity="right"
            android:text="456789"/>
    </TableRow>
</TableLayout>
