Question

How can I make a Layout with Buttons in matrix like:

Button Button

Button Button

I want to have access to these Buttons by the loop (for example, for()), because I want to change the text of these Buttons dynamically.

I tried to make a TableLayout and TableRow, but nothing works.

You can use TableLayout.

Check here for explanation:

Here an example:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
    android:orientation="vertical" 
    android:layout_height="fill_parent" 
    android:layout_width="match_parent"
    android:id="@+id/mainLayout">

<TableLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:id="@+id/tableLayout1">
    <TableRow 
        android:id="@+id/tableRow2" 
        android:layout_width="match_parent" 
        android:layout_height="match_parent">
        <Button
             android:layout_height="wrap_content" 
             android:id="@+id/button1" 
             android:layout_width="wrap_content" 
             android:text="@string/first_color">
        </Button>
        <Button 
            android:id="@+id/button2" 
            android:layout_width="wrap_content" 
            android:layout_height="wrap_content"
            android:text="@string/second_color">
        </Button>
        <Button 
            android:id="@+id/button3" 
            android:layout_width="wrap_content" 
            android:text="@string/third_color" 
            android:layout_height="wrap_content">
        </Button>
    </TableRow>
    <TableRow 
        android:id="@+id/tableRow3" 
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content">
        <Button 
            android:id="@+id/button5" 
            android:layout_width="wrap_content" 
            android:layout_height="wrap_content" 
            android:text="@string/tolerance">
        </Button>
    </TableRow>
</TableLayout>
</LinearLayou>
