Open “res/layout/main.xml” file, add 3 “CheckBox” and a button, inside the LinearLayout, following is the sample code -

File : res/layout/main.xml

Markup

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <CheckBox
        android:id="@+id/chkIos"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/chk_ios" />

    <CheckBox
        android:id="@+id/chkAndroid"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/chk_android"
        android:checked="true" />

    <CheckBox
        android:id="@+id/chkWindows"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/chk_windows" />

    <Button
        android:id="@+id/btnDisplay"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/btn_display" />

</LinearLayout>

Some additional way of doing things...
There are basically two ways to create a control in android (or any platform)
- Thru editor or Layout XML
- Thru code / Runtime / Dynamic

For creating in Layout XML, @Ashish Kumer Khanna's answer should help you.

For creating in Runtime, you could code something like this...

Button button1 = new Button(this);
button1.setText("I am Button");

LinearLayout layout = (LinearLayout)findViewById(R.id.mylayout);
LayoutParams layoutParams = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
layout.addView(button1, layoutParams);

Hope this helps!
