Placing items below other items in Framelayout with Linearlayout

Question

I created an android xml file for some of my screens, and apparently I am using the navigation box in my application, so I am using the frame layout. Now I have added a linear layout that will show the following:

Text view with submit button

2 image buttons

This is a sample layout of what I want:

The problem is when I made my layout, I cannot hide the two buttons to make them lower than submit, and because what happens is that both buttons are on the right side of the layout, for example

This is my xml code:

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="mypackage.test.HomeActivity" >

    <FrameLayout
        android:id="@+id/container"
        android:layout_width="match_parent"
        android:layout_height="match_parent" >

        <LinearLayout 
            android:id="@+id/linerlayout"
            android:layout_width="match_parent"
            android:layout_height="100dp"
              android:gravity="center_horizontal"

            >
                    <EditText
            android:id="@+id/editText1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:ems="10"
            android:hint="Enter ID"
            >

            <requestFocus />
        </EditText>

            <Button
                android:id="@+id/button1"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="Submit" /> 
         <!--
        I'm trying to put the two buttons here but what happens is they both disappear when I put them

        -->      

        <Button
            android:id="@+id/button2"
            android:text="Button"
 android:layout_width="wrap_content"
                android:layout_height="wrap_content" />

        <Button
            android:id="@+id/button3"
            android:text="Button" 
 android:layout_width="wrap_content"
                android:layout_height="wrap_content"/>          
        </LinearLayout>

        </FrameLayout>

    <fragment
        android:id="@+id/navigation_drawer"
        android:name="mypackage.test.NavigationDrawerFragment"
        android:layout_width="@dimen/navigation_drawer_width"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        tools:layout="@layout/fragment_navigation_drawer" />
</android.support.v4.widget.DrawerLayout>

How can I pull both buttons down? Should I transfer buttons to another layout?
