ImageButton not Showing

Question

I'm trying to add an ImageButton at first, and here is the XML that contains it:

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:layout_alignParentTop="true"
    android:id="@+id/name_search_layout"
    android:background="@android:color/darker_gray"
   >

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/label_name"
        android:text="@string/name_label"
        android:textSize="20sp"
        android:layout_marginLeft="10dp"
        android:layout_marginRight="10dp"
        android:textStyle="bold" />


    <EditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/text_name"
        android:hint="@string/name_hint"
        android:layout_marginLeft="10dp"
        android:layout_marginRight="10dp"/>

    <ImageButton
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/button_expand"
        android:layout_gravity="right"
        android:src="@android:drawable/btn_plus"
        />
</LinearLayout>

This is inside another LinearLayout, but my button don't appear, it shows like this:

How can i make it appear?

Your imageButton not show, because, the width of EditText is match_parent, please change it to wrap_content like this

<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_alignParentTop="true"
android:id="@+id/name_search_layout"
android:background="@android:color/darker_gray">

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/label_name"
    android:text="@string/name_label"
    android:textSize="20sp"
    android:layout_marginLeft="10dp"
    android:layout_marginRight="10dp"
    android:textStyle="bold" />


<EditText
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/text_name"
    android:hint="@string/name_hint"
    android:layout_marginLeft="10dp"
    android:layout_marginRight="10dp"/>

<ImageButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/button_expand"
    android:layout_gravity="right"
    android:src="@android:drawable/btn_plus"
    />
