Horizonal LinearLayouts in a Vertical LinearLayout

I want a few EditTexts with buttons on their right. Right now I just have the Edittexts filling the parent with the 0dp trick. If I add the button the height of the EditText will shrink with wrap_content. If I do match_parent one EditText fills the entire screen.

RelativeLayout doesn't work because you can't make it match the parent in the same way as LinearLayout.

I thought of getting the screen height and then setting the layout height to 1/7 that (since I have 7 EditTexts). Plausible?

<LinearLayout xmlns:android="http://ift.tt/nIICcg"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout xmlns:android="http://ift.tt/nIICcg"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal">
    <EditText android:id="@+id/box_0"
        android:layout_weight="1"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:hint="@string/edit_task"
        android:saveEnabled="true"
        android:inputType="textCapSentences"
        android:maxLength="32"
        android:padding="10dp"/>
    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/button_send"
        android:layout_gravity="end"/>
    <!--red-->
    </LinearLayout>
<EditText android:id="@+id/box_1"
    android:layout_weight="1"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:saveEnabled="true"
    android:inputType="textCapSentences"
    android:maxLength="32"
    android:padding="10dp"/>
<EditText android:id="@+id/box_2"
    android:layout_weight="1"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:saveEnabled="true"
    android:inputType="textCapSentences"
    android:maxLength="32"
    android:padding="10dp"/>
<EditText android:id="@+id/box_3"
    android:layout_weight="1"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:saveEnabled="true"
    android:inputType="textCapSentences"
    android:maxLength="32"
    android:padding="10dp"/>
<EditText android:id="@+id/box_4"
    android:layout_weight="1"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:saveEnabled="true"
    android:inputType="textCapSentences"
    android:maxLength="32"
    android:padding="10dp"/>
<EditText android:id="@+id/box_5"
    android:layout_weight="1"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:saveEnabled="true"
    android:inputType="textCapSentences"
    android:maxLength="32"
    android:padding="10dp"/>
<EditText android:id="@+id/box_6"
    android:layout_weight="1"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:saveEnabled="true"
    android:inputType="textCapSentences"
    android:maxLength="32"
    android:padding="10dp"/>
</LinearLayout>

I only did the double LinearLayout in the first EditText.

See how the second one is larger than the rest to compensate and the first is smaller?
