layout_weight=1.0 doesn't have effect

Question

<LinearLayout android:orientation="horizontal"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <TextView
        android:id="@+id/tv_label_client_host"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:ems="10"
        android:text="@string/label_host" />
    <EditText
        android:id="@+id/et_client_host"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:ems="10" 
        android:inputType="text"
        android:layout_weight="1.0"
        android:lines="1" />
</LinearLayout>

I expect EditText to fill the whole space remaining by horizontal, but TextView and EditText get 1/2 of available space. This LinearLayout is placed inside of another vertical LinearLayout.

Answer 1

remove the

   android:ems="10"

for all the elements, I tested here and it works.
