Question

I’ve got a Button next to EditText control wrapped in LinearLayout. Everything seems to be fine except that the Button is significantly higher than the EditText and I’d like it to be the same height. The heights of @drawable/main_edittext and @drawable/main_edittext_button are the same, but even without background set, heights are different. In the application manifest file, application theme is set only to windowNoTitle=true.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:background="@drawable/main_background"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <EditText
        android:id="@+id/edit_message"
        style="@style/MainEditText"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:hint="@string/edit_message"
        android:singleLine="true" />

    <Button
        android:id="@+id/edit_message_button"
        style="@style/MainSearchButton"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:onClick="sendMessage"
        android:text="@string/button_send" />

</LinearLayout>

<style name="MainEditText">
    <item name="android:background">@drawable/main_edittext</item>
    <item name="android:textSize">16sp</item>
    <item name="android:textStyle">normal</item>
    <item name="android:textColor">#262626</item>
</style>

<style name="MainSearchButton">
    <item name="android:background">@drawable/main_edittext_button</item>
    <item name="android:textSize">16sp</item>
    <item name="android:textStyle">normal</item>
    <item name="android:textColor">#ff5500</item>
</style>

+main_edittext.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item 
        android:state_pressed="true" 
        android:drawable="@drawable/edit_text">

    <item 
        android:state_enabled="true" 
        android:state_focused="true"

    <item

Try to remove the padding and margins: android:layout_margin="0dp" and android:padding="0dp"

Also, per your comment, modify the minHeight to 0 as well: android:minHeight="0dp"
