Android LinearLayout Selector background color

You can add:

android:clickable="true"

to LinearLayout.

I am using a linear layout as a button however, I do not have anything assigned as clickable or not and it seems to work just fine. I have set up a style for my standard button and I just assign that style to the linear layout like I would any other button.

The linearlayout as a button:

<LinearLayout
    style="@style/btn_stand"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:onClick="onClickLLButton"
    android:orientation="vertical" >

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:text="Button Label" />

    <TextView
        android:id="@+id/tvLLButton"
        android:layout_height="0px"
        android:layout_weight="1"
        android:gravity="center"
        android:text="Button Info" />
</LinearLayout>

My style definition for the button:

<style name="btn_stand" parent="AppBaseTheme">
    <item name="android:background">@drawable/btn_stand_sel</item>
    <item name="android:textColor">@drawable/btn_stand_text_color</item>
    <item name="android:minHeight">48dp</item>
    <item name="android:paddingLeft">5dp</item>
    <item name="android:paddingRight">5dp</item>
</style>

My @drawable/btn_stan_sel file:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <!-- disabled state -->
    <item android:drawable="@drawable/btn_stand_disabled" android:state_enabled="false"/>

    <!-- enabled and pressed state -->
    <item android:drawable="@drawable/btn_stand_pressed" android:state_enabled="true" android:state_pressed="true"/>

    <!-- enabled and focused state -->
    <item android:drawable="@drawable/btn_stand_focused" android:state_enabled="true" android:state_focused="true"/>

    <!-- enabled state -->
    <item android:drawable="@drawable/btn_stand_enabled" android:state_enabled="true"/>

</selector>

My drawable file repeated for each state just with different colors for each state:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" >

    <stroke
        android:width="1dp"
        android:color="@color/stroke" />

    <solid android:color="@color/blue" />

    <corners android:radius="6dp" />

</shape>
