<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:id="@+id/mbContainer"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:layout_margin="10dp"    android:gravity="bottom"    android:orientation="vertical" >    <LinearLayout        style="@style/bgTheme"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:layout_margin="10dp"        android:gravity="bottom"        android:orientation="vertical" >        <TextView            android:id="@+id/mbMessage"            android:layout_width="fill_parent"            android:layout_height="wrap_content"            android:text="Test"            android:textColor="@drawable/white" />    </LinearLayout></LinearLayout>
