<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/MainLayout"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <RelativeLayout
        android:id="@+id/smsItemContainerRelativeLayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >

        <TextView
            android:id="@+id/textView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentTop="true"
            android:layout_centerInParent="true"
            android:layout_gravity="center_horizontal|top"
            android:text="SMS Inbox"
            android:textAppearance="?android:attr/textAppearanceMedium" />

        <TextView
            android:id="@+id/unread_count"
            android:layout_width="wrap_content"

            android:layout_toRightOf="@+id/textView"
            android:background="@drawable/notification_bg"
            android:gravity="center"

Answer 1

add this in your textview of id unread_count

don't give negative margin

add some right margin to adjust position of your textview

Answer 2

Just set android:layout_alignParentRight="true"

and try with this

android:gravity="right"
android:textAlignment="gravity"
