Android - Center Textview in LinearLayout

Question

I am trying to center a TextView in a LinearLayout and it is centering horizontaly but not vertically.

below is my code

 <LinearLayout
        android:orientation="vertical"
        android:layout_width="320dp"
        android:layout_height="50dp"
        android:background="@drawable/rectblack"
        android:layout_marginTop="10dp"
        android:layout_gravity="center"
        android:minWidth="25px"
        android:minHeight="25px">
        <TextView
            android:text="Explode a Vin"
            android:gravity="center"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:id="@+id/tvExVin" />
    </LinearLayout>

In the end I would like it to be centered vertically to the left of the Linearlayout, if someone could figure out how to do that, that would be great.

Thanks!

You have the gravity and layout_gravity reversed. You can have multiple values on the gravity attribute separated by "|". Try this:

 <LinearLayout
        android:orientation="vertical"
        android:layout_width="320dp"
        android:layout_height="50dp"
        android:background="@drawable/rectblack"
        android:layout_marginTop="10dp"
        android:layout_gravity="center_horizontal"
        android:gravity="center_vertical|left"
        android:minWidth="25px"
        android:minHeight="25px">
        <TextView
            android:text="Explode a Vin"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:id="@+id/tvExVin" />
    </LinearLayout>

For clarification:

android:layout_gravity="center_horizontal" will center the LinearLayout horizontally in its parent.

android:gravity="center_vertical|left" will center the TextView (and any other children) vertically inside the LinearLayout and align it to the left.
