How to make the text of a scroll view start at the bottom and work it's way up?

I'm trying to make a texting application and I want the text to start at the bottom and work it's way up instead of vice versa. I've tried ScrollView.Focus_UP AND down and text alignment end. But it's not working. Why? Again, Sorry if this is a repost. I couldn't find anything on it, maybe I'm wording my question wrong.

<ScrollView 
    android:id="@+id/outputScrollView"

    android:isScrollContainer="false"
    android:layout_width="fill_parent"
    android:layout_height="0dp" 
    android:layout_weight="1"  >
    <RelativeLayout android:id="@+id/relchatlay"
     android:layout_width="match_parent"
         android:layout_height="match_parent"
        android:layout_alignParentBottom="true"
        >
    <TextView 
        android:id="@+id/outputTextView"
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content"
        android:paddingLeft="5dp" 
        android:paddingRight="5dp" 
        android:textColor="#FFFFFF"
        android:paddingTop="5dp"
        android:layout_alignParentBottom="true"

        />
    </RelativeLayout>
    </ScrollView>


public void onSendClicked(View view){
    outputScrollView.fullScroll(ScrollView.FOCUS_DOWN);
    outputScrollView.setTextAlignment(ScrollView.TEXT_ALIGNMENT_TEXT_START);
    theClient.sendChat(inputEditText.getText().toString());
    inputEditText.setText("");
