If you simply want to scroll a textview, why dont you use TexViewObject.setMovementMethod(new ScrollingMovementMethod()) as suggested in this http://stackoverflow.com/questions/1748977/making-textview-scrollable-in-android — Kartik Domadiya, Feb 28 '12 at 11:47

In your activity Do something like this:

TextView textDisplayed =(TextView) findViewById(R.id.textView1);
textDisplayed.setMovementMethod(new ScrollingMovementMethod());

Hope this helps.

just add this in layout android:maxLines and android:scrollbars = "vertical" properties of textview in layout xml file. Then use the TexView.setMovementMethod(new ScrollingMovementMethod()) in .java – Goofy Feb 28 '12 at 11:58

Add a ViewGroup (like LinearLayout) between the ScrollView and your TextView. AFAIK, it's mandatory.

<?xml version="1.0" encoding="utf-8"?>

<ScrollView
    android:id="@+id/scrollView1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" >

    <LinearLayout
        android:id="@+id/linearLayout1"
        android:layout_width="match_parent"
        android:layout_height="match_parent" >


        <EditText
            android:id="@+id/editText1"
            android:layout_width="wrap_content"
            android:layout_height="352dp"
            android:layout_weight="1"
            android:inputType="textMultiLine" >

            <requestFocus />
        </EditText>

    </LinearLayout>
</ScrollView>

But it showing NULLpointer exception for me as its not able to find the texview id which is inside LL – Goofy Feb 28 '12 at 11:48
sorry the order should be different, LinearLayout->scrolliew->textview. are you sure calling the textview correctly in your code TextView tv = (TextView)findViewById(R.id.editText1); – Orlymee Feb 28 '12 at 11:54

this is absolutely fine to add scroview on textView but keep one thing in mind only height of textview should be more then scroll view height

<LinearLayout>

   <ScrollView >

      <TextView /> //textView 2

   </ScrollView> 
</LinearLayout>
