Question

i am begginer in android. In my app i am having textview which has multiple lines of text , it may have 15-20 lines. i want vertical auto scroll of text within that textview. so what can be the solution?

here is my xml code :

<LinearLayout 
    android:id="@+id/Thumbnail"
    android:layout_width="fill_parent"
    android:layout_height="200dp"
    android:paddingTop="10dp"
    android:paddingBottom="10dp"
    android:gravity="center"
    android:background="@drawable/imgres">
    <ScrollView      
        android:id="@+id/sv"     
        android:layout_width="fill_parent"     
        android:layout_height="fill_parent"    
        android:fillViewport="true" >

    <TextView 
    android:id="@+id/tv"
    android:layout_width="fill_parent"
    android:layout_height="200dp"
    android:background="#80000000"
    android:width="200dp"
    android:textStyle="bold"
    android:textColor="#ffffff"
    android:gravity="center"
    android:layout_alignParentTop="true" 
    android:focusable="true"
    android:focusableInTouchMode="true" 
    android:scrollbars = "vertical"
    android:maxLines="10"
    />    
   </ScrollView>
</LinearLayout>

In function i have set the text of my textview using code below :

tv.setText(textArray);

You don’t need to use a ScrollView actually.

Just set the

android:maxLines = "AN_INTEGER_NUMBER"

android:scrollbars = "vertical"

properties of your TextView in your layout’s xml file.

Then use:

yourTextView.setMovementMethod(new ScrollingMovementMethod())

in your code.
