Scrollable Textview Not working

I am trying to make a scrollable TextView where the user can scroll the updates.

I tried this:

XML: 

<TextView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:textAppearance="?android:attr/textAppearanceSmall"
    android:text=""
    android:scrollbars="vertical"
    android:id="@+id/updateText"
    android:background="#ce000000"
    android:textColor="#FFF"
    android:padding="12dp"
    android:textSize="13sp" />

and the code:

text.setMovementMethod(new ScrollingMovementMethod());
text.setText(updates.get(position).getUpdateText());

Yet it doesn't work properly.

It is laggy. Sometimes it works, but most of the time it doesn't.

Can anyone help?

I recommend you to use a ScrollView and then put inside this TextView.

<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:android="http://schemas.android.com/apk/res/android">

<TextView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:textAppearance="?android:attr/textAppearanceSmall"
    android:text=""
    android:scrollbars="vertical"
    android:id="@+id/updateText"
    android:background="#ce000000"
    android:textColor="#FFF"
    android:padding="12dp"
    android:textSize="13sp" />

Set the below attributes to your TextView

android:maxLines = "20" // any number
android:scrollbars = "vertical"

Also setMovementMethod() - 

 text.setMovementMethod(new ScrollingMovementMethod());
