It's easy if you want to limit TextView's height by line, use android:maxLines:

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:maxLines="5"
    android:scrollbars="vertical"
    android:requiresFadingEdge="vertical" />

In your code, write as below:

yourTextView.setMovementMethod(new ScrollingMovementMethod());

With this code, your TextView can be scrolled vertically when the text is longer than the maxLines.

Try like this.

XML

<TextView
   android:id="@+id/descTxtView"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:maxLines="5"
   android:scrollbars="vertical"
   android:text="Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry&apos;s standard dummy text ever since the 1500s."
   android:textColor="#232e3b"
   android:typeface="sans" />

in JAVA

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