Android automatic horizontally scrolling TextView

After these xml code as answered by @rajat

<TextView
        android:text="Single-line text view that scrolls automatically if the text is too long to fit in the widget" 
        android:singleLine="true" 
        android:ellipsize="marquee"
        android:marqueeRepeatLimit ="marquee_forever"
        android:focusable="true"
        android:focusableInTouchMode="true" 
        android:scrollHorizontally="true"
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content"/>

We need to set

TextView tv=(TextView)findViewById(R.id.textview1);
  tv.setSelected(true); 

which finally made mine work

If you don't need to sub-class the TextView, you can try this in your layout file:

    <TextView
        android:text="Single-line text view that scrolls automatically if the text is too long to fit in the widget" 
        android:singleLine="true"
        android:ellipsize="marquee"
        android:marqueeRepeatLimit ="marquee_forever"
        android:focusable="true"
        android:focusableInTouchMode="true" 
        android:scrollHorizontally="true"
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content"/>

Also, in your code use the following:

findViewById(R.id.serviceColorCode).setSelected(true);
