</RelativeLayout>

This is my Activity,

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.player);

songTitleLabel = (TextView) findViewById(R.id.songTitle);

GENRE = getIntent().getExtras().getString("genre");

        songTitleLabel.setSelected(true);
        songTitleLabel.setEllipsize(TruncateAt.END); 
        songTitleLabel.setEllipsize(TruncateAt.MARQUEE);
        songTitleLabel.setText(GENRE);
        songTitleLabel.setSingleLine(true);

But it is not working. Please help me to find out what I am missing here.

Answer 1

I have posted the answer for what i mentioned in the comment.

Though the code you wrote for implementing the Marquee is fine and correct, we need to mind that,

The text, that will be shown should be greater than the length of the device screen width or need to fix the width less than the length of the incoming string, whether it may be static or dynamic text.

Thank you for mentioning, @devraj.
