TextView Marquee Doesn't Work

Question

I've tried all, I can think of to get this marquee effect to work. Here is my xml:

<TextView android:id="@+id/curPlaying"
    android:layout_width="320dp"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true"
    android:ellipsize="marquee"
    android:scrollHorizontally="true"
    android:singleLine="true"
    android:marqueeRepeatLimit ="marquee_forever"
    android:focusable="true"
    android:focusableInTouchMode="true" 
    android:textColor="#83A602"
    android:textSize="20dp"
    android:text="Nothing Loaded" />

And I'm setting it as selected in code. The only thing why I think it might not be working is the text is getting modified by the code at relatively frequent intervals.

Help?

Hi Please try below code it is working fine for me...

<TextView
            android:id="@+id/mywidget"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentRight="true"
            android:ellipsize="marquee"
            android:fadingEdge="horizontal"
            android:lines="1"
            android:marqueeRepeatLimit="marquee_forever"
            android:scrollHorizontally="true"
            android:text="Simple application that shows how to use marquee, with a long text"
            android:textColor="#ff4500" />

TextView tv = (TextView) this.findViewById(R.id.mywidget);
        tv.setSelected(true); // Set focus to the textview

It is working on My Samsung Galaxy ACE Phone.

Just a note about the comment in the second code: "selected" != "focused". — Denis Gladkiy, Apr 20 '14 at 09:50

You could checkout Marquee feature of TextView in Android 1.1R1, that explains certains ways where marquee can have a problem in getting work. ScrollTextView - scrolling TextView for Android might be a good option.

  public class AlwaysMarqueeTextView extends TextView {

  public AlwaysMarqueeTextView(Context context) {
  super(context);
  }

  public AlwaysMarqueeTextView(Context context, AttributeSet attrs) {
  super(context, attrs);
  }

  public AlwaysMarqueeTextView(Context context, AttributeSet attrs, int defStyleAttr) {
  super(context, attrs, defStyleAttr);
  }

  @TargetApi(Build.VERSION_CODES.LOLLIPOP)
  public AlwaysMarqueeTextView(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
  super(context, attrs, defStyleAttr, defStyleRes);
  }

  @Override
  public boolean isFocused() {
  return true;
  }
  }

activity.xml

<ivar.kov.util.textViewUtil.AlwaysMarqueeTextView
  android:id="@+id/artist_tv2"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"

  android:singleLine="true"

If TextView fill whole width you need to add these lines of code

<TextView
    .
    .
    android:singleLine="true"
    android:ellipsize="marquee"
    android:marqueeRepeatLimit="marquee_forever"
    />

also do not forget to set selected for TexrtView as below

textview.setSelected(true);

and If TextView does not fill width the only thing is to call this method and pass TextView to it.

    fun addMarquee(textView: TextView) {
    textView.viewTreeObserver.addOnGlobalLayoutListener(object :
        ViewTreeObserver.OnGlobalLayoutListener {
        override fun onGlobalLayout() {
            val pixels = textView.measuredWidth - 1
            val params = textView.layoutParams
            params.width = pixels
            textView.layoutParams = params
            textView.isSelected = true
            textView.ellipsize = TextUtils.TruncateAt.MARQUEE
            textView.isSingleLine = true
            textView.marqueeRepeatLimit = -1
            textView.viewTreeObserver.removeOnGlobalLayoutListener(this)
        }
    })
}

NOTE: this method only work when textView width is wrap_content.
