And how can I add the marquee effect on my text view? Can I make text view scrolling from right to left?

Answer 1

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.

Kotlin

    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)
        }
    })
}

Java

public void addMarquee(TextView textView) {
    textView.getViewTreeObserver().addOnGlobalLayoutListener(
            new ViewTreeObserver.OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {

            int pixels = textView.getMeasuredWidth() - 1;
            ViewGroup.LayoutParams params = textView.getLayoutParams();
            params.width = pixels;
            textView.setLayoutParams(params);
            textView.setSelected(true);
            textView.setEllipsize(TextUtils.TruncateAt.MARQUEE);
            textView.setSingleLine(true);
            textView.setMarqueeRepeatLimit(-1);
            textView.getViewTreeObserver().removeOnGlobalLayoutListener(this);
        }
    });
}

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