Is there a way to make ellipsize="marquee" always scroll?

Question

I want to use the marquee effect on a TextView, but the text is only being scrolled when the TextView gets focus. That's a problem, because in my case, it can't.

I am using:

  android:ellipsize="marquee"
  android:marqueeRepeatLimit="marquee_forever"

Is there a way to have the TextView always scroll its text? I've seen this being done in the Android Market app, where the app name will scroll in the title bar, even if it doesn't receive focus, but I couldn't find this being mentioned in the API docs.

Answer 1

Try to set the focus of the TextView manually

Answer 2

I have been facing the problem and the shortest solution I have come up with is to create a new class derived from TextView. The class should override three methods onFocusChanged, onWindowFocusChanged and isFocused to make the TextView all focused.

@Override
protected void onFocusChanged(boolean focused, int direction, Rect previouslyFocusedRect) {
    if(focused)
        super.onFocusChanged(focused, direction, previouslyFocusedRect);
}

@Override
protected void onWindowFocusChanged(boolean focused) {
    if(focused)
        super.onWindowFocusChanged(focused);
}


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

I don't know if you still need the answer, but I found an easy way to do this.

Set up your animation like so:

Animation mAnimation = new TranslateAnimation(START_POS_X, END_POS_X, 
                START_POS_Y, END_POS_Y);
mAnimation.setDuration(TICKER_DURATION); 
mAnimation.setRepeatMode(Animation.RESTART);
mAnimation.setRepeatCount(Animation.INFINITE);

START_POS_X, END_POS_X, START_POS_Y and END_POS_Y are float values, while TICKER_DURATION is an int I declared with my other constants.

Then you can now apply this animation to your TextView:

TextView tickerText = (TextView) findViewById(R.id.ticker);
tickerText.setAnimation(mAnimation);

And that's it. :)

My animation starts on the right side off-screen (300f) and ends on the left side off-screen(-300f), with a duration of 15s (15000).

    Just put these parameters in your TextView. It works :)

    android:singleLine="true" 
    android:ellipsize="marquee"
    android:marqueeRepeatLimit ="marquee_forever"
    android:scrollHorizontally="true"
    android:focusable="true"
    android:focusableInTouchMode="true"
