how to maintain the speed of scroller?

Question:

I have a problem while using the scroller in my application.

I have used the scroller but it is not working properly as it is not able to maintain a consistent speed while automatically scrolling. The speed of the text is getting slower with time as the text moves upward.

Here is the code that I used for this purpose:

length = prompt_text.getLineCount(); Log.d("length",""+length); prompt_text.setScroller(scroll); scroll.startScroll(0,0,0,10 * length, 100000 / speedAmount);

Answer1:

Have you tried setting up the Scroller interpolator as a LinearInterpolator? <a href="http://developer.android.com/reference/android/widget/Scroller.html#Scroller(android.content.Context,%20android.view.animation.Interpolator" rel="nofollow">http://developer.android.com/reference/android/widget/Scroller.html#Scroller(android.content.Context,%20android.view.animation.Interpolator</a>)

Sample:

yourScroller = new Scroller(yourContext, new LinearInterpolator());
