How to animate button in android

Question

I am making an android app  and I have a button which leads to a messaging place  On the activity with the button  I check if there is any unread messages  and if so I want to do something to the button to let the user know that there is something unread   I was thinking of having the button sorta vibrate horizontally like 3 shakes every 2 or 3 seconds   I know how to run a thread in the background which does something every x milliseconds  But what I don t know what to do is shake it horizontally 3 times   Can anyone help with this   I was thinking of using the sin function  for the animation  I can use output from a sin function to get values that go up and down  which I can set the horizontal position of the button    But this seems too extreme  is there a better way

I can t comment on  omega s comment because I don t have enough reputation but the answer to that question should be something like   shake xml   lt  xml version  1 0  encoding  utf-8   gt   lt rotate xmlns android  http   schemas android com apk res android      android duration  100            lt  -- how long the animation lasts -- gt      android fromDegrees  -5          lt  -- how far to swing left -- gt      android pivotX  50               lt  -- pivot from horizontal center -- gt      android pivotY  50               lt  -- pivot from vertical center -- gt      android repeatCount  10          lt  -- how many times to swing back and forth -- gt      android repeatMode  reverse      lt  -- to make the animation go the other way -- gt      android toDegrees  5    gt          lt  -- how far to swing right -- gt    Class java  Animation shake   AnimationUtils loadAnimation this  R anim shake   view startAnimation shake     This is just one way of doing what you want  there may be better methods out there
