Android animation for dynamically loaded image -


i want create animation image loaded vertical linear layout dynamically. when triggered image slide down alpha set 0 (this slide content below down hope) fade image in. being new android animations having trouble. right i'm trying fade in work, here have:

fade_in.xml

<?xml version="1.0" encoding="utf-8"?>  <alpha     xmlns:android="https://chemas.android.com/ap/res/android"     android:interpolator="@android:anim/anticipate_interpolator"     android:fromalpha="0.0"     android:toalpha="1.0"     android:duration="5000" > </alpha>

in activity:

animation animation = animationutils.loadanimation(context, r.anim.fade_in);  imageview image = new imageview(context); image.setimageresource(r.drawable.my_image); image.setlayoutparams(layoutparams); image.setalpha(0);  ((viewgroup) view).addview(image, 0);  image.startanimation(animation);

the image being loaded context below shifted down, if never fades in. working having image slide down dynamica add not choppy.

thanks in advance.

you have typo in xmlns:android tag.

it should be

xmlns:android = "http://schemas.android.com/apk/res/android"

with being corrected, remove image.setalpha(0); , should animate. afraid cannot give reason why doesn't work alpha attribute set 0.

regarding slide down animation, have subclass animation. have @ answer think can want: https://stackoverflow.com/a/5122460/871102
