Automatic animation
I have a开发者_StackOverflow ImageView that needs to be slide in from the bottom. Remain there for 5 sec. And then slide out. How do I do that? There is no user intervention.
Thanks Rajesh Muthu
Ok I found out a solution. Create an xml in anim folder called popup_slider.xml
<set xmlns:android="http://schemas.android.com/apk/res/android" android:shareInterpolator="true">
<alpha android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="100" />
<translate android:fromYDelta="100%p" android:toYDelta="0%p" android:startOffset="1000" android:duration="5000" android:zAdjustment="top"/>
<alpha android:fromAlpha="0.99" android:toAlpha="1.0" android:startOffset="6000" android:duration="5000" />
<translate android:fromYDelta="0%p" android:toYDelta="100%p" android:startOffset="11000" android:duration="5000" android:zAdjustment="bottom"/>
<alpha android:fromAlpha="1.0" android:toAlpha="0.0" android:startOffset="16000" android:duration="1000" />
</set>
In Java implement AnimationListener
public static void popUpAndDownAnimation(View v) {
Animation animation = AnimationUtils.loadAnimation(localContext, R.anim.popup_slider);
animation.setAnimationListener(new Animation.AnimationListener(){
public void onAnimationEnd(Animation arg0) {
popUpAdvertisementView.setVisibility(View.GONE);
}
public void onAnimationRepeat(Animation animation) {
// TODO Auto-generated method stub
}
public void onAnimationStart(Animation animation) {
popUpAdvertisementView.setVisibility(View.VISIBLE);
}
});
v.startAnimation(animation);
}
Android has a set of animation classes for simple animations on Views. What you're looking for is a tween animation. They provide an example, and it sounds like you could do most of it in XML. Good luck ^_^
