i wanna play scale(from 0 -> 1) animation on 6 balls , duration is 1000 ms on each ball.
and each animation have to wait the previous for 200ms.
ex :
anim1.start -> delay 200ms -> anim2.start (while anim1 is playing) -> ........
but i always got all 6 balls animations started at the same time , i don't know why , could
somebody tell me??
// show animation.
public void showBallAnimation(View v) {
LinearLayout ll = (LinearLayout) findViewById(R.id.ball_container);
RelativeLayout rl;
ScaleAnimation scaleAnim1 = new ScaleAnimation(0.0f, 1.0f, 0.0f, 1.0f);
scaleAnim1.setDuration(500);
scaleAnim1.setStartOffset(0);
scaleAnim1.setFillAfter(true);
rl = (RelativeLayout) ll.getChildAt(0);
rl.setVisibility(View.VISIBLE);
rl.startAnimation(scaleAnim1);
ScaleAnimation scaleAnim2 = new ScaleAnimation(0.0f, 1.0f, 0.0f, 1.0f);
scaleAnim2.setDuration(500);
scaleAnim2.setStartOffset(200);
scaleAnim2.setFillAfter(true);
rl = (RelativeLayout) ll.getChildAt(1);
rl.setVisibility(View.VISIBLE);
rl.startAnimation(scaleAnim2);
ScaleAnimation scaleAnim3 = new ScaleAnimation(0.0f, 1.0f, 0.0f, 1.0f);
scaleAnim3.setDuration(500);
scaleAnim3.setStartOffset(400);
scaleAnim3.setFillAfter(true);
rl = (RelativeLayout) ll.getChildAt(2);
rl.setVisibility(View.VISIBLE);
rl.startAnimation(scaleAnim3);
// Animation anim4 =
// AnimationUtils.loadAnimation(getApplicationContext(),
// R.anim.ball_scale4);
ScaleAnimation scaleAnim4 = new ScaleAnimation(0.0f, 1.0f, 0.0f, 1.0f);
scaleAnim4.setDuration(500);
scaleAnim4.setStartOffset(600);
scaleAnim4.setFillAfter(true);
rl = (RelativeLayout) ll.getChildAt(3);
rl.setVisibility(View.VISIBLE);
rl.startAnimation(scaleAnim4);
}
You should change r1.startAnimation(scaleAnimX) to r1.setAnimation(scaleAnimX)
Calling startAnimation() will start the Animation instantly, ignoring any time offset or start time.
Calling setAnimation() will take into account any time specifications.

I have an activity, and on onCreate I run this piece of code:
AnimationSet animation = new AnimationSet(true);
animation.addAnimation(new AlphaAnimation(0f, 1f));
animation.addAnimation(new ScaleAnimation(0f, 1f, 0f, 1f, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f));
animation.setDuration(4000); // should be 300
animation.setFillAfter(true);
View i1 = findViewById(R.id.load_mainimg);
View i2 = findViewById(R.id.load_text1);
View i3 = findViewById(R.id.load_text2);
View i4 = findViewById(R.id.load_imgbtn_about);
View i5 = findViewById(R.id.load_imgbtn_settings);
View i6 = findViewById(R.id.load_btn1);
View i7 = findViewById(R.id.load_btn2);
i1.startAnimation(animation);
...
i7.startAnimation(animation);
However, the TextViews (i2, i3) and the ImageButtons (i4, i5) doesn't scale from the center. (i1 is an ImageView, i6 and i7 are LinearLayouts.) What am I doing wrong?
I have a case where I have 2 edittext email and password. When any one gets focus say email the hint moves up and becomes the heading. In this animation i translate the textview(hint) up and at the same time scale it down to 0.8f.
At the same time the second textview say password looses focus, if its still empty i want to reverse the animation and put back the heading as hint.
To sum up hint moves up as heading and gets back to hint position if the edittext remains empty.
I have two different animation set for both the editText views, they work well individually but on parallel execution one of them doesnt show up instead the hint becomes invisible.
My code is as follows :
email.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View view, boolean b) {
if(b && emailAnimated==false){
Log.d("email1", "called");
AnimationSet animSet = new AnimationSet(true);
animSet.setFillAfter(true);
animSet.setFillEnabled(true);
animSet.setDuration(800);
TranslateAnimation translate = new TranslateAnimation(0, 0, 0, -60);
animSet.addAnimation(translate);
ScaleAnimation scale = new ScaleAnimation(1f, 0.8f, 1f, 0.8f);
animSet.addAnimation(scale);
emailText.startAnimation(animSet);
emailAnimated=true;
}else if(emailAnimated==true)
{
Log.d("email2", "called");
AnimationSet animSet = new AnimationSet(true);
animSet.setFillAfter(true);
animSet.setFillEnabled(true);
animSet.setDuration(800);
TranslateAnimation translate = new TranslateAnimation(0, 0, 0, -60);
animSet.addAnimation(translate);
ScaleAnimation scale = new ScaleAnimation(1f, 0.8f, 1f, 0.8f);
animSet.addAnimation(scale);
//Reverse the animation if losses focus
animSet.setInterpolator(new ReverseInterpolator());
emailText.startAnimation(animSet);
emailAnimated=false;
}
}
});
password.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View view, boolean b) {
if(b && passwordAnimated==false){
Log.d("pass1", "called");
AnimationSet animSet = new AnimationSet(true);
animSet.setFillAfter(true);
animSet.setFillEnabled(true);
animSet.setDuration(800);
TranslateAnimation translate = new TranslateAnimation(0, 0, 0, -60);
animSet.addAnimation(translate);
ScaleAnimation scale = new ScaleAnimation(1f, 0.8f, 1f, 0.8f);
animSet.addAnimation(scale);
passwordText.startAnimation(animSet);
passwordAnimated=true;
}
else if(passwordAnimated==true)
{
Log.d("pass2", "called");
AnimationSet animSet = new AnimationSet(true);
animSet.setFillAfter(true);
animSet.setFillEnabled(true);
animSet.setDuration(800);
TranslateAnimation translate = new TranslateAnimation(0, 0, 0, -60);
animSet.addAnimation(translate);
ScaleAnimation scale = new ScaleAnimation(1f, 0.8f, 1f, 0.8f);
animSet.addAnimation(scale);
animSet.setInterpolator(new ReverseInterpolator());
passwordText.startAnimation(animSet);
passwordAnimated=false;
}
}
});
Just to make it more understandable, else if condition of email will be called whenever if condition of password is true and vies versa and thats how 2 animation sets are called.
You can try to set the layer type of the two EditTexts to hardware while animating.
animSet.setAnimationListener(new AnimationListener() {
#Override
public void onAnimationStart( Animation animation ) {
emailText.setLayerType(View.LAYER_TYPE_HARDWARE, null);
}
#Override
public void onAnimationRepeat( Animation animation ) {
}
#Override
public void onAnimationEnd( Animation animation ) {
emailText.setLayerType(View.LAYER_TYPE_NONE, null);
}
});
I am using a ViewFlipper to display a series of images, however the animation I am trying to apply (zoom+fade) is only shown on the very last image in the ViewFlipper. Anyone know where I'm going wrong? Below is my code:
mViewFlipper = (ViewFlipper) fragmentView.findViewById(R.id.view_flipper);
mViewFlipper.setVisibility(View.VISIBLE);
for(int i=0;i<galleryGridImages.size();i++)
{
setFlipperImage(galleryGridImages.get(i));
}
AnimationSet as = new AnimationSet(false);
fade = new AlphaAnimation(1.0f,0.0f);
fade.setDuration(transitionSpeed);
as.addAnimation(fade);
zoom = new ScaleAnimation(1, 3, 1, 3, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
zoom.setDuration(transitionSpeed);
as.addAnimation(zoom);
mViewFlipper.setOutAnimation(as);
mViewFlipper.setAutoStart(true);
mViewFlipper.setFlipInterval(interval);
mViewFlipper.startFlipping();
public void animateScreenOn() {
CellLayout layout = (CellLayout) getChildAt(getCurrentPage());
if (layout != null) {
int count = layout.getPageChildCount();
for (int i = count-1; i>=0; i--) {
View v = layout.getPageChild(i);
v.setScaleX(0.95f);
v.setScaleY(0.95f);
AnimatorSet set = new AnimatorSet();
ObjectAnimator animation1 = LauncherAnimUtils.ofPropertyValuesHolder(v,
PropertyValuesHolder.ofFloat("scaleX", 1.0f));
animation1.setDuration(1000L);
animation1.setInterpolator(new BounceInterpolator());
ObjectAnimator animation2 = LauncherAnimUtils.ofPropertyValuesHolder(v,
PropertyValuesHolder.ofFloat("scaleY", 1.0f));
animation2.setDuration(500L);
animation2.setInterpolator(new BounceInterpolator());
List<Animator> items = new ArrayList<Animator>();
items.add(animation1);
items.add(animation2);
set.playTogether(items);
set.setStartDelay((count-1-i)*100L);
set.start();
}
}
}
this code have an issue. the time of this code cost is different on different devices, some is ok, but some will be too short, so i need to change animate time depend on device refresh rate. anyone can tell me how to get it from android code, 3X!
I am creating an animation where my image will translate to a different spot on the screen and then fade in gradually. I completed the translation part(see below) but now when I start the fade in animation it disappears for the duration and then reapears after. I want to show the image being faded in gradually....Any ideas why this is happening?
public static int moveTwo(AnimationListener activity, View apa, int animationmove)
Log.v("MOVETWO", "Started move2");
AnimationSet picMov2 = new AnimationSet(true);
picMov2.setAnimationListener(activity);
RotateAnimation rotate2 = new RotateAnimation(0, 0,
Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF,
0.5f);
// rotate1.setStartOffset(50);
rotate2.setDuration(2000);
picMov2.addAnimation(rotate2);
TranslateAnimation trans2 = new TranslateAnimation(-200, -400, 0, 0);
trans2.setDuration(2000);
picMov2.setFillAfter(true);
picMov2.addAnimation(trans2);
apa.startAnimation(picMov2);
animationmove = 3;
return animationmove;
public static int moveThree(AnimationListener activity, View apa, int animationmove)
AlphaAnimation fadein = new AlphaAnimation((float) 0.3, 1);//HERE THE IMAGE IS DISAPPEARING
fadein.setAnimationListener(activity);
fadein.setDuration(2000);
fadein.setFillAfter(true);
apa.startAnimation(fadein);
animationmove=4;
return animationmove;
Just needed to create a translate action in the same place so it doesn't go back to its original position
public static int moveThree(AnimationListener activity, View apa, int animationmove)
{
Log.v("MOVETHREE", "Started move3");
AnimationSet picMov3 = new AnimationSet(true);
picMov3.setAnimationListener(activity);
AlphaAnimation fadein = new AlphaAnimation((float) 0.4, 1);
// rotate1.setStartOffset(50);
fadein.setDuration(duration);
picMov3.addAnimation(fadein);
TranslateAnimation trans1 = new TranslateAnimation(-400, -400, 0, 0);
trans1.setDuration(duration);
picMov3.setFillAfter(true);
picMov3.addAnimation(trans1);
apa.startAnimation(picMov3);
