How do I make imageView rotate and translate around itself at the same time?[android]

On touch apple "falls" (translates) down from a tree and should rotate around itself and translate.
Animation apple3_anim = AnimationUtils.loadAnimation(this,
R.anim.apple3_animation);
apple3.startAnimation(apple3_anim);
RotateAnimation r = new RotateAnimation(0.0f,
720.0f, Animation.RELATIVE_TO_SELF,
0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
r.setDuration(2000);
apple3.startAnimation(r);
the xml code for apple3_animation.xml file:
<?xml version="1.0" encoding="utf-8"?>
<translate
android:fromXDelta="0"
android:toXDelta="0"
android:fromYDelta="0"
android:toYDelta="450"
android:duration="1200"
>
</translate>
The issue is that the animations don't happen sequentially,only the last 'r' animation gets executed - the apple rotates around itself 720degrees.
How do I make it go sequentially? even if i put all things in xml file, in the xml , only the last animation gets executed!

using animator can solve it quikely
apple3.animate().translationY(450).setDuration(1200).setListener(new AnimatorListenerAdapter() {
#Override
public void onAnimationEnd(Animator animation) {
super.onAnimationEnd(animation);
iv.animate().rotation(720).setDuration(2000);
}
}).start();

Start two animation in the same Layout

Im trying to do an alpha and translate in a RelativeLayout. I define both:
AlphaAnimation alpha;
alpha = new AlphaAnimation(0.0f, 1.0f);
alpha.setDuration(1500);
alpha.setFillAfter(true);
TranslateAnimation translate;
translate = new TranslateAnimation(Animation.RELATIVE_TO_SELF, 0,
Animation.RELATIVE_TO_SELF, 0,
Animation.RELATIVE_TO_SELF, 1,
Animation.RELATIVE_TO_SELF, 0);
translate.setDuration(1000);
So I start the animation in my RelativeLayout
RelativeLayout.startAnimation(translate);
RelativeLayout.startAnimation(alpha);
The problem is that in this case, only the alpha animation start and not the translation. Can someone help me? The question is how can I start two different animations at the same time in the same object(Relative Layout in my case)
I resolve the question. I added it:
AnimationSet animationSet = new AnimationSet(true);
animationSet.addAnimation(alpha);
animationSet.addAnimation(translate);
RelativeLayout.startAnimation(animationSet);

You can use animation set ıf you want to run two animation in the same time:
http://developer.android.com/reference/android/view/animation/AnimationSet.html
For exeample;
as = new AnimationSet(true);
as.setFillEnabled(true);
as.setInterpolator(new BounceInterpolator());
TranslateAnimation ta = new TranslateAnimation(-300, 100, 0, 0);
ta.setDuration(2000);
as.addAnimation(ta);
TranslateAnimation ta2 = new TranslateAnimation(100, 0, 0, 0);
ta2.setDuration(2000);
ta2.setStartOffset(2000); // allowing 2000 milliseconds for ta to finish
as.addAnimation(ta2);

Your current code won't work, because as soon as the first animation starts, the second one ends it and starts itself. So you need to wait till it's done.
Try this :
translate.setAnimationListener(new AnimationListener() {
public void onAnimationStart(Animation animation) {
// TODO Auto-generated method stub
}
public void onAnimationRepeat(Animation animation) {
// TODO Auto-generated method stub
}
public void onAnimationEnd(Animation animation) {
// TODO Auto-generated method stub
RelativeLayout.startAnimation(alpha);
}
});
If you want to execute them simultaneously, I'd suggest you create an animation.xml file in your res/anim/ folder.
Example:
<?xml version="1.0" encoding="utf-8"?>
<set
xmlns:android="http://schemas.android.com/apk/res/android">
<scale
android:fromXScale="1.0"
android:fromYScale="1.0"
android:toXScale=".75"
android:toYScale=".75"
android:duration="1500"/>
<rotate
android:fromDegrees="0"
android:toDegrees="360"
android:duration="1500"
android:pivotX="50%"
android:pivotY="50%" />
<scale
android:fromXScale=".75"
android:fromYScale=".75"
android:toXScale="1"
android:toYScale="1"
android:duration="1500"/>
</set>
Java Code:
Animation multiAnim = AnimationUtils.loadAnimation(this, R.anim.animation);
RelativeLayout.startAnimation(multiAnim);

Rotating an ImageVIew should be CLICKED in its rotated position in android below HoneyComb versions

I am trying rotate an ImageView along with its original location (rotating the image aswell as the view). So that After rotation, when I click on the rotated Image in its current position, it should be able clicked in the rotated location only.
For this solution I am trying the following code. However it is rotating is going fine. After the rotation end I need to place the ImageView and Image in the rotated Location to make it able click over there only. But it is not going successfully. I am unable to rotated Image location axis points to place correctly. Can any one please suggest a way to resolve this issue.
fyi-It should work on Gingerbread version android-9
aniView1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Log.e("", "Clicked on IMAGE VIEW - 1");
}
});
RotateAnimation rotate5 = new RotateAnimation(0, 150,
Animation.INFINITE, 100, Animation.INFINITE, 250);
//rotate5.setFillAfter(true);
rotate5.setDuration(2000);
rotate5.setInterpolator(new LinearInterpolator());
aniView1.setAnimation(rotate5);
rotate5.setAnimationListener(new Animation.AnimationListener() {
#Override
public void onAnimationStart(Animation animation) {
}
#Override
public void onAnimationRepeat(Animation animation) {
}
#Override
public void onAnimationEnd(Animation animation) {
int newTop = (int) (aniView1.getTop() + aniView1.getWidth());
aniView1.layout(aniView1.getLeft()-200, newTop,
aniView1.getRight(),
aniView1.getBottom() + aniView1.getMeasuredWidth());
// aniView1.setLayoutParams(new
// RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT,RelativeLayout.LayoutParams.WRAP_CONTENT));
}
});

Try this. It had worked for me. Animated state will be persisted from that
Edited:
Ok, and I am able to do that with this code in my app:
Animation rotateAnim = new RotateAnimation(0, 360, Animation.ABSOLUTE, Animation.ABSOLUTE, Animation.ABSOLUTE, Animation.RELATIVE_TO_SELF);
rotateAnim.setDuration(5000);
rotateAnim.setRepeatCount(1);
rotateAnim.setInterpolator(new AccelerateInterpolator());
rotateAnim.setRepeatMode(Animation.REVERSE);
rotateAnim.setFillEnabled(true);
rotateAnim.setFillAfter(true);

Put this file under android res --> anim --> loading_rotation.xml
<?xml version="1.0" encoding="UTF-8"?>
<rotate
xmlns:android="http://schemas.android.com/apk/res/android"
android:fromDegrees="0"
android:toDegrees="360"
android:pivotX="50%"
android:pivotY="50%"
android:repeatCount="infinite"
android:duration="1200"
android:interpolator="#android:anim/linear_interpolator"/>
and in your activity
view.startAnimation(AnimationUtils.loadAnimation(context,
R.anim.loading_rotation));
and where you want to stop just call
view.clearAnimation();

Android gallery slideshow animation

I'm developing a gallery app, in this app I'm displaying images in slideshow using gallery. It's working fine, but I want to add some animation. I can apply only one animation with this code but I want to add two animation effects in gallery view.
Say in translation effect, right-to-center and center-to-left. Please anyone help me out.
public void slidShow(){
Runnable runnable = new Runnable() {
#Override
public void run() {
myslideshow();
handler.postDelayed(this, 3000);
}
};
new Thread(runnable).start();
}
private void myslideshow(){
PicPosition = gallery.getSelectedItemPosition() +1;
if (PicPosition >= bitmaps.size()){
PicPosition = gallery.getSelectedItemPosition(); //stop
}
else{
Animation inFromRight = new TranslateAnimation(
Animation.RELATIVE_TO_PARENT, +1.0f,
Animation.RELATIVE_TO_PARENT, 0.0f,
Animation.RELATIVE_TO_PARENT, 0.0f,
Animation.RELATIVE_TO_PARENT, 0.0f);
inFromRight.setDuration(500);
inFromRight.setInterpolator(new AccelerateInterpolator());
gallery.startAnimation(inFromRight);
gallery.setSelection(PicPosition);
}
}

Use Xml based animation
Create a Xml file in folder res/anim/animate.xml
put the code
<set xmlns:android="http://schemas.android.com/apk/res/android" android:shareInterpolator="true">
<translate
android:fromXDelta="0%p" android:toXDelta="50%p" // change this to decide the range
android:duration="500" android:startOffset="0"/>
<translate
android:fromXDelta="0%p" android:toXDelta="100%p"
android:duration="500" android:startOffset="500"/>// change this to increase the
time for image to stay
</set>
now in your function myslideshow() change
Animation inFromRight = AnimationUtils.loadAnimation(this, R.anim.animate);
gallery.startAnimation(inFromRight);
gallery.setSelection(PicPosition);
Thats all.....

Android Animation one after other

I have two TranslateAnimations on a TextView and I want them to execute one after other. However, by using the code below, only the second one is executed.
How can I solve this?
TranslateAnimation animation = new TranslateAnimation(
Animation.ABSOLUTE, 0.0f, Animation.ABSOLUTE, 0.0f,
Animation.ABSOLUTE, 0.0f, Animation.ABSOLUTE, -150.0f);
animation.setDuration(200);
wave.startAnimation(animation);
TranslateAnimation animation1 = new TranslateAnimation(
Animation.ABSOLUTE, 0.0f, Animation.ABSOLUTE, 0.0f,
Animation.ABSOLUTE, 150.0f, Animation.ABSOLUTE, 0.0f);
animation1.setDuration(200);
wave.startAnimation(animation1);

Link them together with
Animation Set
AnimationSet as = new AnimationSet(true)
TranslateAnimation animation = new TranslateAnimation(
Animation.ABSOLUTE, 0.0f, Animation.ABSOLUTE, 0.0f,
Animation.ABSOLUTE, 0.0f, Animation.ABSOLUTE, -150.0f);
animation.setDuration(200);
as.addAnimation(animation);
TranslateAnimation animation1 = new TranslateAnimation(
Animation.ABSOLUTE, 0.0f, Animation.ABSOLUTE, 0.0f,
Animation.ABSOLUTE, 150.0f, Animation.ABSOLUTE, 0.0f);
animation1.setDuration(200);
animation1.setStartOffset(200);
as.addAnimation(animation1);
wave.startAnimation(as);

EDIT: Andy Boots answer below is the better answer imo.
Just set your first one like this and it'll start the other one, once the animation finishes:
animation.setAnimationListener(new AnimationListener() {
#Override
public void onAnimationStart(Animation animation) {
// TODO Auto-generated method stub
}
#Override
public void onAnimationRepeat(Animation animation) {
// TODO Auto-generated method stub
}
#Override
public void onAnimationEnd(Animation animation) {
wave.startAnimation(animation1);
}
});
edit: The reason only your second animation is executed with your current code, is because it overrides the playing of the first animation (both actually are played, but you only see the latest one to start). If you do like I wrote, they will play sequentially instead of in parallel.

also you can do this by XML itself using android:startOffset attribute , and there is an examble:
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<scale
android:duration="300"
android:fromXScale="0%"
android:fromYScale="0%"
android:pivotX="50%"
android:pivotY="50%"
android:toXScale="100%"
android:toYScale="100%" />
<alpha
android:duration="300"
android:fromAlpha="0"
android:toAlpha=".5" />
<alpha
android:duration="300"
android:fromAlpha=".5"
android:startOffset="300"
android:toAlpha="1" />
</set>

There is one more approach to reach this goal which can be useful when you need to animate a lot of views one after another. You can use setStartOffset method to set a delay before animation begins. So, if you know, how much time will take for your first animation to end, you can set this as a delay for your second animation. This is an example where I animated six ImageButtons and six TextViews below them one after another:
public void animateButtons() {
// An array of buttons
int[] imageButtonIds = {R.id.searchButton, R.id.favoriteButton, R.id.responseButton, R.id.articleButton, R.id.resumeButton, R.id.subscribeButton};
// Array of textViews
int[] textViewIds = {R.id.searchTextView, R.id.favoriteTextView, R.id.responseTextView, R.id.articleTextView, R.id.resumeTextView, R.id.subscribeTextView};
int i = 1;
for (int viewId : imageButtonIds) {
ImageButton imageButton = (ImageButton) findViewById(viewId);
// Animation from a file fade.xml in folder res/anim
Animation fadeAnimation = AnimationUtils.loadAnimation(this, R.anim.fade);
// Delay for each animation is 100 ms bigger than for previous one
fadeAnimation.setStartOffset(i * 100);
imageButton.startAnimation(fadeAnimation);
// The same animation is for textViews
int textViewId = textViewIds[i-1];
TextView textView = (TextView) findViewById(textViewId);
textView.startAnimation(fadeAnimation);
i ++;
}
}
In my res/anim folder I have a file, called fade.xml with these contents:
<?xml version="1.0" encoding="utf-8"?>
<!-- Fade animation with 500 ms duration -->
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="#android:anim/accelerate_decelerate_interpolator"
android:fromAlpha="0.0" android:toAlpha="1.0"
android:duration="500" />

Create an animation array and use method for creating AnimationSet.
Animation[] animations = {
getScaleAnimation(0.4f, 1.3f, 2000),
getScaleAnimation(1.3f, 1.0f, 500),
getScaleAnimation(0.4f, 1.3f, 1000),
getScaleAnimation(1.3f, 1.0f, 3000),
getScaleAnimation(0.4f, 1.3f, 500),
getScaleAnimation(1.3f, 1.0f, 1700),
getScaleAnimation(0.4f, 1.3f, 2100),
getScaleAnimation(1.3f, 1.0f, 3400)
};
AnimationSet animationSet = addAnimationAr(animations);
view.startAnimation(animationSet);
Method:
public static AnimationSet addAnimationAr(Animation[] animations) {
AnimationSet animationSet = new AnimationSet(false);
long totalAnimationDuration = 0;
for (int i = 0; i < animations.length; i++) {
Animation a = animations[i];
a.setStartOffset(totalAnimationDuration);
totalAnimationDuration += a.getDuration();
animationSet.addAnimation(a);
}
return animationSet;
}

If you use code, you can call
Animation.setStartOffset()
to delay the second animation.
if you use xml you can android:ordering="sequentially" property to make the two animations perform sequentially.

For simple animations, you can achieve this by using the animate() and withEndAction() functions, like so:
ImageView img = findViewById(R.id.imageView);
img.animate().rotation(180).alpha(0).setDuration(3000).withEndAction(new Runnable() {
#Override
public void run() {
ImageView img = findViewById(R.id.imageView);
img.animate().rotation(0).alpha(1).setDuration(2000);
}
});

AnimationDrawable
Running such animation is pretty straightforward in Android. In fact, there is a class in Android API just for this specific task called AnimationDrwable. AnimationDrawable is a set of images together.
Step1: Create AnimationDrwable
Step2: Load Animation Drawable into ImageView
step3: start the animation
Step 1:
Create an XML and add all images like this.
<animation-list
xmlns:android="http://schemas.android.com/apk/res/android"
android:oneshot="true">
<item android:drawable="#drawable/cat_image_1" android:duration="200" />
<item android:drawable="#drawable/cat_image_2" android:duration="200" />
<item android:drawable="#drawable/cat_image_3" android:duration="200" />
</animation-list>
Step 2:
public void onCreate(Bundle savedInstanceState) {
//Step 2
ImageView myimage = (ImageView) findViewById(R.id.my_image);
myimage.setBackgroundResource(R.drawable.rocket_thrust);
//Step 3
AnimationDrawable catAnimation = (AnimationDrawable) rocketImage.getBackground();
catAnimation.start();
}
