Translation Animation not working

I tried to do a simple animation from bottom left corner to right center and then to center of the screen
Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
screenWidthPx = size.x;
screenHeightPx = size.y;
final TranslateAnimation slideFromRight = new TranslateAnimation(screenWidthPx, screenWidthPx/2, screenHeightPx, screenHeightPx);
slideFromRight.setInterpolator(new AccelerateDecelerateInterpolator());
slideFromRight.setStartOffset(300);
slideFromRight.setDuration(600);
slideFromRight.setAnimationListener(new Animation.AnimationListener() {
#Override
public void onAnimationStart(Animation animation) {
}
#Override
public void onAnimationEnd(Animation animation) {
TranslateAnimation titleIconSlideUp = new TranslateAnimation(0, screenWidthPx/2, screenHeightPx, screenHeightPx/2);
titleIconSlideUp.setInterpolator(new AccelerateDecelerateInterpolator());
titleIconSlideUp.setStartOffset(500);
titleIconSlideUp.setFillAfter(true);
titleIconSlideUp.setDuration(1000);
tvAnimView.startAnimation(titleIconSlideUp);
}
#Override
public void onAnimationRepeat(Animation animation) {
}
});
tvAnimView.startAnimation(slideFromRight);
the second animation inside onAnimationEnd is working fine. But don't know why first animation is not working fine. where my layout is simple
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/rl_root"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clipChildren="false"
android:clipToPadding="false"
tools:context="broadpeak.animationlearning.AnimTestActivity">
<TextView
android:id="#+id/tv_anim_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World"
android:textColor="#color/colorPrimaryDark"
android:textSize="24sp" />
</RelativeLayout>

You should start your animation using this line:
tvAnimView.startAnimation(slideFromRight);
Just put this piece of code in click listener or onCreate(), onResume() methods, according to your needs.

Animate visibility of a view from gone to visible with animation

I have a view that is invisible by default(Just for the first time).
Now I need to switch the visibility to VISIBLE with this animation:
if (myView.getVisibility() == View.INVISIBLE) {
myView.setVisibility(View.VISIBLE);
myView.animate().translationY(0);
}
(Like the SnackBar default animation)
But this isn't working. It will turn visible with default animation
Is there any simple way that I could achieve this?
Note
I'm animating my view to dismiss, like this:
myView.animate().translationY(myView.getHeight());

You can do this using XML animation.
Create a slide-up animation XML using set and alpha and put this XML into your resource anim folder.
slide_up.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
<translate
android:duration="500"
android:fromYDelta="100%"
android:toYDelta="0" />
</set>
USE:
Use AnimationUtils.loadAnimation() to load animation from XML and set and start animation using .startAnimation() method.
Here is an example:
ImageView imageView = (ImageView) findViewById(R.id.imageView);
// slide-up animation
Animation slideUp = AnimationUtils.loadAnimation(this, R.anim.slide_up);
if (imageView.getVisibility() == View.INVISIBLE) {
imageView.setVisibility(View.VISIBLE);
imageView.startAnimation(slideUp);
}
Hope this will help~

Add animations using ConstraintLayout
Just add below code above the views whose visibility is updated:
TransitionManager.beginDelayedTransition(constraintLayout)
Note:
ConstraintLayout will only perform animation on its direct children since it only knows when you change layout parameters and constraints on the children that it handles.
ConstraintLayout only animates layout related changes.
For more see this post https://robinhood.engineering/beautiful-animations-using-android-constraintlayout-eee5b72ecae3

This is the best way to animate views visibility :
private void viewGoneAnimator(final View view) {
view.animate()
.alpha(0f)
.setDuration(500)
.setListener(new AnimatorListenerAdapter() {
#Override
public void onAnimationEnd(Animator animation) {
view.setVisibility(View.GONE);
}
});
}
private void viewVisibleAnimator(final View view) {
view.animate()
.alpha(1f)
.setDuration(500)
.setListener(new AnimatorListenerAdapter() {
#Override
public void onAnimationEnd(Animator animation) {
view.setVisibility(View.VISIBLE);
}
});
}
And then call this method wherever you wanted to make a view visible or gone and give the intended view to methods as the parameter.

Just You need to add android:animateLayoutChanges="true" to your layout.
When I set visibility gone to linear_container, linear_bottom will animate from bottom to up and take place of "linear_container".
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:animateLayoutChanges="true"
android:orientation="vertical"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:id="#+id/layoutTop"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</android.support.design.widget.AppBarLayout>
<LinearLayout
android:id="#+id/linear_container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
</LinearLayout>
<LinearLayout
android:id="#+id/linear_bottom"
android:layout_width="match_parent"
android:layout_height="wrap_content"
</LinearLayout>
</LinearLayout>

Based on this answer:
with this methods, I can set the visibility of my view to VISIBLE with a slideUp animation(Like snackbar animation):
int getScreenHeight() {
DisplayMetrics displaymetrics = new DisplayMetrics();
activity.getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
return displaymetrics.heightPixels;
}
public void animateOnScreen(View view) {
final int screenHeight = getScreenHeight();
ObjectAnimator animator = ObjectAnimator.ofFloat(view, "y", screenHeight, (screenHeight * 0.8F));
animator.setInterpolator(new DecelerateInterpolator());
animator.start();
}
Then I can use it like this:
if (myView.getVisibility() == View.INVISIBLE) {
myView.setVisibility(View.VISIBLE);
animateOnScreen(myView);
}

Animate view in relative layout to align parent top

I have a relative layout (let's call it A), inside a scroll view, inside a relative layout (we will call this layout B)
What I'm trying to do is remove a child from A, insert it into B and align it to the parent top (right below the action bar).
I've been trying to animate this slide up, and back down to it's original position without any luck.
Any idea how can I perform this animation?

A very late reply, but here's how I managed this:
center_to_top_center.xml (located in res/anim/)
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:duration="1000"
android:fillAfter="true"
android:fromXDelta="0%p"
android:fromYDelta="00%p"
android:toXDelta="00%p"
android:toYDelta="-40%p" />
</set>
HomeActivity.java
public class HomeActivity extends FragmentActivity {
#InjectView(R.id.imageView2)
ImageView mImageView;
#Override
protected void onCreate(Bundle savedInstanceState) {
setContentView(R.layout.activity_home, false);
beginLogoAnimation();
}
private void beginLogoAnimation(){
Animation translateAnim= AnimationUtils.loadAnimation(getApplicationContext(),
R.anim.center_to_top_center);
translateAnim.setFillAfter(true);
translateAnim.setFillEnabled(true);
translateAnim.setFillBefore(false);
translateAnim.setAnimationListener(new Animation.AnimationListener() {
#Override
public void onAnimationStart(Animation animation) {
}
#Override
public void onAnimationEnd(Animation animation) {
}
#Override
public void onAnimationRepeat(Animation animation) {
}
});
mImageView.startAnimation(translateAnim);
}
}
activity_home.xml
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/imageView2"
android:layout_centerInParent="true"
android:layout_marginTop="15dp"
android:layout_centerHorizontal="true"
android:src="#drawable/logo"
/>

Since you are Animating Layout Changes Try adding this to your layout block:
android:animateLayoutChanges="true"

How to animate a slide in notification view that pushes the content view down

I have two views on the screen
one sits at the top of the screen and on sits directly below it
I need the green view to slide out the top - and make the blue view take up the entire screen as a result
this is what i am trying to do:
-- the problem is , when the animation is finished, the blue view just "jumps" up - and i want it to ease up with the disappearing green view, how do i do that?
slide_in_animation.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:duration="1000"
android:fromYDelta="-100%"

</set>
slide_out_animation.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:duration="1000"
android:fromYDelta="0%"
android:toYDelta="-100%" />
</set>
MainActivity.java
slideInAnimation = AnimationUtils.loadAnimation(mActivity, R.anim.slide_in_animation);
slideOutAnimation = AnimationUtils.loadAnimation(mActivity,R.anim.slide_out_animation);
slideInAnimation.setAnimationListener(new AnimationListener() {
#Override
public void onAnimationStart(Animation animation) {
mGreenView.setVisibility(View.VISIBLE);
}
#Override
public void onAnimationRepeat(Animation animation) {
// TODO Auto-generated method stub
}
#Override
public void onAnimationEnd(Animation animation) {
}
});
slideOutAnimation.setAnimationListener(new AnimationListener() {
#Override
public void onAnimationStart(Animation animation) {
}
#Override
public void onAnimationEnd(Animation animation) {
mGreenView.setVisibility(View.GONE);
}
#Override
public void onAnimationRepeat(Animation animation) {
// To change body of implemented methods use File | Settings
// | File Templates.
}
});

This worked for me
First you must import this library: http://nineoldandroids.com/
The import is done by importing existing android project into your workspace, afterwards right click your Poject -> Properties -> Android. Here you will see a library section, click the Add button and add the nineoldandroids library.
First off, here is the layout xml used for this to work:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/parentLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".MainActivity" >
<FrameLayout
android:id="#+id/frameLayout"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" >
<ListView
android:id="#+id/listView1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/transparent"
android:divider="#android:color/transparent"
android:fastScrollEnabled="false"
android:listSelector="#android:color/transparent"
android:scrollbars="vertical"
android:smoothScrollbar="true" />
<View
android:id="#+id/greenView"
android:layout_width="match_parent"
android:layout_height="150dp"
android:background="#ff00ff00"
android:alpha="0"/>
</FrameLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<Button
android:id="#+id/animate"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:onClick="clickHandler"
android:text="animate" />
<Button
android:id="#+id/close"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:onClick="clickHandler"
android:text="close" />
</LinearLayout>
Notice: Both the ListView and the green View could be layouts of any types with any kind of content.
And next a proof of concept Activity.
public class TestActivity extends Activity {
private View greenView;
private ListView listView;
private int greenHeight;
private boolean isShowingBox;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_test);
// The animated view
greenView = (View)findViewById(R.id.greenView);
listView = (ListView)findViewById(R.id.listView1);
// Instanciating an array list (you don't need to do this, you already have yours)
ArrayList<String> your_array_list = new ArrayList<String>();
your_array_list.add("1");
your_array_list.add("2");
your_array_list.add("3");
your_array_list.add("4");
your_array_list.add("5");
your_array_list.add("6");
your_array_list.add("7");
your_array_list.add("8");
your_array_list.add("9");
your_array_list.add("10");
your_array_list.add("11");
your_array_list.add("12");
your_array_list.add("13");
your_array_list.add("14");
your_array_list.add("15");
// This is the array adapter, it takes the context of the activity as a first // parameter, the type of list view as a second parameter and your array as a third parameter
ArrayAdapter<String> arrayAdapter =
new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1, your_array_list);
listView.setAdapter(arrayAdapter);
final LinearLayout layout = (LinearLayout)findViewById(R.id.parentLayout);
final ViewTreeObserver vto = layout.getViewTreeObserver();
vto.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
#Override
public void onGlobalLayout() {
if (Build.VERSION.SDK_INT < 16) {
layout.getViewTreeObserver().removeGlobalOnLayoutListener(this);
} else {
layout.getViewTreeObserver().removeOnGlobalLayoutListener(this);
}
greenHeight = greenView.getHeight();
}
});
}
public void clickHandler(View v) {
if (isShowingBox) {
isShowingBox = false;
slideOut(1500, 0);
} else {
isShowingBox = true;
slideIn(1500, 0);
}
}
private void slideIn(int duration, int delay) {
AnimatorSet set = new AnimatorSet();
set.playTogether(
// animate from off-screen in to screen
ObjectAnimator.ofFloat(greenView, "translationY", -greenHeight, 0),
ObjectAnimator.ofFloat(listView, "translationY", 0, greenHeight),
ObjectAnimator.ofFloat(greenView, "alpha", 0, 0.25f, 1)
// add other animations if you wish
);
set.setStartDelay(delay);
set.setDuration(duration).start();
}
private void slideOut(int duration, int delay) {
AnimatorSet set = new AnimatorSet();
set.playTogether(
// animate from on-screen and out
ObjectAnimator.ofFloat(greenView, "translationY", 0, -greenHeight),
ObjectAnimator.ofFloat(listView, "translationY", greenHeight, 0),
ObjectAnimator.ofFloat(greenView, "alpha", 1, 1, 1)
// add other animations if you wish
);
set.setStartDelay(delay);
set.setDuration(duration).start();
}
}
Important note: Remember to import the AnimatorSet and ObjectAnimator from nineoldandroids in your class and not the Android SDK ones!!!

One potential solution that makes a nice and fluid exit is using the weight attribute of LinearLayout with a ValueAnimator. Assuming you're using LinearLayout as your parent view for your green and blue blocks, your code would look something like this.
layout.xml
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<!--Let's assume this is the view you wish you disappear-->
<View
android:id="#+id/view1"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:orientation="vertical"/>
<View
android:id="#+id/view2"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="2"/>
</LinearLayout>
Now with this, in your code you can use the ValueAnimator as follows:
public class MainActivity extends Activity implements AnimatorUpdateListener
{
View view1;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
view1 = (View)findViewById(R.id.view1);
}
public void someAction()
{
//This is the important part, because it is FROM the first value TO
//the second. Notice that it must be a float type
ValueAnimator anim = ValueAnimator.ofFloat(1f, 0f);
anim.setDuration(200);
anim.addUpdateListener(this);
anim.start();
}
#Override
public void onAnimationUpdate(ValueAnimator animation)
{
view1.setLayoutParams(new LinearLayout.LayoutParams(0,
LayoutParams.MATCH_PARENT,
(Float) animation.getAnimatedValue()));
}
}
The ValueAnimator will automatically calculate the increments and execute them to get the smooth transition you want with the added benefit of keeping your view running.
You may also need to handle some strange UI occurrences as a result of shrinking the view (i.e., TextViews may act funny on the transition out), but I didn't run into too much trouble patching those up and keeping it neat.
Good luck! Hope this helps.

Use following code.
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:fillAfter="true">
<scale
android:duration="500"
android:fromXScale="1.0"
android:fromYScale="0.0"
android:interpolator="#android:anim/linear_interpolator"
android:toXScale="1.0"
android:toYScale="1.0" />
</set>

An easy way to make GONE animation work

I have a custom search panel, which is a part of main layout. Most of time the panel is hidden. I would like to add appearing/disappearing animation to the panel. Here is the simplified layout excerpt:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<RelativeLayout
android:id="#+id/layoutSearch"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:visibility="gone" >
<EditText
android:id="#+id/editSearch"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<<Other inner views to be animated>>
</RelativeLayout>
<<Other views, which should not be affected by the animation>>
</LinearLayout>
Try 1: I added animation resources and attach them to the #id/layoutSearch with this line in XML:
android:layoutAnimation="#anim/search_in_layout"
anim/search_in.xml:
<translate
xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="#android:anim/overshoot_interpolator"
android:fromYDelta="-100%p"
android:toYDelta="0"
android:duration="#android:integer/config_longAnimTime" />
anim/search_in_layout.xml:
<layoutAnimation
xmlns:android="http://schemas.android.com/apk/res/android"
android:animation="#anim/search_in" />
The animation works fine, but only for the panel appearing. The panel disappears in a moment without animation when I hide it with:
mSearchLayout.setVisibility(View.GONE);
Try 2: I guess the above solution does not work as the animation destination parameters match the current panel position. OK, I created two more animation resources: anim/search_out.xml and anim/search_out_layout.xml. The only differences are exchanged "fromYDelta" and "toYDelta" values and updated "android:animation" value. Then I load the resources in the code and set them to the #id/layoutSearch like this:
LayoutAnimationController controller =
AnimationUtils.loadLayoutAnimation(this, R.anim.search_out_layout);
mSearchLayout.setLayoutAnimation(controller);
The "out" animation triggered on calling of setLayoutAnimation(). After the animation the search panel returns to it original position on the screen it had before "out" animation. If I try to call mSearchLayout.setVisibility(View.GONE) just after setLayoutAnimation(), I see no animation, the panel disappears at once.
Try 3: I guess I need to create the animation in the code and then set a listener on it. Then I should call mSearchLayout.setVisibility(View.GONE) in the onAnimationEnd() handler to hide the panel after the animation played. I did not tried this yet. I think it's over complicated.
I guess I missed something important. Is there a way to implement GONE animation a bit easy?

To follow on to the answers above : here is how I solved this problem.
Please note that setting setFillBefore and setFillAfter in your animation will lead to the following bug! Issue 5272: View with visibility View.GONE still generates touch events

Try 3: I guess I need to create the animation in the code and then set a listener on it. Then I should call mSearchLayout.setVisibility(View.GONE) in the onAnimationEnd() handler to hide the panel after the animation played. I did not tried this yet. I think it's over complicated.
That's what you should do and actually that's not hard to achieve.
Sample code:
public class YourClass extends Foo implements AnimationListener {
//...
#Override
public void onAnimationEnd(Animation a) {
// Do stuff.
}
#Override
public void onAnimationRepeat(Animation a) {
}
#Override
public void onAnimationStart(Animation a) {
}
}

you need to call setFillAfter() of Animation Class to hold the animation after playing.
RelativeLayout layout = (RelativeLayout) findViewById(R.id.layoutSearch);
Animation a = AnimationUtils.loadAnimation(this, R.anim.push_down);
a=setFillAfter(true);
layout.setLayoutAnimation(new LayoutAnimationController(a));
layout.startLayoutAnimation();

Setting a View to GONE effectively removes it from the layout. Instead you should set it to INVISIBLE, and then GONE after the animation has completed if you need to.
