I want to show/hide a popupwindow using a expand/collapse animation from this answer.
I was able to use the animation by applying it to the popup view which is a view inside popupwindow. The problem I'm facing now is that when user touches outside popupwindow, popupwindow automatically dismisses and I cannot show collapse animation before dismissing the Popup.
Here is the code I have written:
View popupView = View.inflate(context,R.layout.popuplayout, null);
popup = new PopupWindow(popupView,ViewGroup.LayoutParams.MATCH_PARENT,ViewGroup.LayoutParams.WRAP_CONTENT);
popup.setAnimationStyle(0);
popup.setOutsideTouchable(true);
popup.setFocusable(true);
popup.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
popup.showAsDropDown(anchor, 0, 0);
popup.setBackgroundDrawable(null);
popupView.post(new Runnable() {
#Override
public void run() {
expand(popupView);
}
});
.
.
.
private void expand(final View v) {
final int targetHeight = ((View)v.getParent()).getHeight();
// Older versions of android (pre API 21) cancel animations for views with a height of 0.
v.getLayoutParams().height = 1;
v.setVisibility(View.VISIBLE);
Animation a = new Animation()
{
#Override
protected void applyTransformation(float interpolatedTime, Transformation t) {
v.getLayoutParams().height = interpolatedTime == 1
? LayoutParams.MATCH_PARENT
: (int)(targetHeight * interpolatedTime);
v.requestLayout();
}
#Override
public boolean willChangeBounds() {
return true;
}
};
a.setDuration(200);
v.startAnimation(a);
}
I was wondering whether there is a way to show an animation before dismissing popup on touching outside without xml style or implement the given animation using xml animations.
public class PopupWindowCustom extends PopupWindow{
public dismiss(){
View view = getCustomView();
expand(view);
super.dismiss();
}
private expand(View view){
//do some anim
}
}
This is how you should do it,
1)Create Two Different set of animations.
say, popup_show.xml and popup_hide.xml and add it to your anim folder which you have to create inside res folder.
2)Now inside values folder create a xml called styles.xml and add these animations to it like this,
<style name="Animation">
<item name="android:windowEnterAnimation">#anim/popup_show</item>
<item name="android:windowExitAnimation">#anim/popup_hide</item>
</style>
3)Now set this style to your PopupWindow animation,
popup.setAnimationStyle(R.style.Animation);
Now it automatically detects Window Enter and Exit and provides with the required animation.
according to Andro Selva.

On the android material design principles page, one of the examples shows a FAB expanding into a new full screen. (Under "Full Screen")
http://www.google.com/design/spec/components/buttons-floating-action-button.html#buttons-floating-action-button-transitions
I've tried to implement the same effect in my app, but with little success.
I managed to create a FAB that expands into a view using this code as reference: https://gist.github.com/chris95x8/882b5c5d0aa2096236ba.
It worked, but I was wondering whether I could apply the same effect to an activity transition. I've tried looking it up and playing with it myself but could not find anything that might work.
I know I could make the FAB expand into a Fragment and not a whole new activity, but I'm not sure if that's what being done, and whether that's optimal or not.
And so my question is, is there a way to implement the fab-expanding reveal effect as an activity transition, or is it supposed to just reveal a new fragment?
I am developing an app which expands a FloatingActionButton into a new Activity. I'm not sure that if you like my implementation, but please see pictures at first:
So the first picture shows MainActivity and the last one shows SecondActivity, which is "expanded" from FAB.
Now, I want to mention that I'm not actually expanding a FAB into a new Activity but I can let user feel that the new page is expanded from that FAB, and I think that's enough for both developers and users.
Here's implementation:
Preparation:
A FloatingActionButton of course,
Visit https://github.com/kyze8439690/RevealLayout and import this library to your project. It is used to play reveal animation. It has a custom BakedBezierInterpolator to control reveal animation and make it material-styled.
Steps:
create activity_main.xml like this:
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!--Your main content here-->
<RevealLayout
android:id="#+id/reveal_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:visibility="invisible">
<View
android:id="#+id/reveal_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:visibility="invisible"/>
</RevealLayout>
</FrameLayout>
find Views:
mRevealLayout = (RevealLayout) findViewById(R.id.reveal_layout);
mRevealView = findViewById(R.id.reveal_view);
expand when user clicks FAB:
mFab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mFab.setClickable(false); // Avoid naughty guys clicking FAB again and again...
int[] location = new int[2];
mFab.getLocationOnScreen(location);
location[0] += mFab.getWidth() / 2;
location[1] += mFab.getHeight() / 2;
final Intent intent = new Intent(MainActivity.this, SecondActivity.class);
mRevealView.setVisibility(View.VISIBLE);
mRevealLayout.setVisibility(View.VISIBLE);
mRevealLayout.show(location[0], location[1]); // Expand from center of FAB. Actually, it just plays reveal animation.
mFab.postDelayed(new Runnable() {
#Override
public void run() {
startActivity(intent);
/**
* Without using R.anim.hold, the screen will flash because of transition
* of Activities.
*/
overridePendingTransition(0, R.anim.hold);
}
}, 600); // 600 is default duration of reveal animation in RevealLayout
mFab.postDelayed(new Runnable() {
#Override
public void run() {
mFab.setClickable(true);
mRevealLayout.setVisibility(View.INVISIBLE);
mViewToReveal.setVisibility(View.INVISIBLE);
}
}, 960); // Or some numbers larger than 600.
}
});
And here is hold.xml in res/anim:
<set
xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="false">
<translate
android:duration="960" <!-- Enough-large time is OK -->
android:fromXDelta="0%"
android:fromYDelta="0%"
android:toXDelta="0%"
android:toYDelta="0%"/>
</set>
That's all.
Improvements:
RevealLayout has a bug(plays rectangular instead of circular reveal animation) for devices under API 17(Android 4.2), you can add these lines in constructor of it:
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN_MR2) {
setLayerType(View.LAYER_TYPE_SOFTWARE, null);
}
If your SecondActivity contains complicated contents, a simple View used as reveal_view in the layout.xml isn't enough/perfect. You can include the second layout inside the RevealLayout reveal_layout. It seems wasteful and hard to control if the second layout won't appear same at every time. But for me, it will. So you can make other improvements if you should.
If you want to implement totally same animation shown in Material Design Guide, you can set layout_height of the RevealLayout into a specific number instead of match_parent. After expanding animation ends(or some time after the animation plays, which should make the whole process of animation smoothly), then you can animate translationY. The important point is, just cheat users visually by controlling animation duration.
Finally, this is my own experience/attempt and I'm a beginner in developing Android apps. If there are any mistakes/further improvements, please leave comments/edit my answer. Thank you.
I made a custom activity, based on this question Circular reveal transition for new activity , that handle the CircularRevealAnimation and his reverse effect when the activity finish:
public class RevealActivity extends AppCompatActivity {
private View revealView;
public static final String REVEAL_X="REVEAL_X";
public static final String REVEAL_Y="REVEAL_Y";
public void showRevealEffect(Bundle savedInstanceState, final View rootView) {
revealView=rootView;
if (savedInstanceState == null && Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
rootView.setVisibility(View.INVISIBLE);
ViewTreeObserver viewTreeObserver = rootView.getViewTreeObserver();
if(viewTreeObserver.isAlive()) {
viewTreeObserver.addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
#Override
public void onGlobalLayout() {
circularRevealActivity(rootView);
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN) {
rootView.getViewTreeObserver().removeGlobalOnLayoutListener(this);
} else {
rootView.getViewTreeObserver().removeOnGlobalLayoutListener(this);
}
}
});
}
}
}
#TargetApi(Build.VERSION_CODES.LOLLIPOP)
private void circularRevealActivity(View rootView) {
int cx = getIntent().getIntExtra(REVEAL_X, 0);
int cy = getIntent().getIntExtra(REVEAL_Y, 0);
float finalRadius = Math.max(rootView.getWidth(), rootView.getHeight());
// create the animator for this view (the start radius is zero)
Animator circularReveal = ViewAnimationUtils.createCircularReveal(rootView, cx, cy, 0, finalRadius);
circularReveal.setDuration(400);
// make the view visible and start the animation
rootView.setVisibility(View.VISIBLE);
circularReveal.start();
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home: onBackPressed();break;
return super.onOptionsItemSelected(item);
}
}
#Override
public void onBackPressed() {
destroyActivity(revealView);
}
private void destroyActivity(View rootView) {
if(Build.VERSION.SDK_INT>=Build.VERSION_CODES.LOLLIPOP)
destroyCircularRevealActivity(rootView);
else
finish();
}
#TargetApi(Build.VERSION_CODES.LOLLIPOP)
private void destroyCircularRevealActivity(final View rootView) {
int cx = getIntent().getIntExtra(REVEAL_X, 0);
int cy = getIntent().getIntExtra(REVEAL_Y, 0);
float finalRadius = Math.max(rootView.getWidth(), rootView.getHeight());
// create the animator for this view (the start radius is zero)
Animator circularReveal = ViewAnimationUtils.createCircularReveal(rootView, cx, cy, finalRadius, 0);
circularReveal.setDuration(400);
circularReveal.addListener(new Animator.AnimatorListener() {
#Override
public void onAnimationStart(Animator animator) {
}
#Override
public void onAnimationEnd(Animator animator) {
rootView.setVisibility(View.INVISIBLE);
finishAfterTransition();
}
#Override
public void onAnimationCancel(Animator animator) {
}
#Override
public void onAnimationRepeat(Animator animator) {
}
});
// make the view visible and start the animation
rootView.setVisibility(View.VISIBLE);
circularReveal.start();
}
}
You can extend this with your own activity and call in your onCreate the method 'showRevealEffect' like this:
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.your_activity_layout);
//your code
View root= findViewById(R.id.your_root_id);
showRevealEffect(savedInstanceState, root);
}
You also have to use a transparent theme like this one:
<style name="Theme.Transparent" parent="Theme.AppCompat.Light.NoActionBar">
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowBackground">#android:color/transparent</item>
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
<item name="colorControlNormal">#android:color/white</item>
</style>
In the end, to launch this activity you should pass via extra the coordinates where the animation should start:
int[] location = new int[2];
fab.getLocationOnScreen(location);
Intent intent = new Intent(this, YourRevealActivity.class);
intent.putExtra(SearchActivity.REVEAL_X, location[0]);
intent.putExtra(SearchActivity.REVEAL_Y, location[1]);
startActivity(intent);
you can use this lib [https://github.com/sergiocasero/RevealFAB][1]
[1]: https://github.com/sergiocasero/RevealFAB 3rd party its easy and simple to use
Add to your layout
<RelativeLayout...>
<android.support.design.widget.CoordinatorLayout...>
<!-- YOUR CONTENT -->
</android.support.design.widget.CoordinatorLayout>
<com.sergiocasero.revealfab.RevealFAB
android:id="#+id/reveal_fab"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:fab_color="#color/colorAccent"
app:fab_icon="#drawable/ic_add_white_24dp"
app:reveal_color="#color/colorAccent" />
</RelativeLayout>
Important: This component goes above your content. You can use Coordinator, LinearLayout... or another Relative layout if you want :)
As you can see, you have 3 custom attributes for customizing colors and icon
Setting information about intent:
revealFAB = (RevealFAB) findViewById(R.id.reveal_fab);
Intent intent = new Intent(MainActivity.this, DetailActivity.class);
revealFAB.setIntent(intent);
revealFAB.setOnClickListener(new RevealFAB.OnClickListener() {
#Override
public void onClick(RevealFAB button, View v) {
button.startActivityWithAnimation();
}
});
Don't forget call onResume() method!
#Override
protected void onResume() {
super.onResume();
revealFAB.onResume();
}
Someone investigated the implementation of transition between activities from Plaid. Her example were published via https://github.com/hujiaweibujidao/FabDialogMorph.
Briefly speaking, she transits two activities with:
The FAB as the shared element.
The layout in the target activity with the same android:transitionName as the FAB.
To smooth the animation, MorphDrawable (extended from Drawable) and MorphTransition (extended from ChangeBounds) are implemented and applied.
In android 5.0 i am trying to work with circular reveal animation
Problem
When i click on button to start reveal animation, on first click animation doesn't start
Second Click onwards it works normally
My Code
public class MainActivity extends ActionBarActivity {
Animator a;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final View cardType = findViewById(R.id.cardtype);
cardType.setVisibility(View.GONE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
a = ViewAnimationUtils.createCircularReveal(cardType,
cardType.getWidth(),
cardType.getHeight(),
0,
cardType.getHeight() * 2)
.setDuration(2500);
a.addListener(new AnimatorListenerAdapter() {
#Override
public void onAnimationStart(Animator animation) {
super.onAnimationStart(animation);
cardType.setVisibility(View.VISIBLE);
}
});
a.addListener(new AnimatorListenerAdapter() {
#Override
public void onAnimationEnd(Animator animation) {
super.onAnimationEnd(animation);
cardType.setVisibility(View.GONE);
}
});
findViewById(R.id.icon_first_activity).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
a.start();
}
});
}
}}
I haven't tried your code, but I think you have a small ordering problem. I think you just need to set the cardType visible before you start the animation.
Edited to add:
... and you should be setting your button View.INVISIBLE, not View.GONE.
Here: This code works.
Edited once more to add:
Yes. Your problem is that you set the view GONE initially. That means it has 0 size. Then you use cardType.getHeight and cardType.getWidth as reveal coordinates. They are 0. You are going to want to set the view INVISIBLE, initially, and then use width/2 and height/2 as the center of the reveal.
Basically what others answers say, it's correct, but the problem is if you want visibility GONE (because your layout requires it GONE!) you have to set visibility INVISIBLE in the xml with height 0dp (and/or width 0dp as well) and programmatically set the correct LayoutParams even inside the click event it will work. For example my code:
...
expandButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//To not have empty scroll, the container is INVISIBLE with 0dp height.
//Otherwise the Reveal effect will not work at the first click.
//Here I set the parameters programmatically.
viewContainer.setLayoutParams(new LinearLayout.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT));
if (viewContainer.getVisibility() == View.VISIBLE) {
expandButton.animate().rotation(0f).setDuration(duration).start();
Utils.unReveal(viewContainer, 0, 0);
} else {
expandButton.animate().rotation(180f).setDuration(duration).start();
Utils.reveal(viewContainer, viewContainer.getWidth(), 0);
}
}
});
...
#TargetApi(VERSION_CODES.LOLLIPOP)
public static void reveal(final View view, int cx, int cy) {
if (!hasLollipop()) {
view.setVisibility(View.VISIBLE);
return;
}
//Get the final radius for the clipping circle
int finalRadius = Math.max(view.getWidth(), view.getHeight());
//Create the animator for this view (the start radius is zero)
Animator animator =
ViewAnimationUtils.createCircularReveal(view, cx, cy, 0, finalRadius);
//Make the view VISIBLE and start the animation
view.setVisibility(View.VISIBLE);
animator.start();
}
#TargetApi(VERSION_CODES.LOLLIPOP)
public static void unReveal(final View view, int cx, int cy) {
if (!hasLollipop()) {
view.setVisibility(View.GONE);
return;
}
//Get the initial radius for the clipping circle
int initialRadius = view.getWidth();
//Create the animation (the final radius is zero)
Animator animator =
ViewAnimationUtils.createCircularReveal(view, cx, cy, initialRadius, 0);
//Make the view GONE when the animation is done
animator.addListener(new AnimatorListenerAdapter() {
#Override
public void onAnimationEnd(Animator animation) {
super.onAnimationEnd(animation);
view.setVisibility(View.GONE);
}
});
//Start the animation
animator.start();
}
If you set only GONE in the xml, the first time will never work because height/width/x/y/etc.. are 0. Also, if you just set INVISIBLE before the call to the animation it will not work as well, but if you start with visibility INVISIBLE it will initialize the layout params.
what i did is, Like i have two view with same height,As we now visibility gone returns 0 {height and width} than i am giving visible view height every time and its work for me.
The solution is don't get values directly into code
Either put the animation code on click and the values outside onclick
or get the values from other activity
By values i mean cardType.getWidth() and cardType.getHeight()
Without involving layoutParams, is there another way to resize, collapse or expand a view? I saw that animations in some vieos of the new Material Design and in the new Android Dialer App. Google said Material can change shape, size, rotation, color, etc. easyly ... but I can't find anything.
Is there backwards compatibility?
Until now in order to resize, collapse or expand a view we had to work with layoutParams like this for example:
public static void collapse(final View v) {
final int initialHeight = v.getMeasuredHeight();
Animation a = new Animation()
{
#Override
protected void applyTransformation(float interpolatedTime, Transformation t) {
if(interpolatedTime == 1){
v.setVisibility(View.GONE);
}else{
v.getLayoutParams().height = initialHeight - (int)(initialHeight * interpolatedTime);
v.requestLayout();
}
}
#Override
public boolean willChangeBounds() {
return true;
}
};
a.setDuration((int)(initialHeight / v.getContext().getResources().getDisplayMetrics().density));
v.startAnimation(a);
}
Here is an example of what I want from the new Google Android Dialer App:
I think ViewPropertyAnimator is what you want.
check this link http://developer.android.com/guide/topics/graphics/prop-animation.html#view-prop-animator
Here is an example:
view.animate().scaleY(endHeight/initialHeight).start()
this is the same animation that you did in your code
when I click on button then an animation goes to left to right and right to left only for menu section layout and according to this animation the width of other layout (head of family should be expand or collapse..
my problem is that the animation for menu layout is working properly but the width of other layout not to collapse or expand simultaneously ,how can i do this.
my code is this
if(flagmenu)
{
//menu layout set animation
lpmenu.startAnimation(animationFallout);
Thread t=new Thread(new Runnable() {
public void run() {
try {
Thread.sleep(2500);
runOnUiThread(new Runnable() {
public void run() {
lpmenu.setVisibility(View.GONE);
}
});
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
t.start();
// lpmenu.setVisibility(View.GONE);
flagmenu = false;
}
else
{
lpmenu.startAnimation(animationFalling);
lpmenu.setVisibility(View.VISIBLE);
flagmenu = true;
}
Use this animation code here v is view group mean layout interpolatedTime of animation work fine for me . if code for collapse if u want expend then use + sine
Animation a = new Animation() {
#Override
protected void applyTransformation(float interpolatedTime,
Transformation t) {
if (interpolatedTime == 1) {
v.setVisibility(View.GONE);
} else {
v.getLayoutParams().width= initialwidth
- (int) (initialwidth * interpolatedTime);
// replace - to + for expend
v.requestLayout();
}
}
#Override
public boolean willChangeBounds() {
return true;
}
};
First, I would suggest you to use ObjectAnimators to achieve this instead of Animations, since Animation does not actually change the View's position. Then, in order to perform simultaneous animations with Animators you may use AnimatorSet class (playTogether method). If you need to support old Android versions there is a NineOldAndroids library which backports Animators. Another way (without animators) is to use AnimationSet (again you should add Animations for each view you want to move) class and implement AnimationListener changing the Layoutparams of your views (in order to update layout)
I have a Custom Listview with a lot of text in it.. I'd like that when I click on the the ListView other text will appear under the clicked row.. I managed to do this set the TextView to GONE in the custom_row.xml and then in the ClickListener set it to VISIBLE.. But this is too glitching and so I'd like to make a toggle animation like JQUERY's blind show...
How can I make this with an animation in Android ?
You can create your own Animation and change height of item, like:
public class ExpandAnimation extends Animation {
...
#Override
protected void applyTransformation(float interpolatedTime, Transformation t) {
super.applyTransformation(interpolatedTime, t);
if (interpolatedTime < 1.0f) {
viewLayoutParams.height = heightStart +
(int) (( heightEnd - heightStart) * interpolatedTime);
animatedView.requestLayout();
}
}
}
And set this animation on item when it's clicked.
Use a ValueAnimator to change the height of ListView from 0 to final height.
You can find a very good example in this tutorial
The code would be as follows:
ValueAnimator animator = ValueAnimator.ofInt(intialHeight, finalHeight);
animator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
#Override
public void onAnimationUpdate(ValueAnimator v) {
int value = (Integer) v.getAnimatedValue(); // get the most recent value calculated by the ValueAnimator
ViewGroup.LayoutParams lp = yourLayout.getLayoutParams(); // get the height of your ListView
lp.height = value; //change the height
mLinearLayout.setLayoutParams(layoutParams); //update it to the view
}
animator.start(); //start the animation
