I have a listview. I want to add one animation that is if I select one list item then it will be removed and rest of the items below that item will be shifted up with slide up animation. I have done this with linear layout by getting its child position but I am not able to understand how to slide up rest elements of listview. Please help
Below is my code for animation in dynamically created linear layout
plus.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Animation animation1 = AnimationUtils.loadAnimation(getActivity(), R.anim.move);
final Animation animation2 = AnimationUtils.loadAnimation(getActivity(), R.anim.moveup);
this is animation of that item on which we click
lay1.startAnimation(animation1);
this is code for animation rest child to slide up
final int i = lay1.getId() + 1;
final Handler handler = new Handler();
handler.postDelayed(new Runnable() {
#Override
public void run() {
//Do something after 100ms
try {
LinearLayout l = (LinearLayout) layoutall.getChildAt(i);
l.startAnimation(animation2);
layoutall.removeView(lay1);
} catch (Exception e) {
//connectToDatabase();
}
}
}, 600);
Updated Code
Thanks a lot. I was able to implement this functionality but problem is that I have used two animation in one listview but not able to implement first animation.
My code for list item to whom I want to swipe left while on click
viewHolder.accept.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
removeListItem(viewHolder.order_card_layout, position);
}
});
And code for animation is
protected void removeListItem(final View rowView, final int positon) {
// TODO Auto-generated method stub
final Animation animation = AnimationUtils.loadAnimation(rowView.getContext(), R.anim.move);
rowView.startAnimation(animation);
Animation.AnimationListener al = new Animation.AnimationListener() {
#Override
public void onAnimationEnd(Animation arg0) {
ViewHolder vh = (ViewHolder) rowView.getTag();
//vh.needInflate = true;
}
#Override public void onAnimationRepeat(Animation animation) {}
#Override public void onAnimationStart(Animation animation) {}
};
collapse(rowView, al);
}
but problem is that My first animation is not working that is slide right
final Animation animation = AnimationUtils.loadAnimation(rowView.getContext(), R.anim.move);
rowView.startAnimation(animation);
New Updated Code
I was able to implement this functionality but problem is that I have used two animations and want to do first animation on that item whom I click and another animation on all the list items below that clicked item.But my problem is that the item on which I clicked slide right and also it re appears and slide up with whole list but I want that the item on which i click will be slide right and rest will be slide up.
My code for list item to whom I want to swipe left while on click
viewHolder.accept.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
removeListItem(viewHolder.order_card_layout, position);
}

Here is code related to your requirement , Try this
https://github.com/paraches/ListViewCellDeleteAnimation
Download code and run it.
if you want to see demo than see this video,
http://www.youtube.com/watch?v=bOl5MIti7n0
Here is Code, where i am implementing both animation.
1) Slide from right while click on List-view Item-click.
2) while clicking on Delete Button, slide-up animation for remaining rows in list-view (which is already done in link i have given).
Copy below files to your anim folder.
1) fade_out.xml :
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="false">
<alpha
android:duration="700"
android:fromAlpha="1"
android:toAlpha="0" />
</set>
2) fade_in.xml :
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="false">
<alpha
android:duration="700"
android:fromAlpha="0"
android:toAlpha="1" />
</set>
3) slide_in_right.xml :
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="false">
<translate
android:duration="700"
android:fromXDelta="100%"
android:toXDelta="0%" />
</set>
4) slide_out_right.xml :
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="false">
<translate
android:duration="700"
android:fromXDelta="0%"
android:toXDelta="100%" />
</set>
Now add below methods and class to your activity,
//Animation
private void fadeOutView(View view) {
Animation fadeOut = AnimationUtils.loadAnimation(view.getContext(), R.anim.fade_out);
if (fadeOut != null) {
fadeOut.setAnimationListener(new ViewAnimationListener(view) {
#Override
protected void onAnimationStart(View view, Animation animation) {
}
#Override
protected void onAnimationEnd(View view, Animation animation) {
view.setVisibility(View.GONE);
}
});
view.startAnimation(fadeOut);
}
}
private void fadeInView(View view) {
Animation fadeIn = AnimationUtils.loadAnimation(view.getContext(), R.anim.fade_in);
if (fadeIn != null) {
fadeIn.setAnimationListener(new ViewAnimationListener(view) {
#Override
protected void onAnimationStart(View view, Animation animation) {
view.setVisibility(View.VISIBLE);
}
#Override
protected void onAnimationEnd(View view, Animation animation) {
}
});
view.startAnimation(fadeIn);
}
}
private void slideInView(View view) {
Animation slideIn = AnimationUtils.loadAnimation(view.getContext(), R.anim.slide_in_right);
if (slideIn != null) {
slideIn.setAnimationListener(new ViewAnimationListener(view) {
#Override
protected void onAnimationStart(View view, Animation animation) {
view.setVisibility(View.VISIBLE);
}
#Override
protected void onAnimationEnd(View view, Animation animation) {
}
});
view.startAnimation(slideIn);
}
}
private void slideOutView(View view) {
Animation slideOut = AnimationUtils.loadAnimation(view.getContext(), R.anim.slide_out_right);
if (slideOut != null) {
slideOut.setAnimationListener(new ViewAnimationListener(view) {
#Override
protected void onAnimationStart(View view, Animation animation) {
}
#Override
protected void onAnimationEnd(View view, Animation animation) {
view.setVisibility(View.GONE);
}
});
view.startAnimation(slideOut);
}
}
private abstract class ViewAnimationListener implements Animation.AnimationListener {
private final View view;
protected ViewAnimationListener(View view) {
this.view = view;
}
#Override
public void onAnimationStart(Animation animation) {
onAnimationStart(this.view, animation);
}
#Override
public void onAnimationEnd(Animation animation) {
onAnimationEnd(this.view, animation);
}
#Override
public void onAnimationRepeat(Animation animation) {
}
protected abstract void onAnimationStart(View view, Animation animation);
protected abstract void onAnimationEnd(View view, Animation animation);
}
Now, if you want to display animation on List Item Click then, give animation in Adapter class in which you have inflate raw_layout for listView.
5) raw_layout.xml :
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:id="#+id/linLayout">
<ImageButton
android:id="#+id/cell_trash_button"
android:layout_width="48dp"
android:layout_height="48dp"
android:src="#drawable/trash_can"
android:scaleType="fitXY" />
<TextView
android:id="#+id/cell_name_textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical|left"
android:layout_marginLeft="16dp"
android:layout_weight="1"
android:text="cell name" />
</LinearLayout>
6) finally Apply animation to your Parent Layout of raw_layout in getView() method of adapter onClick of Parent Layout.Here My parent layout for raw_layout is LinearLayout which have id named linLayout.
vh.linLayout.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
if (vh.linLayout.getVisibility() == View.VISIBLE) {
fadeOutView(vh.linLayout);
slideInView(vh.linLayout);
} else {
fadeInView(vh.linLayout);
slideOutView(vh.linLayout);
}
}
});
i have tried this and its working. So try this once!!

I have a horizontal recyclerView, When I first open the activity I want to make all the items in recyclerview scroll to the bottom (to the right in this case) and back to the top (to the left). Kinda like an animation. Scroll behavior should be visible to the user.
I tried to do it like:
Animation slideRight = AnimationUtils.loadAnimation(this, R.anim.slide_right);
Animation slideLeft = AnimationUtils.loadAnimation(this, R.anim.slide_left);
slideRight.setDuration(1000);
slideLeft.setDuration(1000);
slideRight.setAnimationListener(new Animation.AnimationListener() {
#Override
public void onAnimationStart(Animation animation) {
}
#Override
public void onAnimationEnd(Animation animation) {
recyclerView.startAnimation(slideLeft);
}
#Override
public void onAnimationRepeat(Animation animation) {
}
});
recyclerView.startAnimation(slideRight);
anim slide left:
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="false" >
<translate
android:duration="200"
android:fromXDelta="-100%"
android:fromYDelta="0%"
android:toXDelta="0%"
android:toYDelta="0%" />
</set>
anim slide right:
<translate
android:duration="200"
android:fromXDelta="100%"
android:fromYDelta="0%"
android:toXDelta="0%"
android:toYDelta="0%" />
it works however it just slides the recyclerview as a whole, I just want to scroll(slide) the items. How can I do this?
You can use scrollToPosition()
recyclerView.post(new Runnable() {
#Override
public void run() {
recyclerView.scrollToPosition(adapter.getItemCount() - 1);
// Here adapter.getItemCount()== child count
}
});
or smoothScrollToPosition()
recyclerView.post(new Runnable() {
#Override
public void run() {
recyclerView.smoothScrollToPosition(adapter.getItemCount()- 1);
}
});
To move up again, you need to call the above method with index 0. But first, you need to make sure that the RecyclerView is scrolled to last.
So, put a ScrollListener on RecyclerView to make sure the last item is visible.
Use this..
int top = 0;
recyclerView.smoothScrollToPosition(top); // for top
int bottom = recyclerView.getAdapter().getItemCount()-1;
recyclerView.smoothScrollToPosition(bottom);
if you need scroll item of recyclerview to CENTER of screen when for ex. expand your item - use this way:
in app/build.gradle - insert:
implementation 'com.andkulikov:transitionseverywhere:1.7.4'
when hadle click in onBindViewHolder of adapter - insert:
AutoTransition transitionPort = new AutoTransition();
transitionPort.setDuration(100);
transitionPort.addListener(new Transition.TransitionListener() {
#Override
public void onTransitionStart(#NonNull Transition transition) {
recyclerView.setEnabled(false);
recyclerView.setClickable(false);
}
#Override
public void onTransitionEnd(#NonNull Transition transition) {
recyclerView.post(() -> recyclerView.smoothScrollToPosition(position));
recyclerView.setEnabled(true);
recyclerView.setClickable(true);
}
#Override
public void onTransitionCancel(#NonNull Transition transition) {
recyclerView.setEnabled(true);
recyclerView.setClickable(true);
}
#Override
public void onTransitionPause(#NonNull Transition transition) {
}
#Override
public void onTransitionResume(#NonNull Transition transition) {
}
});
TransitionManager.beginDelayedTransition(recyclerView, transitionPort);
Not working after trying other things?
This excellent piece of code worked for me
private void scrollToBottom(final RecyclerView recyclerView) {
// scroll to last item to get the view of last item
final LinearLayoutManager layoutManager = (LinearLayoutManager) recyclerView.getLayoutManager();
final RecyclerView.Adapter adapter = recyclerView.getAdapter();
final int lastItemPosition = adapter.getItemCount() - 1;
layoutManager.scrollToPositionWithOffset(lastItemPosition, 0);
recyclerView.post(new Runnable() {
#Override
public void run() {
// then scroll to specific offset
View target = layoutManager.findViewByPosition(lastItemPosition);
if (target != null) {
int offset = recyclerView.getMeasuredHeight() - target.getMeasuredHeight();
layoutManager.scrollToPositionWithOffset(lastItemPosition, offset);
}
}
});
}
You can modifyline, if you want to jump to some other listitem & not last
final int lastItemPosition = adapter.getItemCount() - 1;

The animation starts when I clicked the ball.
It just moves down then to top then to the middle again.
However, the second onClick in the ball only works if I click in the middle, meaning the ball physically moves but the function's still in the middle.
How do I set its position according to the animation?
(The second click will cancel the animation)
onClick :
public void ballChange(View v)
{
isClicked = false;
if (ballstarted == false)
{
L1_animation = AnimationUtils.loadAnimation(this, R.anim.mercury_anim);
L1_Ball2.startAnimation(L1_animation);
ct = new CountDownTimer(4000, 1000)
{
#Override
public void onTick(long millisUntilFinished)
{
}
#Override
public void onFinish()
{
if (isClicked == false)
{
lifeline-=1;
if (lifeline == 0)
{
Toast.makeText(getApplicationContext(), "Gameover dude",
Toast.LENGTH_LONG).show();
heart.setText(""+lifeline);
GameOverDialog wp = new GameOverDialog(getApplicationContext());
wp.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
wp.show();
wp.setCancelable(false);
Mercury_L1.L1_Ball.clearAnimation();
Mercury_L1.L1_countDownTimer.cancel();
Mercury_L1.timerHasStarted = false;
Mercury_L1.isCancelled = true;
}
else
{
Toast.makeText(getApplicationContext(), String.valueOf(lifeline), Toast.LENGTH_SHORT).show();
heart.setText(""+lifeline);
minuslife.setVisibility(View.VISIBLE);
Handler handler = new Handler();
handler.postDelayed(new Runnable()
{
#Override
public void run()
{
minuslife.setVisibility(View.GONE);
}
}, 500);
Mercury_L1.this.v.vibrate(500);
}
}
}
}.start();
ballstarted = true;
Toast.makeText(getApplicationContext(), String.valueOf(ballstarted), Toast.LENGTH_SHORT).show();
}
else
{
L1_Ball2.clearAnimation();
ballstarted = false;
}
}
You are doing a view animation which only updates the place the ball is drawn and not its actual location. You should use a property animation like objectanimator. Below is some sample code for how to do that with XML.
public void doObjectAnimatorXML(){
AnimatorSet object = (AnimatorSet) AnimatorInflater.loadAnimator(getActivity(),R.animator.property_animator);
object.addListener(new AnimatorListenerAdapter(){
#Override
public void onAnimationEnd(Animator animation) {
simpleLock= false;
}
});
object.setInterpolator(new LinearInterpolator());
object.setTarget(mLittleChef); //mLittleChef is the view
object.start();
}
And the XML
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" android:ordering="sequentially" >
<objectAnimator
android:propertyName="x"
android:duration="1000"
android:valueTo="138"
android:valueType="floatType"/>
<objectAnimator
android:propertyName="x"
android:duration="1000"
android:valueTo="276"
android:valueType="floatType"/>
</set>
I simply want to use this working animation code I have in a more efficient manner. The code below works exactly as I want it to but I don't want to copy and paste this everywhere in the thirty places across several activities in which I'll be using this specific fadeout animation. How can I set up a class to do this? The primary problem is setting the view to invisible in onAnimationEnd.
final TextView ph = (TextView) findViewById(R.id.textPlaceholder);
final Animation fadeOut = new AlphaAnimation(1.0f, 0.0f);
fadeOut.setStartOffset(1000);
fadeOut.setDuration(500);
fadeOut.setAnimationListener(new AnimationListener() {
#Override
public void onAnimationEnd(Animation animation) {
ph.setVisibility(View.INVISIBLE);
}
#Override
public void onAnimationRepeat(Animation animation) {
// TODO Auto-generated method stub
}
#Override
public void onAnimationStart(Animation animation) {
// TODO Auto-generated method stub
}
});
ph.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
ph.startAnimation(fadeOut);
}
});
Create a helper class:
Class ClickToFadeOutAnimation
private View view;
public static void attachTo(View view) {
new FadeOutAnimation(View view);
}
public FadeOutAnimation(View view) {
this.view = view;
view.setOnCLickListsner(new OnClickListener() {
animate();
)
}
public void animate() {
Animation fadeOut = ...
.. rest of your animation code
}
}
And to use it:
TextView ph = (TextView) findViewById(R.id.textPlaceholder);
ClickToFadeOutAnimation.attachTo(ph);
Extend the AlphaAnimation class where you set the duration, offset and AnimationListener in the constructor.
I am willing to create a news bar in android application and I used the animation to move TextView from left to right and fill it each round with a new text from array of strings. I faced a lot of problems and I used more than 5 ways but each one has a bad behaviour. the main problem is that when the animation ends it refreshes the textView and it appears like flashing which is not a user-friendly behaviour.
Here is a code snippet:
TextView my_text;
Animation slideRight;
Animation slideLeft;
String [] text = {"TwoOneOneOneOneOneOneOneOneOneTwo","OneTwoTwoTwoTwoTwoTwoTwoTwoTwoTwoOne",
"OneThreeThreeThreeThreeThreeThreeThreeOne","OneFourFourFourFourFourFourFourOne",
"OneFiveFiveFiveFiveFiveFiveFiveOne","OneSixSixSixSixSixSixSixOne",
"OneSevenSevenSevenSevenSevenSevenSeveOne","OneEightEightEightEightEightEightEightOne",
"OneNineNineNineNineNineNineNineOne"};
int arr_length;
int count = 0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
arr_length = text.length;
slideRight = AnimationUtils.loadAnimation(this, android.R.anim.slide_out_right);
slideRight.setDuration(2000);
slideRight.setRepeatCount(Animation.INFINITE);
slideRight.setAnimationListener(slideRightListener);
slideLeft = AnimationUtils.loadAnimation(this, android.R.anim.slide_in_left);
slideLeft.setDuration(2000);
slideLeft.setAnimationListener(slideLeftListener);
my_text = (TextView) findViewById(R.id.textView1);
my_text.setVisibility(TextView.VISIBLE);
my_text.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(getApplicationContext(), my_text.getText(), Toast.LENGTH_SHORT).show();
}
});
slideLeft.setAnimationListener(slideLeftListener);
my_text.startAnimation(slideLeft);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
AnimationListener slideLeftListener = new AnimationListener() {
#Override
public void onAnimationStart(Animation animation) {
my_text.setVisibility(TextView.VISIBLE);
}
#Override
public void onAnimationRepeat(Animation animation) {
my_text.setVisibility(TextView.VISIBLE);
}
#Override
public void onAnimationEnd(Animation animation) {
my_text.setVisibility(TextView.VISIBLE);
my_text.startAnimation(slideRight);
}
};
AnimationListener slideRightListener = new AnimationListener() {
#Override
public void onAnimationStart(Animation animation) {
my_text.setVisibility(TextView.VISIBLE);
}
#Override
public void onAnimationRepeat(Animation animation) {
my_text.setVisibility(TextView.VISIBLE);
}
#Override
public void onAnimationEnd(Animation animation) {
my_text.setVisibility(TextView.VISIBLE);
if(count<arr_length)
{
my_text.setText(text[count]);
count+=1;
my_text.startAnimation(slideLeft);
}
else
{
count=0;
my_text.setText(text[count]);
my_text.startAnimation(slideLeft);
}
}
};
}
I think ViewFlipper is more suitable for you.
Try adding setFillAfter(true) as that might stop the "refresh" behavior at the end of the Animation.
As I commented on #Bill above I realized that the refresh issue related to Android version.
I have tested the same code above on devices with Android Ice-Cream-Sandwich and it didn't "refresh".
If there is any solution on non-ICS I will accept it.
I've got this link and I found it great to me and can be customized as my requirements.
It uses HorizonalSlideshow.
I want to make a layout animated through translation animation from screen's particular X Y position. and this is happening very correcty. now the problem starts when animations completes the layout again go to screen's top rihgt corner. i want the layout stay at the same position on which the animation ends.
AnimationListener animationListener = new AnimationListener() {
#Override
public void onAnimationEnd(Animation arg0) {
drawer_layout.setVisibility(View.VISIBLE);
}
#Override
public void onAnimationRepeat(Animation animation) {
// TODO Auto-generated method stub
}
#Override
public void onAnimationStart(Animation animation) {
drawer_layout.setVisibility(View.VISIBLE);
}
};
final Animation animTranslate = AnimationUtils.loadAnimation(this,
R.anim.top_to_bottom_in);
animTranslate.setAnimationListener(animationListener);
drawer_layout = (LinearLayout) findViewById(R.id.drawer_layout);
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// bitmapBackground = CaptureBackground();
faded_layout.setBackgroundColor(Color.parseColor("#50ffffff"));
// HandleDropAnimation(drawer_layout);
drawer_layout.startAnimation(animTranslate);
}
});
and this is my xml.
<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="1000"
android:fromYDelta="25%p"
android:toYDelta="50%p" />
Call
animTranslate.setFillAfter(true);
before you start the animation. According to java docs:
If fillAfter is true, the transformation that this animation performed will persist when it is finished.
use before animation starts
animTranslate.setFillAfter(true);
