I have an image set in an ImageView and I want to animate it such a way that initially nothing is displayed on the screen and the the image enters from left and go towards right and finally fill the screen
In the code that i examine the image enters from left but doesn't fill the screen and left blank behind itself
ObjectAnimator transAnimation=
ObjectAnimator.ofFloat(imageView,"translationX",-100,100);
transAnimation.setDuration(3000);//set duration
transAnimation.start();//start animation
The code for animation that you posted seems to be working fine. The problem that you have is with imageview itself and the place it takes over your screen.
You said that your imageview is not taking full space and leaving blank space behind it,
so to fix it simply make your imageview width = match_parent. and if it still doesn't work then add scaleType=centerCrop
UPDATE:
Add this code to your onCreate()
imageView.post(new Runnable() {
#Override
public void run() {
startImageAnimation();
}
});
private void startImageAnimation() {
ObjectAnimator animation = ObjectAnimator.ofFloat(imageView, "translationX",-(imageView.getWidth()), 0);
animation.setDuration(1100);
animation.start();
}
step 1: create below left_to_right_anim file in anim directory of res
<?xml version="1.0" encoding="utf-8"?>
<set
xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="#android:anim/linear_interpolator"
android:fillAfter="true">
<translate
android:fromXDelta="0%p"
android:toXDelta="75%p"
android:duration="800" />
</set>
step 2:
//your image view
imageView = (ImageView) findViewById(R.id.img);
//name of animation from anim directory
animSlide = AnimationUtils.loadAnimation(getApplicationContext(),
R.anim.left_to_right_anim);
// Start the animation like this
imageView.startAnimation(animSlide);
step 3:
now calculate time of animation and when your imageview animate at right side stop it and set it into your screen.
to achieve this you can user handler when you start your animation.
Thread's run() method is used to get time of your animation.
thanks ;)
What about using TransistionManager?
val slideRight= Slide()
slideRight.slideEdge = Gravity.RIGHT
slideRight.mode = Slide.MODE_IN
slideRight.addTarget(logoImageView)
slideRight.duration = ANIMATION_DURATION
TransitionManager.beginDelayedTransition(parentContainer, slideRight)
logoImageView.visibility = VISIBLE
It is snippet from my working code in Kotlin
Also you can use TransitionSet to combine animations

I have 2 Images:
IMG_1:
IMG_1_PRESSED:
I display IMG_1 by default, but when I click on it, the image should change to IMG_1_PRESSED.
Here's a code snippet of the button itself, where be is an enum containing the correct drawables:
ImageButton ib = new ImageButton(this.context);
ib.setImageResource(be.getDrawable());
ib.setScaleType(ImageButton.ScaleType.CENTER_INSIDE);
ib.setBackgroundColor(Color.TRANSPARENT);
ib.setPadding(0, 0, 0, 0);
ib.setAdjustViewBounds(true);
ib.setMaxWidth(width);
ib.setMaxHeight(height);
setStrengthListener(ib, be);
And here is the setStrengthListener method:
private void setStrengthListener(final ImageButton ib, final ButtonEnum be){
ib.setOnTouchListener(new View.OnTouchListener() {
#SuppressLint("ClickableViewAccessibility")
#Override
public boolean onTouch(View v, MotionEvent event) {
switch(event.getAction()) {
case MotionEvent.ACTION_DOWN:
ib.setImageResource(be.getDrawablePressed());
return true;
case MotionEvent.ACTION_UP:
ib.setImageResource(be.getDrawable());
return true;
}
return false;
}
});
}
Now both images are 480x240 and width and height are set to device's width/3 and device's width/6 respectively (I want to display 3 images, hence the /3).
Here's the problem, if the button is pressed, I get this:
There's this little line under the pressed button... I've tried a lot to fix this but somehow that little line has made itself my greatest enemy today.
As an extra effort: the line doesn't show anymore if I set the original resource to IMG_1_PRESSED:
ImageButton ib = new ImageButton(this.context);
ib.setImageResource(be.getDrawablePressed());
ib.setScaleType(ImageButton.ScaleType.CENTER_INSIDE);
ib.setBackgroundColor(Color.TRANSPARENT);
ib.setPadding(0, 0, 0, 0);
....etc
But obviously I don't want to start with a pressed button.
So dear Android experts, what am I doing wrong here?
This is the simplest solution as i know,
Try this
create Xml inside your Drawable folder
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/btn_pressed_img"android:state_pressed="true" />
<item android:drawable="#drawable/btn_normal_image" />
</selector>
Then add this drawable file as background to your View
Example :
<ImageView
android:id="#+id/enter_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:maxHeight="100dip"
android:maxWidth="100dip"
android:layout_centerHorizontal="true"
android:layout_alignParentBottom="true"
android:background="#drawable/enter_btn" />
or in Java code
yourView.setImageResource(R.drawable.*drawablefile*);
You can use ImageButton also but ImageView would look better than ImageButton since it doesn't have button borders.
So after a hell of a lot of trial and error, I managed to get that grey line away. In the end it was very simple really, though I'm not completely sure why this fixed it:
The main layout:
LinearLayout ll = new LinearLayout(this);
ll.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));
ll.setOrientation(LinearLayout.HORIZONTAL);
ll.setGravity(Gravity.TOP);
The view creation (layout for imageview is unchanged):
ImageView iv = tbb.getTopBarButton(ButtonEnum.IMG_1);
LinearLayout iViewLayout = new LinearLayout(this);
iViewLayout.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
iViewLayout.setOrientation(LinearLayout.HORIZONTAL);
iViewLayout.addView(iv);
ll.addView(iViewLayout);
Adding a separate layout per imageview seemed to remove the grey line. Would love to know WHY this works though, but for future reference, at least I hope to help others.
I need to make an ImageView slide from left to right of the screen with a smooth animation (I want the ImageView to be visible during the transition) I tried with the following code:
Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
int width = size.x;
camion.animate()
.translationX(width)
.setDuration(2000)
.setInterpolator(new LinearInterpolator())
.setListener(new AnimatorListenerAdapter() {
#Override
public void onAnimationEnd(Animator animation) {
super.onAnimationEnd(animation);
//camion.setVisibility(View.GONE);
}
});
The ImageView moves but the animation is laggy and not smooth like I want to.
What am I doing wrong on the code?
Creating this kind of tween animation is simple. Just follow the steps,
Step 1
Create a directory anim inside the res directory and put this as slide.xml
<?xml version="1.0" encoding="utf-8"?>
<set
xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="#android:anim/linear_interpolator"
android:fillAfter="true">
<translate
android:fromXDelta="0%p"
android:toXDelta="75%p"
android:duration="800" />
</set>
You can obviously customize the animation by changing the two attributes fromXDelta and toXDelta. The %p refers to with respect to the parent which simply means that it will move the image 75% with respect to the parent.
Step 2
// Refer the ImageView like this
imageView = (ImageView) findViewById(R.id.img);
// Load the animation like this
animSlide = AnimationUtils.loadAnimation(getApplicationContext(),
R.anim.slide);
// Start the animation like this
imageView.startAnimation(animSlide);
You can also setInterpolator() and setListeners() if you want to. I haven't shown them here to keep it simple. If you need, just let me know.
NOTE
As you have mentioned repeatedly, that you are experiencing a laggy animation. I have tested this animation on 3 real devices and 2 emulators and the animation was buttery smooth on all of them. Tested on low end devices like Moto E to high end devices like Nexus 5 and Galaxy S6.
If you still have a lag running this code, then the test device must be the reason. The code is perfect.
UPDATE
I just checked on my Moto G running on Lollipop too, the animation is running smoothly. This is a very small and light-weight animation, and should never be laggy. If you are still getting a lag, then it must be the device you are testing, or some other piece of code on that Activity making the UI slow or unresponsive.
Try to check which one is applicable to you,
I have tested on a total of 6 devices now with no lag at all. So, you can be rest assured that your production app will not have any lag, it can be your device which is slow
If you are doing some heavy operations like accessing the file system, database, or any other heavy operation, it must be slowing down the UI thread and you are loosing frames. Try to use AsyncTask for these heavy operations
Try this. It will animate the imageview.
ImageView img_animation = (ImageView) findViewById(R.id.img_animation);
Display display = getWindowManager().getDefaultDisplay();
float width = display.getWidth();
TranslateAnimation animation = new TranslateAnimation(0, width - 50, 0, 0); // new TranslateAnimation(xFrom,xTo, yFrom,yTo)
animation.setDuration(1000); // animation duration
animation.setRepeatCount(5); // animation repeat count
animation.setRepeatMode(2); // repeat animation (left to right, right to
// left )
// animation.setFillAfter(true);
img_animation.startAnimation(animation); // start animation
TranslateAnimation animate = new TranslateAnimation(0, -view.getWidth(), 0, 0);
animate.setDuration(500);
animate.setFillAfter(true);
view.startAnimation(animate);
Hope this works for u

To Move imageview
from Right to Left Using #Aritra Roy Answer.
Use this code
<?xml version="1.0" encoding="utf-8"?>
<set
xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="#android:anim/linear_interpolator"
android:fillAfter="true">
<translate
android:fromXDelta="75%p"
android:toXDelta="0%p"
android:duration="100000" />
</set>
Now we have MotionLayout try to use that for very clean and smooth sliding animation.
I have the following xml:
<?xml version="1.0" encoding="utf-8"?>
<set
xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="#android:anim/accelerate_interpolator">
<translate
android:fromXDelta="0%p"
android:toXDelta="30%p"
android:duration="600">
</translate>
</set>
and this class:
switch_bg.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (!isChecked) {
Animation animation = android.view.animation.AnimationUtils
.loadAnimation(AppService.getAppContext(),
com.waze.R.anim.slide_to_right);
animation.setInterpolator(new AccelerateInterpolator());
animation.setFillAfter(true);
boxImage_left.startAnimation(animation);
AlphaAnimation alpha = new AlphaAnimation(1, 0);
alpha.setDuration(1000);
alpha.setInterpolator(new AccelerateInterpolator());
alpha.setFillAfter(true);
vImage_left.startAnimation(alpha);
} else {
Animation animation = android.view.animation.AnimationUtils
.loadAnimation(AppService.getAppContext(),
com.waze.R.anim.slide_to_left);
animation.setInterpolator(new AccelerateInterpolator());
animation.setFillAfter(true);
boxImage_left.startAnimation(animation);
AlphaAnimation alpha = new AlphaAnimation(0, 1);
alpha.setDuration(1000);
alpha.setInterpolator(new AccelerateInterpolator());
alpha.setFillAfter(true);
vImage_left.startAnimation(alpha);
}
TransitionDrawable transition = (TransitionDrawable) switch_bg
.getBackground();
transition.reverseTransition(TRANSITION_TIME);
isChecked = !isChecked;
}
});
}
when I move the box right-to-left it stays there after animation,
but after animation left-to-right it returns to origin position on the left.
How come?
I use alpha.setFillAfter(true); on both cases.
update
strangely if I cancel the setFillAfter for alpha animation,
the sliding transition stays OK at the end. How come? these are two different transition objects.
As I understand it you need only a single tween animation at a time on a view; you should be able to express the alpha animation in the xml too. This would solve your problem; should be reliable across all android versions (I'm not sure your current solution always looks right); and simplify the code.
I'm trying to do an animation that goes like this:
The context:
I have two EditText's I need that when you click over one, the another one come out from behind the first one. Here you have some pictures to get a image of what I want.
To do this obviously I need a TranslateAnimation in order to move the second EditText from behind the first one.
My approach:
The first thing that I could thought was in use a FrameLayout put the EditText one over another, and then in the onTouch event of the first one do a TranslateAnimation on the second one. The problem with this is that if I have the FrameLayout height in wrap_content then the animation will be invisible to the user. And if I change on runtime the height of the FrameLayout I will leave a void below the first EditText as you can see in this picture:
The second solution that I thought was add one AnimationListener to the TranslateAnimation and in the onAnimationStart method change the height of the FrameLayout. But the problem with this is that the height of the FrameLayout changes too abruptly. I want keep the animation smooth.
My question:
How can I get a smooth animation of the second EditText from behind the first one, changing the height of the FrameLayout as the second EditText moves down?
Thanks!
Update:
I changed the FrameLayout by a RelativeLayout I searched and there's no difference for this case. I tried scale this RelativeLayout that contains both of the EditText with an AnimationScale in order to display the animation smoothly, but didn't work. Here is my code:
protected void expanse() {
Log.d("Accordion", "expandAccordion");
//Translate the top of the second EditText to its bottom
TranslateAnimation translateSecond = new TranslateAnimation(second.getLeft(), second.getLeft(),
second.getTop(), second.getBottom());
translateSecond.setDuration(1000);
//Scale the relative layout to show the both of them
ScaleAnimation scaleContainer = new ScaleAnimation(container.getLeft(), container.getLeft(),
container.getTop(), second.getBottom());
scaleContainer.setDuration(1000);
//At the end of the scaling, change the height of the relative layout
scaleContainer.setAnimationListener(new AnimationListenerAdapter() {
#Override
public void onAnimationEnd(Animation animation) {
RelativeLayout.LayoutParams params = (LayoutParams) container.getLayoutParams();
params.height = second.getBottom();
container.setLayoutParams(params);
super.onAnimationEnd(animation);
}
});
container.startAnimation(scaleContainer);
second.startAnimation(translateSecond);
}
BTW I can guarantee that if I hardcode some large height like 350dp, the animation is displayed correctly.
UPDATE:
I tried moving both, the second EditText and the layout below. This is the code. BTW for another reasons I changed the ListView by a custom ViewPager, this doesn't change anything.
public class MainActivity extends FragmentActivity {
private EditText first;
private EditText second;
private HoboViewPager pager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
pager = (HoboViewPager) findViewById(R.id.pager);
pager.setPageTransformer(true, new RotationPageTransformer());
pager.setAdapter(new SampleAdapter(this, getSupportFragmentManager()));
first = (EditText) findViewById(R.id.location_search_field);
second = (EditText) findViewById(R.id.term_search_field);
first.setOnTouchListener(new OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
expanseSecondField();
return true;
}
});
}
protected void expanseSecondField() {
TranslateAnimation translateSecondField = new TranslateAnimation(second.getLeft(), second.getLeft(),
second.getTop(), second.getBottom());
translateSecondField.setFillAfter(true);
translateSecondField.setDuration(1000);
TranslateAnimation translateContainer = new TranslateAnimation(pager.getLeft(), pager.getLeft(),
pager.getTop(), pager.getTop() + second.getBottom());
translateContainer.setFillAfter(true);
translateContainer.setDuration(1000);
pager.startAnimation(translateContainer);
second.startAnimation(translateSecondField);
}
}
This didn't work because the TranslateAnimation of the container is executed immediately. The result is the same that when I was trying to change the size of the container at the end of the animation.
How use the 2nd option & try performing two translate animations in tandem: 1 on the EditText, then one on the FrameLayout? Give them both the same exact deltas and duration. This way, the FrameLayout will move down smoothly, then at the end of the animation, change the height of the FrameLayout.
Hope this helps :)
I am trying to make Settings in the app, specificly a ListPreference to be able to change the background animation of the app, but I can't do it, nothing changes if you choose option 1 or option 2... I followed a similar tutorial and tried to make it work for me, but nothing so far.
Here is the java
SharedPreferences backChooser = PreferenceManager.getDefaultSharedPreferences(getBaseContext());
String values = backChooser.getString("list", "1");
img = (ImageView) findViewById(R.id.imageView1);
img.setBackgroundResource(R.drawable.anim1);
animation = (AnimationDrawable) img.getDrawable();
animation.start();
if (values.contentEquals("1")) {
img.setBackgroundResource(R.drawable.anim1);
animation = (AnimationDrawable) img.getDrawable();
animation.start();
}
if (values.contentEquals("2")) {
img.setBackgroundResource(R.drawable.anim2);
animation = (AnimationDrawable) img.getDrawable();
animation.start();
}
and here is the xml of the preferences
<?xml version="1.0" encoding="utf-8"?>
<ListPreference
android:entries="#array/list"
android:entryValues="#array/listvalues"
android:key="list"
android:summary="This is a list to choose from"
android:title="List" />
This line of code
img.setBackgroundResource(R.drawable.anim1);
sets an ImageView's "Background".
Were as this code
img.getDrawable();
gets an ImageView's "Drawable" or the image on it, not the actual "Background" image.
Since you want to retrieve the image that you've once set as the BG of "img", this code
img.getBackground();
is the one that you need.
