I want to have some sort of animation when user clicks an image. I tried adding Blink animation to texureView but it keeps blinking. Below is the code:
Animation animation;
mTextureView = (AutoFitTextureView)view.FindViewById(Resource.Id.texture);
animation = AnimationUtils.LoadAnimation(Activity,Resource.Animation.blink);
mTextureView.StartAnimation(animation);
<set xmlns:android="http://schemas.android.com/apk/res/android">
<alpha android:fromAlpha="0.0"
android:toAlpha="1.0"
android:interpolator="#android:anim/accelerate_interpolator"
android:duration="0"
android:repeatMode="reverse"
android:repeatCount="infinite"/>
</set>
I basically want a default click effect which occurs when you click an image by going to the camera app. Is there any way I can achieve this?

I want to make a Fade Out and In Animation every time I click a button.
I started to check only the fade out and on the first click it seems the Fade Out works just fine. But when I click again the animation fade from top to bottom, making it look bad and cut.
The Animation:
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<alpha android:fromAlpha="1.0"
android:toAlpha="0.0"
android:interpolator="#android:anim/accelerate_interpolator"
android:duration="1000" />
</set>
The Code:
Animation fadeOut = AnimationUtils.loadAnimation(myActivity.this, R.anim.fade_out);
LinearLayout myBackground=(LinearLayout)findViewById(R.id.myBackground);
myBackground.setAnimation(fadeOut);
What am I missing? Thanks!
Make anim in following folder ris->anim->fade_anim.xml
Add below xml
<alpha
android:duration="2000"
android:fromAlpha="1"
android:toAlpha="0.0"
android:repeatCount="infinite"/>
Got to java class
//make animation object
final Animation myAnim = AnimationUtils.loadAnimation(getContext(), R.anim.bounce_anim);
myAnim.setRepeatMode(Animation.INFINITE);
//get View on which on you want to apply animation I am applying on imageView
mLayout.findViewById(R.id.imageView).startAnimation(myAnim);
I am trying to start an animation AFTER 1 second. I have used the attribute "android:startOffset" in my XML file, but it does not work completely the way I expected. I was expecting the view to NOT EVEN BE DRAW in its initial position (that is, the position set in the attributes "fromXDelta" and "fromYDelta") before the offset I set has passed. Here is my XML:
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:ordering="sequentially"
android:shareInterpolator="false" >
<translate
android:duration="2000"
android:startOffset="1000"
android:fromXDelta="-70%p"
android:fromYDelta="0%p"
android:interpolator="#android:anim/linear_interpolator"
android:toXDelta="+0%p"
android:toYDelta="0%p" />
</set>
If I try to move my view using the above animation, the view is drawn IMMEDIATELY at the position -70% of the screen. Then the one second passes and then, as expected, the animation kicks in and starts to move the view. However, I DO NOT want the view to be drawn at all before that 1 second!. How can I achieve this?
Thank you in advance.
UPDATE
I am calling the above XML just after a startActivity call (the *R.anim.animation_coming_in* below), like this:
startActivity(new Intent(this, ThankYouActivity.class));
overridePendingTransition(R.anim.animation_coming_in, R.anim.animation_coming_out);
You could try using a pair of alpha animations with very short duration so that the view is hidden until it's needed. Something like this:
<set ...>
<alpha
android:fromAlpha="0.0"
android:toAlpha="0.0"
android:duration="1"
android:startOffset="0" />
<alpha
android:fromAlpha="0.0"
android:toAlpha="1.0"
android:duration="1"
android:startOffset="1000" />
<translate
...
/>
</set>
Alternatively, you could implement this set of animations in code. Doing so would enable you to use a Handler to start the animation after a delay so that the view is hidden until the animation starts.
Image this scenario, I have a bitmap travelling across the screen from left to right and a button which when pressed will call clearAnimation()
When this button is pressed, it calls clearAnimation() on the travelling bitmap but the bitmap stays in the position (somewhere between left and right) on the screen.
What I actually would like to happen is that when the button is pressed, the bitmap ends up at the end of the animation point (right of the screen)
Any idea how to achieve this please? Below is my animation code
questionAnimation = AnimationUtils.loadAnimation(QuestionActivity.this, R.anim.left_to_right);
questionWrapper.setBackgroundDrawable(getResources().getDrawable(R.drawable.imageview_rounded));
questionWrapper.startAnimation(questionAnimation);
i think what is happening to your animation is that its setFillAfter() is setted to true by default or either you have setted it to true before applying animation, through java or from xml so first you should set setFillAfter to false or you can directly change setFillEnabled to false like here in xml applied to set
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:fillAfter="false" >
<translate
android:duration="300"
android:fromYDelta="100%p"
android:toYDelta="0" />
<alpha
android:duration="300"
android:fromAlpha="0.0"
android:toAlpha="1.0" />
</set>
Or
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:fillEnabled="false" >
<translate
android:duration="300"
android:fromYDelta="100%p"
android:toYDelta="0" />
<alpha
android:duration="300"
android:fromAlpha="0.0"
android:toAlpha="1.0" />
</set>
hence in this case when animation ends or clears it won't retain views image (suspend your image in middle) so secondly you have to set the new place of your image i.e to the right of screen through code when you clear animation or animation ends up naturally, for that you have to place the actual view(ImageView) to new place (As this was being handled previously by FillAfter but due to its malfunctioning of suspending view on pressing clear animation you need to remove it so now you have to cover its functionality by urself) by setting properties of your ImageView like if it's in RelativeLayout then by setting property of AlignParentRight to true.
I want to have a View that initially is invisible and when I press a button, it becomes visible with a fade in animation. I'm using the AlphaAnimation for the fading effect. The problem is that if I make the view invisible the animation can't be seen.
Suppose you have an ImageView named imageView and an animation file your_fade_in_anim.xml inside your res\anim\ folder:
ImageView imageView = (ImageView) findViewById(R.id.imageView);
Animation fadeInAnimation = AnimationUtils.loadAnimation(this, R.anim.your_fade_in_anim);
// Now Set your animation
imageView.startAnimation(fadeInAnimation);
Your XML
<?xml version="1.0" encoding="UTF-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<alpha
android:fromAlpha="0.0"
android:toAlpha="1.0"
android:interpolator="#android:anim/accelerate_interpolator"
android:duration="[duration (in milliseconds)]"
android:repeatCount="infinite" />
</set>
Replace the brackets with your actual duration.
Provide an AnimationListener to the Animation and make the View visible as soon as the Animation starts.
http://developer.android.com/reference/android/view/animation/Animation.AnimationListener.html
Instead of the infinite repeat count and hiding/viewing your View, I suggest to just not repeat the animation and initially start with the alpha channel set to maximum. Then you can use:
<?xml version="1.0" encoding="UTF-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<alpha
android:fromAlpha="0.0"
android:toAlpha="1.0"
android:interpolator="#android:anim/accelerate_interpolator"
android:duration="[duration (in milliseconds)]"
android:repeatCount="0" />
</set>
And you're done. No need for a Listener, hiding or showing. Just as simple.
I'm trying to create an animation which will slide a textview out to the left and slide in again from the right. Essentially, this would be the same text effect used in the Stopwatch & Timer app (sportstracklive is the developer).
I can use either of these animation sets exclusive of the other and it works fine, does exactly what I want. But as soon as I try using them together, the TextView just blinks over the course about around 1 second. Removing the startOffset works as expected. Both animation sets run simultaneously.
Here's the XML:
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:fromXDelta="0%"
android:toXDelta="-25%"
android:fromYDelta="0%"
android:toYDelta="0%"
android:duration="#android:integer/config_shortAnimTime"
/>
<alpha
android:interpolator="#android:anim/decelerate_interpolator"
android:fromAlpha="1.0"
android:toAlpha="0.0"
android:duration="#android:integer/config_shortAnimTime"
/>
<set>
<translate
android:fromXDelta="25%"
android:toXDelta="0%"
android:fromYDelta="0%"
android:toYDelta="0%"
android:startOffset="#android:integer/config_shortAnimTime"
android:duration="#android:integer/config_shortAnimTime"
/>
<alpha
android:interpolator="#android:anim/decelerate_interpolator"
android:fromAlpha="0.0"
android:toAlpha="1.0"
android:startOffset="#android:integer/config_shortAnimTime"
android:duration="#android:integer/config_shortAnimTime"
/>
</set>
</set>
And here's the lengthy Java code that runs it:
AnimationSet mSlideRightToLeft =
(AnimationSet) AnimationUtils.loadAnimation(this, R.anim.slide_right_to_left);
mMyTextView.startAnimation(mSlideRightToLeft);
Justinl's comment is correct. I had the exact same problem a couple months ago. Remove the set tags around the other animations, and keep the startOffsets.
Next remove the animation set in your code and just do a normal load animation:
Animation a = AnimationUtils.loadAnimation(this, R.anim.slide_right_to_left);
mMyTextView.startAnimation(a);
Edit: Yea, it looks like Android simply doesn't like this setup when there are multiple animations at the same time. I think you might have to create separate files for each set of animations and then configure them via an AnimationSet inside your program.
