The answer is yes, they do work, just probably not for what you expect - for instance, the description for `setFillAfter(boolean fillAfter)` says 

&gt; If fillAfter is true, the
&gt; transformation that this animation
&gt; performed will persist when it is
&gt; finished.

and when set to true it does do this. 

However, unintuitively an animation on Android does not actually animate the View itself, rather it animates a bitmap representation of the View.

The issue you are probably having is that after an animation the View goes back to being how it was before the animation - `setFillAfter` and `setFillBefore` cannot help you with that, because in that situation what you really want to do is set the properties of the View to be same as the animated representation (they are separate things), and `setFillAfter` and `setFillBefore` only apply to animation properties, not View properties.

The reason they exist is for chaining animations. Suppose you had a translate animation followed by a fade out. If you did not set `setFillAfter(true)` on the translate animation, then the View would translate, jump back to it&#39;s original position and then fade out. With `setFillAfter(true)` set on the translate animation, the view will move and then fade out at it&#39;s current spot.

What is the best way to bind a property to a control so that when the property value is changed, the control&#39;s bound property changes with it.

So if I have a property `FirstName` which I want to bind to a textbox&#39;s `txtFirstName` text value. So if I change `FirstName` to value &quot;Stack&quot; then the property `txtFirstName.Text` also changes to value &quot;Stack&quot;.

I know this may sound a stupid question but I&#39;ll appreciate the help.

As in the title of my question what are the methods `setFillBefore()` and `setFillAfter()` supposed to do? 

I was hoping `setFillAfter()` would make the change to the View permanent after an animation has completed, but this is incorrect?

I want to record human voice on my Android phone. I noticed that Android has two classes to do this: [AudioRecord][1] and [MediaRecorder][2]. Can someone tell me what&#39;s the difference between the two and what are appropriate use cases for each?

I want to be able to analyse human speech in real-time to measure amplitude, etc. Am I correct in understanding that AudioRecord is better suited for this task?

I noticed on the official Android [guide webpage for recording audio][3], they use MediaRecorder with no mention of AudioRecord.

I have a view which is used as an item in a `ListView`. In my custom adapter, I change the background of the view using `View.setBackgroundResource()` depending on the item&#39;s position in the list. (I have separate assets for the first and last items in the list.)

This sets the correct background image as expected, but it has the nasty side-effect that  all the padding I&#39;d set in the XML definition of the view is completely ignored.

(If I set the background drawable in the XML, and don&#39;t try to vary it at runtime in the adapter, the padding all works fine.)

How can I alter the background image, and retain the padding? Is this a bug?

**EDIT** it seems someone else has found the same problem here: https://stackoverflow.com/questions/2886140/does-change-the-background-change-the-padding-of-a-linear-layout

I have a fadeout animation in a view (which is inside a fragment), and everytime the animation happens, after it finishes the view redraws itself again. I found a work around doing `view.SetVisibility(View.GONE)` . But it doesn&#39;t wait for the animation to finish. I would like to execute this setVisibility code only after the animation has finished. What is the best way to do that?


End animation event android

I have an ImageView and I do a simple scale animation to it. Very standard code.

My scale_up.xml:

    &lt;set xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;&gt;
        &lt;scale android:fromXScale=&quot;1&quot;
               android:fromYScale=&quot;1&quot;
               android:toXScale=&quot;1.2&quot;
               android:toYScale=&quot;1.2&quot;
               android:duration=&quot;175&quot;/&gt;
    &lt;/set&gt;

My animation code:

    Animation a = AnimationUtils.loadAnimation(this, R.anim.scale_up);
    ((ImageView) findViewById(R.id.circle_image)).startAnimation(a);

The problem:

When the image scales it doesn&#39;t scale from the center, but from the top left corner. In other words, the scaled version of the image doesn&#39;t have the same point as the center, but it has the same top-left point. 
Here&#39;s an image that explains what I mean:

[![How the animation scales][1]][1]
[![How I want it][2]][2]

The first image is how the animation scales and the second image is how I want it to scale. It should keep the center point the same. 
I have tried setting up gravity on the image, on the container, aligning left or right, it always scales the same.

I&#39;m using RelativeLayout for the main screen and ImageView is located into another RelativeLayout, but I tried other layouts, no change.

Android image scale animation relative to center point

I want to swap two fragment in an activity via animation.Suppose PageA is for fragement A and left side on the screen and PageB is for fragment B i.e. on the right side of the screen. Now i want that when i click a button on pageA then PageA will move to the right side of the screen with some transition animation.

I tried the below code to replace the position
     
    FragmentManager fragmentManager = getSupportFragmentManager();
    FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
    fragmentTransaction.replace(R.id.container, new FragB());
    fragmentTransaction.commit();

   Looking for some clue.

   Thanks in advance.

swap fragment in an activity via animation

I push a fragment on the fragment stack using the following code:

    FragmentManager fragmentManager = getActivity().getSupportFragmentManager();
    FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
    fragmentTransaction.setCustomAnimations(R.anim.slide_in_right, R.anim.slide_out_right,
         R.anim.slide_in_left, R.anim.slide_out_left);
    fragmentTransaction.replace(getId(), newFragment);
    fragmentTransaction.addToBackStack(null);
    fragmentTransaction.commit();

This way, when the fragment stack is popped, e.g. by pressing the back button, a fragment pop animation is played. However, there are situations in which i would like to pop the fragment backstack without showing this animation, e.g. because I just returned from another activity and want to display the previous fragment at once, without animation.

An example navigation could look like this:

 - The user is on the start screen with the root fragment
 - He selects an item on the root fragment which then displays a new fragment to show details of that item. It does so using a fragment transaction that sets animations both for the push and the pop case (so when the user presses the back button, the transition is animated)
 - From this fragment he starts an activity which (for whatever reason) deletes the item that was just shown
 - When this activity finishes, I would like to return to the root fragment without showing the &quot;pop animation&quot; of the &quot;detail fragment&quot;

Is there a way to pop the fragment backstack without playing the specified pop animation?

I&#39;ve been looking through many google results / questions on here to determine how to show/hide a view via a vertical animation, but I can&#39;t seem to find one that&#39;s exactly right or not too vague.

I have a layout (undo bar) that&#39;s below another layout and above multiple other widgets; this undo bar should vertically slide open and slide closed, depending on the circumstances.

Currently all I do right now is set the view to be visible or gone.
