I think you have to remove <code>mAnimation.setFillAfter(true);</code> because this means that it will stay permanently where it stops. 

In order to return to the initial position, either you can make a complete animation set for both moving up and down, or make two separate and when the first finish, then start the second, although there is no reason to follow such an approach.

blocks|key|576856|text|您需要设置repeat属性|type|unstyled|depth|inlineStyleRanges|entityRanges|data|576857|android:repeatMode|576858|整型。动画到达动画末尾时的行为方式。android:repeatCount必须设置为正整数或"-1“，此属性才会生效。设置为"+reverse“可使动画在每次迭代时反转方向，或设置为"repeat”可使动画每次循环从头开始。|576859|Animation+a;

You need to set the repeat property

android:repeatMode

int. How an animation behaves when it reaches the end of the animation. android:repeatCount must be set to a positive integer or "-1" for this attribute to have an effect. Set to "reverse" to have the animation reverse direction with each iteration or "repeat" to have the animation loop from the beginning each time.

<pre><code>Animation a;
a.setRepeatMode(Animation.REVERSE);
</code></pre>

Modify your code according to this:

<pre><code> mScanner.setVisibility(View.VISIBLE);
 mAnimation = new TranslateAnimation(
 TranslateAnimation.ABSOLUTE, 0f,
 TranslateAnimation.ABSOLUTE, 0f,
 TranslateAnimation.RELATIVE_TO_PARENT, 0f,
 TranslateAnimation.RELATIVE_TO_PARENT, 1.0f);
 mAnimation.setDuration(10000);
 mAnimation.setRepeatCount(-1);
 mAnimation.setRepeatMode(Animation.REVERSE);
 mAnimation.setInterpolator(new LinearInterpolator());
 mScanner.setAnimation(mAnimation);
</code></pre>

And moreover use xml rather than image. Please see the below code and put it in your <code>ImageView</code> src.

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;shape xmlns:android="http://schemas.android.com/apk/res/android"
 android:shape="line"&gt;
 &lt;solid android:color="#0000FF"/&gt;
 &lt;size android:width="480dp"
 android:height="10dp"/&gt;
 &lt;corners android:radius="1dp"/&gt;
 &lt;stroke android:width="3dp"
 android:color="#000000"/&gt;
&lt;/shape&gt;
</code></pre>

I hope it will help you.

blocks|key|793148|text|首先，像这样定义一个anim+XML文件：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|793149|<set+xmlns:android="http://schemas.android.com/apk/res/android">

++++++++android:repeatMode="reverse"
++++++++android:toYDelta="2%25p"+/>
</set>|code-block|syntax|javascript|793150|其次，使用Kotlin应用它：|793151|val+anim+=+AnimationUtils.loadAnimation(
++++++++++++requireContext(),
++++++++++++R.anim.anim
++++++++)


++++++++binding.yourView.animation+=+anim|793152|entityMap^0|A|4|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@$9|R|A|S|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|T|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|U|8|@]|D|@]|E|$]]|$1|M|3|N|5|H|7|V|8|@]|D|@]|E|$I|J]]|$1|O|3|-4|5|6|7|W|8|@]|D|@]|E|$]]]|P|$]]

First, define an <code>anim</code> XML file like that:
 
<pre><code>&lt;set xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;&gt;
 &lt;translate
 android:duration=&quot;800&quot;
 android:fromYDelta=&quot;0%p&quot;
 android:repeatCount=&quot;infinite&quot;
 android:repeatMode=&quot;reverse&quot;
 android:toYDelta=&quot;2%p&quot; /&gt;
&lt;/set&gt;
</code></pre>
Second, apply it using Kotlin:
<pre><code>val anim = AnimationUtils.loadAnimation(
 requireContext(),
 R.anim.anim
 )


 binding.yourView.animation = anim
</code></pre>

I have successfully done one side animation using <code>Translate Animation</code> means the image goes from top to the bottom. Here is the code:

<pre><code>private ImageView mScanner;
private Animation mAnimation;

@Override
public void onCreate(Bundle savedInstanceState) 
{
 super.onCreate(savedInstanceState);
 setContentView(R.layout.main);

 mScanner = (ImageView)findViewById(R.id.Scanner);

 mAnimation = new TranslateAnimation(0, 0, 0, 500);
 mAnimation.setDuration(10000);
 mAnimation.setFillAfter(true);
 mAnimation.setRepeatCount(-1);
 mAnimation.setRepeatMode(Animation.REVERSE);
 mScanner.setAnimation(mAnimation);
 mScanner.setVisibility(View.VISIBLE);
}
</code></pre>

Now I want that when image reaches to the bottom of the screen, it should start moving back to the top. How can I do that?

Note: Done the reverse mode. Please see the code. But now problem is that, it leaves lines when moving from bottom to top. Like the attached image. How to remove this lines?

Kotlin

我已经成功地使用Translate Animation完成了单面动画，这意味着图像从上到下。代码如下：private ImageView mScanner;private Animation mAnimation;@Overridepublic void onCreate(Bundle savedInstanceSta...
