<h3>And the list</h3>

<pre><code>ArrayList&lt;Student&gt; arraylist = new ArrayList&lt;Student&gt;();
</code></pre>

<h3>Code from Calling activity</h3>

<pre><code>Intent intent = new Intent(this, SecondActivity.class);

</code></pre>

blocks|key|3075671|text|首先，让列表的类实现可序列化的。|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|3075672|public+class+MyObject+implements+Serializable{}|code-block|syntax|javascript|3075673|然后你可以将列表转换为(Serializable)。如下所示：|3075674|List<MyObject>+list+=+new+ArrayList<>();
myIntent.putExtra("LIST",+(Serializable)+list);|3075675|要检索列表，请执行以下操作：|3075676|Intent+i+=+getIntent();
list+=+(List<MyObject>)+i.getSerializableExtra("LIST");|3075677|就这样。|3075678|entityMap^0|A|5|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|W|8|@$9|X|A|Y|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|Z|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|10|8|@]|D|@]|E|$]]|$1|M|3|N|5|H|7|11|8|@]|D|@]|E|$I|J]]|$1|O|3|P|5|6|7|12|8|@]|D|@]|E|$]]|$1|Q|3|R|5|H|7|13|8|@]|D|@]|E|$I|J]]|$1|S|3|T|5|6|7|14|8|@]|D|@]|E|$]]|$1|U|3|-4|5|6|7|15|8|@]|D|@]|E|$]]]|V|$]]

First, make the class of the list implement Serializable.
<pre><code>public class MyObject implements Serializable{}
</code></pre>
Then you can just cast the list to (Serializable). Like so:
<pre><code>List&lt;MyObject&gt; list = new ArrayList&lt;&gt;();
myIntent.putExtra(&quot;LIST&quot;, (Serializable) list);
</code></pre>
And to retrieve the list you do:
<pre><code>Intent i = getIntent();
list = (List&lt;MyObject&gt;) i.getSerializableExtra(&quot;LIST&quot;);
</code></pre>
That's it.

blocks|key|216664|text|有两种方法可以将对象数组列表或对象从一个活动发送到另一个活动：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|216665|216666|Parcelable|ordered-list-item|offset|length|216667|Searializable|216668|216669|entityMap|0|LINK|mutability|MUTABLE|url|https://guides.codepath.com/android/using-parcelable|1|https://medium.com/@kkunalandroid/serializable-in-android-with-example-38eb8b7334ea^0|0|0|0|A|0|0|0|D|1|0|0^^$0|@$1|2|3|4|5|6|7|U|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|V|8|@]|9|@]|A|$]]|$1|C|3|D|5|E|7|W|8|@]|9|@$F|X|G|Y|1|Z]]|A|$]]|$1|H|3|I|5|E|7|10|8|@]|9|@$F|11|G|12|1|13]]|A|$]]|$1|J|3|-4|5|6|7|14|8|@]|9|@]|A|$]]|$1|K|3|-4|5|6|7|15|8|@]|9|@]|A|$]]]|L|$M|$5|N|O|P|A|$Q|R]]|S|$5|N|O|P|A|$Q|T]]]]

there are 2 ways to send an arraylist of objects or an object from one activity to another:

</ol>

blocks|key|216691|text|您也可以使用Gson将列表转换为字符串，然后像这样传递它：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|216692|String+yourListAsString+=+new+Gson().toJson(yourList);
bundle.putString("data",yourListAsString);|code-block|syntax|javascript|216693|然后使用您的类作为类型来检索它：|216694|List<YourList>+listName+=+new+Gson().fromJson("data",+new+TypeToken<List<YourList>>(){}.getType());|216695|entityMap^0|6|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|$]]

You can also convert the list to a String using <code>Gson</code>, then pass it like so:
<pre><code>String yourListAsString = new Gson().toJson(yourList);
bundle.putString(&quot;data&quot;,yourListAsString);
</code></pre>
Then retrieve it back using your class as the type:
<pre><code>List&lt;YourList&gt; listName = new Gson().fromJson(&quot;data&quot;, new TypeToken&lt;List&lt;YourList&gt;&gt;(){}.getType());
</code></pre>

If there is someone who is looking for answer this is how i implemented it using Kotlin.
Parcelable object class

 override fun writeToParcel(parcel: Parcel?, int: Int) {

 override fun newArray(size: Int): Array&lt;CollectedMilk?&gt; {

}
</code></pre>
Then in Fragment
<pre><code>collectedMilkAdapter.onItemClick = { collectedMilk -&gt;
 Toast.makeText(

 bundle.putParcelableArrayList(&quot;collectedMilk&quot;, collectedMilkArrayList)

Then on another Activity my Detail Activity
Global Variable
<pre><code>private lateinit var collectedMilk: ArrayList&lt;CollectedMilk&gt;

In Function or OnCreate Activity
<pre><code>val bundle = intent.extras

Another alternative will be the use of Gson.
copy this extension to your code:
<pre><code>// will write a list of objects to intent
fun Intent.putExtra(name: String, objs: List&lt;*&gt;) = putExtra(name, Gson().toJson(objs))

// will read a list of objects from intent
inline fun &lt;reified T&gt; Intent.getObjListExtra(name: String): List&lt;T&gt;? {
 val lstStr = getStringExtra(name) ?: return null
 val lst = Gson().fromJson&lt;List&lt;T&gt;&gt;(lstStr, object: ParameterizedType {
 override fun getActualTypeArguments(): Array&lt;Type&gt; = arrayOf(T::class.java)
 override fun getRawType(): Type = List::class.java
 override fun getOwnerType(): Type = T::class.java
 })
 return lst
}
</code></pre>
and use them:
Activity 1:
<pre><code>startActivity(Intent(this, Activity2::class.java).also {
 val people = listOf(Person(&quot;Moishe&quot;), Person(&quot;Albert&quot;), Person(&quot;Lezly&quot;))
 it.putExtra(&quot;people&quot;, people)
 })
</code></pre>
Activity 2:
<pre><code>val people = intent.getObjExtra&lt;Person&gt;(&quot;Person&quot;)
</code></pre>
This solution aim to use Gson as the parser

Kotlin
First, make the class of the list implement Serializable.
<pre><code>class MyObject: Serializable{}
</code></pre>
Then you can just cast the list to (Serializable). Like so:
<pre><code>val list: List&lt;MyObject&gt; = mutableListOf&lt;MyObject&gt;();
myIntent.putExtra(&quot;LIST&quot;, list as Serializable);
</code></pre>
And to retrieve the list you do:
<pre><code>val mlist = intent.getSerializableExtra(&quot;LIST&quot;) as? List&lt;ModuleDataRow&gt;
</code></pre>
That's it.

I want to pass a list of objects from one activity from another activity. I have one class SharedBooking Below:

<pre><code>public class SharedBooking {
 public int account_id;
 public Double betrag;
 public Double betrag_effected;
 public int taxType;
 public int tax;
 public String postingText;
}
</code></pre>

Code from Calling activity:

<pre><code>public List&lt;SharedBooking&gt; SharedBookingList = new ArrayList&lt;SharedBooking&gt;();

public void goDivision(Context context, Double betrag, List&lt;SharedBooking&gt; bookingList) {
 final Intent intent = new Intent(context, Division.class); 
 intent.putExtra(Constants.BETRAG, betrag); 
 intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
 context.startActivity(intent); 
}
</code></pre>

COde on called activity:

<pre><code>Bundle extras = getIntent().getExtras();
if (extras != null) {
 amount = extras.getDouble(Constants.BETRAG,0);
}
</code></pre>

How can I send the list of SharedBooking from one activity and receive that on other activity?

Please suggest me any usable link or sample code.
