I'm looking for a way to pass, via bundle, an
ArrayList<Integer[]>
object to a Fragment (after activity is already created, so i can't use intent). By looking to android api, no method seems to do what i'm looking for. How can i do?
Sending activity:
final Intent intent = new Intent(this, SecondActivity.class);
Bundle extraBundle = new Bundle();
extraBundle.putIntegerArrayList("arraylist", [put array list here]);
intent.putExtras(extraBundle);
intent.setComponent(new ComponentName("com.myapp", "com.myapp.SecondActivity"));
startActivity(intent);
Receiving activity's onCreate():
final Intent intent = getIntent();
final Bundle extraBundle = intent.getExtras();
ArrayList<Integer> myIntegerArrayList = extraBundle.getIntegerArrayList("arraylist");
You can change "arraylist" to what you want in the setter and getter method calls, they just need to be the same.
I used Gson, convert to JSONArray and send via Bundle. But it may affects performance.
In First Activity
Intent activity = new Intent(MyActivity.this,NextActivity.class);
activity.putExtra("myArrayList", new Gson().toJson(myArrayList);
startActivity(activity);
In other activity..
Sting myArrayList;
Bundle extras = getIntent().getExtras();
if (extras != null) {
myArrayList= extras.getString("myArrayList");
Type listOfInteger = new TypeToken<List<Integer>>(){}.getType();
String s = new Gson().toJson(myArrayList, listOfInteger);
List<Integer> myList = new Gson().fromJson(s, listOfInteger);
}
int[] intarray = new int[] {4,5,6,7,8};
Bundle bundle = new Bundle();
bundle.putIntArray("integerarray", intarray);
Or an ArrayList with int arrays?
For that i think you should use Parcable.
Or you could try to send the individual intArrays via the bundle and put them together in the receiving Activity.
Like this:
int[] intarray1 = new int[] {4,5,6,7,8};
int[] intarray2 = new int[] {4,5,6,7,8};
int[] intarray3 = new int[] {4,5,6,7,8};
Bundle bundle = new Bundle();
bundle.putIntArray("INT_ARRAY1", intarray1);
bundle.putIntArray("INT_ARRAY2", intarray2);
bundle.putIntArray("INT_ARRAY3", intarray3);
Intent intent = new Intent(this,NewActivity.class)
intent.putExtras(bundle);
startActivity(intent)
Then in NewActivity.java you should create an array and get the bundle and fill the array with the received arrays.
you can pass the Array List of integers by using the method putIntegerArrayList
Here is the code snippet
ArrayList<Integer> values=new ArrayList<>();
values.add(1);
values.add(60);
values.add(75);
values.add(120);
Bundle extras = new Bundle();
extras.putIntegerArrayList(EXTRA_KEY,values);

how we can get the arraylist(both string and integer) from the resources xml
(5 answers)
Closed 4 years ago.
photo of the integer array in string.xml
I want to access this integer array into an arraylist in activity.
You can access this array as following:
int[] photos = context.getResources().getIntArray(R.array.photo);
You should use
Int[] intarray = getResources().getIntArray(R.string.photo);
I'm not sure if you are asking how to pass this to an Intent or how to convert it to ArrayList.
If it is the former:
1) Use the Bundle from the Intent:
Intent mIntent = new Intent(this, Example.class);
Bundle extras = mIntent.getExtras();
extras.putString(key, value);
2) Create a new Bundle
Intent mIntent = new Intent(this, Example.class);
Bundle mBundle = new Bundle();
mBundle.putString(key, value);
mIntent.putExtras(mBundle);
If you are asking about the latter try:
Resources r = getResources();
int[] p = r.getIntArray(R.array.photo);
Solution:
Create an Array-List of Integers:
public ArrayList<Integer> photoList = new ArrayList<>();
Then,
photoList = Arrays.asList(context.getResources().getIntArray(R.array.photo));
This will give you as ArrayList
Hope it helps.

Sending arrays with Intent.putExtra

how to send the array in intent in android studio?
i have two array list
Eve_id[];//here i had stored 5 diffrent values.
sc_id[];//here i had stored 5 diffrent values.
now i have to send these two array to next activity,i have used the code like this
1st activity`
Intent k = new Intent(context, Receiver.class);
k.putExtra("Event_id", Eve_id);
k.putExtra("schedule_id", sc_id);`
2nd activity
Bundle extras = getIntent().getExtras();
long[] event_id = extras.getLongArray("Event_id");
int[] schedule_id = extras.getIntArray("schedule_ids");
i dont know weather it is correct are not ,but i am not able to receive any data!
any one can suggest how to solve this!
You can use Bundle for That
Intent passArray = new Intent(MainActivity.this ,YourSecondClass.class);
Bundle bundle = new Bundle();
bundle.putStringArray("my_array", array);
startActivity(passArray , bundle);
passArray.putExtras(bundle);
startActivity(passArray);
Use ArrayList instead of array:
ArrayList<Long> eventIds = new ArrayList<>();
ArrayList<Integer> scheduleIds = new ArrayList<>();
fill them and put into bundle:
Bundle extras = new Bundle();
extras.putIntegerArrayList("schedule_ids",scheduleIds);
extrass.putLongArrayList("Event_id", eventIds);
Intent k = new Intent(context, Receiver.class);
k.putExtras(extras);
and then extract this values in Receiver activity:
Bundle extras = getIntent().getExtras();
ArrayList<Long> eventIds = extras.getLongArrayList("Event_id");
ArrayList<Integer> scheduleIds = extras.getIntegerArrayList("schedule_ids");
In my app, i need to send a Two dimensional Array and two more integer values form on Activity to Another with the help of Intent method.
This is done as ..
Intent i = new Intent(getApplicationContext(), ViewActivity.class);
Bundle postbundle = new Bundle();
String[][] X={{"abc"},{"def"}};
postbundle.putSerializable("data", X);
i.putExtra("A", postbundle);
i.putExtra("albumid", position);
i.putExtra("Bigcard",bigcard);
here am using .putSerializable method to place an array into bundle.
So to access these data in the receiver Activity am using
Bundle bundle = getIntent().getBundleExtra("A");
String[][] ABC=(String[][]) bundle.getSerializable("data");
Log.e("Array is",""+ABC);
but I got java.lang.NullPointerException error message..
Whith out use of " Static " declaration how can i get these values from bundle here (in the receiver Activity..)
Let me out pls from this ..
step-1:Write a seperate bean class and save into another file
public class MyBean implements Serializable{
String[][] data = null;
public void set2DArray(String[][] data){
this.data = data;
}
public String[][] get2DArray(){
return data;
}
}
step-2:In the calling activity
Intent intent = new Intent(this, Second.class);
String data[][] = new String[][] {{"1","kumar"},{"2","sona"},{"3","kora"},{"1","pavan"},{"2","kumar"},{"3","kora333"}};
MyBean bean = new MyBean();
bean.set2DArray(data);
Bundle b = new Bundle();
b.putSerializable("mybean", bean);
intent.putExtra("obj", b);
startActivity(intent);
step-3:In the caller activity
Bundle b = getIntent().getBundleExtra("obj");
MyBean dData = (MyBean) b.getSerializable("mybean");
String[][] str =dData.get2DArray();
Not a real answer, but a try:
what happens if You try:
Intent intent = getIntent();
int a = intent.getIntExtra("albumid"); //if Your value is an int, otherwise use String
//getStringExtra or whatever Your value is
I have two string Arrays, contactNames in the main Activity class, and address [] in the second activity class. when i click on the one of the names, it should show me the address details for that name. How should I create an intent for two string arrays in Android.
class ContactList
Intent i = new Intent (MainActivity.this, Details.class);
Bundle bundle = new Bundle ();
bundle.putStringArray("key", address);
i.putExtras(bundle);
startActivity(i);
}
class Details
Bundle b = this.getIntent().getExtras();
String array [] = b.getStringArray("key");
tvEmail.setText(array.toString());
}
thanks.
How should I create an intent for two string arrays in Android.
You can add another array (or any other data type) but you need to use a different key name. Example...
String[] array1;
String[] array2;
// Populate arrays here
Intent i = new Intent (MainActivity.this, Details.class);
Bundle bundle = new Bundle ();
bundle.putStringArray("key1", array1);
bundle.putStringArray("key2", array2);
i.putExtras(bundle);
startActivity(i);
Also note that you don't need to use a Bundle directly. You can use the Intent method putExtra(String name, String[] value). For example...
String[] array1;
String[] array2;
// Populate arrays here
Intent i = new Intent (MainActivity.this, Details.class);
i.putExtra("key1", array1);
i.putExtra("key2", array2);
startActivity(i);
How to pass a 2d String array to new activity???
and then in new activity, How can i retrieve the array??
You have to use:
String [][]str;
Intent summaryIntent = new Intent(this, Second.class);
Bundle b=new Bundle();
b.putSerializable("Array", str);
summaryIntent.putExtras(b);
startActivity(summaryIntent);
For Recieving the Array use:
Bundle b = getIntent().getExtras();
String[][] list_array = (String[][])b.getSerializable("Array");
Thanks
