I'm trying to get the result of intent between 2 activities but something is wrong because I always get a resultCode = 0 in initial activity:
Code inside CarsFragment.kt
private fun startAddCarActivity() {
val intent = Intent(context, AddCarActivity::class.java)
startActivityForResult(intent, 1)
}
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
// ALWAYS GET requestCode = 1, resultCode = 0 and data = null !!
}
AddCarActivity.kt:
private fun startCarsNavigationActivity() {
intent.putExtra("car", car)
setResult(1, intent)
finish()
}
Problem:
I always get requestCode = 1, resultCode = 0 and data = null in CarsFragment.kt
Where is the problem ?
Result code of 0 means RESULT_CANCELED. This can happen if the Activity you are launching is launched into a different task, or if the user presses the BACK key, or if the launched Activity decides to return RESULT_CANCELED.

Hi I am creating a SideActivity to gather some results and pass them back to Main Activity. However, the two strings value from the putextra are NULL rather than the string "20" and the jamSize "medium". Is there a way of passing the data properly?
Here in my Main Activity I have a setOnClickListener and a onActivityResult function.
jamButton.setOnClickListener {
var intent = Intent(this#MainActivity, SideActivity::class.java)
intent.putExtra("jamName", "raspberry")
intent.putExtra("jamPrice", "12.00")
startActivityForResult(intent, 1) // passing request code value 1
}
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
if(resultCode == RESULT_OK) {
val jamPrice:String = intent.getStringExtra("jamPrice").toString()
val jamSize:String = intent.getStringExtra("jamSize").toString()
val newJam = DataModel("Jam", "$jamSize", "$jamPrice")
list.add(0, newJam)
jamAdapter.notifyItemInserted(0)
}
}
Here is my Second Activity
completeBtn.setOnClickListener {
val jamPrice: String = textView2.text.toString()
val jamSize: String = textView3.text.toString()
val intent = Intent(this#SideActivity, MainActivity::class.java)
intent.putExtra("jamPrice", "20.00")
intent.putExtra("jamSize", jamSize)
setResult(Activity.RESULT_OK, intent)
finish()
}
In your onActivityResult don't use this :
val jamPrice:String = intent.getStringExtra("jamPrice").toString()
because the intent variable is the Intent of the activity instead use :
val jamPrice: String = data?.getStringExtra("jamPrice").toString()
Halllo, my BarcodeActivity is called by startActivityForResult through my PCActivity. The value of the scanned barcode should then be returned back to the PCActivity and inserted in a text field there. Unfortunately, I do not get a value back. However, the app does not crash either. Here is my code.
PCActivity:
sn_mb.setDrawableRightTouch {
val intent = Intent(this#PCActivity, BarcodeActivity::class.java)
startActivityForResult(intent, 1)
}
[...]
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
if (requestCode == 1 && resultCode == Activity.RESULT_OK && data != null) {
val returnedSN = intent.getStringExtra("return_sn")
sn_mb.setText(returnedSN)
} else {
sn_mb.setText("FEHLER!")
}
}
BarcodeActivity
saveBtn.setOnClickListener {
val sn = editTextBarcode.text.toString()
sn.toString()
if (sn!= "") {
val returnIntent:Intent = Intent()
returnIntent.putExtra("return_sn", sn)
setResult(Activity.RESULT_OK, returnIntent)
finish()
} else {
Toast.makeText(
applicationContext,
"Das ist keine gültige Seriennummer",
Toast.LENGTH_SHORT
).show()
}
}
I hope someone can explain or help me with this problem. Thank you very much.
You are extracting your data from the wrong place.
Replace
val returnedSN = intent.getStringExtra("return_sn")
with
val returnedSN = data.getStringExtra("return_sn")
The problem is you are not passing the scanned bar code value (sn) to the intent(returnIntent) in your BarCodeActivity.
First make sure sn is String since you want to pass a StringExtra, therefore:
val sn = editTextBarcode.text.toString()
And then pass sn to your return intent:
returnIntent.putExtra("return_sn", sn)
Notice that in your code you are passing integer 1 instead of sn.
EDIT:
One more minor fix to your code, didn't notice it:
val returnIntent:Intent = getIntent()
Notice that it's getIntent() instead of Intent()
I am trying to get data from one activity in other. But data always null.
val res = Intent()
res.putExtra("uri", imageUri)
setResult(Activity.RESULT_OK, res)
finish()
In the second activity I always get data as null. What is the problem? (imageUri is not null when I put it).
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
if(resultCode == Activity.RESULT_OK){
//data == null, WHY???
}
}
I think you need to define the intent with the current context and target class.
val intent = Intent(this#HomeActivity,ProfileActivity::class.java) // define you activity in which you want to go
intent.putExtra("Username","John Doe")
startActivity(intent)
Although everything work as intended and I get results from the Places API, the onActivityResult callback is never called when the user selects a result. What happens is that the result appears in the search textview and the Autocomplete activity doesn't exit. I have to press back for it to close.
// Set the fields to specify which types of place data to return.
val fields = Arrays.asList(Place.Field.ID, Place.Field.NAME)
// Start the autocomplete intent.
val intent: Intent = Autocomplete.IntentBuilder(
AutocompleteActivityMode.OVERLAY, fields
).setTypeFilter(TypeFilter.ADDRESS).
setCountry("DE")
.build(requireContext())
startActivityForResult(intent, AUTOCOMPLETE_REQUEST_CODE)
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
if(data!=null) {
var status: Status = getStatusFromIntent(data)
//var place: Place = getPlaceFromIntent(data)
}
super.onActivityResult(requestCode, resultCode, data)
}
Do you run method startActivityForResult inside Fragment? Check this out: onActivityResult is not being called in Fragment
You have to override onActivityResult in Activity which contains your fragment.
// In your activity
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
}
This will call your fragment's onActivityResult()
Ensure you're using the latest version of Place client SDK Places 2.1.0
. I don't see any reason in your code that causes the behavior you've addressed. Just use the below implementation and try.
private fun pickNewPlace() {
if (!Places.isInitialized()) {
Places.initialize(context!!, getString(R.string.google_service_api_key))
}
// Set the fields to specify which types of place data to return.
val fields = listOf(Place.Field.ID, Place.Field.NAME)
// Start the autocomplete intent.
val intent = Autocomplete.IntentBuilder(
AutocompleteActivityMode.OVERLAY, fields
).setTypeFilter(TypeFilter.ADDRESS).setCountry("DE").build(context!!)
startActivityForResult(intent, REQUEST_CODE_DEFAULT)
}
onActivityResult result handling
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
if (requestCode == REQUEST_CODE_DEFAULT) {
if (resultCode == RESULT_OK) {
// Get relevent info from place object
val place = Autocomplete.getPlaceFromIntent(data!!)
} else if (resultCode == AutocompleteActivity.RESULT_ERROR) {
val status = Autocomplete.getStatusFromIntent(data!!)
showAlertMessage(status.statusMessage ?: getString(R.string.something_went_wrong))
}
}
}
Here's my startActivityForResult():
val initialPosition = frame.tag as Int
val currentPosition = constraint.indexOfChild(frame)
Log.d(TAG, "initial position: $initialPosition") // prints initial position: 2
Log.d(TAG, "current position: $currentPosition") // prints current position: 2
val galleryIntent = Intent().apply {
type = "image/*"
action = Intent.ACTION_PICK
putExtra("initialPosition", initialPosition)
putExtra("currentPosition", currentPosition)
setResult(5)
}
startActivityForResult(Intent.createChooser(galleryIntent, "Pick image"), PICK_IMAGE_REQUEST_CODE)
However, I'm unable to retrieve the data here:
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
if (resultCode == Activity.RESULT_OK){
Log.d(TAG, "ResultCode: $resultCode SUCCESS") // prints -1 SUCCESS
}
when (requestCode){
PICK_IMAGE_REQUEST_CODE -> {
Log.d(TAG, "${data?.getIntExtra("initialPosition", 0)}") // prints 0
Log.d(TAG, "${data?.extras?.getInt("initialPosition")}") // prints 0
Log.d(TAG, "${data?.extras?.getInt("currentPosition")}") // prints 0
}
}
super.onActivityResult(requestCode, resultCode, data)
}
Any idea why?
setResult() will not set galleryIntent's result code. The one that will set that result is the activity that you picked during Intent.ACTION_PICK.
Assuming you picked the system image picker. It will return RESULT_OK(which is -1) if you select an image, and return RESULT_CANCELED(which is 0) if you backpress.
Note that you cannot change what other activity returns for resultCode if you use an Implicit Intent, which is what you just did.
