I must be doing something very silly, but even after a whole day, I cant call onActivityResult on MainActivity from another activity.
In my AuxActivity, I have
adapter.setOnItemClickListener(new CityListAdapter.ClickListener() {
#Override
public void onItemClick(View v, int position) {
City city =adapter.getCityAtPosition(position);
// Toast.makeText(getApplicationContext(),
// city.getCity()+"\n"+city.getLatitude()+"\n"+city.getLongitude(),
// Toast.LENGTH_LONG).show();
Double Lat = city.getLatitude();
Double Long = city.getLongitude();
Intent mainIntent = new Intent(getApplicationContext(), MainActivity.class);
mainIntent.putExtra("Lat", Lat);
mainIntent.putExtra("Long", Long);
mainIntent.putExtra("DbResultCode", Db_ACTIVITY_REQUEST_CODE);
startActivityForResult(mainIntent, Db_ACTIVITY_REQUEST_CODE);
finish();
}
});
In MainActivity, I am doing
// Inside onCreate
// Check Intent from Db
Intent intent = getIntent();
if (intent != null) {
Lat = intent.getDoubleExtra("Lat", 0.0);
Long = intent.getDoubleExtra("Long", 0.0);
DbResultStat = intent.getIntExtra("DbResultCode", 0);
}
I am getting values of Lat and Long properly here. But, then,
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Toast.makeText(this, ""+requestCode, Toast.LENGTH_LONG).show();
if (requestCode == DbActivity.Db_ACTIVITY_REQUEST_CODE){
if (resultCode==RESULT_OK){
setupViewPager();
}
}
This part is never called. I am still learning android, using the codelabs. So, anything new is giving me a lot of headache.
What I am doing wrong here?
Try these two steps:-
1)Pass Context of Main Activity instead of Application:
Intent mainIntent = new Intent(getApplicationContext(), MainActivity.class);
to:
Intent mainIntent = new Intent(this, MainActivity.class);
Then Run
2)Remove Super from override method of onActivityResult:
super.onActivityResult(requestCode, resultCode, data);
Then Run
Hope it Helps

I am trying to launch an activity after a user has selected a photo. I was trying to do this:
uploadImageButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent selectImageIntent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
selectImageIntent.setType("image/*");
startActivityForResult(selectImageIntent, 1);
Intent goToActivityIntent = new Intent(view.getContext(), SendPhotoChangeActivity.class);
goToActivityIntent.putExtra("email", email);
goToActivityIntent.putExtra("donorEmail", donorEmail);
goToActivityIntent.putExtra("orderId", orderId);
goToActivityIntent.putExtra("uriString", uriString);
view.getContext().startActivity(goToActivityIntent);
}
});
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == Activity.RESULT_OK && data != null) {
uriString = data.getData().toString();
}
}
But I realised that with this code, the code for launching the activity (SendPhotoChangeActivity) executes before the user selects the image, crashing the app because the uriString variable is null.
I tried simply copy/pasting the code into onActivityResult(), but the view variable (in view.getContext()) was, of course, not recognized in onActivityResult().
I am thinking of simply replacing view.getContext() by getApplicationContext() in onActivityResult(). Is this the right thing to do? If not, please tell me how I can start an activity in onActivityResult().
If you are in Activity then you can just use this as Context
Intent goToActivityIntent = new Intent(this, SendPhotoChangeActivity.class);
If you are in a Fragment then you can obtain Context by calling getContext()
Intent goToActivityIntent = new Intent(getContext(), SendPhotoChangeActivity.class);
And use that code inside onActivityResult() as you were trying to.
set an integer code for the act of selecting a picture like REQUEST_CODE_TAKE_PICTURE so you know that has happened, this works ok in Kotlin, I assume that works as well with java:
if (requestCode == REQUEST_CODE_TAKE_PICTURE && resultCode == Activity.RESULT_OK) {
Intent goToActivityIntent = new Intent(view.getContext(),SendPhotoChangeActivity.class);
goToActivityIntent.putExtra("email", email);
goToActivityIntent.putExtra("donorEmail", donorEmail);
goToActivityIntent.putExtra("orderId", orderId);
goToActivityIntent.putExtra("uriString", uriString);
view.getContext().startActivity(goToActivityIntent);
if (data == null) {
//Display an error
println("error accuered at onActivityResult ")
return
}
Have you tried this simpler one:
uploadImageButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent selectImageIntent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
selectImageIntent.setType("image/*");
startActivityForResult(selectImageIntent, 1);
}
});
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == Activity.RESULT_OK && data != null) {
uriString = data.getData().toString();
Intent goToActivityIntent = new Intent(view.getContext(), SendPhotoChangeActivity.class);
goToActivityIntent.putExtra("email", email);
goToActivityIntent.putExtra("donorEmail", donorEmail);
goToActivityIntent.putExtra("orderId", orderId);
goToActivityIntent.putExtra("uriString", uriString);
startActivity(goToActivityIntent);
}
}
Just call
startActivity(goToActivityIntent);
to call the activity.
This assumes you are calling it from your activity or fragment. If this doesn't meet your requirements, let me know. There are other ways to implement this.
I know there are several questions about this, but I don't found a solution for my problem.
I have ActivityA which extends AppCompatActivity. It starts an ActivityB
Activity A
Intent intent = new Intent(this, ActivityB.class);
intent.putExtra("data", data);
startActivityForResult(intent, 1);
....
#Override
protected void onActivityResult(int requestCode, int result, Intent intent) {
super.onActivityResult(requestCode, result, intent);
if (requestCode != 1) { // check code
return;
}
if (intent == null) { // HERE INTENT IS NULL
return;
}
}
Activity B
// code called when an asynctask is done
Intent i = new Intent();
i.putExtra("dataone", "test");
i.putExtra("datatwo", objet);
setResult(RESULT_OK, i);
finish();
I don't understand why intent is null in onActivityResult() method.
Two things. I would refactor your code like the following:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
if (requestCode == 1) {
if (resultCode == RESULT_OK) {
// example
// String myString = intent.getString("myStringFrom2ndActivity")
}
}
}
and also make sure that you are calling the right RESULT_OK. It should be something like Activity.RESULT_OK.
I am trying to pass data backwards to an activity, however I can never get my onActivityResult function to be called. When I start the new activity, I create a new intent like regular
Intent intent = new Intent(this, NewLoanCost.class);
intent.putExtra("defaultsArray", jDefaultsArray.toString());
intent.putExtra("loanSelection", loanSelection);
intent.putExtra("buyerSellerSelection", buyerSellerSelection);
startActivity(intent);
and when I want to go back to the previous activity, I am overriding the back button to create a new intent and store the data
#Override
public void onBackPressed() {
Intent intent = new Intent();
intent.putExtra("fullCosts", fullCosts.toString());
setResult(RESULT_OK, intent);
super.onBackPressed();
}
but in the first activity, I can't even get a debugging toast to appear. Am I missing something blatant?
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
//super.onActivityResult(requestCode, resultCode, data);
Toast.makeText(this, "onActivityResult", Toast.LENGTH_SHORT).show();
if (requestCode == 1) {
if(resultCode == RESULT_OK){
try {
jDefaultsArray = new JSONArray(data.getStringExtra("fullCosts"));
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
To receive a result you should use startActivityForResult instead of startActivity
Change your code to
Intent intent = new Intent(this, NewLoanCost.class);
intent.putExtra("defaultsArray", jDefaultsArray.toString());
intent.putExtra("loanSelection", loanSelection);
intent.putExtra("buyerSellerSelection", buyerSellerSelection);
startActivityForResult(intent, 1);
the second parameter is an int with the request code you will use in onActivityResult
Use startActivityForResult.
Replace your code with this, then it should work:
Intent intent = new Intent(this, NewLoanCost.class);
intent.putExtra("defaultsArray", jDefaultsArray.toString());
intent.putExtra("loanSelection", loanSelection);
intent.putExtra("buyerSellerSelection", buyerSellerSelection);
startActivityForResult(intent);
I want to receive data in previous Activity from next activity like (1 <--- 2 ). I tried but data is not received from second to first activity .
This is First Cativity
Intent i = new Intent(CustomActionActivity.this, Edit_Post.class);
i.putExtra("ActivityId", getItemActivity);
i.putExtra("Vessel", strVesselName);
i.putExtra("HashTag", strHashTag);
i.putExtra("RemarkTitle", strRemark);
i.putExtra("ShortRGN", strShortTypeRGN);
i.putExtra("VessId", strvesselid);
startActivity(i);
This is second Activity
Intent intent = getIntent();
strActivityId = intent.getStringExtra("ActivityId");
strVesselName = intent.getStringExtra("Vessel");
strHashTag = intent.getStringExtra("HashTag");
strRemark = intent.getStringExtra("RemarkTitle");
strShortRGN = intent.getStringExtra("ShortRGN");
strVessId = intent.getStringExtra("VessId");
img_AddPostAudio.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i = new Intent(Edit_Post.this, EditRecord.class);
i.putExtra("EditVesselId", strVessId);
i.putExtra("EditActivityId" , strActivityId);
startActivity(i);
}
});
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
if(requestCode==REQUEST_CODE)
{
String audioString=data.getStringExtra("AUDIO_STRING");
Log.e(" audioString "," = "+audioString);
}
}
This is Third Activity
Intent intent = getIntent();
vesselId = intent.getStringExtra("EditVesselId");
strActivityId = intent.getStringExtra("EditActivityId");
Intent intent=new Intent(EditRecord.this, Edit_Post.class);
intent.putExtra("AUDIO_STRING",newAudioFile);
setResult(REQUEST_CODE, intent);
finish();
do this when you are calling the second activity
Intent i = new Intent(CustomActionActivity.this, Edit_Post.class);
i.putExtra("HashTag", strHashTag);
startActivityForResult(i, REQUEST_CODE);
Now you need to set the result what you want on CustomActionActivity
e.g.
Intent intent=new Intent();
intent.putExtra("MESSAGE",message);
setResult(REQUEST_CODE,intent);
finish();
Now you will get this data to the your first activity
e.g.
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
if(requestCode==REQUEST_CODE)
{
String message=data.getStringExtra("MESSAGE");
textView1.setText(message);
}
}
let me know in case of any issue
Use SharedPreferences
Store the data in a SharedPreference and access it in from the SharedPreference in the other activity.
Add the data to the SharedPreference in the onStop for the 2nd Activity and access it in the onCreate of the other Activity
#Override
public void onStop(){//Where you wish to insert data
SharedPreferences data=getSharedPreferences(PREFS_FILE,0);
SharedPreferences.Editor editor= count.edit();
editor.put("data","DATA");
editor.apply();
super.onStop();
}
in onCreate() of the other Activity:
SharedPreferences data = getApplicationContext().getSharedPreferences(PREFS_FILE, 0);
String dataString=data.get("Data",0);
Hope this helps. Cheers.
I am doing this way its works for me:
Activity 2:
public void onBackPressed() {
// TODO Auto-generated method stub
Intent intent = new Intent();
intent.putExtra("MESSAGE", strtext + "");
setResult(2, intent);
if (isclose) {
finish();
} else {
super.onBackPressed();
}
}
}
Activity1:
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
String sSuName = data.getStringExtra("MESSAGE");
//txtfavouratecount.setText(sSuName);
}
in Your onclick listener
Intent itemintent = new Intent(context,your target Activity.class);
Bundle b = new Bundle();
b.putStringArray("iarray", Qtag);
b.putInt("mflag", 0);
itemintent.putExtra("android.intent.extra.INTENT", b);
startActivityForResult(itemintent,2);
I would do something like this:
In Activity A:
private static final int REQUEST_CODE = 9001;
Intent intent = new Intent(this, ActivityB.class);
startActivityForResult(intent, REQUEST_CODE);
In Activity B:
Intent data = new Intent();
data.putExtra("key", parameter);
setResult(CommonStatusCodes.SUCCESS, data);
finish();
And finally, in the Activity A, receive result:
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_CODE) {
if (resultCode == CommonStatusCodes.SUCCESS) {
if (data != null) {
String result = data.getStringExtra("key");
}
} else {
//Error to receive data
}
}
else {
super.onActivityResult(requestCode, resultCode, data);
}
}
Good luck!
i have button which have attribute android:onClick="atnDuom".
There is that function
public void atnDuom(View view)
{
finish();
}
and there is onActivityResult function in the same activity.
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1) {
if (resultCode == RESULT_OK) {
DOP = new DatabaseOperations(ctx);
Intent returnIntent = new Intent();
user_name = data.getStringExtra("tarpVard");
user_lastname = data.getStringExtra("tarpPav");
institucijos_pavadinimas = data.getStringExtra("tarpInst");
padalinio_pavadinimas = data.getStringExtra("tarpPad");
pareigos = data.getStringExtra("tarpPar");
mob_tel = data.getStringExtra("tarpMob");
el_pastas = data.getStringExtra("tarpEl");
setResult(RESULT_OK,returnIntent);
DOP = new DatabaseOperations(ctx);
if(newVard.equals("")||newPav.equals("")||newInst.equals("")||newPad.equals("")||newPar.equals("")||newMob.equals("")||newEl.equals(""))
{
Toast.makeText(getBaseContext(), R.string.prashome, Toast.LENGTH_LONG).show();
}
else
{
DOP.updateUserInfo(DOP, user_name, user_lastname, institucijos_pavadinimas, padalinio_pavadinimas, pareigos, mob_tel, el_pastas, newVard, newPav, newInst, newPad, newPar, newMob, newEl);
Toast.makeText(getBaseContext(), "Duomenys atnaujinti", Toast.LENGTH_LONG).show();
finish();
}
}
}
}
It is possible to execute function onActivityResult whithout doing anything in atnDuom function?
Finish() close activity and onActivityResult doesnt work :)
You are using data from the intent, if you want to go to onActivityResult from atnDuom you will need to create a new Intent and push all the data needed
Intent newIntent = new Intent();
newIntent.putExtras(...);
onActivityResult(REQUEST_CODE, RESULT_OK, newIntent);
