I have 2 activities in my Android application, Activity1 and Activity2.
I want to display the data retrieved from a String in Activity2 and this string value set text in Activity 1 textview when back is pressed from Activity2.
Please anyone give the solution for this problem,thanks in advance.
Activity 2: here I pass the string value to Activity 1 when I back press the Activity 2 this will be retrieved to Activity 1.
public void onBackPressed() {
// TODO Auto-generated method stub
NoolDataBaseHelper db = new NoolDataBaseHelper(NoolDashboardDetailPage.this);
int strtext = db.getProfilesCount();
db.close();
Intent intent = new Intent();
intent.putExtra("Obj", strtext+"");
setResult(Activity.RESULT_OK, intent);
if (isclose) {
finish();
}
else
{
if (!isplays) {
inflateLoginlayout.setVisibility(View.GONE);
topview.setVisibility(View.VISIBLE);
isplays = true;
//edtnames.getText().clear();
}
else
{
super.onBackPressed();
}
}
}
Activity1: here i retreive the string from Activity 2 and set the string value to my textview
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 1) {
if (resultCode == Activity.RESULT_OK) {
String sSuName = data.getStringExtra("Obj");
txtfavouratecount.setText(sSuName);
} else if (resultCode == 0) {
}
}
}
You should follow this structure
In Activity 1
Intent intent=new Intent(Activity1.this,Activity2.class);
startActivityForResult(intent, 2);// Activity is started with requestCode 2
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
// check the request code here is 2
if(requestCode==2){
if(resultCode == 3){ // check the result code
String message=data.getStringExtra("MESSAGE");
// set text for your textview
textView1.setText(message);
}
}
}
In Activity 2
public void onBackPressed() {
String message = "abc";
Intent intent=new Intent();
intent.putExtra("MESSAGE",message);
setResult(3,intent); // 3 is result code
super.onBackPressed();
}
Hope this help

I am starting an activity with startActivityForResult like this
#Override
public void onEmptyViewClicked(Calendar time) {
Bundle bundle = new Bundle();
bundle.putSerializable("time",time);
bundle.putInt("fragmentId",1);
Intent intent = new Intent(this,AddEventActivity.class);
intent.putExtras(bundle);
startActivityForResult(intent,1);
}
and in AddEventActivity i add fragments depending on the fragment id.The first fragment add events and second fragment delete events.onAddEvent and onDeleteEvent i setResult with appropriate data like this
#Override
public void onAddEventClicked(Bundle bundle) {
Intent intent = new Intent(this,MainActivity.class);
intent.putExtras(bundle);
setResult(1,intent);
finish();
}
#Override
public void eventDelete(Events event) {
Bundle bundle = new Bundle();
bundle.putSerializable("deleteEvent",event);
Intent newIntent = new Intent(this,MainActivity.class);
newIntent.putExtras(bundle);
setResult(2,newIntent);
finish();
}
OnActivityResult code is something like this
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(resultCode == 1 && data != null){
if(requestCode == 1){
}
}else if(resultCode == 2){
}
}
}
Now onActivityResult is getting called onAdding event but not on deleting event.eventDelete method is getting called but it is not triggering onActivityResult.What could be the problem?Thankyou.
UPDATED
I put a debug at first line in onActivityResult but debugger doesn't stop there.
startActivityForResult(intent,1);
here 1 is your requestCode
setResult(1,intent);
here 1 is your resultCode
you are setting same resultcode for Two events
change your onActivityResult to
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == 1) { //add event
if (requestCode == 1) {
if (data != null) {
if (data.getExtras().containsKey("deleteEvent")) {
} else {
}
}
}
} else if (resultCode == 2) { //delete event
//write code
}
}
you should add RESULT_OK and validate this resultCode:
Intent returnIntent = new Intent();
returnIntent.putExtra("returndata");
setResult(Activity.RESULT_OK, returnIntent);
finish();
after this, u need add the validation in your onActivityResult method...
if(requestCode == CODE_REQUEST){
if(resultCode == Activity.RESULT_OK){
//do something here
}{
//catch cancel result
}
}
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 Three Activity A,B,C.
From A activity I send it to B using startActivityforResult and then from activity B I Send it to Activity C using startActivityforResult but when I came back to activity A from all activities with RESULTOK than i got no data on activity A and every thing refresh on bluestack but its working fine on Samsung and Motorola as I had tested on that.
So I want it to be working on all devices.
I had set my activity orientation to Portait statically in all activities.
Code:
Acitivity A:
Intent i = new Intent(v.getContext(),B.class);
startActivityForResult(i, 1);
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
if (requestCode == 1) {
String result = data.getStringExtra("imagesreturn");
}
}
}
Activity B:
ImageButton btn = (ImageButton)findViewById(R.id.button_capture);
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent i = new Intent(CameraUiActivity.this, CameraImageTakenActivity.class);
i.putExtra("image", f.getAbsolutePath());
startActivityForResult(i, 1);
// dialog.dismiss();
}
});
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1) {
if(resultCode == RESULT_OK){
String result = data.getStringExtra("images");
Intent intent = new Intent();
intent.putExtra("imagesreturn",result);
setResult(RESULT_OK, intent);
finish();
}
if (resultCode == RESULT_CANCELED) {
//Write your code if there's no result
finish();
}
}
}
Activity C:
final String myimage = b.getString("image");
btnsave.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent();
intent.putExtra("images",myimage);
setResult(RESULT_OK, intent);
finish();
}
});
I have the next activities:
Activity1
//declare
private static final int SAVE_DATA_FROM_ACTIVITY = 203;
//........... not important code
//button to open second Activity
public void btn_openSecondActivity(View view)
{
Intent intent = new Intent(Activity2.this, Activity1.class);
startActivityForResult(intent, SAVE_DATA_FROM_ACTIVITY);
}
}
protected void onActivityResult (int requestCode, int resultCode, Intent data)
{
if (requestCode == SAVE_DATA_FROM_activity)
{
name= data.getStringExtra("Name");
}
}
//....... not important code
Activity2
On Second Activity I have two buttons:
Cancel
Save
//............
//declare
private static final int OK_RESULT_CODE = 1;
//Cancel button
public void btn_cancel(View view)
{
finish();
}
//Save button
public void btn_save (View view)
{
Intent intent = new Intent();
intent.putExtra("Name",et_name.getText().toString());
setResult(OK_RESULT_CODE, intent);
finish();
}
PROBLEM
When I click Save button all works perfect, but the problem it's when I click Cancel button, then it's reports an error:
Failure delivering result ResultInfo{who=null, request=203, result=0, data=null} to activity {com.example.alvaro.project/com.alvaro.project.Activity1}: java.lang.NullPointerException
I understand the problem, when I cancel is not the same result code but i don't know how I can solve it
Any suggestions?
You have issue in onActivityResult method. You don't check result.
Change your condition from :
if (requestCode == SAVE_DATA_FROM_activity)
to:
if (resultCode == OK_RESULT_CODE && requestCode == SAVE_DATA_FROM_activity)
Change this
if (requestCode == SAVE_DATA_FROM_activity)
{
name= data.getStringExtra("Name");
}
into
if (requestCode == SAVE_DATA_FROM_activity&&resultCode==RESULT_OK)
{
name= data.getStringExtra("Name");
}
and
Your cancel method is like
public void btn_cancel(View view)
{
setResult(RESULT_CANCELED);
finish();
}
And instead of OK_RESULT_CODE use Android default ok like Activity.RESULT_OK
Check if you manage to set the result
protected void onActivityResult (int requestCode, int resultCode, Intent data)
{
if (requestCode == SAVE_DATA_FROM_activity && resultCode = Activity2.OK_RESULT_CODE)
{
name= data.getStringExtra("Name");
} else {
//probably btn_cancel pressed
}
}
check resultCode in onActivityResult
protected void onActivityResult (int requestCode, int resultCode, Intent data)
{
if (resultCode == 1/*OK_RESULT_CODE from Second Activity */ && requestCode == SAVE_DATA_FROM_activity)
{
name= data.getStringExtra("Name");
}
}
Activity1
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == SAVE_DATA_FROM_activity) {
if (resultCode == Activity.RESULT_OK) {
name = data.getStringExtra("Name");
} else if (resultCode == Activity.RESULT_CANCELED){
// TODO something
}
}
}
Activity2
delete field OK_RESULT_CODE
//Cancel button
public void btn_cancel(View view) {
setResult(Activity.RESULT_CANCELED, new Intent());
finish();
}
//Save button
public void btn_save(View view) {
Intent intent = new Intent();
intent.putExtra("Name", et_name.getText().toString());
setResult(Activity.RESULT_OK, intent);
finish();
}
In my app I have a header with icon hidden, I have a adapter with a listview when I click the listview I go to a login screen using listener, when the login is successful is should come back to listview(adapter) and icon should get visible on header. i am sending intent as follows: http://pastebin.com/4SKnyjVX
below is onclick the login button
public void onClick(View v) {
String password = etPassword.getText().toString();
if(password.equals("guest")){
Intent returnIntent = new Intent();
returnIntent.putExtra("result",result);
setResult(1,returnIntent);
finish();
} else {
//----
}
finish();
}
how can i use onActivityResult to set a flag and use this flag in click listener,
and also use it to make the icon visible. Any suggestion is appreciated
You have to override onActivityResult(int requestCode, int resultCode, Intent resultIntent):
requestCode is the integer that you originally passed as the second parameter to startActivityForResult(). You should check this matches your original request, in case you have multiple requests you have to differentiate between.
resultCode and resultIntent is the integer and intent you pass to setResult() in your code above.
So your method should look something like:
#Override
public void onActivityResult(int requestCode, int resultCode, Intent resultIntent) {
if (requestCode == 1) { // original request
if (resultCode == 1) { // success
String result = resultIntent.getStringExtra("result");
// Login successful, update your model and call adapter.notifyDataSetChanged() or something
}
}
}
In your previous activity where you have listview with hidden icon in header, override the function onActivityResult() something like this -
protected void onActivityResult (int requestCode, int resultCode, Intent data) {
boolean success = data.getBooleanExtra("result", false);
if(success) {
hiddenIcon.setVisibility(View.VISIBLE);
}
else {
showDialog("Error");
}
}
And I've changed your onClick this way
public void onClick(View v) {
String password = etPassword.getText().toString();
Intent returnIntent = new Intent();
if(password.equals("guest")){
returnIntent.putExtra("result", true);
setResult(RESULT_OK, returnIntent);
}
else {
returnIntent.putExtra("result", false);
setResult(RESULT_OK, returnIntent);
}
finish();
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
if(resultCode==RESULT_OK){
Bundle basket=data.getExtras();
String s=basket.getString("result");
//Your Code Here
}
}
This will be helpful
