[android-developers] Re: When the new activity starts, the data of previous activity is gone.
Hi Rui Wu, I got the solution of get back to the first activity by pressing previous button without changing data of first activity. Now, the user will enter his credentials. When he click to proceed further, the credential details will directly go to the server and server gives response with the cookie and that cookies should be store in my phone for the usage for the future. It means that when the user again run the application he should directly loggedin in to the application, e.g., www.mail.yahoo.com. If you have any idea as mentioned above, please share me. Thanks.

Re: [android-developers] Re: When the new activity starts, the data of previous activity is gone.
Hi Pranav, I didn't catch the point for your second problem. Do you want to pass the value of edittext in first activity to second activity, then show the strings in the edittext of second activiy. If so, you can try in the similar way as the first problem. BRs, Rui 2010/1/1 android09 pranav.jaja...@gmail.com Hi Rui Wu, Thanks a lot. It works very good and perfectly as i want. Now, i know that where was my problem. Actually, i had not added this line/lines : mData.strFirstName = edFirstName.getEditableText().toString();. That's why i was not getting any result. Now, i got it. I have also one query. I have two activities. First activity consist on edittext and button whereas second activity consist only edittext. When i write in edittext of first activity and press a button of first activity than the edittext of second activity should get the same string. Actually, i want to get the email id from the first activity and also it should be automatically get in the edittext of second activity. If you have any idea about it, please tell me.

[android-developers] Re: When the new activity starts, the data of previous activity is gone.
Hi Rui Wu, I got the solution of the second problem. Actually, i have used the same string value for the both fields. It means i have used the same string value for the edittext in the first activity as well as in second activity which has also one edittext. When i press next button it takes the string, entered by the user and it shows in the edittext of the second activity. By the way, thank you for communicating with me.

Hi netiger198610 and Lance Nanek, First of all thank you for reply me. Now i am coming to the point. Yes, netiger, i want exactly this thing, that whenever the new activity starts, the data should not go elsewhere it should be there when i press Previous button of my project(do not consider the back button of emulator, but i want the same functionality like that.). How can i do that can you give me an example or any idea, how to do that. I really need it because i can't go further more without getting the data from the previous activity. Please give me any idea or example of to hold the data in the previous activity when the new activity is started. Thank you.

[android-developers] Re: When the new activity starts, the data of previous activity is gone.
Well, surely you just need to populate the fields within the onCreate () methods? 1) Have an object in the Activity which holds the data that the user enters. (Populate them when the user moves to the next activity). 2) On the next Activity, if the user presses the 'Previous' button, pass in Intent which indicates that the user is coming back from that activity. 3) When the original activity is called again, check for the presence of the Intent, and if it's coming back from the other activity, the data will already be populated in your object, which you can use to populate the various text fields. Hope that helps... On Dec 31, 11:15 am, android09 pranav.jaja...@gmail.com wrote: Hi netiger198610 and Lance Nanek, First of all thank you for reply me. Now i am coming to the point.

[android-developers] Re: When the new activity starts, the data of previous activity is gone.
In fact, even simpler... Just have an object in your activity which holds the data from the fields. Then everytime the activity loads, populate the fields from the onResume() method, if the object and the data exists. -- You received this message because you are subscribed to the Google Groups Android Developers group.

Hi Neilz, Thank you for reply me with the proper and useful idea. I tried to hold the first activity data but it gives error while loading the data. It is not allows me to get data back. Can you understand me by the code? How can i hold the first activity's data when i start another activity and get back to previous. I also tried with the onPause() and onResume() methods.

Re: [android-developers] Re: When the new activity starts, the data of previous activity is gone.
Hi Pranav,
I guess you implemented your logic like this:
Button previous = (Button) findViewById(.);
previous.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
Intent i = new Intent();
i.setClassName(the name of the previous activiy.);
startActivity(i);
}});
Try the below way:
Button next = (Button) findViewByid(.);
next.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
Intent i = new Intent();
i.setClassName(the name of the next activity.);
i.putExtra();... //to pass this activity's data to next
startActivity(i);
}});
Button previous = (Button) findViewById(.);
previous.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
finish();
}});
What you need to do is passing the current activity's data to next
Activity; When you press the Prev button, you will find Android keeps
the inputed strings in the EditText and other editable views
automatically...
Hope this can help you.

Re: [android-developers] Re: When the new activity starts, the data of previous activity is gone.
Hi Pranav,
The way in the previous mail has an issue: if user inputs sth. in Current
activiy named Activity2, then Presses Prev, the previous Acitivy named
Activity1 does keep the inputed contents in UI, however when user
presses Next here to go to Activity2, Activity2 will not keep the data
inputed by user.
Another solution: Construct a Class for your registration info i.e. Person
which implements Serializable interface.
1. For each activiy, implements the 2 buttons' logic like this:
next.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
update person according to the cotents inputed by user
Intent i = new Intent();
i.setClassName(the name of the next activity.);
i.putExtra(Person, person);... //to pass this activity's data
to next
startActivity(i);
finish();
}});
previous.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
update person according to the contents inputed by user
Intent i = new Intent();
i.setClassName(the name of the previous activity.);
i.putExtra(Person, person);... //to pass this activity's data
to next
startActivity(i);
finsh();
}});
Of course, special logic is needed for the first activity's Back button
the last activity's Next button;
2. Add below code in OnCreate() :
Intent i = getIntent();
person = (Person)i.getSerializableExtra(Person);
if(person != null) {
update the editable ui controls according to the value of person's
member variables
} else {
person = new Person(); // this will only happen in the first activiy
}
3. For the back key handle, use the same logic as Prev button to
set onKeyListener for the activiy.
BRs,
Rui
