Android :: How To Set / Pass Values From One Screen (activity) To Another?
Sep 30, 2010
How do you set/pass values from one screen (activity) to another? What I have in the R.layout.main view labeled Calculator contains the code for doing calculations. The main.xml contains the layout (view) of the main screen. I have created an options menu which has another screen which shows you setup (R.layout.setup). The dialogsetup.xml contains the layout (view) for it.
When you press the menu button, you get the options menu. If you select "Setup", then it will display the setup screen. Now what I need to do is take the values from the setup screen (radio button and text values) and place them in the main screen so that when you exit the setup screen and go back to the main screen, you can take those values and use them in your main code.

Is there any way to pass values(strings or bundles) to another application while calling it via intents, and also return some information (mostly string)?

I have an app which makes use of several layout-views. Every layout - view also got a class for it, which extend the Activity class. One class for example retrieves some database values whilst offering a search form to the user. Afterwards the user can select one of those values and he gets presented with another screen which gives similar options as the one selected. Anyways, I'd like for the first Activity to be able to send an array with data (Strings for example) to the second one. Right now I show an activity by using:
Intent i = new Intent(this, activitysName.class); startActivity(i);
I have no idea whilst using this construction how I can "initialize" the new object with the String array I want to pass to it. So how should this be achieved ? Should I be using something else instead of an Intent-Activity combination ?

In my Android app,I start a new activity with startActivityForResult(). I get the result in onActivityResult() perfectly. My problem is that there is a small bit of data that I know before I start the activity and I need that value to be available in onActivityResult(), too. I tried attaching it to my intent as an extra, but it wasn't attached to the intent that is available when the activity returns the result. I made it work by storing the data in a global variable, but I really don't like that approach. Is there a better, right way to pass data through an activity (instead of just to it)?

Assume that there activity A and B, A has a handler, now B is activate by A, how can i pass the handler to B? Currently i have a thread receive messages from socket, and dispatch messages to A and B, I think when B is activated, pass handler to B, then the handler can receive message from the thread. But I don't know how to do.

I have an activity which implements an OnItemClickListener.code...
However, I need to pass some objects from MyActivity1 to MyActivity2 --
I see there is an Intent.putExtra() for all the basic types, and I even see a Bundle which is a collection of basic types, but how can I pass a generic "Object" to MyActivity2 ?

I figured out how to pass a String value between activites thanks to this site, however I'm having trouble passing an image. What I'm trying to to is have a user click a button that opens the gallery and allows selecting of a picture. Then I have another button that opens another activity that displays an ImageView. I want to be able to have that ImageView's image be the chosen one from the previous activity.
Here is the class that has the button I'm clicking to open the gallery and retrieve the chosen image: code...
What I'm not sure about is in the OnActivityResult if I should pass the selectedImage or the chosenimage in the b.putExtra("bitmap", selectedimage); line. I tried both but I didn't see an image on the second activity. Also I wasn't sure in the PreviewScreen class if I'm setting the imageview correctly. Any help is appreciated. Thanks.

I have a need where I must pass some values from an Activity to another file which extends View class (instead of Activity). Its not the normal passing of values from one activity to another. In my Activity, I will pass some co-ordinate values to the class that extends View. In this class, I will draw an image and place points over the image on the required co-ordinates. But, the problem is, I cant send values using Intent.

I have an application which has 2 screens. When a value is changed in the second screen and when the first screen is called, the value must be updated on the button of first screen.
But I am not able to update the value on any of the widget of first screen. But I am able to see that I am getting the value, But when it comes to updating the same on button it does not happen.

I am want to pass data back from a Thread to Activity (which created the thread). So I am doing like described on Android documentation.Only one thing I am missing here - where and how should be defined mResults so I could access it from both Activity and Thread, and also would be able to modify as needed? If I define it as final in MyActivity, I can't change it anymore in Thread - as it is shown in example.

I wounder if there is some possible to know from which parent Iam coming from in the child so I can do different stuff depending on who the parent is of the activity.This is how Iam going over to the child. But I don't know how to handle this in the child to check who is the parent. The above code is used on one of the parents,, is there somehow I can use "EQ_CODE_SELECT_LOCATION"? Also I wounder how is possible to send data to a child activity?

So I have a MapActivity that runs an asynchtask that occasionally updates what exactly it's displaying on the map (via a string). I originally pass this string in from the intent when the activity is first created. And then if you click on one of the drawables on the map, it opens a new activity, which can then create a new mapview (same class) with a different string setting. The problem I have is that I only want one instance of the mapview to be running at once. Thus I set android:launchmode="singletask" in the manifest. This works in that it brings the mapactivity to the front, but is there any way to send it a new intent bundle to get a new setting for the string it needs? I tried regetting the extras from the bundle, but it seems to retain the old bundle, not the new intent that was passed to it. I'm not sure I want to do startActivityForResult because the 2nd activity may or may not want to update the original activity. I hope that made sense. I can post code if necessary, but I think that should explain my situation.

I'm working on an app, and one activity has a worker thread that initiates a database query, and if there are results once it has returned I would like to send these results to a new activity that will display them. Unfortunately I don't see a way to pack the Cursor object into the Intent object that I am using to start the new activity. When I was doing Windows Mobile development in the past all I would do is edit the constructor for the window to pass in the data, I've searched around but I can't find a similar solution for Android. What is the best way to pass my database results into the new activity?

I have an ArrayList of type GeoPoint.
private List<GeoPoint> points = new ArrayList<GeoPoint>();
I want to pass points to another Activity and retrieve the data in that activity. How do I do it? I know I have to use the parcelable but I searched, but could not find a way to pass ArrayLists.

How can I pass a string from an activity to a layout?
I can pass arrays from an activity to a layout with the following activity code...
Is there a simpler way to just pass a single string instead of any array of strings, from an activity to a layout?

I want to pass a String like the input of a new activity, to let this one use the String some operations. The code I try is this..
And in the activity I try to recover it:
String textout = savedInstanceState.getString("contactcode");
In the onCreate part. I have seen that uris are normally used, but I don't know how to pass that String by using a URI.
