Android :: BringtoFront The Parent Activity?
Sep 7, 2010
As we know, startActivityForResult() used to get a result for a task from parent activity. Here when we click the setResult(). It returns the result to the parent Activity.
Child Activity means it should maintain the persistent state. That is when the users clicks a button on the child activity. It do not finishes that activity and show the Parent Activity. And again i may go to the child activity from parent activity. If the child does not exists it starts a new child activity else it should show the existing child activity with persistent content.
Simply said, my parent Activity starts a new Child Activity. Now both Activities should be alive. How to call the Parent Activity without finishing the child Activity(in other words, How to BringtoFront the parent Activity)? For this scenario,
you can not use startActivity(). Because it creates a new Activity Instance. Not Existing Parent Activity
you can not use startActivityForResult(). Because it finishes the child Activity Instance.

I have a main screen with buttons to launch other subactivities. I have to press back button each time to go back to the main screen of my application. How do I finish a child activity and automatically return from the caller?

Can someone tell if why when starting an activity with startActivity(intent) , calling getParent() in onCreate() of the new created activity returns a nul ?
Also how could I obtain the parent of an activity created in such a way ? Can a reference of the activity below the current activity in the activity stack be obtained ?

My child activity X is called from Parent activity P through startActivity(intent). I want to close P when X called its finish() method. I override a method finishFromChild(Activity child) in P and called finish() in it. But this functions (finishFromChild(Activity child)) is not being called after X finish() Is it a known bug or I am missing some thing? I googled and also searched the groups but no help.
An alternative could be... using StartActivityForResult() and a "fake" onActivityResult, where I can finish the parent activity, but this way is quite bad, i think...
I prefer the first one, if it would work....

Any idea why this doesn't create an activity that looks like a popup instead of an activity that completely fills the screen?
CODE:.............
I assumed that I only needed to set the layout height and layout width to something other than "fill_parent", but it still shows up as a black screen that completely fills the screen.
Ultimately, I simply want to create a popup, but I do not want to use an AlertDialog. Is this possible?

I have a parent activity, and a child activity that extends the parent activity. When the parent starts the child activity,
Which onCreate gets executed first? The child's or parent's?
There is a particular variable I am setting in the Child activity's onCreate method, and right now, it looks like it takes a while to get to the Child activity's onCreate, and so the methods in the Parent are reporting an empty variable. Whereas when I make the Parent sleep for a while, it reports the correct variable.
CODE:............
So, basically, even after the Parent starts the Child, it still returns "Parent Value", but when I have the thread sleep, it return "Child Value".

My application supports twitter and needs to open browser for OAuth. When the user clicks the Share on Twitter button, the main activity will create another subactivity (TwitterActivity) to handle twitter authentication issues. Here is a flow graph showing how activities are invoked currently. Main is short for MainActivity and Twit for Twitter Activity. startActivity() OAuth intent OAuth callback finish()Main ---------------> Twit ------------> Browser --------------> Twit --------> Browser As you may notice, after the TwitterActivity calls finish() to stop, it will now return back to MainActivity, but Browser instead. How can I make it return back to MainActivity?

I wish to re-use the Contacts application in a way to enable the user to pick a contact and return it to the parent activity (my application's activity).
For achieving this, I want to inquire about the kind of Intent that will be needed to launch the contacts application.
Intent i = new Intent(Intent.ACTION_GET_CONTENT, ?); startActivityForResult(.....);
What should be the second argument here ?
In the deprecated Contacts API, I could use the following snippet, but not sure about ContactsContract:
Intent i= new Intent(Intent.ACTION_GET_CONTENT,People.CONTENT_URI); startActivityForResult(i, reqCode);

I want to do some cleanup in a view when the activity is being destroyed. Is there any way to get a callback in the View when the activity is being destroyed? I tried using onDetachedFromWindow, but I'm not sure whether it is correct thing to do.

In one of my Activities I have a ListView that displays a list of locations. For each list item I want a little arrow icon that points in the direction of the corresponding location. I implemented this icon by extending ImageView. This custom View has a listener that reacts to changes of the device's orientation by rotating the icon image accordingly. I register the listener in the onAttachedToWindow() method and unregister it in onDetachedFromWindow(). This kind of works but the problem is that onDetachedFromWindow() sometimes gets called only a long time after the containing Activity has paused. Also, the whole layout overall seems a little hacky. So my question is: Is there a proper way to unregister the listeners or would you implement this in a completely different way to begin with?

Is there an exception in the lifetime rules for a parent activity that's in the background after invoking startActivityForResult()? From my understanding, in low memory scenarios, the background activities are killed before the foreground. Does this rule still apply even if the background activity started the foreground one for the purpose of obtaining some result?
In this case, I think it would make sense for the foreground child activity to get killed first or to equalize the lifetime of the parent and child.

I basically have three activities X, Y, Z and I want only one instance of each but I want control over the navigation and I can't do that by putting all three activities in one task because of the stack structure.
Here is a scenario, from X I launch Y given a certain "id" which correspondence to specific data in the DB, Y inflates and populates it's views, then I go back to X and launch Y again with a different "id" in the intent, I don't want the overhead of launching the activity and inflating the views again, anyone know how to do this?
I tried using singleInstance, but the problem is that I can't send the result code back to an activity in a different task.

The order is:
A: startActivityForResult( B ) B: <dostuff>, call finish() A: onCreate <---- what's this all about A: onActivityResult
This happens for a tiny minority of users. I havn't been able to reproduce or find any common elements. A is the launch activity.

I wish to have a single class which all of my Activity classes extend. I have ListActivities, Activities, MapActivities, TabActivities, etc in my App.
I have many of these different activities in my app, ~12 activities. I want each of them to have the methods which are in the parent class.
Right now, i have created 4 parent activity classes which are extended from a certain activity depending on their type(ListActivity, Activity, MapActivity, TabActivity)
I am creating a lot of redundant code - each of the 4 parent activities has almost identical code, in exception for what class activity it extends.
Here is an example that may clarify what my problem is:
I have an Activity: MenuScreen which extends BaseListActivity BaseListActivity extends ListActivity BaseListActivity contains methods and fields which i want all my activities to have access to I have another Activity: HomeScreen which extends BaseActivity BaseActivity extends Activity BaseActivity contains the same methods and fields which are in my other Base[<type>]Activity classes(such as BaseListActivity)
These methods/fields are copy-pasted to all my Base[<type>]Activity, and seems awfully redundant to me.
Can i create a master activity class which all types of Activity classes can use as its parent? if not, am i stuck with copy and pasting this code and feeling gross/dirty about it?

I have two activities: a MainListActivity, and a DetailViewActivity. DetailViewActivity is set with android:launchMode="singleTop".
When clicking an item in the "main list" activity, it launches the "detail view" activity via:
startActivityForResult(detailIntent, REQUEST_CODE_DETAIL);
If I then call setResult(RESULT_OK, resultData); and finish(); from within the Detail activity, that resultData is received by the "main list" activity's onActivityResult(..) method correctly.
However, if I implement a "see previous"/"see next" type of navigation within the Detail activity, and implement it using singleTop, that result no longer gets sent back to the initial activity:
Intent nextItemIntent = this.createIntent(nextId);
nextItemIntent.setFlags(Intent.FLAG_ACTIVITY_FORWARD_RESULT);
startActivity(nextItemIntent);
// at this point, my DetailActivity's onNewIntent() method is called, and the new data is loaded properly
But from here, when I call setResult(..) and finish(), my MainList activity never receives the new/updated result. Anyone know what I'm doing wrong?

I have an application, which (for the sake of simplicity) has two types of activities - Overview and DetailView. The Overview activity shows a list of steps and allows the user to start a DetailView activity corresponding to the step chosen.
In the DetailView activity, the user can start another Overview, which shows different steps than the ones in the parent of the current DetailView.
In the Overview, DetailView is started by using startActivityForResult (). In the DetailView, when the user decides to start a second Overview, I call setResult () and finish () and then start the new Overview. In this scenario, onActivityResult () and finishFromChild () do not fire. Instead, they fire when the parent finishes (?).
Code from Overview:

Code from DetailView:

I have a SurfaceView that is covering a portion of its parent, a RelativeLayout. I have a background image covering the full RelativeLayout area, and this is my Activity's main layout.
I would like to have the SurfaceView be transparent so that I can see through to the background image on its parent RelativeLayout. I have tried the approach shown in the API Demos example TranslucentGLSurfaceViewActivity, but this succeeds in making the transparency go all the way through my Activity to my desktop!
I'm using the "style/Theme.Translucent" theme on my activity, and setting this on my SurfaceView: mySurfaceView.getHolder().setFormat(PixelFormat.RGBA_8888);
The transparency to the desktop it kinda cool, but not what I'm trying to do! Is it possible to make a SurfaceView transparent only through to its parent?

I want to determine the available height and width of the parent layout to which I have to add my view.I have used many methods on layout like
layout.getHeight()
layout.getRootView().getHeight()
All these methods return 0(zero) as the result.My main requirement is to be able to give width to a view that is some % of the width of the layout.Also I dont want to use tag for this. I want to do it through code.

I have a simple ExpandalbeList. For the group header view, I'm using a simple TextView, I am setting the background of the text to a drawable. I have the textview parameters set to FILL_PARENT, but the background of the TextView only covers the width of the text. I realize that I can put this all inside of a Linear Layout, but that just seems like a waste. isn't there a way to make the bounds of the text view stretch to the edge of the listview?

As an exercise I attempted to add an AppWidgetProvider-derived class to one of our existing Android applications. When the widget is created and appears on the home screen, the output from adb logcat notes: W/ActivityManager(58): Unable to launch app com.mycompany.myapp/ 10042 for broadcast Intent { action=android.appwidget.action.APPWIDGET_ENABLED comp= {com.mycompany.myapp/com.mycompany.myapp.MyAppWidgetProvider} }: process is bad
This output comes from around line 10814 in ActivityManagerService (looking at cupcake on git). This is running on an ADP 1.5, FWIW. The same AppWidget code, once separated from the main application's project and put into its own simple project, runs as expected, so I know my manifest entries/XML/Java are all as they should be. Has anyone else run into this, or perhaps can the Android team comment on what aspect of my application might be preventing the AM from starting up the process when the widget is added to the home screen?

I know it's considered taboo to place a ListView inside a scrolling container, so is there any "proper" way to accomplish scrolling of a container that has a ListView child in it? An example layout would look something like:
Header
---
"Sub" header
---
ListView with list items
---
Footer
Header and Footer need to remain static on the screen, and the middle content (Subheader and ListView) should scroll between them. I can't have just the ListView scrollable, because the subheader takes up too much space. As it is currently, the Header comes from an <include />, the Subheader contains several views including an Image and some text, and the ListView (actually part of a ViewFlipper) would contain an indeterminate number of items. The Footer has a couple buttons/tabs that are used to control the ViewFlipper (only one of the views in the flipper is a ListView).
The only way I can think of to accomplish this efficiently would be to place the Subheader inside the ListView as the first item -- is there any better way?

I have created a parent class and a child class that inherits from it. When I set the OnClickListener in the child class, the event fires when the button is clicked. When I move the set OnClickListener to the parent class, the event doesn't fire. I've got to be missing something obvious but I just don't see it.
