I have 3 activities in my app: Activity1 -> Activity2 -> Activity3. Inside Activity3, if the user presses Back, I would like to return to Activity2. In Activity3's onPause event, I added a finish() statement. That's probably not even necessary, but I wanted to make sure this Activity gets cleaned up. This works fine.
However, while in Activity3, if the user presses Home or starts a new app (through notification bar or some other means), I want both Activity3 and Activity2 to finish. If the user returns to this app, he should resume with Activity1.
I have figured out how to do one or the other, but I can't figure out how to handle both cases, if it's even possible. Can I trap the "Back" button in Activity3 and send a message back to Activity2 telling it not to finish()? It seems like the Activities follow the same lifecycle flow (Pause, Stop) regardless of what you do to send them to the background. Just to answer the question of why I want this behavior, imagine that Activity1 is a login screen, Activity2 is a selection screen, and Activity3 is a content screen. If I press Back from the content page, I want to be able to make a new selection. If I exit via any other means (Home, notification bar), I want the user to be "logged out".
Need an example of how to create/start a new activity from the main activity. I have a button click event on the main layout. Originally I just used setContentView(R.layout.secondactivity); which brings up the layout but I don't think that is correct since the secondactivity class is not instantiated at this point yet. I have looked for such an example and can not find one.
View 3 Replies View RelatedI have written a ListView with a text and image clubbed together in a row. I wanted to add a button on top of listview, then the entire content of listview should be seen. Button is named as "More", when someone clicks it i will be updating the listcontent. That is the main theme.
My java file.
CODE:.....
* Demonstrates how to write an efficient list adapter. The adapter used in this example binds
* to an ImageView and to a TextView for each row in the list.
*
* To work efficiently the adapter implemented here uses two techniques:
* - It reuses the convertView passed to getView() to avoid inflating View when it is not necessary
* - It uses the ViewHolder pattern to avoid calling findViewById() when it is not necessary
*
* The ViewHolder pattern consists in storing a data structure in the tag of the view returned by
* getView(). This data structures contains references to the views we want to bind data to, thus
* avoiding calls to findViewById() every time getView() is invoked.

I have a problem that some other people on this list (and other android sites) also have/had, but was unable to find a solution. I have a ListView with a custom view for the row which looks like this: <RelativeLayout><ToggleButton/><TextView/></RelativeLayout>
Its basically a list of songs that i show. What i want to achieve:
If the user clicks on the ToggleButton the song should be played. If the user clicks somewhere else on the row, the details intent of the song should be launched.
So I want to have two events on every row, event1: the button click, event2: click somewhere except on the button.
Right now i have a custom adapter where i call .setOnClickListener() on the button. Now the button works (event1 works), the song is played, but the rest of the row is not clickable (event2 does not work). If i remove the call to setOnClickListener() the row is clickable (event1 works) and the details are displayed as suppossed, but the button is not working. (event1 does not work)
There are apps out there, that have buttons in lists so this must be possible. Could someone please tell me how to have more than one click event on a lists row?
I am new to android. I would like to add two normal buttons in the List (ListView).
Could you please provide me any example of source code so that i can understand.

I want to show a button at the end of an android list view
How can I achieve this? i dont want to stick it to the activity bottom using alignparentbottom="true", layout_below does not work for me either.
But i want to show it at the end of list view

I am trying to bind a list view to a List. This works ok when I create an activity that extends ListActivity and I have a text view in my layout file (i.e. the activity is binding to the default listview in the activity). However, what I would like to do is have a ListView that contains an image button (to further perform the deeltion of the row) and the text view to illustrate the name of the item being bound.
The layout file
The activity class
I have played around and cant seem to get it to work, as soon as I add a ListView / image button to the layout file my code crashes. I've also found a few examples through google, but none seem to work!
I have an application of list view.Each row in listview contain textview. But I want to add a button on top of the list view.how I can add button on top of that listview using Java?
View 3 Replies View RelatedI created a ListView that contains a row which in turn contain text and a button. The idea is to have the button function as a delete button to remove the row from the list as well as the database. I order to do this I created an adapter to handle the button click. This code is below. Deleting the database record works fine, but I have not yet succeeded in refreshing the ListView so the record will no longer be displayed.
public class FeedArrayAdapter extends ArrayAdapter {
private ARssEReaderDBAdapter dba;
private String TAG = "FeedArrayAdapter";
private View v;
private ListView feedList;..............
Each row of my view look like that:.............
When I click on the ImageButton "arrow", I trigger a method than need the id of the row to perform. By ID I mean the value of the field "_id" of the corresponding record in database. I did not find a direct way to do it, but I think I can if I get the index of the row in the ListView. Again, I don't know how to get this index from a click to a childview.
I want to show this array as a listview in a new screen when a button is clicked.
ArrayList<String> favorite = new ArrayList<String>();
This ListView is a small part of my class. i cant seem to figure out how to implement it with my code (i can figure out how to create a listview in a separate application, and set the onitemclicklistner just for that listview) i want to display that listview when.

I have an activity with ListView and buttons below:
CODE:.................
ListView row contains delete button:
CODE:.................
In Adapter, Button onClickListener is set, also there are dummies to make list non-selectable:
CODE:..............
What I want is:
Always show buttons in the bottom of screen after list (no matter how long it is, there should be scroll if it's too long) ListView should not be selectable, I don't want row selection row delete button should be selectable (focusable) with touch and with trackball
And everything works except I can't focus row delete button with trackball (although it's working with touch).

The dividers are disappearing/appearing and flickering as i scroll the list (tested in emulator and HTC Tattoo). Strange is that the same example downloaded from the market (API Demos app) behaves correctly. Here is a screenshot of how it looks: http://yfrog.com/4cnokp.
