Is it possible to add a click event to an ImageButton? In my code its not working
Here is my code:
CODE:..................
I 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).

View 2 Replies View RelatedI 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 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).

View 1 Replies View RelatedI'm developing a small application in with a list view filled with a compound component. This component has two text view and one button inside. One of the text view is invisible and when the button is clicked it should appear. I can show the list but i can't make the textview visible when the button is clicked. Here is the xml of the component: And this is the ArrayAdapter that fills the list:

super(_context, _resource, _items);
resource = _resource;

public void onClick (View v) {
int i = placeView.findViewById(R.id.stub_import).getVisibility();
visibility(i);
} };
private void visibility(int i) {
// TODO Auto-generated method stub switch(i) {
case(View.GONE): { addressText.setVisibility(View.VISIBLE);
} case(View.VISIBLE): { addressText.setVisibility(View.GONE);

@Override public View getView(int position, View convertView, ViewGroup parent) {
Item item = getItem(position);
String name = item.getName();
String address = item.getAddress();
if (convertView == null) {
placeView = new RelativeLayout(getContext());
String inflater = Context.LAYOUT_INFLATER_SERVICE;
LayoutInflater vi = (LayoutInflater)getContext().getSystemService(inflater);
vi.inflate(resource, placeView, true);

I have a Layout with a spinner and a ListView.ListView- Each row has a text and couple of buttons. ( CustomAdapter).On click on any of those buttons, I need to know the text in that row.
Each row has a question with buttons Yes or No. On click of buttons Yes/No, I need to find the corresponding question.
I have a single screen with a bank of buttons below a ListView. Entries on the ListView light up in orange when I scroll so I assume that are selected. When I then press the "Delete" button I want the onClickListener to remove the currently selected entry. But getSelectedItemPosition() always gives me -1. If I can't hope to use the GUI controls in this way, please give me another way of getting the same result.I have even tried setting the onClickListener of the List View to store the index before the button is pressed (in case pressing the button unselects the entry) but even that is always -1 it seems.
View 1 Replies View RelatedI have the following, very simple test program for using a ListView. I create a ListView and set it as the content view. I set a ListAdapter which supplies the rows. There are 30 rows, and each row consists of a LinearLayout ViewGroup. Into that ViewGroup, I place a TextView and a Button. When I run the program, I find that I cannot select rows of the list. I can, however, scroll the list and click the button. If I remove the button from the LinearLayout (so that it contains only the TextView), then I am able to select rows of the list. I would like to be able to have buttons on my individual row views, and still be able to select rows of the list. On another forum, someone said that this was possible, but I am at a loss as to how to accomplish it.,.........................
View 1 Replies View RelatedI am essentially using a listview but am looking at providing a bookmark functionality. I am thinking that I should store the item attributes in a file when bookmarked and retrieve when required to populate a bookmark listview.
I was wondering if there is a de facto standard used in achieving this or do I follow just the "writing into a file" and "reading from a file" when necessary style?
We want to add below update sql into our content provider:We found current update of content provider does not support it, which would not recognize the "column1" of "column1 + 1" as column name. So we have to add execSQL method into ContentProvider and I think it is dirt. So I wonder if anyone know how to do such thing with ContentProvider or any more elegant way to achieve it.
View 5 Replies View RelatedMy application needs to intensively manipulate (read-write) on some structured text data.The size of the data is significant 1Mb. And there is initial data available for the user to start with.My idea is to put this data as a file in the .apk. Then, on initial application launch to read this data and populate Android SQLite database with it. Then just work with this database. But after the database is populated the data file is no longer needed. And I'd like to remove it to free some memory. Alternate approach is to work with this data file instead of SQLite database. But I assume SQLite would work a magnitude faster then i/o on my data file..

Do you have some code examples of such solutions?
I want to create an app widget that could take up a different number of "cells" on the home screen, but I don't think that the app widget framework easily supports this. I know that an app widget can have a configuration screen, and I'd like the user to be able select a sort of small, medium, or large size for the widget as part of my configuration activity. Unfortunately, I don't think that this is possible, correct? Based on the minWidth and minHeight properties, the Launcher app will assign a number of cells that I can't configure at run time.
For instance, if I want a weather widget that has a current, hourly and weekly format that take up 1, 2, and 4 cells respectively, I can't do this at run time. Instead, I believe my only option is to export 3 different widgets and have them all listed in the widget picker dialog as something like "Weather - current conditions", "Weather - hourly forcast", and "Weather - week long forcast".
