Android :: Way To Add Buttons At Run Time To Each Row In List View?

Jul 17, 2010

I am working in an android application that uses a list view. I currently have a XML for the row layout with only one text view. Based on certain conditions, some rows will have one additional button and some other rows may have 2 additional buttons. Can I override the getView method of the adapter class to do this logic? is there any performance issue?

Android :: Multiple Buttons For List / From Which View It Was Pressed?

Aug 21, 2009

I am writing a program where I need a ListView for which I am using a ListActivity. Each one of the views within the ListView has four buttons, (Off, Dim, Bright and On). Each one of these buttons is configured with it's own OnClickListener when I build the view. This part seems to work ok. However when I have say 5 Views each which has these four buttons, I can tell whether an off, dim, bright or on button was pressed but I cannot tell from which view it was pressed. So for example if my views are devices (Light, Heater and Kettle) I press an "on" button and I know an On button was pressed but how do I get it to tell me the On button for the Light was pressed?

Android :: List View Elements With Multiple Clickable Buttons

Nov 10, 2009

I've a ListView where every element in the list contains a TextView and two different Buttons.I found a solution as described in my answer below. Now I can click/tap the button via the touch screen. However, I can't manually select it with the trackball. It always selects the whole list item and from there goes directly to the next list item ignoring the buttons, even though I set .setFocusable(true) and setClickable (true) for the buttons in getView().This causes that no list item is selectable at all any more. But it didn't help in making the nested buttons selectable.

Android :: Multi Column Custom List View / With Editable Edit Text At End Of List View

Nov 3, 2010

I am on Android 2.1 and I have one multi column Custom listview Using BaseAdapter with an editable edittext at the end of the listview. If the data in the listview do not contain the data of user choice then user should be able to enter data. If the data is already there in the list user will be able to select the data using custom selector. If a selection is made in the list view and user wanted to enter data in the text field at the bottom after selection then the marker in the list view should be unselected. I tried to use onclick() method on edit text using click listener. First time when it is clicked, edit text is getting focus and onclick() method is not fired. And when it is clicked second time, onclick() method is fired and notifyDataSetChanged() method is called. I tried to call the notifyDataSetChanged() method from the Focus Listener, list view selection is gone in my first attempt and edit text is not receiving any data input from the keyboard (frozen).

Android :: Populate View Flipper Child View With List View?

Aug 2, 2010

I am trying to set up a ViewFlipper that changes a SlidingDrawers content each time a button is pressed. So far every view I set up worked fine, but now I am trying to create a ListView (including single_choice_mode) within a child view of the ViewFlipper, but my attempt only let to a NullPointerException. As I only discovered ViewFlipper today, I am not yet familiar with it and may not have understood it completely. if someone could give me a hand and help me find out what I have done wrong, that would be great. Here is what I have done:

The code for the onClick event of the ImageButtons:
public void onClick(View v){
if (v == btnExposure){
mFlipper.setDisplayedChild(0); }
else if (v == btnProperties){
mFlipper.setDisplayedChild(1);}
else if (v == btnSpecialEffects){
mFlipper.setDisplayedChild(2);.............

Android :: Graphically Represent Multiple List Selections / Dynamically Change List Item View

Apr 23, 2010

I'm trying to create a multiple selection list where the selection is represented graphically rather than with checkboxes.My list has checkboxes, but I want them to serve a different purpose. I'm using a cursor to hold my data and created a custom view binder for the SimpleCursorAdapter. I did this for the checkboxes and general flexibility.So far I haven't even been able to show one line as being selected. I've enabled multiple selection on the list and denied the children of the list item focusability. I've tried manually changing background color with the position fed in through the list item click listener. But the wrong items get changed and they don't even change to the right color. I've enabled touch focusability with no improvement either.Ideally, I'd like the trackball highlight focus bar to appear in multiple places. But I don't think this is possible unless you use the drawable directly. But I don't know how to find or apply it. My next idea was to have a slim view bar that changes color. But I had the same problem with the wrong item being selected so I never finished trying to guess the index position to see if this would work. My most recent idea is to completely swap out the view for another one if it's selected. But I have no idea how to do this either. I'm thinking of using an array list to store the _id s of the items that need a different view to get around the wierd selection problem. I'm also thinking of passing in the ID field as my from and the selection view as the to for my adapter. Then I'd intercept it with my binder and change the view accordingly. But once again, I'm not sure how to do this successfuly.

Android :: Combining Map View And List View In Application

Aug 4, 2010

I am working on an application where I need to display some locations on a map and in a list view where the user should be able to toggle between these views(activities?). I want the toggle button(s) to be in my custom titlebar like in the images (if they are attached). What is the best practice for this? Tab view seems like a solution but can I customize the tab buttons? Should the map and list be in different activities or the same? Now I have two different activities one extending MapActivity and one extending ListActivity but no way to toggle between them. Is it possible to load activities into a FrameLayout?

Android :: How To Set All Buttons Clickable / Unclickable At Same Time Using SetClickable?

Sep 15, 2010

The screen displays four buttons. When a button is pressed, a media player plays a sound. The problem I'm having is implementing setClickable for all buttons at the same time. Once a button is clicked, I want all buttons to be unclickable until the media player is finished playing the sound associated with the button click. Then I want all buttons to be set back to clickable. The code runs fine until I enable the setClickable code--the code for buttonOne is disabled in my code sample below. The test phone locks up and tells me the application has stopped and to try again. Unfortunately, without setClickable, the user could press any button and hear any sound before the first selected sound is finished playing.

Android :: Right Way To Do Scrollable View Of Custom Buttons?

Jul 5, 2010

I've just started playing with Android in the last few days and have begun to put together a simple application. I am struggling to work out whether I'm doing things the "right" way or just making life difficult for myself.The app displays a series of connected nodes on the screen, similar to a mind-map. I want to be able to tap the nodes in order to edit them. When the map of nodes becomes larger than the screen, I need to be able to scroll on both X and Y axes as needed to see the whole map. Image of current implementation at http://ubergeek.org.uk/images/nodetest.png.Currently I don't have scrolling working, however I assume that I can do that by making the root view a ScrollView and sticking an AbsoluteLayout inside that (though it's deprecated, I wish to place objects at specific X/Y coordinates).The nodes themselves are currently each a pair of roundrects (one for the outline and one for the fill) and a drawText and are being drawn in the main activity's onDraw(). In order to make these clickable buttons I believe I need to create a custom view for the button in order to use its onClick() events. I can then create a view object for each of my nodes and add them to the AbsoluteLayout view.Does this sound like a reasonable way to do it in Android, or is this a horrible abuse of the API?
