I am trying to set a RadioButton as checked/not checked through code. It is working the first time I set it, but the second time, the code does not set the button. Here is the relevant part of my code. I have commented on the problematic part. code...

If I set a radio button to be selected on the first time, it works fine. But if I unselect it by calling
((RadioButton) findViewById(R.id.ID)).setChecked(false);
then, later even if I try to make it selected by calling setChecked(true) will not work unless the user select it from the screen.
Have any one come across this? or is it only me?code...
If the else part is executed atleast once then everything gets mess up.
When I step thro my debugger, I can see the execution goes in the correct path and setting it to true. It is getting executed only once, I checked that. And I am not resetting it back to false in any other part of the code.
How to change RadioButton size? it's too big

View 1 Replies View RelatedWhat happens to the width and height params declared in LayoutParams on configuration change? E.g. if I have an ImageView declared with,
new LinearLayout.LayoutParams(30, 40);
On Configuration Change, does the width become 40 and height 30?
Flipping between landscape and portrait is causing me a problem with dialogs that are active at the time of config change. The dialogs survive (which I think is good), but I have the problem that some of my dialogs contain dynamic content which would need to be refreshed in the dialog views. All that content disappears from the dialog views after the config change.
I thought it would be easier to do a dismissDialog() on restoration in onCreate(), letting the user press the button that shows the dialog. I successfully save and recover the dialog id, but when I attempt to dismissDialog(id) I get an IllegalArgumentException: no dialog with id 1 was ever shown via Activity$showDialog. Ok, so that doesn't work, and I still have that messed up dialog up on the screen that I want to get rid of. How can I do that? Are there any other reasonable alternatives?
My app creates and shows an AlertDialog which accepts input from the user (the user needs to type some text into an EditInput).
With the AlertDialog on screen, if the user opens up the keyboard on the device, then the app's OnCreate and OnResume methods are called and my AlertDialog promptly disappears from the screen ... not the effect I was hoping for!
I thought that perhaps I needed to override the Activity's onConfigurationChanged method, but despite having the following in my Manifest:

I want to create a ListView with a RadioButton in every row. I'm using a CursorAdapter and I'm binding it in the right way, but I cannot manage correctly the RadioButton. I want that at any moment only one RadioButton to be checked (so when I check one, I would like the one that was checked before to uncheck). Furthermore, when I put the RadioButton on the row, I cannot manage anymore the setOnItemClickListener.

I would like to insert only the numerical values if possible, any easy way to do this?
View 1 Replies View RelatedIs it possible to add a little bit of space between a RadioButton and the label while still using Android's built-in components? By default the text looks a little scrunched.
<RadioButton android:id="@+id/rb1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="My Text"/>
I've tried a couple of things:
Specifying margin and padding seem to add space around the entire element (button and text, together). That makes sense, but doesn't do what I need.
Creating a custom drawable via XML specifying images for the checked and unchecked states, then adding a few extra pixels to the right side of each image. This should work, but now you are stepping outside the default UI. (Not the end of the world, but not ideal)
Add extra whitespace to the beginning of each label. Android seems to trim a leading space character, as in " My String", but specifying unicode U+00A0, as in "u00A0My String" does the trick. This works, but it seems kinda dirty.
Any better solutions?
I have two activities or "screens".
The second activity has an AlertDialogBox with radiobuttons for selecting a single option.
I want that after an option has been selected from the second activity's DialogBox, it should be displayed on the first activity screen in a text-view.
That is, suppose the user chooses "Green" from the dialogbox in the second activity, then "Green" should be displayed on the first activity screen.
Whats the way to pass a radiobuttonvalue to the textview?
I have a RadioGroup inside of a RelativeLayout. I've got a few RadioButtons for different options, like "Bob", "Joe", and "Fred". However, I need to add an "Other..." option with an EditText right next to a RadioButton in case a user wants to enter "Steve". Is there a way to do this?

Android:background doesn't seem to be the right property, the radio button image gets stretched and placed in the background of the radio button itself and its label.

I have a ListView, which is in singleChoice mode. All I want is to display a RadioButton to the side, that when clicked highlights to say it is selected, and when a different one is clicked that one goes back to unselected and the new one becomes selected. Why is this so hard? This should not be this complicated. I've spent DAYS looking for an appropriate answer to this and I have found nothing, so I'm asking hopefully in a clear and concise manner.
My layout for the listview (R.layout.view_orders):
CODE:.............
My custom row (R.layout.orders_row):
CODE:.................
My onCreate() method:
CODE:.................
Now everything underlying works as expected, you click on a radiobutton and through it's tag I can appropriately select that item from the list and manipulate it how I want. However, when the first radio button is clicked, the last one will be selected. Click that same radio button again, and it is now selected as well. Click it once more and nothing happens, both the last and the first are selected. Now I click any other one on the list, it gets selected like expected. Click anyone of the selected radio buttons and nothing happens, the radio button remains selected.
I have tried using the following in onCreate():
CODE:.................
And that just shows no radio buttons at all. AWESOME.
Now maybe (read: most likely), I'm just dense and can't figure this out, but I've seen this question asked a lot with no real answer. Lots of references to other tutorials or to the Commonsware guy's book. However, the comments are old now and his repository has changed so much, that those are no longer correct answers.
So, does anyone have any idea how to get the expected functionality out of this? Or failing that, just pass me along the GMail app's source code.

If google are reading this could you fix it? Also your ADC2 rules are unfair. Just for your information.

View 4 Replies View RelatedI have the following XML code:.................
The idea is to change the views, whenever I press one of the radio buttons. When I press a button the first time everything works out fine, but the second time I press a button, I get an IllegalStateException, and I can't quite see why I'm getting this.
Also, the Activity seems to set all my global variables to null, which is why I have to create them every time I switch from portrait to landscape or vice versa. So I would like to know if there is a way I can save my views in the Bundle, or any other way in which I can permanently save my views, so I don't have to add or create them every time, I flip the phone. And whenever I flip the phone, it seems that it rereads the main XML file, causing the RadioGroup to be set to 2D even if the 3D button is checked. This is because I've said the 2D button to be checked from when the app is first created, but I would like to also save the state of that RadioGroup.
