Android :: Getting Information From Radio Buttons And Checkboxes
Nov 4, 2010
I have report which consists of 5 questions (there can be only one answer or multiple choice answer). Question are different for each report. So everytime I generate questions and answers as RadioButtons (one answer) or CheckBoxes (multiple choice answer)...But now I really don't know how to save those answers (I'd like to save to it as _question_id, _answer_id). How can I assign good _answer_id, to _question_id...

I currently have code that creates rows in a table that hold a string in column 1 with a RadioButton in column 2. There can be a variable number of these rows. That all works just great, but I want to add them to a RadioGroup so only one button can be toggled at a time. When I tried to add the dynamic RadioButton to the RadioGroup AFTER I added it to the table row, I got an error saying that the child (the RadioButton) already had a parent. I agree, it does have one, the TableRow.
can you have radio buttons tied to a radio group inside of a row or, should I just code my own toggle mechanism and avoid RadioGroup all together? I mean, I could code the onClick to unclick all other radio buttons, but I would rather not do this if I can use the build in RadioGroup.
<ScrollView
android:id="@+id/ScrollViewModifyGroups"
android:layout_width="fill_parent"
android:layout_height="fill_parent".............

I have multiple radio buttons which I want to layout using a table but also include them in a single radio group. I have the following xml layout:
<RadioGroup android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:id="@+id/Group1">
<TableLayout android:id="@+id/RadioButtons"
android:layout_width="wrap_content".........
But unfortunately the radio buttons inside the table seem to ignore the fact that they're inside of the RadioGroup tags and because of this you can select more than one radio button at the time. I noticed that by removing the table and just having the radio buttons it works just fine. How can I overcome this? Would it be as simple as declaring the radio group inside of the table instead of outside?

There can be a variable number of these rows so I cannot just create it in the layout xml as radio1, radio2, etc. My code displays the table with the string and RadioButton pairs just great, but I want to add them to a RadioGroup so only one button can be toggled at a time.

I would like to add radio buttons to my context menu, but I'm not sure how. This is how it is created:
@Override public void onCreateContextMenu(ContextMenu menu, View v,ContextMenuInfo menuInfo) { super.onCreateContextMenu(menu, v, menuInfo); enu.setHeaderTitle("Selection Options"); menu.add(0, v.getId(), 0, "Remove");}

In Android 1.6, upon tapping a spinner (drop-down menu), radio buttons appear next to the spinner options. How do I remove those radio buttons so that just the option text remains?

In my app I bring up a context menu on long click in a ListActivity. One of the options "Priority" pops up an AlertDialog with 3 radio button choices. The problem is, it displays an empty dialog box without my 3 choices, or the message that I set. Here is my code...
If I replace the .setSingleChoiceItems with a positive and negative button instead, it displays the buttons and the message as expected. What am I doing wrong in setting up my list of radio buttons? Here is my calling code as well...

I am a Mac user (photographer/ videographer). I also rely heavily on my iPod Touch when mobile (i can often find a wifi signal when i am out and about). I use iCal on the Touch and iCal on my Mac as well as the address book on both everyday and as a Mobile Me user, my two devices sync so everything is mirrored and up to date. I also HATE AT&T for their terrible signal strength and coverage and have been a loyal Verizon customer for many years and this is why I don't have an iPhone. Okay, all that being said, is there an easy way to still use everything I love and rely on with my Mac (the calender and address book, mainly) and easily sync all of my existing information and future info to an Android based device? How easy is it to use an Android device with a Mac? I don't want to have to manually re-enter my entire address book into a new device.

I have being playing around with expandable list views recently. I am trying to get a list view that has a checkbox as one of the elements of the child view.
I found this tutorial, http://mylifewithandroid.blogspot.com/2010/02/expandable-lists-and-check-boxes.html, and it seemed perfect. However when I compiled it and started playing with it I realised its very buggy. Checking a box in one group can cause a random box from another group to check or uncheck.,
This is the only tutorial I can find on this, It seems like a thing that would be used in a lot of apps, so I was wondering, is there any other good tutorial or resource out there that deals with this? Or even better, would anyone care to show their own code having gotten this to work...

I have a ListView, and within each list item I have some TextViews and a CheckBox. When I check a CheckBox and my onCheckedChangeListener fires, everything works as it should. However, random other checkboxes get checked once one is checked. Here is an example.
If I click on the first CheckBox:
8 is checked.
15 is checked.
21 is checked.
27 is checked.
33 is checked.
41 is checked.
Then if I scroll all the way up, none are checked until 6. The next being 13.

I want to add some checkboxes to a LinearLayout at runtime. The orientation is vertical and I want the checkboxes to appear at the bottom. I create each checkbox like this: CheckBox box = new CheckBox(this);
Then I add the box to the current view like this: addContentView( box , params ); What should be the params to get the effect I want? So far, everything I've tried ends up overlaying the new checkboxes on top of each other and on top of the other items in the layout. I want everything stacked in a column with the new checkboxes at the bottom.

Given a listview that shows checkboxes next to a list of people, I want to be able to get the names (in Strings for example) of the people who are checked. I have set my listview mode to allow for multiple checks.
getCheckedItemPositions()
Will get the positions but I can't figure out how to iterate over the listview to get the names. Also Eclipse tells me that getCheckItemIds is not a valid method for ListView.

I am facing a very mysterious Problem. I am using a ListView with CheckBoxes that can be clicked to select people. The row layout is the following:
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="wrap_content"> <CheckBox android:focusable="false" android:onClick="onSelectPerson" android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center_vertical" android:layout_marginRight="5dip" android:layout_marginLeft="5dip"/> <TextView android:id="@+id/person_name" android:text="test" android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center_vertical" android:textSize="18dip" android:layout_marginLeft="5dip"/> </LinearLayout>
As long as the amount of rows doesen't exceed the screen size (-> no scrolling) everything works just fine. But as soon as I have more rows then the screen size (-> some rows are hidden and have to be scrolled to). I have a very mysterious phenomenon: If I check the top row and scroll down some of the previously hidden rows are randomly checked too. If I scroll up again, again some of the before hidden rows are randomly vhecked (the CheckBox I clicked in first place may or may not still be checked). Also the registered onSelectPerson callback is only called for the CheckBoxes I really click. The other CheckBoxes just change their state to "checked" without calling the callback method. I have the same phenomenom on the Archos IT 5 and the Nexus One. This must have something to do with the ListView implementation but I can't quite figure out what the problem is.

I'd like to have a dialog box which prompts the user to select from various checkboxes, then confirm "Ok" or "Cancel". I have this working, but my only issue is the dialog always retains the previous checkbox selection state from the last time the dialog was shown. I'd like to always force the checkboxes to be unchecked (false) every time. Is there a way to accomplish this?............

What should I do to use custom checkboxes if I add my checkboxes dynamically in my code? (On the java code not on the XML files.) I'm following this tutorial, but using it I can't achieve my goal. For example, I have a tableLayout and I want to add a checkbox for each new row I have.
