Android :: Can't Set Checkbox State In OnPrepareDialog
Nov 6, 2010
I've got a dialog which shows a list of checkboxes. The info which boxes should be checked each time it opens comes from an edittext. I searched for a way to not allow caching of the dialog but couldn't find out how to do that. Now I override onPrepareDialog to set the checkboxes before the dialog opens. I deleted the content of my edittext, opened the dialog and there were still the same boxes checked... how to reset the checkboxes?

I have come across some very unexpected (and incredibly frustrating) functionality while trying to restore the state of a list of CheckBoxes after a screen rotation. I figured I first would try to give a textual explanation without the code, in case someone is able to determine a solution without all the gory details. If anyone needs more details I can post the code.
I have a scrolling list of complex Views that contain CheckBoxes. I have been unsuccessful in restoring the state of these check boxes after a screen rotation. I have implemented onSaveInstanceState and have successfully transfered the list of selected check boxes to the onCreate method. This is handled by passing a long[] of database ids to the Bundle.
In onCreate() I check the Bundle for the array of ids. If the array is there I use it to determine which check boxes to check when the list is being built. I have created a number of test methods and have confirmed that the check boxes are being set correctly, based on the id array. As a last check I am checking the states of all check boxes at the very end of onCreate(). Everything looks good... unless I rotate the screen.
When I rotate the screen, one of two things happens: 1) If any number of the check boxes are selected, except for the last one, all check boxes are off after a rotation. 2) If the last check box is checked before rotation, then all check boxes are checked after rotation.
Like I said, I check the state of the boxes at the very end of my onCreate(). The thing is, the state of the boxes at the end of onCreate is correct based on what I selected before the rotation. However, the state of the boxes on the screen does not reflect this.
In addition, I have implemented each check box's setOnCheckChangedListener() and I have confirmed that my check boxes' state's are being altered after my onCreate method returns.
Why would the state of my check boxes change after my onCreate method returns?
I have been trying to degub this for a couple days now. After I found that my check boxes were apparently changing somewhere outside my own code I figured it was time to ask around.

In my android app, I have a preferenceScreen with some checkboxes defined in a xml file and a class that implements "SharedPreferences.OnSharedPreferenceChangeListener". What I want to do is to select a checkbox and all the others to be selected as well. In the above listener I am able to modify the other checkboxes's state to selected, but my view remains unchanged. What should/could I do to achieve this ?

I cant find a way to save the checkbox state when using a Cursor adapter. Everything else works fine but if i click on a checkbox it is repeated when it is recycled. Ive seen examples using array adapters but because of my lack of experience im finding it hard to translate it into using a cursor adapter. Could someone give me an example of how to go about it.code...

My application has a ListView displaying some items that are associated with different documents:
CODE:..........
The ListView implements an OnItemLongClickListener and displays the available document types as follows:
CODE:...............
I would like to modify onPrepareDialog to filter the dialog to display only the document types relevant for the long clicked item (like a context menu except that some long clicks will perform a different task: expand or collapse the hierarchy displayed in the custom ListView). For example, if an item is long clicked that is associated with only document types A and B, I would like the dialog to avoid displaying document types C and D as dialog items? However, looking at R.java, it is not clear to me what the id of an individual item in the select_doc_dialog_items array would be.
How to use onPrepareDialog() to filter displayed dialog items?

I have a compound UI component built up from a ViewGroup containing a number of TextView, ImageView etc. components. Many of these have StateListDrawables as their images/backgrounds. Is there any way of making them select from this drawable based on the state of the parent ViewGroup rather than the component itself? Ideally I want to be able to change the visual state of all children of the ViewGroup (text colour, image etc) based on the state of the ViewGroup, preferably without having to hook up complex logical code. This seems like a fairly common sort of requirement, so I was hoping it would be straightforward in Android - am I going to be disappointed?

I'm a little confused by what I'm seeing with regards to phone state transitions via the PhoneStateListener. When I receive a call, this is what happens: (call comes in) RINGING -> IDLE (I pick up) OFFHOOK (I hang up) IDLE It's that first transition from RINGING to IDLE without any interaction from me (not ending the call, not answering the call) that confuses me. Do I really have to implement an idle counter to know that an incoming call has really ended? Seems like the reported phone state represents some sort of phone state that isn't the obvious one.Is this a bug or am I just not in tune with the paradigm here?

I have a horizontal LinearLayout. This LinearLayout has a checkbox next to another LinearLayout. The layout width/height of the checkbox is wrap_content, whereas the inner LinearLayout is fill_parent/wrap_content. The layout_weight of the inner LinearLayout is set to 1.
I've tried to add some android:padding around the checkbox to give some space around it, but no padding is given. I've also tried android:paddingLeft/Right/etc. How do I get some padding around my checkbox?
Note: I have an inner LinearLayout because I will be adding more TextViews
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="?android:attr/listPreferredItemHeight">
<CheckBox
android:id="@+id/mycheck"
android:text=""
android:layout_width="30dip"
android:layout_height="wrap_content"
android:gravity="center_vertical"
android:focusable="false"
android:background="@drawable/checkbox_background"
android:button="@drawable/checkbox"
/>
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_weight="1"
android:layout_height="wrap_content">
<TextView
android:id="@+id/mytext"
android:layout_width="fill_parent"
android:layout_weight="1"
android:gravity="center_vertical"
android:layout_height="wrap_content"
android:lines="1"
android:textColor="@color/white"
android:textSize="10sp"
android:textStyle="italic"/>
</LinearLayout>

I have simple list to be filled in from the database along with a checkbox. I need a handle to all the checkboxes selected. Whn the CLEAR button is pressed at that point I need the row ids of all the selected check boxes to delete them. To do this :
My list.xml file looks like this :
CODE:......
and my data_entry.xml looks like this:
CODE:............
Now: I have list.java file where I am populating the list as follows:
CODE:.....................
Now where do i give the handle to the heckbox cause anywhere else it would give me a null exception as the data_entry contains the checkboxes. Plus I need a listener to handle the checkbox status?

How can I have a checkbox in my ui alter my ui live? For example, if the box is unchecked I want a spinner to be displayed, and if the box is checked I want a text box to be displayed in place of the spinner. I know how to create the checkbox and check its status but I don't know how to hide and reveal other elements in an activity.

I kind of have a 2 part question here.
1) How can I populate my ListView so that strings are what is displayed, but when items are selected, a non-visible id value (contact id from phone contacts) is the value that is actually used?
2) I have a ListView that's using multipleChoice mode for item selections. It's popluated with names from my contacts list. When I select an item in the ListView, I want that selected item to trigger a call to my SqLite routine to store the value into a database record. How do I make this event fire when an item is checked in the listview?I had hoped to be able to use something like the onClick event for each checked item, but have made not one bit of progress.

I have a ListView with 5 items. Each of the items can be long pressed to open a Context Menu. The Menu has 5 options and I want them to be selectable, by having a check box. I know of the multiple choice listview but was not sure how to have this checkbox feature in a ContextMenu.Does anyone know if this is possible and if so, how?
