I want my dialog box to fill the screen as I have seekbars set on fill parent, and so it makes this tiny dialog in the middle of the screen with tiny seekbars to go along with it.

The Android Developer guidance on Creating a Custom Dialog specifies a layout that starts:
code:........
If I use this code I get a dialog that sits in the centre of the screen with about 40 pixels of the underlying view visible on each side.
What exactly does "fill_parent" mean (for the width and height)?
Consider a VideoView added to a Linear Layout with parameteres FILL_PARENT, FILL_PARENT.
The Linear Layout gets added to the root layout which is a Relative Layout, with parameters WRAP_CONTENT, WRAP_CONTENT.
Which parameters take precedence here?
I created a custom dialog that extends Dialog. One button on that the dialog is an "OK" button which the user is expected to press when finished entering information in other fields. I cannot get any listeners set to that button to fire.
public class HeightDialog extends Dialog {
private Button okButton;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.heightdialog);
this.okButton = (Button)this.findViewById(R.id.userOkWithHeight);
this.okButton.setOnClickListener(new android.view.View.OnClickListener() {................
Where can I find the preference widget that is used in the Voicemail number setting in the Android emulator? I'm implementing a feature with a very similar use case and would like to use an obviously already existing preference widget instead of creating a similar custom one by myself. The exact "path" to the setting I mean is: Settings -> Call settings -> Voicemail settings

It is posssible to set a animation to a home screen widget? Something like,if special button of the widget is clicked, the widget shows a view that breaks out of the widgets borders which are defined in the home screen widget meta-data file?
I'm sure I am missing something simple...
Background:
I am new to android and UI design, and I just wanted to play around with layouts. Right now I want to stack a checkbox on top of text label. I am using the following xml layout which works fine:
CODE:................
My Tests (just to get a feel for how things works):
Scenario 1) When I set the CheckBox's layout_height to "fill_parent", the CheckBox takes up the whole screen and is aligned center (i.e. - the TextView disappears).
Scenario 2) If I instead set the TextView's layout_height to "fill_parent", the CheckBox does NOT disappear. In fact, nothing disappears, and the layout looks the same as the above xml where everything is pushed to the top-left.
The Question (and comments): How come Scenario 1 works the way it works?
This behavior seems inconsistent to me. I thought that fill_parent is only supposed to let the element fill up whatever space is available in the parent. So to me, it seems that the TextView should get whatever space it needs (since it is wrap_content), but the CheckBox should take up the rest of the space (so the TextView would be forced to the bottom of the screen, but not invisible). In other words... Scenario 2 makes sense to me, but scenario 1 does not.
I am using a HorizontalScrollView to contain and scroll 3 child widgets, each of which is either an ImageView or a custom widget. What I'd like to achieve is something like homescreen, where each child widget filling up the whole width of the display and the user is able to switch to the other widget by flickering horizontally. I am having a hard time figuring out what properties I should assign to each of the child widget in order to have them fill the parent container. I get it working if I hard coded the width for each child but I'd like them to be able to fit to any screen resolutions, as the current Android homescreen does.
Here is the xml (pseudo like)
HorizontalView -> LinearLayout -> children widgets
This is my layout
CODE:......
When I run this the list view occupies full screen. What I want is list view to be full screen except button area without mentioning dp.
I am having this issue where I am trying to have a single TextView span one to two lines, fill the cell completely (so you can also click edges of the cell and it will trigger) and center-align.
This is the layout for the cell:
CODE:...
However cells seems to be filled correctly ONLY if it happens to wrap around and end up spanning two lines of text. It shows center-aligned and you can click anywhere in the cell to trigger the click. The cells that do not span multiple lines of text are left-aligned and trigger (highlight) only if you click where the text is. There is a "numb" area which does not react to clicks inside the cell if the text is short.
I'm currently working on a small update to a project and I'm having an issue with Relative_Layout and fill_parent in a list view. I'm trying to insert a divider between two sections in each row, much like the divider in the call log of the default dialer. I checked out the Android source code to see how they did it, but I encountered a problem when replicating their solution.
To start, here is my row item layout:
CODE:..........
The issue I'm facing is that each row has a thumbnail of varying height (ImageView01). If I set the RelativeLayout's layout_height property to fill_parent, the divider does not scale vertically to fill the row (it just remains a 1px dot). If I set layout_height to "?android:attr/listPreferredItemHeight", the divider fills the row, but the thumbnails shrink. I've done some debugging in the getView() method of the adapter, and it seems that the divider's height is not being set properly once the row has it's proper height.
Here is a portion of the getView() method:
CODE:.........
The rest of the method simply sets the appropriate text and images for the row.
Also, I create the inflater object in the adapter's constructor with: inflater = LayoutInflater.from(context);
Am I missing something essential? Or does fill_parent just not work with dynamic heights?
I have a dialog with edittext for input. when i click yes button on dialog, it will validate the input and then close dialog. However, if the input is wrong, i want to remain in the same dialog. every time no matter what input it is, the dialog always automatically close when i click button. How can i disable this. By the way, i use PositiveButton and NegativeButton for the button on dialog
View 2 Replies View RelatedI am having a problem about repeating Login dialog (an AlertDialog) and progress dialog, coordinating with http thread. I suppose repetitive Login dialog (if fail, continue) handling should be common and straightforward. I guess my approach must be wrong somewhere. I already spent 2 days on this and am desperate. So please help. User starts the app, the main activity starts.Show a login dialog (generated by the main thread, i.e. from on Create. The main thread then starts a wait_thread, which will wait for http to return data and check the data and decide what to do.After user input username/password and press login, a progress dialog starts.The progress dialog starts an http_thread to talk to the server and get replies. Once done, it will notify the waiting thread.If the user type in the right username password first time, the code works fine.But it always fail for 2nd time Login, i.e. When first login fail(wrong username/ password),the wait_thread will generate 2nd Login dialog to let user repeat the login process. But after user hit the login on this 2nd Login dialog, the system always crashes.

I'm trying to get my list view to open up an alert dialog to display information when a person clicks on a selection. I have been trying several different things on the Google Developers website that have to do with this but have yet to come up with a result. Here is my code. package table.periodic;
import android.app.Activity; import android.app.AlertDialog; import android.app.Dialog; import android.content.Context; import android.os.Bundle; import android.view.View; import android.widget.AdapterView; import android.widget.ArrayAdapter; import android.widget.ImageView; import android.widget.ListView; import android.widget.AdapterView.OnItemClickListener;...........
According to documentaion, FILL_PARENT basically lets the view take up the entire extra space. Weight also dictates how much of the extra space can be taken by the view. What is the difference? For eg: What happens when I use, new LinearLayout.Layout Params(Layout Params.WRAP_CONTENT,LayoutParams.WRAP_CONTENT, 1.0f)

I have a really weird problem, which I am unable to debug so far. thing is. my app needs to download something to work. So in the beginning of the onCreate() method, I check if that something is already downloaded. If not, I pop a dialog up asking the user to download it.My dialog is shown and I am clicking, so aManager.install() is called. I am passing the context because that aManager.install() pops up a ProgressDialog to show downloading progress and spawns a new thread in which everything is downloaded. So obviously before creating my dialog I make a Handler to receive the response from that aManager.install(). And the response MAY vary, because for example the internet connection isn't available (Exception raised and catched and listener called with different code).Now, when that happens (Exception) I would like to call another dialog saying "something went wrong, would you like to retry?" so another call to showDialog(DIALOG_REINSTALL) (this time with another code).thing is the showDialog() gets called (I can verify this by logging) but the dialogs doesn't show up. Instead my application JUST HANGS Does someone have a clue why it's doing this? No exception raised, absolutely nothing from logcat, I can't tell WHERE it's hanging...just see that the method is called and the dialog should be displayed.

I'm just getting my feet wet with Android and have built a UI that contains a TabHost with three tabs. Each tab is powered by its own Activity. The first Tab contains a listview with a prepopulated set of rows and is built from a custom ArrayAdapter.
The problem I'm running into is that none of the ListView rows are tappable. In other words, when I tap on them there is no orange selection. If I use the scroll ball on my Nexus One it will select, but any touch gestures don't seem to be responding. All the UI is being handled using XML files with a main.xml housing the TabHost -> LinearLayout -> TabWidget/FrameLayout and a nearby_activity.xml file containing my ListView UI
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"

I've created a home screen widget by extending the App Widget Provider. It works fine on all phones tested so far except Motorola's Droid 2 from Verizon. It's running Android 2.2. What I noticed is when my widget is first place onto a home screen it works for about +/- 15 seconds. Then I see the widget receives the action com.Motorola.blur.home.ACTION_WIDGET_ADDED and the widget stops responding? The buttons on the widget still show pressed or selected states but the widget code itself is no longer called?

A customer just notified me that she's experiencing the infamous "app not responding / wait, force close" message during a specific operation. By just waiting enough, the app resumes ok. Now, that specific operation is indeed long and in fact it has been programmed in a background thread, with a progress dialog signaling the wait. I can't reproduce the problem on my development phone - I suppose because it's perhaps faster than the phone of the user. But I can't reproduce the problem either with the emulator, which I suppose is slow enough. Generally speaking, I think I could be able to solve this specific problem with the customer giving me the proper feedback. It's the general issue that hassles me. This part of the application is very good covered by tests at different levels, including automated black-box tests with Robotium that drive the UI as the user would do, and even in "stress mode" (repeating the test multiple times). So I supposed to be very safe in that area and I'm disappointed to discover that it was a false sense of safety. What am I possibly missing? Also, is it possible / does make sense to "slow down" a phone during tests? I was thinking of a service running in background just consuming some CPU cycles to make the phone less responsive.

I've looked everywhere for a solution to this, but I can't figure out how to implement it. My OnItemClickListener was disabled somehow on my ListView rows, because I have an ImageButton in the row layout, which takes over the focus. There have been numerous questions I've found, but none of them have gotten me anywhere. I've checked this question, but I couldn't really make heads or tails of it. I just need a way to get the rows clickable so that I can detect when a row is pressed. Long press and focus work fine.
