I'm looking to create a listview screen similar to the Sound Setting screen (in the built in Settings app, see image below), i.e I want some rows to have text + checkboxes, other rows to have text + "pop up" buttons, some rows should have text only etc.What is the best way to accomplish this?

There must be a way to do this. How can you tell a ListView that has a header to not scroll it when the user scrolls the contents? I want it to stay in a "stuck" position so that the user can always see what column the content applies to.
View 9 Replies View RelatedI have some problems when creating a ListActivity.
I have a listview and some other widgets and my listview is filled with a custom adapter.
You can see the images of this activity here:

Now the problem is. I have a scrollview and all the other views and widgets are placed inside of it. As you can see on the image, I don't see all of my 6 comments (that is the list). When i don't place the scrollview the height of the list is perfect (i have set android:layout_height to wrap_content (to my listview and parent LinearLayout). This is perfect but I have other widgets under the list and when the list reaches the bottom of the screen I can't to scroll to view my other widgets..
How can I fix this? I can set the height of the linearlayout manually but the problem is that the height doesnt has to be the same all the time (it loads the commens from my web service).. It has to fit the height of all the comments (like wrap_content normally does..)
Here is a part of the code with the layout and listview..

so far I have made a list view with text, and I am not extending list Activity, but I am extending Activity only.please if someone can provide me with a code for this.
I have added a menu to ListView Activity and wanted to allow the user to select the information that would be displayed in the ListView. So for example:
The ListView is populated in the onCreate method.
The user selects an option in the menu.
Upon the user making this selection the ListView would be populated with a different array.
Is onResume() executed after the menu is closed? I would test this but I am not currently home.
I have a fairly complex activity the parent being a linearlayout with a table with some basic info and buttons. Then a couple listviews that the user can add items to. So these listviews grow more and more as the user uses the app. The problem I'm running into is the Linearlayout is bigger then the resolution of the screen and so it needs to scroll. So the scrolling doesn't work on the Listviews. I've tried playing with changing the layout_height of the listview and its child element with no success. Is there a way to make these couple listviews expand out to the amount of children? Or am I going about this all wrong? If so what other controls can I use?
View 1 Replies View RelatedI am using this following code which creates a ListView with text and an icon but the problem that I have which the following I want the array to be dynamic instead of static so my list gets created dynamically not statistically. My ultimate goal is to retrieve specific strings from my Db and to display it then on the Listview where every string would be in each row.
View 1 Replies View RelatedI have a ListView in my android activity. And I populate the ListView by sub-class the BaseAdaptor (which returns a View in getView() method).
What if in my click listener of a button in a list item view, I change the text of the TextView in the List item view or change the dimension of the list item view by adding/removing children of the list item view
What is an efficient to refresh my listView? I don't want the listView to re-trigger a query since there is no data change.
I've a ListView with items containing information about places with a rating and the distance to the current location.
The items are sorted into groups:
Group 1: within 500m
Group 2: 500m - 1km
Group 3: 1km - 1.5km
Withing these groups the items are sorted by their rating.Now I put out these items via my custom adapter (extension of BaseAdapter) into the ListView, which works perfectly.
However, what I'd like to do is to put a separator before the each first item of each group. This separator can be a TextView saying e.g. 500m - 1km followed by all the ListView items in that group. Any idea on how to realize this?
I'm trying to copy the content of a certain row in a listview, so I can change it and later reload that row content.I've tried defining a new LinearLayout and then getChildAt(), but it's working. Is there some sort of clone or copy that I'm missing?
View 1 Replies View RelatedI have a list view which uses a custom adapter in order to show my custom content. Its layout is the following.
CODE:...............
I would like that the listview only showed the view with the ids itemimage and item description, keeping the itemtext hidden.
The idea is to have an onclicklistener on each item of the list, in order to expand that item so it shows the itemtext content. I know I should use Tweening animation in order to expand/collapse each item, but I can't figure out how to do that.
I have a ListView displaying images on every element of the ListView, It works fine... but when I start to scrolling I have realized my image is downloaded again if it is displayed in the screen of my phone device!
How could I stop reloading the images or all the content of the in ListView again?
Or how could I avoid reading the getView() function again If I have already downloaded all its content?
I have a rather complex ListView, with variable list item heights. Under certain conditions, I need to display an additional view in a list item, which is hidden by default (View.GONE). By enabling it (View.VISIBLE), the list item grows in height (or at least it's supposed to).
The problem:
Even though I declare the item's root layout to wrap_content, and each component in the item to fill_parent, the view I hide/show which is supposed to change the item's height is simply cut off at the bottom instead of its parent (the item layout) growing in height to fully display it.
Are there any gotchas related to ListViews and item layouts and item height which I may have missed?
Some more observations:
For testing purposes I have now reduced the list item layout to just contain the root LinearLayout and an ImageView. When I set the LinearLayout height to e.g. 200dip and the ImageView to fill_parent, I would have expected the ImageView to grow until it hits the 200dip limit set by its parent.
However, the image will instead be only ever as tall as its bitmap resource (as if I had set it to wrap_content) and the whole list item will be of the same height (i.e. as if I had set it to wrap_content, too).
If however I set the image height to e.g. 200dip, then the list item will grow in height, and so will the item layout.
In other words, the layout_height of the list item layout is completely ignored, and so is any height value on ImageView other than a hard-coded pixel value.
I'm trying to create an icon/widget (1 cell x 1 cell) that can be placed on the home screen of android. The widget will look and act exactly like the other standard shortcuts in android. It will have an icon and under that a label, it will be selectable with the trackball (highlight able) it will be highlighted when it is selected / clicked. How do I go about creating this home screen widget? Do I have to create the widget myself using code/xml or is there some standard xml, style, theme, code that I can use to ensure that the widget will have the same style/theme as the other home screen widgets? I currently have the following.....

View 5 Replies View RelatedMy app has one activity and one ContentProvider, the activity is simple in that it's just a splash screen at the moment with no other logic in it (I do intend to have more activities in the app). The ContentProvider uses SQLite as a back end and loads some static data from files on first install, a slow process due to file sizes and database initialization. My problem is that I want the activity to show up as soon as the install starts and maybe display a progress bar or dialog to show the user progress about the install. At the moment I get a blank (white) screen while the ContentProvider is initialising the data which takes quite a long time and I get "Activity idle timeout for history record" warning in LogCat. My splash screen only shows when the Content Provider is done, from the app standpoint this is undesirable behaviour. One potential solutions would be to manually start the provider via an AsyncTask but I have a feeling that this is a bad approach due to the fact that if the activity is interupted and restarted while the install is underway and a new AsyncTast is created through the activity's onCreate() then I'll have worst problems on my hands. Is there a way to start the content provider in the background and display my splash screen activity straight after the app is started? Note that this problem is only an issue on first install.

Step 1: I am subclassing WebView and rendering html content properly. The intial content is very small with a div and image /link This is displayed in a LInear Layout along with a TextView and ListView. That is my first screen/activity of the application.
Step 2: When I click on a link on this webview, it goes through the webViewclient and expands to full screen to fit the content of the requested page.
After Step 2, I am not able to go back to my activity screen once the content is displayed. When I click on the back button to getback to my activity screen close my activity and goes to the phone's applications desktop. (i.e goes out of my application).
Step 3: In order to fix this issue, I stopped setting my own subclasssed WebViewClient. After doing this, the it seems to render the clicked page in a webView as subactivity. Now When I click on backbutton, it goes back to the activity screen. But, the issue now is, I am not catch event when a link is clicked. How can I catch click events in this case.

Is it possible to create a shortcut for network preferences in home screen
As i use that option frequently, each time i have to go to settings-->more-->mobile networks-->Network preferences
I have the beginnings of an app that will eventually comprise of three screens. I want to allow the user to move through the screens by flicking the current screen.
The screens should be positioned horizontally: 1 - 2 - 3
So, a flick from right to left should move from 1 to 2, a flick from left to right should move from 3 to 2 and 2 should be able to move to pages 1 and 3 respectively.I believe this is called SwipeView but cannot find any clear instructions on how to implement this.
This may seem like a stupid question but I need to be sure. I was wondering if it was possible to pro-grammatically change the Content Provider used when making a query given a Content URI. The reason being I need to know if it's possible to force the Calendar/Contacts applications to read from a different database via a different Content Provider temporarily while my application is running, so that I can reuse those applications to display my own data. Since the Content URI s are hard coded in each of these applications the only way it might be possible is if we could somehow temporarily change the Content Provider used for a given URI. I know this probably isn't possible, I just need to show it isn't. Could someone confirm this can't be done?
View 2 Replies View Relatedin some apps (such as VLC, Flash player, the stock video player, etc), there appears to be a small black bar at the bottom where the status bar usually is (even if it's hidden, there's still a black bar). I've had a research and saw a solution app called 'full!screen', however I have no way of rooting the device (It's an Android TV box with no USB output, only input). My current solution is to use MX Player, but it doesn't play 1080p videos properly, so I'd really prefer VLC at this point.
