My app connects to the net and populates a ListView. Sometimes nothing will be returned. What is the best way to notify the user the list is empty?
For some reason the empty view (TextView in this case) always appears, even when the List is not empty. I thought the ListView would automatically detect when to show the empty view.How can I hook up the empty view properly?

However, my empty list view consist only of the ImageView listed first inside the nested LinearLayout.
This seems like a reasonable thing to do but I don't completely understand Android's layout rules yet.
I'm developing an Android application.Is there any way to show a message on a ListView only with it's empty?I'm using a custom ArrayAdapter, so I have to create a specific object with the text I want to show.I'm wondering if there is a specific field on ListView to setup a message when it's empty.
View 1 Replies View RelatedI have a ListView that with alphabetical headers for each letter. I also have an index function that brings the letter headers to the top of the screen.
My problem is when I reach the end of the list setSelection is unable to bring the last few headers to the top because it will not scroll past the end of the list.
My question is this: Is there a way to add a blank space to the end of the screen dependent on screen size? I would like to scroll until the last item in the list is at the top of the listView.

View 1 Replies View RelatedCurrently I'm trying to find an efficient way to handle the following scenario. Please comment on my current implementations and all feedback is greatly appreciated! I have about 7 adapters with data. This data comes from database and some come from xml queries over the internet which are kept static in memory. In my current implementation I re-use one ListView constantly to display this data as requested by the user. Here are the questions: 1. Is this a proper approach? or should I have a ListView for every Adapter?

This should be a simple question because I couldn't get the answer from Google . I have ListView in a LinearLayout . I need to handle the click event to allow user click on the LinearLayout to trigger some function. I try to add onClickListener to the LinearLayout , and it works only when I click outside of the ListView . How do I let the click event on ListView propagate automatically to be handled by the Listener of the LinearLayout?

View 1 Replies View RelatedHow can I empty the logcat buffer in Android? I use adb logcat from command line and pipe the output to a file, since the DDMS has a very limited buffer. At the moment, when I restart my app (after fixing bugs etc) the logcat buffer has data from the previous launch as well. Even uninstalling the app does not clear the buffer. The only way I've found so far to clear the buffer, is reboot. This is effective, but would like to know if there's an easier way.

View 2 Replies View RelatedThere 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 3 Replies View RelatedIf I create a new arraylist of size 5...
And then I try to add to the middle of that arraylist...orderedPlayers.add(2, P);
I get an indexoutofbounds...I also get indexoutofbounds if I use set instead of add...orderedPlayers.set(2, P);
In fact the only way I can add P to the arraylist is if I use the 0 index...orderedPlayers.add(0, P);
And also for some strange reason when I do that my debugger in eclipse sees that element added to the 4th index of orderedPlayers instead of the 0th... is ArrayList buggy or am I completely missing something? how would I add to the middle of a null ArrayList?
I have a problem with creating a trace file containing logs on my app. I use Debug.startMethodTracing("tracing"); and in my onDestroy() method i stop the methodTracing. Everything is going fine, like my file is created on my phone BUT it is empty, and i don't get why because it worked once and since i can't get it working. Here is the log ive got, and it says that it is writting on the file, so this is acting a bit weird. Code...
View 3 Replies View RelatedI have a Spinner whose items comes from an ArrayAdaper, and I want the Spinner to initially show that no item has been selected. When the user clicks on the Spinner it's DropDownView should display just those items available for selection.
I don't want to add an empty/blank item at the head of my list of items because that means that it shows as an avalaible selection in the DropDownView and looks pretty lame. And if a selection is made I want it to be a valid one.
I tried spinner#setSelection(-1); but that doesn't work. The first item remains selected.
I tried setting no Adapter initially (which provides the desired initial view) and had hoped to configure the appropriate adapter in the OnClickListener, but spinner#setOnClickListener throw a RuntimeException saying "You probably want to use #setOnItemClickListener instead". And trying to use #setOnItemClickListener throws a RuntimeException saying it is not valid for a Spinner.
Surely this is a common use case. How can I set the Spinner to initially show as empty?
Creating a Drawable that is completely empty seems like a common need, as a place holder, initial state, etc., but there doesn't seem to be a good way to do this... at least in XML. Several places refer to the system resource @android:drawable/empty but as far as I can tell (i.e., it's not in the reference docs, and aapt chokes saying that it can't find the resource) this doesn't exist. Is there a general way of referencing an empty Drawable, or do you end up creating a fake empty PNG for each project?
View 4 Replies View RelatedI have an android phone Jelly Bean 4.1.2
I already installed the drivers of my phone to my computer, when i plugged the cable i enable USB DEBUGGING.
After that i checked device manager and my phone is listed under Android Phone
After that i go the console and type adb devices it starts the server and returns an empty list
I tried everything. I also try kill-server and start-server still the same.
I'm using the android.location.Geocoder for the first time. The Idea is: I have a Listener on a button which takes input from an EditText and resolve the location. Up to now it's debugging phase, so I have no handler taking messages from the thread, only geocoding and write to logcat.
Q: Why this method always returns an empty list of Address objects?

I have brought over an unlocked G1 phone from the US that I'd like to activate without a SIM card. I've added the necessary entries in the android rules file /etc/udev/rules.d/ (I'm using Ubuntu Hardy). Now the G1 is recognized by the OS as an external USB drive, but 'adb devices' returns an empty list. Is there an instruction page somewhere for this?
View 2 Replies View RelatedI'm developing an Android app which needs to perform an HTTPPost to get a token back. Then use that token for subsequent calls. When I perform the initial call to get the token, it throws an exception: org.apache.http.auth.MalformedChallengeException: Authentication challenge is empty
Here is my code:...............
I googled "Authentication challenge is empty", and one this website: http://fmpwizard-scala.posterous.com/using-apache-httpclient-authenti... he had a similar problem. He determined that his web server requires preemptive authentication. Which I believe ours does too. I tried implementing what he did, and still, no dice.
I've hard coded the token in other requests, and I am able to perform HTTPGet calls.
What is the Authentication Challenge that I'm missing?
