I'm using a mixture of the "Efficient Adapter" and the EndlessAdapter from CommonsGuy, and sometime the holder in getView() is null.
CODE:.............
I've put the rest of the code for both of my classes here, as it's rather large to paste inline.
Once the whole data set is loaded, scrolling up & down causes rows to disappear and re-appear too.

I want to create a layout in such a way that on top edittext and button should be there in one row. The search text I enter in editext and click on search button. Then I want to display a custom list view where each row contains image and text.(As per the API demos example list14 I have tried). But when I run the application, button and edittext are being added to each row (i.e., Each row contains a image, text, editext, button.
Below is my xml file:
<!--
<FrameLayout android:layout_width="wrap_content"
android:layout_height="0dip" android:layout_weight="1"></FrameLayout>
-->
<ImageView android:id="@+id/icon" android:layout_width="48dip"
android:layout_height="48dip" />
<TextView android:id="@+id/text" android:layout_gravity="center_vertical"
android:layout_width="0dip" android:layout_weight="1.0"
android:layout_height="wrap_content" />
<!--
<EditText android:layout_width="wrap_content"
android:layout_height="wrap_content" android:id="@+id/prdsearchtb"
android:text="@string/tb_prd_search_lbl"></EditText>
-->
<!--
<TableLayout android:id="@+id/TableLayout01"
android:layout_width="fill_parent"
android:layout_height="wrap_content"> <TableRow>
-->
<Button android:id="@+id/prdsrcbutton" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:text="@string/btn_lbl_prd_search"
android:layout_x="2px" android:layout_y="410px"></Button>
<!-- </TableRow>
</TableLayout>
-->

Is there anyway to make the incredible stop notifications for new email and sms messages without stopping it from ringing? I am a new user and am used to the blackberry setup that would vibrate those notifications in the holder but still allow the phone to ring. I figure there has to be an app for this but can't find it.
View 1 Replies View RelatedI've been looking for a solution for using my Desire for GPS tracking on my mountain bike for a while now and ideally I'd like an armband holder of some sort. Problem is, all the ones I've seen are basically clear cases that advertise the fact you have an expensive phone on your arm. I don't really want a handlebar mount cos my riding gets pretty rough so is there something that isn't either of these that anyone has found?

In my app I am drawing bus routes on top of a MapView. The routes have anywhere between a dozen and a few hundred GPS coordinates that describe the route that the bus takes. The problem I'm having is that once I draw out all these lines panning/zooming the MapView is incredibly slow (even clicking the 'Back' button takes a minute to happen). I'm not sure how relevant it is, but I put in some debug code then checked the logcat output and the MapView is repeatedly calling the draw() method of the Overlay whether anything has changed or not. This is happening several times a second and is causing a massive amount of garbage collection to happen (2-3 MB every second).

1) I was trying to draw poly lines ( I have encoded polylines, but have managed to decoded those) that move when I move the map(the only solution that I found was for Geopoints to be transformed into screen co-ordinateswhich wont move if I move the map !)
2) I have used helloItemizedOverlay to add about 150 markers and it gets very very slow.any idea what to do ? I was thinking about threads(handler)
3) I was looking for some sort of a timer function that executes a given function, say, every 1 minute or so.
4) I was also looking for ways to clear the Google map from all the markers/lines etc
My application requires that when a snapshot is taken it must store in memory and next time when I restart the phone I must get a thumbnail of that photo in list of photos and the full scale photo when I click on it.There are 2 ways I know.
1. Store images directly. Concern here is every time it has to hit directory to get image which takes some time.
2. Store all images in single xml. Concern here is XML will be too big and takes time to parse.

View 2 Replies View RelatedI have some image names stored in a database, but the images themselves are in the /res/drawable folder of the application. I need to assign these images to some views at runtime, and I'm currently doing it this way:
// public static final String DRAWABLES_PATH = ":drawable/";
int resId = getResources().getIdentifier(packageName+DRAWABLES_PATH +imageName,null,null); mButtonX.setBackgroundResource(resId); //
Is there a more efficient way to do it? Or should I be storing the images directly in the database (they are many)?

View 8 Replies View RelatedCurrently I'm using a HashMap to map the strings to int and the int values need to be frequently accessed. I'm looking for a better way to do this if possible with minimal object creation, and preferable being able to store the values as primitive ints without wrapping them with the Integer class. (Basically, the reverse of the SparseArray's int->object mapping.)

I currently have a Service in Android that is a sample VOIP client so it listens out for SIP messages and if it recieves one it starts up an Activity screen with UI components. Then the following SIP messages determine what the Activity is to display on the screen.
For example if its an incoming call it will display Answer or Reject or an outgoing call it will show a dialling screen. At the minute I use Intents to let the Activity know what state it should display. An example is as follows:
Intent i = new Intent();
i.setAction(SIPEngine.SIP_TRYING_INTENT);
i.putExtra("com.net.INCOMING", true);
sendBroadcast(i);
Intent x = new Intent();
x.setAction(CallManager.SIP_INCOMING_CALL_INTENT);
sendBroadcast(x);
Log.d("INTENT SENT", "INTENT SENT INCOMING CALL AFTER PROCESSINVITE");
So the activity will have a broadcast reciever registered for these intents and will switch its state according to the last intent it received...............
Firstly just wanted to say how useful this forum has been in keeping up to date with all the latest goings on for my HTC Hero (well, T-Mobile G2 in my case). Anyway. I'm having some problems with the speaker on my phone, the one you hold to your ear, rather than the one that plays music, loud speaker etc. I think I've found a solution, so wanted to share that with you guys, but also find out if anyone else has had a similar problem.
My phone has started crackling a lot when making calls. Other people can hear me fine, but their voice seems to crackle and fizz if it gets too loud. If I turn the volume up on my phone it gets even worse. At first I thought it was a blown speaker or something, but looking at the sim card holder, it seems to be that that's causing a rattle, it gets vibrated when the sound comes through the speaker. When I tap the back of my phone, gently!, it makes a slight rattling sound. I can eliminate the problem entirely by taking the back off the phone and firmly holding the top of the battery, thus stopping the sim card holder rattling around. However this isn't an ideal solution for everyday use!

View 4 Replies View RelatedI am doing a project where I have too develop an application that listens for incoming events by a service. The device that has to listen too events is an Android phone with Android SDK 1.5 on it. Currently the services that call events only implement communication trough UDP or TCP sockets. I can solve my problem by setting up a ServerSocket, but i doubt that's the most power efficient way. This application will be running most of the time, with Wi-Fi on, and I'd like too reach an long battery duration. I've been looking for options on the internet for my question for a while but i couldn't get a real answer.What is the most efficient way too listen to incoming events? Should I make an ServerSocket? or what are my options?Are there any other implementations that are more power efficient?
View 1 Replies View RelatedIn my android app i need to get 50,000 database entry(text) and compare them with a value when the activity started(in onCreate()).I am doing this with the simplest way : i get the whole table from db to a cursor.However this way is too laggy.Are there any other way to do it more effective?The app is "scrabble solver" that is why i am not using WHERE close in my query (Take the whole data annd compare it with combination of the input letters).At first i was using a big table which contains whole possible words.Now i am using 26 tables.This reduced the lag and i am making database call on a thread that solved a lot problems too.It is still little bit laggy but much better.
View 4 Replies View Relatedon softkeyboard, which one is better to give user a visual feedback during keypress:
1.redraw portion of button that was pressed to background canvas of main View to give pressed effect
2.each button has its own "pressed" View, and that View is set to visible (flashing) during keypress event (so no redraw needed but need more memory)
I know its trade-off between speed and memory usage, but I just want to know what you will do under this situation.
I'm pretty new to java programming and am looking to do basic data mappings.What I want to happen is when you click an item it goes to it's subcategory.I'm not worried about switching the data when an item is clicked. I'm just not sure how to create the data set in an efficient way using Android.Eventually this will be driven by a database but I want to figure out how to use mock-data to get this working first.I'd like to be able to access it like myData['category2'] or myData['category2']['subcategory3']Should I create this in xml files and link them up or is it best to create a new class structure for it?
