View 1 Replies View RelatedI am on Android 2.1 and I have one multi column Custom listview Using BaseAdapter with an editable edittext at the end of the listview. If the data in the listview do not contain the data of user choice then user should be able to enter data. If the data is already there in the list user will be able to select the data using custom selector. If a selection is made in the list view and user wanted to enter data in the text field at the bottom after selection then the marker in the list view should be unselected. I tried to use onclick() method on edit text using click listener. First time when it is clicked, edit text is getting focus and onclick() method is not fired. And when it is clicked second time, onclick() method is fired and notifyDataSetChanged() method is called. I tried to call the notifyDataSetChanged() method from the Focus Listener, list view selection is gone in my first attempt and edit text is not receiving any data input from the keyboard (frozen).

I have two ArrayAdapter<String> to handle the values. I have issue in the display. my xml file is structured as
<Linear Layout>
<ListView> </ListView>
<ListView> </ListView>
<Linear Layout>
its displays the two list items by dividing the screen into two equal parts and scrolls within the list individually.
I wanted the List 1 to be displayed fully and then followed by List 2 and also it should screen should be scroll not with in the list but full screen so that List 2 could be seen below.
i tired many ways but still the results are not fine.
I am having trouble passing a List type from a remote service to the UI activity. Here is a modified version of RemoteService example from the APIDemo. (only included where its modified)
PROBLEM: The call back function (for List) is called successfully, but the List returned is empty...
It works fine when the service does not run in a remote process. (w/o android:process=":remote" in the manifest file)
Why is this happening...?
Also, when I tried Map type, it didn't even successfully generate a IRemoteServiceCallback.java file.... it tries to do new Map().... and complains that its an abstract class.. (FYI, List instantiates by new ArrayList())
1. in IRemoteServiceCallback.java oneway interface IRemoteServiceCallback { /*** Called when the service has a new value for you. */void valueChanged(int value); void valueChangedList(out List values); void valueString(String value);}
I'd like to show another List View 'B' after clicking a item of List View 'A'. I use onListItemClick event in Android 1.6 project.

View 13 Replies View RelatedI created the following method for retrieving stored settings from the database:
public String getEntry(long rowIndex){
String value = "";
Cursor c = db.query(DATABASE_TABLE, new String[] {KEY_NAME, VALUE}, KEY_NAME + "=" + rowIndex, null, null, null, null);
int columnIndex = c.getColumnIndex(VALUE);
int rowsCount = c.getCount();
if(rowsCount > 0){
String value = c.getString(columnIndex);
}
return value;
}
On debugging I can see cursor c contains two columns and one row but when it comes to line
String value = c.getString(columnIndex);
it throws the CursorIndexOutOfBoundsException although columnIndex = 1 which should point to a valid entry. Does anyone know what could be wrong here?
For changing from portrait to landscape mode i have done some changes in manifest.xml and included some code in test.java file
In manifest.xml i have included <activity_name android:configChanges="orientation"/>
i entered some data in portrait mode. but when i rotate my mobile from portrait to landscape the control goes to onConfigurationChanged() method.
public void onConfigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig); setContentView(R.layout.screen1_landscape);
}
I want to call a USSD (http://en.wikipedia.org/wiki/USSD) command and have the reply returned as a String. I can make the device automatically dial the USSD - like so
// String encodedHash = Uri.encode("#"); String ussd = "*" + encodedHash + "105" + encodedHash; startActivityForResult(new Intent("android.intent.action.CALL", Uri.parse("tel:" + ussd)), 1); //
This calls the USSD and the result is displayed in an alert menu generated by the OS dialer. There's no way that I can see to intercept the USSD reply, prevent the dialer displaying it, and then use the result as a String. Essentially, all I really want to do is (pseudo code) // String ussdReply = call("*#105#"); // I've tried creating an "onActivityResult" but it never receives anything from the startActivityForResult. So, does anyone know how I can use the reply within an application?
I have an AppWidget which provides a summary of some data stored and controlled by my main Application. (In a similar way to a Calendar AppWidget showing the next event from the main Calendar application). I want to know the best practice for retrieving the data to update my widget. I have followed the example, and I have extended AppWidgetProvider and have a working widget, onto which I can update. I would expect to read the data from my main application and then update it via my AppWidgetProvider's onUpdate() routine.
Now, is the best practice here for my separate main application to provide the data via a ContentProvider? I assume so, as my Appwidget is not part of the same application. Is it possible to access a ContentProvider inside my onUpdate() routine? Before writing my main application content provider I started to test out retrieving some available data like Contacts information, and showing say a contact name in my widget, to show I can extract data from an existing ContentProvider. When accessing the Contacts contentprovider, the examples talk about:
1) Activity.managedQuery(), but my AppWidget is not an activity. 2) ContentResolver.query(), but I can't work out how to get a valid ContentResolver so I can access the Contacts. getContentResolver() does not appear to be defined for AppWidgetProviders. Am I approaching this the correct way?
I'm kinda new to android programming so please bear with me. I'm having some problems with retrieving records from the db. Basically, all I want to do is to store latitudes and longitudes which GPS positioning functions outputs and display them in a list using ListActivity on different tab later on. This is how the code for my DBAdapter helper class looks like:
public class DBAdapter
{
public static final String KEY_ROWID = "_id";
public static final String KEY_LATITUDE = "latitude";
public static final String KEY_LONGITUDE = "longitude";
private static final String TAG = "DBAdapter";....................

I am trying to set up a ViewFlipper that changes a SlidingDrawers content each time a button is pressed. So far every view I set up worked fine, but now I am trying to create a ListView (including single_choice_mode) within a child view of the ViewFlipper, but my attempt only let to a NullPointerException. As I only discovered ViewFlipper today, I am not yet familiar with it and may not have understood it completely. if someone could give me a hand and help me find out what I have done wrong, that would be great. Here is what I have done:
The code for the onClick event of the ImageButtons:
public void onClick(View v){
if (v == btnExposure){
mFlipper.setDisplayedChild(0); }
else if (v == btnProperties){
mFlipper.setDisplayedChild(1);}
else if (v == btnSpecialEffects){
mFlipper.setDisplayedChild(2);.............
I am trying to use OData4J to retrieve a list of Users from the StackOverflow OData service (onto an Android 2.1 device), but it isn't working.
public static Enumerable<OEntity> getUserInfo() {
ODataConsumer c = ODataConsumer.create("https://odata.sqlazurelabs.com/OData.svc/v0.1/rp1uiewita/StackOverflow/");
return c.getEntities("Users").execute();
I think it is unable to retrieve data from the URL. Any ideas why this would be? Is there anything wrong with my code?
I am making an application that asks the user for userid, appends the userid to a static HTTP link to retrieve the user's daily schedule info file that has a .ical (calendar) extension. I need to read the data from file, format in new UI and representing some useful data on an Android device. My query is can I access a static HTTP link behind the scenes? And when I use the same link on desktop browser, it asks user to save the file — how can I do this on a mobile? Do I need to read the data and save it somewhere or I can save the .ical file and read from it?

I have the following issue; a couple of months ago i had a Desire z (happy HTC One owner now) but it fell and it broke. Or atleast the phone itself/ screen does nothing. However i can hook the phone up to my pc and its get recognized and i can browse the phone with the command prompt.
My phone broke while i was on a trip in Thailand and unfortunately the info (email adresses from new friends) that i typed into google keep that night had not been synced yet...
I would very much like to get this info off of my phone and read it or transfer it to my new phone or something (reading it on the pc has my preference as my HTC One is not rooted).

What is "deserializing Json" means, I had seen this term on the Web. I don't know the meaning od this particular term So, it would be great if anybody can explain me about What it means actually?
View 1 Replies View RelatedI think this is the right place to look for some tips and stuff for android programming ahah. So I am completely new at all this java/android programming. My friend gave me the challenge to parse some json data as a listview. I was succesfully able to display the content as a textview however not everything appeared. Only the last few line of text showed up. He told me that by putting it as a listview everything should go well. Now setting up a listview isn't the same thing as setting up a textview. So my question is with all the code that I have how can I display the content as a listview.
