Android :: Copy String From EditText Into String Variable
Jul 27, 2010
I have a class that creates a view to gather data via a function getView() that provides a view with an EditText.This class has also has variable answer.When the user chances the EditText I want to store the content of the EditText in answer.If I would use an onKeyListener I fear that the answer will probably get stored before the last letter is entered.Is there a good way to handle this in the getView() function via some other listener?

I have an EditText for which will be using for a float number. So I'm trying to read the text from the EditText and put it into a float variable. But I seem to have a text to float problem.I've tried using Float.parseFloat(string) and just general casting, but nothing seem to do it. What can I do here? Also, is there a way to check for a valid float number before writing it to a variable?

I have the localized strings file that is used in the Iphone app that I work on to port to Android. Are there any tools that go through the file taken from the xcode project and build the xml needed to use the strings in android? This tool should be easy to build but I appreciate any pointers to already working tools.

In Android, capturing date from datepicker and storing as string in sqlite. Sorting by date doesn't work because they're strings (unless I'm doing it wrong.I've googled this issue for ~5 days, and it looks like there should be a way to capture the date from the date picker, convert it to a Long, store it in sqlite as a Long, select and sort on the Long date value, then convert the Long back to a "mm/dd/yyyy" string for display. I've tried various combinations of parse statements, Date, FormatDate, etc. with no luck at all.On activity start, get today's date and display it in button which calls the datepicker.Capture new date from datepicker (if one is entered), save it as a long to sqlite.On opening an activity showing a listview of records, select from sqlite with orderby on date (Long), convert Long to "mm/dd/yyyy" string for display in ListView.

I have preferences where you can enable/disable what items will show up on the menu. There are 17 items. I made a string array in values/arrays.xml with titles for each of these 17 items.
I have preferences.xml which has the layout for my preferences file, and I would like to reference a single item from the string array to use as the title.
In the Android developer reference, I see how I can reference a single string with XML, but now how I can reference a string from an array resource in XML.

I'm trying to use the code below to connect to an online source, then compare the data as it is read line by line against what is typed in an EditText field before displaying the next page. At the moment when I run it and press the "Sign In" button nothing happens. The problem seems to be with the comparison of the data.

I have an Android app where I want to check to see if an app name that is installed matches a string passed to the function containing this code.Assuming you called checkInstalledApp('SetCPU'); and the app name on the phone is called the same thing it should return true. However, it never does. I logged the results and it should match up but it does not. Can anyone please enlighten me as to why this doesn't work?

Does anyone have any idea how to find the n-th field (string) in a delimited string where the delimiters (separator) could be either a single char or several chars.and the syntax for user-defined function is FindNthField(string,separator,position)so position 3 would return three,The separator in use would actually be Chr(13).This has to run on Android and so should be efficient.

I am a newb to Android and Java and want to write a funtion that will display a list based on a varable that I pass to the function. The function is below and the code below creates an array out of a string called type, but what I want to do is pass it a variable string and have it build a list based on that string. So if I wanted the type list I would say list_it("type")But if I try something like getResources().getStringArray (R.array.thelist); it doesn't work.Can someone point me in the right direction? public void list_it(String thelist){String[] types = getResources().getStringArray(R.array.type); ArrayAdapter<String> mAdapter = new ArrayAdapter<String>(this, R.layout.list_item1, types);
setListAdapter(mAdapter);
ListView lv = getListView();
lv.setTextFilterEnabled(true);

I have installed Power Strip, and the very first time I was asked to use my preferred home screen, I selected the existing one (using a GS).
What I want to do is to have Power String dock displayed if I do a double click on the home key. I played with the settings but it seems that it doesn't work. Any hint?

I just want to read <string-array> resource elements into a String array. I don't want to make a view or anything and mess with adapters - just want to transfer the elements. Is there a built in class for this? Or do I need to treat the resource file as a regular file?

I am coding an Android client that talks to some web services via XML packets.
A typical packet looks like this..
<Packet service="login">
<username></username>
<password></password>
</Packet>
I have about 20 of these packets and would like to store them in my resources maybe in res/xml or res/raw
I want to store these 'empty' packets and load them using XML DOM and then fill in the content between the tags or attributes but am unsure how to do this.
Once the DOM packet has been filled in I want to get that back as a String so that I can send the packet to the server.
So to summarize my questions are..
(1) How do I load an XML resource using DOM?
(2) How do I convert the DOM object to a String?
