Android :: Passing Variable String To Create Arrays (Android)
May 24, 2010
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 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 am working to set a countdown timer. I have successfully (borrowed) a number picker (spinner) and set up the dialog box for the user to set the time. This is in a class called timepickactivity and the variables are hour and mins (R.id.hour and R.id.mins). I want to call the set values (R.id.hour and R.id.mins) from the dialog (timepickeractivity) to the actual countdown class (countdown) but I can't figure out how to get the values.

I have a list view with several columns; things such as name, date, etc. I want to be able to click on the header TextView and sort the list by that field. When the list loads the variable works, and a list is queried and sorted by the field _id (no surprise other than it works), but when i click on the header TextView I get a force close:
Thread [<3> main] (Suspended (exception SQLiteException))
ViewRoot.handleMessage(Message) line: 1757
ViewRoot(Handler).dispatchMessage(Message) line: 99
Looper.loop() line: 123
ActivityThread.main(String[]) line: 4595
Method.invokeNative(Object, Object[], Class, Class[], Class, int, boolean) line: not available [native method]
Method.invoke(Object, Object...) line: 521
ZygoteInit$MethodAndArgsCaller.run() line: 860
ZygoteInit.main(String[]) line: 618
NativeStart.main(String[]) line: not available [native method]
The TextView gives no errors when not changing my orderby variable.
Setting Variable:
private View.OnClickListener NameSortbtnListener = new View.OnClickListener(){
public void onClick(View v){
sort = " KEY_JOURNAL_TITLE ";
fillData();
} };
Populating List:
private void fillData() {
Cursor notesCursor = mDbHelper.fetchAllJournals(sort);
startManagingCursor(notesCursor);
String[] from = new String[]{journalDbAdapter.KEY_JOURNAL_TITLE,
journalDbAdapter.KEY_LOCATION, journalDbAdapter.KEY_JDATE,
journalDbAdapter.KEY_STEPS};
int[] to = new int[]{R.id.text1, R.id.text2, R.id.text3, R.id.text4};
SimpleCursorAdapter notes =
new SimpleCursorAdapter(this, R.layout.notes_row, notesCursor,
from, to);
setListAdapter(notes);
}
Query (In DB Adapter):
public Cursor fetchAllJournals(String sort) {
return mDb.query(DATABASE_JOURNAL_TABLE, new String[] {KEY_JROWID,
KEY_JOURNAL_TITLE, KEY_JOURNAL_NOTES, KEY_JDATE, KEY_LOCATION,
KEY_STEPS},null , null, null, null, sort ,null);
}

I recently created a program that gets medi-large amounts of xml data and converts it into arrays of Strings, then displays the data.The program works great, but it freezes when it is making the arrays (for around 16 seconds depending on the size).Is there any way I can optimize my program (Alternatives to string arrays etc.)

Does anybody know of a work around for the android xml file string array inability to process string <item>'s that are not legal java variable names If not, is this not a major bug? Why does an item in an array need to generate a reference id anyway? Isn't this redundant?

I would like to setup a boolean called dFlag in the main.class of my program and reference it in another class.
I already have it setup to work locally just hitting a snag on how to do it.
Code:
public class Main extends Activity {
boolean dFlag; ///Debug flag, true=enabled | false=disabled
}
public class Other extends Activity {
if(dFLag = true) {
///Output debug message
}
}
Or is there an easier way to do what I want without having to re-invent the wheel so to speak?

I'm not very clear about the Intent object and how to use it to pass data between Activities. In my application I have several tabs between which I want to pass ArrayList. Here is a sample code I plan to use, but I'm missing the part where the main activity catches the Intent and passes it to the new activity on start :
1. myTabs.java ==> This is where I think I need to add some code to pass the data between TabOne and TabTwo. For now it is just using the sample code of the TabActivity sample.
CODE:...........
2. TabOne.java ==> I added a piece of code in the onStop procedure to fill in the Intent data with the array I want to pass to TabTwo. Not sure it is the right way to do though.
CODE:...................

I am having a unicode string "u3403" which is actualy some japansee character I want to pass it through a JSON object. So i put the value as say String str ="u3403" jsonObject.put("name",str); When i do this the json object internally adds another escape sequence as "u3403", and the request string has two "" slashes.This is interpreted wrongly by the server as it does not detect unicode name.What can i do for this?

i'm making a program that needs to set to a textview the content of a string stored in resource/string file
in my program i generate a string and i need to set the text using that string like a resource id. the problem is that the resouurce ids are integers.
something like:
test = (TextView) findViewById(R.id.tvMyTV);
mystring = "test_a";
test.setText(Html.fromHtml(getString(R.string.myst ring)));
-----------
i obviously can't use R.string.mystring, i should use
test.setText(Html.fromHtml(getString(R.string.test _a)));

I am looking for a way to create dynamic preferences where I don't need to hard code the preference key and I could have a variable number of preferences. Basically, my application will let the user create a multiple number of profiles and each of these profiles will save custom values for a fixed number of preferences. So this way, the user does not have to change the preferences every time he wants this app to run differently, he can just switch the profile. One way I think will work is by subclassing all the standard Preference classes and calling their setKey method with my custom preference key, containing the profile name, but this is ugly. So is there a cleaner and more standards compliant way to do this?

Is copying the reference to the object and not the value of the object. Meaning, when I modify pos.top or pos.bottom, the original object gets modified. I'm guessing I am missing a concept of pass object by reference vs value here which I thought I understood. What is the fix here? Is it a problem with how I defined my custom class?

I have a problem with my DDMS in eclipse. In the logcat view appears only this failure: Logcat View fails with "Could not create the view: For input string: "our" "
I uninstalled and reinstalled the adt and ddms already without any change. I can use the logcat in the command line (tools- adt logcat) but this is not as comfortable as using the logcat in eclipse.

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 am trying to create a information based application, I have 92 subjects, for these subjects I have 92 map locations and maybe as much as 400 url links. Currently I have created a class for each map location and a class for each url link, but this would mean I would have in excess of 500 classes, so what I want to do is split the subjects in four catergories ie. listview of about 23 in four tabs which I have done and create a class that gets the url based on the selection the use makes and do the same for the map locations.Do I need to put these in a xml using the id method and how do you call individual entries, i.e. would I need 500 Android:id is there an easier way?
