I want to pass a variable to an outer function when user clicks on "OK" in AlertDialog. I'm trying this for example but it won't recognize the Variable.
CODE:....................
I know the code is a bit messed up but it's only for the sake of understanding.

Is there a way to have 1 onClick Lister for many buttons where I can toss a case statement to do things based on what buttons were clicked.
I know I can make 100 different listeners for 100 buttons but I have to think I can create some nifty variables to do it in less lines of code.
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.
View 4 Replies View RelatedI 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

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'm very new on Android development.
I have this code...
But this line doesn't work:
extraData.putInt(Constants.GAME_ID, this.gameId);
I can't get access to this.gameId.
How can I fix this?
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 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 am trying to figure out what is the best way to go about creating dialogs. I can either create my own Dialog class (which, to me, is more clean and organized), or I can use AlertDialog.Builder (which would be done inline, and funky looking)... What are the positivies and negatives of either implementation?
View 1 Replies View RelatedIs 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?

So far I'm starting from the ground up and making sure I can intercept a call at the users discretion. I have an Receiver registered in the Manifest of my program with a filter of Phone_State which flags when the state has changed(IE incoming call).
So on my BroadcastReceiver I'm trying to have an AlertDialog popup prompting the user to either accept as fax or call but the AlertDialog seems to throw a android.view.WindowManager$BadTokenException Error when it has an incoming call.

From what I have seen in the AlertDialog code, it passes the context as well as a Window and WindowManager, which I believe is why it's crashing, is there a better way or something else I should be using which might overlay the call screen?
I have a TabActivity with 3 tabs. Each tab contains its own Activity. When one of the contained Activities pops up an AlertDialog, there are actually 3 dialogs created. The dialog has a Dismiss button and it must be pressed 3 times to finally dismiss the 3rd dialog.
View 2 Replies View Relatedjust a short question for a better understanding: I'm developing an app based on the Android 1.5 Framework (with compatibility down to 1.1). But now I read about the new way of implementing click-handlers in Android 1.6 on the Android Developer Blog and I'd really like to use that in my app because it makes developer's life so much easier :) But can I use this (and the 1.6 Framework) without losing backward compatibility to 1.5 and 1.1? Best regards and sorry if this question is dumb [I just didn't find anything via google]

I have a DialogPreference in my Preference Activity and would like to know which button was pressed. I have implemented the OnSharedPreferenceChangeListener which does not seem to get triggered when the DialogPreference is selected. I have also tried OnPreferenceClickListener but this gets triggered as soon as the DialogPreference is clicked from the main screen and not when one of the actual dialog buttons was pressed. I think I need to implement onClick for this dialog but I am not sure where to do this. I have looked at the API Demo code and it shows how to create the dialog but not how to determine which button was pressed.
public class Preferences extends PreferenceActivity implements OnSharedPreferenceChangeListener {
private static final String LOG = "test"; private DialogPreference mfactory;
