i want to display a dialog in my android application where certain TextViews in the layout need to have content set during runtime. while showing the dialog itself is no problem at all, accessing the TextViews via TextView.setText(String) crashes the application.

Anybody else notice that the SD cards are write protected? If I take out my card and put it in a card reader on my laptop, I can add stuff to the card, but I can't delete anything. If I put it back in the phone and mount the sd card, I can edit the card how I want. weird?

I want to display a keypad with numbers and mathematical operations and when the user presses the keys the corresponding number is displayed in edit text. I tried using get text() and updating the contents of edit text but it shows just the contents of pressed button. Also how do I read the contents of button so as to do mathematical operations in code?

View 1 Replies View RelatedI'm creating an Android app, where the user starts out seeing a list of questions. When the user clicks a question, I would like to show him a new clickable list, containing that question and its answer alternatives.
My questions reside in rows in the database. The questions live in the first column, while the answer alternatives live in the following columns.
I've managed to display any single element from the row when I click a question in the list, but how to display more than one completely eludes me.
This is the relevant source code in the intent entered when the user clicks a question:
private void fillData() {
Bundle extras = getIntent().getExtras();
Long id = extras != null ? extras.getLong(QuestionsDbAdapter.KEY_ROWID) : null;
Cursor questionsCursor = mDbHelper.fetchQuestion(id);
startManagingCursor(questionsCursor);
String[] from = new String[]{mDbHelper.KEY_QUESTION,
mDbHelper.KEY_ALT1,mDbHelper.KEY_ALT2};
int[] to = new int[]{R.id.text1};
SimpleCursorAdapter questions =
new SimpleCursorAdapter(this, R.layout.questions_one_row,
questionsCursor, from,to);
setListAdapter(questions);}
This displays only the question. If I put one of the answer alternatives first in the 'String[] from ...' statement, that gets displayed instead.
I'm doing an APP that shows some dialogs. Those dialogs are Alert dialogs, and when they are being showed if I change the orientation of the mobile I lost them...they are not being kept on the screen.
View 13 Replies View RelatedI have 6 options to put in options Menu, but 3 of them are not so important and i want to hide them in submenu. All of my Activities are started from one ActivityGroup which creates Menu on MENU button press. Problem is that when I open SubMenu or Dialog (which is created and displayed by ActivityGroup) my current foreground activity makes onPause, onStop and onDestroy, and when I close this submenu (using "back" key) or dialog (by "ok" button for ex.) I don't have any response (onCreate, onResume) from any of my activities registered in LocalActivityManager.

View 2 Replies View RelatedI've read the answer to a question as to how to access the contents of the databases, however I cannot seem to get it to work on my machine. Here is the shell log:
C:android-sdk-windows ools>adb -s emulator-5554 shell
# sqlite3 /data/data/com.android.demo.notepad2/databases/notes
sqlite3 /data/data/com.android.demo.notepad2/databases/notes
SQLite version 3.5.9
Enter ".help" for instructions
sqlite> .tables
.tables
sqlite> ^C
C:android-sdk-windows ools>
SQLite simply echos my commands back to me, even although the Eclipse file browser tells me it exists. If I use the sqlite3 tool and use ".tables" the commands are accepted.
Is the SQLite syntax different through the emulator is am I missing something?
Is there a simple way to change the contents of a dialog box in Android without having to re-create the dialog box? I know that Activity.onCreateDialog() is only called once when the dialog first needs to be created, and this is where you initially set the dialog's contents. I need to change the dialog's contents later, so I'm wondering what is the proper way to do this.

View 17 Replies View RelatedI have tried to make a series of dialogs, like a questionnaire, that the user needs to answers a series of questions selecting one or more checkboxes. I can do one, just fine, but when I try to make more than one question (lets say 10), it does not show, or show all the dialogs. I tried using dialogs or new acitivities.
So, my problem is I have multiple questions, one to be presented each time, and I need to wait for one to be responded so I can ask the next one. How do I accomplish this?
My first attempt was with a dialog box... but obviously it got all the boxes stacked in each other:
CODE:.................
I intended to show a dialog in a service process, then I tried to use the AlertDialog but got the below error message: WindowManager$BadTokenException: Unable to add window -- token null is not for an application The reason seems to be that the dialog is not used in a application context (activity should be fine?) Was there any way that can solve this problem?
View 2 Replies View RelatedI'm facing the same head-scratching moment similar to what this person (from Jan 2008) experienced when I realize that there is no cancel button in Android's progress dialog or spinners. It is now July 2009 and I've just installed the cupcake version of Android. Has this thing changed ? If not, are you adding a cancel button into the dialogs and how do you do it ?
View 4 Replies View RelatedI wonder what is the right way to implement this? Could anybody advice whether my solution is correct?
So:
Activity is created
User clicks on button and dialog is launched (Dialog, not dialog styled activity)
User opens keyboard
we have onSaveInstanceState called where we save that our dialog was opened and all respective dialog input
we have onRestoreInstanceState and here we check whether dialog was shown, recreate the dialog with respective input.
Is it the right approach? or there is smth. that is done by Android and I am doing some redundant actions.
I use the AlertDialog class in my application. By default, these alert dialogs have a transparent background. I'm trying to use an opaque background instead, very unsuccessfully.
These are my styles:
CODE:....................
I applied the "MyOpaqueActivity" style successfully for whole activities (the window background is changed to "my_background"), but it doesn't work for alert dialogs within those activities. The "alertDialogStyle" attribute and my "MyOpaqueAlertDialog" style don't seem to have any effect.
So how can I change the background of these alert dialogs?
I am trying to create a map application and I need to do something similar to what Google Maps does. I want to open show a list of locations and when user taps on them I want to show a dialog.
I was able to do it till here. But now when the user clicks on the dialog that opened I want to show another acttivity with the details of that item that they clicked on.
I tried to start a new intent but it gives me an error.
Here is what I am doing

Why am I getting this error and how can I resolve this and open a new activity? Also where can I find the source code for the google maps on android?

View 2 Replies View RelatedI've read on Reto Meier's blog that he doesn't recommend the use of modal "Loading" dialogs in Android applications. Is this a general consensus among developers? If I have a login screen what should I display when the user tries to sign in? Until now, I have used a "Signing in" indeterminate progress dialog. Should I use the application's progress bar? Should I use a Toast? And, in the general case, when should I use dialogs and when not to?
View 1 Replies View RelatedI am rendering an EditText as one element of a list-style AlertDialog (which is backed by the default ListView implementation). I sort of expected that this circumstance would not change the behavior of EditText, but it does: a click on the EditText does not spawn the soft keyboard anymore.
After an hour of messing around with focus settings and click handlers I got fed up and debugged into InputMethodManager.showSoftInput(), and found this:
CODE:....................
The problem here is that mServedView is the ListView that's backing the dialog, while view is the EditText, and ListView.checkInputConnectionProxy() does simply return false in the default implementation of ListView (to be overridden by subclasses).
Worse, I couldn't find a way to set a custom ListView which allows proxying IME reuqests; AlertDialog.Builder.setView() accepts a custom ListView, but this is not the ListView that InputMethodManager sees.
I've had this problem in a few different apps now and I can't seem to find a solution.
If, in the onCreate() of an Activity, I start an activity that uses the dialog theme it doesn't draw anything to screen... the whole screen stays black. All the views are there (e.g., I can tap where an EditText should be and it'll give me the keyboard), they're just not visible. code...
Does anyone know how to make a dialog fill the screen width in landscape mode? Setting the layout's width to fill_parent doesn't do it. It always comes up portrait width, or something suspiciously similar.
