Android :: Button Click Does Not Start Service In App Widget
May 31, 2010
I'm having trouble starting a Service to update an AppWidget that I'm creating as an exercise. I'm trying to get the latitude and longitude of spoofed location data from DDMS to display in the widget. The widget uses a service to update the TextView, which may be slightly overkill, but I wanted to follow the template that seems to be common in AppWidgets that do more work (like the Forecast widget or the Wiktionary widget).
Right now, I'm not getting any error messages or strange behavior; nothing at all happens when the button is pressed. I'm a bit mystified as to what might be wrong. Could anyone out there point me in the right direction?
Additionally, if my logic for location is faulty, I'd love recommendations on that too. I've looked at several blogs, the Google examples, and the documentation, but I feel a little fuzzy on how it works.
Here is the current state of the widget:

I saw this topic and implement IntentService as describes, but what if I want more that one button? How can I distinguish button from each other?
I'm trying to setFlags, but cannot read it at onHandleIntent() method code...
At this little piece of code I have two PendingIntent linked with setOnClickPendingIntent, can I distinguish this intent for different actions and processing?

I have a very simple widget application which consists of a linear layout with a background and an image button. In the AppWidgetProvider on Update method, I register the click of the button to broadcast an intent. When the widget first loads, everything runs fine and the click is captured. The problem occurs when the screen is rotated, and the click is never captured again even if the screen is rotated back. What do I have to do to re-register the click when the screen rotates? below is some segments of code I am using.
AppWidgetProvider
@Override
public void on Receive(Context context, Intent intent)
{super.on Receive(context, intent);
if(intent.getAction().equals("test.CLICK"))
{Closemouthed(context);}}
@Override
public void on Update(Context context, AppWidgetManager appWidgetManager,int[] appWidgetIds)final int N = appWidgetIds.length;
// Perform this loop procedure for each App Widget that belongs to this provider for (int i=0; i<N; i++) {
int appWidgetId = appWidgetIds[i]; RemoteViews views=new RemoteViews(context.getPackageName(), R.layout.widget);
Intent click intent=new Intent("test.CLICK");
Pending Intent pendingIntentClick=Pending Intent.getBroadcast(context, 0, click intent, Pending Intent.FLAG_UPDATE_CURRENT);
views.setOnClickPendingIntent(R.id.change_mode, pendingIntentClick);
SetInitialLayout(context);
appWidgetManager.updateAppWidget(appWidgetId, views);}
super.on Update(context, appWidgetManager, appWidgetIds);}
Manifest
<receiver android:name=".Widget" android:label="@string/widget_name">
<intent-filter>
<action android:name="android.appwidget.action.ACTION_APPWIDGET_CONFIGURE" />
<action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
<action android:name="test.CLICK" />
</intent-filter>
<meta-data android:name="android.appwidget.provider" android:resource="@xml/widget_mode_switcher" />
</receiver

I have made a Android Widget which displays two articles (title + image). In addition to this, I have buttons for flipping backward and forward through the articles. What I don't understand is how I can change the Widgets RemoteViews when the buttons are pressed. Which should be one of the most basic operations in a widget, however, I can't seem to figure it out.
So... Can I do this with just a OnClickListener in the AppWidgetProvider? Or do I have to create an Activity without a window (visibility = false)?

I have just started my career as an android programmer, and am currently relying heavily on the sample code and api examples. I have been working with this api example, to produce an expandable list of items (note this example does not use the ExpadableListView).In playing with the example, I tried to add another widget that would become visible and be gone at the same time as the text (mDialogue in the sample code). This works well with another TextView, but as soon as I tried to add a button widget, it stopped working. The list would expand on first click, showing my hidden TextView and Button, but it will not disappear on further clicks. The button is however, clickable, and I was able to set up an onClick listener to change the button text back and forth.I'm starting to wonder, is it just not possible to have a clickable item inside a clickable list item? Or is there some kind of work around? Would it solve my problem if I used ExpandableListView?

I like being able to wake the phone to view the lock screen using the home button at the bottom of the phone, but is there any way to make it so that a second click of that button, or a click of one of the others down there, will make it sleep again? Having to press the power button up top is just an inconvenience.

CODE:............
I have this at the top of my application. When the application starts, the EditText is orange highlighted and has a cursor in it; when the EditText is tapped, the soft keyboard pops up. The user uses it to type into the EditText.
However, when they click the Button, my onClick method fires and does everything it's supposed to, however the soft keyboard stays on screen and the EditText is still highlighted with its cursor.
I also have, at the top of the Button onclick: findViewById(R.id.name).clearFocus();
In spite of this, the EditText does not seem to clear its focus. How do I make the button actually act as if it is submitting the form?
Also, I do not transition to a different Activity on the click of the Button. I suppose that is the typical case, and probably the reason why they don't bother hiding the keyboard. However I want to keep the search box and button at the top of the screen, so I just dynamically fill and add views to the screen when the Button is pressed. How can I achieve my desired behavior?

I want, that when the user clicks on a button, a textfield with a number will increase or decrease. But this should be work in a way, that the user leaves the finger on the button and the number increases automatically. Therefore he doesn´t have to click lot of times.I have not found any method to override that could implement such behaviour! Does anybody know how to implement this?

I am trying to follow a tutorial to learn how to get to a new screen on a button click. The issue I feel I am facing is that in this tutorial they have a file named main.java, firstly I don't have such a file. I think I named the file as name1.java and on this screen i have everything going on including this button I am trying to make. So I m really confused as in this article below they have the main.java file and from that file they are moving to screen 1 and screen 2. Is it so important to have a main.java from where we branch the two activities?

I created a ListView that contains a row which in turn contain text and a button. The idea is to have the button function as a delete button to remove the row from the list as well as the database. I order to do this I created an adapter to handle the button click. This code is below. Deleting the database record works fine, but I have not yet succeeded in refreshing the ListView so the record will no longer be displayed.
public class FeedArrayAdapter extends ArrayAdapter {
private ARssEReaderDBAdapter dba;
private String TAG = "FeedArrayAdapter";
private View v;
private ListView feedList;..............

Each row of my view look like that:.............
When I click on the ImageButton "arrow", I trigger a method than need the id of the row to perform. By ID I mean the value of the field "_id" of the corresponding record in database. I did not find a direct way to do it, but I think I can if I get the index of the row in the ListView. Again, I don't know how to get this index from a click to a childview.

I'm trying automate UI Functional testing of my application.
1) First phase: Record the user actions and playing back the same.
2) Second Phase: Adding Validation Capability to Recorded scripts.
In First Phase: I'm able to automate the Text/Editbox control actions without any issues, because we need to Set the Text of the control to the recorded value, so, its simple. While coming to Button Control actions, we need to simulate user actons, like Clicking on button. Can anyone suggest me, Do we have any mechanism, which can simulate button click event in Android?

I have an activity which starts with a progress bar and I do not want the progress bar to go away until the processing is done, I have set the dialog to be setCancelable(false) so now user cannot cancel it with back but there are several other situations which hides the dialog for eg pressing 'search'.On clicking of 'search' button the search box and keyboard pops up,back button hides it and shows my activity which is always in the background but the dialog is gone.I can disable the search button but ideally I would want dialog to come back when the activity comes in foreground again. Any ideas how to do it?

Wondering if I'm going about this the right way or not. I have 3 buttons on my screen (Restart, Previous, Next). When the view loads it shows the first image which is fine. When I click the "Next" button I want it to load a second image and so on for up to 9 images. If I click the "Previous" button it should go back one image. Clicking "Restart" should go to the first image. I have the Restart one working. I'm having trouble with the Next button because it only shows the second image (I think because my "a" variable is initialized at 0).
