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'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:
CODE:.....................
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" />

I am trying to populate a TextView based on the current selected options in 3 Spinner(s) but cant seem to figure out how to retrieve the selected values from the Spinners to invoke the update function with.
Here is my current code (quite messy but I'm just learning Java,
public class AgeFun extends Activity {
private String[] dayNames;
private String[] yearArray;
private final static int START_YEAR = 1990;
private static TextView textDisp;
private Button calcButton;
private static Spinner spinnerDay, spinnerYear, spinnerMonth;
private static ArrayAdapter<?> monthAdapter, dayAdapter, yearAdapter;
private int year, month, day;
/** Called when the activity is first created. */
@Overridepublic void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
year = 2000;
month = 1;
day = 1;
textDisp = (TextView) findViewById(R.id.textView1);
calcButton = (Button) findViewById(R.id.button);
calcButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// Perform action on clicks
AgeFun.updateAge(year, month, day);
// Month spinner
spinnerMonth = (Spinner) findViewById(R.id.spinnerFirst);
monthAdapter = ArrayAdapter.createFromResource(
this, R.array.monthList, android.R.layout.simple_spinner_item);
monthAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinnerMonth.setAdapter(monthAdapter);
// Day spinner
dayNames = new String[31];
for(int i =1; i <= 31; ++i)
{ dayNames[i-1] = Integer.toString(i);
} spinnerDay = (Spinner) findViewById(R.id.spinnerSecond);
dayAdapter = new ArrayAdapter<CharSequence>(this, android.R.layout.simple_spinner_item, dayNames);
spinnerDay.setAdapter(dayAdapter);
// Year spinner
yearArray = new String[40];
for(int i =0; i < 40; ++i)
{ yearArray[i] = Integer.toString(START_YEAR+i);
} spinnerYear = (Spinner) findViewById(R.id.spinnerThird);
yearAdapter = new ArrayAdapter<CharSequence>(this, android.R.layout.simple_spinner_item, yearArray);
spinnerYear.setAdapter(yearAdapter);
updateAge(2000,1,1);
}private static void updateAge(int year, int month, int day) {
Date dob = new GregorianCalendar(year, month, day).getTime();
Date currDate = new Date();
long age = (currDate.getTime() - dob.getTime()) / (1000 * 60 * 60 * 24) / 365;
textDisp.setText("Your are " + Long.toString(age) + " years old");
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.
View 5 Replies View RelatedI 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?

View 2 Replies View RelatedCODE:............
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?
View 2 Replies View RelatedI 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?

View 2 Replies View RelatedI 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.

View 2 Replies View RelatedWondering 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).
View 1 Replies View RelatedI have been reading a lot of comments on how it is more lightweight to use views instead of intents in setContent when using tabs.
Since I will be creating an app with tabs, I am trying to implement this instead of having intents inside setContent. However, I am having a difficult time looking for examples or straightforward tutorials on swapping the current view with another one.
Say I have TAB_A, with some entry fields and a button. When the user clicks on the button, a TextView will display "Hello, user!" in the same TAB_A. Of course this is an oversimplified example, but it will surely point me in the right direction.
EDIT: I have a tab called TAB_A with a button in it. If the user clicks on that button, TAB_A will now display "Hello, user!" instead of the button.
Here is a sample of my TabSpec.
CODE:..............
Where ShowButton and ShowHello are classes both extending LinearLayout. Both are initialized in onCreate like this:
CODE:.............
When the app first starts, the user sees the view showButton. When the user clicks on the button, I want the tab to change its contents to showHello.
The question then is: Is there any way to update the contents of the tabspec without using startActivity?
I have an application, when it launches I have to disable all the buttons, I successeded in disabling end call and other i need to disable home buttom if I click it, It should not produce any action.
