I need to show different data when the different widget will be clicked. For example widget one will show me activity with number 1 and widget to with numer 2 :)
Perhaps I can send some data by intent from widget, but then how to recive that data in activity class?
Widget class
Intent intent = new Intent(context, Information.class);
intent.putExtra("widget_id", appWidgetId);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget1x1);
remoteViews.setOnClickPendingIntent(R.id.widget_layout, pendingIntent);
Bundle extras = intent.getBundle();
String id = extras.getString("widget_id");

I'm doing a widget with one stackView which i'm adding bitmaps(images) inside with a RemoteViewFactory.
My problem is when I want to do a onClickPendingIntent() for each image (that I have inside the stackView). I know I have to use setPendingIntentTemplate() instead, but I don't know how to go to an Activity when I press some widget's image.
Then this is what I have inside onUpdate() from widget class to create the Pending Intent Template:
Intent templateIntent = new Intent(Intent.ACTION_VIEW);
templateIntent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId);
PendingIntent templatePendingIntent = PendingIntent.getActivity(
context, 0, templateIntent, PendingIntent.FLAG_UPDATE_CURRENT);
views.setPendingIntentTemplate(R.id.widget_stack_view,
templatePendingIntent);
And this is what I have in a RemoteViewsFactory class to handle the Pending Intent Template:
public RemoteViews getViewAt(int index){
RemoteViews rv = new RemoteViews(context.getPackageName(), R.layout.grid_item_layout);
rv.setImageViewBitmap(R.id.image, images.get(index).getImage());
Intent fillInIntent = new Intent();
fillInIntent.putExtra(Intent.EXTRA_TEXT, images.get(index).getTitle());
rv.setOnClickFillInIntent(R.id.image, fillInIntent);
return rv;
}
So far, this fillInIntent.putExtra(Intent.EXTRA_TEXT, images.get(index).getTitle()); is acting with the phone showing me a "use complete actions" where you can choose with which app you want to open, but if you see what i'm putting in the putExtra() is a String. But what I want is open a Activity and then pass with putExtra() a image (images.get(index).getImage()) that is a bitmap
I figured out what was wrong:
Intent templateIntent = new Intent(context, Activity_I_want_to_open.class);
templateIntent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId);
PendingIntent templatePendingIntent = PendingIntent.getActivity(
context, 0, templateIntent, 0);
Then, I didn't need to FLAG_UPDATE_CURRENT, because I want to updating nothing.
And in the RemoteViews side:
Intent fillInIntent = new Intent();
rv.setOnClickFillInIntent(R.id.image, fillInIntent);
I didn't need putExtra() because I'm not sending data to other activity.
How can i go to my App when i click on AppWidget
I saw no. of questions how to create widget in android home,but after craeting widget how to go to my app while clicking on that i didn't get from anyone of that.Please give me the guidelines to achieve this.
Thanks,
Since it is an AppWidget setting an onClickListener won't work. Instead you have to set an onClickPendingIntent on a specific view.
See the following code for the necessary steps (you should put this code into your onUpdate() method):
// Inflate the Widget layout
RemoteViews remoteViews = new RemoteViews(context.getPackageName(),
R.layout.your_widget_layout);
// Create and set the Intent
Intent intent = new Intent(context, MyClass.class);
PendingIntent pendingIntent = PendingIntent.getActivity(context, appWidgetId, intent,
PendingIntent.FLAG_CANCEL_CURRENT);
// Add intent to a view (like a button)
remoteViews.setOnClickPendingIntent(R.id.your_button, pendingIntent);
Please note: The code only shows the relevant parts
As greenapps say :
Add a listener in your widged's view (e.g : click)
Create an intent and put extra information (e.g witch item is clicked)
Then start your activity.
e.g
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
//...
Intent intent = new Intent(context, YourActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget);
views.setOnClickPendingIntent(R.id.widget_layout, pendingIntent);
//...
}
}
I want to combine my widget and one of my android application..
Is it possible to do that?
My plan is, once user open up my android widget, the widget will directly open up my android application?
Is there any way how?
I made some method here from my widget class:
public class ExampleAppWidgetProvider extends AppWidgetProvider {
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
int[] appWidgetIds) {
for (int i = 0; i < appWidgetIds.length; i++) {
int appWidgetId = appWidgetIds[i];
Intent intent = startActivity(new Intent("com.xxx.yyy.widget.FlamingoActivity"));
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0,
intent, 0);
RemoteViews views = new RemoteViews(context.getPackageName(),
R.layout.widget1);
views.setOnClickPendingIntent(R.id.Image, pendingIntent);
appWidgetManager.updateAppWidget(appWidgetId, views);
}
}
I tried to call the second app, FlamingoActivity, but its failing.. :(
NOT THE FULL SOLUTION:
I should change this line
Intent intent = startActivity(new Intent("com.xxx.yyy.widget.FlamingoActivity"));
to this:
Intent intent = new Intent(context, FlamingoActivity.class);
You need to set an onClickpendingIntent on your widget
Intent intent = new Intent(context, ExampleActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
// Get the layout for the App Widget and attach an on-click listener to the button
RemoteViews views = new
RemoteViews(context.getPackageName(),R.layout.appwidget_provider_layout);
views.setOnClickPendingIntent(R.id.button, pendingIntent);
And also See this question Launching activity from widget
The activity that you are trying to call needs to be public (exported) in the manifest of its app. There is nothing special about starting activities from a widget, other than the fact that you use a PendingIntent to allow the widget to work as a part of your app (it runs inside the launcher app).
I'm working on an appWidget which has a textView, all i want is preview this textView in a new activity that i launch with
Intent configIntent = new Intent(context, ViewFromWidget.class);
configIntent.setAction(ACTION_WIDGET_CONFIGURE);
PendingIntent myPendingIntent = PendingIntent.getActivity(context, 0, configIntent, 0);
remoteViews.setOnClickPendingIntent(R.id.widgetLayout, myPendingIntent);
Can some one point me out on how can i send a string to the new activity that u start via appWidget?
That should be easy, you want to use an intent extra for passing strings.
Add this before setAction
configIntent.putExtra("MyKey", myString);
And in the activity getting the intent use getStringExtra
String passedString = getIntent().getStringExtra("MyKey");
I have a widget, its setup so that when I click on it, it opens some settings in an activity.
views.setOnClickPendingIntent(R.id.btnActivate, pendingIntent);
This configures some settings for the application. What I want to achieve is to have the widget update its view to reflect the changed settings when the Activity I launch closes. Using the update interval or any other type of polling isn't appropriate for this.
I've seen a couple places here and in the android docs this code used:
appWidgetManager.updateAppWidget(mAppWidgetId, views);
But I don't know how to get the mAppWidgetId value. I tried following the example for a widget configuration activity here http://developer.android.com/guide/topics/appwidgets/index.html, but in the following code,
Intent intent = getIntent();
Bundle extras = intent.getExtras();
if (extras != null) {
mAppWidgetId = extras.getInt(
AppWidgetManager.EXTRA_APPWIDGET_ID,
AppWidgetManager.INVALID_APPWIDGET_ID);
}
extras is always null, so I never get the AppWidgetID.
Ok, now I'm just rambling. What do you think I can do?
I finally found the answer I was looking for, it was in an overload of the updateAppWidget function.
appWidgetManager.updateAppWidget(new ComponentName(this.getPackageName(), Widget.class.getName()), views);
This let me access the widget without having to know the appWidgetID. My final code in my activity is then:
// Create an Intent to launch ExampleActivity
Intent intent = new Intent(this, Settings.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, 0);
views.setOnClickPendingIntent(R.id.btnActivate, pendingIntent);
AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(this);
appWidgetManager.updateAppWidget(new ComponentName(this.getPackageName(), Widget.class.getName()), views);
finish();
I have to do all the same setup stuff I had to do in the onUpdate method of the Widget, but now every time I exit my activity the Widget is displaying the correct state.
There's another way to do it - pass the widget id in the pending intent that you use to start the activity:
Intent clickIntent=new Intent(context, MyConfigActivity.class);
clickIntent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, widgetId);
// you have the widgetId here, since it's your onUpdate
PendingIntent pendingIntent=PendingIntent
.getActivity(context, 0,
clickIntent,
PendingIntent.FLAG_UPDATE_CURRENT);
views.setOnClickPendingIntent(R.id.btnActivate, pendingIntent);
Moreover, to avoid duplication of code from onUpdate(), you can broadcast an intent back to the AppWidgetProvider:
Intent intent = new Intent(this,MyAppWidgetProvider.class);
intent.setAction("android.appwidget.action.APPWIDGET_UPDATE");
// Use an array and EXTRA_APPWIDGET_IDS instead of AppWidgetManager.EXTRA_APPWIDGET_ID,
// since it seems the onUpdate() is only fired on that:
int[] ids = {widgetId};
intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS,ids);
sendBroadcast(intent);
I know this has been answered and accepted way ago. However while I was searching the same thing I came across an awesomely simple way to update the widget.
For future readers:
The best part, this works for all the instances of the widget and from any context (Activity, Service etc)
Heres the code,
Context context = this;
AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(context);
RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget_2x1);
ComponentName thisWidget = new ComponentName(context, MyWidget.class);
remoteViews.setTextViewText(R.id.my_text_view, "myText" + System.currentTimeMillis());
appWidgetManager.updateAppWidget(thisWidget, remoteViews);
Courtesy - Stuck :)
Instead of doing the call from your activity, I prefere to send a broad cast request to the widget for updating. The onUpdate method will be triggered and all widget layouts are passed.
Here is my code below:
1- sending broad cast from the activity:
Intent intent = new Intent(ctxt, MyAppWidgetProvider.class);
intent.setAction(AppWidgetManager.ACTION_APPWIDGET_UPDATE);
int[] ids = {R.layout.appwidget};
intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS,ids);
ctxt.sendBroadcast(intent);
and now, 2- implement the onUpdate method:
Intent i = new Intent(ctxt, Settings.class);
PendingIntent pi = PendingIntent.getActivity(ctxt, 0, i, 0);
for (int widgetId : allWidgetIds) {
RemoteViews remoteViews = new RemoteViews(ctxt.getPackageName(), widgetId);
remoteViews.setTextViewText(R.id.statusMsg, msg);
remoteViews.setOnClickPendingIntent(R.id.rootView, pi);
AppWidgetManager mngr = AppWidgetManager.getInstance(ctxt);
ComponentName wdgt = new ComponentName(ctxt, MyAppWidgetProvider.class);
mngr.updateAppWidget(wdgt, remoteViews);
}
That is it! I wish it helps you :)
RemoteViews view = new RemoteViews("pakagename", R.layout.widget_layout_name);
view.setTextViewText(R.id.textView_id, String.valueOf(hr + ":" + mi)); // for setting a textview
view.setCharSequence(R.id.PunchIn, "setText", "Punch In"); //for setting a button name
view.setInt(R.id.PunchIn, "setBackgroundResource", R.color.black); //for setting button color
ComponentName theWidget = new ComponentName(getActivity(), AppWidget_name.class);
AppWidgetManager manager = AppWidgetManager.getInstance(getActivity());
manager.updateAppWidget(theWidget, view);
