I have made FlashLight widget. In home screen it's working perfect. When i add it as Lock Screen Widget it's shown but not turning on flashlight by clicking (or not clickable). Can anyone let me know , what mistake ma i doing? I am using HTC ONE m7 with KITKAT updated. Thanks in advance for your help.
Here is the code:
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
int[] appWidgetIds) {
final int N = appWidgetIds.length;
for (int i=0; i<N; i++) {
int appWidgetId = appWidgetIds[i];
createWid(context,appWidgetManager,appWidgetId);
}
}
private void createWid(Context context, AppWidgetManager appWidgetManager, int appWidgetId) {
// TODO Auto-generated method stub
Intent i0 = new Intent();
i0.setAction("com.cookbook.SMSresponder.AEScreenOnOffService");
context. startService(i0);
Intent receiver = new Intent(context, FlashlightWidgetReceiver.class);
receiver.setAction("COM_FLASHLIGHT");
receiver.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, appWidgetId);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, receiver, 0);
RemoteViews views = new RemoteViews(context.getPackageName(),
R.layout.activity_smsr_responder);
views.setOnClickPendingIntent(R.id.buttonWidgetStopService, pendingIntent);
appWidgetManager.updateAppWidget(appWidgetId, views);
}

I have a widget that display a simple text and 3 buttons:
Refresh (Picks another random string and displays it)
Copy (Copy the contents of the textview to the clipboard)
Share (Share the content of the textview to social media and such)
I already Got the refresh button setup and working just fine but I can't seem to figure out a way to handle the other two buttons
PS. I don't need the actual code I already know how to do the copying and sharing I just need to know how to handle click events
Here is my code so far:
Button copy_content;
Button share_content;
void updateAppWidget(Context context, AppWidgetManager appWidgetManager, int appWidgetId) {
/** Code below will be executed once the timer is over*/
String widgetText = RandQuotes[rand.nextInt(RandQuotes.length)];
// Construct the RemoteViews object
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.quotes_widget);
views.setTextViewText(R.id.sayings, widgetText);
// Instruct the widget manager to update the widget
appWidgetManager.updateAppWidget(appWidgetId, views);
}
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
// There may be multiple widgets active, so update all of them
for (int appWidgetId : appWidgetIds) {
updateAppWidget(context, appWidgetManager, appWidgetId);
}
final int count = appWidgetIds.length;
for (int i = 0; i < count; i++) {
int widgetId = appWidgetIds[i];
String on_sayings = RandQuotes[rand.nextInt(RandQuotes.length)];
RemoteViews remoteViews = new RemoteViews(context.getPackageName(),
R.layout.quotes_widget);
remoteViews.setTextViewText(R.id.sayings, on_sayings);
Intent intent = new Intent(context, HavamalWidget.class);
intent.setAction(AppWidgetManager.ACTION_APPWIDGET_UPDATE);
intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, appWidgetIds);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context,
0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
remoteViews.setOnClickPendingIntent(R.id.switch_trigger, pendingIntent);
appWidgetManager.updateAppWidget(widgetId, remoteViews);
}
}
Just make pending intents on buttons with action. So in onReceive() just check action of intent and make some logic on that. If you make some long tasks, better to make all logic in IntentService.
Set pending intents on your buttons that are in RemoteViews like this:
public static final String ACTION_BUTTON_SHARE = "ACTION_BUTTON_SHARE";
public static final String ACTION_BUTTON_REFRESH = "ACTION_BUTTON_REFRESH";
Intent refreshIntent = new Intent(context, ExampleAppWidget.class)
.setAction(ACTION_BUTTON_REFRESH);
PendingIntent refreshPI = PendingIntent.getBroadcast(context, 0, refreshIntent,
PendingIntent.FLAG_UPDATE_CURRENT);
remoteViews.setOnClickPendingIntent(R.id.refresh_button, refreshPI);
Intent shareIntent = new Intent(context, ExampleAppWidget.class)
.setAction(ACTION_BUTTON_SHARE);
PendingIntent sharePI = PendingIntent.getBroadcast(context, 0, shareIntent,
PendingIntent.FLAG_UPDATE_CURRENT);
remoteViews.setOnClickPendingIntent(R.id.share_button, sharePI);
In ExampleAppWidget.class (that extends from AppWidgetProvider) override OnReceive() method
#Override
public void onReceive(Context context, Intent intent) {
if (intent != null) {
if (intent.getAction().equals(ACTION_BUTTON_REFRESH)) {
//make some logic here on button refresh
} else if (intent.getAction().equals(ACTION_BUTTON_SHARE)) {
//make some logic here on button share
} else {
super.onReceive(context, intent);
}
}
}
I made an widget which have the image and show the time. howerver , the time cannot update.so I try to implement that the time will be updated when user click on the widget.
I find some tutorial said that using setOnClickPendingIntent can do this but my code not work.
Any solutions can let the widget update the time onClick or Auto Updating?
public class NewAppWidget extends AppWidgetProvider {
static void updateAppWidget(Context context, AppWidgetManager appWidgetManager,
int appWidgetId) {
CharSequence widgetText = DateFormat.getTimeInstance(DateFormat.SHORT).format(new Date());;
// Construct the RemoteViews object
RemoteViews updateViews = new RemoteViews(context.getPackageName(), R.layout.new_app_widget);
Intent intent = new Intent(context, NewAppWidget.class);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
updateViews.setOnClickPendingIntent(R.id.imageView, pendingIntent);
updateViews.setTextViewText(R.id.editText2, widgetText);
// Instruct the widget manager to update the widget
appWidgetManager.updateAppWidget(appWidgetId, updateViews);
}
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
// There may be multiple widgets active, so update all of them
for (int appWidgetId : appWidgetIds) {
updateAppWidget(context, appWidgetManager, appWidgetId);
}
}
#Override
public void onEnabled(Context context) {
// Enter relevant functionality for when the first widget is created
}
#Override
public void onDisabled(Context context) {
// Enter relevant functionality for when the last widget is disabled
}
}
Change you PendingIntent like this
Intent intent = new Intent()
intent.putExtra(EXTRA_VALUES, values)
intent.setComponent(new ComponentName(context, NewAppWidget.class));
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, intent,
PendingIntent.FLAG_UPDATE_CURRENT);
I have an app widget and the click event can be received in onUpdate() in my provider.
However, when I try to force close the home launcher, the click event is lost.
I even put breakpoints in all onEnabled(), onReceived()...etc: the connection seems to be lost.
As a result, how can I "re-connect" the button event?
WidgetProvider extends AppWidgetProvider:
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
Log.d(TAG, "onUpdate()");
Log.d(TAG, "isLoading: " + CONSTANT.isLoading);
// update each of the widgets with the remote adapter from updateService
// Get all ids
ComponentName thisWidget = new ComponentName(context, ScoreWidgetProvider.class);
int[] allWidgetIds = appWidgetManager.getAppWidgetIds(thisWidget);
// Build the intent to call the service
Intent intent = new Intent(context.getApplicationContext(), UpdateWidgetService.class);
intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, allWidgetIds);
// Update the widgets via the service
context.startService(intent);
// super.onUpdate(context, appWidgetManager, appWidgetIds);
}
UpdateWidgetService extends Service:
#Override
public void onStart(Intent intent, int startId) {
Log.i(TAG, "Called");
AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(getApplicationContext());
int[] appWidgetIds = intent.getIntArrayExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS);
for (int i = 0; i < appWidgetIds.length; ++i) {
// Here we setup the intent which points to the StackViewService which will
// provide the views for this collection.
Intent remoteViewsIntent = new Intent(this.getApplicationContext(), ScoreWidgetRemoteViewsService.class);
remoteViewsIntent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetIds[i]);
// When intents are compared, the extras are ignored, so we need to embed the extras
// into the data so that the extras will not be ignored.
remoteViewsIntent.setData(Uri.parse(remoteViewsIntent.toUri(Intent.URI_INTENT_SCHEME)));
RemoteViews rv = new RemoteViews(this.getApplicationContext().getPackageName(), R.layout.widget_layout);
rv.setRemoteAdapter(appWidgetIds[i], R.id.score_list, remoteViewsIntent);
// Set the empty view to be displayed if the collection is empty. It must be a sibling
// view of the collection view.
rv.setEmptyView(R.id.score_list, R.id.empty_view);
// Bind the click intent for the refresh button on the widget
final Intent refreshIntent = new Intent(this.getApplicationContext(), ScoreWidgetProvider.class);
refreshIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
refreshIntent.setAction(ScoreWidgetProvider.REFRESH_ACTION);
final PendingIntent refreshPendingIntent = PendingIntent
.getBroadcast(this.getApplicationContext(), 0, refreshIntent, PendingIntent.FLAG_UPDATE_CURRENT);
rv.setOnClickPendingIntent(R.id.btn_refresh, refreshPendingIntent);
appWidgetManager.updateAppWidget(appWidgetIds[i], rv);
}
// stopSelf();
super.onStart(intent, startId);
}
Make sure that you are using the correct context in your onStart function. Check out getApplicationContext in the onStart part of your code, passing in the wrong type of context can cause errors. Here is a link for more information: Context.
I am currently trying to implement a configuration activity which allows for manipulating the widget.
I have looked at the official document, as well as many other blogs,
but do not understand how to change the content of the widget through the configuration activity.
I want to set the String targetName to a TextView in R.layout.widget_layout.
It says I need to update the widget through the configuration activity,
but what happens to the onUpdate code in WidgetProvider.java if I update it in the configuration activity? This is the part that is confusing me the most.
Here is part of my code:
Configure.java extending ActionBarActivity
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_configure);
setResult(RESULT_CANCELED);
context = this;
final Bundle extras = getIntent().getExtras();
if (extras != null) {
appWidgetId = extras.getInt(AppWidgetManager.EXTRA_APPWIDGET_ID, AppWidgetManager.INVALID_APPWIDGET_ID);
}
final AppWidgetManager widgetManager = AppWidgetManager.getInstance(context);
final RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget_layout);
final TextView textView = (TextView) findViewById(R.id.batteryText);
final int targetId;
db = new DatabaseHandler(this);
loadListView(); // not present here
registerForContextMenu(listView);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
targetName = serverArrayList.get(position).getName();
widgetManager.updateAppWidget(appWidgetId, views);
Intent resultValue = new Intent();
resultValue.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId);
setResult(RESULT_OK, resultValue);
finish();
}
});
}
WidgetProvider.java extending AppWidgetProvider
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
super.onUpdate(context, appWidgetManager, appWidgetIds);
for (int i = 0; i < appWidgetIds.length; i++) {
int appWidgetId = appWidgetIds[i];
Intent intent = new Intent();
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget_layout);
appWidgetManager.updateAppWidget(appWidgetId, views);
}
}
Thanks in advance.
Doing a bit more research,
I found this question.
Despite the title being a bit misleading,
I think I've solved it, so I'll be closing this question.
Android - Custom Widget doesnt update
Below is some code for my widget extending AppWidgetProvider. The widget renders correctly when put on a home screen, but the view is empty. Using logging, I found that no methods are called from the classes I used to extend RemoteViewsService (BudgetWidgetService), which returns an implementation of RemoteViewsService.RemoteViewsFactory.
Is there a mistake causing BudgetWidgetService to never be instantiated or used?
I can't even find a way to check if the BudgetWidgetService is even bound to the RemoteViews layout I create. If you can think of any I can further diagnose this problem, other than logging method calls in my AppWidgetProvider and extension of RemoteViewsService, I would appreciate that as well,
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
Log.i("Budget Widget", "Provider onUpdate called");
// Update each of the widgets with the remote adapter
for (int i = 0; i < appWidgetIds.length; ++i) {
RemoteViews layout = buildLayout(context, appWidgetIds[i]);
appWidgetManager.updateAppWidget(appWidgetIds[i], null);
appWidgetManager.updateAppWidget(appWidgetIds[i], layout);
}
super.onUpdate(context, appWidgetManager, appWidgetIds);
}
private RemoteViews buildLayout(Context context, int appWidgetId) {
Log.i("Budget Widget", "Provider buildLayout called");
RemoteViews rv = new RemoteViews(context.getPackageName(), R.layout.widget_budget);
RemoteViews list_item = new RemoteViews(context.getPackageName(), R.layout.widget_budget_item);
list_item.setTextViewText(R.id.widget_budget_item_text, "Test #1");
final Intent intent = new Intent(context, BudgetWidgetService.class);
intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId);
intent.setData(Uri.parse(intent.toUri(Intent.URI_INTENT_SCHEME)));
rv.setRemoteAdapter(R.id.widget_budget_list, intent);
rv.setEmptyView(R.id.widget_budget_list, R.id.empty_view);
final Intent refreshIntent = new Intent(context, BudgetWidgetProvider.class);
refreshIntent.setAction(BudgetWidgetProvider.REFRESH_ACTION);
final PendingIntent refreshPendingIntent = PendingIntent.getBroadcast(context, 0,
refreshIntent, PendingIntent.FLAG_UPDATE_CURRENT);
rv.setOnClickPendingIntent(R.id.refresh_button, refreshPendingIntent);
return rv;
}
I was having the same problem, and discovered that I had forgotten to add the android.permission.BIND_REMOTEVIEWS permission to my RemoteViewsService in my AndroidManifest.xml:
<service android:name="MyWidgetService"
...
android:permission="android.permission.BIND_REMOTEVIEWS" />
I found my answer under the section "Manifest for app widgets with collections" on the App Widgets guide.
