I want to create a simple widget with an icon to launch my app.
I have the widget and its layout working properly, but I can't find the way to make it launcher the app when clicking it.
This is the widget class:
public class LauncherWidget extends AppWidgetProvider {
private static final String ACTION_CLICK = "ACTION_CLICK";
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager) {
Intent intent = new Intent(context, SplashActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
// Attach the intent to the widget's button.
final PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
remoteViews.setOnClickPendingIntent(R.id.widget, pendingIntent);
}
}
I have never created a widget so I have no idea what to do here.
I have checked round here for more info but all I can find are widgets that update its content when clicking, but I tried to use their code but it isn't working.
Thanks in advance.
This is what worked for me...
The onUpdate method code should be:
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
for (int i = 0; i < appWidgetIds.length; i++) {
int appWidgetId = appWidgetIds[i];
try {
Intent intent = new Intent("android.intent.action.MAIN");
intent.addCategory("android.intent.category.LAUNCHER");
intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
intent.setComponent(new ComponentName(context.getPackageName(),
"Activity.class"));
PendingIntent pendingIntent = PendingIntent.getActivity(
context, 0, intent, 0);
RemoteViews views = new RemoteViews(context.getPackageName(),
R.layout.widget_layout);
views.setOnClickPendingIntent(R.id.widget, pendingIntent);
appWidgetManager.updateAppWidget(appWidgetId, views);
} catch (ActivityNotFoundException e) {
Toast.makeText(context.getApplicationContext(),
"There was a problem loading the application: ",
Toast.LENGTH_SHORT).show();
}
}
}
Use this snippet in onUpdate() method of your widget AppWidgetProvider class:
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widgetlayout);
Intent configIntent = new Intent(context, Activity.class);
PendingIntent configPendingIntent = PendingIntent.getActivity(context, 0, configIntent, 0);
remoteViews.setOnClickPendingIntent(R.id.widget, configPendingIntent);
appWidgetManager.updateAppWidget(appWidgetIds, remoteViews);
}

I'm trying to have my widget use an onClick action to prompt a refresh. I found some demo code that works, but it opens a URI in browser. I'm having trouble replacing the URI action with something simpler, like displaying a toast. I've marked the line that I'm trying to change, but I don't know how to make Android set a different action other than Action.VIEW.
public class NewAppWidget extends AppWidgetProvider {
static void updateAppWidget(Context context, AppWidgetManager appWidgetManager, int appWidgetId) {
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.new_app_widget);
//I AM TRYING TO CHANGE THIS INTENT
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("https://google.com/"));
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
views.setOnClickPendingIntent(R.id.refresh, pendingIntent);
appWidgetManager.updateAppWidget(appWidgetId, views);
}
#Override //Nothing changed here
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
for (int appWidgetId : appWidgetIds) {
updateAppWidget(context, appWidgetManager, appWidgetId);
}
}
}
The specific lines are
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("https://google.com/"));
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
I got this to work completely unexpectedly. I followed this post but left my intent declarations where they were. The resulting lines were:
Intent intent = new Intent(context, NewAppWidget.class);
intent.setAction(refresh);
intent.putExtra("appWidgetId", appWidgetId);
views.setOnClickPendingIntent(R.id.refresh, PendingIntent.getBroadcast(context,0,intent, PendingIntent.FLAG_UPDATE_CURRENT));
appWidgetManager.updateAppWidget(appWidgetId, views);
followed by onReceive:
#Override
public void onReceive(Context context, Intent intent) {
if(refresh.equals(intent.getAction())) {
Toast.makeText(context, "Clicked", Toast.LENGTH_LONG).show();
}
}
Edit for clarity: intent.getAction() needs to be a registered action within the receiver's intent filter.
I have no idea why this is happening. I'm making widgets which show the best currency rate for the currencies that the user chooses. I've noticed after a reboot, they sometimes turn into a clock and a calendar widget. Here's my code. I assume it could be something with my Intents or OnReceive() but I'm not sure what.
public class LightRowWidget extends RowWidget {
List<CurrencyObject> currencyObjects = new ArrayList<>();
public LightRowWidget() {
super(R.layout.widget_row_layout, R.color.white, Constants.FULL_OPACITY, R.color.black);
}
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
super.onUpdate(context, appWidgetManager, appWidgetIds);
if (appWidgetIds != null && appWidgetIds.length > 0) {
for (int appWidgetId : appWidgetIds) {
// Create currencyObjects. They're used to assign the correct value
// to the correct texView
CurrencyObject currObj1 = new CurrencyObject(
R.id.currency1, R.id.currency1_buy, R.id.currency1_sell);
currencyObjects.add(currObj1);
CurrencyObject currObj2 = new CurrencyObject(R.id.currency2, R.id.currency2_buy, R.id.currency2_sell);
currencyObjects.add(currObj2);
// Register an onClickListener to Update the current widget on a click
Intent clickIntent = new Intent(context, LightRowWidget.class);
clickIntent.setAction(AppWidgetManager.ACTION_APPWIDGET_UPDATE);
clickIntent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, appWidgetIds);
onUpdate(context, appWidgetManager, appWidgetId, currencyObjects, clickIntent);
}
//start an intent that will schedule the alarm for the next update
Intent startIntent = new Intent(context, LightRowWidget.class);
scheduleNextUpdate(context, startIntent, appWidgetIds);
}
and Here is my RowWidget class with the relevant code.
public abstract class RowWidget extends AppWidgetProvider implements WidgetInterface{
public RowWidget(int layout, int background_color, int background_opacity, int text_color){
super();
this.layout = layout;
this.background_color=background_color;
this.background_opacity=background_opacity;
this.text_color=text_color;
}
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int appWidgetId, List<CurrencyObject> currencyObjects, Intent clickIntent) {
theAppWidgetManager = appWidgetManager;
//Get the current name of class
String currentClass = this.getClass().getName();
switch(currentClass){
case("foobar"):
configure_class=Constants.FOUR_ROW_CONFIGURE;
break;
case("foo"):
configure_class=Constants.ROW_APP_WIDGET_LIGHT_CONFIGURE;
break;
case("bar"):
configure_class=Constants.ROW_APP_WIDGET_DARK_CONFIGURE;
break;
case("barfoo"):
configure_class=Constants.TWO_ROW_CONFIGURE;
break;
}
// There may be multiple widgets active, so update all of them
// Get the preferred Currencies
Set<String> preferredCurrencies = AppWidgetConfigure.loadCurrencyPref(context,appWidgetId, configure_class);
// Inflate the layout
RemoteViews view = new RemoteViews(context.getPackageName(), layout);
// if the preferred Currencies have been declared already
if(preferredCurrencies!= null){
// Set the currencies for each object
for(String currency: preferredCurrencies){
if(currencyCount<currencyObjects.size()){
currencyObjects.get(currencyCount).setCurrencyType(currency);
currencyCount+=1;
}
}
}
else{
for(CurrencyObject curObj:currencyObjects){
curObj.setCurrencyType("RUB");
}
}
// Open up the Currency fragment on the click of the widget
Intent configIntent = new Intent(context, MainActivity.class);
configIntent.putExtra("LaunchCurrency", true);
configIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent configPendingIntent = PendingIntent.getActivity(context, 0, configIntent, 0);
view.setOnClickPendingIntent(R.id.row_widget_layout, configPendingIntent);
// Update the widget whenever refresh button clicked
PendingIntent pendingIntent = PendingIntent.getBroadcast(context,
0, clickIntent, PendingIntent.FLAG_UPDATE_CURRENT);
view.setOnClickPendingIntent(R.id.refresh, pendingIntent);
makeRequest(context, theDate, view, currencyObjects, appWidgetId);
currencyCount = 0;
}
//Handle receiving the intent
#Override
public void onReceive(Context context, Intent intent){
if (intent.getAction().equals(ACTION_APPWIDGET_UPDATE)) {
AppWidgetManager manager = AppWidgetManager.getInstance(context);
// Get id's
int[] allWidgetIds = intent
.getIntArrayExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS);
onUpdate(context, manager, allWidgetIds);
}
else{
super.onReceive(context, intent);
}
}
EDIT: Widgets transform to a lot of different widgets that are already on my screen.
I have appWidgetProvider that updates views of each widget located on homescreen and each widget has a button which triggers updating the view but apparently no matter which button I press on whichever widget only and always the one of them is being updated
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
super.onUpdate(context, appWidgetManager, appWidgetIds);
for (int widgetId: appWidgetIds){
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.appwidget);
Intent update = new Intent(context, QuotesAppWidgetProvider.class);
Bundle bundle = new Bundle();
bundle.putIntArray(AppWidgetManager.EXTRA_APPWIDGET_IDS, new int[]{widgetId});
update.putExtras(bundle);
update.setAction(AppWidgetManager.ACTION_APPWIDGET_UPDATE);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, update, 0);
views.setOnClickPendingIntent(R.id.widget_refresh, pendingIntent);
appWidgetManager.updateAppWidget(widgetId, views);
}
}
Let's say I have widget with id=30 and widget with id=31 and I click the refresh button on widget30 and then widget30 is being updated which is desired but when I click on refresh button on widget31 then widget30 is being updated for I don't know what reason.
It took me a bit but I finally figured it out. All of the widgets had pendingintents with the same request code and since it was broadcast it overwritten all of them with one. This was the line that helped me:
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, widgetId, update, PendingIntent.FLAG_UPDATE_CURRENT);
Use this code and check.
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
super.onUpdate(context, appWidgetManager, appWidgetIds);
for (int widgetId: appWidgetIds){
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.appwidget);
Intent update = new Intent(context, getClass());
update.setAction("actUpdateWidgets");
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, update, 0);
views.setOnClickPendingIntent(R.id.widget_refresh, pendingIntent);
appWidgetManager.updateAppWidget(widgetId, views);
}
}
#Override
public void onReceive(Context context, Intent intent)
{
super.onReceive(context, intent);
if (intent.getAction().equalsIgnoreCase("actUpdateWidgets"))
{
Intent i = new Intent(context, QuotesAppWidgetProvider.class);
i.setAction(AppWidgetManager.ACTION_APPWIDGET_UPDATE);
int ids[] = AppWidgetManager.getInstance(context).getAppWidgetIds(new ComponentName(context, QuotesAppWidgetProvider.class));
i.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, ids);
context.sendBroadcast(i);
}
}
So far i have coded:
public class WidgetActivity extends AppWidgetProvider
{
public void onReceive(Context context, Intent intent)
{
String action = intent.getAction();
if (AppWidgetManager.ACTION_APPWIDGET_UPDATE.equals(action))
{
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget_activity);
Intent settingsIntent = new Intent(context, Info.class);
PendingIntent clickPendIntent = PendingIntent.getActivity
(context, 0, settingsIntent, PendingIntent.FLAG_UPDATE_CURRENT);
views.setOnClickPendingIntent(R.id.Widget, clickPendIntent);
AppWidgetManager.getInstance(context).updateAppWidget(intent.getIntArrayExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS), views);
}
}
}
To no success i click the widget when its on screen and nothing launches. Am I missing anything?
Put the code that makes sure the PendingIntent is set, in the onUpdate() method instead. This makes sure that as soon as the widget is put on the homescreen that the PendingIntent is set.
So:
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgets) {
RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget_activity);
Intent intent = new Intent(context, Info.class);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
remoteViews.setOnClickPendingIntent(R.id.Widget, pendingIntent);
Also:
If you would also like to have the info Activity pop up automatically when first adding the widget to the home screen, you should read this userful piece of information.
Why doesn't recieve get called when I click on Button wid??
Code:
public class Widget 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 = new Intent(context, Widget.class);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget);
views.setOnClickPendingIntent(R.id.wid, pendingIntent);
appWidgetManager.updateAppWidget(appWidgetId, views);
}
}
#Override
public void onReceive(Context context, Intent intent) {
super.onReceive(context, intent);
Log.d("ARH","CLICKK");
}
Becuase I need a button to manual refresh the widget but it seems that Log.d("ARH","CLICKK"); only gets called when i add the Widget.
Thanks!
You using a PendingIntent to call an Activity but your Widget class is not an activity.
If you want to update to your widget, then you need to use getBroadcast that sends an APPWIDGET_UPDATE action.
