I am trying to create a simple widget. I wanted that, when touchet, to show a toast. But it does not show anything. I don't know where I'm wrong, it looks quite well(maybe i have forgotten something i didn't notice).
Code:
static String clAc = "CLICKED";
static void updateAppWidget(Context context, AppWidgetManager appWidgetManager,
int appWidgetId) {
Intent intent = new Intent(context, LocationWidget.class);
intent.setAction(clAc);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context,0, intent,0);
Paper.init(context);
String title = Paper.book().read("content");
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.location_widget);
views.setTextViewText(R.id.appwidget_text, title);
views.setOnClickPendingIntent(R.id.layout_wrapper, pendingIntent);
appWidgetManager.updateAppWidget(appWidgetId, views);
}
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
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
}
#Override
public void onReceive(Context context, Intent intent) {
super.onReceive(context, intent);
if(intent.getAction().contentEquals(clAc))
Toast.makeText(context, "clicked",Toast.LENGTH_LONG).show();
}
Try to update not each appWidgetId, but all appWidgetIds with your logic.

My app widget class code:
MyWidget.java:
public class MyWidget extends AppWidgetProvider {
static Context cont;
static SharedPreferences preferences;
static void updateAppWidget(Context context, AppWidgetManager appWidgetManager,
int appWidgetId) {
cont = context;
Intent intent2 = new Intent();
intent2.setAction("....");
PendingIntent pendingIntent = PendingIntent.
getBroadcast(context, 0,
intent2, PendingIntent.FLAG_UPDATE_CURRENT);
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.my_widget);
views.setOnClickPendingIntent(R.id.appwidget_text, pendingIntent);
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);
}
}
#Override
public void onReceive(Context context, Intent intent) {
super.onReceive(context, intent);
context.startService(new Intent(context, MyService.class));
}
#Override
public void onEnabled(Context context) {
.................. }
#Override
public void onDisabled(Context context) {
.................}
Always use an explicit Intent whenever possible. Your code would not work on Android 8.0 and higher, where implicit broadcasts are banned. And an explicit Intent can move your app out of the stopped state.
I need to create Widgets in my android app similar work flow of contact widgets in android. But the problem facing is if there are n widgets of the same application each widgets have different functionality. how to differentiate the button click on each widgets.?
public class MyWidgetActivity extends AppWidgetProvider {
private static final String MyOnClick = "myOnClickTag";
static void updateAppWidget(Context context, AppWidgetManager appWidgetManager,
int appWidgetId) {
CharSequence widgetText = MyWidgetActivityConfigureActivity.loadTitlePref(context, appWidgetId);
// Construct the RemoteViews object
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.simple_widget);
views.setTextViewText(R.id.appwidget_text, widgetText);
views.setOnClickPendingIntent(R.id.actionButton, getPendingSelfIntent(context, MyOnClick,views.getLayoutId()));
// 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);
// Tell the AppWidgetManager to perform an update on the current app
// widget
}
}
#Override
public void onDeleted(Context context, int[] appWidgetIds) {
// When the user deletes the widget, delete the preference associated with it.
for (int appWidgetId : appWidgetIds) {
MyWidgetActivityConfigureActivity.deleteTitlePref(context, 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
}
#Override
public void onReceive(Context context, Intent intent) {
super.onReceive(context, intent);
if (MyOnClick.equals(intent.getAction()))
{
int appWidgetId = intent.getIntExtra(EXTRA_APPWIDGET_ID,0);
Log.e("KOKOKOKO :: ",""+appWidgetId);
MyWidgetActivityConfigureActivity.loadIdPrefCallQuick(context,appWidgetId);
//your onClick action is here
Toast.makeText(context,"Quick Action Triggered",Toast.LENGTH_SHORT).show();
}
super.onReceive(context, intent);
}
static PendingIntent getPendingSelfIntent(Context context, String action, int appWidgtId)
{
// if we brodcast than definetly we have to define ONRECEIVE
Intent intent = new Intent(context, MyWidgetActivity.class);
intent.putExtra(EXTRA_APPWIDGET_ID,appWidgtId);
intent.setAction(action);
return PendingIntent.getBroadcast(context, 0, intent, 0);
}
}
Instead of this code (static PendingIntent getPendingSelfIntent) :
return PendingIntent.getBroadcast(context, 0, intent, 0);
You should do this :
return PendingIntent.getBroadcast(context, appWidgtId, intent, PendingIntent.FLAG_UPDATE_CURRENT);
This way you should get unique intent and also unique appWidgtId.
It is important to set requestCode (2nd attribute of getBroadcast), so it wouldn't conflict.
I'm a newbie and i'm finding difficulty in getting texts from a string array. I tried creating a widget in my app and i wanted the widget to update it's text view from the string array i declared in the resources folder, but this does not seams to work out. Here is my code.
MainActivity.Java
public class MainActivity extends AppCompatActivity {
public static TextView Quote;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Quote = (TextView) findViewById(R.id.appwidget_text);
final String[] Quotes = getResources().getStringArray(R.array.Qoutes);
Random rand = new Random();
int randNum = rand.nextInt(Quotes.length);
Quote.setText(Quotes[randNum]);
}}
NewAppWidget.java
public class NewAppWidget extends AppWidgetProvider {
static void updateAppWidget(Context context, AppWidgetManager appWidgetManager,
int appWidgetId) {
CharSequence widgetText = MainActivity.Quote.getText().toString();
// Construct the RemoteViews object
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.new_app_widget);
views.setTextViewText(R.id.appwidget_text, 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);
}
Intent intent = new Intent(context, MainActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(context,0 , intent, 0);
RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.new_app_widget);
remoteViews.setOnClickPendingIntent(R.id.interfaceID,pendingIntent);
appWidgetManager.updateAppWidget(appWidgetIds, remoteViews);
}
#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
}}
Thank You
I am building a static android widget, which means the widget doesn't need to be updated at all. The only thing that widget need to handle is open link from browser when it is triggered.
In the AppWidgetProviderInfo Metadata xml file, there is one attribute called "updatePeriodMillis", and should I set any value there? or just don't add this attribute?
Thanks
Why not just override onUpdate() in your AppWidgetProvider class and have it do nothing.
public class MyWidget extends AppWidgetProvider {
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
//do nothing
}
}
in your widgetprovider file write this method:
#Override
public void onReceive(Context context, Intent intent) {
ComponentName thisAppWidget = new ComponentName(context.getPackageName(), getClass().getName());
AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(context);
int ids[] = appWidgetManager.getAppWidgetIds(thisAppWidget);
int idd[];
idd = appWidgetManager.getAppWidgetIds(thisAppWidget);
// call updateAppWidget for each widget
for (int appWidgetID : ids) {
updateAppWidget(context, appWidgetManager, appWidgetID);
}
super.onReceive(context, intent);
}
public void updateAppWidget(Context context,AppWidgetManager appWidgetManager, int appWidgetId){
RemoteViews updateViews = new RemoteViews(context.getPackageName(),R.layout.widget_layout1_1);
updateViews.setTextViewText(R.id.txt_days, "" + tmp_diffrentDays);
appWidgetManager.updateAppWidget(appWidgetId, updateViews);
}
try above code it will work for me
I want to add a button in my widget so that it can run a function(change APN and display a changed message in the widget) by press a button. In fact, the function is worked since I have tested in an activity. Did anyone have idea how to do it? thanks!

Well, there is couple of ways.
For example you can make something like this inside registered AppWidgetProvider:
public static String ACTION_WIDGET_RECEIVER = "Action!";
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
int[] appWidgetIds) {
RemoteViews remoteViews = new RemoteViews(context.getPackageName(),
R.layout.widget_layout);
Intent active = new Intent(context, ThisClass.class);
active.setAction(ACTION_WIDGET_RECEIVER);
PendingIntent actionPendingIntent = PendingIntent.getBroadcast(context,
0, active, 0);
remoteViews.setOnClickPendingIntent(R.id.button, actionPendingIntent);
appWidgetManager.updateAppWidget(appWidgetIds, remoteViews);
}
#Override
public void onReceive(Context context, Intent intent) {
final String action = intent.getAction();
if (AppWidgetManager.ACTION_APPWIDGET_DELETED.equals(action)) {
final int appWidgetId = intent.getExtras().getInt(
AppWidgetManager.EXTRA_APPWIDGET_ID,
AppWidgetManager.INVALID_APPWIDGET_ID);
if (appWidgetId != AppWidgetManager.INVALID_APPWIDGET_ID) {
this.onDeleted(context, new int[] { appWidgetId });
}
} else {
if (intent.getAction().equals(ACTION_WIDGET_RECEIVER)) {
doYourStuff();
super.onReceive(context, intent);
}
}
