I have the following widget service which updates a text view when I click on my one button.
UpdateWidgetService:
ipublic class UpdateWidgetService extends Service {
private static final String LOG = "widgetService";
private static final String MyOnClick1 = "myOnClickTag1";
private static final String MyOnClick2 = "myOnClickTag2";
private static final String MyOnClick3 = "myOnClickTag3";
static LocationClient mLocationClient;
@Override
public void onStart(Intent intent, int startId) {
Log.i(LOG, "Called and started");
AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(this.getApplicationContext());
int[] allWidgetIds = intent.getIntArrayExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS);
ComponentName thisWidget = new ComponentName(getApplicationContext(), MyWidgetProvider.class);
int[] allWidgetIds2 = appWidgetManager.getAppWidgetIds(thisWidget);
Log.w(LOG, "From Intent" + String.valueOf(allWidgetIds.length));
Log.w(LOG, "Direct" + String.valueOf(allWidgetIds2.length));
for (int widgetId : allWidgetIds) {
// create some random data
int number = (new Random().nextInt(100));
RemoteViews remoteViews = new RemoteViews(this.getApplicationContext().getPackageName(), R.layout.widget_layout);
Log.w("WidgetExample", String.valueOf(number));
// Set the text
remoteViews.setTextViewText(R.id.widget_textview_gpscoords, "Random: " + String.valueOf(number));
// Register an onClickListener
Intent clickIntent = new Intent(this.getApplicationContext(), MyWidgetProvider.class);
clickIntent.setAction(AppWidgetManager.ACTION_APPWIDGET_UPDATE);
clickIntent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, allWidgetIds);
PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(), 0, clickIntent, PendingIntent.FLAG_UPDATE_CURRENT);
remoteViews.setOnClickPendingIntent(R.id.widget_button_dissarm, pendingIntent);
appWidgetManager.updateAppWidget(widgetId, remoteViews);
}
stopSelf();
super.onStart(intent, startId);
}
@Override
public IBinder onBind(Intent intent) {
return null;
}
}
MyWidget Provider:
public class MyWidgetProvider extends AppWidgetProvider {
private static final String LOG = "de.vogella.android.widget.example";
@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
Log.w(LOG, "onUpdate method called");
// Get all ids
ComponentName thisWidget = new ComponentName(context, MyWidgetProvider.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);
}
}
android manifest:
<!-- Widget -->
<receiver
android:name="widget.MyWidgetProvider"
android:icon="@drawable/icon"
android:label="My Widget" >
<intent-filter>
<action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
</intent-filter>
<meta-data
android:name="android.appwidget.provider"
android:resource="@xml/example_appwidget_info" />
</receiver>
<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
<!-- Services -->
<service android:name="widget.UpdateWidgetService" >
</service>
Now my issue is that, how do I determine which button gets clicked? I have 4 buttons on my widget and I want to differentiate between which ones are clicked? In my example the intent for the buttons onclick is ACTION_APPWIDGET_UPDATE Im thinking I need to change that some how?
What is the correct way to go about doing this?
Ultimately my buttons are each going to make a webcall, this is why I am using the service, as the web call can take some time.
I would change your UpdateWidgetService.java as the code below.
public class UpdateWidgetService extends Service {
private static final String LOG = "widgetService";
// my changes - part 1 - beginning
private static final String BUTTON_ONE_CLICKED = "com.yourpackage.BUTTON_ONE_CLICKED";
private static final String BUTTON_TWO_CLICKED = "com.yourpackage.BUTTON_TWO_CLICKED";
private static final String BUTTON_THREE_CLICKED = "com.yourpackage.BUTTON_THREE_CLICKED";
private static final String BUTTON_FOUR_CLICKED = "com.yourpackage.BUTTON_FOUR_CLICKED";
// my changes - part 1 - end
@Override
public void onStart(Intent intent, int startId) {
Log.i(LOG, "Called and started");
// my changes - part 2 - beginning
if(BUTTON_ONE_CLICKED.equals(intent.getAction())) {
// do what should be done if button One has been clicked
}
if(BUTTON_TWO_CLICKED.equals(intent.getAction())) {
// do what should be done if button Two has been clicked
}
if(BUTTON_THREE_CLICKED.equals(intent.getAction())) {
// do what should be done if button Three has been clicked
}
if(BUTTON_FOUR_CLICKED.equals(intent.getAction())) {
// do what should be done if button Four has been clicked
}
// my changes - part 2 - end
AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(this.getApplicationContext());
int[] allWidgetIds = intent.getIntArrayExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS);
ComponentName thisWidget = new ComponentName(getApplicationContext(), MyWidgetProvider.class);
int[] allWidgetIds2 = appWidgetManager.getAppWidgetIds(thisWidget);
Log.w(LOG, "From Intent" + String.valueOf(allWidgetIds.length));
Log.w(LOG, "Direct" + String.valueOf(allWidgetIds2.length));
for (int widgetId : allWidgetIds) {
// create some random data
int number = (new Random().nextInt(100));
RemoteViews remoteViews = new RemoteViews(this.getApplicationContext().getPackageName(), R.layout.widget_layout);
Log.w("WidgetExample", String.valueOf(number));
// Set the text
remoteViews.setTextViewText(R.id.widget_textview_gpscoords, "Random: " + String.valueOf(number));
// my changes - part 3 - beginning
Context context = getApplicationContext();
Intent buttonOneIntent = new Intent(context, UpdateWidgetService.class);
Intent buttonTwoIntent = new Intent(context, UpdateWidgetService.class);
Intent buttonThreeIntent = new Intent(context, UpdateWidgetService.class);
Intent buttonFourIntent = new Intent(context, UpdateWidgetService.class);
// set action
buttonOneIntent.setAction(BUTTON_ONE_CLICKED);
buttonTwoIntent.setAction(BUTTON_TWO_CLICKED);
buttonThreeIntent.setAction(BUTTON_THREE_CLICKED);
buttonFourIntent.setAction(BUTTON_FOUR_CLICKED);
// put widgetId
buttonOneIntent.putExtra("widgetId", widgetId);
buttonTwoIntent.putExtra("widgetId", widgetId);
buttonThreeIntent.putExtra("widgetId", widgetId);
buttonFourIntent.putExtra("widgetId", widgetId);
// make these intents unique to avoid collisions
buttonOneIntent.setData(Uri.withAppendedPath(Uri.parse("webcall_widget://buttonone/widgetid"), String.valueOf(widgetId)));
buttonTwoIntent.setData(Uri.withAppendedPath(Uri.parse("webcall_widget://buttontwo/widgetid"), String.valueOf(widgetId)));
buttonThreeIntent.setData(Uri.withAppendedPath(Uri.parse("webcall_widget://buttonthree/widgetid"), String.valueOf(widgetId)));
buttonFourIntent.setData(Uri.withAppendedPath(Uri.parse("webcall_widget://buttonfour/widgetid"), String.valueOf(widgetId)));
// pending intents
PendingIntent buttonOnePendingIntent = PendingIntent.getService(context, 0, buttonOneIntent, PendingIntent.FLAG_UPDATE_CURRENT);
PendingIntent buttonTwoPendingIntent = PendingIntent.getService(context, 0, buttonTwoIntent, PendingIntent.FLAG_UPDATE_CURRENT);
PendingIntent buttonThreePendingIntent = PendingIntent.getService(context, 0, buttonThreeIntent, PendingIntent.FLAG_UPDATE_CURRENT);
PendingIntent buttonFourPendingIntent = PendingIntent.getService(context, 0, buttonFourIntent, PendingIntent.FLAG_UPDATE_CURRENT);
// register onClickListeners to your buttons
remoteViews.setOnClickPendingIntent(R.id.button_one, buttonOnePendingIntent);
remoteViews.setOnClickPendingIntent(R.id.button_two, buttonTwoPendingIntent);
remoteViews.setOnClickPendingIntent(R.id.button_three, buttonThreePendingIntent);
remoteViews.setOnClickPendingIntent(R.id.button_four, buttonFourPendingIntent);
// my changes - part 3 - end
appWidgetManager.updateAppWidget(widgetId, remoteViews);
}
stopSelf();
super.onStart(intent, startId);
}
@Override
public IBinder onBind(Intent intent) {
return null;
}
}
