widget is working on background after kill the app.so can you guide me to set current time on my widget.

CodePudding user response：

You can use timer as chronometer. it work like countdown timer and you don't need background service for that.

You Can Implement like this :

Widget XML

           <Chronometer
            android:id="@ id/chronometer"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginVertical="6dp"
            android:textColor="@color/white"
            android:textSize="20sp"
            android:textStyle="bold" />

AppWidgetProvider

val view = RemoteViews(context?.packageName, R.layout.timer_widget)
val startTime: Long = SystemClock.elapsedRealtime()
view.setChronometer(R.id.chronometer,startTime 120000,"%tH:%tM:%tS",true)
view.setChronometerCountDown(R.id.chronometer,true)//if you want to reverse countdown
appWidgetManager?.updateAppWidget(appWidgetId, view)
