La barra di avanzamento circolare del timer per il conto alla rovescia Android non corrisponde al timer

Question

Ciao qualcuno mi può aiutare nel mio piccolo progetto per favore, ho seguito questo tutorial e sono arrivato alla parte in cui inserisco 1 minuto in EditText la barra di avanzamento funziona bene 1 Progresso al secondo ma quando inserisco più di 1 minuto in EditText la barra di avanzamento non funziona. Non va giù per favore aiutatemi?

normale stato di Timer

Quando entro 1 minuto

quando sono entrato 3 minuti

Barra di avanzamento non è il conto alla rovescia

Answer 1

Nella tua main.xml , per ProgressBar hai menzionato il valore massimo come 60. Quindi il la barra di avanzamento assume il valore massimo di 60 e la barra di avanzamento inizia a decrescere da 60 secondi in poi.

Invece di eseguire correttamente la barra di avanzamento tutte le volte, nel metodo "setTimer()" scrivi la riga seguente.

mProgressBar.setMax(60*time);
