Android - Aplikace neodpovídá – Java – Fórum – Programujte.com

Dobrý večer, 

právě jsem začal programovat v Javě pro Android, ale aplikace mi neustále vypisuje, že neodpovídá. 

Vůbec nevím jak je to možné. 

Děkuji za odpověď

        TextView casText = (TextView) findViewById(R.id.casTextView);
        
        long hodinaNyni = casNyni.HOUR;
        long minutaNyni = casNyni.MINUTE;
        long sekundaNyni = casNyni.SECOND;
        
        casText.setText(Long.toString(hodinaNyni)+" : "+Long.toString(minutaNyni)+" : "+Long.toString(sekundaNyni));
        setContentView(casText);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }

    
}

Napadaji me dve moznosti:

1) spatne/vubec  definovana aktivita MainActivity v manifestu

2) Naplneni toho pole trva vic nez cca 5s (tusim, ze jsem nekde cetl, ze zrovna vytvoreni toho calendare neni uplne levne, ale mozna se pletu) a tak to VM androidu zabije z duvodu, ze aplikace skutecne nejakou dobu neodpovida. V tom pripade bych to pole naplnoval a objekty vytvarel v jinem nez UI threadu a v UI to pak nechal jen zobrazit.

Myslel jsi nějak takhle ??

Priblizne tak, ale asi nemuzes menit UI z jineho nez UI threadu (takze nemuzes pouzit .settext ve svem runnable). Da se to resit treba pomoci Handle. Zkus se podivat na handly a runnable do oficialni android dokumentace, tam to je popsane hezky...
