http://i820.photobucket.com/albums/zz130/lestah23/untitled-1_zps33fa9be5.png mio messaggio logcat.
quando eseguo questo codice sul mio telefono. si è verificato un errore. e quando controllo il logcat dice. che ho errori in setImageResource();
cosa devo fare? im un biginner nella programmazione Android :(
grazie in anticipo
Puoi aggiungere alla tua domanda l'errore in logcat. – NaviRamyle
image.setImageResource (R.drawable.may2ndimage); dovrebbe funzionare. Hai pulito il tuo progetto? Progetto -> Clean –
Are ImageView img1, img2 e image, sono tutti in schede Layout ?? –
