以下のコードを実行するとすぐに、メディアが60秒間再生され、「残念ながら、YourAPPが停止しました」というエラーでアプリが閉じます。。「bv.setImageResource(R.drawable.play);」を削除した場合 最終的にブロックすると、アプリは完全に機能します。
finallyブロックのbv.setImageResource(R.drawable.play)の問題は何ですか?
これは私のコードです
bv = (ImageButton) findViewById(R.id.imageButton1);
private void mpsleep() {
mp.start();
Thread timer= new Thread(){
public void run(){
try{
for (i =1;i<60;i++){
sleep(1000);//1 second pause
}
}catch(Exception e){
e.printStackTrace();
}finally{
mp.pause();
mp.seekTo(0);
bv.setImageResource(R.drawable.play);
}
}
};
timer.start();
}
