*したがって、sleep メソッドを保持する Thread があり、stop() メソッドを使用してプログラムを停止しようとするとプログラムがクラッシュするため、これが問題だと思います。ユーザーが戻るボタン (ハードウェアの戻るボタン) を押したときにスレッドを完全に停止しようとしています。これについてどうすればよいですか?スリープメソッド以外のものを使用する必要がありますか? *
Thread timer2 = new Thread() { // Threads - do multiple things
public void run() {
try {
sleep(5000); // 5000 mil secs = 5 secs . sleeps thread
} catch (InterruptedException e) {
e.printStackTrace();
} finally {
cdt2.start();
}
}
};
timer2.start(); // starts thread
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
timer1.stop(); //error
timer2.stop(); //error
cdt.cancel();
cdt2.cancel();
Intent menu = new Intent("android.intent.action.MENU");
startActivity(menu);
return true;
}
return false;
}
