メモリーゲームで困っています。それが機能する方法は、「点灯」できるいくつかのボタンが表示されることです。ボタンは特定の順序で点灯し、ユーザーは同じ順序でボタンを押す必要があります。プログラムでレイアウトを作成することができました。現時点では、次のことが起こります。
1: レイアウトはプログラムによって作成され、レイアウト内の各ボタンのテキストは数値に設定されます
2: 一連の番号がダイアログ ボックスでユーザーに表示されます。
3: ユーザーが対応するボタンを押すと、アプリはそれらが正しいことを確認します。
シーケンスを含むダイアログ ボックスを表示する代わりに、ボタンを特定の順序で「点灯」させてシーケンスを「再生」させたい (最終的にはボタンの背景画像を変更したいが、現時点ではテキストを変更しようとしているだけです）。
私はすでにこのスレッドを見つけましたが、問題を解決できませんでした。
現時点では、コードは次のようになっていますが、まったく正しく動作していません。何らかの理由で 3 つのボタンのテキストを一度に「オン」に設定する以下のコードを除いて、すべてが動作します (シーケンスが作成されたとしても) 4 つの異なる数の合計):
pattern.clear();
// generate a sequence and “play” the sequence to the user
for(int i =0; i<sequenceLength;i++){
int x = r.nextInt(numButtons);
pattern.add(x);
Button b = ((Button)findViewById(x));
final Button fb = b;
final Handler h = new Handler();
Timer t = new Timer();
t.schedule(new TimerTask(){
public void run(){
h.post(new Runnable(){
public void run(){
fb.setText(“On”);
}
});
}
}, 1500);
}

アダムを助けてくれてありがとう、それはうまくいった、コードは次のとおりです：
final Timer t = new Timer();
long timeBetweenChangesMs = 1500;
long delay = timeBetweenChangesMs;
for(int i = 0; i < sequenceLength;i++){
final Button b = ((Button)findViewById(pattern.get(i)));
final String bNum = String.valueOf(pattern.get(i));
final Handler h = new Handler();
delay += timeBetweenChangesMs;
t.schedule(new TimerTask(){
public void run(){
h.post(new Runnable(){
public void run(){
b.setText("x");
}
});
}
}, delay);
delay += timeBetweenChangesMs;
t.schedule(new TimerTask(){
public void run(){
h.post(new Runnable(){
public void run(){
b.setText(bNum);
}
});
}
}, (delay));
}
