利用陣列，不多說，直接程式碼

long[] counts= new long[5];

public void GoSystemSetting() {
    System.arraycopy(counts, 1, counts, 0, counts.length - 1);//源陣列  源陣列要複製的起始位置 目的陣列  目的陣列放置的起始位置  複製的長度
counts[counts.length - 1] = SystemClock.uptimeMillis();
    if (counts[0] > SystemClock.uptimeMillis() - 1500) {
        Intent intent
 
 =  new Intent(Settings.ACTION_SETTINGS);
startActivity(intent);
}
}
