考虑 bigInts 是的BigInteger [] 你想从 preference ：

 的BigInteger [] bigInts =新的BigInteger [N];
设置＆LT;字符串＆GT;设置=新的HashSet＆LT;字符串＆GT;（）;

对于（BigInteger的BIGINT：bigInts）{
    set.add（bigInt.toString（））;
}

//存入preference
共享preference.Editor编辑= getShared preference（getPackageName（），Context.MODE_PRIVATE）.edit（）;
editor.putStringSet（bigints，设置）;

//获取BitInteger []由preference
共享preference preF = getShared preference（getPackageName（），Context.MODE_PRIVATE）;

设置＆LT;字符串＆GT;设置= pref.getStringSet（bigints，新的HashSet＆LT;字符串＆GT;（））;
诠释计数= set.size（）;

的String [] =可疑交易报告新的String [统计]
BigInteger的[] bigInts =新的BigInteger [统计]
set.toArray序列（STR）;

的for（int i = 0; I＆LT;计数;我++）{
    bitInts [我] =新的BigInteger序列（STR [I]）;
}
 

I want to save/load a BigInteger array into/from the SharedPreferences. How can it be done?

For example for the following array:

private BigInteger[] dataCreatedTimes = new BigInteger[20];

Consider bigInts is the BigInteger[] you want from Preference:

BigInteger[] bigInts = new BigInteger[n];
Set<String> set = new HashSet<String>();

for(BigInteger bigInt : bigInts) {
    set.add(bigInt.toString());
}

//store into Preference
SharedPreference.Editor editor = getSharedPreference(getPackageName(), Context.MODE_PRIVATE).edit();
editor.putStringSet("bigints", set);

//get BitInteger[] from Preference
SharedPreference pref = getSharedPreference(getPackageName(), Context.MODE_PRIVATE);

Set<String> set = pref.getStringSet("bigints", new HashSet<String>());
int count = set.size();

String[] strs = new String[count];
BigInteger[] bigInts= new BigInteger[count];
set.toArray(strs);

for(int i = 0; i < count; i++) {
    bitInts[i] = new BigInteger(strs[i]);
}
