[英]I can't get the first string using sharedPreferences android studio
我正在使用sharedpreferences,我可以將名稱放入.xml文件中,問題是當我嘗試僅獲取名字的ins時,這種情況下我可以看到:D / mySharedPref:[alan,lyneth,daniel,oscar]但我只想看到alan,我怎么能得到我要問的名字
String id = "1";
for(int i = 0; i<getListValueFromKey.size(); i++){
Log.d("mySharedPref", ""+getListValueFromKey);
//in the log window show this:
// D/mySharedPref: [alan, lyneth, daniel, oscar]
}
好的,這是我解決問題的方法:
//add to an Array
Object[] resourceArray = getListValueFromKey.toArray();
//I preferred to leave this var outside to manipulate after
int i;
//I put in the log the first name
Log.d("myName", ""+resourceArray[1]);
//I log the names inside the array
for(i = 0; i<resourceArray.length; i++){
Log.d("mySharedPref", ""+resourceArray[i]);
}
