Question

我有一系列的体力、面积100。我已输入这一阵列中的数据。现在,我想用<条码”储存这种阵列。共有项目。

So my question is that, is it possible to store the entire array of string instead of storing each string individually using SharedPreferences. If so, how that can be done.

The code I have written is used to store data individually using the loop. But I want to store the entire string array without using the loop.

Code I have written for storing individually is

SharedPreferences preferencesWrite  = c.getSharedPreferences("myPreferences", 0);
SharedPreferences.Editor editor  = preferencesWrite.edit();

for(int i=0; i< 100; i++)
{
    editor.putString("dtHistory" + Integer.toString(i), m_dtHistory[i];

}
editor.commit();

Answer 1

共享优惠只允许每个入境点节省单一物品——这一限制得到实施,使用户只能按照名称所示,储存“优惠”——旗帜、插图、编号等等。这样做是为了消除不必要地使用三维物品的qlite数据库。

然而,有一种新的共享方法。优惠(API 11)允许你储存一套插图。 http://developer.android.com/vis/android/content/jointPviss.Editor.html#putStringSet%28java.lang.String,%20java.util.Set%3Cjava.lang.String%3E%29"rel=“nofollow”

Yes it,s Possible to Store array in form of String

你们应当这样做:

    SharedPreferences preferencesWrite  = c.getSharedPreferences("myPreferences", 0);
    SharedPreferences.Editor editor  = preferencesWrite.edit();

     Gson gson = new Gson();
     ArrayList<ModelClass>favorites = new ArrayList<>();

     String jsonFavorites = gson.toJson(favorites);
     editor.putString("your sharedPref NTT", jsonFavorites);
     editor.apply();
