从共享首选项中放置和获取字符串数组

问题描述

我需要在共享首选项中保存一些字符串数组，然后再获取它们.我试过这个:

I need to save on shared preferences some array of Strings and after that to get them.I tried this :

prefsEditor.putString(PLAYLISTS, playlists.toString()); 其中播放列表是一个 String[]

prefsEditor.putString(PLAYLISTS, playlists.toString()); where playlists is a String[]

并得到:

playlist= myPrefs.getString(PLAYLISTS, "playlists"); 其中播放列表是一个 String 但它不起作用.

playlist= myPrefs.getString(PLAYLISTS, "playlists"); where playlist is a String but it is not working.

我该怎么做?有人可以帮我吗?

How can I do this ? Can anyone help me?

提前致谢.

推荐答案

您可以像这样创建自己的数组字符串表示形式:

You can create your own String representation of the array like this:

StringBuilder sb = new StringBuilder();
for (int i = 0; i < playlists.length; i++) {
    sb.append(playlists[i]).append(",");
}
prefsEditor.putString(PLAYLISTS, sb.toString());

然后，当您从 SharedPreferences 获取字符串时，只需像这样解析它:

Then when you get the String from SharedPreferences simply parse it like this:

String[] playlists = playlist.split(",");

这应该可以完成工作.
