如何存储 HashMap <Integer, String>在android中使用共享偏好? [英] How can I store a HashMap <Integer, String> in android using shared preferences?

问题描述

我通过以下方式创建了一个 HashMap:

I have created a HashMap in the following way:

HashMap<整数、字符串>按钮 = new HashMap<整数，字符串>();

我需要保持这种格式，但是我看到的这个解决方案的每个答案都只适用于 HashMap<String, String>

I need this to remain in this format, however every answer to this solution I have seen only works for HashMap<String, String>

谢谢

推荐答案

嘿嘿，我终于找到了办法:)

Hey I found a way in the end :)

我刚刚更改了必须格式化的 HashMap，然后执行以下操作来保存内容:

I just changed the HashMap I had to format and then did the following to save the contents:

SharedPreferences.Editor editor = getSharedPreferences(PREFS_NAME, 0).edit();
for( Entry entry : backUpCurency_values.entrySet() ) 
editor.putString( entry.getKey(), entry.getValue() );
editor.commit();

以及以下检索HashpMap:

and the following to retrieve the HashpMap:

SharedPreferences prefs = getSharedPreferences(PREFS_NAME, 0);
for( Entry entry : prefs.getAll().entrySet() )
   backUpCurency_values.put( entry.getKey(), entry.getValue().toString() );
