问题描述
我以下面的方式创建了一个HashMap:
HashMap< Integer,String>按钮= new HashMap< Integer,String>();
我需要这种格式,但是这个解决方案的每个答案都是I只看过 HashMap< String,String>
谢谢
我只是改变了我不得不格式化的HashMap,然后执行以下操作以保存内容:
SharedPreferences.Editor编辑器= getSharedPreferences(PREFS_NAME,0).edit();
for(Entry entry:backUpCurency_values.entrySet())
editor.putString(entry.getKey(),entry.getValue());
editor.commit();
以及以下内容来检索HashpMap:
SharedPreferences prefs = getSharedPreferences(PREFS_NAME,0); (Entry entry:prefs.getAll()。entrySet())
backUpCurency_values.put(entry.getKey(),entry.getValue()。toString());
I have created a HashMap in the following way:
HashMap<Integer, String> buttons = new HashMap<Integer, String>();
I need this to remain in this format, however every answer to this solution I have seen only works for HashMap<String, String>
Thanks
解决方案
Hey I found a way in the end :)
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();
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() );
