保存Bundle对象到共享preference [英] Saving Bundle object into shared preference

问题描述

我有2个活动

活动1

活性2

活动1：

 意向意图=新意图（Activity1.this，Acivity2.class）;
束B =新包（）;
b.putParcelableArrayList（actionArray，（ArrayList的＆所述;?延伸Parcelable＆GT）AllListArray.get（0））;
b.putParcelableArrayList（comedyArray，（ArrayList的＆所述;?延伸Parcelable＆GT）AllListArray.get（1））;
b.putParcelableArrayList（loveArray，（ArrayList的＆所述;?延伸Parcelable＆GT）AllListArray.get（2））;
b.putParcelableArrayList（classicsArray，（ArrayList的＆所述;?延伸Parcelable＆GT）AllListArray.get（3））;
b.putParcelableArrayList（familyArray，（ArrayList的＆所述;?延伸Parcelable＆GT）AllListArray.get（4））;intent.putExtras（二）;
startActivity（意向）;
 

活性2：

活性2：

 公开名单＆LT;电影及GT; actionArray;
     公开名单＆LT;电影及GT; comedyArray;
     公开名单＆LT;电影及GT; loveArray;
     公开名单＆LT;电影及GT; classicsArray;
     公开名单＆LT;电影及GT; familyArray;
    公共无效的onCreate（捆绑savedInstanceState）{
        super.onCreate（savedInstanceState）;
        捆绑recdData = getIntent（）getExtras（）。
        如果（recdData！= NULL）{
            actionArray = recdData.getParcelableArrayList（actionArray）;
            comedyArray = recdData.getParcelableArrayList（comedyArray）;
            loveArray = recdData.getParcelableArrayList（loveArray）;
            classicsArray = recdData.getParcelableArrayList（classicsArray）;
            familyArray = recdData.getParcelableArrayList（familyArray）;
        }
    }
 

我的要求是存储捆绑（recdData）到共享preferences 的活性2？
可以在任何一个可以帮助我？

解决方案

  preferences = mActivity.getShared preferences（
                    分享preference_demo，Context.MODE_PRIVATE）; 地图＆LT;字符串，字符串＆GT; demoarraylist =新的HashMap＆LT;字符串，字符串＆GT;（）;
    demoarraylist.put（actionArray，行动）;
    demoarraylist.put（comedyArray，喜剧）;
    demoarraylist.put（lovearray，爱）;
    demoarraylist.put（classicArray，经典）;
    demoarraylist.put（familyArray，家庭）;共享preferences.Editor编辑器= preferences.edit（）;
                对于（进入＆LT;字符串，字符串＆GT;项：demoarraylist.entrySet（））{
                    editor.putString（entry.getKey（），entry.getValue（））;
                }
             editor.commit（）;
 

把上面的code把你的第一个活动。

和低于code是把你的第二次活动。

 地图＆LT;字符串，字符串＆GT; demoarraylist =新的HashMap＆LT;字符串，字符串＆GT;（）;
 共享preferences preferences = activity.getShared preferences（
                    分享preference_demo，Context.MODE_PRIVATE）;
            对于（进入＆LT;弦乐，＆GT;条目：？preferences.getAll（）的entrySet（））{
                demoarraylist.put（entry.getKey（），entry.getValue（）的toString（））;
            }
。迭代myVeryOwnIterator = demoarraylist.keySet（）迭代（）;
        而（myVeryOwnIterator.hasNext（））{
            字符串键=（字符串）myVeryOwnIterator.next（）;
            字符串值=（字符串）MapListUserStatus.get（密钥）;
}
 

I have 2 Activities

Activity1

Activity2

Activity1:

Intent intent= new Intent(Activity1.this,Acivity2.class);
Bundle b=new Bundle();      
b.putParcelableArrayList("actionArray", (ArrayList<? extends Parcelable>) AllListArray.get(0)); 
b.putParcelableArrayList("comedyArray", (ArrayList<? extends Parcelable>) AllListArray.get(1));
b.putParcelableArrayList("loveArray", (ArrayList<? extends Parcelable>) AllListArray.get(2));
b.putParcelableArrayList("classicsArray", (ArrayList<? extends Parcelable>) AllListArray.get(3));
b.putParcelableArrayList("familyArray", (ArrayList<? extends Parcelable>) AllListArray.get(4));

intent.putExtras(b);             
startActivity(intent); 

Activity2:

Activity2:

 public List<Movie> actionArray;
     public List<Movie> comedyArray;
     public List<Movie> loveArray;
     public List<Movie> classicsArray;
     public List<Movie> familyArray;
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Bundle recdData = getIntent().getExtras();
        if(recdData!=null) {
            actionArray=recdData.getParcelableArrayList("actionArray");
            comedyArray=recdData.getParcelableArrayList("comedyArray");
            loveArray=recdData.getParcelableArrayList("loveArray");
            classicsArray=recdData.getParcelableArrayList("classicsArray");
            familyArray=recdData.getParcelableArrayList("familyArray");
        }
    }

My Requirement is to Store the Bundle(recdData) into Sharedpreferences in Activity2? Could any one help me?

解决方案

preferences = mActivity.getSharedPreferences(
                    SharePreference_demo, Context.MODE_PRIVATE); 



 Map<String, String> demoarraylist= new HashMap<String, String>();
    demoarraylist.put("actionArray", "action");
    demoarraylist.put("comedyArray", "comedy");
    demoarraylist.put("lovearray", "love");
    demoarraylist.put("classicArray", "classic");
    demoarraylist.put("familyArray", "family");



SharedPreferences.Editor editor = preferences.edit();
                for (Entry<String, String> entry : demoarraylist.entrySet()) {
                    editor.putString(entry.getKey(), entry.getValue());
                }
             editor.commit();

put above code put in your 1st activity.

and below code is put in your 2nd activity.

 Map<String, String> demoarraylist= new HashMap<String, String>();


 SharedPreferences preferences = activity.getSharedPreferences(
                    SharePreference_demo, Context.MODE_PRIVATE);
            for (Entry<String, ?> entry : preferences.getAll().entrySet()) {
                demoarraylist.put(entry.getKey(), entry.getValue().toString());
            }


Iterator myVeryOwnIterator = demoarraylist.keySet().iterator();
        while (myVeryOwnIterator.hasNext()) {
            String key = (String) myVeryOwnIterator.next();
            String value = (String) MapListUserStatus.get(key);
}
