Android的共享preferences不工作 [英] Android Shared Preferences not working

问题描述

我有一个服务，其中有 4全局静态INT变量和我有BOOT的接收器完全和呼叫事件。我所试图做的是保存这些4个变量，只要调用事件接收器被执行，并在执行BOOT接收器获取它们，但它们都没有工作（当我通过电话重新启动，当然）..另一件事的共享preferences也是有用的，当设备重新启动？的code下面给出

 共享preferences saved_values​​ = this.getShared preferences（
              com.example.app，Context.MODE_PRIVATE）;
    。saved_values​​.edit（）putInt（呼，MyService.callcount）;
    。saved_values​​.edit（）putInt（callend，MyService.callendcount）;
    。saved_values​​.edit（）putInt（网络，MyService.network_count）;
    。saved_values​​.edit（）putInt（振铃，MyService.ringingcount）;
    。saved_values​​.edit（）提交（）;
 

和检索

 共享preferences saved_values​​ = this.getShared preferences（
                  com.example.app，Context.MODE_PRIVATE）;
          MyService.callcount = saved_values​​.getInt（呼，-10）;
          MyService.ringingcount = saved_values​​.getInt（振铃，-10）;
          为MyService。 network_count = saved_values​​.getInt（网络，-10）;
          为MyService。 callendcount = saved_values​​.getInt（callend，-10）;
 

解决方案

我用这个和它的工作对我来说。

有关节能

 共享preferences saved_values​​ = preferenceManager.getDefaultShared preferences（getApplicationContext（））;
 共享preferences.Editor编辑器= saved_values​​.edit（）;
     editor.putInt（算，算）;
             editor.putInt（富，富）;
     editor.commit（）;
 

和检索

 共享preferences saved_values​​ = preferenceManager.getDefaultShared preferences（getApplicationContext（））;

        数= saved_values​​.getInt（计数，-1）;
 

I have a Service in which there are 4 global static int variables and i have a receiver of BOOT COMPLETE and Call event. what I am trying to do is save these 4 variables whenever Call event receiver is execute and Retrieve them when BOOT receiver is executed (of course when I restarted by phone) but Both are not working.. another thing is shared preferences are also useful when device restarts?? the code is given below

    SharedPreferences saved_values = this.getSharedPreferences(
              "com.example.app", Context.MODE_PRIVATE);
    saved_values.edit().putInt("call", MyService.callcount);
    saved_values.edit().putInt("callend",MyService.callendcount);
    saved_values.edit().putInt("network",MyService.network_count);
    saved_values.edit().putInt("ringing",MyService.ringingcount);
    saved_values.edit().commit();

and for retrieving

     SharedPreferences saved_values = this.getSharedPreferences(
                  "com.example.app", Context.MODE_PRIVATE);
          MyService.callcount = saved_values.getInt("call", -10);
          MyService.ringingcount=saved_values.getInt("ringing", -10);
          MyService.    network_count=saved_values.getInt("network", -10);
          MyService.        callendcount=saved_values.getInt("callend", -10);

解决方案

I used this and it worked for me.

For saving

SharedPreferences saved_values = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
 SharedPreferences.Editor editor=saved_values.edit();
     editor.putInt("count",count);
             editor.putInt("foo",foo);
     editor.commit();

and for retrieving

     SharedPreferences saved_values = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());

        count = saved_values.getInt("count", -1);
