我的阵列价值为[]={0,0,0,0,0}和视线=“adult”,这两面价值即希望从分享的角度储存和检索。

Assuming that you have a list of preferences for you app called MY_PREFS, I d do this:

SharedPreferences settings = getSharedPreferences(MY_PREFS, 0);
      SharedPreferences.Editor editor = settings.edit();
      editor.putInt("arrayLength",up.size());
      for(int i=0; i<up.size(); i++){
         editor.putInt("up"+String.valueOf(i), up[i]);
      }
      editor.putString("view", "adult");

检索:

   SharedPreferences settings = getSharedPreferences(MY_PREFS, 0);
   int arraySize = settings.getInt("arrayLength");
   int up[] = new int[arraySize];
   for(int i=0; i<arraySize; i++){
      up[i] = settings.getInt("up"+String.valueOf(i));
   }
   String view = settings.getString("view");
问题回答

你们可以通过简单的方式这样做。

SharedPreferences settings = getSharedPreferences("pref_name", 0);
      SharedPreferences.Editor editor = settings.edit();

     String values="";

      for(int i=0; i<yourArray.length; i++){
         values+=","+Integer.toString(yourArray[i]);
      }

      editer.putString("array",values);
      editor.putString("view", "adult");

实现这些价值观,

 SharedPreferences settings = getSharedPreferences("pref_name", 0);

 String[] strArray=settings.getString("array").split(",");
int[] yourArray=new int[strArray.length];

for(int i=0;i<strArray.length;i++){
   yourArray[i]=Integer.toParseInt(strArray[i]);
}

只要我看到你能够直接储存共同的优惠。 然而,你可以使用假体来挽救一个名字不断增加的暗中,并在需要时以同样的方式将其打回另一个阵列。

for(int i=0; i<numInYourArray; i++){
editor.putInt("up"+i, up[i]);
}

如果您确信如何使用共同的参考书,一般见http://mobile.tutsplus.com/tutorials/android/android-application-pviss/“rel=”_>。
