保存：
public static boolean saveArray() {
SharedPrefernces sp=SharedPrefernces.getDefaultSharedPrefernces(this);
SharedPrefernces.Editor mEdit1= sp.edit();
mEdit1.putInt("Status_size",sKey.size()); /*sKey is an array*/
for(int i=0;i<sKey.size();i++) {
mEdit1.remove("Status_" + i);
mEdit1.putString("Status_" + i, sKey.get(i));
}
return mEdit1.commit();
}
取值：
public static void loadArray(Context mContext) {
Shared Preferences mSharedPreference1=PreferenceManager.getDefaultSharedPreferences(mContext);
sKey.clear();
int size = mSharedPreference1.getInt("Status_size", 0);
for(int i=0;i<size;i++) {
sKey.add(mSharedPreference1.getString("Status_" + i, null));
}
}
