android开发中常到的配置文件处理方式总结：1.j2se方式：   .properties文件的读取：Java代码  public static Properties getNetConfigProperties() {             Properties props = new Properties();             InputStream in = Utils.class.getResourceAsStream("/netconfig.properties");             try {                 props.load(in);             } catch (IOException e) {                 e.printStackTrace();             }             return props;         } 
使用时： Properties.getProperty("key")   自定义配置文件： Java代码  写入：private static void writeConfiguration(Context context,                 LocaleConfiguration configuration) {             DataOutputStream out = null;             try {                 out = new DataOutputStream(context.openFileOutput(PREFERENCES,                         MODE_PRIVATE));                 out.writeUTF(configuration.locale);                 out.writeInt(configuration.mcc);                 out.writeInt(configuration.mnc);                 out.flush();             } catch (FileNotFoundException e) {                 // Ignore             } catch (IOException e) {                 // noinspection ResultOfMethodCallIgnored                 context.getFileStreamPath(PREFERENCES).delete();             } finally {                 if (out != null) {                     try {                         out.close();                     } catch (IOException e) {                         // Ignore                     }                 }             }         }     Java代码  读取：private static void readConfiguration(Context context,                 LocaleConfiguration configuration) {             DataInputStream in = null;             try {                 in = new DataInputStream(context.openFileInput(PREFERENCES));                 configuration.locale = in.readUTF();                 configuration.mcc = in.readInt();                 configuration.mnc = in.readInt();             } catch (FileNotFoundException e) {                 // Ignore             } catch (IOException e) {                 // Ignore             } finally {                 if (in != null) {                     try {                         in.close();                     } catch (IOException e) {                         // Ignore                     }                 }             }         }   Java代码  private static class LocaleConfiguration {             public String locale;             public int mcc = -1;             public int mnc = -1;         }     Java代码  private static final String PREFERENCES = "launcher.preferences";     2.SharedPreferences：Java代码  public class SharedPreferencesHelper {      SharedPreferences sp;         SharedPreferences.Editor editor;                  Context context;                  public SharedPreferencesHelper(Context c,String name){             context = c;             sp = context.getSharedPreferences(name, 0);             editor = sp.edit();         }         public void putValue(String key, String value){             editor = sp.edit();             editor.putString(key, value);             editor.commit();         }         public String getValue(String key){             return sp.getString(key, null);         }      }
