android开发之配置文件

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;     
    } <br><br>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);     
    }    
  
}
