Android Properties 存储
1.初始化
1 private static void initProperties(){ 2 File logFile = new File(Constants.PROGRESS_PROPERTIES); 3 props = new Properties(); 4 if(!logFile.exists()){ 5 //创建并初始化配置文件 6 FileUtils.createFolder(Constants.BASEPATH + "Config");// 先创建文件夹 7 RootUtil.execAsRoot("echo \"\" > " + Constants.PROGRESS_PROPERTIES, "chmod 666 " + Constants.PROGRESS_PROPERTIES); 8 persistent(-1, -1, -1, -1, "-1", "-1" , 0, 0, "-1", "-1", 0, 0, "-1", "-1", "-1", "-1", "-1", "-1"); 9 }else{ 10 loadProgress(props, Constants.PROGRESS_PROPERTIES); 11 } 12 }
2.存储
1 /** 2 * 持久化 4 * @param channel 5 * @param app 6 * @return 7 */ 8 public static boolean persistent(int channel, int app){ 14 19 props.setProperty(KEY_CHANNEL, String.valueOf(channel)); 20 props.setProperty(KEY_APP, String.valueOf(app));36 37 FileOutputStream fos = null; 38 try{ 39 fos = new FileOutputStream(Constants.PROGRESS_PROPERTIES); 40 props.store(fos, null); 41 return true; 42 }catch(Exception e){ 43 return false; 44 }finally{ 45 if(fos != null){ 46 try 47 { 48 fos.close(); 49 } 50 catch(Exception e){ 51 e.printStackTrace(); 52 } 53 } 54 } 55 }
3.获取持久化值
1 /** 2 * 获取属性值 3 * @param key 4 * @return 5 */ 6 private static int getValue(String key){ 7 try{ 8 if(props == null){ 9 initProperties(); 10 } 11 return Integer.parseInt(props.getProperty(key)); 12 }catch(Exception e){ 13 e.printStackTrace(); 14 } 15 return -1; 16 } 17 18 /** 19 * 获取属性值 20 * @param key 21 * @return 22 */ 23 private static String getValueForStr(String key){ 24 try{ 25 if(props == null){ 26 initProperties(); 27 } 28 return props.getProperty(key); 29 }catch(Exception e){ 30 e.printStackTrace(); 31 } 32 return "-1"; 33 }
其中包含获取assets文件夹目录下的配置文件：
1 /** 2 * 获取配置文件中的value 3 * @param url 路径 4 * @param param 参数 5 * @param getFlag 访问标识 0:SD , 1 Assets 6 * @return 7 */ 8 public String getValue(String url, String param, int getFlag) { 9 String result = null; 10 switch(getFlag){ 11 case 0: 12 result = getProperties(url).getProperty(param); 13 break; 14 case 1: 15 result = getPropertiesByAssets(url).getProperty(param); 16 break; 17 } 18 19 try { 20 if (fis != null) { 21 fis.close(); 22 } 23 if(in != null){ 24 in.close(); 25 } 26 } catch (Exception e) { 27 e.printStackTrace(); 28 } 29 return result == null ? "" : result; 30 }
4.当初始化好的文件，重新加载。
1 /** 2 * 加载属性 3 * @param props 4 */ 5 private static void loadProgress(Properties props, String file){ 6 FileInputStream fis = null; 7 try{ 8 fis = new FileInputStream(file); 9 props.load(fis);13 if(props.get(KEY_CHANNEL) == null){ 14 props.setProperty(KEY_CHANNEL, String.valueOf(-1)); 15 } 16 if(props.get(KEY_APP) == null){ 17 props.setProperty(KEY_APP, String.valueOf(-1)); 18 }64 }catch(Exception e){ 65 e.printStackTrace(); 66 }finally{ 67 if(fis != null){ 68 try 69 { 70 fis.close(); 71 } 72 catch(Exception e){ 73 e.printStackTrace(); 74 } 75 } 76 } 77 }
