Android存储Json到本地，和读取本地Json

/*** 保存json到本地* @param mActivity* @param filename* @param content*/public static File dir = new File(Environment.getExternalStorageDirectory() + "/.Imageloader/json/");public static void saveToSDCard(Activity mActivity, String filename, String content) {String en = Environment.getExternalStorageState();//获取SDCard状态,如果SDCard插入了手机且为非写保护状态  if (en.equals(Environment.MEDIA_MOUNTED)) {try {dir.mkdirs(); //create folders where write filesFile file = new File(dir, filename);OutputStream out = new FileOutputStream(file);out.write(content.getBytes());out.close();
                AppUtils.showToast(mActivity, "保存成功");} catch (Exception e) {e.printStackTrace();
                AppUtils.showToast(mActivity, "保存失败");
            }} else {//提示用户SDCard不存在或者为写保护状态  AppUtils.showToast(mActivity, "SDCard不存在或者为写保护状态");}}/*** 从本地读取json* @param mActivity* @param filename* @param content*/public static String readTextFile(String filePath) {StringBuilder sb = new StringBuilder();try {File file = new File(dir + "/" + filePath);InputStream in = null;in = new FileInputStream(file);int tempbyte;while ((tempbyte = in.read()) != -1) {sb.append((char) tempbyte);}in.close();} catch (Exception e) {e.printStackTrace();}return sb.toString();}
