本文实例讲述了Android编程实现获得内存剩余大小与总大小的方法。分享给大家供大家参考,具体如下:
public class memInfo { // 获得可用的内存 public static long getmem_UNUSED(Context mContext) {long MEM_UNUSED;// 得到ActivityManagerActivityManager am = (ActivityManager) mContext.getSystemService(Context.ACTIVITY_SERVICE);// 创建ActivityManager.MemoryInfo对象 ActivityManager.MemoryInfo mi = new ActivityManager.MemoryInfo();am.getMemoryInfo(mi);// 取得剩余的内存空间 MEM_UNUSED = mi.availMem / 1024;return MEM_UNUSED; } // 获得总内存 public static long getmem_TOLAL() {long mTotal;// /proc/meminfo读出的内核信息进行解释String path = "/proc/meminfo";String content = null;BufferedReader br = null;try { br = new BufferedReader(new FileReader(path), 8); String line; if ((line = br.readLine()) != null) {content = line; }} catch (FileNotFoundException e) { e.printStackTrace();} catch (IOException e) { e.printStackTrace();} finally { if (br != null) {try { br.close();} catch (IOException e) { e.printStackTrace();} }}// beginIndexint begin = content.indexOf(":");// endIndexint end = content.indexOf("k");// 截取字符串信息content = content.substring(begin + 1, end).trim();mTotal = Integer.parseInt(content);return mTotal; }}
希望本文所述对大家Android程序设计有所帮助。
