在将一个文件存储到sd卡上面的时候,一般需要判断sd是否已经挂载才进行操作. 那么如何判断sd卡已经挂载呢? 我们可以使用Android的Environment类,具体使用如下: if(Environment.MEDIA_MOUNTED.equals(Environment.getExternalStorageState())) {//如果已经挂载 //sd卡已经挂载,可以进行读写操作了 } else { //sd未挂载,在此进行提示 } 还有一点,手机上不一定只有一个sd卡,或者手机上的sd卡…

测试从sd卡读1k大小的文件,再写1k大小的文件,由于处理耗时很短,所以循环500次,查看耗时:测试写1k大小的文件,直接在内存构造一个1k的buffer,将这个buffer直接写到文件,同样循环500次,查看耗时. 思路:首先读写文件,建立文件输入输出流,然后将读取的数据直接写入文件,打印时间戳,查看耗时:只写文件,新建一个1k的buffer,然后用文件输出流写入文件,打印时间戳,查看耗时. 直接上代码: package com.example.ghimtim.myapplication; i…
