可能有的同学不知道系统已经提供了获取获取SD卡总容量,可用大小,机身内存总容量及可用大小的系统方法,用系统源代码提供的方法可以很简单,方便的获取其大小。这里我把系统源代码中的一个方法贴出来,供大家参考一下:
图片上
图片上红色方框中的代码就是源代码中获取SD卡大小的程序方法。
在这里我整理了一下,我把我整理封装好的方法给大家贴出来:
[java] view plaincopy
class="dp-j" start="1">

-
-
-
- private String getSDTotalSize() {
- File path = Environment.getExternalStorageDirectory();
- StatFs stat = new StatFs(path.getPath());
- long blockSize = stat.getBlockSize();
- long totalBlocks = stat.getBlockCount();
- return Formatter.formatFileSize(MainActivity.this, blockSize * totalBlocks);
- }
-

-
- private String getSDAvailableSize() {
- File path = Environment.getExternalStorageDirectory();
- StatFs stat = new StatFs(path.getPath());
- long blockSize = stat.getBlockSize();
- long availableBlocks = stat.getAvailableBlocks();
- return Formatter.formatFileSize(MainActivity.this, blockSize * availableBlocks);
- }

-
- private String getRomTotalSize() {
- File path = Environment.getDataDirectory();
- StatFs stat = new StatFs(path.getPath());
- long blockSize = stat.getBlockSize();
- long totalBlocks = stat.getBlockCount();
- return Formatter.formatFileSize(MainActivity.this, blockSize * totalBlocks);

- long blockSize = stat.getBlockSize();
- long availableBlocks = stat.getAvailableBlocks();
- return Formatter.formatFileSize(MainActivity.this, blockSize * availableBlocks);
- }
