Question

在Android開發中，我們如何通過編碼來擦除整個SD卡？我需要通過我的應用程序格式化SD卡內容。

我找到了答案， 只是調用wipeMemoryCard（）;

public void wipeMemoryCard() { 
    try { 
     File deleteMatchingFile = new File(Environment.getExternalStorageDirectory().toString()); 
     File[] filenames = deleteMatchingFile.listFiles(); 
     if (filenames != null && filenames.length > 0) { 
      for (File tempFile : filenames) { 
        if (tempFile.isDirectory()) { 
         wipeDirectory(tempFile.toString()); 
        } else { 
         tempFile.delete() 
        } 
      } 
     } 
    } catch (Exception e) { 
    } 
} 

private void wipeDirectory(String name) { 
    try { 
     File directoryFile = new File(name); 
     File[] filenames = directoryFile.listFiles(); 
     if (filenames != null && filenames.length > 0) { 
      for (File tempFile : filenames) { 
        if (tempFile.isDirectory()) { 
         wipeDirectory(tempFile.toString()); 
        } else { 
         tempFile.delete() 
        } 
      } 
     } 
    } catch (Exception e) { 
    } 
}
