android 复制文件 代码,在SDcard中，如何使Android文件的代码移动？_android_开发99编程知识库...

要将文件从一个位置移动到另一个位置，可以使用以下方法：private void moveFile(String inputPath, String outputPath) {

System.out.println(inputPath);

System.out.println(outputPath);

InputStream in = null;

OutputStream out = null;

try {

//create output directory if it doesn't exist

File dir = new File(outputPath);

if (!dir.exists()) {

dir.mkdirs();

}

in = new FileInputStream(inputPath);

out = new FileOutputStream(outputPath);

byte[] buffer = new byte[1024];

int read;

while ((read = in.read(buffer))!= -1) {

out.write(buffer, 0, read);

}

in.close();

in = null;

//write the output file

out.flush();

out.close();

out = null;

//delete the original file

new File(inputPath).delete();

}catch (FileNotFoundException fnfe1) {

Log.e("File not found exception", fnfe1.getMessage());

} catch (Exception e) {

Log.e("Other Exception", e.getMessage());

}

}

要调用这里方法，可以执行以下操作：moveFile(Environment.getExternalStorageDirectory() +"/download/abc.txt", Environment.getExternalStorageDirectory() +"/abc.txt");

你还需要在你的AndroidManifest.xml 中给出写权限
