我想将文件从内部存储移动到SD卡。我尝试使用Environment.getExternalStorageDirectory()
,但它仅移动内部存储。
我使用了以下代码:
ContextCompat.getExternalFilesDirs(mActivity, null)[0]
但是它在包文件夹中移动
/storage/emulated/0/Android/data/com.unzipdemo/files/MyFileStorage/SampleFile.txt
我想在特定的文件夹名称中移动文件。您能帮我解决吗?
答案 0 :(得分:0)
尝试使用此方法copyDirectoryOneLocationToAnotherLocation()
将内部文件值作为源位置和外部文件路径传递 作为目标位置
public static void copyDirectoryOneLocationToAnotherLocation(File sourceLocation, File
targetLocation)
throws IOException {
if (sourceLocation.isDirectory()) {
if (!targetLocation.exists()) {
targetLocation.mkdir();
}
String[] children = sourceLocation.list();
for (int i = 0; i < sourceLocation.listFiles().length; i++) {
copyDirectoryOneLocationToAnotherLocation(new File(sourceLocation, children[i]),
new File(targetLocation, children[i]));
}
} else {
InputStream in = new FileInputStream(sourceLocation);
OutputStream out = new FileOutputStream(targetLocation);
// Copy the bits from instream to outstream
byte[] buf = new byte[1024];
int len;
while ((len = in.read(buf)) > 0) {
out.write(buf, 0, len);
}
in.close();
out.close();
}
}
注意:-复制后,删除源文件
