提问by I DAE
When I click a button,show a file browser,I can choose a folder and return it's path.I get this path to copy file to that path.
当我点击一个按钮，显示一个文件浏览器时，我可以选择一个文件夹并返回它的路径。我得到这个路径来将文件复制到那个路径。
But I have no idea of How I could implement this.

Use intent for that!
为此使用意图！
First start start activity for result like this:
首先开始启动活动，结果如下：
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("file/*");
startActivityForResult(intent, PICKFILE_REQUEST_CODE);
Override this method in your activity, it will get called when activity you just started returns. You can handle result codes such as canceled or successful.
在您的活动中覆盖此方法，它会在您刚开始的活动返回时被调用。您可以处理诸如取消或成功之类的结果代码。
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
String Fpath = data.getDataString();
//TODO handle your request here
super.onActivityResult(requestCode, resultCode, data);
}
Another approach is to use library such as NoNonsense-FilePicker.
另一种方法是使用诸如NoNonsense-FilePicker 之类的库。
