You have to create 2 QFileSystemModel, one will show the directories and the other the files. To change the view of the QListView you must use the clicked signal, using the QModelIndex you set the new rootIndex.

import sys

from PyQt5.QtWidgets import *
from PyQt5.QtCore import *

class Widget(QWidget):
    def __init__(self, *args, **kwargs):
        QWidget.__init__(self, *args, **kwargs)
        hlay = QHBoxLayout(self)
        self.treeview = QTreeView()
        self.listview = QListView()
        hlay.addWidget(self.treeview)
        hlay.addWidget(self.listview)

        path = QDir.rootPath()

        self.dirModel = QFileSystemModel()
        self.dirModel.setRootPath(QDir.rootPath())
        self.dirModel.setFilter(QDir.NoDotAndDotDot | QDir.AllDirs)

        self.fileModel = QFileSystemModel()
        self.fileModel.setFilter(QDir.NoDotAndDotDot |  QDir.Files)

        self.treeview.setModel(self.dirModel)
        self.listview.setModel(self.fileModel)

        self.treeview.setRootIndex(self.dirModel.index(path))
        self.listview.setRootIndex(self.fileModel.index(path))

        self.treeview.clicked.connect(self.on_clicked)

    def on_clicked(self, index):
        path = self.dirModel.fileInfo(index).absoluteFilePath()
        self.listview.setRootIndex(self.fileModel.setRootPath(path))


if __name__ == '__main__':
    app = QApplication(sys.argv)
    w = Widget()
    w.show()
    sys.exit(app.exec_())
