Manifest
You need to add the android.permission.WRITE_EXTERNAL_STORAGE permission.
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />Fragment
This library integrates a Fragment called DirectoryChooserFragment; You can use it as floating dialog fragment or regular fragment. You can also pass a default root directory file which will be displayed first. To be notified which directory the user has chosen, you can implement the OnDirectoryChooserFragmentInteraction interface on your host activity (the fragment will automatically register the host activity's interface for you).
public class MainActivity extends ActionBarActivity implements OnDirectoryChooserFragmentInteraction {
File currentRootDirectory = Environment.getExternalStorageDirectory();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
void addDirectoryChooserFragment() {
DialogFragment directoryChooserFragment = DirectoryChooserFragment.newInstance(currentRootDirectory);
getSupportFragmentManager()
.beginTransaction()
.addToBackStack("RDC")
.add(R.id.fragment_host, directoryChooserFragment, "RDC")
.commit();
}
void addDirectoryChooserAsFloatingFragment() {
DialogFragment directoryChooserFragment = DirectoryChooserFragment.newInstance(currentRootDirectory);
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
directoryChooserFragment.show(transaction, "RDC");
}
@Override
public void onEvent(OnDirectoryChosenEvent event) {
File directoryChosenByUser = event.getFile();
}
@Override
public void onEvent(OnDirectoryCancelEvent event) {
}
}
