选择项目后如何关闭导航抽屉？

Question

I have implemented a navigation drawer and everything functions properly. The navigation drawer contains a listview and when an item is selected, the main fragment is replaced properly.

This is the onClickListener code:

mDrawerListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        HeaderViewListAdapter headerView = (HeaderViewListAdapter) parent.getAdapter();
        AccountAdapter adapter = (AccountAdapter) headerView.getWrappedAdapter();
        Cursor cursor = adapter.getCursor();

        if(cursor != null && cursor.moveToPosition(position)){
            ((NavigationDrawerCallbacks) getActivity()).onNavigationDrawerItemSelected(cursor.getLong(cursor.getColumnIndex(ID_COLUMN)));
        }
    }
});

And in my activity, the onNavigationDrawerItemSelected method is like this:

@Override
public void onNavigationDrawerItemSelected(long accountId) {
    // update the main content by replacing fragments
    FragmentManager fragmentManager = getSupportFragmentManager();
    fragmentManager.beginTransaction()
            .replace(R.id.mainFragment, AccountDetailFragment.newInstance(accountId))
            .commit();
}

As I said, this functions, but the navigation drawer remains open. It's a hassle for the user to have to select an account from the listview and then have to close the drawer to see the main fragment, so how can I have it close automatically, so that when an item is selected the only visible element is the main fragment (and everything inside of it)?

Answer 1

使用Drawer View或Drawer's Gravity作为参数，在DrawerLayout对象上调用closeDrawer() 。

Answer 2

You need to call the closeDrawer inside the onItemClick, when the Drawer Layout is not null.

    if (mDrawerLayout != null) {
        mDrawerLayout.closeDrawer(mFragmentContainerView);
    }
