Question

我正在使用mikepenz's Material Drawer。我试图实现的是为抽屉实现一个监听器，所以当它被打开时，我可以向API发出请求并使用从API返回的数据更新标头。我有两个问题： 1.当我尝试实现监听器时，它不会被触发。我的听众看起来像这样：

result.setOnDrawerNavigationListener(new Drawer.OnDrawerNavigationListener(){
            @Override
            public boolean onNavigationClickListener(View view) {
                //If the drawer is not yet opened but at the end of the action it will be
                if (!result.isDrawerOpen())
                {
                    getCurrentUser(savedInstanceState);
                    return true;
                }
                else
                    onBackPressed();
                return false;
            }
        });

考虑到我有一个自定义标题，我填充如下：

final View sidebarHeader = factory.inflate（R.layout.sidebar_header，null）; TextView用户名=（TextView）sidebarHeader.findViewById（R.id.username）; username.setText（u.getUsername（））; CircleImageView profilePic =（CircleImageView）sidebarHeader.findViewById（R.id.profilePic）; Picasso.with（this）.load（BuildConfig.BASE_API_URL + profilePictureUrl）.fit（）。placeholder（R.drawable.default_user_icon）.error（R.drawable.default_user_icon）.into（profilePic）;
```
    TextView email = (TextView) sidebarHeader.findViewById(R.id.email);
    email.setText(u.getEmail());
```

更新信息的最佳方法是什么？这种方法是正确的吗？

result.updateName(R.id.username, new StringHolder(response.body().getUsername()));
                String profilePictureUrl = response.body().getProfilePicture();
                CircleImageView profilePic = (CircleImageView) findViewById(R.id.profilePic);
                Picasso.with(getApplicationContext()).load(BuildConfig.BASE_API_URL + profilePictureUrl).fit().placeholder(R.drawable.default_user_icon).error(R.drawable.default_user_icon).into(profilePic);
                drawer.updateIcon(R.id.profilePic, new ImageHolder(profilePictureUrl));

或者我应该重新生成标题？

抽屉格式：

result = new DrawerBuilder()
                .withActivity(this)
                .withHeader(sidebarHeader)
                .withToolbar(toolbar)
                .addDrawerItems(
                        new PrimaryDrawerItem().withIdentifier(0).withName(R.string.dashboard).withIcon(FontAwesome.Icon.faw_tachometer),
                        new PrimaryDrawerItem().withIdentifier(1).withName(R.string.point_of_sale).withIcon(FontAwesome.Icon.faw_file_text_o),
                        new ExpandableDrawerItem().withName(R.string.ecommerce).withIcon(FontAwesome.Icon.faw_shopping_cart).withSubItems(

                        ),
                        new PrimaryDrawerItem().withIdentifier(3).withName(R.string.clients).withIcon(FontAwesome.Icon.faw_briefcase),

                        ),
                        new PrimaryDrawerItem().withIdentifier(8).withName(R.string.settings).withIcon(FontAwesome.Icon.faw_cog),

                                new SecondaryDrawerItem().withIdentifier(10).withName(R.string.orders)
                        )
                )
                .addStickyDrawerItems(new PrimaryDrawerItem().withIdentifier(11).withName(R.string.sign_out).withIcon(FontAwesome.Icon.faw_lock))
                .withOnDrawerItemClickListener(new Drawer.OnDrawerItemClickListener() {
                    @Override
                    public boolean onItemClick(View view, int position, IDrawerItem drawerItem) {
                        // do something with the clicked item :D
                        if (drawerItem != null) {
                            Fragment fragment = null;
                            switch ((int) drawerItem.getIdentifier()){
                                case 0:
                                    fragment = new DashboardFragment();
                                    break;
                                case 8:
                                    fragment = new SettingsFragment();

                                    Intent i = new Intent(getApplicationContext(), SplashScreenActivity.class);
                                    MainProvider.sharedInstance().logOut(MainActivity.this);
                                    Toast.makeText(MainActivity.this, "Logged Out", Toast.LENGTH_SHORT).show();
                                    startActivity(i);
                                    break;

                            }
                            if(fragment != null){
                                getSupportFragmentManager().beginTransaction().replace(R.id.mainFragment,(android.support.v4.app.Fragment) fragment, Integer.toString((int) drawerItem.getIdentifier())).addToBackStack(null).commit();
                            }
                        }
                        return false;
                    }
                })
                .withSavedInstance(savedInstanceState)
                .build();

感谢您的时间！

更新

result.updateName(R.id.username, new StringHolder(response.body().getData().getUsername()));
                String profilePictureUrl = response.body().getData().getSettings().getProfilePicture();
                CircleImageView profilePic = (CircleImageView) findViewById(R.id.profilePic);
                Picasso.with(getApplicationContext()).load(BuildConfig.BASE_API_URL + profilePictureUrl).fit().placeholder(R.drawable.default_user_icon).error(R.drawable.default_user_icon).into(profilePic);
                result.updateIcon(R.id.profilePic, new ImageHolder(profilePictureUrl));
                result.updateName(R.id.email, new StringHolder(response.body().getData().getEmail()));

Answer 1

要收听onDrawerOpened，只需通过OnDrawerListener添加DrawerBuilder即可 https://github.com/mikepenz/MaterialDrawer/blob/develop/library/src/main/java/com/mikepenz/materialdrawer/DrawerBuilder.java#L1150

此侦听器提供您需要的所有功能

public interface OnDrawerListener {
    /**
     * @param drawerView
     */
    void onDrawerOpened(View drawerView);

    /**
     * @param drawerView
     */
    void onDrawerClosed(View drawerView);

    /**
     * @param drawerView
     * @param slideOffset
     */
    void onDrawerSlide(View drawerView, float slideOffset);
}

如果您有自定义标头，则直接更新视图是正确的方法。所以你的第一种方法似乎很好。

根据@ mikepenez的回答，我找到了一个解决方案：

new DrawerBuilder()
                .withActivity(this)
                .withHeader(sidebarHeader)
                .withToolbar(toolbar)
                .addDrawerItems(
                        new PrimaryDrawerItem().withIdentifier(0).withName(R.string.dashboard).withIcon(FontAwesome.Icon.faw_tachometer),
                        new PrimaryDrawerItem().withIdentifier(1).withName(R.string.point_of_sale).withIcon(FontAwesome.Icon.faw_file_text_o),
                        new ExpandableDrawerItem().withName(R.string.ecommerce).withIcon(FontAwesome.Icon.faw_shopping_cart).withSubItems(
                                new SecondaryDrawerItem().withIdentifier(2).withName(R.string.shops)
                        ),
                        new PrimaryDrawerItem().withIdentifier(3).withName(R.string.clients).withIcon(FontAwesome.Icon.faw_briefcase),
                        new PrimaryDrawerItem().withIdentifier(4).withName(R.string.invoices).withIcon(FontAwesome.Icon.faw_list_alt),
                        new PrimaryDrawerItem().withIdentifier(5).withName(R.string.payment_requests).withIcon(R.drawable.payment_request),
                        new ExpandableDrawerItem().withName(R.string.catalog).withIcon(FontAwesome.Icon.faw_folder_open).withSubItems(
                                new SecondaryDrawerItem().withIdentifier(6).withName(R.string.products),
                                new SecondaryDrawerItem().withIdentifier(7).withName(R.string.categories)
                        ),
                        new PrimaryDrawerItem().withIdentifier(8).withName(R.string.settings).withIcon(FontAwesome.Icon.faw_cog),
                        new ExpandableDrawerItem().withName(R.string.reports).withIcon(FontAwesome.Icon.faw_list_ol).withSubItems(
                                new SecondaryDrawerItem().withIdentifier(9).withName(R.string.transactions),
                                new SecondaryDrawerItem().withIdentifier(10).withName(R.string.orders)
                        )
                )
                .addStickyDrawerItems(new PrimaryDrawerItem().withIdentifier(11).withName(R.string.sign_out).withIcon(FontAwesome.Icon.faw_lock))
                .withOnDrawerItemClickListener(new Drawer.OnDrawerItemClickListener() {
                    @Override
                    public boolean onItemClick(View view, int position, IDrawerItem drawerItem) {
                        // do something with the clicked item :D
                        if (drawerItem != null) {
                            Fragment fragment = null;
                            switch ((int) drawerItem.getIdentifier()){
                                case 0:
                                    fragment = new DashboardFragment();
                                    break;
                                case 8:
                                    fragment = new SettingsFragment();
                                    break;
                                case 11:
                                    Intent i = new Intent(getApplicationContext(), SplashScreenActivity.class);
                                    MainProvider.sharedInstance().logOut(MainActivity.this);
                                    Toast.makeText(MainActivity.this, "Logged Out", Toast.LENGTH_SHORT).show();
                                    startActivity(i);
                                    break;

                            }
                            if(fragment != null){
                                getSupportFragmentManager().beginTransaction().replace(R.id.mainFragment,(android.support.v4.app.Fragment) fragment, Integer.toString((int) drawerItem.getIdentifier())).addToBackStack(null).commit();
                            }
                        }
                        return false;
                    }
                })
                    .withOnDrawerListener(new Drawer.OnDrawerListener() {
                        @Override
                        public void onDrawerOpened(View drawerView) {
                            getCurrentUser();
                        }

                        @Override
                        public void onDrawerClosed(View drawerView) {

                        }

                        @Override
                        public void onDrawerSlide(View drawerView, float slideOffset) {
                        }
                    })

                    .withSavedInstance(savedInstanceState)
                .build();

遗憾的是更新标题不适用于updateName（）或updateIcon（）方法，但我偶然发现我只需更改用户名并从我的自定义标题布局发送电子邮件TextViews，如下所示：

View sidebarHeader = drawer.getHeader();
//Update header username
TextView username = (TextView) sidebarHeader.findViewById(R.id.username);
username.setText(response.body().getData().getUsername());
//Update header email
TextView email = (TextView) sidebarHeader.findViewById(R.id.email);
email.setText(response.body().getData().getEmail());
//Update header profile picture
String profilePictureUrl = response.body().getData().getSettings().getProfilePicture();
CircleImageView profilePic = (CircleImageView) sidebarHeader.findViewById(R.id.profilePic);
Picasso.with(getApplicationContext()).load(BuildConfig.BASE_API_URL + profilePictureUrl).fit().placeholder(R.drawable.default_user_icon).error(R.drawable.default_user_icon).into(profilePic);

Material Drawer setOnDrawerNavigationListener用于在打开抽屉时运行方法
