咱们用的时候完全用不上啊。怎么修改呢

上面的两个发现了有哪里改变了吗。下面我们来讲解（抛开官网）

 headerResult = new AccountHeaderBuilder()
                .withActivity(this)
                .withTranslucentStatusBar(true)
                .withHeaderBackground(R.drawable.header)
                .withSelectionFirstLine("1")
                .withSelectionSecondLine("2")
//                .withOnlyMainProfileImageVisible(true)
//                .withOnlySmallProfileImagesVisible(true)
                .withSelectionListEnabled(false)

很明显可以看到你们需要的 然后就是最后一个行就是隐藏那个小箭头的作用。，这样的改变相信大家就会有很好的作用了

西面开始唠叨的环节，学渣带你扣，那咱么那就开始扣~~~~

  final IProfile profile = new ProfileDrawerItem().withName("Mike Penz").withEmail("mikepenz@gmail.com").withIcon("https://avatars3.githubusercontent.com/u/1476232?v=3&s=460").withIdentifier(100);
        final IProfile profile2 = new ProfileDrawerItem().withName("Demo User").withEmail("demo@github.com").withIcon("https://avatars2.githubusercontent.com/u/3597376?v=3&s=460").withIdentifier(101);
        final IProfile profile3 = new ProfileDrawerItem().withName("Max Muster").withEmail("max.mustermann@gmail.com").withIcon(R.drawable.profile2).withIdentifier(102);
        final IProfile profile4 = new ProfileDrawerItem().withName("Felix House").withEmail("felix.house@gmail.com").withIcon(R.drawable.profile3).withIdentifier(103);
        final IProfile profile5 = new ProfileDrawerItem().withName("Mr. X").withEmail("mister.x.super@gmail.com").withIcon(R.drawable.profile4).withIdentifier(104);
        final IProfile profile6 = new ProfileDrawerItem().withName("Batman").withEmail("batman@gmail.com").withIcon(R.drawable.profile5).withIdentifier(105);

上面这个就是官网给的接口去实例化一个对象，这个对象就是上面的最早的那些有emil图片名字那些。但是那些对我们日常的设计来说并没有什么用处。但是我们还是要了解一下。这个思路怎么。来作为我们一种结束的积累

image.png

直接粘贴了这个就是实例化的那个对象。下面那些都是一些方法来设置页面的值。重点不在这里，我们先来了解第一眼我们看到的

ProfileDrawerItem extends AbstractDrawerItem<ProfileDrawerItem, ProfileDrawerItem.ViewHolder> implements IProfile<ProfileDrawerItem>, Tagable<ProfileDrawerItem>, Typefaceable<ProfileDrawerItem> {

我曹第一眼。好复杂。

image.png

下面让我们静下心来好好分析一下。

implements IProfile<ProfileDrawerItem>, Tagable<ProfileDrawerItem>, Typefaceable<ProfileDrawerItem>

实现了三个接口。并且接口自带泛型，我们来分析一个这三个接口有什么用处

public interface IProfile<T> extends IIdentifyable<T> {
    T withName(String name);

    StringHolder getName();

    T withEmail(String email);

    StringHolder getEmail();

    T withIcon(Drawable icon);

    T withIcon(Bitmap bitmap);

    T withIcon(@DrawableRes int iconRes);

    T withIcon(String url);

    T withIcon(Uri uri);

    T withIcon(IIcon icon);

    ImageHolder getIcon();

    T withSelectable(boolean selectable);

    boolean isSelectable();
}

很直观就是一个设置图片什么的。针对各种来源。

public interface Tagable<T> {
    T withTag(Object tag);

    Object getTag();
}

这个接口也很直观。就是设置tag ，。相信用过listview的都知道。但是在ProfileDrawerItem中并没有，为什么呢？在父类已经实现这个方法了。（有需要的同学可以看我的其他的系列讲泛型的）

public interface Typefaceable<T> {
    T withTypeface(Typeface typeface);

    Typeface getTypeface();
}

设置字体的

ProfileDrawerItem 通过这几个接口来实现那些公共的方法。下面我们来看看他的父类AbstractDrawerItem 这个类从名字我们就可以看出来用图抽象抽屉item。

public abstract class AbstractDrawerItem<T, VH extends RecyclerView.ViewHolder> implements IDrawerItem<T, VH>, Selectable<T>, Tagable<T> {

从他实现的接口上来看他三个接口的三个作用分别是
IDrawerItem

public interface IDrawerItem<T, VH extends RecyclerView.ViewHolder> extends IItem<T, VH>, IExpandable<T, IDrawerItem>, ISubItem<IDrawerItem, IDrawerItem> {

    Object getTag();

    boolean isEnabled();

    boolean isSelected();

    T withSetSelected(boolean selected);

    boolean isSelectable();

    T withSelectable(boolean selectable);

    int getType();

    int getLayoutRes();

    View generateView(Context ctx);

    View generateView(Context ctx, ViewGroup parent);

    VH getViewHolder(ViewGroup parent);

    void unbindView(VH holder);

    void bindView(VH holder, List<Object> payloads);

    boolean equals(long id);

就像listview一样设置是不是点击连接等各种状态，另外仔细看他还继承了三个接口，都是一系列各种状态的接口

然后我们看一下

  // Create the AccountHeader
        headerResult = new AccountHeaderBuilder()
                .withActivity(this)
                .withTranslucentStatusBar(true)
                .withHeaderBackground(R.drawable.header)
                .withSelectionFirstLine("1")
                .withSelectionSecondLine("2")
//                .withOnlyMainProfileImageVisible(true)
//                .withOnlySmallProfileImagesVisible(true)
                .withSelectionListEnabled(false)
//                .addProfiles(
//                        profile,
//                        profile2,
//                        profile3,
//                        profile4,
//                        profile5,
//                        profile6,
//                        //don't ask but google uses 14dp for the add account icon in gmail but 20dp for the normal icons (like manage account)
//                        new ProfileSettingDrawerItem().withName("Add Account").withDescription("Add new GitHub Account").withIcon(new IconicsDrawable(this, GoogleMaterial.Icon.gmd_plus).actionBar().paddingDp(5).colorRes(R.color.material_drawer_primary_text)).withIdentifier(PROFILE_SETTING),
//                        new ProfileSettingDrawerItem().withName("Manage Account").withIcon(GoogleMaterial.Icon.gmd_settings).withIdentifier(100001)
//                )
                .withOnAccountHeaderListener(new AccountHeader.OnAccountHeaderListener() {
                    @Override
                    public boolean onProfileChanged(View view, IProfile profile, boolean current) {
                        //sample usage of the onProfileChanged listener
                        //if the clicked item has the identifier 1 add a new profile ;)
                        if (profile instanceof IDrawerItem && profile.getIdentifier() == PROFILE_SETTING) {
                            int count = 100 + headerResult.getProfiles().size() + 1;
                            IProfile newProfile = new ProfileDrawerItem().withNameShown(true).withName("Batman" + count).withEmail("batman" + count + "@gmail.com").withIcon(R.drawable.profile5).withIdentifier(count);
                            if (headerResult.getProfiles() != null) {
                                //we know that there are 2 setting elements. set the new profile above them ;)
                                headerResult.addProfile(newProfile, headerResult.getProfiles().size() - 2);
                            } else {
                                headerResult.addProfiles(newProfile);
                            }
                        }

                        //false if you have not consumed the event and it should close the drawer
                        return false;
                    }
                })
                .withSavedInstance(savedInstanceState)
                .build();

这些方法就是最字头对

image.png

这些事件的一个处理，还有背景等一些显示。文章开头那些常用的样式就可以按照我一开发的那样去写
AccountHeaderBuilder 类
builder涉及模式

里面的大部分方法都是设定一下我们从build去看

public AccountHeader build() {
        // if the user has not set a accountHeader use the default one :D
        if (mAccountHeaderContainer == null) {
            withAccountHeader(-1);
        }

        // get the header view within the container
        mAccountHeader = mAccountHeaderContainer.findViewById(R.id.material_drawer_account_header);

        //the default min header height by default 148dp
        int defaultHeaderMinHeight = mActivity.getResources().getDimensionPixelSize(R.dimen.material_drawer_account_header_height);
        int statusBarHeight = UIUtils.getStatusBarHeight(mActivity, true);

        // handle the height for the header
        int height;
        if (mHeight != null) {
            height = mHeight.asPixel(mActivity);
        } else {
            if (mCompactStyle) {
                height = mActivity.getResources().getDimensionPixelSize(R.dimen.material_drawer_account_header_height_compact);
            } else {
                //calculate the header height by getting the optimal drawer width and calculating it * 9 / 16
                height = (int) (DrawerUIUtils.getOptimalDrawerWidth(mActivity) * AccountHeader.NAVIGATION_DRAWER_ACCOUNT_ASPECT_RATIO);

                //if we are lower than api 19 (>= 19 we have a translucentStatusBar) the height should be a bit lower
                //probably even if we are non translucent on > 19 devices?
                if (Build.VERSION.SDK_INT < 19) {
                    int tempHeight = height - statusBarHeight;
                    //if we are lower than api 19 we are not able to have a translucent statusBar so we remove the height of the statusBar from the padding
                    //to prevent display issues we only reduce the height if we still fit the required minHeight of 148dp (R.dimen.material_drawer_account_header_height)
                    //we remove additional 8dp from the defaultMinHeaderHeight as there is some buffer in the header and to prevent to large spacings
                    if (tempHeight > defaultHeaderMinHeight - UIUtils.convertDpToPixel(8, mActivity)) {
                        height = tempHeight;
                    }
                }
            }
        }

        // handle everything if we have a translucent status bar which only is possible on API >= 19
        if (mTranslucentStatusBar && Build.VERSION.SDK_INT >= 21) {
            mAccountHeader.setPadding(mAccountHeader.getPaddingLeft(), mAccountHeader.getPaddingTop() + statusBarHeight, mAccountHeader.getPaddingRight(), mAccountHeader.getPaddingBottom());
            //in fact it makes no difference if we have a translucent statusBar or not. we want 9/16 just if we are not compact
            if (mCompactStyle) {
                height = height + statusBarHeight;
            } else if ((height - statusBarHeight) <= defaultHeaderMinHeight) {
                //if the height + statusBar of the header is lower than the required 148dp + statusBar we change the height to be able to display all the data
                height = defaultHeaderMinHeight + statusBarHeight;
            }
        }

        //set the height for the header
        setHeaderHeight(height);

        // get the background view
        mAccountHeaderBackground = (ImageView) mAccountHeaderContainer.findViewById(R.id.material_drawer_account_header_background);
        // set the background
        ImageHolder.applyTo(mHeaderBackground, mAccountHeaderBackground, DrawerImageLoader.Tags.ACCOUNT_HEADER.name());

        if (mHeaderBackgroundScaleType != null) {
            mAccountHeaderBackground.setScaleType(mHeaderBackgroundScaleType);
        }

        // get the text color to use for the text section
        int textColor = ColorHolder.color(mTextColor, mActivity, R.attr.material_drawer_header_selection_text, R.color.material_drawer_header_selection_text);

        // set the background for the section
        if (mCompactStyle) {
            mAccountHeaderTextSection = mAccountHeader;
        } else {
            mAccountHeaderTextSection = mAccountHeaderContainer.findViewById(R.id.material_drawer_account_header_text_section);
        }

        mAccountHeaderTextSectionBackgroundResource = UIUtils.getSelectableBackgroundRes(mActivity);
        handleSelectionView(mCurrentProfile, true);

        // set the arrow :D
        mAccountSwitcherArrow = (ImageView) mAccountHeaderContainer.findViewById(R.id.material_drawer_account_header_text_switcher);
        mAccountSwitcherArrow.setImageDrawable(new IconicsDrawable(mActivity, MaterialDrawerFont.Icon.mdf_arrow_drop_down).sizeRes(R.dimen.material_drawer_account_header_dropdown).paddingRes(R.dimen.material_drawer_account_header_dropdown_padding).color(textColor));

        //get the fields for the name
        mCurrentProfileView = (BezelImageView) mAccountHeader.findViewById(R.id.material_drawer_account_header_current);
        mCurrentProfileName = (TextView) mAccountHeader.findViewById(R.id.material_drawer_account_header_name);
        mCurrentProfileEmail = (TextView) mAccountHeader.findViewById(R.id.material_drawer_account_header_email);

        //set the typeface for the AccountHeader
        if (mNameTypeface != null) {
            mCurrentProfileName.setTypeface(mNameTypeface);
        } else if (mTypeface != null) {
            mCurrentProfileName.setTypeface(mTypeface);
        }

        if (mEmailTypeface != null) {
            mCurrentProfileEmail.setTypeface(mEmailTypeface);
        } else if (mTypeface != null) {
            mCurrentProfileEmail.setTypeface(mTypeface);
        }

        mCurrentProfileName.setTextColor(textColor);
        mCurrentProfileEmail.setTextColor(textColor);

        mProfileFirstView = (BezelImageView) mAccountHeader.findViewById(R.id.material_drawer_account_header_small_first);
        mProfileSecondView = (BezelImageView) mAccountHeader.findViewById(R.id.material_drawer_account_header_small_second);
        mProfileThirdView = (BezelImageView) mAccountHeader.findViewById(R.id.material_drawer_account_header_small_third);

这是build的一部分方法想看就看不想看不看也行就是一些高度的设置等。字体什么。

最有用图的就是后半段

     calculateProfiles();

        //process and build the profiles
        buildProfiles();

        // try to restore all saved values again
        if (mSavedInstance != null) {
            int selection = mSavedInstance.getInt(AccountHeader.BUNDLE_SELECTION_HEADER, -1);
            if (selection != -1) {
                //predefine selection (should be the first element
                if (mProfiles != null && (selection) > -1 && selection < mProfiles.size()) {
                    switchProfiles(mProfiles.get(selection));
                }
            }
        }

        //everything created. now set the header
        if (mDrawer != null) {
            mDrawer.setHeader(mAccountHeaderContainer, mPaddingBelowHeader, mDividerBelowHeader);
        }

        //forget the reference to the activity
        mActivity = null;

        return new AccountHeader(this);

这段主要就是设置那些emil 等那些 但是个人觉得这些没必要。策划菜单还没见过那么设计的 上面设计这些主要就是Head头部分。 并且设置一些监听。 剩下的 我们来看重点的部分。

result = new DrawerBuilder() 
设计模式同上。 咱们主要就其中的方法进行分析
 前300行代码不解释 绑定页面。 toolbar  等一些

开始分析方法。
1 如何改变下面内容的颜色

.withSliderBackgroundColor(getResources().getColor(R.color.colorPrimaryDark))
.withSliderBackgroundColorRes(R.color.colorPrimaryDark) 两个方法一样

image.png

.withSliderBackgroundDrawableRes(R.drawable.header)
withSliderBackgroundDrawable设置背景图片的

image.png

withDrawerWidthPx 设置侧滑出来的宽度一般不需要设置

 .withDrawerGravity(GravityCompat.END) 设置右滑或者左滑

image.png

.withAccountHeader(headerResult) //set the AccountHeader we created earlier for the header
这个很简单就是把我们刚才设置HEad 显示出来

.withActionBarDrawerToggleAnimated(true) 一個动态效果左侧按钮

image.png

按钮有一个平滑的过渡

.withScrollToTopAfterClick(true) 这个方法也很好理解。在你点击一个item之后在打开这个侧滑的时候你想要是直接拉到底的还是在最上面、

withSelectedItemByPosition 一开始选择的默认选择的

addDrawerItems 增加内容的各种内容

好了到这里就差不多了大部分的样式都是可以满足的。如果有不同需要的。可以查看源码
