DrawerLayout
DrawerLayout
DrawerLayout是SupportLibrary包中实现了侧滑菜单效果的控件,可以说drawerLayout是因为第三方控件如MenuDrawer等的出现之后,google借鉴而出现的产物。drawerLayout分为侧边菜单和主内容区两部分,侧边菜单可以根据手势展开与隐藏(drawerLayout自身特性),主内容区的内容可以随着菜单的点击而变化(这需要使用者自己实现)。
DrawerLayout基本用法
drawerLayout的使用很方便,使用drawerLayout的要点如下:
**1.**drawerLayout其实是一个布局控件,跟LinearLayout等控件是一种东西,但是drawerLayout带有滑动的功能。只要按照drawerLayout的规定布局方式写完布局,就能有侧滑的效果。
<!-- A DrawerLayout is intended to be used as the top-level content view using match_parent for both width and height to consume the full space available. -->
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- As the main content view, the view below consumes the entire
space available using match_parent in both dimensions. -->
<FrameLayout
android:id="@+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<!-- android:layout_gravity="start" tells DrawerLayout to treat
this as a sliding drawer on the left side for left-to-right
languages and on the right side for right-to-left languages.
The drawer is given a fixed width in dp and extends the full height of
the container. A solid background is used for contrast
with the content view. -->
<ListView
android:id="@+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="@android:color/transparent"
android:dividerHeight="0dp"
android:background="#111"/>
</android.support.v4.widget.DrawerLayout>
其中:DrawerLayout最好为界面的根布局,官网是这样说的,否则可能会出现触摸事件被屏蔽的问题;主内容区的布局代码要放在侧滑菜单布局的前面, 因为XML 顺序意味着按 z序(层叠顺序)排序,并且抽屉式导航栏必须位于内容顶部;侧滑菜单部分的布局(这里是ListView)必须设置layout_gravity属性,他表示侧滑菜单是在左边还是右边,而且如果不设置在打开关闭抽屉的时候会报错,设置了layout_gravity=”start/left”的视图才会被认为是侧滑菜单。
2.**drawerLayout左侧菜单(或者右侧)的展开与隐藏可以被DrawerLayout.DrawerListener的实现监听到,这样你就可以在菜单展开与隐藏反生的时刻做一些希望做的事情,比如更新actionbar菜单等。如果你的activity有actionbar的话,还是建议你用**ActionBarDrawerToggle来监听,ActionBarDrawerToggle实现了DrawerListener,所以他能做DrawerListener可以做的任何事情,同时他还能将drawerLayout的展开和隐藏与actionbar的app 图标关联起来,当展开与隐藏的时候图标有一定的平移效果,点击图标的时候还能展开或者隐藏菜单。
mDrawerToggle = new ActionBarDrawerToggle(
this, /* host Activity */
mDrawerLayout, /* DrawerLayout object */
R.drawable.ic_drawer, /* nav drawer image to replace 'Up' caret */
R.string.drawer_open, /* "open drawer" description for accessibility */
R.string.drawer_close /* "close drawer" description for accessibility */
) {
public void onDrawerClosed(View view) {
getActionBar().setTitle(mTitle);
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
public void onDrawerOpened(View drawerView) {
getActionBar().setTitle(mDrawerTitle);
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
3.何为侧边菜单
侧边菜单其实只是一个普通的View,一般里面装的是ListView,看起来就像菜单,他完全可以是一个button,textView等等。虽然称为菜单,但跟Activity的菜单形式是两码事,Activity的菜单只需要在资源文件中定义好,就能按照固定的形式显示出来。而drawerLayout的侧边菜单显示成什么样完全是取决于你自己,同样点击事件也完全由你自己去写。如下代码所示我们的侧边菜单是一个ListView显示的:
mDrawerList.setAdapter(new ArrayAdapter<String>(this,
R.layout.drawer_list_item, mPlanetTitles));
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
/* The click listner for ListView in the navigation drawer */
private class DrawerItemClickListener implements ListView.OnItemClickListener {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
selectItem(position);
}
}
private void selectItem(int position) {
// update the main content by replacing fragments
Fragment fragment = new PlanetFragment();
Bundle args = new Bundle();
args.putInt(PlanetFragment.ARG_PLANET_NUMBER, position);
fragment.setArguments(args);
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction().replace(R.id.content_frame, fragment).commit();
// update selected item and title, then close the drawer
mDrawerList.setItemChecked(position, true);
setTitle(mPlanetTitles[position]);
mDrawerLayout.closeDrawer(mDrawerList);
}
4.在代码中主动展开与隐藏侧边菜单。
在点击侧边菜单选项的时候我们往往需要隐藏菜单来显示整个菜单对应的内容。DrawerLayout.closeDrawer方法用于隐藏侧边菜单,DrawerLayout.openDrawer方法用于展开侧边菜单(参见第3点中的代码部分)
5.如何在菜单展开或者隐藏的时候更新activity的menu
上面的的第2点讲到DrawerLayout.DrawerListener监听展开与隐藏事件,在监听的回调方法中我们用invalidateOptionsMenu通知activity重绘menu,然后activity就有机会在onPrepareOptionsMenu方法中更新menu元素的显示与隐藏
代码:
/* Called whenever we call invalidateOptionsMenu() */
@Override
public boolean onPrepareOptionsMenu(Menu menu) {
// If the nav drawer is open, hide action items related to the content view
boolean drawerOpen = mDrawerLayout.isDrawerOpen(mDrawerList);
menu.findItem(R.id.action_websearch).setVisible(!drawerOpen);
return super.onPrepareOptionsMenu(menu);
}
6.如何让app图标点击的时候能够展开或者隐藏侧边菜单。
一般的想法是在activity的onOptionsItemSelected方法中判断点击事件是否来自于app图标,然后用DrawerLayout.closeDrawer和DrawerLayout.openDrawer来隐藏与展开(参见第4点:在代码中主动展开与隐藏侧边菜单)。但是drawerLayout提供了更优雅的方式:使用ActionBarDrawerToggle的onOptionsItemSelected方法。该方法activity的onOptionsItemSelected方法中根据传递进来的menu
item做了上面我们在“一般想法”中提到的事情。用官方的说法是”ActionBarDrawerToggle will take care of this”。我们只需这样做就ok了:
Activity中:
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// The action bar home/up actionshould open or close the drawer.
// ActionBarDrawerToggle will takecare of this.
if(mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
……….//处理其他菜单点击事件
returnsuper.onOptionsItemSelected(item);
}
如果不仔细阅读官方文档,估计我们很难看出(mDrawerToggle.onOptionsItemSelected(item)在这里的作用。这也是我刚开始最疑惑的地方。
7. drawerLayout与Fragment是什么关系?
我们看到很多使用drawerLayout的代码中都同时使用了Fragment,这会造成误解,以为使用drawerLayout必须用到Fragment,其实这是错误的,使用Fragment是因为在侧滑菜单被点击的时候,主内容区如果内容比较复杂,用Fragment去填充会更容易,如果你的主内容区只是一个简单的字符串,只想在不同菜单点击的时候更新一下字符串的内容,我觉得没必要用Fragment。不过官方的例子其实中,Fragment所做的就是更新字符串内容这么简单。
最后我们来看看一个完整的drawerLayout的例子,来源于官方网站的demo,代码中反映了上述我们提到的所有要点:

/**
* This example illustrates a common usage of the DrawerLayout widget
* in the Android support library.
* <p/>
* <p>When a navigation (left) drawer is present, the host activity should detect presses of
* the action bar's Up affordance as a signal to open and close the navigation drawer. The
* ActionBarDrawerToggle facilitates this behavior.
* Items within the drawer should fall into one of two categories:</p>
* <p/>
* <ul>
* <li><strong>View switches</strong>. A view switch follows the same basic policies as
* list or tab navigation in that a view switch does not create navigation history.
* This pattern should only be used at the root activity of a task, leaving some form
* of Up navigation active for activities further down the navigation hierarchy.</li>
* <li><strong>Selective Up</strong>. The drawer allows the user to choose an alternate
* parent for Up navigation. This allows a user to jump across an app's navigation
* hierarchy at will. The application should treat this as it treats Up navigation from
* a different task, replacing the current task stack using TaskStackBuilder or similar.
* This is the only form of navigation drawer that should be used outside of the root
* activity of a task.</li>
* </ul>
* <p/>
* <p>Right side drawers should be used for actions, not navigation. This follows the pattern
* established by the Action Bar that navigation should be to the left and actions to the right.
* An action should be an operation performed on the current contents of the window,
* for example enabling or disabling a data overlay on top of the current content.</p>

DrawerLayout官网介绍
Toolbar + DrawerLayout
效果:
1. 首先需要添加appcompat-v7支持
如果是在Android Studio 1.0 RC4上创建的项目,默认已经添加了appcompat-v7支持了,如果不是最新版AS则需要在build.gradle中添加如下代码:
dependencies {
...//其他代码
compile 'com.android.support:appcompat-v7:21.0.2'
}
添加完成后需要同步一下gradle
2. 添加Toolbar
由于Toolbar是继承自View,所以可以像其他标准控件一样直接主布局文件添加Toolbar,但是为了提高Toolbar的重用效率,可以在layout创建一个custom_toolbar.xml代码如下:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/tl_custom"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:minHeight="?attr/actionBarSize"
android:popupTheme="@style/ThemeOverlay.AppCompat.Light"
app:theme="@style/ThemeOverlay.AppCompat.ActionBar">
</android.support.v7.widget.Toolbar>
说明:
android.support.v7.widget.Toolbar -
当然如果只在Lollipop中可以直接使用Toolbar而不需要加上v7支持
xmlns:app -
自定义xml命名控件,在AS中可以直接指定res-auto而不需要使用完整包名
android:background 和 android:minHeight 均可以在styles.xml中声明
3. 添加DrawerLayout
和Toolbar类似,为了提高代码重用效率,可以在layout中创建一个custom_drawerlayout.xml代码如下:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/dl_left"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!--主布局-->
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="@+id/iv_main"
android:layout_width="100dp"
android:layout_height="100dp" />
</LinearLayout>
<!--侧滑菜单-->
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#fff"
android:layout_gravity="start">
<ListView
android:id="@+id/lv_left_menu"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:divider="@null"
android:text="DrawerLayout" />
</LinearLayout>
</android.support.v4.widget.DrawerLayout>
Drawerlayout标签中有两个子节点,一个是左边菜单,一个是主布局,另外需要在左边菜单起始位置设置为android:layout_gravity=”start”
4. 实现activity_main.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".MainActivity">
<!--Toolbar-->
<include layout="@layout/custom_toolbar" />
<!--DrawerLayout-->
<include layout="@layout/custom_drawerlayout" />
</LinearLayout>
直接使用include标签,简洁明了
5. 完善Java代码
public class MainActivity extends ActionBarActivity {
//声明相关变量
private Toolbar toolbar;
private DrawerLayout mDrawerLayout;
private ActionBarDrawerToggle mDrawerToggle;
private ListView lvLeftMenu;
private String[] lvs = {"List Item 01", "List Item 02", "List Item 03", "List Item 04"};
private ArrayAdapter arrayAdapter;
private ImageView ivRunningMan;
private AnimationDrawable mAnimationDrawable;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
findViews(); //获取控件
//京东RunningMan动画效果,和本次Toolbar无关
mAnimationDrawable = (AnimationDrawable) ivRunningMan.getBackground();
mAnimationDrawable.start();
toolbar.setTitle("Toolbar");//设置Toolbar标题
toolbar.setTitleTextColor(Color.parseColor("#ffffff")); //设置标题颜色
setSupportActionBar(toolbar);
getSupportActionBar().setHomeButtonEnabled(true); //设置返回键可用
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
//创建返回键,并实现打开关/闭监听
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, toolbar, R.string.open, R.string.close) {
@Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
mAnimationDrawable.stop();
}
@Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
mAnimationDrawable.start();
}
};
mDrawerToggle.syncState();
mDrawerLayout.setDrawerListener(mDrawerToggle);
//设置菜单列表
arrayAdapter = new ArrayAdapter(this, android.R.layout.simple_list_item_1, lvs);
lvLeftMenu.setAdapter(arrayAdapter);
}
private void findViews() {
ivRunningMan = (ImageView) findViewById(R.id.iv_main);
toolbar = (Toolbar) findViewById(R.id.tl_custom);
mDrawerLayout = (DrawerLayout) findViewById(R.id.dl_left);
lvLeftMenu = (ListView) findViewById(R.id.lv_left_menu);
}
}
6. 当然比较重要还有styles.xml和colors.xml,具体如下
<resources>
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!--状态栏颜色-->
<item name="colorPrimaryDark">@color/Indigo_colorPrimaryDark</item>
<!--Toolbar颜色-->
<item name="colorPrimary">@color/Indigo_colorPrimary</item>
<!--返回键样式-->
<item name="drawerArrowStyle">@style/AppTheme.DrawerArrowToggle</item>
</style>
<style name="AppTheme.DrawerArrowToggle" parent="Base.Widget.AppCompat.DrawerArrowToggle">
<!--三根小横线的颜色-->
<item name="color">@android:color/white</item>
</style>
</resources>
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="Indigo_colorPrimaryDark">#303f9f</color>
<color name="Indigo_colorPrimary">#3f51b5</color>
<color name="Indigo_nav_color">#4675FF</color>
</resources>
最终效果如下:
