Android App中DrawerLayout抽屉效果的菜单编写实例(3)

<?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
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"

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

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); } }

当然比较重要还有styles.xml和colors.xml，具体如下： 

<resources> <style parent="Theme.AppCompat.Light.NoActionBar"> <!--状态栏颜色--> <item>@color/Indigo_colorPrimaryDark</item> <!--Toolbar颜色--> <item>@color/Indigo_colorPrimary</item> <!--返回键样式--> <item>@style/AppTheme.DrawerArrowToggle</item> </style> <style parent="Base.Widget.AppCompat.DrawerArrowToggle"> <item>@android:color/white</item> </style> </resources> <?xml version="1.0" encoding="utf-8"?> <resources> <color>#303f9f</color> <color>#3f51b5</color> <color>#4675FF</color> </resources>
