很多APP都有侧滑菜单的功能,部分APP左右都是侧滑菜单~SlidingMenu 这个开源项目可以很好帮助我们实现侧滑功能,如果对SlidingMenu 还不是很了解的童鞋,可以参考下本篇博客。将侧滑菜单引入项目的方式很多中,本博客先通过例子介绍各种引入方式,然后给大家展示个实例:主布局ViewPager,左右各一个侧滑菜单的用法,差不多已经能满足大部分应用的需求了。关于常用属性,在文章末尾介绍。
1、在Activity中通过SlidingMenu构造方法,直接设置侧滑菜单
package com.zhy.zhy_slidemenu_demo; import androidappActivity; import androidosBundle; import comjeremyfeinsteinslidingmenulibSlidingMenu; public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { superonCreate(savedInstanceState); setContentView(Rlayoutactivity_main); // configure the SlidingMenu SlidingMenu menu = new SlidingMenu(this); menusetMode(SlidingMenuLEFT); // 设置触摸屏幕的模式 menusetTouchModeAbove(SlidingMenuTOUCHMODE_FULLSCREEN); menusetShadowWidthRes(Rdimenshadow_width); menusetShadowDrawable(Rdrawableshadow); // 设置滑动菜单视图的宽度 menusetBehindOffsetRes(Rdimenslidingmenu_offset); // 设置渐入渐出效果的值 menusetFadeDegree(35f); /** * SLIDING_WINDOW will include the Title/ActionBar in the content * section of the SlidingMenu, while SLIDING_CONTENT does not */ menuattachToActivity(this, SlidingMenuSLIDING_CONTENT); //为侧滑菜单设置布局 menusetMenu(Rlayoutleftmenu); } }
效果图:
是不是特别简单~几行代码搞定~哈~
2、通过把Activity继承SlidingActivity
a、继承SlidingActivity
b、然后在onCreate中setBehindContentView(R.layout.leftmenu); 设置侧滑菜单的布局
c、通过getSlidingMenu()得到SlidingMenu对象,然后设置样式
package com.zhy.zhy_slidemenu_demo02; import androidosBundle; import comjeremyfeinsteinslidingmenulibSlidingMenu; import comjeremyfeinsteinslidingmenulibappSlidingActivity; public class MainActivity extends SlidingActivity { @Override public void onCreate(Bundle savedInstanceState) { superonCreate(savedInstanceState); setContentView(Rlayoutactivity_main); setBehindContentView(Rlayoutleftmenu); // configure the SlidingMenu SlidingMenu menu = getSlidingMenu(); menusetMode(SlidingMenuLEFT); // 设置触摸屏幕的模式 menusetTouchModeAbove(SlidingMenuTOUCHMODE_FULLSCREEN); menusetShadowWidthRes(Rdimenshadow_width); menusetShadowDrawable(Rdrawableshadow); // 设置滑动菜单视图的宽度 menusetBehindOffsetRes(Rdimenslidingmenu_offset); // 设置渐入渐出效果的值 menusetFadeDegree(35f); /** * SLIDING_WINDOW will include the Title/ActionBar in the content * section of the SlidingMenu, while SLIDING_CONTENT does not */ // menuattachToActivity(this, SlidingMenuSLIDING_CONTENT); // menusetMenu(Rlayoutleftmenu); } }
效果图和第一种方式一样~是不是也很简单~~
3、将SlidingMenu当作普通控件
可以把SlidingMenu作为普通的view,然后在布局中声明,丧心病狂的玩~下面看个例子:
<RelativeLayout xmlns:android="http://schemasandroidcom/apk/res/android" xmlns:tools="http://schemasandroidcom/tools" android:id="@+id/id_main_ly" android:layout_width="match_parent" android:layout_height="match_parent" > <LinearLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="30dp" android:layout_marginTop="30dp" > <comjeremyfeinsteinslidingmenulibSlidingMenu xmlns:sliding="http://schemasandroidcom/apk/res-auto" android:id="@+id/slidingmenulayout" android:layout_width="120dp" android:layout_height="170dp" android:background="#ffffffff" sliding:behindOffset="0dp" sliding:behindScrollScale="1" sliding:fadeDegree="3" sliding:fadeEnabled="true" sliding:touchModeAbove="fullscreen" sliding:viewAbove="@layout/pic" /> </LinearLayout> </RelativeLayout>
我们SlidingMenu作为普通View在布局文件中设置了布局,并且设置了viewAbove的值为另一个布局。
下面看pic布局:
<?xml version="1.0" encoding="utf-8"?> <ImageView xmlns:android="http://schemasandroidcom/apk/res/android" android:layout_width="120dp" android:layout_height="170dp" android:src="@drawable/zhy" />
就是一张妹子图片。
最后看主Activity:
package comzhyzhy_slidemenu_demo03; import androidappActivity; import androidosBundle; import androidviewView; import androidviewViewOnClickListener; import comjeremyfeinsteinslidingmenulibSlidingMenu; public class MainActivity extends Activity { private SlidingMenu mLeftMenu; @Override protected void onCreate(Bundle savedInstanceState) { superonCreate(savedInstanceState); setContentView(Rlayoutactivity_main); mLeftMenu = (SlidingMenu) findViewById(Ridslidingmenulayout); // configure the SlidingMenu // SlidingMenu menu = new SlidingMenu(this); mLeftMenusetMode(SlidingMenuLEFT); // 设置触摸屏幕的模式 mLeftMenusetShadowWidthRes(Rdimenshadow_width); mLeftMenusetShadowDrawable(Rdrawableshadow); mLeftMenusetMenu(Rlayoutleftmenu); mLeftMenusetOnClickListener(new OnClickListener() { @Override public void onClick(View v) { if (mLeftMenuisMenuShowing()) mLeftMenutoggle(); } }); // 设置滑动菜单视图的宽度 // 设置渐入渐出效果的值 /** * SLIDING_WINDOW will include the Title/ActionBar in the content * section of the SlidingMenu, while SLIDING_CONTENT does not */ } }
效果图:
通过SlidingMenu给图片设置一个滑动展示介绍,你也可以滑动显示任何东西,下载、分享按钮什么的。图片很多的时候不知道效率咋样,可以这么玩,但是不建议哈~
4、SlidingMenu设置左右侧滑菜单例子
上面介绍的3个方法,SlidingMenu的布局中控件的事件都需要写在Activity中,这样代码比较臃肿,一般会使用Fragment作为侧滑菜单的布局容器。
核心代码:
Fragment leftMenuFragment = new MenuLeftFragment(); setBehindContentView(Rlayoutleft_menu_frame); getSupportFragmentManager()beginTransaction() replace(Ridid_left_menu_frame, leftMenuFragment)commit(); SlidingMenu menu = getSlidingMenu(); menusetMode(SlidingMenuLEFT_RIGHT); // 设置触摸屏幕的模式 menusetTouchModeAbove(SlidingMenuTOUCHMODE_MARGIN);
先给侧滑菜单通过 setBehindContentView(R.layout.left_menu_frame);设置一个布局,此布局中只有一个FrameLayout,然后使用FragmentManager将Fragment替换掉此Fragment,这样这个Fragment就作为我们侧滑菜单的布局了,我们的事件处理代码也可以写在Fragement中,而不是Activity中。
下面看具体例子:
首先分别是左右两边的两个Fragment:
MenuLeftFragment
package comzhyzhy_slidemenu_demo04; import javautilArrays; import javautilList; import androidosBundle; import androidsupportvappFragment; import androidviewLayoutInflater; import androidviewView; import androidviewViewGroup; import androidwidgetArrayAdapter; import androidwidgetListAdapter; import androidwidgetListView; public class MenuLeftFragment extends Fragment { private View mView; private ListView mCategories; private List<String> mDatas = Arrays asList("聊天", "发现", "通讯录", "朋友圈", "订阅号"); private ListAdapter mAdapter; @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { if (mView == null) { initView(inflater, container); } return mView; } private void initView(LayoutInflater inflater, ViewGroup container) { mView = inflaterinflate(Rlayoutleft_menu, container, false); mCategories = (ListView) mView findViewById(Ridid_listview_categories); mAdapter = new ArrayAdapter<String>(getActivity(), androidRlayoutsimple_list_item_1, mDatas); mCategoriessetAdapter(mAdapter); } }
左边的侧滑布局就是一个ListView,代码比较简单~
MenuRightFragment
package comzhyzhy_slidemenu_demo04; import androidosBundle; import androidsupportvappFragment; import androidviewLayoutInflater; import androidviewView; import androidviewViewGroup; public class MenuRightFragment extends Fragment { private View mView; @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { if(mView == null) { mView = inflaterinflate(Rlayoutright_menu, container, false); } return mView ; } }
右边的侧滑菜单的Fragment,加载了一个布局,没有做任何事件处理~
最后是MainActivity
package comzhyzhy_slidemenu_demo04; import javautilArrayList; import javautilList; import androidosBundle; import androidsupportvappFragment; import androidsupportvappFragmentPagerAdapter; import androidsupportvviewViewPager; import androidviewView; import androidviewWindow; import comjeremyfeinsteinslidingmenulibSlidingMenu; import comjeremyfeinsteinslidingmenulibappSlidingFragmentActivity; public class MainActivity extends SlidingFragmentActivity { private ViewPager mViewPager; private FragmentPagerAdapter mAdapter; private List<Fragment> mFragments = new ArrayList<Fragment>(); @Override public void onCreate(Bundle savedInstanceState) { superonCreate(savedInstanceState); thisrequestWindowFeature(WindowFEATURE_NO_TITLE); setContentView(Rlayoutactivity_main); // 初始化SlideMenu initRightMenu(); // 初始化ViewPager initViewPager(); } private void initViewPager() { mViewPager = (ViewPager) findViewById(Ridid_viewpager); MainTab01 tab01 = new MainTab01(); MainTab02 tab02 = new MainTab02(); MainTab03 tab03 = new MainTab03(); mFragmentsadd(tab01); mFragmentsadd(tab02); mFragmentsadd(tab03); /** * 初始化Adapter */ mAdapter = new FragmentPagerAdapter(getSupportFragmentManager()) { @Override public int getCount() { return mFragmentssize(); } @Override public Fragment getItem(int arg0) { return mFragmentsget(arg0); } }; mViewPagersetAdapter(mAdapter); } private void initRightMenu() { Fragment leftMenuFragment = new MenuLeftFragment(); setBehindContentView(Rlayoutleft_menu_frame); getSupportFragmentManager()beginTransaction() replace(Ridid_left_menu_frame, leftMenuFragment)commit(); SlidingMenu menu = getSlidingMenu(); menusetMode(SlidingMenuLEFT_RIGHT); // 设置触摸屏幕的模式 menusetTouchModeAbove(SlidingMenuTOUCHMODE_MARGIN); menusetShadowWidthRes(Rdimenshadow_width); menusetShadowDrawable(Rdrawableshadow); // 设置滑动菜单视图的宽度 menusetBehindOffsetRes(Rdimenslidingmenu_offset); // 设置渐入渐出效果的值 menusetFadeDegree(35f); // menusetBehindScrollScale(0f); menusetSecondaryShadowDrawable(Rdrawableshadow); //设置右边(二级)侧滑菜单 menusetSecondaryMenu(Rlayoutright_menu_frame); Fragment rightMenuFragment = new MenuRightFragment(); getSupportFragmentManager()beginTransaction() replace(Ridid_right_menu_frame, rightMenuFragment)commit(); } public void showLeftMenu(View view) { getSlidingMenu()showMenu(); } public void showRightMenu(View view) { getSlidingMenu()showSecondaryMenu(); } }
简单说明一下,MainActivity继承的是SlidingFragmentActivity ,在Activity中FragmentPagerAdapter和viewPager作为主布局,然后分别初始化SlidingMenu的两边的菜单。
效果图:
哈哈,微信又躺枪了~~这个例子应该可以满足一般APP的需求了。
5、SlidingMenu的一些常用属性
//设置侧滑菜单的位置,可选值LEFT , RIGHT , LEFT_RIGHT (两边都有菜单时设置) menu.setMode(SlidingMenu.LEFT_RIGHT); // 设置触摸屏幕的模式,可选只MARGIN , CONTENT menu.setTouchModeAbove(SlidingMenu.TOUCHMODE_MARGIN); //根据dimension资源文件的ID来设置阴影的宽度 menu.setShadowWidthRes(R.dimen.shadow_width); //根据资源文件ID来设置滑动菜单的阴影效果 menu.setShadowDrawable(R.drawable.shadow); // 这两个都是设置滑动菜单视图的宽度,二选一 //设置SlidingMenu离屏幕的偏移量 menu.setBehindOffsetRes(R.dimen.slidingmenu_offset); //设置宽度 menu.setBehindWidth() // 设置渐入渐出效果的值 menu.setFadeDegree(0.35f); //设置SlidingMenu与下方视图的移动的速度比,当为1时同时移动,取值0-1 menu.setBehindScrollScale(1.0f); //设置二级菜单的阴影效果 menu.setSecondaryShadowDrawable(R.drawable.shadow); //设置右边(二级)侧滑菜单 menu.setSecondaryMenu(R.layout.right_menu_frame); //为侧滑菜单设置布局 menu.setMenu(R.layout.leftmenu); //把滑动菜单添加进所有的Activity中,可选值SLIDING_CONTENT , SLIDING_WINDOW menu.attachToActivity(this, SlidingMenu.SLIDING_CONTENT);
还有几个监听事件:
/** * 设置打开监听事件,当滑动菜单被打开时调用 */ public void setOnOpenListener(OnOpenListener listener) { mOpenListener = listener; } /** * 设置关闭监听事件,当滑动菜单被关闭时调用 */ public void setOnCloseListener(OnCloseListener listener) { //mViewAbovesetOnCloseListener(listener); mCloseListener = listener; } /** * 设置打开监听事件,当滑动菜单被打开过之后调用 */ public void setOnOpenedListener(OnOpenedListener listener) { mViewAbovesetOnOpenedListener(listener); } /** * 设置关闭监听事件,当滑动菜单被关闭过之后调用 */ public void setOnClosedListener(OnClosedListener listener) { mViewAbovesetOnClosedListener(listener); }
还有一些用到的时候查查把~
我把上面的所有例子包括slidingmenu的lib打了一个包~:demo
