求资源到首页上部加群即可。

一. SlidingMenu简介

github:https://github.com/jfeinstein10/SlidingMenu

官网上面的简介上翻译的:

SlidingMenu是能让开发者很容易的开发有滑动菜单App(像Google+,YouTube,Facebook)的开源android库。只要引入这个开源库的许可代码,就可以很容易免费的用在你想要滑动菜单的app。如下图所示:

二.官方小例子

public class SlidingExample extends Activity {    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setTitle(R.string.attach);        // set the content view        setContentView(R.layout.content);        // configure the SlidingMenu        SlidingMenu menu = new SlidingMenu(this);        menu.setMode(SlidingMenu.LEFT);        menu.setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN);        menu.setShadowWidthRes(R.dimen.shadow_width);        menu.setShadowDrawable(R.drawable.shadow);        menu.setBehindOffsetRes(R.dimen.slidingmenu_offset);        menu.setFadeDegree(0.35f);        menu.attachToActivity(this, SlidingMenu.SLIDING_CONTENT);        menu.setMenu(R.layout.menu);    }}

 

自然你也可以用xml定义一个slidingMenu

<com.jeremyfeinstein.slidingmenu.lib.SlidingMenu    xmlns:sliding="http://schemas.android.com/apk/res-auto"    android:id="@+id/slidingmenulayout"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    sliding:viewAbove="@layout/YOUR_ABOVE_VIEW"    sliding:viewBehind="@layout/YOUR_BEHIND_BEHIND"    sliding:touchModeAbove="margin|fullscreen"    sliding:behindOffset="@dimen/YOUR_OFFSET"    sliding:behindWidth="@dimen/YOUR_WIDTH"    sliding:behindScrollScale="@dimen/YOUR_SCALE"    sliding:shadowDrawable="@drawable/YOUR_SHADOW"    sliding:shadowWidth="@dimen/YOUR_SHADOW_WIDTH"    sliding:fadeEnabled="true|false"    sliding:fadeDegree="float"    sliding:selectorEnabled="true|false"    sliding:selectorDrawable="@drawable/YOUR_SELECTOR"/>

 

官方文档翻译如下:

  • viewAbove - 在菜单之上的布局引用
  • viewBehind - 在菜单之下的布局引用
  • touchModeAbove - 指那一部分屏幕触摸后视图显示
  • behindOffset - 菜单显示时,主体显示多少(单位像素)
  • behindWidth - 菜单显示,主体显示的宽。默认全屏
  • behindScrollScale - 菜单显示的滚动设置
  • shadowDrawable - 滚动阴影设置
  • shadowWidth - 滚动阴影的宽度
  • fadeEnabled - 滑动时菜单的是否渐变
  • fadeDegree - 滑动时的渐变程度

 

三.实现滑动菜单

主要结构:MainAct为主入口,然后各个fragment实现各自内容动作。

MainAct.java

public class MainAct extends FragmentActivity {	private SlidingMenu menu;	    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.slidingmenu_main);                menu = new SlidingMenu(this);		menu.setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN);		menu.setShadowWidthRes(R.dimen.slidingmenu_shadow_width);		menu.setShadowDrawable(R.drawable.slidingmenu_shadow);		menu.setBehindOffsetRes(R.dimen.slidingmenu_offset);		DisplayMetrics dm = new DisplayMetrics();		getWindowManager().getDefaultDisplay().getMetrics(dm);		menu.setFadeDegree(0.35f);		menu.setBehindOffset(dm.widthPixels*50/100);		menu.attachToActivity(this, SlidingMenu.SLIDING_CONTENT);						menu.setMode(SlidingMenu.LEFT_RIGHT);//这里模式设置为左右都有菜单,RIGHT显示右菜单,LEFT显示左菜单,LEFT_RIGH显示左右菜单		menu.setContent(R.layout.slidingmenu_content);		menu.setMenu(R.layout.slidingmenu_menu);				menu.setSecondaryMenu(R.layout.slidingmenu_menu_2);		menu.setSecondaryShadowDrawable(R.drawable.slidingmenu_shadow_2);				getSupportFragmentManager()			.beginTransaction()			.replace(R.id.slidingmenu_content, new MainFragment(menu))			.commit();//设置主页面内容				getSupportFragmentManager()			.beginTransaction()			.replace(R.id.slidingmenu_menu, new MainLeftFragment())			.commit();//设置左菜单内容				getSupportFragmentManager()			.beginTransaction()			.replace(R.id.slidingmenu_menu_2, new MainRightFragment(menu))			.commit();//设置右菜单内容           }}

 

总结:用则简单则难
