Android UI实现SlidingMenu侧滑菜单效果

本篇博客给大家分享一个效果比较好的侧滑菜单的demo，实现点击左边菜单切换fragment。
效果如下：

 

主activity代码：

package com.infzm.slidingmenu.demo; 
 
import android.os.bundle; 
import android.support.v4.app.fragment; 
import android.view.view; 
import android.view.view.onclicklistener; 
import android.view.window; 
import android.widget.imageview; 
import android.widget.textview; 
 
import com.infzm.slidingmenu.demo.fragment.leftfragment; 
import com.infzm.slidingmenu.demo.fragment.todayfragment; 
import com.jeremyfeinstein.slidingmenu.lib.slidingmenu; 
import com.jeremyfeinstein.slidingmenu.lib.app.slidingfragmentactivity; 
 
/**

 */ 
public class mainactivity extends slidingfragmentactivity implements 
    onclicklistener { 
 
  private imageview topbutton; 
  private fragment mcontent; 
  private textview toptextview; 
 
  @override 
  public void oncreate(bundle savedinstancestate) { 
    requestwindowfeature(window.feature_no_title); // 无标题 
    super.oncreate(savedinstancestate); 
    setcontentview(r.layout.activity_main); 
    initslidingmenu(savedinstancestate); 
 
    topbutton = (imageview) findviewbyid(r.id.topbutton); 
    topbutton.setonclicklistener(this); 
    toptextview = (textview) findviewbyid(r.id.toptv); 
  } 
 
  /** 
   * 初始化侧边栏 
   */ 
  private void initslidingmenu(bundle savedinstancestate) { 
    // 如果保存的状态不为空则得到之前保存的fragment，否则实例化myfragment 
    if (savedinstancestate != null) { 
      mcontent = getsupportfragmentmanager().getfragment( 
          savedinstancestate, "mcontent"); 
    } 
 
    if (mcontent == null) { 
      mcontent = new todayfragment(); 
    } 
 
    // 设置左侧滑动菜单 
    setbehindcontentview(r.layout.menu_frame_left); 
    getsupportfragmentmanager().begintransaction() 
        .replace(r.id.menu_frame, new leftfragment()).commit(); 
 
    // 实例化滑动菜单对象 
    slidingmenu sm = getslidingmenu(); 
    // 设置可以左右滑动的菜单 
    sm.setmode(slidingmenu.left); 
    // 设置滑动阴影的宽度 
    sm.setshadowwidthres(r.dimen.shadow_width); 
    // 设置滑动菜单阴影的图像资源 
    sm.setshadowdrawable(null); 
    // 设置滑动菜单视图的宽度 
    sm.setbehindoffsetres(r.dimen.slidingmenu_offset); 
    // 设置渐入渐出效果的值 
    sm.setfadedegree(0.35f); 
    // 设置触摸屏幕的模式,这里设置为全屏 
    sm.settouchmodeabove(slidingmenu.touchmode_fullscreen); 
    // 设置下方视图的在滚动时的缩放比例 
    sm.setbehindscrollscale(0.0f); 
 
  } 
 
  @override 
  protected void onsaveinstancestate(bundle outstate) { 
    super.onsaveinstancestate(outstate); 
    getsupportfragmentmanager().putfragment(outstate, "mcontent", mcontent); 
  } 
 
  /** 
   * 切换fragment 
   * 
   * @param fragment 
   */ 
  public void switchconent(fragment fragment, string title) { 
    mcontent = fragment; 
    getsupportfragmentmanager().begintransaction() 
        .replace(r.id.content_frame, fragment).commit(); 
    getslidingmenu().showcontent(); 
    toptextview.settext(title); 
  } 
 
  @override 
  public void onclick(view v) { 
    switch (v.getid()) { 
    case r.id.topbutton: 
      toggle(); 
      break; 
    default: 
      break; 
    } 
  } 
 
} 

侧边栏菜单fragment

    findviews(view); 
     
    return view; 
  } 
   
   
  public void findviews(view view) { 
    todayview = view.findviewbyid(r.id.tvtoday); 
    lastlistview = view.findviewbyid(r.id.tvlastlist);

    commentsview = view.findviewbyid(r.id.tvmycomments); 
    settingsview = view.findviewbyid(r.id.tvmysettings); 
     
    todayview.setonclicklistener(this); 
    lastlistview.setonclicklistener(this); 
    discussview.setonclicklistener(this); 
    favoritesview.setonclicklistener(this); 
    commentsview.setonclicklistener(this);

  } 
   
  @override

    super.ondestroyview(); 
  } 
   
  @override

    super.ondestroy(); 
  } 
 
  @override 
  public void onclick(view v) { 
    fragment newcontent = null; 
    string title = null; 
    switch (v.getid()) { 
    case r.id.tvtoday: // 今日 
      newcontent = new todayfragment(); 
      title = getstring(r.string.today); 
      break; 
    case r.id.tvlastlist:// 往期列表 
      newcontent = new lastlistfragment();

      newcontent = new discussfragment(); 
      title = getstring(r.string.discussmeetting);

      newcontent = new mysettingsfragment(); 
      title = getstring(r.string.settings); 
      break; 
    default: 
      break; 
    } 
    if (newcontent != null) { 
      switchfragment(newcontent, title); 
    } 
  } 
   
  /** 
   * 切换fragment 
   * @param fragment 
   */ 
  private void switchfragment(fragment fragment, string title) { 
    if (getactivity() == null) { 
      return; 
    } 
    if (getactivity() instanceof mainactivity) { 
      mainactivity fca = (mainactivity) getactivity(); 
      fca.switchconent(fragment, title); 
    } 
  } 
   
}

上面是核心代码，引入slidingmenu开源库。
