关键代码

MainActivity.java

package com.dzt.slidingmenudemo;

import android.app.Fragment;

import android.app.FragmentManager;

import android.app.FragmentTransaction;

import android.os.Bundle;

import android.util.Log;

import com.dzt.slidingmenudemo.fragment.BluetoothFragment;

import com.dzt.slidingmenudemo.fragment.DisplayFragment;

import com.dzt.slidingmenudemo.fragment.HomeFragment;

import com.dzt.slidingmenudemo.fragment.MenuFragment;

import com.dzt.slidingmenudemo.fragment.WifiFragment;

import com.dzt.slidingmenudemo.fragment.MenuFragment.OnMenuListOnItemClickListener;

import com.slidingmenu.lib.SlidingMenu;

import com.slidingmenu.lib.app.SlidingActivity;

public class MainActivity extends SlidingActivity implements

		OnMenuListOnItemClickListener {

	private SlidingMenu mChannelMenu;

	@Override

	public void onCreate(Bundle savedInstanceState) {

		// TODO Auto-generated method stub

		super.onCreate(savedInstanceState);

		// 设置标题栏的标题

		setTitle("測试SlidingMenu");

	}

	private void initChannelMenu() {

		// 设置側滑栏菜单位置，这里在左边。拉动菜单时。会从左边弹出

		mChannelMenu.setMode(SlidingMenu.LEFT);

		// 设置触摸的范围，这里设置全屏

		mChannelMenu.setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN);

		// 设置阴影的宽度，查看上面第二张效果图，靠右边的位置，有一个阴影过渡。就是这个东西

		mChannelMenu.setShadowWidthRes(R.dimen.shadow_width);

		// 这里是阴影效果，能够设置图片或者一个颜色过渡

		mChannelMenu.setShadowDrawable(R.drawable.shadow);

		// 设置后面间距，側滑栏和原来界面间距

		mChannelMenu.setBehindOffsetRes(R.dimen.slidingmenu_offset);

		// 边框的角度，这里指边界地方

		mChannelMenu.setFadeDegree(0.35f);

		// 设置触摸屏幕的模式

		mChannelMenu.setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN);

		// 设置SlidingMenu的内容

		FragmentTransaction fragmentTransaction = getFragmentManager()

				.beginTransaction();

		MenuFragment menuFragment = new MenuFragment();

		menuFragment.setOnMenuListOnItemClickListener(this);

		fragmentTransaction.replace(R.id.menu_frame, menuFragment);

		fragmentTransaction.replace(R.id.content_frame, new HomeFragment());

		fragmentTransaction.commit();

	}

	@Override

	public void onBackPressed() {

		if (mChannelMenu.isMenuShowing()) {

			// 隐藏SlidingMenu，这里的Content就是我们的主Activity

			mChannelMenu.showContent();

		} else {

			super.onBackPressed();

		}

	}

	@Override

	public void onSelectItem(int position, String title) {

		// TODO Auto-generated method stub

		System.out.println("onSelectItem title = " + title);

		Fragment fragment = null;

		switch (position) {

		case 0:

			fragment = new HomeFragment();

			break;

		case 1:

			fragment = new WifiFragment();

			break;

		case 2:

			fragment = new BluetoothFragment();

			break;

		case 3:

			fragment = new DisplayFragment();

			break;

		default:

			break;

		}

		if (fragment != null) {

			FragmentManager fragmentManager = getFragmentManager();

			fragmentManager.beginTransaction()

					.replace(R.id.content_frame, fragment).commit();

			// update selected item and title, then close the drawer

			setTitle(title);

			mChannelMenu.showContent();

		} else {

			// error in creating fragment

			Log.e("MainActivity", "Error in creating fragment");

		}

	}

}

滑出的Fragment MenuFragment.java

package com.dzt.slidingmenudemo.fragment;

import java.util.ArrayList;

import android.app.Fragment;

import android.os.Bundle;

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup;

import android.widget.AdapterView;

import android.widget.AdapterView.OnItemClickListener;

import android.widget.ListView;

import com.dzt.slidingmenudemo.MenuListAdapter;

import com.dzt.slidingmenudemo.R;

import com.dzt.slidingmenudemo.domain.MenuItem;

public class MenuFragment extends Fragment implements OnItemClickListener {

	private ListView mLv;

	private String[] mMenuTitles;

	private ArrayList<MenuItem> mMenuItem;

	private MenuListAdapter mAdapter;

	private OnMenuListOnItemClickListener mListener;

	public View onCreateView(LayoutInflater inflater, ViewGroup container,

			Bundle savedInstanceState) {

		View rootView = inflater.inflate(R.layout.menu_fragment, container,

				false);

		initWidgets(rootView);

		return rootView;

	}

	private void initWidgets(View rootView) {

		mLv = (ListView) rootView.findViewById(R.id.left_menu);

		mMenuTitles = getResources().getStringArray(R.array.menu_title);

		mMenuItem = new ArrayList<MenuItem>();

		for (int i = 0; i < mMenuTitles.length; i++) {

			MenuItem item = null;

			if (i == 2) {

				item = new MenuItem(mMenuTitles[i], R.drawable.ic_launcher,

						"18", true);

			} else if (i == 4) {

				item = new MenuItem(mMenuTitles[i], R.drawable.ic_launcher,

						"40", true);

			} else {

				item = new MenuItem(mMenuTitles[i], R.drawable.ic_launcher);

			}

			mMenuItem.add(item);

		}

		mAdapter = new MenuListAdapter(getActivity(), mMenuItem);

		mLv.setAdapter(mAdapter);

		mLv.setOnItemClickListener(this);

	}

	@Override

	public void onItemClick(AdapterView<?> parent, View view, int position,

			long id) {

		// TODO Auto-generated method stub

		mLv.setItemChecked(position, true);

		mLv.setSelection(position);

		if (mListener != null) {

			mListener.onSelectItem(position, mMenuTitles[position]);

		}

	}

	public void setOnMenuListOnItemClickListener(

			OnMenuListOnItemClickListener listener) {

		mListener = listener;

	}

	public interface OnMenuListOnItemClickListener {

		public void onSelectItem(int position, String title);

	}

}

点击Menu后。在MainActivity中实现了点击的监听器。就会切换到对应的页面
