Android开源项目SlidingMenu本学习笔记（两）

我们已经出台SlidingMenu使用：Android开源项目SlidingMenu本学习笔记（一个），接下来再深入学习下。依据滑出项的Menu切换到相应的页面

点击Bluetooth能够切换到对应的界面

import android.util.Log;

		}
	}

	@Override
	public void onSelectItem(int position, String title) {

		System.out.println("onSelectItem title = " + title);
		Fragment fragment = null;
		switch (position) {

		default:
			break;
		}

		if (fragment != null) {

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
