Android開源項目SlidingMenu的學習筆記（二）

Android開源項目SlidingMenu的學習筆記（二）

在前面已經介紹了SlidingMenu的用法：Android開源項目SlidingMenu的學習筆記（一），接下來再深入學習下，根據滑出項的Menu切換到對應的頁面

目錄結構：

點擊Bluetooth可以切換到相應的介面

關鍵代碼

MainActivity.java

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 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();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);}@Overridepublic void onItemClick(AdapterView parent, View view, int position,long id) {// TODO Auto-generated method stubmLv.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);}}

點擊Menu後，在MainActivity中實現了點擊的監聽器，就會切換到相應的頁面
