Android SlidingMenu 开源项目使用示例(二)

在上一篇文章中，通过SlidingMenu+Fragment来实现了侧滑菜单，具体连接如下：http://blog.csdn.net/fx_sky/article/details/17354023
本文将更进一步, 在很多实际的应用场景中我们需要一个更复杂的场景，比如说需要在一个菜单选项中集成多个tab来集中显示信息。这个时候 Viewpager就派上用场了。

本例中我们将通过SlidingMenu + ViewPager+Fragment 实现带TAB的SlidingMenu。先看看具体的效果。

实现步骤跟上一篇大体相同，这里着重说需要修改的地方

首先我们需要添加一个PagerAdapter来自动适配Tab里面的Fragment ,就像ListView中的BaseAdapter差不多，只是需要实现的方法有一些区别。

 package com.example.slidingmenuviewpagertest.adapter;

 import java.util.List;

 import com.example.slidingmenuviewpagertest.entity.ContentBean;
 import com.example.slidingmenuviewpagertest.fragment.TestContentFragment;

 import android.support.v4.app.Fragment;
 import android.support.v4.app.FragmentManager;
 import android.support.v4.app.FragmentPagerAdapter;

 public class ContentFragmentPagerAdapter extends FragmentPagerAdapter {

     private List<ContentBean> list;
     public ContentFragmentPagerAdapter(FragmentManager fm) {
         super(fm);
     }

     public ContentFragmentPagerAdapter(FragmentManager fm,List<ContentBean> list) {
         super(fm);
         this.list = list;
     }

     @Override
     public Fragment getItem(int arg0) {

         return TestContentFragment.newInstance(list.get(arg0).getContent());

     }

     @Override
     public int getCount() {
         // TODO Auto-generated method stub
         return list.size();
     }

     @Override
     public CharSequence getPageTitle(int position) {
         // TODO Auto-generated method stub
         return list.get(position).getTitle();
     }

 }

然后在首页Fragment 中初始化ViewPager

 package com.example.slidingmenuviewpagertest.fragment;

 import java.util.ArrayList;
 import java.util.List;

 import android.os.Bundle;
 import android.support.v4.app.Fragment;
 import android.support.v4.view.ViewPager;
 import android.view.LayoutInflater;
 import android.view.View;
 import android.view.ViewGroup;

 import com.example.slidingmenuviewpagertest.R;
 import com.example.slidingmenuviewpagertest.adapter.ContentFragmentPagerAdapter;
 import com.example.slidingmenuviewpagertest.entity.ContentBean;

 public class HomeFragment extends Fragment {

     private ViewPager mViewPager;
     private static final String[] titles = {"One","Two","Three","Four","Five"};
     private List<ContentBean> list = new ArrayList<ContentBean>();
     private ContentFragmentPagerAdapter mAdapter;

     public HomeFragment(){}

     @Override
     public View onCreateView(LayoutInflater inflater, ViewGroup container,
             Bundle savedInstanceState) {

         View rootView = inflater.inflate(R.layout.fragment_home, container, false);

         initData();
         findView(rootView);

         return rootView;
     }

     private void initData() {

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

             ContentBean cb = new ContentBean();
             cb.setTitle(titles[i]);
             cb.setContent(titles[i]+"_"+(i+1));

             list.add(cb);
         }
     }

     private void findView(View rootView) {

         mViewPager = (ViewPager) rootView.findViewById(R.id.mViewPager);
         mAdapter = new ContentFragmentPagerAdapter(getActivity().getSupportFragmentManager(),list);
         mViewPager.setAdapter(mAdapter);
     }

     @Override
     public void onStart() {

         if(mAdapter!=null){
             mAdapter.notifyDataSetChanged();
         }

         super.onStart();
     }
 }

ViewPager中的Fragment

 package com.example.slidingmenuviewpagertest.fragment;

 import android.os.Bundle;
 import android.support.v4.app.Fragment;
 import android.util.Log;
 import android.view.LayoutInflater;
 import android.view.View;
 import android.view.ViewGroup;
 import android.widget.TextView;

 import com.example.slidingmenuviewpagertest.R;

 public class TestContentFragment extends Fragment {
     private static final String TAG = TestContentFragment.class.getSimpleName();
     private String title = "Hello";

     public static TestContentFragment newInstance(String s) {
         TestContentFragment newFragment = new TestContentFragment();
         Bundle bundle = new Bundle();
         bundle.putString("title", s);
         newFragment.setArguments(bundle);

         return newFragment;

     }

     @Override
     public void onCreate(Bundle savedInstanceState) {

         Log.d(TAG, "TestContentFragment-----onCreate");
         Bundle args = getArguments();
         if(args!=null){
             title = args.getString("title");
         }

         super.onCreate(savedInstanceState);
     }

     @Override
     public View onCreateView(LayoutInflater inflater, ViewGroup container,
             Bundle savedInstanceState) {

          View rootView = inflater.inflate(R.layout.fragment_test_content, container, false);

          findView(rootView);

          return rootView;
     }

     private void findView(View rootView) {

         TextView txtLabel = (TextView) rootView.findViewById(R.id.txtLabel);
         txtLabel.setText(title);
     }
 }

TestContentFragment 布局文件 fragment_test_content.xml

 <?xml version="1.0" encoding="utf-8"?>
 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:layout_width="match_parent"
     android:layout_height="match_parent" >

     <TextView
         android:id="@+id/txtLabel"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:layout_centerInParent="true"
         android:text="Pages View"
         android:textSize="16dp" />

     <ImageView
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:layout_below="@id/txtLabel"
         android:layout_centerHorizontal="true"
         android:layout_marginTop="10dp"
         android:src="@drawable/ic_launcher" />

 </RelativeLayout>

首页Fragment 布局文件 fragment_home.xml

 <?xml version="1.0" encoding="utf-8"?>
 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:layout_width="match_parent"
     android:layout_height="match_parent" >

     <android.support.v4.view.ViewPager
         android:id="@+id/mViewPager"
         android:layout_width="match_parent"
         android:layout_height="wrap_content" >

         <android.support.v4.view.PagerTabStrip
             android:id="@+id/pagertab"
             android:layout_width="wrap_content"
             android:layout_height="wrap_content"
             android:layout_gravity="top"/>

 <!--         <android.support.v4.view.PagerTitleStrip
             android:id="@+id/mPagerTitleStrip"
             android:layout_width="match_parent"
             android:layout_height="wrap_content"
             android:layout_gravity="top" /> -->
     </android.support.v4.view.ViewPager>

 </RelativeLayout>
