slidingmenu开源效果

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.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_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>
