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。

[java] view
plaincopy





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

[java] view
plaincopy





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

[java] view
plaincopy





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

[html] view
plaincopy





<?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

[html] view
plaincopy





<?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>
