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:layout_height="wrap_content"
