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/rankun1/article/details/51763840
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 plain copy
- 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 plain copy
- 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 plain copy
- 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 plain copy
- <?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 plain copy
- <?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>
