您也可以使用这个完整的代码！它适用于我在您的示例图片中看到的内容。
首先，将此添加到 build.gradle
compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.android.support:design:23.1.1'
compile 'com.android.support:support-annotations:23.1.1'
WineListActivity
//imports
import android.os.Bundle;
import android.support.design.widget.TabLayout;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;
import android.support.v7.app.AppCompatActivity;
import java.util.ArrayList;
import java.util.List;
public class WineListActivity extends AppCompatActivity {
ViewPager viewPager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_winelist);
viewPager = (ViewPager) findViewById(R.id.viewpager);
if (viewPager != null) {
setupViewPager(viewPager);
viewPager.setOffscreenPageLimit(3);
}
TabLayout tabLayout = (TabLayout) findViewById(R.id.viewpager);
tabLayout.setupWithViewPager(viewPager);
}
private void setupViewPager(ViewPager viewPager) {
Adapter adapter = new Adapter(getSupportFragmentManager());
adapter.addFragment(new InformationFragment(), "INFORMATION");
adapter.addFragment(new HomeWebsitesFragment(), "LISTVIEW");
adapter.addFragment(new HomeFragment(), "HOME");
viewPager.setAdapter(adapter);
}
static class Adapter extends FragmentPagerAdapter {
private final List<Fragment> mFragments = new ArrayList<>();
private final List<String> mFragmentTitles = new ArrayList<>();
public Adapter(FragmentManager fm) {
super(fm);
}
public void addFragment(Fragment fragment, String title) {
mFragments.add(fragment);
mFragmentTitles.add(title);
}
@Override
public Fragment getItem(int position) {
return mFragments.get(position);
}
@Override
public int getCount() {
return mFragments.size();
}
@Override
public CharSequence getPageTitle(int position) {
return mFragmentTitles.get(position);
}
}
}
Xml 布局，activity_winelist
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v4.view.ViewPager
android:id="@+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#bdc3c7"
app:layout_behavior="@string/appbar_scrolling_view_behavior" />
</LinearLayout>
您的列表片段，ListFragment
public class ListFragment extends Fragment {
public static final String ARG_PAGE = "ARG_PAGE";
private int mPage;
public static ListFragment newInstance(int page) {
Bundle args = new Bundle();
args.putInt(ARG_PAGE, page);
ListFragment fragment = new ListFragment();
fragment.setArguments(args);
return fragment;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ListView listview = (ListView) findViewById(R.id.listview);
String[] values = new String[] { "wine 1", "wine 2", "wine 3",
"wine 4" };
ArrayList<String> list = new ArrayList<String>();
for (int i = 0; i < values.length; ++i) {
list.add(values[i]);
}
MySimpleArrayAdapter adapter = new MySimpleArrayAdapter(this, list);
if(list.size() == 0){
listview.setEmptyView(findViewById(R.id.emptyview));
}
listview.setAdapter(adapter);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_list, container, false);
return view;
}
}
你的列表，list.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:padding="6dip" >
<TextView
android:id="@+id/label"
android:layout_width="fill_parent"
android:layout_height="26dip"
android:ellipsize="marquee"
android:singleLine="true"
android:text="Description"
android:textSize="12sp" />
</RelativeLayout>
您的适配器，MySimpleArrayAdapter
public class MySimpleArrayAdapter extends ArrayAdapter<String> {
private final Context context;
private final List<String> values;
public MySimpleArrayAdapter(Context context, List<String> values) {
super(context, -1, values);
this.context = context;
this.values = values;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView = inflater.inflate(R.layout.list, parent, false);
TextView textView = (TextView) rowView.findViewById(R.id.label);
textView.setText(values.get(position));
return rowView;
}
}
然后你可以添加你的另外两个 Fragment 并用它们做任何你想做的事情。
HomeFragment
public class HomeFragment extends Fragment {
public static final String ARG_PAGE = "ARG_PAGE";
private int mPage;
public static HomeFragment newInstance(int page) {
Bundle args = new Bundle();
args.putInt(ARG_PAGE, page);
HomeFragment fragment = new HomeFragment();
fragment.setArguments(args);
return fragment;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//mPage = getArguments().getInt(ARG_PAGE);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_home, container, false);
return view;
}
}
信息片段
public class InformationFragment extends Fragment {
public static final String ARG_PAGE = "ARG_PAGE";
private int mPage;
public static InformationFragment newInstance(int page) {
Bundle args = new Bundle();
args.putInt(ARG_PAGE, page);
InformationFragment fragment = new InformationFragment();
fragment.setArguments(args);
return fragment;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//mPage = getArguments().getInt(ARG_PAGE);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_information, container, false);
return view;
}
}
