Android的碎片卡主机+ viewpager刷卡？ [英] Android fragment tab host + viewpager swipe?
问题描述
我现在有一个片段选项卡中的主机，通过本教程制作 <一href="http://maxalley.word$p$pss.com/2013/05/18/android-creating-a-tab-layout-with-fragmenttabhost-and-fragments/" rel="nofollow">http://maxalley.word$p$pss.com/2013/05/18/android-creating-a-tab-layout-with-fragmenttabhost-and-fragments/
I currently have a fragment tab host, made by this tutorial http://maxalley.wordpress.com/2013/05/18/android-creating-a-tab-layout-with-fragmenttabhost-and-fragments/
唯一的区别是，我使用的这个片段里。 所以，我有标签的片段，每个标签都有另一个片段。
The only difference is that I'm using this inside a fragment. So I have a fragment with the tabs, each tab has another fragment..
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TabWidget
android:id="@android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom" />
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1" />
</LinearLayout>
该片段类
public class AddServiceFragment extends Fragment {
public AddServiceFragment() {
// Required empty public constructor
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_add_service, container, false);
FragmentTabHost mTabHost = (FragmentTabHost) view.findViewById(android.R.id.tabhost);
mTabHost.setup(getActivity(), getChildFragmentManager(), android.R.id.tabcontent);
String[] tabs = new String[]{"text1", "text2"};
mTabHost.addTab(
mTabHost.newTabSpec("tab1").setIndicator(tabs[0], null),
MedicalHistoryFragment.class, null);
mTabHost.addTab(
mTabHost.newTabSpec("tab2").setIndicator(tabs[1], null),
MedicalHistoryFragment.class, null);
return view;
}
这工作，我可以看到我的标签。 现在我想实现一个viewpager，为了能够向左或向右滑动。
This works, I can see my tabs. Now I want to implement a viewpager, in order to be able to swipe left or right.
我已经从Android开发者页面阅读 http://developer.android.com/training/animation/screen-slide.html
I've read this from the android developer page http://developer.android.com/training/animation/screen-slide.html
但我想不通，我应该在哪里把我的viewpager？ 我希望我的片段是独立我的活动......
But I can't figure out, where should I put my viewpager? I want my fragment to be independent of my activity...
推荐答案
TabHost不提供ViewPager支持。
另外，我建议你不要使用TabHost - 这是老式
。
使用<一个href="http://developer.android.com/reference/android/support/v4/view/PagerTabStrip.html">PagerTabStrip
TabHost doesn't provide ViewPager support.
Also, I suggest you to not use TabHost – this is old style.
Use PagerTabStrip
看这要点。
UPD： 我补充一些code，为的情况下，如果要义被删除;
UPD: I add some code, for case, if this Gist be deleted;
MainActivity.java
MainActivity.java
package ch.pboos.android.sample.viewpager;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
public class MainActivity extends FragmentActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
viewPager.setAdapter(new SampleFragmentPagerAdapter());
}
public class SampleFragmentPagerAdapter extends FragmentPagerAdapter {
final int PAGE_COUNT = 5;
public SampleFragmentPagerAdapter() {
super(getSupportFragmentManager());
}
@Override
public int getCount() {
return PAGE_COUNT;
}
@Override
public Fragment getItem(int position) {
return PageFragment.create(position + 1);
}
}
public static class PageFragment extends Fragment {
public static final String ARG_PAGE = "ARG_PAGE";
private int mPage;
public static PageFragment create(int page) {
Bundle args = new Bundle();
args.putInt(ARG_PAGE, page);
PageFragment fragment = new PageFragment();
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_page, container, false);
TextView textView = (TextView) view;
textView.setText("Fragment #" + mPage);
return view;
}
}
}
activity_main.xml（不PagerTabStrip）
activity_main.xml (without PagerTabStrip)
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</android.support.v4.view.ViewPager>
activity_main_2.xml（与PagerTabStrip）
activity_main_2.xml (with PagerTabStrip)
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/pager"
android:layout_width="match_parent"

<android.support.v4.view.PagerTabStrip

android:layout_height="wrap_content"
android:layout_gravity="top"
android:background="#000"
android:paddingBottom="4dp"
android:paddingTop="4dp"
android:textColor="#fff" />
</android.support.v4.view.ViewPager>
fragment_page.xml
fragment_page.xml
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="match_parent"
android:gravity="center" />
getPageTitle
getPageTitle
public CharSequence getPageTitle(int position) {
return "Page " + (position + 1);
}
UPD 2 随着片段：
public class MainFragment extends Fragment{
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.activity_main_2, container, false);
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
viewPager.setAdapter(new SampleFragmentPagerAdapter());
}
public class SampleFragmentPagerAdapter extends FragmentPagerAdapter {
final int PAGE_COUNT = 5;
public SampleFragmentPagerAdapter() {
super(getSupportFragmentManager());
}
@Override
public int getCount() {
return PAGE_COUNT;
}
@Override
public Fragment getItem(int position) {
return PageFragment.create(position + 1);
}
}
public static class PageFragment extends Fragment {
public static final String ARG_PAGE = "ARG_PAGE";
private int mPage;
public static PageFragment create(int page) {
Bundle args = new Bundle();
args.putInt(ARG_PAGE, page);
PageFragment fragment = new PageFragment();
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_page, container, false);
TextView textView = (TextView) view;
textView.setText("Fragment #" + mPage);
return view;
}
}
}
