如何放置一个谷歌地图/ code一viewpager内 [英] How to place a google map/code inside a viewpager
本文介绍了如何放置一个谷歌地图/ code一viewpager内的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
就像标题所说，我想打一个 ViewPager 其中包含两个部分：
Like the title says, I want to make a ViewPager which contains two sections:
1- 列表视图（的地方去用PHP / MySQL的/ JSON的名称）
1- a Listview (name of the places to go with PHP / MySQL / JSON)
2和一个的GoogleMap 与标记取决于你选择1点什么
2- and a GoogleMap with Markers depending of what you select in point 1
所以，我有这个code的ListView和第二code与位置按钮的GoogleMap的。我想在ViewPager合并它们，但我不知道如何使这成为可能。看到我的code以下：
So, I have this code for a ListView and a second code for the GoogleMap with a location Button. I want to merge them in a ViewPager but I don't figure out how to make this possible. See my code below:

TextView description = (TextView) v.findViewById(R.id.tvdesc);
title.setText(page_titles[position]);

}
@Override

}
@Override

}
}
有没有合并这些类的任何选项？让每一页的开关和布局充电？我在Android的更新，你可以帮我知道如何做到这一点？
Is there any options to merge these classes? Make a switch for every page and which layout to charge? I'm newer in Android, can you help me to know how do it?
推荐答案
我在低于viewPager有三个不同的片段。下面这个例子是一个dialogFragment但这并不有所作为它可能是一个活动或片段。
I've got three different fragments in a viewPager below. The example below is a dialogFragment but that doesn't make a difference it could be an activity or a fragment.
public class FragmentPagerSupport extends DialogFragment implements
OnPageChangeListener {
static int NUM_ITEMS = 3;
public interface FragmentPageRefresh {
void onRefresh();
}
MyAdapter mAdapter;
ViewPager mPager;
static FragmentPagerSupport newInstance(int startingPage) {
FragmentPagerSupport f = new FragmentPagerSupport();
// Supply num input as an argument.
Bundle args = new Bundle();
args.putInt("startingPage", startingPage);
f.setArguments(args);
return f;
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
int startingPage = 0;
Bundle b = getArguments();
if (b != null) {
startingPage = b.getInt("startingPage");
}
View view = inflater.inflate(R.layout.fragment_pager, container);
mAdapter = new MyAdapter(this.getChildFragmentManager());
mPager = (ViewPager) view.findViewById(R.id.pager);
mPager.setAdapter(mAdapter);
mPager.setCurrentItem(startingPage);
mPager.setOnPageChangeListener(this);
getDialog().setTitle("Best Rides Settings");
return view;
}
public static class MyAdapter extends FragmentStatePagerAdapter {
// private Map<Integer, Fragment> mPageReferenceMap = new
// HashMap<Integer, Fragment>();
public MyAdapter(FragmentManager fm) {
super(fm);
}
@Override
public int getCount() {
return NUM_ITEMS;
}
@Override
public Fragment getItem(int position) {
Fragment ret = null;
switch (position) {
case 0:
ret = SettingMap.newInstance(position);
break;
case 1:
ret = SettingFollow.newInstance(position);
break;
case 2:
ret = SettingRecord.newInstance(position);
break;
}
// mPageReferenceMap.remove(position);
// mPageReferenceMap.put(position, ret);
return ret;
}
@Override
public CharSequence getPageTitle(int position) {
switch (position) {
case 0:
return "Map Type";
case 1:
return "Follow";
case 2:
return "Tracker";
default:
return "unused";
}
}
下面是你如何在片段做了.newInstance。
Here's how you do the ".newInstance" in the fragment.
public class SettingFollow extends Fragment implements
OnCheckedChangeListener,
android.widget.CompoundButton.OnCheckedChangeListener,
OnSeekBarChangeListener {
public static Fragment newInstance(int position) {
SettingFollow f = new SettingFollow();
// Supply num input as an argument.
Bundle args = new Bundle();
args.putInt("num", position);
f.setArguments(args);
return f;
}
...
}
简单的布局

<!-- Top-level content view for the simple fragment sample. -->
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/default_screen_bg"
android:orientation="vertical" >
<android.support.v4.view.ViewPager
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="0px"
android:layout_weight="1" >
<android.support.v4.view.PagerTitleStrip
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="top" />
</android.support.v4.view.ViewPager>
</LinearLayout>
防火此兽像这样。
fire this beast up like this.
FragmentManager fm = getSupportFragmentManager();
FragmentPagerSupport editSettingsDialog = new FragmentPagerSupport();
// MapSettings editSettingsDialog = new MapSettings();
editSettingsDialog.show(fm, "fragment_edit_name");
