安卓：访问图形页面内片段，ViewPager片段、图形、页面内、ViewPager
我使用的浏览pager来显示三种观点。
I am Using View Pager to Display three Views.
"Filter","Streets","Around"
每个视图是由片段定义。
Each View is Defined by Fragment.
是我想要的： 我想用图形页面里面我FilterFragment。
WHAT I WANT : I want to Use Mapview Inside My FilterFragment.
我做了什么：
我想用图形页面过滤器内片段，但可能无法成功运行。和获取日志美食错误：
I want to Use MapView Inside Filter Fragment but Could Not Able to Run Successfully. and Getting Log cate Error:
android.view.InflateException：二进制XML文件中的行＃33：错误充气类com.google.android.maps.MapView
我还搜查网和＃1这个问题，发现 LINK 和 LINK 却苦于无法找到此链接相关的我的问题，因为我使用片段，ViewPager。
I have also Searched on Net and Stackoverflow about this Problem and Found the LINK and LINK but Could not able to Found this link Related to my Problem as i am using Fragment With ViewPager.
我已经把我的code，如下。
I have put my Code as Below.

TestFragmentAdapter adapter;
ViewPager pager;
@Override

// TODO Auto-generated method stub
super.onCreate(arg0);
Log.i("MainViewPager","Inside Oncreate");
setContentView(R.layout.mainviewpager);
pager = (ViewPager) findViewById(R.id.pager);
adapter = new TestTitleFragmentAdapter(getSupportFragmentManager());
pager.setAdapter(adapter);
TitlePageIndicator indicator = (TitlePageIndicator) findViewById(R.id.indicator);
indicator.setViewPager(pager);
pager.setCurrentItem(1);
}
@Override

"Streets", "Around" };
public String TAG = "TestFragmentAdapter";
private int mCount = CONTENT.length;
public TestFragmentAdapter(FragmentManager fm) {
super(fm);
// TODO Auto-generated constructor stub
}
@Override
public Fragment getItem(int position) {
// TODO Auto-generated method stub
Log.i(TAG, "Inside getItemMethod with position " + position);
if (position == 0) {
Log.i("TestFragmentAdapter","Inside if Condition");
return FilterFragment.newInstance(position);
} else if (position == 1) {
return StreetsFragment.newInstance(position);
} else if (position == 2) {
return AroundFragment.newInstance(position);
} else {
return null;
}
// return MainFragment.newInstance(CONTENT[position % CONTENT.length]);
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return mCount;
}
public void setCount(int count) {
if (count > 0 && count <= 10) {
mCount = count;
notifyDataSetChanged();
}
}
}
下面是我的$ C $下FilterFragment.java：
Here is My Code for FilterFragment.java:
package com.example.viewpageractivitydemo;
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;
public class FilterFragment extends Fragment {
/*

*/
public static Fragment newInstance(int position) {
Log.i("FilterFragment","Inside New Instasnce");
FilterFragment filterFragment = new FilterFragment();
return filterFragment;
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
Log.i("FilterFragment","Inside OcCreateView");
View view = inflater.inflate(R.layout.filter, null);
return view;
}
}
下面是我的$ C $下filter.xml：
Here is My Code for filter.xml:
<?xml version="1.0" encoding="utf-8"?>

请任何人都可以推荐我来回答解决我的问题。我花了在这几个小时。还是没有得到关于我的问题的想法。 Thnks提前。
Please Can anyone Suggest Me Answer to Solve My Problem. I have Spent many Hours on this. Still not getting any Idea about my Question. Thnks in Advance.
推荐答案
您可以使用 LocalActivityManager 来举办一个活动的片段中。这是一个去precated类，但它提供了简单的解决方案。
You can use LocalActivityManager to host a Activity inside a fragment. It is a deprecated class, but it offers the simplest solution.
下面是$ C $下（在code MyFilterFragment ）的片段。 YourMapActivity 是一个扩展 MapActivity 。
Here is the code for a fragment (MyFilterFragment in your code). YourMapActivity is a basic activity that extends MapActivity.
public class MapFragment extends Fragment {
private static final String KEY_STATE_BUNDLE = "localActivityManagerState";
private LocalActivityManager mLocalActivityManager;
protected LocalActivityManager getLocalActivityManager() {
return mLocalActivityManager;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Bundle state = null;
if (savedInstanceState != null) {
state = savedInstanceState.getBundle(KEY_STATE_BUNDLE);
}
mLocalActivityManager = new LocalActivityManager(getActivity(), true);
mLocalActivityManager.dispatchCreate(state);
}
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
//This is where you specify you activity class
Intent i = new Intent(getActivity(), YourMapActivity.class);
Window w = mLocalActivityManager.startActivity("tag", i);
View currentView=w.getDecorView();
currentView.setVisibility(View.VISIBLE);
currentView.setFocusableInTouchMode(true);
((ViewGroup) currentView).setDescendantFocusability(ViewGroup.FOCUS_AFTER_DESCENDANTS);
return currentView;
}
@Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putBundle(KEY_STATE_BUNDLE,
mLocalActivityManager.saveInstanceState());
}
@Override
public void onResume() {
super.onResume();
mLocalActivityManager.dispatchResume();
}
@Override
public void onPause() {
super.onPause();
mLocalActivityManager.dispatchPause(getActivity().isFinishing());
}
@Override
public void onStop() {
super.onStop();
mLocalActivityManager.dispatchStop();
}
@Override
public void onDestroy() {
super.onDestroy();
mLocalActivityManager.dispatchDestroy(getActivity().isFinishing());
}
}
编辑：自从这个答案被张贴，谷歌发布了谷歌地图Android的API与片段支持，正式的 MapFragment 类
Since this answer was posted, Google has released Google Maps Android API with fragment support with an official MapFragment class.
