【问题描述】：
我在滑动到 fragment_right 然后 返回 到 fragment_middle 时遇到问题。如果我只从 fragment_middle 向 fragment_left 滑动，反之亦然，一切正常。
我将 FragmentActivity 和 ViewPager 与 ViewPagerAdapter 一起使用。 到目前为止，我有三个 Fragment。
fragment_left 片段中间 fragment_right
fragment_left 的 Google 地图视图如下：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/fragment_left"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="@color/color_lime" >
<RelativeLayout
android:id="@+id/map_map"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="3"
android:background="@color/color_red" >
<fragment
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.SupportMapFragment" />
</RelativeLayout>
<RelativeLayout
android:id="@+id/map_chat"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:background="@color/color_white" >
<TextView
android:id="@+id/map_tv_stupid_info"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="16dp"
android:text="fragment left"
android:textSize="18sp" />
</RelativeLayout>
</LinearLayout>
这是我的 FragmentLeft 类：
package com.example.worldfriends;
import android.content.Context;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class FragmentLeft extends Fragment {
public static Fragment newInstance(Context context) {
FragmentLeft fragment = new FragmentLeft();
return fragment;
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
ViewGroup view = (ViewGroup) inflater.inflate(R.layout.fragment_left, null);
return view;
}
}
这是我的 ViewPagerAdapter：
package com.example.worldfriends;
import android.content.Context;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
public class ViewPagerAdapter extends FragmentPagerAdapter {
private Context context;
private static int totalPage=3;
private int currentItem=1;
public ViewPagerAdapter(Context context, FragmentManager fm) {
super(fm);
this.context=context;
}
@Override
public Fragment getItem(int position) {
Fragment fragment = new Fragment();
switch(position){
case 0:
fragment=FragmentLeft.newInstance(context);
break;
case 1:
fragment=FragmentMiddle.newInstance(context);
break;
case 2:
fragment=FragmentRight.newInstance(context);
break;
}
return fragment;
}
@Override
public int getCount() {
return totalPage;
}
public int getCurrentItem() {
return currentItem;
}
}
如您所见，这是非常基本的。最后但并非最不重要的一点是堆栈跟踪！
