大家好..
我在活动中有 TabLayout 。我在3号标签处添加了谷歌地图。它工作得很好。但是，当我从标签3滑动到1并尝试再次滑动到标签2或3.应用程序崩溃。我需要一些帮助。
这是我的片段代码：
package com.besho.myapplic.Tour_Fold.Tour_Frg;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import com.besho.myapplic.R;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.CameraPosition;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;
/**
* Created by Besho on 3/8/2016.
*/
public class Flow_Gard_Three extends Fragment {
private SupportMapFragment fragment;
private GoogleMap map;
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
FragmentManager fm = getChildFragmentManager();
fragment = (SupportMapFragment) fm.findFragmentById(R.id.flow_gard_map);
if (fragment == null) {
fragment = SupportMapFragment.newInstance();
fm.beginTransaction().replace(R.id.flow_gard_map, fragment).commit();
}
return inflater.inflate(R.layout.flow_gard_three,container,false);
}
@Override
public void onResume() {
super.onResume();
if (map == null) {
map = fragment.getMap();
LatLng flow_gard_mp = new LatLng(25.0599693,55.2423876);
map.addMarker(new MarkerOptions().position(flow_gard_mp).title("حديقة الزهور"));
map.moveCamera(CameraUpdateFactory.newLatLng(flow_gard_mp));
CameraPosition cameraPosition = new CameraPosition.Builder()
.target(flow_gard_mp) // Sets the center of the map to Mountain View
.zoom(17) // Sets the zoom
.bearing(90) // Sets the orientation of the camera to east
.tilt(30) // Sets the tilt of the camera to 30 degrees
.build();
map.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition));
}
}
这是我的错误：

答案 0 :(得分：1)
R.id.flow_gard_map应为FrameLayout。就是这样！
然后在你的活动中 -
SupportMapFragment mapFragment;
if (mapFragment == null) {
mapFragment = SupportMapFragment.newInstance();
mapFragment.getMapAsync(this);
getChildFragmentManager()
.beginTransaction()
.add(R.id.flow_gard_map, mapFragment)
.commit();
}
答案 1 :(得分：0)
您可以使用此代码：
<a href="delete_contact.php?id=<?php echo $id ?>">
Contact verwijderen
</a>
您还应该在SupportMapFragment supportMapFragment =
(SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.map);
而不是onCreateView()
