通过viewPager在活动中添加谷歌地图

我想使用viewPager在活动中显示地图，但我仍然在xml文件中出现渲染问题。

  

片段标记允许布局文件动态包含不同的文件   运行时的布局。在布局编辑时要具体布局   使用不知道。您可以选择所需的布局   编辑布局时预览。     -

     

（选择布局......）

     

请勿在此会话中警告标签

它也在Logcat中创建错误

请告诉我如何解决这个问题。

使用 com.google.android.gms.maps.SupportMapFragment 代替 com.google.android.gms.maps.MapView 

<fragment
        android:id="@+id/map"
        android:name="com.google.android.gms.maps.SupportMapFragment"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_below="@+id/generalId" />

我通过在xml中添加以下代码而不是片段来解决我的问题。

add_masjid.xml 

<com.google.android.gms.maps.MapView
    android:id="@+id/map"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_below="@+id/generalId">

</com.google.android.gms.maps.MapView>

而不是

<fragment
        android:id="@+id/map"
        android:name="com.google.android.gms.maps.SupportMapFragment"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_below="@+id/generalId" />

或java中的这段代码。

package com.example.saroosh.masjidnow.Tabs;

import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

import com.example.saroosh.masjidnow.R;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.MapView;
import com.google.android.gms.maps.MapsInitializer;
import com.google.android.gms.maps.OnMapReadyCallback;
import com.google.android.gms.maps.model.LatLng;

public class AddMasjid extends Fragment implements OnMapReadyCallback{

    MapView gMapView;
    GoogleMap gMap = null;

    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View v =inflater.inflate(R.layout.add_masjid,container,false);

        gMapView = (MapView) v.findViewById(R.id.map);
        gMapView.getMapAsync(this);
        gMapView.onCreate(savedInstanceState);
        gMapView.onResume(); // needed to get the map to display immediately
        try {
            MapsInitializer.initialize(getActivity().getApplicationContext());
        } catch (Exception e) {
            e.printStackTrace();
        }

        return v;
    }

    @Override
    public void onMapReady(GoogleMap map) {
        gMap = map;
        gMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
        gMap.moveCamera(CameraUpdateFactory.newLatLngZoom(new
                LatLng(0,0), 0));
    }
    @Override
    public void onResume() {
        super.onResume();
        gMapView.onResume();
    }

    @Override
    public void onPause() {
        super.onPause();
        gMapView.onPause();
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        gMapView.onDestroy();
    }

    @Override
    public void onLowMemory() {
        super.onLowMemory();
        gMapView.onLowMemory();
    }
