Android ViewPager在多个片段中不显示地图v2

我在fragment inside view pager中显示地图，带有细节片段，用于动态创建片段的地图。我使用单个活动，因此每个屏幕都由一个片段表示。NewsDetails片段包括一个ViewPager（地图）

当我最初导航到NewsDetailsFragment时，地图被加载，现在如果我加载NewsDetailsFragment的一个新实例，就像在滚动页面上一样，我将显示我的下一条记录。第二个NewsDetails片段中的ViewPager不会显示地图。在LogCat中，日志显示一切正常，地图正在显示，标记已设置。但在地图上显示黑屏的地方

如果有1个已加载的地图ViewPager，则任何更多的NewsDetailsFragment都不会显示其地图，只有当我按Back直到没有NewsDetailsFragment（因此没有正在运行的ViewPager）时，只有当我打开NewsDetailsFragment的新实例时，它才会加载地图

请解决我的问题

import com.google.android.gms.maps.SupportMapFragment;

SupportMapFragment mMapFragment = SupportMapFragment.newInstance();     
FragmentManager fm = fragment.getChildFragmentManager();
fm.beginTransaction().add(R.id.map, mMapFragment).commit();
mMapFragment.getMapAsync(this);

@Override
public void onMapReady(GoogleMap googleMap) {
mGoogleMap = googleMap;

if (ActivityCompat.checkSelfPermission(getContext(), Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(getContext(), Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {

mGoogleMap.setMyLocationEnabled(true);

buildGoogleApiClient();

mGoogleApiClient.connect();
}

mGoogleApiClient = new GoogleApiClient.Builder(getContext())
        .addConnectionCallbacks(this)
        .addOnConnectionFailedListener(this)

Location mLastLocation = LocationServices.FusedLocationApi.getLastLocation(
        mGoogleApiClient);
if (mLastLocation != null) {
    //place marker at current position
    mGoogleMap.clear();

mLocationRequest.setPriority(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY);
//mLocationRequest.setSmallestDisplacement(0.1F); //1/10 meter

 LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, this);
}

@Override
public void onConnectionSuspended(int i) {
Toast.makeText(customAdapter.getContext(), "onConnectionSuspended", Toast.LENGTH_SHORT).show();
}

@Override
public void onConnectionFailed(ConnectionResult connectionResult) {
Toast.makeText(customAdapter.getContext(), "onConnectionFailed", Toast.LENGTH_SHORT).show();

}

其中fragment是viewPagerFragment的实例

在xml中

<LinearLayout
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="250dp" />

这是一个已知问题，请查看此链接。我也有同样的问题，看看这个链接。这就解决了问题。假设，我有4个片段。在第2和第3个片段上，我显示地图，在其余两个片段上，我不显示地图。Senerio是：当我将从第1个片段滚动到第2个片段时，在地图的位置上，显示黑屏。然后，我再次从第2个滚动到第1个，从第1个滚动到第2个，地图显示出来。嗨，奥萨伊尔根，我在你提到的链接中看到了解决方案。但对我来说没有用，显示出同样的问题：（FragmentTransaction或view pager中是否有任何设置？

<LinearLayout
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="250dp" />
