将 SupportMapFragment 放在 DialogFragment 上

Question

我正在尝试在 DialogFragment 上添加 SupportMapFragment，但它返回 error inflating class fragment。我无法弄清楚为什么它返回了error inflating class fragment。我认为我使用的方法是正确的。我需要从 DialogFragment 扩展，因为我想在对话框中显示地图。

我关注了这个answer，也关注了this answer，没有人能解决我的问题。

有人可以帮助我吗？

谢谢。

这是我的 DialogFragment ：

import android.support.v4.app.DialogFragment;

import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.view.LayoutInflater;

/* For widget */
import android.widget.TextView;
import android.widget.ImageView;
import android.widget.Button;

/* Image Downloader Library */
import com.squareup.picasso.Picasso;

/* For string formater */
import com.yai.app.math.support.StringFormater;

/* For object */
import com.yai.app.object.support.Property;
import com.yai.app.object.support.User;

/* For context */
import android.content.Context;

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

/* For map */
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.Marker;
import com.google.android.gms.maps.model.MarkerOptions;

public class DialogFragmentReadAdvertisement extends DialogFragment{
        private Property propertyData;
    private User userData;
    private Context contextData;

    private GoogleMap mapDetail;

    @Override
    public void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);

        propertyData = MainActivity.activeProperty;
        userData = MainActivity.activeUser;
        contextData = App.getContext();
    }

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

        mapDetail = ((SupportMapFragment) getFragmentManager().findFragmentById(R.id.map_data))
                .getMap();

        mapDetail.addMarker(
                new MarkerOptions().position(propertyData.getLocation())
        );

        CameraPosition cameraPosition = new CameraPosition.Builder()
                                            .target(propertyData.getLocation())
                                            .zoom(19)
                                            .tilt(0)
                                            .bearing(0)
                                            .build();

        mapDetail.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition));

        return view;
    }
}

这是我的 xml 布局：

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <!-- One view for ScrollView -->
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

        <!-- Line 13 bellow -->
        <fragment 
          android:id="@+id/map_data"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          class="com.google.android.gms.maps.SupportMapFragment"/>

    </LinearLayout>
</ScrollView>

这是我的 LogCat：

Answer 1

在 DialogFragment 中添加 GoogleMapFragment 时遇到问题，我已将其解决为

@Override
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
    if (Build.VERSION.SDK_INT < 21) {
        supportMapFragment = (SupportMapFragment) getActivity()
                .getSupportFragmentManager().findFragmentById(R.id.mapDialog);
    } else {
        supportMapFragment = (SupportMapFragment) getActivity().getSupportFragmentManager()
                .findFragmentById(R.id.mapDialog);
    }
    supportMapFragment.getMapAsync(this);
}

将 onDestroy() 重写为

 @Override
public void onDestroy() {
    super.onDestroy();
    if (null != supportMapFragment)
        getActivity().getSupportFragmentManager().beginTransaction()
                .remove(supportMapFragment)
                .commit();
}

Answer 2

试试这个..

改变这个..

mapDetail = ((SupportMapFragment) getFragmentManager().findFragmentById(R.id.map_data))
                .getMap();

到

mapDetail = ((SupportMapFragment) getActivity().getSupportFragmentManager().findFragmentById(R.id.map_data))
                .getMap();

Answer 3

如果其他人遇到类似问题...

为了回答您最初的问题，InflateException（错误膨胀类片段）已经发生，因为嵌套片段 - 即您在 DialogFragment 中的 SupportMapFragment - 可能不会从静态 XML 布局中膨胀。

请参阅developer docs 中的此注释：

注意：当布局包含 <fragment> 时，您不能将布局扩展为片段。
只有以编程方式添加到片段时才支持嵌套片段。

因此，您的 layout.xml 应该为 SupportMapFragment 包含一个 <FrameLayout.../>，而不是显式的 <fragment.../>，然后您只需通过代码与布局膨胀添加地图片段。

并且由于 嵌套片段 必须通过来自 getChildFragmentManager() 的 FragmentManager 进行管理， 您需要更改现有的 getFragmentManager() 电话 在设置 FragmentTransaction 以编程方式添加地图片段时（不要忘记提交！）。

作为一个很好的例子，再看看R.layout.mapdialog XML 例子和second SO link 中显示的相关处理 您最初包含在您的问题中。

Answer 4

你的 XML 有问题

<!-- Line 13 bellow -->
        <fragment 
          android:id="@+id/map_data"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          class="com.google.android.gms.maps.SupportMapFragment"/>

使用 android:name 代替类，如下所示

<!-- Line 13 bellow -->
        <fragment 
          android:id="@+id/map_data"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:name="com.google.android.gms.maps.SupportMapFragment"/>
