【问题描述】：

我试图将我的 GoogleMaps 片段放在 CoordinatorLayout 中，这给了我错误。以前 xml 只是有 GoogleMaps 片段，当时它工作得很好。

activity_bottomsheet_novigo_maps.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_
    android:layout_>

    <fragment
        android:id="@+id/map"
        class="com.google.android.gms.maps.SupportMapFragment"
        android:layout_
        android:layout_ />

</android.support.design.widget.CoordinatorLayout>

bottomsheet_novigo_maps.java

package com.novigo.fiori.trackerapp;

import androidx.annotation.NonNull;
import androidx.appcompat.app.AppCompatActivity;

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

import com.google.android.material.bottomsheet.BottomSheetBehavior;

public class bottomsheet_novigo_maps extends AppCompatActivity implements OnMapReadyCallback 

    private BottomSheetBehavior bottomSheetBehavior;
    private GoogleMap mMap;

    @Override
    protected void onCreate(Bundle savedInstanceState) 
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_bottomsheet_novigo_maps);
        SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
                .findFragmentById(R.id.map);
        mapFragment.getMapAsync(this);
    

    @Override
    public void onMapReady(GoogleMap googleMap) 
        mMap = googleMap;

        // Add a marker in Sydney and move the camera
        LatLng sydney = new LatLng(-34, 151);
        mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));
        mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));

在运行应用程序时，我遇到了上面提到的错误。我有任何其他可能的解决方案来解决这个问题。或者为什么会这样？

【问题讨论】：

与 google MapView 一起使用请检查这个***.com/a/43337454/7846071

@NensiKasundra 嗨，我已经用错误/stack_trace 更新了问题。正如你所说，我已经更改了代码。

XML 中有错误

请检查日志本身是否显示原因：android.view.InflateException：二进制 XML 文件第 2 行：二进制 XML 文件第 2 行：错误膨胀类 android.support.design.widget.CoordinatorLayout 引起: android.view.InflateException: Binary XML file line #2: Error inflating class android.support.design.widget.CoordinatorLayout

而不是这个

【参考方案1】：

我认为您在您的应用程序中使用了 androidx，但您在 CoordinatorLayout 中使用了 android.support.design 版本。所以需要改成androidx版本

从此：

<android.support.design.widget.CoordinatorLayout...

到这里：

<androidx.coordinatorlayout.widget.CoordinatorLayout...
