java - 无法启动活动 ComponentInfo 错误

问题描述

在开始时，我的应用程序在开始时正常运行，但在我更新后，当我签入 logcat 时它突然开始崩溃，我收到以下错误 Logcat

从这里我了解到错误在这一行

 super.onCreate(savedInstanceState);
        binding = ActivityDriversMapsBinding.inflate(getLayoutInflater());
        setContentView(binding.getRoot());

但这曾经在一开始就可以工作，现在它无法运行

编辑：这是我的 XML 代码

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".DriversMapsActivity" >
    <fragment
        android:id="@+id/map"
        android:name="com.google.android.gms.maps.SupportMapFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        tools:layout="@layout/activity_customer_maps" />
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/Customerinfo"
        android:layout_gravity="bottom"
        android:orientation="horizontal"
        android:background="@color/white"
        android:visibility="gone"
        >
        <ImageView
            android:layout_width="100sp"
            android:layout_height="100sp"
            android:id="@+id/Profile"
            android:padding="20sp"/>
        <LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:orientation="vertical"
            android:paddingLeft="20sp">
            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:id="@+id/Customername"
                />
            <Button
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:id="@+id/Orderdone"/>
            <Button
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="Call"
                android:id="@+id/Call"
                />
            
        </LinearLayout>

    </LinearLayout>


</FrameLayout>

此外，当我重新编译时它确实可以正常工作，但有时会再次发生这种情况

解决方案

它可能与您SupportMapFragment在 XML 中的片段中初始化您的方式有关（引发膨胀错误的地方）。Google 显示它的方式与您初始化它的方式不同。而不是android:name他们使用class：

<fragment
    class="com.google.android.gms.maps.SupportMapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>
