java - Android Google Map API v2 - 膨胀类 fragment 时出错 android.view.InflateException

Question

我按照 Google Maps Android API v2 文档在我的应用程序中使用 map 。我收到错误“”我已经尝试了所有方法，但仍然无法解决它。

这是我的MainActivity.java

package com.example.maps;

import android.app.Activity;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.view.Menu;
import android.view.MenuItem;

public class MainActivity extends FragmentActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    }
}

这是xml布局

<RelativeLayout 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="${relativePackage}.${activityClass}" >

  <TextView
        android:id="@+id/header"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/hello_world" />

 <fragment
          android:id="@+id/map"
          android:name="com.google.android.gms.maps.MapFragment"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:layout_below="@+id/header"
          />

</RelativeLayout>

这是我在 logcat 中遇到的错误

请帮我解决此错误。

Answer 1

你应该改变

  android:name="com.google.android.gms.maps.MapFragment"

至

  android:name="com.google.android.gms.maps.SupportMapFragment"

因为您正在使用FragmentActivity

编辑:

您还需要添加 manifest.xml

 <meta-data
   android:name="com.google.android.gms.version"
   android:value="@integer/google_play_services_version" />
