【问题描述】：

朋友们请治愈我.. 我有一个显示谷歌地图的简单应用程序.. 当我运行应用程序时，我收到错误“不幸的是应用程序已停止”

log cat 中的错误是：Failed to inflate android.view.inflateException.Binary xml 文件第 2 行：在 android view.LayoutInflater.createViewFromTag(LayoutInflater.java.713) 处错误膨胀类片段

我已经尝试了许多来自 stackoverflow 和许多其他网站的答案。但在所有这些情况下，我都会遇到同样的错误。

我的代码：

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/mapview"
    android:name="com.google.android.gms.maps.SupportMapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

MainActivity.java

package info.androidhive.googlemapsv2;

import android.os.Bundle;
import android.support.v4.app.FragmentActivity;

import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;

public class MainActivity extends FragmentActivity {

    private GoogleMap map;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        map = ((MapFragment) getFragmentManager()
                .findFragmentById(R.id.mapview)).getMap();
    }
}

【问题讨论】：

发布完整的堆栈跟踪。存在相关的嵌套“由”异常。
如果您在 xml 文件中使用SupportMapFragment，那么为什么在您的 java 文件中使用MapFragment？只需将MapFragment 替换为SupportMapFragment。

标签： android android-fragments google-maps-api-2

【解决方案1】：

像这样将你的地图片段放在RelativeLayout或LinearLayout中；

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

    <fragment
        android:id="@+id/mapview"
        android:name="com.google.android.gms.maps.SupportMapFragment"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" />

 </RelativeLayout>

然后改变

map = ((MapFragment) getFragmentManager()
            .findFragmentById(R.id.mapview)).getMap();

有了这个；

setUpMap();

setUpMap() func 定义将是；

private void setUpMap(){
    if (map != null) {
        return;
    }
    map=((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.mapview)).getMap();
    if (map == null) {
        return;
    }
}

编辑

哦，你也想念的家伙

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

在您的清单文件中。检查this link

我已经尝试了这两种方法，我再次得到错误：错误膨胀类片段
清理你的项目然后重新编译。
我已经尝试过很多次了.. 我尝试过多次创建新项目，但我得到了同样的错误
我已经在标签 @batuhanCpan> 之前给出了
兄弟，我没有告诉你你的 api-key。再次仔细检查我的编辑。

【解决方案2】：

清单中缺少元数据..

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

感谢发现那个bug的BatuhanC先生..

【解决方案3】：

试试这个..

改变这个..

map = ((MapFragment) getFragmentManager()
                .findFragmentById(R.id.mapview)).getMap();

到

map = ((SupportMapFragment) getSupportFragmentManager()
                .findFragmentById(R.id.mapview)).getMap();

和SupportMapFragment 来自 google play 服务库

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