我试图在
Android应用程序中显示地图.我正在使用地图V2.但抛出错误“二进制XML文件行#9：错误膨胀类片段”.该应用程序在发布时崩溃.
MainActivity.Java
package com.example.googlemapsv2;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
public class MainActivity extends FragmentActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
activity_main.xml中
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:map="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<fragment
android:name="com.google.android.gms.maps.SupportMapFragment"
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>

解决方法
以下必须是清单文件的内部应用程序标记
参考
<Meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="AIzaSyBAvQK4RAin10dqyflr95tH45Ce_Eko3G0" /> <Meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />
因为你的minsdk是12.你需要使用MapFragment,你的类应该扩展Activity.
<fragment android:name="com.google.android.gms.maps.MapFragment" android:id="@+id/map" android:layout_width="match_parent" android:layout_height="match_parent" />
然后
public class MainActivity extends Activity
确保您正确引用了库项目,并在google api控制台中启用了android的地图.
