所以我正在关注Android的Google maps API v2,尝试在屏幕上获取基本地图。在完成所有步骤后,我得到一个“错误膨胀类片段”其他人遇到了同样的问题,但没有一个解决方案似乎工作。
确切错误:android.view.InflateException: Binary XML file line #10: Error inflating class fragment
的.java:
import android.os.Bundle;
import android.view.Menu;
import android.support.v4.app.FragmentActivity;
public class GoogleMaps extends FragmentActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_google_maps);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.google_maps, menu);
return true;
}
}
的xml:
<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"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".GoogleMaps" >
<fragment
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.SupportMapFragment"
android:name="com.testing.svma.MainActivity"/>
</RelativeLayout>
我认为我已经正确设置了Google Play服务,它要求在第一次导航页面时下载它们。这是我的project.properties:
# Project target.
target=android-17
android.library=false
android.library.reference.1=../../../android-sdks/extras/google/google_play_services/libproject/google-play-services_lib

我尝试过这些线程的解决方案但没有运气:

我也跟着这个教程并得到了同样的错误:

此问题通常源于您的项目缺少android-support
库。发生这种情况是因为旧版本的api片段不存在,因此您需要添加此库以便在旧版Android中添加对片段的支持。
要执行此操作,请右键单击您的项目,然后:
此外,您可以浏览我在您的应用程序中实施Google地图时写的博客文章:

我遇到了同样的问题并且尝试了每个可能的2天,但是我改变了我的布局xml文件,在java代码中我使用了supportmapfragment
还从包浏览器
导入android支持库 <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
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>

我通过在清单中添加这些行来修复此问题。
<meta-data android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version"/>
答案 3 :(得分:0)
按照此link
中的所有步骤操作您错过了参考Google地图 在您的代码中添加此内容
public class GoogleMaps extends FragmentActivity {
private GoogleMap mMap;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_google_maps);
mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map))
.getMap();
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.google_maps, menu);
return true;
}
}
除了添加地图密钥,添加播放服务到项目

我遇到了同样的错误,并设法通过差异stackoverflow答案的多次尝试来解决它:
不确定哪个是帮助解决问题的那个,但我只列出我做过的事情:
在课堂上引用Google地图(Basavaraj Hampali)
private GoogleMap mMap;
mMap = ((SupportMapFragment) this.getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
if (mMap== null) {
Toast.makeText(this,"Map not Available", Toast.LENGTH_LONG).show();
}
扩展android.support.v4.app.FragmentActivity而不只是“FragmentActivity”(ayush1794)
extends android.support.v4.app.FragmentActivity
希望它有所帮助:)
