使用SupportMapFragment夸大类片段时出错 [英] Error inflating class fragment with SupportMapFragment
本文介绍了使用SupportMapFragment夸大类片段时出错的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
这是另一个使用SupportMapFragment夸大类片段的错误"问题.
Here is yet another "Error inflating class fragment with SupportMapFragment" issue.
这是我的片段XML:
<fragment
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/map"
class="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.myapp.maptest.MapsActivity" />
这是我的活动(它是从主活动中的NavigationDrawer启动的):
Here is my activity (it is started from a NavigationDrawer in the main activity):
public class MapsActivity extends AppCompatActivity implements OnMapReadyCallback, GoogleMap.OnMapLongClickListener {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
}
以下是我的清单的相关部分:
Here are the relevant parts of my Manifest:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_CONTACTS" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<application
android:name="com.myapp.maptest.AppControl"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/MyTheme"
android:allowBackup="false">
<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
<meta-data
android:name="com.google.android.geo.API_KEY"
android:value="XXX"/>
<uses-library android:name="com.google.android.maps" />
很明显，其中有一个实键，而不是XXX
obviously there is a real key in there not XXX
这是来自build.gradle的一些相关代码:
here is some relevant code form the build.gradle:
defaultConfig {
applicationId "com.myapp.maptest"
minSdkVersion 16
targetSdkVersion 23
versionCode 7
versionName "1.5"
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.android.support:support-v4:23.1.1'
compile 'com.android.support:design:23.1.1'
compile 'com.google.android.gms:play-services:7.5.0'
}

问题是，直到昨晚更新Android Studio为止，这一切都工作得很好(即使没有gms.version元数据).起初，我以为只是仿真器图像弄乱了，但是一旦MapActivity尝试对片段进行充气，该应用程序也会在我的手机上崩溃.调试时在setContentView(R.layout.activity_maps)崩溃时说； 我再说一遍，这个确切的代码以前曾经起作用
The thing is, this has worked perfectly fine (even without the gms.version meta-data) until last nights update for Android Studio. At first I thought it was just the emulator image that got messed up, but the app also crashes on my phone as soon as the MapActivity tries to inflate the fragment. Debugging says in crashes at setContentView(R.layout.activity_maps); And I repeat, this exact code has worked before
我试图将活动从AppCompatActivity更改为FragmentActivity，同样的错误.我试图将片段XML放入布局中，同样的错误.以及我在网上找到的几乎所有东西.同样的错误.
I have tried to change the activity from AppCompatActivity to FragmentActivity, same error. I have tried to put the fragment XML into a layout, same error. And pretty much anything I found online. Same error.
非常感谢您的帮助.
