当我添加地图片段时:
<fragment 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:id="@+id/map"
tools:context=".MainActivity"
android:name="com.google.android.gms.maps.SupportMapFragment"/>
到activity_main.xml我收到了这个错误:
FATAL EXCEPTION: main
Process: com.example.koba.ogloszenia, PID: 3073
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.koba.ogloszenia/com.example.koba.ogloszenia.MainActivity}: android.view.InflateException: Binary XML file line #120: Error inflating class fragment
at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2379)
...
我的 MainActivity.java :
public class MainActivity extends FragmentActivity implements OnMapReadyCallback {
private GoogleMap mMap;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
SupportMapFragment MapFragment = (SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.map);
MapFragment.getMapAsync(this);
}
@Override
public void onMapReady(GoogleMap Map) {
mMap = Map;
LatLng sydney = new LatLng(-34, 151);
mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));
mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));
}
}
我的 AndroidManifest.xml :
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.koba.ogloszenia">
<uses-permission android:name="android.Manifest.permission.ACCESS_FINE_LOCATION" />

<application

android:icon="@mipmap/ic_launcher"

<meta-data

<intent-filter>

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
我已经包含在依赖
中我还在SDK工具中检查了“Google Play服务”。
我也看过类似的帖子,但这并没有解决我的问题。
提前谢谢。

<meta-data>
元素必须位于<application>
的{{1}}元素内,但必须位于AndroidManifest.xml
元素之外。
