谷歌地图v2未加载.android.view.InflateException:二进制XML文件行.类片段膨胀错误

Question

这是我的MainActivity。我的应用程序中最小sdk版本是11。我在android manifest文件中使用了API密钥。当我做了一些小的修改，它显示空白的空白，而不是地图。

public class MainActivity extends Activity {
// Google Map
private GoogleMap googleMap;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    try {
        // Loading map
        initilizeMap();
    } catch (Exception e) {
        e.printStackTrace();
    }
}
/**
 * function to load map. If map is not created it will create it for you
 * */
private void initilizeMap() {
    if (googleMap == null) {
        googleMap = ((MapFragment) getFragmentManager().findFragmentById(
                R.id.map)).getMap();
        // check if map is created successfully or not
        if (googleMap == null) {
            Toast.makeText(getApplicationContext(),
                    "Sorry! unable to create maps", Toast.LENGTH_SHORT)
                    .show();
        }
    }
}

}

这是我的布局activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<fragment
    android:id="@+id/map"
    class="com.google.android.gms.maps.MapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:name="com.prasad.maptrial.MainActivity"/>
</RelativeLayout>

这是我的Manifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.prasad.maptrial"
android:versionCode="1"

        </intent-filter>
    </activity>
    <meta-data

</application>
</manifest>

Answer 1

提及这个元数据标签

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

删除打开GLS文件并让我知道结果

Answer 2

试试这个

<fragment
    android:id="@+id/map"
    android:name="com.google.android.gms.maps.SupportMapFragment"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"/>

Answer 3

可以使用

mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.your_id))
            .getMap();

From xml

<fragment
android:id="@+id/your_id"
android:name="com.google.android.gms.maps.SupportMapFragment"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>

在这里添加您的钥匙

 android:value="(MY API KEY)"
