尝试在模拟器或设备上运行地图视图时，活动崩溃。我觉得这可能是由于所需库的导入问题。该错误将显示类未找到异常。如果您需要更多信息，请告诉我。我也一直在关注本教程：https ://blog-emildesign.rhcloud.com/?p=435
活动：
package com.klinetel.countydentistfinder;
import com.google.android.gms.maps.*;
import android.app.Activity;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
public class ClinicMapActivity extends FragmentActivity
{
MapView m;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_clinic_map);
}
}
活动布局：
<?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>
显现：
