我正在关注Google Maps Android API v2文档,以便在我的应用程序中使用地图。我收到错误“”我已尝试过所有内容,但仍然无法解决问题。
这是我的 MainActivity.java
package com.example.maps;
import android.app.Activity;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.view.Menu;
import android.view.MenuItem;
public class MainActivity extends FragmentActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
这是 xml 布局
<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"
tools:context="${relativePackage}.${activityClass}" >
<TextView
android:id="@+id/header"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/hello_world" />
<fragment
android:id="@+id/map"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="@+id/header"
/>
</RelativeLayout>
这是我在logcat中得到的错误

请帮我解决此错误。
答案 0 :(得分:1)
你应该改变
android:name="com.google.android.gms.maps.MapFragment"
到
android:name="com.google.android.gms.maps.SupportMapFragment"
因为您使用的是FragmentActivity
您还需要添加manifest.xml
<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
