v2教程
v2教程
提问于 2013-04-09 09:02:47
我正在为Google v2编写教程，网址是：https://developers.google.com/maps/documentation/android/start
我只是试图在我的应用程序中显示一张简单的地图，但它不起作用(应用程序没有打开，还有一个消息框，上面有"Test2“应用程序已经停止)。我也不知道为什么。我完全遵循了教程中所说的话。
这是我的密码：
AndroidManifest.xml：
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.test2"
android:versionCode="1"

</activity>
<meta-data

android:value="The key"/>
</application>
</manifest>activity_main.xml：
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:name="com.google.android.gms.maps.MapFragment"/>MainActivity.java：
package com.example.test2;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}提前谢谢你。

我目前看到的唯一问题是这一行：
<uses-library android:name="com.google.android.maps" />这一行属于Google v1，不应该用Google V2编写。
在没有logcat输出的情况下，我们无法帮助您更多。
更新：
如果现在粘贴了正确的清单文件，那么当前的问题是：
1.您正在为min SDK 8开发应用程序，因此必须在Activity的XML布局文件中使用SupportMapFragment而不是MapFragment对象。就像这样：
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:name="com.google.android.gms.maps.SupportMapFragment"/>您可以看看我写的关于如何向应用程序添加Google Map API V2的博客文章：

您忘记了在中提到的更新的google-play-service lib版本
<application
android:name="packagename"
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
