Android Google地图不显示
问题描述:
我正在android工作。我想在我的活动中显示简单的Google地图。Android Google地图不显示
这是我的main.xml
<?xml version="1.0" encoding="utf-8"?>
<com.google.android.maps.MapView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/mapview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:clickable="true"
android:apiKey="mykey"
/>
这是我的活动: -
package com.quepplin;
import android.app.Activity;
import android.os.Bundle;
import com.google.android.maps.MapView;
public class GooglemapActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
MapView mMapView;
mMapView = (MapView) findViewById(R.id.mapview);
mMapView.setBuiltInZoomControls(true);
}
}
我已经创建了谷歌成功的关键。但是,每当我运行我的应用程序,然后它崩溃。并在logcat中显示以下错误: -
java.lang.RuntimeException: Unable to start activity
android.view.InflateException: Binary XML file line #2: Error inflating class com.google.android.maps.MapView
Caused by: android.view.InflateException: Binary XML file line #2: Error inflating class com.google.android.maps.MapView
at android.view.LayoutInflater.createView(LayoutInflater.java:513)
请帮我解释我做了什么错误。我很新创建谷歌地图。我在等待建议。
预先感谢您。
答
如果我没看错,然后
public class GooglemapActivity extends Activity
应该
public class GooglemapActivity extends MapActivity
,并在您的清单文件..
<uses-library android:name="com.google.android.maps" />
而且你application build platform is Google-api
