我正在尝试制作一个使用谷歌地图的应用程序,并且我已经尝试了几乎所有东西,但是我手机上的应用程序现在只显示灰色瓷砖。我确信我的 API 密钥是正确的。
这是我的代码
package net.learn2develop.GoogleMaps;
import com.google.android.gms.maps.MapView;
import com.google.android.maps.GeoPoint;
import com.google.android.maps.MapActivity;
import com.google.android.maps.MapController;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
public class MapsActivity extends MapActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.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;
}
@Override
protected boolean isRouteDisplayed() {
// TODO Auto-generated method stub
return false;
}
}
和xml文件
<?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">
<com.google.android.maps.MapView
android:id="@+id/mapView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:enabled="true"
android:clickable="true"
android:apiKey="AIzaSyBZxTMbzMOaFHau-awITz9CtnxZJkYzryg"
/>
</RelativeLayout>
和 android 清单
<?xml version="1.0" encoding="utf-8"?>
