Android地图开发中的地理编码与地理反编码

接着可以在主Layout文件中加入对于地图的显示，这里需要加入刚才申请的MapKey，否则地图将无法正常显示。

< ?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="MapKey"

/>

< /RelativeLayout>

< ?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="MapKey"

/>

< /RelativeLayout>

接着在主Activity的JAVA文件进行修改，支持地图显示。

import com.google.android.maps.MapActivity;

import com.google.android.maps.MapView;

import android.os.Bundle;

public class MapsActivity extends MapActivity

{

/** Called when the activity is first created. */

@Override

public void onCreate(Bundle savedInstanceState)

{

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

MapView mapView = (MapView) findViewById(R.id.mapView);

mapView.setBuiltInZoomControls(true);

}

}
