MapApi.jar，点击OK，这样就可以将高德地图Android API 库文件引入。然后在工程Build Path>Configure Build
Path…>Order and Export 中将引入的库文件MapApi.jar 选中，点击OK，这样您就可以在您的程序中使用高德地图API
了。
二、我们在不熟悉的情况下、先尽量多的添加此软件应用权限；所以在mainifest中添加如下代码；插入的位置在
Java代码
三、接着就要在res文件下的layout中添加界面布局了。其代码如下、你可以完全复制进去。
Java代码
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
android:layout_width="wrap_content" android:orientation="horizontal"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_gravity="center_horizontal">
android:text="经度"/>
android:id="@+id/longitude"/>
android:text="纬度"/>
android:id="@+id/latitude"/>
android:clickable="true"
/>
四、最后就是软件的主程序部分了、里面需要的类和方法不多，主要以按钮的监听器和地图的界面实现为主
Java代码
public void onCreate(Bundle savedInstanceState) {
// this.setMapMode(MAP_MODE_VECTOR);//设置地图为矢量模式
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mMapView = (MapView) findViewById(R.id.mapView);
mMapView.setBuiltInZoomControls(true); // 设置启用内置的缩放控件
mMapController = mMapView.getController(); // 得到mMapView
// 的控制权,可以用它控制和驱动平移和缩放
point = new GeoPoint((int) (39.982378 * 1E6), (int) (116.304923 * 1E6)); // 用给定的经纬度构造一个GeoPoint，单位是微度(度*
// 1E6)
// 按钮添加监听器
button_location = (Button) findViewById(R.id.location);
longitude = (EditText) findViewById(R.id.longitude);
latidute = (EditText) findViewById(R.id.latitude);
locationListener = new OnClickListener() {
public void onClick(View e) {
if (e.equals(button_location)) {
// 得到文本输入框的中经纬 度坐标值
String latStr = longitude.getText().toString();
// 将得到的字符串转成数值
double lat = Integer.parseInt(latStr);
String lngStr = latidute.getText().toString();
double lng = Integer.parseInt(lngStr);
//转成经纬度坐标
lat=lat*1E6;
lng=lng*1E6;
// 用给定的经纬度构造一个GeoPoint，单位是微度(度*1E6)
point = new GeoPoint((int) (lat), (int) (lng));
mMapController.setCenter(point); // 设置地图中心点
mMapController.setZoom(12); // 设置地图zoom 级别
// 添加地图覆盖物
// MyLocationOverlay(this, mMapView);
mylocTest.enableMyLocation(); // 判断是否发现位置提供者
mylocTest.enableCompass(); // 打开指南针
mMapView.getOverlays().add(mylocTest);// 添加定位覆盖物
}
}
};
// 按钮添加监听器
button_location.setOnClickListener(locationListener);
mMapController.setCenter(point); // 设置地图中心点
mMapController.setZoom(12); // 设置地图zoom 级别
// 添加地图覆盖物
mylocTest = new MyLocationOverlay(this, mMapView);
mylocTest.enableMyLocation(); // 判断是否发现位置提供者
mylocTest.enableCompass(); // 打开指南针
mMapView.getOverlays().add(mylocTest);// 添加定位覆盖物
}
//另外一个添加界面覆盖物的类：
public class MyLocationOverlayProxy extends com.amap.mapapi.map.MyLocationOverlay{
private Location mLocation;
protected final Paint mPaint = new Paint();
protected final Paint mCirclePaint = new Paint();
private Bitmap gps_marker=null;
private Point mMapCoords = new Point();
private final float gps_marker_CENTER_X;
private final float gps_marker_CENTER_Y;
private final LinkedList
public MyLocationOverlayProxy(amap amap, MapView mMapView) {
super(amap, mMapView);
gps_marker = ((BitmapDrawable) amap.getResources().getDrawable(
R.drawable.marker_gpsvalid)).getBitmap();
gps_marker_CENTER_X = gps_marker.getWidth() / 2 - 0.5f;
gps_marker_CENTER_Y= gps_marker.getHeight() / 2 - 0.5f;
}
public boolean runOnFirstFix(final Runnable runnable) {
if (mLocation != null) {
new Thread(runnable).start();
return true;
} else {
mRunOnFirstFix.addLast(runnable);
return false;
}
}
public void onLocationChanged(Location location) {
// TODO Auto-generated method stub
mLocation = location;
for(final Runnable runnable : mRunOnFirstFix) {
new Thread(runnable).start();
}
mRunOnFirstFix.clear();
super.onLocationChanged(location);
}
protected void drawMyLocation(Canvas canvas, MapView mapView, final Location mLocation,
GeoPoint point, long time) {
Projection pj=mapView.getProjection();
if (mLocation != null) {
mMapCoords=pj.toPixels(point, null);
final float radius = pj.metersToEquatorPixels(mLocation.getAccuracy());
this.mCirclePaint.setAntiAlias(true);
this.mCirclePaint.setARGB(35, 131, 182, 222);
this.mCirclePaint.setAlpha(50);
this.mCirclePaint.setStyle(Style.FILL);
canvas.drawCircle(mMapCoords.x, mMapCoords.y, radius, this.mCirclePaint);
this.mCirclePaint.setARGB(225, 131, 182, 222);
this.mCirclePaint.setAlpha(150);
this.mCirclePaint.setStyle(Style.STROKE);
canvas.drawCircle(mMapCoords.x, mMapCoords.y, radius, this.mCirclePaint);
canvas.drawBitmap(gps_marker, mMapCoords.x-gps_marker_CENTER_X, mMapCoords.y-gps_marker_CENTER_Y, this.mPaint);
}
}
}
