binbinyang---高德地图SDK--2.拖动Marker后得到变化的经纬度(最新SDK.2016/11/29)
http://blog.csdn.net/yangbin0513/article/details/53380185
接着昨天写的文章...代码也是同一个项目代码
今天讲的是最近在项目中. 写的一个高德地图+百度地图合成在一个APK里面做的一个经纬度采集器
今天说的是高德地图SDK-------拖动Marker.得到变化的经纬度
先去下载JAR包
这是我加进去的JAR包
关于Maker点(标记点)
1.默认标记点
LatLng latLng = new LatLng(39.906901,116.397972);
final Marker marker = aMap.addMarker(new MarkerOptions().
position(latLng).
title("北京").
snippet("DefaultMarker"));
2.自定义标记点
markerOption = new MarkerOptions();
markerOption.position(Constants.XIAN);
markerOption.title("西安市").snippet("西安市：34.341568, 108.940174");
markerOption.draggable(true);
markerOption.icon(
BitmapDescriptorFactory.fromBitmap(BitmapFactory
.decodeResource(getResources(),
R.drawable.location_marker)));
// 将Marker设置为贴地显示，可以双指下拉看效果
markerOption.setFlat(true);
下面是标记的一些常用属性： 属性列表
| 名称 | 说明 |
|---|---|
| position | 在地图上标记位置的经纬度值。必填参数 |
| title | 点标记的标题 |
| snippet | 点标记的内容 |
| draggable | 点标记是否可拖拽 |
| visible | 点标记是否可见 |
| anchor | 点标记的锚点 |
| alpha | 点的透明度 |
1)、标记点击回调AMap.OnMarkerClickListener，监听标记点击事件，示例代码如下：
OnMarkerClickListener listener = new OnMarkerClickListener() {
@Override
public boolean onMarkerClick(Marker arg0) {
// TODO Auto-generated method stub
return false;
}
};
//绑定标注点击事件
AMap.setOnMarkerClickListener(listener);
2)、标记拖拽回调AMap.OnMarkerDragListener,监听标记拖拽事件，示例代码如下：
OnMarkerDragListener listener = new OnMarkerDragListener() {
@Override
public void onMarkerDragStart(Marker arg0) {
// TODO Auto-generated method stub
}
@Override
public void onMarkerDragEnd(Marker arg0) {
// TODO Auto-generated method stub
}
@Override
public void onMarkerDrag(Marker arg0) {
// TODO Auto-generated method stub
}
};
//绑定标记拖拽事件
AMap.setOnMarkerDragListener(listener);
3)、信息窗点击事件AMap.OnInfoWindowClickListener
OnInfoWindowClickListener listener = new OnInfoWindowClickListener() {
@Override
public void onInfoWindowClick(Marker arg0) {
arg0.setTitle("infowindow clicked");
}
};
//绑定信息窗点击事件
AMap.setOnInfoWindowClickListener(listener);4.绘制信息窗体
/**
* 监听自定义infowindow窗口的infocontents事件回调
*/
@Override
public View getInfoContents(Marker marker) {
if (radioOption.getCheckedRadioButtonId() != R.id.custom_info_contents) {
return null;
}
View infoContent = getLayoutInflater().inflate(
R.layout.custom_info_contents, null);
render(marker, infoContent);
return infoContent;
}
/**
* 监听自定义infowindow窗口的infowindow事件回调
*/
@Override
public View getInfoWindow(Marker marker) {
if (radioOption.getCheckedRadioButtonId() != R.id.custom_info_window) {
return null;
}
View infoWindow = getLayoutInflater().inflate(
R.layout.custom_info_window, null);
render(marker, infoWindow);
return infoWindow;
}
/**
* 自定义infowinfow窗口
*/
public void render(Marker marker, View view) {
if (radioOption.getCheckedRadioButtonId() == R.id.custom_info_contents) {
((ImageView) view.findViewById(R.id.badge))
.setImageResource(R.drawable.badge_sa);
} else if (radioOption.getCheckedRadioButtonId() == R.id.custom_info_window) {
ImageView imageView = (ImageView) view.findViewById(R.id.badge);
imageView.setImageResource(R.drawable.badge_wa);
}
String title = marker.getTitle();
TextView titleUi = ((TextView) view.findViewById(R.id.title));
if (title != null) {
SpannableString titleText = new SpannableString(title);
titleText.setSpan(new ForegroundColorSpan(Color.RED), 0,
titleText.length(), 0);
titleUi.setTextSize(15);
titleUi.setText(titleText);
} else {
titleUi.setText("");
}
String snippet = marker.getSnippet();
TextView snippetUi = ((TextView) view.findViewById(R.id.snippet));
if (snippet != null) {
SpannableString snippetText = new SpannableString(snippet);
snippetText.setSpan(new ForegroundColorSpan(Color.GREEN), 0,
snippetText.length(), 0);
snippetUi.setTextSize(20);
snippetUi.setText(snippetText);
} else {
snippetUi.setText("");
}
}现在说我写的这个, 首先看效果GIF图. 记住是长按然后拖动Marker点

很多人 如果发现定位不了..你要去看看 你加入了 service没
android:name="com.amap.api.location.APSService"/>
