首先先上一张开发效果图：
效果是模仿微信的发送位置，项目的框架上采用mvp模式，并用了我自己写的一套lib，地址ndileber
首先界面上的开发，我简单粘贴代码（笑）

</LinearLayout>当然很多资源文件我懒得剔除了，大家自己把资源那块全换为具体数值吧
LocationAdapter的代码，由于我写了两套，一套是百度地图的，一套是高德地图的，里面有切换方式，大家可以吧高德地图的那块去掉。
public class LocationAdapter extends RecyclerView.Adapter<LocationAdapter.LocationViewHolder>{
List<PoiItem> poiItems = null;
List<PoiInfo> poiInfos = null;
LocationAmapActivity.LocationOnCreateItem locationOnCreateItem = null;
LocationBaiduActivity.LocationOnCreateItem locationOnCreateItem2 = null;
public LocationAdapter(List<PoiItem> poiItems,LocationAmapActivity.LocationOnCreateItem locationOnCreateItem){
this.poiItems = poiItems;
this.locationOnCreateItem = locationOnCreateItem;
}
public LocationAdapter(List<PoiInfo> poiInfos, LocationBaiduActivity.LocationOnCreateItem locationOnCreateItem){
this.poiInfos = poiInfos;
this.locationOnCreateItem2 = locationOnCreateItem;
}
public void refData(List<PoiItem> poiItems){
this.poiItems = poiItems;
notifyDataSetChanged();
}
public void refData2(List<PoiInfo> poiInfos){
this.poiInfos = poiInfos;
notifyDataSetChanged();
}
@Override
public LocationViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext())
.inflate(R.layout.recy_location_item, parent, false);
return new LocationViewHolder(view);
}
@Override
public void onBindViewHolder(final LocationViewHolder holder, int position) {
if(App.MAP_TYPE == App.MAP_BAIDU){
holder.poiInfo = poiInfos.get(position);
holder.location_name.setText(holder.poiInfo.name);
holder.location_local.setText(holder.poiInfo.address);
if(locationOnCreateItem2!=null){
holder.mView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
locationOnCreateItem2.onItemClick(holder.poiInfo);
}
});
}
}else{
holder.poiItem = poiItems.get(position);
holder.location_name.setText(holder.poiItem.getTitle());
holder.location_local.setText(holder.poiItem.getSnippet());
Logger.d(holder.poiItem.getCityName()+holder.poiItem.getProvinceName()+holder.poiItem.getSnippet()+holder.poiItem.getWebsite());
if(locationOnCreateItem!=null){
holder.mView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
locationOnCreateItem.onItemClick(holder.poiItem);
}
});
}
}
}
@Override
public int getItemCount() {
if(App.MAP_TYPE == App.MAP_BAIDU){
if(poiInfos==null){
return 0;
}else{
return poiInfos.size();
}
}else{
if(poiItems==null){
return 0;
}else{
return poiItems.size();
}
}
}
public class LocationViewHolder extends RecyclerView.ViewHolder{
private final View mView;
private PoiItem poiItem;
private PoiInfo poiInfo;
private final TextView location_name;
private final TextView location_local;
public LocationViewHolder(View itemView) {
super(itemView);
mView = itemView;
location_name = (TextView) itemView.findViewById(R.id.location_name);
location_local = (TextView) itemView.findViewById(R.id.location_local);
}
}
}
建立接口的连接器：Contract
LocationBaiduContract.java
public interface LocationBaiduContract extends BaseContract{
public interface View extends BaseView<Presenter>{
void setAddress(String address);
void refData(List<PoiInfo> poiInfoList);
void sendButtonStatus(int status);
void pinInfoPanelStatus(int status);
MapView getMapView();
void keybordState(boolean show);
void searchText(String text);
void setPinInfoText(String text);
String getSearchText();
void deleteVisibility(int visiblility);
}
public interface Presenter extends BasePresenter,NimLocationManager.NimLocationListener,
android.view.View.OnClickListener,BaiduMap.OnMapStatusChangeListener,OnGetGeoCoderResultListener,OnGetPoiSearchResultListener,BDLocationListener,LocationBaiduActivity.LocationOnCreateItem,TextWatcher,TextView.OnEditorActionListener {
void initMap();
}
}建立presenter，来操作业务,里面大部分代码都是百度地图开发的代码，基本不解释了
LocationBaiduPresenter.java
public class LocationBaiduPresenter implements LocationBaiduContract.Presenter{
LocationBaiduContract.View view;
public LocationBaiduPresenter(LocationBaiduContract.View view){
this.view = Check.checkNotNull(view, "view cannot be null!");
this.view.setPresenter(this);
}
@Override
public void start() {

@Override

mBaiduMap.setMyLocationEnabled(false);
mSearch.destroy();
}
private double latitude; // 经度
private double longitude; // 维度
private boolean isChick = false;
private String addressInfo; // 对应的地址信息
@Override
public void onGetReverseGeoCodeResult(ReverseGeoCodeResult result) {
if (result == null result.error != SearchResult.ERRORNO.NO_ERROR) {
view.toast( "未找到结果", Toast.LENGTH_LONG);
return;
}

if(!isChick){
view.setAddress(result.getAddress());
latitude = result.getLocation().latitude;
longitude = result.getLocation().longitude;
addressInfo = result.getAddress();
}
isChick = false;
List<PoiInfo> poiInfoList = result.getPoiList();
view.refData(poiInfoList);
return;
}
}
@Override
public void onGetPoiResult(PoiResult result) {
if (result == null result.error == SearchResult.ERRORNO.RESULT_NOT_FOUND) {
view.toast( "未找到结果", Toast.LENGTH_LONG);
return;
}

view.refData(result.getAllPoi());
return;
}
}
