前言

現在的app很多都需要接入地圖，不同的app都會定義自己的marker以及InforWindow，本文以高德地圖為例，描述自己自定義InfoWindow之路。

先看看效果圖：

高德地圖的SDK以及接入流程，官方文檔已經寫的很明白了：http://lbs.amap.com/

第一步：自定義InforWindow的布局

android:orientation="horizontal"

android:layout_width="wrap_content"

android:layout_height="127dp"

android:background="#0000"

>

android:layout_width="209dp"

android:layout_height="127dp"

android:orientation="vertical"

android:background="@drawable/inforwindow_bg">

android:id="@+id/agent_name"

android:layout_marginLeft="14dp"

android:layout_marginRight="14dp"

android:layout_marginTop="11dp"

android:layout_width="match_parent"

android:layout_height="20dp"

android:textSize="14sp"

android:textColor="@color/black_text"/>

android:id="@+id/agent_addr"

android:layout_marginLeft="14dp"

android:layout_marginRight="14dp"

android:layout_marginTop="2dp"

android:layout_width="match_parent"

android:layout_height="17dp"

android:singleLine="true"

android:textSize="12sp"

android:textColor="@color/black_text2"/>

android:id="@+id/waitNum"

android:layout_marginLeft="14dp"

android:layout_marginTop="2dp"

android:layout_width="wrap_content"

android:layout_height="17dp"

android:textSize="12sp"

android:textColor="#1DA1F2"/>

android:layout_marginLeft="6dp"

android:layout_marginRight="6dp"

android:layout_width="match_parent"

android:layout_height="1dp"

android:layout_marginTop="9dp"

android:background="#DFDFDF"/>

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:orientation="horizontal">

android:layout_marginTop="9dp"

android:id="@+id/navigation_LL"

android:layout_width="0dp"

android:layout_weight="1"

android:layout_height="wrap_content"

>

android:layout_marginLeft="27dp"

android:layout_width="17dp"

android:layout_height="18dp"

android:scaleType="centerCrop"

android:src="@drawable/inforwindow_navigation"/>

android:layout_marginLeft="10dp"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="@string/infowindow_navigation"

android:textSize="14sp"

android:textColor="@color/black_text"/>

android:layout_width="1dp"

android:layout_height="30dp"

android:layout_marginTop="5dp"

android:layout_marginBottom="13dp"

android:background="#DFDFDF"/>

android:layout_marginTop="9dp"

android:id="@+id/call_LL"

android:layout_width="0dp"

android:layout_weight="1"

android:layout_height="wrap_content"

>

android:layout_marginLeft="23dp"

android:layout_width="19dp"

android:layout_height="18dp"

android:scaleType="centerCrop"

android:src="@drawable/inforwindow_call"/>

android:layout_marginLeft="10dp"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="@string/infowindow_call"

android:textSize="14sp"

android:textColor="@color/black_text"/>

android:layout_width="38dp"

android:layout_height="match_parent" />

第二步、自定義適配器

需要繼承高德地圖的AMap.InfoWindowAdapter

package teprinciple.yang.amapinforwindowdemo.adapter;

import android.content.Context;

import android.support.annotation.NonNull;

import android.view.LayoutInflater;

import android.view.View;

import android.widget.LinearLayout;

import android.widget.TextView;

import com.amap.api.maps2d.AMap;

import com.amap.api.maps2d.model.LatLng;

import com.amap.api.maps2d.model.Marker;

import teprinciple.yang.amapinforwindowdemo.base.BaseApplication;

import teprinciple.yang.amapinforwindowdemo.R;

import teprinciple.yang.amapinforwindowdemo.utils.NavigationUtils;

import teprinciple.yang.amapinforwindowdemo.utils.PhoneCallUtils;

/**

* Created by Teprinciple on 2016/8/23.

* 地圖上自定義的infowindow的適配器

*/

public class InfoWinAdapter implements AMap.InfoWindowAdapter, View.OnClickListener {

private Context mContext = BaseApplication.getIntance().getBaseContext();;

private LatLng latLng;

private LinearLayout call;

private LinearLayout navigation;

private TextView nameTV;

private String agentName;

private TextView addrTV;

private String snippet;

@Override

public View getInfoWindow(Marker marker) {

initData(marker);

View view = initView();

return view;

}

@Override

public View getInfoContents(Marker marker) {

return null;

}

private void initData(Marker marker) {

latLng = marker.getPosition();

snippet = marker.getSnippet();

agentName = marker.getTitle();

}

@NonNull

private View initView() {

View view = LayoutInflater.from(mContext).inflate(R.layout.view_infowindow, null);

navigation = (LinearLayout) view.findViewById(R.id.navigation_LL);

call = (LinearLayout) view.findViewById(R.id.call_LL);

nameTV = (TextView) view.findViewById(R.id.name);

addrTV = (TextView) view.findViewById(R.id.addr);

nameTV.setText(agentName);

addrTV.setText(String.format(mContext.getString(R.string.agent_addr),snippet));

navigation.setOnClickListener(this);

call.setOnClickListener(this);

return view;

}

@Override

public void onClick(View v) {

int id = v.getId();

switch (id){

case R.id.navigation_LL: //點擊導航

NavigationUtils.Navigation(latLng);

break;

case R.id.call_LL: //點擊打電話

PhoneCallUtils.call("028-"); //TODO 處理電話號碼

break;

}

}

}

第三步、調用

package teprinciple.yang.amapinforwindowdemo;

import android.os.Bundle;

import android.util.Log;

import com.amap.api.location.AMapLocation;

import com.amap.api.location.AMapLocationClient;

import com.amap.api.location.AMapLocationClientOption;

import com.amap.api.location.AMapLocationListener;

import com.amap.api.maps2d.AMap;

import com.amap.api.maps2d.CameraUpdateFactory;

import com.amap.api.maps2d.MapView;

import com.amap.api.maps2d.UiSettings;

import com.amap.api.maps2d.model.BitmapDescriptorFactory;

import com.amap.api.maps2d.model.LatLng;

import com.amap.api.maps2d.model.Marker;

import com.amap.api.maps2d.model.MarkerOptions;

import teprinciple.yang.amapinforwindowdemo.adapter.InfoWinAdapter;

import teprinciple.yang.amapinforwindowdemo.base.BaseActivity;

import teprinciple.yang.amapinforwindowdemo.entity.Constant;

import teprinciple.yang.amapinforwindowdemo.utils.CheckPermissionsActivity;

public class MainActivity extends CheckPermissionsActivity implements AMap.OnMapClickListener, AMap.OnMarkerClickListener {

private MapView mapView;

private AMap aMap;

private UiSettings uiSettings;

private InfoWinAdapter adapter;

private Marker oldMarker;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

initView();

//在執行onCreateView時執行mMapView.onCreate(savedInstanceState)，實現地圖生命周期管理

mapView.onCreate(savedInstanceState);

initOperation();

}

private void initView() {

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

}

private void initOperation() {

initMap();

}

/**

* 初始化地圖

*/

private void initMap() {

if (aMap == null) {

aMap = mapView.getMap();

uiSettings = aMap.getUiSettings();

aMap.setOnMapClickListener(this);

}

uiSettings.setZoomControlsEnabled(false); //隱藏縮放控件

//自定義InfoWindow

aMap.setOnMarkerClickListener(this);

adapter = new InfoWinAdapter();

aMap.setInfoWindowAdapter(adapter);

addMarkerToMap(Constant.CHENGDU,"成都","中國四川省成都市");

}

@Override

public void onResume() {

super.onResume();

mapView.onResume(); //管理地圖的生命周期

}

@Override

public void onPause() {

super.onPause();

mapView.onPause(); //管理地圖的生命周期

}

@Override

public void onDestroy() {

super.onDestroy();

mapView.onDestroy(); //管理地圖的生命周期

}

//地圖的點擊事件

@Override

public void onMapClick(LatLng latLng) {

//點擊地圖上沒marker 的地方，隱藏inforwindow

if (oldMarker != null) {

oldMarker.hideInfoWindow();

oldMarker.setIcon(BitmapDescriptorFactory.fromResource(R.drawable.marker_normal));

}

}

//maker的點擊事件

@Override

public boolean onMarkerClick(Marker marker) {

if (oldMarker != null) {

oldMarker.setIcon(BitmapDescriptorFactory.fromResource(R.drawable.marker_normal));

}

oldMarker = marker;

marker.setIcon(BitmapDescriptorFactory.fromResource(R.drawable.marker_selected));

return false; //返回 “false”，除定義的操作之外，默認操作也將會被執行

}

private void addMarkerToMap(LatLng latLng, String title, String snippet) {

aMap.addMarker(new MarkerOptions().anchor(0.5f, 0.5f)

.position(latLng)

.title(title)

.snippet(snippet)

.icon(BitmapDescriptorFactory.fromResource(R.drawable.marker_normal))

);

}

}

特別注意

顯示infowindow必須設置title或者sinnipet，同時設置aMap.setInfoWindowAdapter(this)

后記

項目中還包括以下功能(均已適配6.0)：

1、跳轉到高德地圖進行導航功能

2、定位功能
