Question

我想根据他提交的地址显示用户位置。为此，我使用Geocoder。但我得到了以下错误。

10-17 18:21:02.734 1914-1934/com.example.googlemapdemo E/GMPM: getGoogleAppId failed with status: 10
10-17 18:21:02.735 1914-1934/com.example.googlemapdemo E/GMPM: Uploading is not possible. App measurement disabled

我已按照所有步骤获取谷歌API密钥。这是我的代码

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'

    compile 'com.google.android.gms:play-services:8.1.0'
    compile 'com.android.support:appcompat-v7:23.0.1'
    compile 'com.android.support:design:23.0.1'
}

MainActivity.java

Geocoder geocoder = new Geocoder(getApplicationContext());
String result=null;

try {
    List addressList = geocoder.getFromLocationName(address.getText().toString(),1);

    if(addressList!=null && addressList.size() > 0) {
        Address address = (Address) addressList.get(0);
        LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
        Criteria criteria = new Criteria();
        String provider = locationManager.getBestProvider(criteria,true);

        double lat = address.getLatitude();
        double longti = address.getLongitude();

        Log.e("lat..long","lat...long"+lat+"....."+longti);
        Intent intent = new Intent(MainActivity.this, MapsActivity.class);
        intent.putExtra("Lat",lat);
        intent.putExtra("Long",longti);
        startActivity(intent);
    }
} catch (IOException e) {
    e.printStackTrace();
}

map.xml

<fragment xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:tools="http://schemas.android.com/tools"

      tools:context="com.example.googlemapdemo.MapsActivity"
      android:name="com.google.android.gms.maps.SupportMapFragment"/>

MapActivity

package com.example.googlemapdemo;

import android.support.v4.app.FragmentActivity;
import android.os.Bundle;

import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;

import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {

    private GoogleMap mMap;
    private double lat, longt;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_maps);
        // Obtain the SupportMapFragment and get notified when the map is ready to be used.
        lat = getIntent().getIntExtra("Lat",0);
        longt = getIntent().getIntExtra("Long",0);

        SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
                .findFragmentById(R.id.map);
        mapFragment.getMapAsync(this);
    }

    /**
     * Manipulates the map once available. This callback is triggered when the map is ready to be
     * used. This is where we can add markers or lines, add listeners or move the camera. In this
     * case, we just add a marker near Sydney, Australia. If Google Play services is not installed

     */
    @Override
    public void onMapReady(GoogleMap googleMap) {
        mMap = googleMap;

        // Add a marker in Sydney and move the camera
        LatLng sydney = new LatLng(lat,longt);
        mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));
        mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));
    }
}

我还为清单添加了所有权限和api密钥

Answer 1

您需要在开发人员控制台的密钥下添加软件包名称和SHA证书指纹。你做到了吗？

Answer 2

您需要添加地图密钥才能在您的应用上显示googlemap。我没有在清单文件中看到它，我只看到使用GeoCoder的密钥

添加您的Google地图密钥后尝试一下。示例如下所示

<meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="AIxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" />

Answer 3

试试这个，它可以帮到你：

Geocoder geocoder = new Geocoder(this, Locale.getDefault());
List<Address> addresses = null;
try {
    addresses = geocoder.getFromLocationName("Location String", 1);
} catch (IOException e) {
    e.printStackTrace();
}
Address address = addresses.get(0);
if(addresses.size() > 0) {
    double latitude = addresses.get(0).getLatitude();
    double longitude = addresses.get(0).getLongitude();
    LatLng latLng = new LatLng(latitude, longitude);
    mMap.addMarker(new MarkerOptions().position(latLng));
    mMap.moveCamera(CameraUpdateFactory.newLatLng(latLng));
    mMap.animateCamera(CameraUpdateFactory.zoomTo(10));
}

从地址在地图上显示位置
