 使用 keytool(jdk自带工具)获取SHA1

,按照如下步骤进行操作:

1.运行进入控制台。

2.在弹出的控制台窗口中输入 cd .android 定位到 .android 文件夹。

3.继续在控制台输入命令。

debug.keystore:命令为:keytool -list -v -keystore debug.keystore

自定义的 keystore:命令为:keytool -list -v -keystore apk的keystore

如下所示:

提示输入密钥库密码,编译器提供的debug keystore默认密码是 android,自定义签名文件的密码请自行填写。输入密钥后回车(如果没设置密码,可直接回车),此时可在控制台显示的信息中获取 SHA1 值,如下图所示:

说明:keystore 文件为 Android 签名证书文件。

        }




    }

地图上的标记自定义:

 //设置地图标记
    public void addMapMark(int position){
        MarkerOptions markerOption = new MarkerOptions();
        markerOption.position(listData.getLatLng());
        markerOption.title(listData.getName());
        markerOption.draggable(false);
        Bitmap bt = BitmapFactory.decodeFile(listData.getFilePath());
        if(bt != null){
            markerOption.icon(BitmapDescriptorFactory.fromBitmap(BitmapFactory
                    .decodeFile(listData.getFilePath())));
        }else {
            Log.e(TAG, "没有获取到头像,使用默认头像");
            markerOption.icon(BitmapDescriptorFactory.fromBitmap(BitmapFactory
                    .decodeResource(getResources(),R.mipmap.default_avatar1)));
        }

        aMap.addMarker(markerOption);
    }

 

 

根据坐标获得地址:

首先要在class里接口:

public class MainActivity extends BaseActivity implements GeocodeSearch.OnGeocodeSearchListener

然后传入坐标值

    /**
     * 得到地图地址信息
     * @param latLng 坐标值
     */
    public void getAddress(LatLng latLng){
        geocodeSearch = new GeocodeSearch(this);
        geocodeSearch.setOnGeocodeSearchListener(this);
        Log.e(TAG, "getAddress 坐标值:"+"latitude:" +latLng.latitude+"longitude:"+latLng.longitude);
        LatLonPoint latLonPoint = new LatLonPoint(latLng.latitude,latLng.longitude);
        RegeocodeQuery regeocodeQuery = new RegeocodeQuery(latLonPoint,200,GeocodeSearch.AMAP);//发生送坐标、范围、坐标系
        geocodeSearch.getFromLocationAsyn(regeocodeQuery);
    }

 

 

获得坐标的地图地址文本回调

@Override  //根据坐标返回文本地址的回调接口
    public void onRegeocodeSearched(RegeocodeResult regeocodeResult, int i) {
        //1000 是高德官方指定的成功的回返码
        if( i == 1000){
            Log.e(TAG, "onRegeocodeSearched回调码i: "+i );
            RegeocodeAddress regeocodeAddress = regeocodeResult.getRegeocodeAddress();
            address = regeocodeAddress.getFormatAddress();
            Log.e(TAG, "onRegeocodeSearched地址: "+mAddress);
            mAddress.setText(address);
        }else {
            Log.e(TAG, "onRegeocodeSearched回调码i: "+i );
        }

    }

    @Override
    public void onGeocodeSearched(GeocodeResult geocodeResult, int i) {
        //根据地址返回坐标的回调,不用到
    }
