Android Studioによる地図開発（Baidu Map）

プロジェクトは数日中にgithubに送信されますので、参考にしてください

ステップ1. 環境を設定する

1. Baiduマップキーの適用

• まず、以下のサイトにアクセスします。 Baidu Mapsオープンプラットフォーム をクリックし、アカウントにログインして、次の画面に進んでください。
• アプリを作成する」をクリックし、以下の画面に進み、アプリ名を入力し、アプリの種類として「Android SDK」を選択します。
• リリース版のSHA1と開発版のSHA1を取得する、リンクは次の通りです。 Baiduは、SHA1を取得する方法を提供しています。 なお、SHA1はfile.jksをベースに、開発版のSHA1はデバッグ時に使用しdebug.jksをベースに、リリース版はアプリやapkのリリース時に使用し、作成したxxx.jksをベースにします。あなたが唯一のキーを取得するためにSHA1のリリース版を記入した場合、デバッグ時間は、Baiduの地図が表示されていない、覚えている！[OK]をクリックします。

• jarパッケージはlibsディレクトリにインポートされ、ここでは以下のように最もシンプルなBaiduLBS_Android.jarだけがインポートされています。
• mainフォルダの下にjniLibsディレクトリを作成し、以下のようにsoファイルをインポートします。ここで注意するのは、armとx86のディレクトリにあるsoファイルは同じものですが、異なるCPU（arm、x86）用に設定されていることです。armeabiしかない場合、x86仮想マシンではBaiduマップを表示することができません!

ステップ2、基本開発

基本的な機能は、位置情報、緯度・経度・住所を元にした問い合わせなど、簡単な操作です。

• AndroidManifest.xmlファイルに許可証、Baiduキーなどを追加する。

Add menu_item.xml to the menu directory <menu xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" tools:context="com.example.zhangyi.baidumap_test.MainActivity"> <item android:id="@+id/menu_item_mylocation" android:title="My Location" app:showAsAction="never" /> <item android:id="@+id/menu_item_llsearch" android:title="latitude&longitude search" app:showAsAction="never" /> <item android:id="@+id/menu_item_sitesearch" android:title="Address Search" app:showAsAction="never" /> </menu> In MainActivity.java package com.example.wanglei.mymap; import android.content.Context; import android.os.Bundle; import android.support.v7.app.ActionBarActivity; import android.view.Menu; import android.view.MenuItem; import android.view.View; import android.view.inputmethod.InputMethodManager; import android.widget.Button; import android.widget.EditText; import android.widget.LinearLayout; import android.widget.Toast; import com.baidu.location.BDLocation; import com.baidu.location.BDLocationListener; import com.baidu.location.LocationClient; import com.baidu.location.LocationClientOption; import com.baidu.mapapi.SDKInitializer; import com.baidu.mapapi.map; import com.baidu.mapapi.map.BitmapDescriptor; import com.baidu.mapapi.ma private LinearLayout myLinearLayout2; //address search area 2 @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // requestWindowFeature(Window.FEATURE_NO_TITLE); SDKInitializer.initialize(getApplicationContext()); setContentView(R.layout.activity_main); this.context = this; initView(); initLocation(); } private void initView() { myMapView = (MapView) findViewById(R.id.baiduMapView); myBaiduMap = myMapView.getMap(); //scale map level according to the given increment MapStatusUpdate msu= MapStatusUpdateFactory.zoomTo(18.0f); myBaiduMap.setMapStatus(msu); } private void initLocation() { locationMode = MyLocationConfiguration.LocationMode.NORMAL; // Client of the location service.
