android載入地圖api

㈠ android 百度地圖api定位不準確

不是很了解高德地圖是不是把位置獲取的函數自己封裝起了了哦。
這樣的話，自己提前獲取可能只是做了些無用功而已哦。

不過你還是可以嘗試一下啊。啟動的時候嘗試獲取一下位置就好了。
直接在代碼裡面
new Thead(){
public void run(){
//寫你的獲取位置代碼
}
}.start();
就可以哦。

㈡ 如何使用Android調用百度地圖API

1.先來看看java代碼，MainActivity.class參考代碼如下：
1 public class MainActivity extends MapActivity {
2 // 初始位置設置為西安
3 private double userLongitude = 34.341568 * 1E6;// 緯度
4 private double userLatitude = 108.94017499999995 * 1E6;// 經度
5 // 添加網路相關控制項
6 private MapView mapView;
7 private BMapManager bMapManager;// 載入地圖的引擎
8 // 網路地圖上的key值
9 private String keyString = "";
10 // 在網路地圖上添加一些控制項，例如放大、縮小
11 private MapController mapController;
12 private MKLocationManager mLocationManager;
13
14 @Override
15 public void onCreate(Bundle savedInstanceState) {
16 super.onCreate(savedInstanceState);
17 setContentView(R.layout.activity_main);
18 // 實例化控制項
19 mapView = (MapView) this.findViewById(R.id.bmapView);
20 bMapManager = new BMapManager(MainActivity.this);
21 // 必須要載入key
22 bMapManager.init(keyString, new MKGeneralListener() {
23 // key值不正確
24 @Override
25 public void onGetPermissionState(int arg0) {
26 if (arg0 == 300) {
27 Toast.makeText(MainActivity.this, R.string.key_error,Toast.LENGTH_LONG).show();
28 }
29 }
30 //網路出錯
31 @Override
32 public void onGetNetworkState(int arg0) {
33 Toast.makeText(MainActivity.this, R.string.net_error,Toast.LENGTH_LONG).show();
34 }
35 });
36 this.initMapActivity(bMapManager);
37 mapView.setBuiltInZoomControls(true);// 表示可以設置縮放功能
38 mapController = mapView.getController();
39 // 初始化Location模塊
40 mLocationManager = bMapManager.getLocationManager();
41 // 通過enableProvider和disableProvider方法，選擇定位的Provider
42 mLocationManager.enableProvider(MKLocationManager.MK_NETWORK_PROVIDER);
43 mLocationManager.disableProvider(MKLocationManager.MK_GPS_PROVIDER);
44 //返回手機位置
45 mLocationManager.requestLocationUpdates(locationListener);
46 mLocationManager.setNotifyInternal(5, 2);
47 // 添加定點陣圖層
48 MyLocationOverlay myLocationOverlay = new MyLocationOverlay(this,mapView);
49 myLocationOverlay.enableMyLocation(); // 啟用定位
50 myLocationOverlay.enableCompass(); // 啟用指南針
51 mapView.getOverlays().add(myLocationOverlay);
52 mapView.setTraffic(true);// 交通地圖
53 // mapView.setSatellite(true);// 衛星地圖
54 mapController.setZoom(15);// 設置縮放級別
55 mapView.invalidate();// 刷新地圖
56 }
57 //獲取經度緯度
58 private LocationListener locationListener = new LocationListener() {
59 @Override
60 public void onLocationChanged(Location location) {
61 if (location != null) {
62 userLatitude = location.getLatitude() * 1E6;
63 userLongitude = location.getLongitude() * 1E6;
64 GeoPoint mypoint = new GeoPoint((int)(userLatitude), (int)(userLongitude));
65 mapView.getController().animateTo(mypoint);
66 }
67 }
68 };
69 // 銷毀
70 @Override
71 protected void onDestroy() {
72 super.onDestroy();
73 if (bMapManager != null) {
74 bMapManager.destroy();
75 bMapManager = null;
76 }
77 }
78 // 停止
79 @Override
80 protected void onPause() {
81 super.onPause();
82 if (bMapManager != null) {
83 mLocationManager.removeUpdates(locationListener);
84 bMapManager.stop();
85 }
86 }
87 // 重啟
88 @Override
89 protected void onResume() {
90 super.onResume();
91 if (bMapManager != null) {
92 bMapManager.start();
93 }
94 }
95 //
96 @Override
97 protected boolean isRouteDisplayed() {
98 return false;
99 }
100
101
102 // Menu
103 // 當點擊Menu按鈕時，調用該方法
104 @Override
105 public boolean onCreateOptionsMenu(Menu menu) {
106 menu.add(0, 1, 1, R.string.exit).setIcon(
107 android.R.drawable.ic_menu_close_clear_cancel);
108 return super.onCreateOptionsMenu(menu);
109 }
110 @Override
111 public boolean onContextItemSelected(MenuItem item) { // 選中某個菜單項
112 if (item.getItemId() == 1) {
113 MainActivity.this.finish();
114 }
115 return super.onOptionsItemSelected(item);
116 }
117 // 返回鍵
118 @Override
119 public boolean onKeyDown(int keyCode, KeyEvent event) {
120 if (keyCode == KeyEvent.KEYCODE_BACK) {
121 finish();
122 }
123 return super.onKeyDown(keyCode, event);
124 }
125 }
126
2.布局文件，主要是添加顯示地圖的控制項，activity_mainmain.xml參考代碼如下：
1 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
2 xmlns:tools="http://schemas.android.com/tools"
3 android:layout_width="match_parent"
4 android:layout_height="match_parent" >
5 <!-- 添加顯示網路地圖的控制項 -->
6 <com..mapapi.MapView
7 android:id="@+id/bmapView"
8 android:layout_width="fill_parent"
9 android:layout_height="fill_parent"
10 android:clickable="true"
11 tools:context=".MainActivity" />
12 </LinearLayout>
3.設置配置文件，AndroidManifest.xml參考代碼如下：
1 <manifest xmlns:android="http://schemas.android.com/apk/res/android"
2 package="yu.hong.map"
3 android:versionCode="1"
4 android:versionName="1.0" >
5 <uses-sdk android:minSdkVersion="10" android:targetSdkVersion="15" />
6 <!--添加網路地圖開發授權 -->
7 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
8 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
9 <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
10 <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
11 <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
12 <uses-permission android:name="android.permission.INTERNET" />
13 <uses-permission android:name="android.permission.READ_PHONE_STATE" />
14 <!--添加對屏幕的支持 -->
15 <supports-screens
16 android:anyDensity="true"
17 android:largeScreens="true"
18 android:normalScreens="true"
19 android:resizeable="true"
20 android:smallScreens="true" />
21 <application
22 android:icon="@drawable/ic_maplauncher"
23 android:label="@string/app_name"
24 android:theme="@style/AppTheme" >
25 <activity
26 android:name=".MainActivity"
27 android:label="@string/title_activity_main" >
28 <intent-filter>
29 <action android:name="android.intent.action.MAIN" />
30 <category android:name="android.intent.category.LAUNCHER" />
31 </intent-filter>
32 </activity>
33 </application>
34 </manifest>
