android开发百度地图导航
- 准备工作： 在百度地图上下载依赖，配置key。
- 创建一个demo项目，可显示百度地图的
- 添加按钮，点击按钮，开始导航
- 发起算路我用的是routePlanWithRouteNode这个方法，官网中routePlanWithParams这个方法，我调着闪退，目前不清楚原因
- 这个版本的需要设置隐私政策 SDKInitializer.setAgreePrivacy(this,true);
// 在使用 SDK 各组间之前初始化 context 信息，传入 ApplicationContext
SDKInitializer.setAgreePrivacy(this,true);
// 默认本地个性化地图初始化方法
SDKInitializer.initialize(Utils.getContext());
//自4.3.0起，百度地图SDK所有接口均支持百度坐标和国测局坐标，用此方法设置您使用的坐标类型.
//包括BD09LL和GCJ02两种坐标，默认是BD09LL坐标。
SDKInitializer.setCoordType(CoordType.BD09LL);

- 此时地图会显示比例尺，显示纯绿色 如果用了LocationClient，也给他设置一下
LocationClient.setAgreePrivacy(true);

- 在mainAcitivity中，添加如下代码
private WalkNavigateHelper helper = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
initPermissions(); // 初始化权限
setContentView(R.layout.activity_main); // 填充视图
initView(); // 初始化地图
// 点击按钮开始导航
ImageButton imageButton = findViewById(R.id.nav_btn);
imageButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
// 初始化步行导航
startBikeNavi();
}
});
}
// 初始化权限
private void initPermissions() {
if (Build.VERSION.SDK_INT >= 23) {
ArrayList<String> permissionsList = new ArrayList<>();
String[] permissions = {
Manifest.permission.ACCESS_NETWORK_STATE,
Manifest.permission.INTERNET,
Manifest.permission.ACCESS_COARSE_LOCATION,
Manifest.permission.ACCESS_FINE_LOCATION,
Manifest.permission.WRITE_EXTERNAL_STORAGE,
};
for (String perm : permissions) {
if (PackageManager.PERMISSION_GRANTED != checkSelfPermission(perm)) {
permissionsList.add(perm);
// 进入到这里代表没有权限.
}
if (!permissionsList.isEmpty()) {
String[] strings = new String[permissionsList.size()];
requestPermissions(permissionsList.toArray(strings), 0);
}
}
}
}
