android– 使用IntentChooser的导航应用程序 – 它是相同的查询？

概述我尝试从我的应用程序调用导航.我打电话给这个查询：Stringlink="geo:"+posInfo.getLatitude()+","+posInfo.getLongitude();IntentnavigateIntent=newIntent(Intent.ACTION_VIEW,Uri.parse(link));Intentchooser=Intent.createChooser(navigateIntent,ctx

我尝试从我的应用程序调用导航.

我打电话给这个查询：

String link = "geo:" + posInfo.getLatitude() + "," + posInfo.getLongitude();Intent navigateIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(link));Intent chooser = Intent.createChooser(navigateIntent, ctx.getString(R.string.navigate_intent_chooser_Title));ctx.startActivity(chooser);

意图选择器显示2个应用程序：GoogleMaps和Waze.

使用Waze的导航工作完美,但使用谷歌地图它不起作用.我显示地图但没有导航说明.
如果我直接使用GoogleMaps,那么我可以导航,这与意图参数的传递方式有关.

我在其他一些答案中读到了我需要对谷歌地图使用另一个查询：

"Google.navigation:q.."

我有两个问题：

>我是否需要针对不同导航应用程序的不同查询？
>如果1为真,我如何使用不同查询的intentChooser？

解决方法:

这是我的解决方案：
 

private static final String PERFIX_DEFAulT_NAVIGATE_link_BY_COORDINATES = "geo:";private static final String PERFIX_DEFAulT_NAVIGATE_link_BY_ADDRESS = "geo:0,0?q=";private static final String PERFIX_DEFAulT_Google_NAVIGATE = "Google.navigation:q=";private static Intent getChooserNavigateIntent(Context context, Intent navigateIntent, POSEntityInfo posInfo, boolean isCoordinates) {    // Check if there is a default app opener for this type of content.    final PackageManager packageManager = context.getPackageManager();    ResolveInfo defaultAppInfo = packageManager.resolveActivity(navigateIntent,            PackageManager.MATCH_DEFAulT_ONLY);    // create the intent for intent chooser    List<Intent> targetedOpenIntents = new ArrayList<Intent>();    List<ResolveInfo> appInfoList = packageManager.queryIntentActivitIEs(navigateIntent,            PackageManager.MATCH_DEFAulT_ONLY);    for (ResolveInfo appInfo : appInfoList) {        String packagename = appInfo.activityInfo.packagename;        Intent targetedOpenIntent = new Intent(androID.content.Intent.ACTION_VIEW).setPackage(packagename);        targetedOpenIntent = getNavigateIntent(appInfo, targetedOpenIntent, isCoordinates, posInfo);        targetedOpenIntents.add(targetedOpenIntent);    }    // create the intent chooser. delete the first member in the List(the default activity)    Intent chooserIntent = Intent.createChooser(targetedOpenIntents.remove(0),            context.getString(R.string.navigate_intent_chooser_Title)).putExtra(Intent.EXTRA_INITIAL_INTENTS,            targetedOpenIntents.toArray(new Parcelable[]{}));    return chooserIntent;}private static Intent getNavigateIntent(ResolveInfo appInfo, Intent navigateIntent, boolean isCoordinates, POSEntityInfo posInfo) {    // link urls    final String Google_NAVIGATE_PACKAGE = "com.Google.androID.apps.maps";    String suffixAddresslink = posInfo.getStreet() + " " + posInfo.getStreetNum() + "," + posInfo.getCity();    String suffixCoordinateslink = posInfo.getLatitude() + "," + posInfo.getLongitude();    boolean isGoogleMaps = Google_NAVIGATE_PACKAGE.equals(appInfo.activityInfo.packagename);    //build the link url    StringBuilder link = new StringBuilder();    link.append(isCoordinates ? (isGoogleMaps ? PERFIX_DEFAulT_Google_NAVIGATE : PERFIX_DEFAulT_NAVIGATE_link_BY_COORDINATES) : (isGoogleMaps ? PERFIX_DEFAulT_Google_NAVIGATE : PERFIX_DEFAulT_NAVIGATE_link_BY_ADDRESS));    link.append(isCoordinates ? suffixCoordinateslink : suffixAddresslink);    Log.d(TAG, "link = " + link);    return navigateIntent.setData(Uri.parse(link.toString()));}

//刚用>关闭标签
