代码启动Google地图，使用Intent显示附近的PizzaHut

 double latitude = gps.getLatitude();
 double longitude = gps.getLongitude();
 String uriBegin = latitude + "," + longitude;
 String uriString = "?q=pizza+hut" + uriBegin + "&z=16";
 Uri uri = Uri.parse(uriString);
 Intent intent = new Intent(android.content.Intent.ACTION_VIEW, uri);
 startActivity(intent);

Answer 1

试试这个网址相应地更改查询和位置参数这里q是指定你的查询ll是你的纬度和经度，z是缩放级别

https://maps.google.com/?q=pizza+hut&ll=-33.867701,151.208471&z=12

在您的应用中添加这段代码

Uri uri = Uri.parse("https://maps.google.com/?q=pizza+hut&ll=-33.867701,151.208471&z=12");
     Intent intent = new Intent(android.content.Intent.ACTION_VIEW, uri);
     intent.setClassName("com.google.android.apps.maps", "com.google.android.maps.MapsActivity");
     startActivity(intent);

Answer 2

使用用户的当前位置显示附近的必胜客餐厅，并启动 Google地图，无需对话。

如果你想摆脱对话框，你可以给意图一个关于你想要使用哪个包的提示。在 startActivity（） 之前添加：

intent.setClassName("com.google.android.apps.maps", "com.google.android.maps.MapsActivity");

最后，您的代码 应该如下所示 ：

double latitude = gps.getLatitude();
double longitude = gps.getLongitude();
String uriBegin = latitude + "," + longitude;
String uriString = "https://maps.google.com/?q=pizza+hut&ll=" + uriBegin + "&z=12";
Uri uri = Uri.parse(uriString);
Intent intent = new Intent(android.content.Intent.ACTION_VIEW, uri);
intent.setClassName("com.google.android.apps.maps",   "com.google.android.maps.MapsActivity");
startActivity(intent);

ActivityNotFound - 使用Intent启动Google Map
