在房子里如何获取Android GPS位置
当一个人呆在房子里时，我需要得到他的gps位置 GPS在室内不工作，但我听到有人解释说，在安卓系统中，你应该首先检查GPS是否可用。如果不是的话，下一步将是根据附近的无线网络定位此人 我对这个很陌生，我计划用钛合金开发一个简单的应用程序。我的问题是:在房子里如何获取Android GPS位置,android,gps,titanium,Android,Gps,Titanium,当一个人呆在房子里时，我需要得到他的gps位置 GPS在室内不工作，但我听到有人解释说，在安卓系统中，你应该首先检查GPS是否可用。如果不是的话，下一步将是根据附近的无线网络定位此人 我对这个很陌生，我计划用钛合金开发一个简单的应用程序。我的问题是: 当gps不可用时，你能基于无线网络定位某人吗？我能知道大楼里人的位置吗 您向位置提供商询问最佳提供商，如果GPS不可用，您将从cellID（移动桅杆）或无线网络获取位置，请参阅和相关stackoverflow您向位置提供商询问最佳提供商，如果GPS
当gps不可用时，你能基于无线网络定位某人吗？我能知道大楼里人的位置吗 您向位置提供商询问最佳提供商，如果GPS不可用，您将从cellID（移动桅杆）或无线网络获取位置，请参阅和相关stackoverflow您向位置提供商询问最佳提供商，如果GPS不可用，您将从cellID（移动桅杆）或无线网络获取位置，请参阅和相关的stackoverflow似乎是一个良好的开端，我希望此代码可以帮助：
try {
gps_enabled = locManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
} catch (Exception ex) {
}
try {
network_enabled = locManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
} catch (Exception ex) {
}
// don't start listeners if no provider is enabled
if (!gps_enabled && !network_enabled) {
AlertDialog.Builder builder = new Builder(this);
builder.setTitle("Attention!");
builder.setMessage("Sorry, location is not determined. Please enable location providers");
builder.create().show();
}
if (gps_enabled) {
locManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locListener);
}
if (network_enabled) {
locManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locListener);
}
从这里开始：似乎是一个好的开始，我希望这段代码可以帮助：
try {
gps_enabled = locManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
} catch (Exception ex) {
}
try {
network_enabled = locManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
} catch (Exception ex) {
}
// don't start listeners if no provider is enabled

if (gps_enabled) {
locManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locListener);
}
if (network_enabled) {
locManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locListener);
}
从这里开始：一个选项是Skyhook。这里是他们SDK的链接。它与android兼容。这不会像GPS那样精确，但它至少会让你在大部分时间内进入正确的建筑物

您可以在任何想要获取cellID位置的地方调用下面的cellID函数。它不会像GPS那样精确
public void cellID()
{
TelephonyManager telephonyManager = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
GsmCellLocation cellLocation = (GsmCellLocation) telephonyManager.getCellLocation();
int cid = cellLocation.getCid();
int lac = cellLocation.getLac();
SimpleDateFormat sdfDateTime = new SimpleDateFormat(
"yyyy-MM-dd HH:mm:ss");
datetimeCellID = sdfDateTime.format(new Date());
String cell_Id=String.valueOf(cid);
String gsm_Loc_Area_Code=String.valueOf(lac);
// Toast.makeText(getBaseContext(),"cellid="+cell_Id+"\nGsm Location Area Code:"+gsm_Loc_Area_Code,Toast.LENGTH_LONG ).show();
if(RqsLocation(cid, lac))
{
TelephonyManager tm = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
imeiCellID = tm.getDeviceId();
latitude_cellID=String.valueOf((float)myLatitude/1000000);
longitude_cellID=String.valueOf((float)myLongitude/1000000);
// Toast.makeText(getBaseContext(),"Lat:"+latitude_cellID+"Long:"+longitude_cellID,Toast.LENGTH_LONG ).show();

这需要多精确？你是否只需要知道某人在哪个街区，或者你需要知道某人在一英尺左右的地方？这需要多准确？你只需要知道某人在哪个街区，还是需要知道某人在一英尺左右的地方？
