我正在尝试使用telnet并使用DDMS透视图在我的模拟器上设置GPS位置。似乎没有什么工作,因为如果你认为我的代码屏幕上的输出将是“无法获得GPS位置”。当我在手机上运行时,该应用程序可以正常工作。代码:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
tvLat = (TextView) findViewById(R.id.tvLat);
tvLongi = (TextView) findViewById(R.id.tvLongi);
tvLat.setText("test");
LocationManager lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
Criteria crit = new Criteria();
providers = lm.getBestProvider(crit, false);
Location loc = lm.getLastKnownLocation(providers);
if (loc != null) {
x = loc.getLatitude();
y = loc.getLongitude();
t = "Current latitude: " + x;
t1 = "Current longitude: " + y;
tvLat.setText(t);
tvLongi.setText(t1);
} else {
tvLat.setText("Couldn't get a GPS location");
}
}
@Override
public void onLocationChanged(Location loc) {
// TODO Auto-generated method stub
x = loc.getLatitude();
y = loc.getLongitude();
t = "Current latitude: " + x;
t1 = "Current longitude: " + y;
tvLat.setText(t);
tvLongi.setText(t1);
}
@Override
public void onProviderDisabled(String arg0) {
// TODO Auto-generated method stub
tvLat.setText("GPS disabled");
}
@Override
public void onProviderEnabled(String arg0) {
tvLat.setText("GPS enabled");
}
@Override
public void onStatusChanged(String arg0, int arg1, Bundle arg2) {
}

答案 0 :(得分:3)
来自Eclipse左下角的DDMS Perspective
标签中的Emulator Control
,您有Locations Controls
。从那里你可以输入经度和纬度,然后单击发送将这些坐标发送到选定的模拟器。
也许您仍然无法获取最后知道的位置,但这会触发onLocationChanged()
方法。
编辑:我看到你的班级实现了LocationListener
。您是否使用lm.requestLocationUpdates()
?
EDIT2:我的意思是:
lm.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0,this);
lm.requestLocationUpdates(LocationManager.GPS, 0, 0,this);
