【问题描述】:
我正在尝试使用 telnet 并使用 DDMS 视角在我的模拟器上设置 GPS 位置。似乎没有任何效果,因为如果您认为我的代码屏幕上的输出将是“无法获得 GPS 位置”。当我在手机上运行该应用程序时,它可以工作。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) {
}
