这是我用来在我的Android应用程序中编码的程序，用于查找设备的GPS位置。
package com.gps.TestingApps;
import android.app.Activity;
import android.content.Context;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.widget.TextView;
public class TestingApps extends Activity implements LocationListener{
private LocationManager locationManager;
private TextView latitude;
private TextView longitude;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//bind the ui components to code referances
latitude = (TextView) findViewById(R.id.latitude);
longitude = (TextView) findViewById(R.id.longitude);
//get the locationManager
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
startListening();
}
private void startListening() {
//registers our class as the listener
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, (LocationListener) this);
}
private void stopListening() {
locationManager.removeUpdates((LocationListener) this);
}
public void onLocationChanged(Location location) {
latitude.setText(location.getLatitude()+"");
longitude.setText(location.getLongitude()+"");
stopListening();
}
public void onProviderDisabled(String provider) {
// TODO Auto-generated method stub
}
public void onProviderEnabled(String provider) {
// TODO Auto-generated method stub
}
public void onStatusChanged(String provider, int status, Bundle extras) {
// TODO Auto-generated method stub
}
}
我没有得到任何错误，但是存在运行时错误，我无法获得纬度和经度的值，而是获得两者的值false值。
这是我的Logcat中显示的错误消息。

答案 0 :(得分：2)
您的问题与GPS无关。您只是在res / drawable文件夹中缺少一个图标，而您正在某个地方引用该图标，正如您在日志中看到的那样。
