我正在开发一个获取您当前 GPS 位置的 Android 应用程序,但是当我通过 Eclipse 上的位置控件手动发送纬度和经度值时,toast 不会出现 onLocationChanged。
有什么我遗漏的,因为我已经尝试了所有我能想到的。我将非常感谢您的帮助。
这是我的代码:
package com.currentlocation;
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.Button;
import android.widget.Toast;
public class CurrentLocation extends Activity {
Button button1;
LocationManager mylocationManager;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
button1=(Button)findViewById(R.id.button1);
mylocationManager=(LocationManager)getSystemService(Context.LOCATION_SERVICE);
LocationListener locationlistener=new mylocation();
mylocationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0,locationlistener);
}
public class mylocation implements LocationListener
{
@Override
public void onLocationChanged(Location location) {
String mycurrentLocation="My current location is Latitude"+location.getLatitude()+" and Longitude"+location.getLongitude();
Toast.makeText(getApplicationContext(),mycurrentLocation, Toast.LENGTH_SHORT).show();
}
@Override
public void onProviderDisabled(String provider) {}
@Override
public void onProviderEnabled(String provider) {}
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {}
}
}
这是我的清单代码:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.currentlocation"
android:versionCode="1"
