我正在开发一个使用网络位置的应用程序，但我收到了一些用户反馈说他们从未通过此代码块，我假设问题是从未调用位置更改，但它只是发生在几次潜水中，我不能强迫我的失败。
有没有机会解决或控制它？显示无法找到位置的祝酒词，对我有用...
我知道如果用户重新启动手机，该位置将起作用，但这不是用户的解决方案
我把代码放在这里...
final LocationManager lm = (LocationManager) thisOfActivity
.getSystemService(Context.LOCATION_SERVICE);
boolean network_enabled = lm
.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
// SOME STUFF
Location net_loc = lm.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
final LocationListener locationListenerNetwork = new LocationListener() {
public void onLocationChanged(Location location) {
double lat = location.getLatitude();
double lon = location.getLongitude();
Log.e("LATLON", lat + "," + lon);
lm.removeUpdates(this);
// SOME STUFF
myTask task = new myTask();
if (progress.isShowing())
progress.dismiss();
task.execute();
thisOfActivity.registerForContextMenu(tweetList);
}
public void onProviderDisabled(String provider) {
thisOfActivity
.startActivityForResult(
new Intent(
android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS),
0);
if (progress.isShowing())
progress.dismiss();
MainActivity.accionEnCuro = false;
Toast.makeText(
thisOfActivity.getApplicationContext(),
thisOfActivity.getString(R.string.location),
Toast.LENGTH_SHORT).show();
}
public void onProviderEnabled(String provider) {
}
@Override
public void onStatusChanged(String provider,
int status, Bundle extras) {
switch( status ) {
case LocationProvider.AVAILABLE:
Log.e("LocProv", "AVAILABLE");
break;
case LocationProvider.OUT_OF_SERVICE:
Log.e("LocProv", "OUT_OF_SERVICE");
break;
case LocationProvider.TEMPORARILY_UNAVAILABLE:
Log.e("LocProv", "TEMPORARILY_UNAVAILABLE");
break;
}
}
};
if (network_enabled) {
lm.requestLocationUpdates(
LocationManager.NETWORK_PROVIDER, 0, 0,
locationListenerNetwork);
} else {
thisOfActivity
.startActivityForResult(
new Intent(
android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS),
0);
if (progress.isShowing())
progress.dismiss();
MainActivity.accionEnCuro = false;
Toast.makeText(thisOfActivity.getApplicationContext(),
thisOfActivity.getString(R.string.location),
Toast.LENGTH_LONG).show();
}
我已经尝试了下一个想法，我认为它可以工作，至少可以获取位置并且不会让用户等待。
final LocationManager lm = (LocationManager) thisOfActivity
.getSystemService(Context.LOCATION_SERVICE);
boolean network_enabled = lm
.isProviderEnabled(LocationManager.NETWORK_PROVIDER);

LocationListener locationListenerNetwork = null;
// Constructor
class MyThread implements Runnable {
LocationListener locationListenerNetwork;
public MyThread(LocationListener lln) {
locationListenerNetwork = lln;
}
public void run() {
}
}
final Handler myHandler = new Handler();
//Here's a runnable/handler combo
final Runnable MyRunnable = new MyThread(locationListenerNetwork)
{
@Override
public void run() {
if (locationListenerNetwork != null)
lm.removeUpdates(locationListenerNetwork);
Location location = lm.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
if(location != null)
{
double lat = location.getLatitude();
double lon = location.getLongitude();
Log.e("LATLON", lat + "," + lon);
ListView tweetList = (ListView) thisOfActivity
.findViewById(R.id.tweets);
jsonUpdateAsyncTask task = new jsonUpdateAsyncTask(
thisOfActivity, Double.toString(lat),
Double.toString(lon), tweetList);

意见？
