我正在开发一个需要用户位置的应用程序。如果用户关闭位置设置，我无法获取该位置。因此，我按照Android培训提示位置设置对话框让用户转动位置设置： https://developer.android.com/training/location/change-location-settings.html
public static void settingsRequest(final Activity activity) {
LocationRequest mLocationRequest = new LocationRequest();
mLocationRequest.setInterval(10000);
mLocationRequest.setFastestInterval(5000);
mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
.addLocationRequest(mLocationRequest);
builder.setAlwaysShow(true);
SettingsClient client = LocationServices.getSettingsClient(activity);
Task<LocationSettingsResponse> task = client.checkLocationSettings(builder.build());
task.addOnSuccessListener(activity, new OnSuccessListener<LocationSettingsResponse>() {
@Override
public void onSuccess(LocationSettingsResponse locationSettingsResponse) {
// All location settings are satisfied. The client can initialize
// location requests here.
// ...
}
});
task.addOnFailureListener(activity, new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
int statusCode = ((ApiException) e).getStatusCode();
switch (statusCode) {
case CommonStatusCodes.RESOLUTION_REQUIRED:
// Location settings are not satisfied, but this can be fixed
// by showing the user a dialog.
try {
// Show the dialog by calling startResolutionForResult(),
// and check the result in onActivityResult().
ResolvableApiException resolvable = (ResolvableApiException) e;
resolvable.startResolutionForResult(activity,
REQUEST_CHECK_SETTINGS);
} catch (IntentSender.SendIntentException sendEx) {
// Ignore the error.
}
break;
case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
// Location settings are not satisfied. However, we have no way
// to fix the settings so we won't show the dialog.
break;
}
}
});
}
如果位置设置已关闭，则会显示对话框，但问题是当用户触摸对话框外时，对话框将消失。我怎么能防止这种情况？ （像setCanceledOnTouchOutside（false））？
请注意，位置设置对话框不是我的自定义对话框。所以我不能设置setCancelable（false） 该对话框显示何时删除这些代码
// Show the dialog by calling startResolutionForResult(),
// and check the result in onActivityResult().
ResolvableApiException resolvable = (ResolvableApiException) e;
resolvable.startResolutionForResult(activity,
REQUEST_CHECK_SETTINGS);

在AlertDialogue();
.setCancelable(false)
例如;
AlertDialog.Builder alertDialog = new AlertDialog.Builder(mContext);
// Setting Dialog Title
alertDialog.setTitle("GPS is settings");
alertDialog.setCancelable(false);
// Setting Dialog Message
alertDialog.setMessage("GPS is not enabled. Do you want to go to settings menu?");
// On pressing Settings button
alertDialog.setPositiveButton("Settings", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,int which) {
Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
mContext.startActivity(intent);
}
});
// on pressing cancel button
alertDialog.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
});
// Showing Alert Message
alertDialog.show();
