Question

任何人都可以帮助我 private void isLocationServicesThere() { LocationManager lm = (LocationManager) getActivity().getSystemService(Context.LOCATION_SERVICE); boolean gps_enabled = false; boolean network_enabled = false; try { gps_enabled = lm.isProviderEnabled(LocationManager.GPS_PROVIDER); } catch (Exception ex) { } try { network_enabled = lm.isProviderEnabled(LocationManager.NETWORK_PROVIDER); } catch (Exception ex) { } if (!gps_enabled && !network_enabled) { // notify user AlertDialog.Builder dialog = new AlertDialog.Builder(getActivity()); dialog.setMessage(getActivity().getResources().getString(R.string.gps_network_not_enabled)); dialog.setPositiveButton(getActivity().getResources().getString(R.string.open_location_settings), new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface paramDialogInterface, int paramInt) { // TODO Auto-generated method stub Intent myIntent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS); getActivity().startActivity(myIntent); //get gps } }); dialog.setNegativeButton(getActivity().getString(R.string.Cancel), new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface paramDialogInterface, int paramInt) { // TODO Auto-generated method stub } }); dialog.show(); } } 出场吗？为什么Toast文本浮出其边界？这是我的代码......
