只需按照以下步骤操作，但在此之前请确保您已添加 Google 库和 api key

1.在按钮点击时添加以下功能

private void openAutocompleteActivity() {
        try {
            // The autocomplete activity requires Google Play Services to be available. The intent
            // builder checks this and throws an exception if it is not the case.
            Intent intent = new PlaceAutocomplete.IntentBuilder(PlaceAutocomplete.MODE_OVERLAY)
                    .build(mActivity);
            startActivityForResult(intent, REQUEST_CODE_AUTOCOMPLETE);
        } catch (GooglePlayServicesRepairableException e) {
            // Indicates that Google Play Services is either not installed or not up to date. Prompt
            // the user to correct the issue.
            GoogleApiAvailability.getInstance().getErrorDialog(mActivity, e.getConnectionStatusCode(),
                    0 /* requestCode */).show();
        } catch (GooglePlayServicesNotAvailableException e) {
            // Indicates that Google Play Services is not available and the problem is not easily
            // resolvable.
            String message = "Google Play Services is not available: " +
                    GoogleApiAvailability.getInstance().getErrorString(e.errorCode);

            Log.e("Tag", message);
            Toast.makeText(mActivity, message, Toast.LENGTH_SHORT).show();
        }
    }

2.然后添加这个功能

 @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == REQUEST_CODE_AUTOCOMPLETE) {
            if (resultCode == RESULT_OK) {
                // Get the user's selected place from the Intent.
                Place place = PlaceAutocomplete.getPlace(mActivity, data);
                Log.i("TAG", "Place Selected: " + place.getName());

                LatLng latLng = place.getLatLng();
                latitude = latLng.latitude;
                longitude = latLng.longitude;

                Log.v(ApplicationsConstants.LoginDetails.LATITUDE, "" + latitude);
                Log.v(ApplicationsConstants.LoginDetails.LONGITUDE, "" + longitude);

                tvCity.setText(place.getName());
                Utils.saveDataToPreferences(mActivity, ApplicationsConstants.LoginDetails.CITY, "" + place.getName());
                Utils.saveDataToPreferences(mActivity, ApplicationsConstants.LoginDetails.LATITUDE, "" + latitude);
                Utils.saveDataToPreferences(mActivity, ApplicationsConstants.LoginDetails.LONGITUDE, "" + longitude);

            } else if (resultCode == PlaceAutocomplete.RESULT_ERROR) {
                Status status = PlaceAutocomplete.getStatus(mActivity, data);
                Log.e("TAG", "Error: Status = " + status.toString());
            } else if (resultCode == RESULT_CANCELED) {
                // Indicates that the activity closed before a selection was made. For example if
                // the user pressed the back button.
            }
        }
    }
