來自PlaceAutoCompleteAPI的數據沒有被填充到視圖中

Question

因此，我一直試圖從PlaceAutoComplete Fragment中獲取地點標識並將其傳遞給另一個活動。其他活動應該通過從Places.GeoDataApi.getPlaceById（）方法獲取所有必要的信息來獲取地點id並擴大視圖。

這裏就是PlaceAutoComplete片段存儲類：

public class PlaceSearch extends AppCompatActivity { 
@Override 
protected void onCreate(@Nullable Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_place_search); 

    //Hiding SupportActionBar 
    try { 
     getSupportActionBar().hide(); 
    } catch (Exception e) { 
     e.printStackTrace(); 
    } 

    //PlaceAutoComplete Search Implementation 
    PlaceAutocompleteFragment autocompleteFragment = (PlaceAutocompleteFragment) 
      getFragmentManager().findFragmentById(R.id.place_autocomplete_fragment); 


    autocompleteFragment.setOnPlaceSelectedListener(new PlaceSelectionListener() { 
     @Override 
     public void onPlaceSelected(Place place) { 
      Log.i(String.valueOf(this), "Place: " + place.getName() + "\nID: " + place.getId()); 
      String placeId = place.getId(); 
      try { 
       Intent intent = new Intent(PlaceSearch.this, PlaceDetailsFromSearch.class); 
       Bundle extras = new Bundle(); 
       extras.putString("placeID", placeId); 
       intent.putExtras(extras); 
       startActivity(intent); 
      } catch (Exception e) { 
       e.printStackTrace(); 
      } 
     } 

     @Override 
     public void onError(Status status) { 
      Log.i(String.valueOf(this), "An error occurred: " + status); 
     } 
    }); 
}} 

而這裏就是我試圖誇大數據的類：

public class PlaceDetailsFromSearch extends AppCompatActivity implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener { 

String placeId, placeName, placeAddress, placeContact; 
String placeWeblink; 
float placeRating; 
//Views References 
RatingBar ratingBar; 
TextView tv_place_name, tv_address, tv_call_info, tv_website_info; 
private GoogleApiClient mGoogleApiClient; 

@Override 
protected void onCreate(@Nullable Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_place_details_search); 

    Intent intent = getIntent(); 
    if (intent != null) { 
     Bundle extras = intent.getExtras(); 
     placeId = extras.getString("placeId"); 
    } 

    //views 
    tv_place_name = (TextView) findViewById(R.id.tv_place_name_pd); 
    tv_address = (TextView) findViewById(R.id.tv_address); 
    tv_call_info = (TextView) findViewById(R.id.tv_call_info); 
    tv_website_info = (TextView) findViewById(R.id.tv_website_info); 
    ratingBar = (RatingBar) findViewById(R.id.rb_rating); 

    //Google API Client 
    mGoogleApiClient = new GoogleApiClient.Builder(this) 
      .addApi(Places.GEO_DATA_API) 
      .addConnectionCallbacks(this) 
      .addOnConnectionFailedListener(this).build(); 

    loadData(); 
} 

private void loadData() { 
    Places.GeoDataApi.getPlaceById(mGoogleApiClient, placeId) 
      .setResultCallback(new ResultCallback<PlaceBuffer>() { 
       @Override 
       public void onResult(@NonNull PlaceBuffer places) { 
        if (places.getStatus().isSuccess()) { 
         final Place myPlace = places.get(0); 
         Log.i(String.valueOf(PlaceDetailsFromSearch.this), 
           "Place found: " + myPlace.getName() + "\n Address: " + myPlace.getAddress()); 
         placeName = (String) myPlace.getName(); 
         tv_place_name.setText(placeName); 
         placeAddress = (String) myPlace.getAddress(); 
         tv_address.setText(placeAddress); 
         placeContact = (String) myPlace.getPhoneNumber(); 
         tv_call_info.setText(placeContact); 
         placeRating = myPlace.getRating(); 
         placeWeblink = String.valueOf(myPlace.getWebsiteUri()); 
         tv_website_info.setText(placeWeblink); 
         placeRating = myPlace.getRating(); 
         ratingBar.setRating(placeRating); 

        } else { 
         Log.i(String.valueOf(PlaceDetailsFromSearch.this), String.valueOf(places.getStatus())); 
        } 
        places.release(); 
       } 
      }); 
}} 

而這給了我一個錯誤沒有太多有關哪個String爲空的信息。

E/UncaughtException：java.lang.IllegalArgumentException異常：給定的字符串是空的，或者在android.os.Parcel.readException（Parcel.java:1688） 在android.os.Parcel.readException（包裹空 。 java：1637） at com.google.android.gms.location.places.internal.zzj $ zza $ zza.zzb（Unknown Source） at com.google.android.gms.location.places.internal.zzh.zza （Unknown Source）

Answer 1

替換它

placeId = extras.getString（「placeId」）;

通過

placeId = extras.getString（ 「placeID」）;

在的onCreate（）PlaceDetailsFromSearch.java活性方法。希望你的問題能夠解決。因爲您正在通過placeID作爲額外的PLaceSearch.java活動。
