我是Android开发的初学者，遇到了一个问题，希望您能帮助我解决。我会保持简单...我正在尝试在片段中使用 Google Places 自动完成功能...该应用程序从一开始就停止了。我的猜测是问题在于我何时使用该方法rebuildGoogleApiClient()以及何时设置该方法PlaceAutocompleteAdapter。这是我的代码：
（ActivityMap.java- 设置 GoogleMap 并创建片段）
public class ActivityMap extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_map);
(...)
}
//creates fragment
private void selectItem(int position) {
(...)
MyFragment fragment = new MyFragment();
FragmentManager fragmentManager = this.getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.content_frame, fragment);
fragmentTransaction.commit();
}
}
( MyFragment.java- 包含AutoCompleteTextView)
public class MyFragment extends Fragment implements GoogleApiClient.OnConnectionFailedListener, GoogleApiClient.ConnectionCallbacks {
View rootView;
AutoCompleteTextView from;
GoogleApiClient mGoogleApiClient;
PlaceAutocompleteAdapter mAdapter;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
rootView = inflater.inflate(R.layout.myFragment, container, false);
if (mGoogleApiClient == null) {
rebuildGoogleApiClient();
}
from = (AutoCompleteTextView) rootView.findViewById(R.id.autoCompleteFrom);
(...)
mAdapter = new PlaceAutocompleteAdapter(this.getActivity(), android.R.layout.simple_list_item_1, null, null);
from.setAdapter(mAdapter);
return rootView;
}
private void rebuildGoogleApiClient() {
mGoogleApiClient = new GoogleApiClient.Builder(this.getActivity()).enableAutoManage(this.getActivity(), 0 /* clientId */, this).addConnectionCallbacks(this).addApi(Places.GEO_DATA_API).build();
}
}
（PlaceAutocompleteAdapter- 处理来自 Places Geo Data API 的自动完成请求的适配器）
public class PlaceAutocompleteAdapter extends ArrayAdapter<PlaceAutocompleteAdapter.PlaceAutocomplete> implements Filterable {
LatLngBounds mBounds;
AutocompleteFilter mPlaceFilter;
//constructor
public PlaceAutocompleteAdapter(Context context, int resource,LatLngBounds bounds, AutocompleteFilter filter) {
super(context, resource);
mBounds = bounds;
mPlaceFilter = filter;
}
}
( activity_map.xml)
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:id="@+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent">
<fragment
android:id="@+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</FrameLayout>
</LinearLayout>
(my_fragment.xml)
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:id="@+id/from"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="From" />
<AutoCompleteTextView
android:id="@+id/autoCompleteFrom"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:completionThreshold="2" />
</RelativeLayout>
如果您需要一些额外的信息或额外的代码，请告诉我，并提前感谢您。
