本文介绍了谷歌自动完成地方的Andr​​oid +片段的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我在Android开发初学者，我到了，我希望你能帮助我解决问题。我会保持它的简单...我将尝试使用谷歌自动完成的地方在一个片段...应用程序从一开始就停止。我的猜测是，问题是，当我使用的方法 rebuildGoogleApiClient（），当我设置了 PlaceAutocompleteAdapter 之后。这里是我的code：

（ ActivityMap.java - 树立的GoogleMap和创建片段）

 公共类ActivityMap扩展AppCompatActivity {
        @覆盖
        保护无效的onCreate（捆绑savedInstanceState）{
            super.onCreate（savedInstanceState）;
            的setContentView（R.layout.activity_map）;            （......）        }        //创建片段
        私人无效选择信息（INT位置）{
            （......）
            MyFragment片段=新MyFragment（）;            FragmentManager fragmentManager = this.getSupportFragmentManager（）;
            FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction（）;
            fragmentTransaction.replace（R.id.content_frame，片段）;
            fragmentTransaction.commit（）;
        }    }

（ MyFragment.java - 包含 AutoCompleteTextView ）

 公共类MyFragment扩展片段实现GoogleApiClient.OnConnectionFailedListener，GoogleApiClient.ConnectionCallbacks {        查看rootView;
        AutoCompleteTextView的;
        GoogleApiClient mGoogleApiClient;
        PlaceAutocompleteAdapter mAdapter;        @覆盖
        公共查看onCreateView（LayoutInflater充气器，容器的ViewGroup，捆绑savedInstanceState）{            rootView = inflater.inflate（R.layout.myFragment，集装箱，FALSE）;            如果（mGoogleApiClient == NULL）{
                rebuildGoogleApiClient（）;
            }            从=（AutoCompleteTextView）rootView.findViewById（R.id.autoCompleteFrom）;            （......）            mAdapter =新PlaceAutocompleteAdapter（this.getActivity（），android.R.layout.simple_list_item_1，NULL，NULL）;
            from.setAdapter（mAdapter）;            返回rootView;
        }
        私人无效rebuildGoogleApiClient（）{
            mGoogleApiClient =新GoogleApiClient.Builder（this.getActivity（））enableAutoManage（this.getActivity（），0 / *的clientId * /，此）.addConnectionCallbacks（本）.addApi（Places.GEO_DATA_API）.build（）;
        }    }

（ PlaceAutocompleteAdapter - 适配器从地方地理数据API处理自动完成请求）

 公共类PlaceAutocompleteAdapter扩展ArrayAdapter＆LT; PlaceAutocompleteAdapter.PlaceAutocomplete＆GT;实现可筛选{        的LatLngBounds mBounds;
        AutocompleteFilter mPlaceFilter;        //构造
        公共PlaceAutocompleteAdapter（上下文的背景下，INT资源的LatLngBounds界限，AutocompleteFilter过滤器）{
            超（背景下，资源）;
            mBounds =界限;
            mPlaceFilter =滤波器;
        }
    }

（ activity_map.xml ）

 ＆LT;的LinearLayout
        机器人：layout_width =match_parent
        机器人：layout_height =match_parent＆GT;        ＆LT;的FrameLayout
            机器人：ID =@ + ID / content_frame
            机器人：layout_width =match_parent
            机器人：layout_height =match_parent＆GT;            ＆LT;片段
                机器人：ID =@ + ID /图
                机器人：名字=com.google.android.gms.maps.SupportMapFragment
                机器人：layout_width =match_parent
                机器人：layout_height =match_parent/＆GT;
        ＆LT; /＆的FrameLayout GT;
    ＆LT; / LinearLayout中＆GT;

（my_fragment.xml）

 ＆LT; RelativeLayout的
        机器人：layout_width =match_parent
        机器人：layout_height =match_parent＆GT;        ＆LT;的TextView
            机器人：ID =@ + ID /来自
            机器人：layout_width =WRAP_CONTENT
            机器人：layout_height =WRAP_CONTENT
            机器人：文字=从/＆GT;        ＆LT; AutoCompleteTextView
            机器人：ID =@ + ID / autoCompleteFrom
            机器人：layout_width =match_parent
            机器人：layout_height =WRAP_CONTENT
            机器人：completionThreshold =2/＆GT;
    ＆LT; / RelativeLayout的＆GT;

让我知道，如果你需要一些额外的信息或额外的code和提前谢谢你。

解决方案

我认为问题是，你使用 enableAutoManage（）在 Fragment.onCreateView（）。

相反，我会建议如下：


  • 实例化 GoogleApiClient 在 Fragment.onCreate（）

  • 通话 mGoogleApiClient.connect（）在 Fragment.onStart（）

  • 通话 mGoogleApiClient.disconnect（）在 Fragment.onStop（）

请参阅 https://developers.google.com/places/android/start ＃连接的客户端了解详情。

我希望这有助于！

I am a beginner on Android development and I came into a problem which I hope you can help me to solve. I'll keep it simple...i am trying to use Google Places autocompletion in a fragment...the app stops right from the beginning. My guess is the problem is when I use the method rebuildGoogleApiClient() and when I set up the PlaceAutocompleteAdapter after that. Here is my code:

(ActivityMap.java - sets up the GoogleMap and creates the fragment)

    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 - contains the 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 - Adapter that handles Autocomplete requests from the Places Geo Data API )

    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>

解决方案

I believe the problem is that you're using enableAutoManage() in Fragment.onCreateView().

Instead, I would recommend the following:

  • instantiate the GoogleApiClient in Fragment.onCreate()
  • call mGoogleApiClient.connect() in in Fragment.onStart()
  • call mGoogleApiClient.disconnect() in Fragment.onStop()

See https://developers.google.com/places/android/start#connect-client for details.

I hope this helps!
