【问题描述】：

我目前正在开发有关谷歌地图服务的应用程序。我使用带有 2 个选项卡的选项卡布局，这些选项卡是片段。 在一个标签中，我使用谷歌地图 api，它工作正常。 但是在第二个选项卡中，我希望在按钮上单击带有位置选择器的启动意图。单击它会出现 1 秒钟，然后隐藏。我不知道是什么问题，所以请帮忙。

代码如下：

主活动：

public class MainActivity extends AppCompatActivity 

    /**
     * The @link android.support.v4.view.PagerAdapter that will provide
     * fragments for each of the sections. We use a
     * @link FragmentPagerAdapter derivative, which will keep every
     * loaded fragment in memory. If this becomes too memory intensive, it
     * may be best to switch to a
     * @link android.support.v4.app.FragmentStatePagerAdapter.
     */
    private SectionsPagerAdapter mSectionsPagerAdapter;

    /**
     * The @link ViewPager that will host the section contents.
     */
    private ViewPager mViewPager;

    @Override
    protected void onCreate(Bundle savedInstanceState) 
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        // Create the adapter that will return a fragment for each of the three
        // primary sections of the activity.
        mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());

        // Set up the ViewPager with the sections adapter.
        mViewPager = (ViewPager) findViewById(R.id.container);
        mViewPager.setAdapter(mSectionsPagerAdapter);

        TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
        tabLayout.setupWithViewPager(mViewPager);

//        FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
//        fab.setOnClickListener(new View.OnClickListener() 
//            @Override
//            public void onClick(View view) 
//                Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
//                        .setAction("Action", null).show();
//            
//        );

    


    @Override
    public boolean onCreateOptionsMenu(Menu menu) 
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    

    @Override
    public boolean onOptionsItemSelected(MenuItem item) 
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) 
            return true;
        

        return super.onOptionsItemSelected(item);
    

    /**
     * A @link FragmentPagerAdapter that returns a fragment corresponding to
     * one of the sections/tabs/pages.
     */
    public class SectionsPagerAdapter extends FragmentPagerAdapter 

        public SectionsPagerAdapter(FragmentManager fm) 
            super(fm);
        

        @Override
        public Fragment getItem(int position) 
            switch (position) 
                case 0:
                    TabDirectionsActivity tabDirectionsActivity = new TabDirectionsActivity();
                    return tabDirectionsActivity;
                case 1:
                    TabPlacesActivity tabPlacesActivity = new TabPlacesActivity();
                    return tabPlacesActivity;
                default:
                    return  null;
            
        

        @Override
        public int getCount() 
            // Show 2 total pages.
            return 2;
        

        @Override
        public CharSequence getPageTitle(int position) 
            switch (position) 
                case 0:
                    return "DIRECTIONS";
                case 1:
                    return "PLACES";
            
            return null;
        
    

这是 TabPlaces 片段：

public class TabPlacesActivity extends Fragment 

    TextView placeNameText;
    TextView placeAddressText;
    WebView attributionText;
    Button getPlaceButton;
    private final static int PLACE_PICKER_REQUEST = 1;

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) 

        View placesView = inflater.inflate(R.layout.activity_places, container, false);

        placeNameText = (TextView) placesView.findViewById(R.id.tv_PlaceName);
        placeAddressText = (TextView) placesView.findViewById(R.id.tv_PlaceAddress);
        attributionText = (WebView) placesView.findViewById(R.id.wv_Attribution);
        getPlaceButton = (Button) placesView.findViewById(R.id.btn_GetPlace);

        getPlaceButton.setOnClickListener(new View.OnClickListener() 
            @Override
            public void onClick(View view) 
                PlacePicker.IntentBuilder builder = new PlacePicker.IntentBuilder();
                try 
                    Intent intent = builder.build(getActivity());
                    startActivityForResult(intent, PLACE_PICKER_REQUEST);
                 catch (GooglePlayServicesRepairableException e) 
                    e.printStackTrace();
                 catch (GooglePlayServicesNotAvailableException e) 
                    e.printStackTrace();
                

            
        );

        return placesView;

    

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) 
        if (requestCode == PLACE_PICKER_REQUEST)
            if (resultCode == getActivity().RESULT_OK)
                Place place = PlacePicker.getPlace(getActivity(),data);
                placeNameText.setText(place.getName());
                placeAddressText.setText(place.getAddress());
                if (place.getAttributions() == null) 
                    attributionText.loadData("no attribution", "text/html; charset=utf-8", "UFT-8");
                 else 
                    attributionText.loadData(place.getAttributions().toString(), "text/html; charset=utf-8", "UFT-8");
                
            
        
    

这里是activity_places.xml：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_
    android:layout_
    android:orientation="vertical"
    tools:context="rs.fon.mapapp.TabPlacesActivity"
    android:gravity="top|center">

    <Button
        android:id="@+id/btn_GetPlace"
        android:layout_
        android:layout_
        android:text="Get Place" />

    <TextView
        android:id="@+id/tv_PlaceName"
        android:layout_
        android:layout_
        android:layout_marginTop="80dp"
        android:text="Place Name"
        android:textSize="16sp"
        android:textStyle="bold" />

    <TextView
        android:id="@+id/tv_PlaceAddress"
        android:layout_
        android:layout_
        android:text="Place Address"
        android:textSize="16sp" />

    <WebView
        android:id="@+id/wv_Attribution"
        android:layout_
        android:layout_
        android:text="Attribution"
        android:textSize="16sp" />


</LinearLayout>

【参考方案1】：

我找到了解决方案。 解决方案是我必须在 Manifest 文件中重命名我的元数据

<meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="YOUR API KEY" />

改成

<meta-data android:name="com.google.android.geo.API_KEY"
            android:value="YOUR ANOTHER API KEY"
            />

并删除签名

<permission
        android:name="rs.fon.mapapp.permission.MAPS_RECEIVE"
        android:protectionLevel="signature" />

    <uses-permission android:name="rs.fon.mapapp.permission.MAPS_RECEIVE" />
