Question

我正在尝试在片段中设置Google地图并遇到一些问题，试图让按钮正确收听。我有以下代码：

Array ( [update_slider] => Update Slider [DSCF3727_jpg] => 0 [DSCF3687_jpg] => 0 [DSCF3744_jpg] => 0 [DSCF4070_jpg] => 0 [DSCF4071_jpg] => 0 [DSCF4073_jpg] => 0 [10245379_229236400605097_7329379469957650735_n_jpg] => 0 [10314007_229236253938445_8056225029697636541_n_jpg] => 0 [DSCF3618_jpg] => 0 [10550825_261238134071590_1715454340087601479_n_jpg] => 0 [1551739_261238150738255_2482363522486143465_n_jpg] => 0 [10626882_284760908385979_3153917771920003400_n_jpg] => 0 [10689730_284760921719311_8515870397004989019_n_jpg] => 0 [DSCF3384_jpg] => 0 [DSCF3382_jpg] => 0 [biker_jpg] => 0 [10410927_255245578004179_6557207701489592736_n_jpg] => 0 [10400847_255245548004182_5319163275713658480_n_jpg] => 0 [111111_jpg] => 0 [DSCF3013_jpg] => 0 [DSCF4040_jpg] => 0 [1011255_238047056390698_6002378516798338793_n_jpg] => 0 [10373785_238048733057197_8255990183542589096_n_jpg] => 0 [10383572_238047003057370_1041466926744898970_n_jpg] => 0 [DSCF4047_jpg] => 0 [DSCF4051_jpg] => 0 [DSCF4109_jpg] => 0 [DSCF4121_jpg] => 0 [DSCF4136_jpg] => 0 [DSCF4029_jpg] => 0 [Rancho-las-lomas-wedding-DJ_jpg] => 0 [webtest_jpg] => 0 ) DSCF3727_jpg

map_fragment.xml的相关部分：

public DefaultMap extends android,.support.v4.app.Fragment implements OnMapReadyCallback {
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        View v = inflater.inflate(R.layout.map_fragment, container, false);

        MapsInitializer.initialize(getActivity());

        // Obtain the SupportMapFragment and get notified when the map is ready to be used.
        mMapFragment = new SupportMapFragment() {
            @Override
            public void onActivityCreated(Bundle savedInstanceState) {
                super.onActivityCreated(savedInstanceState);
                mMap = mMapFragment.getMap();
                if (mMap != null) {

                }
            }
        };

        mMapFragment.getMapAsync(this);
//        mAutocompleteView = (AutoCompleteTextView) findViewById(R.id.TFSearch);
//        mAutocompleteView.setAdapter(new PlaceAutocompleteAdapter(this, android.R.layout.simple_dropdown_item_1line));
        searchSetup(v);
        zoomSetup(v);
        setupMapType(v);
        return v;
    }
    //an example of one of the setup functions
    public void setupMapType(View view) {
        typeMapButton = (Button) view.findViewById(R.id.TFtype);
        typeMapButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (mMap.getMapType() == GoogleMap.MAP_TYPE_NORMAL) {
                    mMap.setMapType(GoogleMap.MAP_TYPE_SATELLITE);
                } else {
                    mMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
                }
            }
        });
    }
}

单击按钮时我收到以下错误（所有4个按钮都相同）：

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    xmlns:tools="http://schemas.android.com/tools">

        tools:context=".DefaultMap"
        android:name="com.google.android.gms.maps.SupportMapFragment"
        />

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal">
        <LinearLayout
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:orientation="horizontal">

            <Button
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="@string/map_type"
                android:id="@+id/TFtype"
                android:onClick="onTypeMap"
                tools:context=".DefaultMap"
                android:layout_marginRight="5dp" />
        </LinearLayout>

    </LinearLayout>

</FrameLayout>

有人知道如何解决这些问题吗？

Answer 1

使用SupportMapFragment.newInstance()获取SupportMapFragment的新实例，以便从Fragment中添加它，并从android:name="com.google.android.gms.maps.SupportMapFragment"片段的xml中删除DefaultMap。
