如何在谷歌地图中禁用两指滚动

我正在尝试在我的应用程序中实现谷歌地图，其中我想在谷歌地图中禁用两根手指滚动。这意味着如果用户用一根手指触摸地图，则地图应该滚动，如果用户用两根手指触摸地图，则不应滚动。 谢谢！

您可以在 GoogleMap 上启用/禁用滚动手势，您可以通过调用setAllGesturesEnabled() and setScrollGesturesEnabled() on GoogleMap.getUiSettings()物体并用于确定两个手指的触摸MapFragment您可以使用基于自定义地图片段的方法this https://stackoverflow.com/a/14538765/6950238社区维基的回答：

public class TouchableWrapper extends FrameLayout {

    private GoogleMap mGoogleMap = null;

    public TouchableWrapper(Context context) {
        super(context);
    }

    public void setGoogleMap(GoogleMap googleMap) {
        mGoogleMap = googleMap;
    }

    @Override
    public boolean dispatchTouchEvent(MotionEvent event) {

        switch (event.getAction() & MotionEvent.ACTION_MASK) {

            case MotionEvent.ACTION_DOWN:
                mGoogleMap.getUiSettings().setScrollGesturesEnabled(true);
            break;

            case MotionEvent.ACTION_POINTER_DOWN:
                // disabling scroll gestures in case second finger down
                mGoogleMap.getUiSettings().setScrollGesturesEnabled(false);
            break;

            case MotionEvent.ACTION_POINTER_UP:
                mGoogleMap.getUiSettings().setScrollGesturesEnabled(true);
            break;

            case MotionEvent.ACTION_UP:
                mGoogleMap.getUiSettings().setScrollGesturesEnabled(true);
            break;
        }

        return super.dispatchTouchEvent(event);
    }
}

MapFragment为此应该定制如下：

public class MultiTouchMapFragment extends MapFragment {
    public View mOriginalContentView;
    public TouchableWrapper mTouchView;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup parent, Bundle savedInstanceState) {
        mOriginalContentView = super.onCreateView(inflater, parent, savedInstanceState);
        mTouchView = new TouchableWrapper(getActivity());
        mTouchView.addView(mOriginalContentView);
        return mTouchView;
    }

    @Override
    public View getView() {
        return mOriginalContentView;
    }
}

activity_main.xml for MainActivity可以是这样的：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="{YOUR_PACKAGE_NAME}.MainActivity">

    <fragment
        android:id="@+id/map_fragment"
        android:name="{YOUR_PACKAGE_NAME}.MultiTouchMapFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

</RelativeLayout>

并且没有任何变化MainActivity:

public class MainActivity extends AppCompatActivity implements OnMapReadyCallback {

    private GoogleMap mGoogleMap;
    private MultiTouchMapFragment mMapFragment;

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

        mMapFragment = (MultiTouchMapFragment) getFragmentManager()
                .findFragmentById(R.id.map_fragment);
        mMapFragment.getMapAsync(this);
    }

    @Override
    public void onMapReady(GoogleMap googleMap) {
        mGoogleMap = googleMap;
        mMapFragment.mTouchView.setGoogleMap(mGoogleMap);
    }

}

此外，您可以使用相同的解决方案进行定制MapView（如果你使用它）。
