我的问题很简单，我在我的 XML 中添加了 4 个 FrameLayout，并在这些容器中通过代码添加了 4 个 MapFragment。

像这样:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:map="http://schemas.android.com/apk/res-auto"
  android:id="@+id/map_container"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:orientation="vertical">
  <LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_weight="0.5"
    android:orientation="horizontal">
    <FrameLayout
      android:id="@+id/map1_container"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:layout_weight="0.5""/>
    <FrameLayout
      android:id="@+id/map2_container"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:layout_weight="0.5"/>
  </LinearLayout>
  <LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_weight="0.5"
    android:orientation="horizontal">
    <fragment
      android:id="@+id/map3_container"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:layout_weight="0.5"/>
    <fragment
      android:id="@+id/map4_container"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:layout_weight="0.5""/>
  </LinearLayout>

在我的 Activity 中

public class MultiGoogleMapActivity extends FragmentActivity {

    private GoogleMap mMap;
    private GoogleMap mMapUp;
    private GoogleMap mMapMiddle;
    private GoogleMap mMapLow;

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

mMap1Fragment = SupportMapFragment.newInstance();
    FragmentTransaction fragmentTransaction = getSupportFragmentManager()
                        .beginTransaction();
                fragmentTransaction.add(R.id.map1_container, mMap1Fragment, MAP_FRAGMENT_TAG);
                fragmentTransaction.commit();
mMap2Fragment = SupportMapFragment.newInstance(new GoogleMapOptions().zoomControlsEnabled(false).zoomGesturesEnabled(false).compassEnabled(false).rotateGesturesEnabled(false).scrollGesturesEnabled(false));
    FragmentTransaction fragmentTransaction = getSupportFragmentManager()
                        .beginTransaction();
                fragmentTransaction.add(R.id.map2_container, mMap2Fragment, MAP_FRAGMENT_TAG);
                fragmentTransaction.commit();
mMap3Fragment = SupportMapFragment.newInstance(new GoogleMapOptions().zoomControlsEnabled(false).zoomGesturesEnabled(false).compassEnabled(false).rotateGesturesEnabled(false).scrollGesturesEnabled(false));
    FragmentTransaction fragmentTransaction = getSupportFragmentManager()
                        .beginTransaction();
                fragmentTransaction.add(R.id.map3_container, mMap3Fragment, MAP_FRAGMENT_TAG);
                fragmentTransaction.commit();
mMap4Fragment = SupportMapFragment.newInstance(new GoogleMapOptions().zoomControlsEnabled(false).zoomGesturesEnabled(false).compassEnabled(false).rotateGesturesEnabled(false).scrollGesturesEnabled(false));
    FragmentTransaction fragmentTransaction = getSupportFragmentManager()
                        .beginTransaction();
                fragmentTransaction.add(R.id.map4_container, mMap4Fragment, MAP_FRAGMENT_TAG);
                fragmentTransaction.commit();

        setUpMapIfNeeded();
    }

    @Override
    protected void onResume() {
        super.onResume();
        setUpMapIfNeeded();
    }

    private void setUpMapIfNeeded() {
        // Do a null check to confirm that we have not already instantiated the
        // map.
        if (mMap == null) {
            mMap = mMap1Fragment.getMap();
        }
        if (mMapUp == null) {
            mMapUp = mMap2Fragment.getMap();
            mMapUp.setOnMapClickListener(new OnMapClickListener() {

                public void onMapClick(LatLng arg0) {
                    CameraPosition cp = mMapUp.getCameraPosition();
                    mMapUp.moveCamera(CameraUpdateFactory.newCameraPosition(mMap.getCameraPosition()));

                public void onCameraChange(CameraPosition arg0) {
                    mMapUp.animateCamera(CameraUpdateFactory.newLatLngBounds(
                            new LatLngBounds(new LatLng(-21.417276,55.039925),
                                        new LatLng(-20.815174,56.008095)),

                    mMapLow.setOnCameraChangeListener(null);
                }
            });

        }

    }

}

问题是:当我旋转设备时，MapFragments 不再响应触摸事件...

有没有人遇到同样的问题并解决了？

最佳答案

我遇到了同样的问题，经过多次故障排除后发现容器中有多个 map fragment 。

所以，我通过使用解决了这个问题

FragmentTransaction.replace

代替

.add

关于android - 旋转后 MapFragment 变得无响应，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/14242209/
