从底部滑动视图到另一个布局

Question

我的应用程序有一个显示 Google 地图和当前位置的父布局，还有一个子布局，它从屏幕底部向上移动到 google 地图，但只显示到屏幕的一半。我设法用下面的代码做到了这一切。

上下滑动动画：

slide_down.xml

 <?xml version="1.0" encoding="utf-8"?>
    <set xmlns:android="http://schemas.android.com/apk/res/android">
        <objectAnimator
                android:interpolator="@android:anim/accelerate_decelerate_interpolator"
                android:propertyName="yFraction"
                android:valueType="floatType"
                android:valueFrom="0.58"
                android:valueTo="1.0"
                android:duration="@android:integer/config_mediumAnimTime"/>
        <objectAnimator
                android:interpolator="@android:anim/accelerate_decelerate_interpolator"
                android:propertyName="alpha"
                android:valueType="floatType"
                android:valueFrom="1"
                android:valueTo="0"
                android:duration="@android:integer/config_mediumAnimTime"/>
    </set>

slide_up.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <objectAnimator
            android:interpolator="@android:anim/accelerate_decelerate_interpolator"
            android:propertyName="yFraction"
            android:valueType="floatType"
            android:valueFrom="1.0"
            android:valueTo="0.58"
            android:duration="@android:integer/config_mediumAnimTime"/>
    <objectAnimator
            android:interpolator="@android:anim/accelerate_decelerate_interpolator"
            android:propertyName="alpha"
            android:valueType="floatType"
            android:valueFrom="0.58"
            android:valueTo="1.0"
            android:duration="@android:integer/config_mediumAnimTime"/>
</set>

主要Activity:

     public class MainActivity extends FragmentActivity implements LocationListener{

            GoogleMap googleMap;
            private static final String LIST_FRAGMENT_TAG = "list_fragment";
            Location mlocation;
            String mLastUpdateTime;
            double latitude;
            double longitude;
            int Radius = 100;
        Boolean flag = false ;



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

                SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.maps);
                googleMap = mapFragment.getMap();
                googleMap.setMyLocationEnabled(true);

                LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);

                Criteria criteria = new Criteria();
                String bestProvider = locationManager.getBestProvider(criteria, true);
                mlocation = locationManager.getLastKnownLocation(bestProvider);
                if (mlocation != null) {
                    onLocationChanged(mlocation);
                }
                locationManager.requestLocationUpdates(bestProvider, 20000, 0, this);

   }

            @Override
            public void onLocationChanged(Location location) {
                mlocation = location;
                latitude = location.getLatitude();

                longitude = location.getLongitude();
                LatLng latLng = new LatLng(latitude, longitude);
                long atTime = mlocation.getTime();
                mLastUpdateTime = DateFormat.getTimeInstance().format(new Date(atTime));

                googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
                View marker = ((LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.custom_marker_layout, null);

                CameraPosition INIT =
                        new CameraPosition.Builder()
                                .target(latLng)
                                .zoom(17.5F)
                                .bearing(300F) // orientation
                                .tilt(50F) // viewing angle
                                .build();
                googleMap.moveCamera(CameraUpdateFactory.newCameraPosition(INIT));

                googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(latLng, 13));

                googleMap.addMarker(new MarkerOptions()
                        .position(latLng)
        //                .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_ORANGE))
                        .icon(BitmapDescriptorFactory.fromBitmap(createDrawableFromView(this, marker)))
                        .title(getAdress())
                .snippet("Radius: " + Radius)).showInfoWindow();

                googleMap.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener() {

                    @Override
                    public boolean onMarkerClick(Marker marker) {
                        flag = true;
                        toggleList();
                        return true;
                    }

                });

                if(flag == false){
                    googleMap.getUiSettings().setAllGesturesEnabled(true);

                }

            private void toggleList() {
                Fragment f = getFragmentManager().findFragmentByTag(LIST_FRAGMENT_TAG);
                googleMap.getUiSettings().setAllGesturesEnabled(true);




                if (f != null) {
                    getFragmentManager().popBackStack();
                } else {
                    getFragmentManager().beginTransaction()
                            .setCustomAnimations(R.animator.slide_up,
                                    R.animator.slide_down,
                                    R.animator.slide_up,
                                    R.animator.slide_down)
                    .add(R.id.list_fragment_container, SlidingListFragment
                                    .instantiate(this, SlidingListFragment.class.getName()),
                            LIST_FRAGMENT_TAG
                            )


                            .addToBackStack(null).commit();
                    googleMap.getUiSettings().setAllGesturesEnabled(false);

                }

子布局

<?xml version="1.0" encoding="utf-8"?>

<com.trickyandroid.fragmenttranslate.app.view.SlidingRelativeLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="fill_parent"
    android:id="@+id/hidden_panel"
    android:background="#ffffffff">

    <ListView
            android:id="@android:id/list"
            android:layout_width="match_parent"
            android:layout_height="match_parent"/>

</com.trickyandroid.fragmenttranslate.app.view.SlidingRelativeLayout>

父布局

    <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="com.trickyandroid.fragmenttranslate.app.MainActivity">
    <fragment
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/maps"
        class="com.google.android.gms.maps.SupportMapFragment"/>

        <FrameLayout
                android:id="@+id/list_fragment_container"
                android:layout_width="match_parent"
                android:layout_height="match_parent"/>

    </RelativeLayout>

Problem is

如果地图是放大扩展那如果子布局向上滑动那么我的地图标记隐藏在子布局后面。我想在这种情况下，我的地图应该不会自动向上滑动。

Just like Whatsspp chat window . When we click for keyboard in it , chat window slide upward automatically or Friend Locator App .

Answer 1

我认为你应该先放大到地图中的标记，然后显示向上滑动动画。

您可以使用此 link 缩放到某个位置。

Google Maps v2 - set both my location and zoom in

CameraUpdate center=
    CameraUpdateFactory.newLatLng(new LatLng(40.76793169992044,
                                             -73.98180484771729));
CameraUpdate zoom=CameraUpdateFactory.zoomTo(15);

map.moveCamera(center);
map.animateCamera(zoom);

从底部滑动视图到另一个布局
