定位+拖動(dòng)定位

定位動(dòng)畫

動(dòng)畫結(jié)束顯示地址

中心點(diǎn)不變，在百度地圖圖層上覆蓋自定義的定位布局
（TextView＋I(xiàn)mageView＋I(xiàn)mageView）

拖動(dòng)地圖時(shí)，隱藏地址顯示，定位標(biāo)示落下來后顯示地址

拿到百度地圖的拖動(dòng)監(jiān)聽 setOnMapStatusChangeListener

拿到中心點(diǎn)經(jīng)緯度，逆地理編碼（即坐標(biāo)轉(zhuǎn)地址）mapStatus.target

在主界面布局上覆蓋自己定位用的布局location_marker

location_marker布局：三個(gè)控件

創(chuàng)建地理編碼檢索實(shí)例；

創(chuàng)建地理編碼檢索監(jiān)聽者；

開始向上的動(dòng)畫

停止拖動(dòng)后，發(fā)起地理編碼檢索

mBaiduMap.setOnMapStatusChangeListener(new BaiduMap.OnMapStatusChangeListener() {
            @Override
            public void onMapStatusChangeStart(MapStatus mapStatus) {
                mSearch = GeoCoder.newInstance();
                mSearch.setOnGetGeoCodeResultListener(listener);
                startUpAnimation(new Animation.AnimationListener() {
                    @Override
                    public void onAnimationStart(Animation animation) {
                        ／／動(dòng)畫開始時(shí)，隱藏地址顯示
                        tv_describe.setVisibility(View.INVISIBLE);
                    }

                    @Override
                    public void onAnimationEnd(Animation animation) {

                    }

                    @Override
                    public void onAnimationRepeat(Animation animation) {

                    }
                });

            }

            @Override
            public void onMapStatusChangeStart(MapStatus mapStatus, int i) {

            }

            @Override
            public void onMapStatusChange(MapStatus mapStatus) {

            }

            @Override
            public void onMapStatusChangeFinish(MapStatus mapStatus) {

                mSearch.reverseGeoCode(new ReverseGeoCodeOption()
                        .location(mapStatus.target));



            }
        });

地理位置編碼檢索監(jiān)聽實(shí)現(xiàn)：

OnGetGeoCoderResultListener listener = new OnGetGeoCoderResultListener() {

        public void onGetGeoCodeResult(GeoCodeResult result) {

            if (result == null || result.error != SearchResult.ERRORNO.NO_ERROR) {
                //沒有檢索到結(jié)果
            }

            //獲取地理編碼結(jié)果
        }

        @Override

        public void onGetReverseGeoCodeResult(ReverseGeoCodeResult result) {

            if (result == null || result.error != SearchResult.ERRORNO.NO_ERROR) {
                //沒有找到檢索結(jié)果
                Toast.makeText(MainActivity.this,"沒有找到檢索結(jié)果",Toast.LENGTH_SHORT).show();
            }

            //獲取反向地理編碼結(jié)果
            String address = result.getAddress();
            System.out.println(address+"---------");
            tv_describe.setText(address);
            startDownAnimation(new Animation.AnimationListener() {
                @Override
                public void onAnimationStart(Animation animation) {

                }

                @Override
                public void onAnimationEnd(Animation animation) {
                    tv_describe.setVisibility(View.VISIBLE);
                    bounce();
                }

                @Override
                public void onAnimationRepeat(Animation animation) {

                }
            });

        }
    };

需要一個(gè)變量紀(jì)錄是否向上

    private boolean isUp = false;

    /**
     * 向上移動(dòng)動(dòng)畫
     */
    public void startUpAnimation(Animation.AnimationListener listener){
        if (isUp){
            return;
        }
        Animation animation = new TranslateAnimation(
                0,
                0,
                0  ,
                - 80);
        animation.setDuration(500);
        animation.setFillAfter(true);//設(shè)置為true，動(dòng)畫轉(zhuǎn)化結(jié)束后被應(yīng)用
        animation.setInterpolator(new AccelerateDecelerateInterpolator());
        iv_location.startAnimation(animation);//開始動(dòng)畫
        if(listener != null){
            animation.setAnimationListener(listener);
        }

        isUp = true;
    }

    /**
     * 向下移動(dòng)動(dòng)畫
     */
    public void startDownAnimation(Animation.AnimationListener listener){
        if(isUp){
            Animation animation = new TranslateAnimation(
                    0,
                    0,
                    -80,
                    0);
            animation.setDuration(500);
            animation.setFillAfter(true);//設(shè)置為true，動(dòng)畫轉(zhuǎn)化結(jié)束后被應(yīng)用
            animation.setInterpolator(new AccelerateInterpolator(15));
            if(listener != null){
                animation.setAnimationListener(listener);
            }
            iv_location.startAnimation(animation);//開始動(dòng)畫
            isUp = false;
        }
    }

    /**
     * 彈跳動(dòng)畫
     */
    public  void bounce() {
        if (iv_location.getVisibility() == View.VISIBLE) {
            ObjectAnimator animator = ObjectAnimator.ofFloat(iv_location, "translationY", 0, -30, 0);
            animator.setInterpolator(new EasingInterpolator(EasingInterpolator.Ease.ELASTIC_IN_OUT));

            animator.setDuration(1000);
            animator.setRepeatMode(ValueAnimator.REVERSE);
            animator.start();
        }
    }

新添加一個(gè)變量紀(jì)錄是否第一次定位

private boolean isFirst = true;
    class MyLocationListener extends BDAbstractLocationListener {


        @Override
        public void onReceiveLocation(BDLocation bdLocation) {

            MyLocationData locData = new MyLocationData.Builder()
                    .accuracy(bdLocation.getRadius())
                    // 此處設(shè)置開發(fā)者獲取到的方向信息，順時(shí)針0-360
                    .direction(bdLocation.getDirection()).latitude(bdLocation.getLatitude())
                    .longitude(bdLocation.getLongitude()).build();
            mBaiduMap.setMyLocationData(locData);

            String addr = bdLocation.getAddrStr();    //獲取詳細(xì)地址信息
            String country = bdLocation.getCountry();    //獲取國家
            String province = bdLocation.getProvince();    //獲取省份
            String city = bdLocation.getCity();    //獲取城市
            String district = bdLocation.getDistrict();    //獲取區(qū)縣
            String street = bdLocation.getStreet();    //獲取街道信息
//            showMyLocate(locData);

            if(isFirst){
                // 開始移動(dòng)百度地圖的定位地點(diǎn)到中心位置
                LatLng ll = new LatLng(bdLocation.getLatitude(), bdLocation.getLongitude());
                MapStatusUpdate u = MapStatusUpdateFactory.newLatLngZoom(ll,16);
                mBaiduMap.animateMapStatus(u);
                isFirst = false;
            }

        }
    }
}
