更换地图主题
将设置好的主题样式放入assets中
代码中(在setContentView(R.layout.activity_main)之前调用)
private void initBaiduMap(){
SDKInitializer.initialize(this);
new Thread(new Runnable() {
@Override
public void run() {
try
{
File mapStyleFile = new File(getFilesDir().getAbsolutePath() + "/custom_config_dark.txt");//主题样式的
if(!mapStyleFile.exists()) {
InputStream is = getAssets().open("customConfigdir/custom_config_dark.txt");
FileOutputStream fos = new FileOutputStream(mapStyleFile);
byte[] buffer = new byte[1024];
int byteCount = 0;
while ((byteCount = is.read(buffer)) != -1) {//循环从输入流读取 buffer字节
fos.write(buffer, 0, byteCount);//将读取的输入流写入到输出流
}
fos.flush();//刷新缓冲区
is.close();
fos.close();
}
TextureMapView.setCustomMapStylePath(mapStyleFile.getAbsolutePath());
TextureMapView.setMapCustomEnable(true);
} catch (Exception e){
e.printStackTrace();
}
}
}).start();
}
最后在需要出现这个地图主题的ativity中
map.setMapCustomEnable(true); //设置个性化地图样式是否生效
去除logo
View child = map.getChildAt(1);
if (child != null && (child instanceof ImageView || child instanceof ZoomControls))
{
child.setVisibility(View.INVISIBLE);
}
多个market的点击事件
循环设置market
private void setMarket(latitude,longitude)
{
LatLng point = new LatLng(latitude, longitude);
//定义Maker坐标点
// //构建Marker图标
BitmapDescriptor bitmap = BitmapDescriptorFactory.fromResource(R.mipmap.ic_empoison_commonly);
//构建MarkerOption,用于在地图上添加Marker
OverlayOptions options = new MarkerOptions()
.position(point) //设置marker的位置
.icon(bitmap) //设置marker图标
// .zIndex(2) //设置marker所在层级
.draggable(false); //设置手势拖拽
//在地图上添加Marker,并显示
Overlay marker = mBaiduMap.addOverlay(options);
Bundle bundle = new Bundle();
bundle.putSerializable("point", point);
marker.setExtraInfo(bundle);
}
private void setCircle(latitude,longitude)
{
LatLng point = new LatLng(latitude,longitude);
int circleColor = 0;
switch (dataMap.type)
{
case 1:
circleColor = getResources().getColor(R.color.item_good);
break;
case 2:
circleColor = getResources().getColor(R.color.item_opacitas);
break;
case 3:
circleColor = getResources().getColor(R.color.item_alga);
break;
case 4:
circleColor = getResources().getColor(R.color.item_element);
break;
}
OverlayOptions ooCircle = new CircleOptions()
.fillColor(circleColor)
.center(point)
// .stroke(new Stroke(5, circleColor))
.radius(1400);
mBaiduMap.addOverlay(ooCircle);
}
onCreate中设置mBaiduMap的监听
mBaiduMap.setOnMarkerClickListener(new BaiduMap.OnMarkerClickListener()
{
@Override
public boolean onMarkerClick(Marker marker)
{
DataMap dataMap = (DataMap) marker.getExtraInfo().get("point");
return true;
}
});
百度地图在listview/recyclerview的滑动冲突
mBaiduMap.setOnMapStatusChangeListener(new BaiduMap.OnMapStatusChangeListener()
{
LatLng startLng, finishLng;
@Override
public void onMapStatusChangeStart(MapStatus mapStatus)
{
startLng = mapStatus.target;
}
@Override
public void onMapStatusChange(MapStatus mapStatus)
{
}
@Override
public void onMapStatusChangeFinish(MapStatus mapStatus)
{
// 滑动搜索
finishLng = mapStatus.target;
if (startLng.latitude != finishLng.latitude
|| startLng.longitude != finishLng.longitude)
{
Projection ject = mBaiduMap.getProjection();
Point startPoint = ject.toScreenLocation(startLng);
Point finishPoint = ject.toScreenLocation(finishLng);
double x = Math.abs(finishPoint.x - startPoint.x);
double y = Math.abs(finishPoint.y - startPoint.y);
if (x > 50 || y > 50)
{
//在这处理滑动
ll_detail.setVisibility(View.GONE);
}
}
}
});
