我正在开发一个Android应用程序，其中包含一个包含Mapview的片段... mapview包含根据本地数据库中位置的标记。 有没有办法动画甚至改变只点击标记的颜色？ 我的意思是我已经在setOnMarkerClickListener中完成了它，但是，当我点击另一个标记时，前一个标记仍然是相同的颜色/动画......
添加以下代码的主要部分......
String myPath = DB_PATH + DB_NAME;
myDataBase = SQLiteDatabase.openDatabase(myPath, null, SQLiteDatabase.OPEN_READWRITE);
Cursor c = myDataBase.rawQuery("Select * from location", null);
if (c != null) {
if (c.moveToFirst()) {
do {
id = c.getInt(0);
if (userPrefs.getString("locale",null)==null || userPrefs.getString("locale",null).equals("en"))
{
storename = c.getString(1);
}
else {
storename = c.getString(7);
}
stlatitude = c.getDouble(2);
stlongitude = c.getDouble(3);
city = c.getString(4);
String emirate = c.getString(5);
storeloc = new Location("StoreLocation");
storeloc.setLatitude(stlatitude);
storeloc.setLongitude(stlongitude);
addmarker();
}
while (c.moveToNext());
}
}
myDataBase.close();
map.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener() {
@Override
public boolean onMarkerClick(Marker marker) {
String s= marker.getTitle();
String snippet= marker.getSnippet();
markerlat= marker.getPosition().latitude;
markerlong= marker.getPosition().longitude;
marker.setIcon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_RED));
tv.setText(s);
tv1.setText(snippet);
if (s.equals(getActivity().getResources().getString(R.string.here))) {
if (relbutton.getVisibility() == View.VISIBLE && reltext.getVisibility() == View.VISIBLE) {
relbutton.setAlpha(1.0f);
relbutton.animate().translationY(0).alpha(0.0f);
relbutton.setVisibility(View.GONE);
} else if (relbutton.getVisibility() != View.VISIBLE && reltext.getVisibility() != View.VISIBLE) {
reltext.setVisibility(View.VISIBLE);
reltext.setAlpha(0.0f);
reltext.animate().translationY(0).alpha(1.0f);
if (userPrefs.getString("locale",null).equals("ar"))
{
RelativeLayout relativeLayout = (RelativeLayout) view.findViewById(R.id.relativeLayout2);
relativeLayout.setGravity(Gravity.LEFT);
RelativeLayout relativeLayout1 = (RelativeLayout) view.findViewById(R.id.relativeLayout1);
relativeLayout1.setGravity(Gravity.RIGHT);
}
}

return true;

你可以创建不同颜色名称的arraylist 在oncreateView中使用这些行..
并保持整数int的值color_value = 0; 并在标记点击事件上增加这些值;
int color_value = 0;
ArrayList<String> colours = new ArrayList<String>();
colours.add("HUE_RED");
colours.add("HUE_BLACK");
colours.add("HUE_BLUE");
colours.add("HUE_PINK");
colours.add("HUE_GRAY");
colours.add("HUE_YELLOW");
.
.
.
.
.
colours.add("HUE_GREEN");
和onMarkerClickListener使用以下代码行并增加color_value的值;
public boolean onMarkerClick(Marker marker) {
for(int i =0;i<=colours.size();i++)
{
if(color_value==i)
{
if(color_value==colours.size)
{
colur_value=0;
}
else
{
color_value++;//increment the value of color from here
}
marker.setIcon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.colours.get(i)));
break;
}
}
}

我已经通过更改onmarkerclick代码来解决了解决方案......
public boolean onMarkerClick(Marker marker) {
String s= marker.getTitle();
String snippet= marker.getSnippet();
markerlat= marker.getPosition().latitude;
markerlong= marker.getPosition().longitude;
if(prevmarker!=null){
if(!prevmarker.getTitle().equals(getActivity().getResources().getString(R.string.here)))
{
prevmarker.setIcon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_VIOLET));
}
}
if (!s.equals(getActivity().getResources().getString(R.string.here))) {
marker.setIcon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_RED));
}

首先在oncreate上定义标记，如下所示
makerDefault = this.getResources（）。getDrawable（R.drawable.marker_default）;
之后使用这个课程 私有类MyItemizedOverlay扩展了ItemizedOverlay {
private List<OverlayItem> mOverlays = new ArrayList<OverlayItem>();
public MyItemizedOverlay(Drawable defaultMarker) {
super(boundCenterBottom(defaultMarker));
}
public void addOverlayItem(int lat, int lon, String title, Drawable altMarker) {
GeoPoint point = new GeoPoint(lat, lon);
OverlayItem overlayItem = new OverlayItem(point, title, null);
addOverlayItem(overlayItem, altMarker);
}
public void addOverlayItem(OverlayItem overlayItem) {
mOverlays.add(overlayItem);
populate();
}
public void addOverlayItem(OverlayItem overlayItem, Drawable altMarker) {
overlayItem.setMarker(boundCenterBottom(altMarker));
addOverlayItem(overlayItem);
}
@Override
protected OverlayItem createItem(int i) {
return mOverlays.get(i);
}
@Override
public int size()
{
return mOverlays.size();
}
@Override
protected boolean onTap(int index) {
// Toast.makeText(LocationActivity.this, getItem(index).getTitle(), Toast.LENGTH_LONG).show();
Intent intent=new Intent(LocationActivity.this, PlaceOrderActivity.class);
intent.putExtra("shop_no", getItem(index).getTitle());
startActivity(intent);
return true;
}
}
之后绑定你的数据就像这样 MyItemizedOverlay itemizedOverlay = new MyItemizedOverlay（makerDefault）;
JSONArray array= new JSONArray(data);
String da=String.valueOf(array.length());
Log.d("da", da);
for(int i=0;i<array.length();i++){
JSONObject jsonObject = array.getJSONObject(i);
Log.d("jsonObject", jsonObject.toString());
shopname=jsonObject.getString("0");
latitude=jsonObject.getString("1");
longitude=jsonObject.getString("2");
shop_no=jsonObject.getString("3");
Log.d("shopname", shopname);
mc = mapView.getController();
double dbl_latitude = Double.parseDouble(latitude);
int Lat = (int)(dbl_latitude * 1E6);
double dbl_longitude = Double.parseDouble(longitude);
int Lon = (int)(dbl_longitude* 1E6);
itemizedOverlay.addOverlayItem(Lat, Lon, shop_no, makerDefault);
mapView.getOverlays().add(itemizedOverlay);
mc.setCenter(new GeoPoint(Lat, Lon));
//Toast.makeText(getApplicationContext(), Lat+""+Lon, 3000).show();
mc.zoomToSpan(itemizedOverlay.getLatSpanE6(), itemizedOverlay.getLonSpanE6());
在这里你必须用你想要的颜色放置多个图像
