geocoding in android map -

-

hi..i doing geocoding in android map.(i.e)getting address input user & locate particular point using marker.how this?

my code

simplegooglemaps.java

public class simplegooglemaps extends mapactivity {  geocoder geocoder=null; mapview mapview=null;  @override protected boolean islocationdisplayed(){ return false; } @override protected boolean isroutedisplayed(){ return false; } @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate);  setcontentview(r.layout.main); mapview=(mapview)findviewbyid(r.id.map); mapview.setbuiltinzoomcontrols(true);  button geobtn=(button)findviewbyid(r.id.geocodebtn); geocoder=new geocoder(this); geobtn.setonclicklistener(new onclicklistener(){ @override public void onclick(view srg0){  try{ edittext loc=(edittext)findviewbyid(r.id.location); string locationname=loc.gettext().tostring(); list<address>addresslist=geocoder.getfromlocationname(locationname,5); if(addresslist!=null && addresslist.size()>0) {  int lat=(int)(addresslist.get(0).getlatitude()*1000000);  int lng=(int)(addresslist.get(0).getlongitude()*1000000);  geopoint pt=new geopoint(lat,lng); mapview.getcontroller().setzoom(15); mapview.getcontroller().setcenter(pt); } }catch(ioexception e){ e.printstacktrace(); } }}); } }

xml file is

<?xml version="1.0" encoding="utf-8"?> <relativelayout xmlns:android= "http://schemas.android.com/apk/res/android"     android:layout_width="fill_parent"     android:layout_height="fill_parent">  <linearlayout android:layout_width="fill_parent" android:layout_alignparentbottom="true" android:layout_height="wrap_content" android:orientation="vertical">  <edittext android:layout_width="fill_parent"  android:id="@+id/location" android:layout_height="wrap_content" /> <button android:id="@+id/geocodebtn" android:layout_width="wrap_content" android:layout_height="wrap_content"  android:text="find"/> </linearlayout>  <com.google.android.maps.mapview android:id="@+id/map" android:clickable="true" android:layout_width="fill_parent" android:layout_height="320px" android:apikey= "0jfvbxbxshkp6h-xycpor1hw_yawrkng5eumx0g"/> </relativelayout>

i want make logharitmic fit. keep getting runtime error: optimal parameters not found: number of calls function has reached maxfev = 1000 i use following script. can tell me go wrong? use spyder still beginner. import math import matplotlib mpl scipy.optimize import curve_fit import numpy np #data f1=[735.0,696.0,690.0,683.0,680.0,678.0,679.0,675.0,671.0,669.0,668.0,664.0,664.0] t1=[1,90000.0,178200.0,421200.0,505800.0,592200.0,768600.0,1036800.0,1371600.0,1630800.0,1715400.0,2345400.0,2409012.0] f1n=np.array(f1) t1n=np.array(t1) plt.plot(t1,f1,'ro',label="original data") # curvefit def func(t,a,b): return a+b*np.log(t) t=np.linspace(0,3600*24*28,13) popt, pcov = curve_fit(func, t, f1n, maxfev=1000) plt.plot(t, func(t, *popt), label="fitted curve") plt.legend(loc='upper left') plt.show() your original data t1 , f1 . therefore curve_fit should given t1 second argument, not t . popt, pcov = curve_fit(func,...

binding - How can you make the color of elements of a WPF DrawingImage dynamic? -

-
we have need make vector graphic images change color of elements within graphic @ runtime. seem setting colors based on either static or dynamic resource values wouldn't work. want have multiple versions of same graphic, each abilty set graphic elements (path, line, etc) different colors don't think dynamic resource approach work. leaves data binding seems right approach. update graphic use data binding expr instead of hard-coded brush color so: <drawingimage x:key="graphic1"> <drawingimage.drawing> <drawinggroup> <drawinggroup.children> <geometrydrawing geometry="f1 m 8.4073,23.9233l"> <geometrydrawing.pen> <pen linejoin="round" brush="{binding line1brush, mode=oneway}"/> </geometrydrawing.pen> </geometrydrawing> <geometrydrawing geometry="f1 m 3.6875,2.56251l"> <geometrydrawing....
