i want when wifi connection established. have broadcastreceiver works prefectly receiving network_state_changed_action , scan_results_available_action, not supplicant_connection_change_action. 1 harder test: turn off/on router that. protected void oncreate(bundle savedinstancestate) { receiverwifi = new wifireceiver(); intentfilter intentfilter = new intentfilter(); intentfilter.addaction(wifimanager.supplicant_connection_change_action); intentfilter.addaction(wifimanager.network_state_changed_action); intentfilter.addaction(wifimanager.scan_results_available_action); registerreceiver(receiverwifi, intentfilter); //... } class wifireceiver extends broadcastreceiver { public void onreceive(context c, intent intent) { final string action = intent.getaction(); log.d("mhp","*broadcastreceiver: " + action")} and manifiest.xml &l

i have created graph using networkx. drawing graph using graphviz, these lines of code: pos = nx.graphviz_layout(g2, prog='neato', args='-goverlap=prism') plt.figure(figsize=(10, 14)) nx.draw(g2, pos, node_size=sizes, alpha=1, nodelist=nodes, node_color=colors, with_labels=true, labels=labeldict, font_size=8) the graph consists of "backbone" of few larger nodes, attached few hundred smaller nodes. i have used args='-goverlap=prism' (in first line of code above) space out graph, has created problem. matters more larger nodes spaced out, but, because of how many small nodes there are, of larger nodes ending crammed together. my thoughts on solution generate graph larger nodes ensure spaced, add smaller nodes graph without changing layout of original nodes. have done research, , seems tricky add new nodes without changing old ones in graphviz. possible "pin" nodes, unsure of how within networkx. this graph looks like:

i want follow mvvm pattern as possible , don't know if doing navigation quite well. note using masterdetail page , want maintain master page, changing detail side when navigate. here way navigate viewmodel . in example, viewmodelone viewmodeltwo : public class viewmodelone : viewmodelbase { private void gotoviewtwo() { var viewtwo = new viewtwo(new viewmodeltwo()); ((masterview)application.current.mainpage).navigatetopage(viewtwo); } } masterview implementation: public class masterview : masterdetailpage { public void navigatetopage(page page) { detail = new navigationpage(page); ispresented = false; } } viewtwo implementation: public partial class viewtwo : pagebase { public menuview(viewmodeltwo vm) : base(vm) { initializecomponent(); } } pagebase implementation: public class pagebase : contentpage { public pagebase(viewmodelbase vmb) { this.bindingcontext

i have been familiar tabhost/tabspec create application tabs. noticed there more 1 option create tabs: 1- tabs in action bar 2- viewpager (i guess google calls horizontal pager) 3- , offcourse tabhost/tabspec approach. i tried read google docs everywhere got further confused. when use or there 1 norm? thanks you should use toolbar viewpager simulate tabs (all wrapped in appbarlayout). result this: you can read more type of design on material design spec: https://www.google.com/design/spec/components/tabs.html#tabs-usage also, here tutorial on how implement tabs within viewpager: http://blog.grafixartist.com/material-design-tabs-with-android-design-support-library/
