Android: Button on an WebView-Element (.png-Image) -

i need create floorplan can scrolled , zoomed.some sections of plan shall linked other activities (ie. kitchen). idea lay simple button on kitchen-region. click on can kitchen activity.

because of scrolling- , zooming-requirement created webview containing floorplan:

<linearlayout xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@drawable/background" android:paddingbottom="@dimen/activity_vertical_margin" android:paddingleft="@dimen/activity_horizontal_margin" android:paddingright="@dimen/activity_horizontal_margin" android:paddingtop="@dimen/activity_vertical_margin" tools:context=".floorplanactivity"      xmlns:android="http://schemas.android.com/apk/res/android">  <webview     android:id="@+id/webviewfloorplan"     android:layout_width="fill_parent"     android:layout_height="fill_parent"     android:layout_alignparentleft="true"     android:layout_alignparenttop="true" >      <button         android:id="@+id/buttonkuehltheke"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:text="button" />  </webview>  </linearlayout>  

but i'm not able lay button on specific region on floorplan. button appears in upper left corner of floorplan.

mainactivity-code:

    webview wvfloorplan = (webview) findviewbyid(r.id.webviewfloorplan);     wvfloorplan.getsettings().setbuiltinzoomcontrols(true);     wvfloorplan.loadurl("file:///android_asset/services_plan.png"); 

what needs done set button every postition on webview (floorplan)?

thx arne

if going scrolling , zooming webview, coordinates kitchen section going dynamic, positioning button on difficult.

i suggest overriding webview.shouldoverrideurlloading. way can use html create link kitchen activity.

wvfloorplan.setwebviewclient(new webviewclient() {     @override     public boolean shouldoverrideurlloading(webview view, string url) {         if (url.startswith("act:")) {             intent intent = new intent( <kitchen activity> );             startactivity(intent);             return true;         }         return false;     } }); 

you have write html wrapper around image map parts of images different links coordinates static. instead of http urls use href="act:kitchen"
