zooming - How to implement the android zoomview? -


i want implement android-zoom-view (https://code.google.com/p/android-zoom-view/). added jar buildpath. created following xml: 

<?xml version="1.0" encoding="utf-8"?> <pl.polidea.view.zoomview xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" >       <imageview         android:id="@+id/webcam1"         android:layout_width="match_parent"         android:layout_height="match_parent"         android:layout_gravity="center"         android:layout_marginbottom="20dp"         android:scaletype="matrix" />      <imageview         android:id="@+id/webcam2"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_gravity="center"         android:scaletype="matrix" /> </pl.polidea.view.zoomview>

and added following code activity:

    view v = ((layoutinflater) getsystemservice(context.layout_inflater_service))             .inflate(r.layout.zoomable_view, null, false);     v.setlayoutparams(new linearlayout.layoutparams(             layoutparams.fill_parent, layoutparams.fill_parent));      zoomview = new zoomview(this);     zoomview.addview(v);      linearlayout main_container = (linearlayout) findviewbyid(r.id.linearlayout1);     main_container.addview(zoomview);

what doing wrong? following error:

caused by: android.view.inflateexception: binary xml file line #2: error inflating class pl.polidea.view.zoomview

i added following constructor zoomview class , works @ least 1 imageview in zoomview.

public zoomview(final context context, attributeset attr) {      super(context, attr);      }
