I have a custom listview which is filled with webview. I want to use the pinch zoom in/Zoom out for my webview. But i m not getting the pinch zoom in/out flexibly when i m pinching the webview it is triggering the listview's scrolling up and down.
how can I handle the scroll UP/DOWN event for the listview and pinch for webview simultaneously .
here is my listview_layout.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" >
ListView
android:id="@+id/listReader"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:layout_below="@+id/readerHeader"
android:divider="@android:color/background_dark"
android:dividerHeight="5dp" >
</ListView>
here is my webview_layour.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<WebView
android:id="@+id/webView1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:clickable="true"
android:focusable="false"
android:focusableInTouchMode="false"
android:scrollbars="none" />
</RelativeLayout>
and here is my java file
