android – scrolling up in webview causes refresh by SwipeRefreshLayout

Questions:

I have a WebView inside a FrameLayout, to add tabs because i am creating a browser. The FrameLayout is inside a SwipeRefreshLayout.

The problem: Whenever i scroll the content up fast in the WebView, the refresh icon appears from behind the toolbar. It should only happen when the WebView content is at the top. It has something to do with the FrameLayout, when i remove it, the issue is gone.

The layout looks like this:

<SwipeRefreshLayout
            android:id="@+id/swipeRefresh"
            android:layout_width="match_parent"
            android:layout_height="match_parent" >

        <FrameLayout
        android:id="@+id/webViewFrame"
        android:layout_width="match_parent"
        android:layout_height="match_parent"    
        >
        <WebView
            android:id="@+id/webView"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />
        </FrameLayout>

</SwipeRefreshLayout>
How to&Answers:

Just implement your Fragment or Activity with ViewTreeObserver.OnScrollChangedListener then set Listener like webview.getViewTreeObserver().addOnScrollChangedListener(this);

In onScrollChanged() method do like this

@Override
public void onScrollChanged() {
    if (webview.getScrollY() == 0) {
        swipeLayout.setEnabled(true);
    } else {
        swipeLayout.setEnabled(false);
    }
}

Answer:

No Solution worked for me. Here is my approach.

 @Override
 public boolean dispatchTouchEvent(MotionEvent event)
 {
super.dispatchTouchEvent(event);
int x = (int)event.getX();
int y = (int)event.getY();
 if(y>800){
     swipeRefreshLayout.setEnabled(false);
 }else {
     swipeRefreshLayout.setEnabled(true);
 }


return false;
}
