Onclick not working on parent cardview

[ram-readwhere]

Parent cardview is not taking onclick event. if MathView is replaced with plain TextView, then it is working fine.

I am registering onclick as

cvAns.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {   }
            });

And layout file is as

<android.support.v7.widget.CardView
    xmlns:card_view="http://schemas.android.com/apk/res-auto"
    android:id="@+id/cvAns"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    card_view:cardUseCompatPadding="true"
    card_view:cardElevation="1dp"
    card_view:cardCornerRadius="1dp"
    android:foreground="?android:attr/selectableItemBackground"
    android:clickable="true"
    card_view:cardBackgroundColor="@color/white">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:padding="5dp">

        <android.support.v4.widget.NestedScrollView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:scrollbars="none">

            <io.github.kexanie.library.MathView
                android:id="@+id/tv_ans"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                auto:engine="KaTeX" />
        </android.support.v4.widget.NestedScrollView>

    </RelativeLayout>

</android.support.v7.widget.CardView>

It seems that MathView, which inherits from WebView, consumes the touch event, this post gave an explanation about this. I just made a quick fix, try upgrade to the newer version 0.0.6 and test if this works for you!

Hi kexanie, I tried with latest version 0.0.6 but that didn't work.

Do I need to make any changes in my xml or onclick listener?

@ram-readwhere I found that NestedScrollView also consumed the touch event, so just removing the outter NestedScrollView should fix this.

Hi kexanie,

It is working fine now. Thanks for quick fix.

this disable copy feature, so for those who want to copy text should downgrade to 0.0.5 version
