CardView does not indicate it is being clicked

Question

I have a layout with 4 cards arranged vertically, and what I would like is t have a click listener for each. Below is my entire layout:

<RelativeLayout
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"

The issue I have is in my activity I simply have a click listener:

card1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick( View v) {
                Log.d("NICK","Card 1 clicked.");
                ...................
        });

and I have this exactly the same for the other 3 cards. When testing I only see confirmation in my logcat that the first card is being clicked. Is there something I am missing to have click listeners for the other 3 cards?

Answer 1

The android:OnClick="method" needed to be inside the TextView child of each CardLayout.

Answer 2

You will need a click listener for each of the button elements you are wanting to monitor. You will need to use a unique listener for each (or at least make sure you set the listener on each view).

Answer 3

You have not defined an on click attribute for each card. Before you can listen for clicks you must add:

<!-- XML code for each card -->
android:onClick="method"

where method is the name of the method in the appropriate java activity to handle the click. You must have a method in your java corresponding to the onClick method name:

// java code in activity
public void method(View V) {
    // some code on click
}

This may be the easiest way to go about this.
