Question

In a TabHost, I’m setting up a TabSpec that consists of a header area with a few buttons and below, a ListView. The Activity to manage this TabSpec is defined as “extends ListActivity”.
However, now I’m running into the problem of not being able to define an OnClickListener to check for the submit button pressed. How can I solve that?

Trying to cast the Button by

btnRatingSubmit.setOnClickListener((OnClickListener) this);

raises an ClassCastException…

Here is a basic excerpt of the layout:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >

<RatingBar
    android:id="@+id/ratingBar"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

<EditText
    android:id="@+id/edComment"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:inputType="textMultiLine" >
</EditText>

<Button
    android:id="@+id/btnSubmit"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/btnSubmit" />

<ListView
    android:id="@android:id/list"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" />

</LinearLayout>

Answer 1

Instead of

btnRatingSubmit.setOnClickListener((OnClickListener) this);

try this:

btnRatingSubmit.setOnClickListener(new View.OnClickListener(){

public void onClick(View v) {
            // TODO Auto-generated method stub

        }
    });
