TestActivity.java

public class TestActivity extends Activity {
private Button btnConfirm;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        btnConfirm = (ConfirmButton)findViewById(R.id.confirmButton1);

        btnConfirm.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                btnConfirm.setEnabled(false);
            }
        });
    }
}

public class ConfirmButton extends Button{

    public ConfirmButton(Context context) {
        super(context);
    }

    public ConfirmButton(Context context, AttributeSet attrs) {
        this(context, attrs, R.layout.confirm__button);
    }

    public ConfirmButton(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }
}

I do not understand why the btnConfirm has no buttonConfirm style.

you are not using custom button

Just casting to your ConfirmButton won't "change" the type of the button. You need change to change your XML to actually reference your class. I don't know your package but,

go for this:

<com.your.package.TestActivity$ConfirmButton xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/ConfirmButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    style="@style/buttonConfirm"  >
</com.your.package.TestActivity$ConfirmButton>

You should also EITHER make ConfirmButton a static class, or move it up into a class of it's own.
