2. Main. xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:orientation="vertical"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    ><Button      android:layout_width="fill_parent"     android:layout_height="wrap_content"     android:layout_marginTop="5dip"    android:text="customDialog"    android:onClick="customDialog"    /><Button      android:layout_width="fill_parent"     android:layout_height="wrap_content"     android:layout_marginTop="10dip"    android:text="customAlertDialog"    android:onClick="customAlertDialog"    /></LinearLayout>

Note that the onclick attribute is set for both buttons. Check that there are two corresponding methods in the activity code.
