<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/customdialog" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="20dp" android:minWidth="300dp"> <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/ic_launcher"/> <ListView android:id="@+id/dialoglist" android:layout_width="fill_parent" android:layout_height="wrap_content" /> </LinearLayout>
Java code of the main activity.
