was ist der Fehler in diesem Android-Layout xml chunk

Question

Wenn ich versuche, meine app ich eine Runtime bekommen zu debuggen, wenn ich diese XML in meinem Layout enthalten. Ich kann nicht sehen, was daran falsch ist, können Sie? Ich bin mit Android Eclipse-Plugin, 3.5.2 Eclipse, mit der neuesten Android-Plugin und die neuesten Java 6 ... 21 auf winxppro 32-Bit-sp3 Danke.

<ImageButton android:id="@+id/map_button"
  android:src="@drawable/bot_map"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:layout_weight="1"
  />

<ImageButton android:id="@+id/filter_button"
  android:src="@drawable/bot_filter"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:layout_weight="1"
  />

<ImageButton android:id="@+id/sort_button"
  android:src="@drawable/bot_sort"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:layout_weight="1"
  />

<ImageButton android:id="@+id/prev_button"
  android:src="@drawable/bot_arrow_prev"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:layout_weight="1"
  />


<ImageButton android:id="@+id/next_button"
  android:src="@drawable/bot_arrow_next"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:layout_weight="1"
  />

Ich habe auch diese Ausnahmen zur gleichen Zeit:
