android:layout_width="match_parent" 裏為什麽總是提示match_parent的類型不匹配

妳的版本太低了要2.2才可以用match_paren，妳只能用fill_parent

fill_parent -1 The view should be as big as its parent (minus padding). This constant is deprecated starting from API Level 8 and is replaced by match_parent.

match_parent -1 The view should be as big as its parent (minus padding). Introduced in API Level 8.

wrap_content -2 The view should be only big enough to enclose its content (plus padding).
