<? xml version = "1.0" encoding = "utf-8" ?> < selectorxmlns:android = "http://schemas.android.com/apk/res/android" > < itemandroid:state_pressed = "true" android:drawable = "@drawable/button_pressed" /> < itemandroid:state_focused = "true" android:drawable = "@drawable/button_pressed" /> < itemandroid:drawable = "@drawable/button_normal" /> </ selector > |

< LinearLayout android:layout_height = "wrap_content" android:layout_width = "wrap_content" android:clickable = "true" <!--这条是必须的,否则没有高亮显示效果,这有别于自动的button,textview等其他控件--> android:background="@drawable/linearlayout_background"> < Button ....../> < TextView ...../> </ LinearLayout > |
希望本文所述对大家Android程序设计有所帮助。
