Android進(jìn)階之路 - selector狀態(tài)選擇器
ViewStateUtil工具類
public class ViewStateUtil {
/*//設(shè)置是否按壓狀態(tài)，一般在true時設(shè)置該屬性，表示已按壓狀態(tài)，默認(rèn)為false
android:state_pressed
//設(shè)置是否選中狀態(tài)，true表示已選中，false表示未選中
android:state_selected
//設(shè)置是否勾選狀態(tài)，主要用于CheckBox和RadioButton，true表示已被勾選，false表示未被勾選
android:state_checked
//設(shè)置勾選是否可用狀態(tài)，類似state_enabled，只是state_enabled會影響觸摸或點擊事件，state_checkable影響勾選事件
android:state_checkable
//設(shè)置是否獲得焦點狀態(tài)，true表示獲得焦點，默認(rèn)為false，表示未獲得焦點
android:state_focused
//設(shè)置觸摸或點擊事件是否可用狀態(tài)，一般只在false時設(shè)置該屬性，表示不可用狀態(tài)
