在使用中發(fā)現(xiàn)Switch控件會出現(xiàn)按鈕滑動一點(diǎn)點(diǎn)手指松開后，按鈕停留在手指離開的位置，按鈕既不處于true也不處于false狀態(tài)，此時(shí)也無返回值，而SwitchCompat會判斷此時(shí)滑動位置，將按鈕滑動到底或者返回初始狀態(tài)。 SwitchCompat和Switch大部分xml屬性相同，但是在寫xml屬性是Switch的屬性是以android開頭，而SwitchCompat則是app開頭的，兩者switchTextAppearance的書寫也有所區(qū)別。并且在開發(fā)中發(fā)現(xiàn)，由于SwitchCompat是v7包中的，則必須APP主題是以AppCompat下的，否則無選擇效果，不可點(diǎn)擊。
