序：今天項目中用到了開關按鈕控件，查閱了一些資料特地寫了這篇博客記錄下。

1.Switch

        <Switch
            android:id="@+id/bt"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textOn="開啟"
            android:layout_marginLeft="20dp"
            android:textOff="關閉"
            android:showText
 
="true"
            android:thumb="@drawable/shape_thum"
            android:track="@drawable/select_bg_switch"
            />

這裏layout_width:這能設置整個布局的寬度，不能設置具體的Switch的大小，需要使用switchMinWidth屬性來設置。

thumb：文字所攜帶的背景，設置為背景色進行隱藏。不設置會出現一個背景框。

track：設置開關的背景圖片，類似於button的background。

textoff、texton：設置開關時的文字顯示。

2.ToggleButton

<ToggleButton
            android:layout_width="80dp"
            android:layout_height="20dp"
            android:id="@+id/toggle"
            android:layout_centerHorizontal="true"
            android:background="@drawable/shape_track_on"
            android:textOff="off"
            android:textOn
 
="on"
            android:layout_marginLeft="20dp"

            />
