尝试使用SlidingToggleSwithView

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:switch="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="de.nitri.slidingtoggleswitchdemo.MainActivity$PlaceholderFragment" >

    <de.nitri.slidingtoggleswitch.SlidingToggleSwitchView
        android:id="@+id/sliding_toggle_switch"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textColor="#ff000000"
        switch:leftButtonText="@string/left_button_text"
        switch:rightButtonText="@string/right_button_text" />

    <TextView
        android:id="@+id/textView1"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="center"
        android:textAppearance="?android:attr/textAppearanceLarge" />

</LinearLayout>

主 Activity .java

public class MainActivity extends FragmentActivity implements OnToggleListener {
    //...

    @Override
    public void onToggle(int result) {
        if (result == SlidingToggleSwitchView.LEFT_SELECTED)
            //...
        else
            //...
    }

}
