單選開關

TextView兩圖片實現點擊切換開關效果：

    //xml
    <TextView
                android:id="@+id/iv_reason"
                android:layout_width="wrap_content"

                android:gravity="center"
                android:text="推送時間造成困擾" />

    initSwitcher(iv_reason, "on"); //初始
    String value = (iv_reason.getTag() != null) && ((String) iv_reason.getTag()).equals("off") ? "2" : "1"; //取值

ImageView、Button兩圖片實現點擊切換開關效果：

    <Button

                android:background="@drawable/ic_feedback_submit_n"
                android:gravity="center"/>

        // ImageView
        final String[] tags = {"on", "off"};
        final ImageView iv_send = (ImageView) v.findViewById(R.id.iv_send);
        iv_send.setTag(tags[0]); //init
        iv_send.setOnClickListener(new OnClickListener() {
