Question

我正在开发一款Android应用。我正在使用listview和SwipefreshLayout。但是当我使用SwipefreshLayout刷新列表视图时，加载圈永远不会被隐藏。我在片段中使用它。

这是布局文件

 import Tkinter 
    WindowBox = Tkinter.Tk()
    WindowBox.geometry("250x200")
    WindowBox.title("Welcome to E-UPSR")

    getusername1 = Tkinter.StringVar()
    getpassword1 = Tkinter.StringVar()
    getusername2 = Tkinter.StringVar()
    getpassword2 = Tkinter.StringVar()

    LabelName = Tkinter.Label (WindowBox, text="Username:")
    LabelName.pack()
    TxtBoxName = Tkinter.Entry (WindowBox, textvariable= getusername1)
    TxtBoxName.pack()

    LabelName = Tkinter.Label (WindowBox, text="Password:")
    LabelName.pack()
    TxtBoxName = Tkinter.Entry (WindowBox, textvariable= getpassword1)
    TxtBoxName.pack()

    student=[]


    def read():
        getusername1 = Tkinter.StringVar()
        getpassword1 = Tkinter.StringVar()
        if len(getusername1.get() and getpassword1())== 0:
                labelShowName=Tkinter.Label(WindowBox, text="Invalid").pack()
        else:
            addstudent = open ("student.txt", "w")
            addstudent.read("Username:" + getusername1.get())
            addstudent.read("Password: " + getpassword1.get())
            addstudent.close ()
            WindowBox.withdraw()
            MenuBox.deiconify()   
        return

    def register():
        WindowBox.withdraw()
        RegBox.deiconify()
        return

    RegBox = Tkinter.Tk()
    RegBox.geometry("250x200")
    RegBox.title("register")

    LabelName = Tkinter.Label (RegBox, text="Username:")
    LabelName.pack()
    TxtBoxName = Tkinter.Entry (RegBox, textvariable= getusername2)
    TxtBoxName.pack()
    LabelName = Tkinter.Label (RegBox, text="Password:")
    LabelName.pack()
    TxtBoxName = Tkinter.Entry (RegBox, textvariable= getpassword2)
    TxtBoxName.pack()
    RegBox.withdraw()

    def back():
        RegBox.withdraw()
        WindowBox.deiconify()
        return    


    def save():
        while True:
            getusername2 = Tkinter.StringVar()
            getpassword2 = Tkinter.StringVar()
            if len(getusername2.get() and getpassword2())== 0:
                labelShowName=Tkinter.Label(RegBox, text="Please key-in").pack()
            else:
                addstudent = open ("student.txt", "w")
                addstudent.write('Username:' + getusername2.get())
                addstudent.write('Password:' + getpassword2.get())
                labelShowName=Tkinter.Label(RegBox, text="Done").pack()
        len(getusername2.get() and getpassword2.get())!= 0
        return

    MenuBox = Tkinter.Tk()
    MenuBox.geometry("250x200")
    MenuBox.title("MainMenu")
    MenuBox.withdraw()

    BtnName = Tkinter.Button (RegBox, text="Back", command=back).pack()   
    BtnName = Tkinter.Button (RegBox, text="Enter", command=save).pack()
    BtnName = Tkinter.Button (WindowBox, text="Register", command=register).pack()
    BtnName = Tkinter.Button (WindowBox, text="Proceed", command=read).pack()


    WindowBox.mainloop()

这就是我在片段

中使用它的方式

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
        <android.support.v4.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"
            android:id="@+id/swipe_refresh_layout"
            android:layout_width="match_parent"
            android:layout_height="wrap_content">

            <!-- place your view here -->

            <ListView
                android:dividerHeight="@dimen/list_item_divider_height"
                android:padding="@dimen/list_padding"
                android:divider="@color/whitesmoke"
                android:id="@+id/listview_podcast_list"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"></ListView>

        </android.support.v4.widget.SwipeRefreshLayout>

        <TextView
            android:layout_below="@+id/swipe_refresh_layout"
            android:textSize="17dp"
            android:textStyle="bold"
            android:textColor="@color/black"
            android:textAlignment="center"
            android:id="@+id/tf_no_records"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />

</RelativeLayout>

加载圈永远不会被隐藏回来，如下面的屏幕截图

我的代码有什么问题，如何解决？

Answer 1

刷新后您必须set refreshing到false

refresher.setRefreshing(false);

From doc

<强>更新
科特林：

refresher.isRefreshing = false

SwipeRefreshLayout加载圈未隐藏在Android中
