Android的SwipeRefreshLayout空的TextView不正常 [英] Android SwipeRefreshLayout with empty TextView not working properly

问题描述

我想要做的是，让用户刷卡和刷新列表，它并不重要，如果数据有或没有关系。但数据是那里的列表视图时，只有列表视图应该是可见的，而当数据是不存在的，空的TextView应该是可见的。在这两种情况下，用户必须能够通过刷卡来刷新列表。

What i want to do is , allow user to swipe and refresh the list, it does not matter if the data is there or not. But when data is there in the listview only the listview should be visible, and when data is not there , Empty textview should be visible. In both the cases user must be able to refresh list by swipe.

我试图给出一些解决方案 <一href="http://stackoverflow.com/questions/22964934/android-swiperefreshlayout-with-empty-textview">here在这次讨论但没有一个声音的工作中，以两个SwipeToRefresh的思想工作正常，给予这里，但它显示空的容器，甚至在从服务器获取数据。

I tried some solution given here in this discussion but none of them sounds working, the idea of taking two SwipeToRefresh works fine as given Here, but it shows empty container even while fetching data from server.

我想用我自己的逻辑包装ListView和TextView的内相对/的FrameLayout但SwipeToRefresh接受一个观点仅根据其行为

I tried it with my own logic wrapping Listview and Textview inside a Relative/FrameLayout but SwipeToRefresh accepts one view only as per its behavior

下面是一个XML片断我已经尝试过

Here is an xml snippet i have tried

 <android.support.v4.widget.SwipeRefreshLayout
        android:id="@+id/activity_main_swipe_refresh_layout"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="0.945" >


        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent" >

            <ListView
                android:id="@+id/event_list_eventlist"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:divider="@color/event_background"
                android:dividerHeight="1dp" >
            </ListView>

            <TextView
                android:id="@+id/event_txt_nothing_found"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_centerHorizontal="true"
                android:layout_centerInParent="true"
                android:layout_centerVertical="true"
                android:textAppearance="?android:attr/textAppearanceMedium"
                android:textColor="@android:color/darker_gray"
                android:visibility="gone" />
        </RelativeLayout>
    </android.support.v4.widget.SwipeRefreshLayout>

请帮忙

推荐答案

我用的FrameLayout解决同样的问题，看看下面code：

I solved same problem by using FrameLayout, look at below code:

<FrameLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.v4.widget.SwipeRefreshLayout
        android:id="@+id/layout_swipe_refresh"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <ListView
            android:id="@+id/lv_products"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:divider="@null" />

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

    <TextView
        android:id="@+id/tv_no_product"
        style="@android:style/TextAppearance.Medium"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:layout_margin="10dp"
        android:gravity="center"
        android:text="@string/msg_no_listing"
        android:textColor="@color/primary_green"
        android:visibility="gone" />
</FrameLayout>

您可以使用RelativeLayout的为好，但关键是把你的ListView的SwipeRefreshLayout内部，T​​extView的外面。

You could use RelativeLayout as well, but the key is placing your ListView inside the SwipeRefreshLayout, and the TextView outside.
