Question

我会用几句话来解释我的问题。所以我正在解析一些＆＃34; web＆＃34;数据到列表视图中。但在我获取所有数据之前，我想显示一个进度条（微调器），其中（当加载数据时）列表视图将在以后显示。因此，当活动开始时我显示微调器，当获取数据时，我使微调器消失。我认为我在我的xml文件中做了一些错误。

如果我有这样的话，应用程序崩溃IOException Broken Pipe：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

        <RelativeLayout
        Some stuff   
        </RelativeLayout>

        <RelativeLayout
        Some stuff
        </RelativeLayout>

        <ListView
            android:layout_below="@+id/map"
        </ListView>

        <ProgressBar
            android:layout_below="@+id/map"
        />

        <include layout="@layout/footer" />

    </RelativeLayout>

如果我喜欢这个，微调器会显示，但列表视图不会出现：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    <RelativeLayout
    Some stuff   
    </RelativeLayout>

    <RelativeLayout
    Some stuff
    </RelativeLayout>

    <ProgressBar
        android:layout_below="@+id/map"
    />

    <ListView
        android:layout_below="@+id/map"
    </ListView>

    <include layout="@layout/footer" />

</RelativeLayout>
